1. About these terms

1.1 These terms set out the warranty given by NoxWorks Ltd, a company registered in England and Wales under company number 16826255 ("NoxWorks", "we", "us", "our"). Our registered office address is shown on the Companies House register, and you can contact us at [email protected].

1.2 This warranty is a guarantee within the meaning of section 30 of the Consumer Rights Act 2015. It is provided free of charge and is in addition to, and does not affect, your statutory rights (see clause 19).

1.3 This warranty applies to night vision devices assembled and sold by NoxWorks and purchased from us or from an authorised NoxWorks reseller. It applies to Devices used and serviced within the United Kingdom.

1.4 Please read these terms together with the user manual supplied with your Device. Failure to follow the user manual may affect your cover (see clause 11).

2. Definitions

In these terms:

"Baseline Specification" means the specification of the image intensifier tube recorded at the time of build, as described in clause 14.1.

"Components" means the parts of the Device, including the image intensifier tube, housing, objective and eyepiece lenses, and electronic parts.

"Defect" means a fault in materials or manufacture that appears under Normal Use.

"Device" means a complete night vision device assembled by NoxWorks and identified by a NoxWorks serial number.

"Normal Use" means use in line with the user manual, within the Device's stated operating conditions, and for its intended and lawful purpose.

"Original Proof of Purchase" means the NoxWorks invoice or order confirmation, or the authorised reseller's receipt, issued to the original purchaser.

"Purchase Date" means the date on which the Device was originally bought from NoxWorks or an authorised reseller, as shown on the Original Proof of Purchase.

"Registered Owner" means the original purchaser or, where the Device has been transferred, the most recent owner correctly recorded in the Transfer Log.

"Transfer Log" means the NoxWorks warranty transfer record supplied with the Device, which must be kept with the Device at all times, as described in clause 8.

"Tube Failure" has the meaning given in clause 14.2.

"Warranty Documentation" means the documents listed in clause 9.1.

"Workmanship" means the assembly work carried out by NoxWorks as described in clause 4.

3. Device warranty: 1 year

3.1 We warrant that the Device, including all Components, will be free from Defects for one (1) year from the Purchase Date.

3.2 Image intensifier tubes are covered under this clause on the terms set out in clause 14.

3.3 Devices with a Purchase Date before 2 November 2026 keep the two (2) year device warranty that applied when they were bought.

4. Workmanship guarantee: 10 years

4.1 We guarantee our Workmanship for ten (10) years from the Purchase Date. Workmanship means:

(a) tube installation: the fitting, seating and electrical connection of the image intensifier tube;

(b) collimation and alignment: the alignment of binocular Devices as originally built;

(d) electrical work: wiring, soldered joints, contacts and connections made by NoxWorks;

(e) mechanical assembly: fasteners, thread locking and bonded joints made by NoxWorks; and

(f) initial seal and purge: seals fitted and nitrogen purging carried out by NoxWorks.

4.2 Cover under clause 4.1(f) lasts for two (2) years from the Purchase Date only, because seals and O-rings deteriorate naturally over time. Re-sealing and re-purging after that period are available as a chargeable service.

4.3 This guarantee covers only faults caused by the way NoxWorks assembled the Device. It does not extend the warranty on Components beyond the period in clause 3.

4.4 Whether a fault is caused by our Workmanship will be determined by our inspection under clause 10. We will act reasonably and give you a written explanation of our findings.

5. Housing warranty: lifetime

5.1 If the housing of the Device suffers a structural failure under Normal Use, we will repair or replace the housing for the lifetime of the Device. Structural failure includes cracking of the housing body, failure of a hinge or articulation, or failure of a mount interface.

5.2 For this clause, "lifetime" means for as long as the Device remains in service and the housing, or a reasonable equivalent, remains available. If no equivalent replacement is available, we will offer a repair, a suitable alternative housing, or a credit towards a replacement, at our discretion and acting reasonably.

5.3 This clause does not cover cosmetic wear, finish wear, impact damage, or damage caused by mounting, accessories or excessive force.

6. What we will do

6.1 If a valid claim is made under clauses 3, 4 or 5, we will, at our option, repair the Device, replace the affected Component, or replace the Device with one of the same or better specification. Claims relating to the image intensifier tube will be dealt with under clause 14.

