We operate mobile Diesel Particulate Filter (DPF) cleaning, engine carbon cleaning, diagnostics and ECU Remapping service across the UK and provide information and booking services via www.engiclean.co.uk (the “Site”).
2. Scope of These Terms
These Terms & Conditions (the “Terms”) govern:
- your use of the Site (including any sub-domains);
- enquiries, quotations and bookings made by telephone, web form or instant messaging; and
- our provision of services to consumers and business customers.
If you order goods (e.g., additives) from us, additional sales terms may apply. If there is any conflict, a written Services Agreement or Work Order signed by both parties will prevail.
3. Key Definitions
Services means our mobile or on-site diagnostics, DPF cleaning (on-vehicle), engine carbon cleaning, forced regenerations and related advisory work.
Customer/you means the person or business placing a booking.
Work Order means the booking confirmation detailing the vehicle, location, estimated price and any special instructions.
Warranty Period means 28 days from completion of a DPF clean unless stated otherwise in writing.
4. Placing a Booking
4.1 You can request a booking online, by phone or by message. We will confirm availability and send a Work Order. A binding contract is formed when you accept the Work Order (including by replying “yes”, paying a deposit, or allowing us to start work).
4.2 You must be 18+ and authorised to permit work on the vehicle.
4.3 We may refuse a booking if, in our professional opinion, work would be unsafe, unlawful or unlikely to succeed without prior repairs.
5. Pre-Work Checks & Customer Responsibilities
5.1 You agree to:
- provide accurate vehicle details, fault history and any modifications;
- ensure the vehicle is roadworthy, has sufficient fuel/AdBlue and a charged battery;
- provide a safe, legal working area (off the public highway where possible), with permission for us to attend; and
5.2 We will carry out reasonable pre-work checks (including a fault code scan and, where applicable, live-data review). These checks are not a substitute for a full mechanical inspection. Hidden or latent faults can remain undetectable until load or temperature changes occur during/after cleaning or regeneration.
5.3 Where underlying mechanical, electrical or control faults are present (e.g., failed EGR, injector issues, boost leaks, faulty pressure/temperature sensors, failing turbo/actuator, coolant or oil contamination), cleaning may not resolve the symptoms. We may recommend further diagnostics or repairs before or after cleaning. You are responsible for those costs.
6. The Cleaning Process & Important Risks
6.1 DPF cleaning limitations. DPF cleaning removes soot. It does not remove all ash or rectify breakages, internal collapse, melted cores, severe oil contamination or cracks. Severely compromised DPFs, blocked catalysts or SCR systems may require removal and specialist off-car cleaning or replacement.
6.2 Engine carbon cleaning. Where hydrogen-assisted or chemical carbon cleaning is performed, the process alters combustion conditions for a short period. While generally safe when performed correctly, pre-existing weaknesses (e.g., stuck EGR valves, sticky turbo vanes, degraded hoses, carbon-fragility) can surface. Manufacturer warranties may be affected by modifications or third-party cleaning processes — you should check your vehicle warranty.
6.3 Forced regeneration. Regeneration elevates exhaust gas temperatures. If sensors, injectors, vapourisers or the DPF substrate are compromised, heat can exacerbate existing defects.
6.4 Runaway/over-rev risk. In rare cases, oil ingestion or uncontrolled combustion may cause an engine runaway. If safe to do so, we will follow emergency shutdown procedures. You must follow our instructions immediately if present at the vehicle.
6.5 No guarantee of outcome. We will exercise reasonable skill and care, but we cannot guarantee a permanent solution where underlying faults, driving style or usage patterns (e.g., repeated short trips) contribute to DPF loading.
7. Prices, Call-Outs & Payment
7.1 Guide prices are shown on the Site and in marketing. Final pricing depends on vehicle, location, time on site, diagnostics and consumables. Parking, tolls and congestion charges may be added at cost.
7.2 A call-out/diagnostics fee may apply if work cannot proceed due to unsafe conditions, inaccurate information, or undisclosed faults that prevent cleaning/regeneration.
7.3 Unless agreed otherwise, payment is due on completion by card, bank transfer, or approved finance. We may require an upfront deposit for longer jobs or parts procurement.
