These Terms and Conditions apply to retail / consumer customers of Krypton Tune Ltd.

1. Definitions

“Company”, “we”, “us”, “our” means Krypton Tune Ltd.
“Customer”, “you”, “your” means the retail customer, consumer, vehicle owner, or authorised user of the vehicle.
“Vehicle” means the motor vehicle, van, or other vehicle presented to us for inspection, servicing, diagnosis, repair, tyre fitting, calibration, programming, MOT-related work, or other services.
“Services” means all labour, diagnostic work, inspection, servicing, repairs, fitting, testing, calibration, programming, and related work carried out by us.
“Parts” means any parts, components, consumables, fluids, accessories, or materials supplied or fitted by us.

2. Basis of Contract and Acceptance

2.1 These Terms and Conditions apply to all Services supplied by us unless otherwise agreed in writing.

2.2 By booking work, requesting an estimate, signing a job card, approving an estimate, authorising work verbally, by email, by text, by electronic means, or by leaving a Vehicle with us for inspection or repair, you agree that the Services will be supplied on these Terms and Conditions.

2.4 Where a Vehicle is delivered to us by another person on your behalf, including a recovery operator, fleet representative, family member, or friend, you remain responsible for ensuring that the person delivering the Vehicle has authority to instruct us on your behalf.

2.5 Nothing in these Terms and Conditions affects your statutory rights.

3. Estimates and Authorisation

3.1 Any estimate or quotation we provide is based on the information available at the time and any preliminary inspection carried out. Unless expressly stated in writing, estimates are not fixed-price quotations.

3.2 Additional faults, defects, or required work may become apparent once inspection, dismantling, testing, or repair work has started. Where this happens, we will seek your approval before carrying out additional chargeable work whenever reasonably practicable.

3.3 If we cannot contact you after making reasonable attempts, we may carry out only such additional work as is reasonably necessary to:

• prevent an immediate safety risk; 
• prevent the Vehicle from suffering further material damage; or 
• make the Vehicle safe or lawful to move or secure. 

3.4 Where possible, any such work will be limited to the minimum reasonably necessary in the circumstances, and we will explain the reasons for that work to you as soon as reasonably practicable.

3.5 You acknowledge that diagnostic and investigative work is a chargeable professional service, whether or not you choose to proceed with any resulting repair recommendations.

3.6 Modern vehicles are complex and faults may be caused by multiple or interconnected systems. Identifying one fault does not guarantee that further faults, warning lights, or issues will not later become apparent.

3.7 Where additional diagnostic time is required beyond any initial estimate, we will inform you where reasonably practicable before proceeding.

4. Prices and Payment

4.1 Unless stated otherwise, all retail prices shown by us are inclusive of VAT.

4.2 Payment is due immediately upon completion of the Services unless we have agreed otherwise in writing.

4.3 We may accept payment by cash, card, bank transfer, finance provider, or any other payment methods displayed or agreed by us.

4.4 We reserve the right, where lawful, to retain possession of the Vehicle until all outstanding charges relating to the Vehicle have been paid in full.

4.5 If payment is not made when due, we may refuse to release the Vehicle until the outstanding balance has been settled.

5. Parts

5.2 Unless otherwise agreed in writing, we may supply original equipment, OEM-equivalent, aftermarket, or other suitable replacement parts.

5.3 Parts will be selected and fitted using reasonable care and skill and, where applicable, in accordance with manufacturer recommendations or recognised industry practice.

5.4 Any removed old parts may be disposed of unless you request their return before or at the time of authorising the work.

5.5 Used, Recycled, Refurbished or Reconditioned Parts

5.5.1 Where new Parts are unavailable, on extended backorder, uneconomic, or where you specifically request a lower-cost repair option, we may offer to supply used, recycled, refurbished, or reconditioned Parts from third-party suppliers.

5.5.2 Where such Parts are supplied:

• we will, where reasonably practicable, inform you in advance and obtain your approval before fitting them; 
• any warranty on the Part itself will be limited to any warranty offered by the supplier, if any; 
• we do not guarantee the future longevity, durability, or performance of such Parts beyond confirming that they appeared suitable for installation at the time of fitting; and 
• we warrant only that we will use reasonable care and skill in selecting and installing the Part. 

5.5.3 Nothing in this clause excludes liability for loss or damage caused by our negligence or failure to use reasonable care and skill.

5.6 Customer-Supplied Parts

5.6.1 We do not normally fit Parts supplied by customers. If, at our sole discretion, we agree to fit a customer-supplied Part:

• we do not give any warranty as to the quality, suitability, legality, compatibility, or durability of that Part; 
• we are only responsible for using reasonable care and skill in carrying out the installation; 
• if the Part is defective, incorrect, incompatible, unsafe, or otherwise unsuitable, any additional labour, diagnostic time, removal, or refitting work may be chargeable; and 
• we reserve the right to refuse to fit any Part we reasonably believe to be unsafe, counterfeit, unsuitable, unlawfully modified, or incompatible with the Vehicle. 