6.2 Replacement parts may be new or of equivalent-to-new performance. Replaced parts become our property.

6.3 Repaired or replacement items are warranted for the remainder of the original warranty period applying to them.

6.4 We will pay to return the Device to the Registered Owner's UK address after a valid warranty repair or replacement.

6.5 We will carry out warranty work within a reasonable time and keep you informed of progress. Where a Component must be sourced from a third party, we will tell you of any expected delay.

7. Who can claim

7.1 Claims under this warranty may be made only by the Registered Owner.

7.2 If the Device has changed hands and the transfer has not been recorded in the Transfer Log under clause 8, the warranty does not pass to the new owner, and the Device will be treated as out of warranty. Out-of-warranty repairs remain available under clause 13.

8. Transfer of warranty

8.1 This warranty may be transferred to a later owner of the Device only if all of the following conditions are met:

(a) the Transfer Log is fully completed at the time of transfer, recording: (i) the Device serial number; (ii) the date of transfer; (iii) the name and contact details of the previous owner and the new owner; and (iv) the signatures of both the previous owner and the new owner;

(b) the Transfer Log, the Original Proof of Purchase and all other Warranty Documentation are passed to the new owner with the Device; and

(c) the transfer complies with all applicable laws, including UK export controls and any restrictions on the sale or transfer of controlled goods.

8.2 The Transfer Log must be kept with the Device at all times. It does not need to be sent to NoxWorks at the time of transfer.

8.3 A transfer does not restart or extend any warranty period. All periods continue to run from the original Purchase Date.

8.4 Night vision devices are controlled goods. A Device must not be transferred, sold or exported in breach of export control or sanctions law (see clause 17). We will not provide warranty service where we reasonably believe a transfer has breached such law.

8.5 If the Transfer Log is lost or damaged, the original purchaser or the most recently recorded owner may request a replacement from us. We may ask for reasonable evidence of ownership before issuing one. A Device whose ownership history cannot be reasonably established may be treated as out of warranty.

9. Documentation

9.1 The Warranty Documentation for a Device consists of:

(a) the Original Proof of Purchase;

(b) the NoxWorks warranty card or build certificate showing the Device serial number and the Baseline Specification;

(d) any service records issued by NoxWorks.

9.2 When making a claim, you must supply all Warranty Documentation with the Device. Copies, including clear photographs or scans, are acceptable for the Original Proof of Purchase and the Transfer Log. The original Transfer Log should stay with you.

9.3 If the Warranty Documentation is incomplete, we may ask you to supply the missing documents before we begin work. If the Registered Owner or the Purchase Date cannot be reasonably established, we may treat the claim as out of warranty.

9.4 Any original documents you send will be returned with the Device, together with an updated service record of the work carried out.

10. How to make a claim

10.1 To make a claim, contact us through our contact page or at [email protected], giving the Device serial number, the Registered Owner's details and a description of the fault.

10.2 We will confirm whether the claim appears to be covered and give you return instructions and a returns reference. You must not send the Device to us until we have done so.

10.3 You must package the Device securely, preferably in its original case, and include the returns reference and all Warranty Documentation (clause 9). Copies or photographs of the Transfer Log and proof of purchase are acceptable.

10.4 If a fault is reported within six (6) months of the Purchase Date, we will pay the cost of sending the Device to us. After that period, you are responsible for the cost of sending the Device to us. We recommend an insured, tracked service, as we cannot accept responsibility for Devices lost or damaged in transit to us.

10.5 We will inspect every returned Device and record our findings against its serial number.

10.6 If we find the fault is covered, we will proceed under clause 6 or clause 14, as applicable. If we find the fault is not covered, we will tell you why in writing and give you a quotation before carrying out any work. If you decline the quotation, we will return the Device to you, and return postage will be at your cost.