8. Payment Assist & Finance Options
8.1 Where offered, we may provide access to third-party finance providers (e.g., Payment Assist) for spreading the cost. Approval is subject to the finance provider’s terms, affordability checks and your credit status.
8.2 Finance is a separate agreement between you and the provider. If finance is declined or cancelled, our service charges remain payable in full.
9. Cancellations, Rescheduling & Cooling-Off
9.1 Consumer (off-premises/Distance) bookings. If you are a consumer, you have a statutory 14-day cooling-off period under the Consumer Contracts Regulations 2013. However, where you ask us to visit and begin services within that period, you acknowledge that your right to cancel may be lost once the services are fully performed, and you must pay for work carried out up to cancellation.
9.2 Rescheduling. Please give at least 24 hours’ notice to reschedule. Short-notice changes may incur a reasonable charge to cover lost time and travel.
9.3 No-shows/inaccessibility. If we attend and cannot gain access, or the vehicle is unavailable or unsafe, a call-out fee and travel costs may be charged.
10. Warranties & Re-Clean Policy
10.1 For standard on-vehicle DPF cleaning, we provide a 28-day limited warranty from completion against immediate re-blockage due solely to cleaning workmanship.
10.2 The warranty is void where re-blockage is caused by underlying faults, oil or coolant contamination, failed sensors/injectors, unsuitable driving cycles, tampering or software modifications.
10.3 Remedies are limited to a re-assessment and, if appropriate, one re-clean during the Warranty Period. We do not cover consequential losses, recovery, hire cars or time off work.
10.4 Any manufacturer’s warranties for parts supplied will pass to you. We give no additional warranty on third-party parts.
11. Data, Reports & Photos
11.1 We may record diagnostic data, pre/post readings, photographs or short videos for reporting, training and quality assurance.
11.2 We will handle personal data in line with our Privacy & Cookie Policy. You can request a copy of your records by contacting us.
11.3 You grant us a non-exclusive licence to anonymise and use technical data (not your personal data) for service improvement and statistics.
12. Liability
12.1 Nothing in these Terms limits liability for death or personal injury caused by negligence, fraud, or any rights you have under the Consumer Rights Act 2015.
12.2 Subject to 12.1, we are not liable for: (a) pre-existing faults or wear; (b) failures that arise during or after cleaning due to latent defects; (c) loss of profit, business interruption, or indirect/consequential loss; or (d) incompatibility with aftermarket modifications or prior ECU mapping.
12.3 Our total liability for any single claim relating to the Services is limited to the price paid for those Services.
13. Timeframes & Delays
13.1 Estimated arrival and completion times are guides only. Traffic, parts availability and diagnostic complexity can affect duration.
13.2 If delays occur, we will keep you informed and rearrange where necessary. We are not liable for delays caused by events outside our reasonable control.
14. Service Areas & Access
14.1 We cover specified UK postcodes. Surcharges may apply for remote areas, toll zones or out-of-hours work.
14.2 You are responsible for local permissions, parking and access. We may decline roadside work if unsafe or prohibited.
15. Anti-Tamper & Compliance
15.1 We do not remove, gut or illegally modify DPFs or emissions systems. We may decline service where a vehicle has illegal emissions modifications.
15.2 You are responsible for ensuring your vehicle remains compliant with road traffic and environmental laws.
16. Complaints
If you are unhappy, please contact us first at info@engiclean.co.uk. We will investigate and aim to resolve quickly. If we cannot resolve a consumer complaint, you may be able to use Alternative Dispute Resolution (ADR). Details available on request.
17. Website Use
17.1 Content on the Site is provided for general information. We try to keep it accurate but it may not always reflect the latest diagnostics guidance.
17.2 You must not misuse the Site or attempt to gain unauthorised access.
17.3 All logos, trademarks and content are owned by us or our licensors. You may not copy or reuse content without permission.
18. Privacy & Cookies

20. Governing Law & Jurisdiction
If you are a consumer resident in the UK, mandatory consumer protection laws of your jurisdiction apply. Otherwise, these Terms and any dispute or claim (non-contractual or contractual) shall be governed by the laws of Scotland if our registered office is in Scotland (or England & Wales if registered there). Courts of that jurisdiction shall have exclusive jurisdiction, save that consumers may bring claims in their local courts.