5.6.2 Nothing in this clause excludes liability for death or personal injury caused by negligence, fraud, or any other liability which cannot lawfully be excluded or restricted.

6. Servicing and Repairs

6.1 We will carry out Services using reasonable care and skill.

6.2 Replacement Parts may be original equipment, equivalent quality, aftermarket, or other suitable replacement parts unless otherwise agreed in writing.

6.3 Due to age, corrosion, wear, prior repairs, or prior damage, some components may be seized, heavily corroded, fragile, or difficult to remove.

6.4 During dismantling or removal, bolts, nuts, studs, fixings, sensors, pipes, trim, fasteners, clips, or other components may break, seize, strip, or become damaged where this is reasonably attributable to the Vehicle’s age, corrosion, prior repairs, deterioration, or condition.

6.5 Where this occurs, additional labour and/or replacement Parts may be required to complete the work safely and correctly. We will inform you where reasonably practicable before carrying out additional chargeable work.

6.6 We are not responsible for faults, warning lights, failures, or issues which were pre-existing, unrelated to our work, or which become apparent only because the original fault has been investigated or repaired.

6.7 If, during diagnosis or repair, the Vehicle becomes immobile or unsafe to drive due to its condition, pre-existing faults, or necessary dismantling, we may arrange recovery, storage, or transport at your expense where reasonably necessary.

7. Wheel Fixings and Tyre Installation

7.1 Where wheels or tyres are removed, replaced, or refitted by us, wheel fixings will be tightened using appropriate tools and procedures in accordance with standard industry practice.

7.2 Wheel fixings may settle after installation as part of normal bedding-in. For that reason, you are advised to check and, if necessary, have wheel fixings re-torqued after approximately 50 miles (80 kilometres) of driving following tyre replacement or wheel removal.

7.3 We are not liable for loss or damage arising from failure to carry out the recommended re-check where this advice has been given.

7.4 Where requested, we may carry out a complimentary torque check after tyre installation, subject to workshop availability.

8. Customer Responsibilities

8.1 You confirm that you are the legal owner of the Vehicle or are otherwise authorised to instruct us in relation to it.

8.2 You must tell us about any known faults, warning lights, modifications, prior accident damage, prior repairs, unusual behaviour, software changes, security issues, or other information that may affect diagnosis, repair, safety, or legality.

8.3 Personal items should be removed from the Vehicle before work starts. We are not responsible for loss of or damage to personal belongings left in the Vehicle unless caused by our negligence.

8.4 For privacy, confidentiality, security, and health and safety reasons, you must disable, unplug, or remove in-vehicle audio and video recording devices before the Vehicle enters the workshop. If such devices remain active, we may ask for them to be disabled before work starts and may refuse or delay the work if this is not done.

8.5 You must ensure the Vehicle contains sufficient fuel for reasonable diagnostic procedures and road testing unless otherwise agreed. If additional fuel is required, we may add fuel at your expense.

8.6 Where the Vehicle is in unusually poor condition, excessively dirty, unsafe, heavily modified, contaminated, or otherwise unsuitable for normal inspection or repair, we may delay, refuse, or limit the work until it is safe and reasonably practicable to proceed.

8.7 If you request only a minimal, temporary, or budget repair, you acknowledge that such repair may not fully resolve all underlying faults or provide a long-term solution.

9. Road Testing and Vehicle Operation

9.1 You authorise us to operate and road test the Vehicle where reasonably necessary for diagnosis, repair verification, calibration, quality control, or confirmation of fault rectification.

9.2 Road testing may include driving the Vehicle under a range of ordinary road conditions reasonably required to identify or verify faults, including braking, acceleration, deceleration, transmission, steering, suspension, driveline, and motorway-speed testing where appropriate.

9.3 All road testing will be carried out by authorised personnel acting with reasonable care and professional judgment.

9.4 If the Vehicle is considered unsafe, unroadworthy, uninsured for road use where relevant, or otherwise unsuitable for public-road testing, we may restrict testing to private land, workshop-based procedures, or decline testing altogether.

9.5 A reasonable increase in mileage may occur during diagnosis, calibration, adaptation procedures, or repair verification.

9.6 Modern vehicles may record fault codes, driving data, calibration data, or system logs during testing, diagnosis, programming, or operation. You acknowledge that such data may be generated as part of normal workshop procedures.

9.7 We are not responsible for faults or issues arising during road testing where those faults are caused by the Vehicle’s pre-existing condition, hidden defects, or factors outside our control.

10. Appointment Times and Delays

10.1 Booking dates, appointment times, and completion times are estimates only unless expressly agreed otherwise in writing.