11. Exclusions

11.1 This warranty does not cover any fault, damage or deterioration caused by:

(a) accident, drop, impact, misuse, neglect, or failure to follow the user manual;

(b) exposure of the image intensifier tube to daylight, excessive light or lasers (see clause 14);

(c) the Device being opened, adjusted, modified or repaired by anyone other than NoxWorks, including removal of the tube or eyepieces, adjustment of collimation, or removal or damage of serial labels or seals;

(d) use with incompatible, faulty or poor-quality equipment, mounts, power sources or accessories;

(e) batteries, including leakage, corrosion, storage of the Device with batteries fitted, or use of rechargeable batteries where not specified;

(f) water ingress where the Device has been used beyond its stated environmental rating, or where its seals have been disturbed;

(g) fair wear and tear, including the natural ageing of seals, O-rings, lubricants and finishes, and cosmetic marks or scratches;

(h) vibration, recoil, mounting forces or impacts causing misalignment or loosening;

(i) loss, theft or damage in transit to us (see clause 12); or

(j) unlawful use, or export, re-export or transfer without authorisation (see clauses 15 and 17).

11.2 This warranty does not apply to:

(a) consignment, clearance, ex-demonstration or second-grade items, unless we state otherwise in writing at the time of sale;

(b) third-party accessories or parts not fitted by NoxWorks; or

12. Loss and theft

12.1 This warranty does not cover the loss or theft of a Device, or any damage arising from loss or theft. We recommend that you insure your Device.

12.2 If your Device is lost or stolen, you should report it to the police and obtain a crime reference number. You may also report it to us through our contact page or at [email protected], giving the Device serial number, the crime reference number and your Warranty Documentation. We will record the Device serial number as reported lost or stolen.

12.3 If a Device recorded as lost or stolen is presented to us for warranty, repair or service, we will:

(a) not provide warranty or other service for that Device;

(b) retain the Device where it is lawful to do so; and

12.4 A Device recorded as lost or stolen is excluded from this warranty until it is returned to the person who reported it, or until we are reasonably satisfied that it has been lawfully recovered or the report was made in error.

12.5 Anyone considering buying a used NoxWorks Device may contact us to check whether its serial number has been reported lost or stolen. We will only confirm whether a report exists and will not disclose any personal information.

13. Out-of-warranty service

13.1 Repairs, tube replacement, re-sealing, re-purging, collimation and servicing outside warranty are available at our standard rates. We will always provide a quotation before carrying out chargeable work.

14. Image intensifier tubes

Tube specification

14.1 The image intensifier tube fitted to your Device is recorded on your build certificate by serial number, together with its specification at the time of build. This specification includes, where available, figure of merit (FOM), signal-to-noise ratio (SNR), resolution, phosphor type and manufacturer's test data. This record is the Baseline Specification for warranty purposes.

Tube failure during the warranty period

14.2 A Tube Failure means that, during the one-year warranty period in clause 3 and under Normal Use, the tube:

(a) stops producing an image;

(b) produces an intermittent image, flickers or shuts down without cause;

(d) falls below the manufacturer's published minimum specification for that tube type.

14.3 If a Tube Failure is confirmed by our inspection, we will, at our option:

(a) re-pot the tube, meaning repair or replacement of the tube's integrated power supply and potting, and restore it to working order; or

(b) where re-potting is not possible, not economical, or would not restore the tube to its Baseline Specification, replace the tube with one of equal or better performance than the Baseline Specification.

14.4 A replacement tube will match the original phosphor type (green or white phosphor) where available. It may be from a different production batch or, where the original type is unavailable, from a different manufacturer, provided it meets or exceeds the Baseline Specification.

14.5 Re-potted or replacement tubes are warranted for the remainder of the original one-year warranty period.

14.6 We will test the tube against its Baseline Specification and the manufacturer's published data, and provide you with a written summary of our findings.

Normal tube characteristics (not defects)

14.7 The following are normal characteristics of image intensifier tubes and are not Tube Failures, provided they remain within the manufacturer's published specification:

(a) blemishes: small dark or bright spots present at the time of build, or developing over time, within the manufacturer's cosmetic specification;

(b) fixed-pattern noise: a faint honeycomb or chicken-wire pattern visible in bright conditions;

(d) halo: a glow around bright light sources;

(e) edge glow or shading at the edge of the image;

(f) equivalent background input (EBI): a faint background glow in total darkness; and

(g) gradual ageing: a gradual reduction in gain or brightness over the life of the tube.

Tube damage not covered

14.8 The following are not covered under any part of this warranty:

(a) burn damage: permanent bright or dark spots, lines or images burnt into the tube by exposure to light (see clauses 14.9 to 14.13);

(b) new blemishes caused by light exposure, impact or misuse, as opposed to those arising within specification under Normal Use;

(d) damage caused by incorrect batteries, incorrect voltage, reversed polarity or faulty external power sources;

(e) damage caused by lasers, including laser rangefinders, designators, aiming lasers and laser illuminators, whether direct or reflected;

(f) damage caused by the tube being removed, refitted or handled by anyone other than NoxWorks;

(g) operation with manual gain set inappropriately for the light conditions, where this causes damage; and

(h) any reduction in performance that remains within the manufacturer's published specification.

Light exposure

14.9 Image intensifier tubes amplify very small amounts of light. Exposure to daylight, bright artificial light or lasers can cause permanent and irreversible damage, including burn spots, burnt-in images and loss of performance.

14.10 Modern tubes include auto-gating and bright-source protection. These protect against brief exposure to bright light sources found in normal night-time use, such as passing vehicle headlights. They do not protect against:

(a) operating the Device in daylight or twilight with the objective lens uncovered;

(b) prolonged or repeated exposure to bright artificial light;

(d) lasers, whether direct or reflected; or

(e) storing or leaving the Device switched on with the objective lens uncovered in daylight.

14.11 To protect your tube, you should:

(a) always fit the objective lens cap, or a daylight or pinhole filter, when the Device is not in use or in lit conditions;

(b) only switch the Device on in darkness or low-light conditions;

(d) avoid looking at bright light sources through the Device; and

(e) follow the user manual at all times.

14.12 We will determine whether damage has been caused by light exposure through our inspection, including the pattern, location and nature of the damage. Burn damage typically appears as permanent spots or shapes matching the light source. We will act reasonably and provide a written explanation of our findings.

14.13 Damage found on inspection to be caused by excessive light exposure is excluded from every part of this warranty, including during the one-year warranty period. Where such damage has occurred, we can offer tube replacement or repair at our standard rates, and will provide a quotation before carrying out any work.

15. Lawful use

15.1 You are solely responsible for ensuring that your possession, use, carriage, storage, sale and transfer of the Device comply with all laws and regulations that apply to you. These include:

(a) firearms legislation and the conditions of any firearm or shotgun certificate, where the Device is used with or mounted on a firearm;

(b) wildlife, game and deer legislation, including restrictions on hunting or shooting at night;

(d) laws on trespass and access to land;

(e) road traffic, aviation and maritime laws, including restrictions on operating vehicles, aircraft or vessels using night vision; and

(f) export control, sanctions and import laws (see clause 17).

15.2 The Device must not be used for any unlawful purpose. NoxWorks accepts no responsibility or liability for any unlawful use of the Device, or for any loss, damage, injury, fine, penalty or legal action arising from it.

15.3 Any information or advice we give about the lawful use of the Device is general guidance only and is not legal advice. If you are unsure whether a particular use is lawful, you should seek independent legal advice or contact the relevant authority before using the Device.

15.4 We may refuse to sell, service or repair a Device, or decline a warranty claim, where we reasonably believe the Device has been or will be used unlawfully.

16. Safety, injury and liability

Safe use

16.1 Night vision devices restrict your field of view, depth perception, colour perception and peripheral vision. You must use the Device safely and in line with the user manual. In particular:

(a) do not operate a vehicle, aircraft, vessel or machinery using the Device unless you are trained, qualified and lawfully permitted to do so;

(b) take extra care when moving on foot, especially on uneven ground, near water, at height or near roads;

(d) do not rely on the Device as your only means of identifying people, animals or hazards, particularly before discharging a firearm; and

(e) ensure mounts, helmets and accessories are fitted correctly and securely.

16.2 The Device is a vision aid. It does not replace your own judgement, training or awareness of your surroundings, and you remain responsible for your actions while using it.

Injury and loss arising from use or misuse

16.3 Subject to clause 16.5, NoxWorks will not be liable for any injury, death, loss or damage arising from:

(a) misuse of the Device, or use contrary to the user manual or these terms;

(b) unlawful use of the Device (see clause 15);

(d) modification, repair or adjustment of the Device by anyone other than NoxWorks;

(e) use of the Device with incompatible, faulty or incorrectly fitted mounts, power sources or accessories; or

(f) any decision or action you take based on what you see, or fail to see, through the Device.