10.2 Delays may arise due to diagnosis complexity, seized components, hidden faults, manufacturer technical procedures, software restrictions, parts availability, weather, subcontractor delays, or other circumstances outside our reasonable control.

10.3 We will not be liable for reasonable delays arising from such matters.

11. ADAS Calibration and Driver Assistance Systems

11.1 Where Services involve inspection, adjustment, calibration, or verification of Advanced Driver Assistance Systems (ADAS), we will use reasonable care and skill together with appropriate equipment and procedures available to us.

11.2 You acknowledge that correct operation of ADAS systems may depend on matters outside our control, including vehicle condition, prior accident damage, suspension geometry, wheel alignment, tyre condition, tyre size, ride height, software status, prior repairs, and the quality or type of replacement components fitted to the Vehicle.

11.3 We are not responsible for ADAS warnings, malfunctions, system limitations, or recalibration requirements arising from pre-existing issues, hidden damage, manufacturer restrictions, or subsequent work carried out by others.

12. Battery Voltage, Programming and Electronic Systems

12.1 Many modern diagnostic, coding, programming, and software procedures require stable battery voltage and uninterrupted communication with vehicle control modules. We will use reasonable care and skill and appropriate support equipment where reasonably required.

12.2 We are not responsible for faults, interruption, corruption, or module failures arising from:

• weak, defective, or failing batteries; 
• battery management system restrictions; 
• pre-existing electrical faults; 
• manufacturer software faults or restrictions; 
• communication failure outside our control; or 
• hidden defects within the Vehicle’s electronic systems. 

12.3 If the Vehicle’s condition prevents safe or reliable programming or diagnostic procedures, we may suspend or decline the work until the underlying issue has been addressed.

13. Vehicle Software, Programming and Modified Vehicles

13.1 Where we carry out ECU programming, coding, adaptation, configuration, software changes, or similar work, we will do so using reasonable care and skill and with professional equipment or recognised industry-standard processes where appropriate.

13.2 You acknowledge that vehicle performance, reliability, and component lifespan may be affected by many factors outside our control, including age, mileage, maintenance history, fuel quality, driving style, wear, pre-existing faults, previous modifications, and prior software changes.

13.3 We are not responsible for failures, wear, or consequential issues caused by the Vehicle’s pre-existing condition, hidden faults, previous poor repairs, undisclosed modifications, or factors unrelated to the work we carried out.

13.4 Vehicles modified from manufacturer specification may require additional labour, specialist procedures, or further diagnosis, and we cannot guarantee compatibility of manufacturer procedures, software, or diagnostic equipment with modified vehicles.

13.5 Where manufacturer updates, dealer updates, over-the-air updates, or subsequent third-party work alter, overwrite, or interfere with settings, calibrations, coding, or programming previously carried out by us, any re-checking or re-programming may be chargeable.

14. Vehicle Emissions Systems and Illegal Modifications

14.1 We will not carry out, supply, install, or facilitate modifications to disable, remove, bypass, defeat, or circumvent emissions-control systems where doing so would make the Vehicle unlawful for road use.

14.2 This includes, without limitation:

• DPF removal or bypass; 
• EGR removal or bypass; 
• SCR / AdBlue removal or bypass; 
• catalytic converter removal; and 
• software or devices intended to suppress emissions-related faults or defeat emissions controls. 

14.3 Where a Vehicle has existing unlawful or questionable emissions-related modifications, we reserve the right to refuse work where such modifications may affect legality, safety, diagnosis, or operation.

14.4 We are not responsible for faults, warning lights, legal issues, or performance issues arising from unlawful or non-compliant emissions-related modifications previously carried out by others.

15. Diagnostics, Technical Access and Cybersecurity

15.1 Modern vehicles contain complex electronic systems, security systems, gateways, manufacturer access controls, and software protections. Diagnostic and programming procedures may require access to manufacturer systems, security gateways, third-party technical platforms, or authorised security approval routes.

15.2 We may access Vehicle systems, control units, software interfaces, and technical data where reasonably necessary to diagnose faults, verify repairs, carry out calibration, or complete authorised work.

15.3 Certain functions may be restricted by manufacturer security protections, access rules, subscriptions, system permissions, cybersecurity restrictions, or authentication requirements. Where such restrictions limit or prevent completion of the requested work, we will not be responsible for any resulting inability to complete that work.

15.4 Fault-finding is an investigative process. The identification or rectification of one fault does not guarantee that no further faults, related issues, or warning messages will exist or appear later.

15.5 Where further faults are discovered, we may provide additional recommendations or estimates for further diagnostic work or repair.

16. Warranties and Guarantees

16.1 We warrant that Services supplied by us will be carried out using reasonable care and skill.

16.2 Unless otherwise agreed in writing, our labour warranty is 12 months or 12,000 miles, whichever occurs first, from completion of the relevant work.