16.4 Subject to clause 16.5, if you are a consumer, we are only responsible for loss or damage you suffer that is a foreseeable result of our breaking these terms or failing to use reasonable care and skill. We are not responsible for business losses where the Device is used for private purposes.

What we do not exclude

16.5 Nothing in these terms limits or excludes our liability for:

(a) death or personal injury caused by our negligence or the negligence of our employees or agents;

(b) fraud or fraudulent misrepresentation;

(d) any other liability that cannot be limited or excluded under the law of England and Wales.

17. Export controls and unauthorised export

17.1 The Device and its Components, including the image intensifier tube, are controlled goods under UK strategic export controls, including the Export Control Order 2008. Some Components may also be subject to the export control laws of other countries, including United States re-export controls.

17.2 You must not export, re-export, transfer, ship, carry or send the Device or any of its Components out of the United Kingdom, whether by sale, gift, loan, or personal carriage when travelling, unless:

(a) any required export licence or other authorisation has been obtained from the Export Control Joint Unit (ECJU) or other relevant authority; and

(b) the export complies with all applicable sanctions, embargoes and import laws of the destination country.

17.3 Exporting controlled goods without the required authorisation may be a criminal offence under UK law, including the Customs and Excise Management Act 1979, and may result in seizure of the goods, fines or imprisonment.

17.4 If you export or attempt to export the Device or any Component without the required authorisation:

(a) this warranty becomes void for that Device, and we will not provide any warranty, repair or service for it;

(b) NoxWorks accepts no liability for any loss, damage, penalty, seizure or legal action arising from the export; and

(c) we may report the matter to the relevant authorities, including the ECJU and HM Revenue & Customs, and will co-operate fully with any investigation.

17.5 We may refuse to sell, transfer or service any Device, and may refuse to recognise any change of ownership under clause 8, where we reasonably suspect that the Device may be exported without authorisation, diverted to an unauthorised end user or used in breach of sanctions.

17.6 If you are a business customer, you will indemnify NoxWorks against any loss, liability, fine, cost or expense (including reasonable legal costs) that NoxWorks suffers as a result of your export, re-export or transfer of the Device in breach of this clause 17.

18. Your personal data

18.1 We use the personal information provided to us in warranty claims and loss or theft reports, including details shown in the Transfer Log, only to administer this warranty, keep records of Device service and reported losses or thefts, and meet our legal obligations, including export control record-keeping.

18.2 Where a Device is recorded as lost or stolen, or where we suspect a breach of export control law, we may share relevant information with the police or other relevant authorities for the prevention or detection of crime.

18.3 We handle personal information in line with UK data protection law and our privacy policy.

19. Your statutory rights

19.1 If you are a consumer, you have legal rights under the Consumer Rights Act 2015 if goods are faulty, not as described, or not of satisfactory quality. These rights are separate from this warranty. Nothing in these terms, including the conditions on transfer and documentation, limits or excludes them. Advice about your legal rights is available from Citizens Advice.

19.2 Nothing in these terms limits or excludes our liability for death or personal injury caused by our negligence, for fraud or fraudulent misrepresentation, or for any other liability that cannot be limited or excluded by law.

20. Business customers

20.1 If you buy the Device in the course of a business, including on behalf of a police force, government body or other organisation, the remedies in clauses 6 and 14 are your sole remedies under this warranty, to the extent permitted by law.

20.2 We will not be liable to business customers for any indirect or consequential loss, or for loss of profit, revenue, contracts or business arising from a Defect.

20.3 Separate warranty or service terms may be agreed in writing for contract and agency sales. Where they are, those terms take priority over these.

21. Complaints

21.1 If you are unhappy with how a claim has been handled, please contact us at [email protected]. We will acknowledge your complaint within 5 working days and aim to resolve it within 28 days.

22. General

22.1 If any provision of these terms is found to be invalid or unenforceable, the remaining provisions will continue in full force and effect.

22.2 We may update these terms from time to time. The terms in force on the Purchase Date apply to your Device.
