Clear terms, fair conditions, and your responsibilities as a customer.
The following components are covered under our 12-month unlimited mileage warranty for engine rebuild and reconditioning work:
The crankshaft and engine block must be in serviceable condition for the standard warranty to apply. If these components require replacement or significant repair beyond standard reconditioning, costs may increase significantly. We will always quote separately and obtain your approval before proceeding with any additional work.
Labour is fully covered for any failure attributable to our workmanship or supplied parts within the warranty period. This includes diagnosis, removal, re-repair, and refitting at our Billericay workshop.
To avoid disputes, please note the following exclusions. These items are either ancillary components not part of the engine rebuild, or issues caused by factors outside our control.
These components are often removed during engine work but are not part of the reconditioning process. Their serviceability and lifespan are not guaranteed under the engine warranty.
We will advise you if any of these components are found to be unserviceable during strip-down and will quote separately for replacement.
To protect both parties and ensure your warranty remains valid, please adhere to the following requirements.
You must remove all personal belongings before handing over the vehicle. This includes chargers, cables, dashboard decorations, children's car seats, boosters, loose change, sunglasses, and air fresheners. We are not responsible for lost or missing items left in the vehicle.
Strongly advised: photograph bodywork, paintwork, wheels, tyres, bumpers, and any existing dents or scratches before collection or recovery. Without dated proof, we cannot accept claims of new damage allegedly occurring while in our care. Recovery services may cause transit damage — photos protect both parties.
After an engine rebuild, the engine is like new and requires a mandatory service at 2,000 miles (± 200 miles tolerance). This service MUST be carried out by JLR Engine Specialists. It is not free and not part of the warranty. Failure to complete this service voids the warranty entirely.
Do not take your vehicle to any other mechanic or garage for engine-related work during the warranty period. Any third-party interference immediately voids the warranty. We cannot guarantee work done by others, and such interference may cause damage not attributable to our original rebuild.
ECU remapping, LPG conversions, performance upgrades, or fitting non-standard parts immediately void the warranty. The engine was rebuilt to OEM specification; altering calibration or components places stress beyond validated tolerances.
The following actions will immediately invalidate your warranty coverage. Please read carefully.
The warranty is non-transferable. It applies only to the original customer who paid for the work. If the vehicle is sold, transferred, or ownership changes in any way, the warranty is immediately voided. We cannot guarantee how subsequent owners will maintain or treat the vehicle.
Failure to have the 2,000-mile service (± 200 miles) carried out by JLR Engine Specialists voids the warranty. This service is critical for verifying bedding-in and catching early issues. It is chargeable and must be booked proactively.
Any engine-related work performed by another garage, mobile mechanic, or unauthorised person during the warranty period voids coverage immediately. This includes diagnostics, adjustments, or repairs.
ECU remapping, LPG conversion, performance tuning, aftermarket turbo upgrades, or any non-OEM specification parts void the warranty. The engine was built to factory tolerances; modifications exceed validated limits.
Running with low oil/coolant, ignoring warning lights, overheating, racing, track days, towing beyond rated capacity, or commercial hire use voids the warranty. Regular maintenance per manufacturer intervals remains your responsibility.
If you believe you have a warranty issue, follow this process. We aim to respond to all claims within 2 business days.
Call 0203 488 4649 or email warranty@jlrengines.co.uk within 14 days of noticing any issue. Do not continue driving if the fault is severe.
Invoice number, vehicle registration, current mileage, and clear description of the issue. Photos/videos of symptoms help speed assessment.
We arrange inspection at our Billericay workshop. Collection may be available depending on the issue. Do not allow third-party diagnosis.
If covered, we rectify at our cost. If not covered, we provide a detailed explanation and separate quote. Decision communicated in writing.
Engine rebuilds are complex technical procedures. We provide estimated completion dates based on current information and typical turnaround times. Unexpected issues (e.g., cracked cylinder head, damaged crankshaft requiring replacement, parts availability delays) may extend the repair time. We are not liable for inconvenience caused by reasonable delays. We will keep you informed throughout the process and update you promptly if timelines change.
Direct answers to common warranty questions. If yours isn't answered here, call us.
No. The warranty is strictly non-transferable and applies only to the original customer who paid for the work. If the vehicle is sold, transferred, or ownership changes in any way, the warranty is immediately voided. We cannot verify how subsequent owners maintain or treat the vehicle.
Your warranty becomes void. The 2,000-mile service (± 200 miles tolerance) is mandatory and must be carried out by JLR Engine Specialists. It verifies the engine is bedding in correctly and catches early issues. This service is chargeable and not included in the rebuild price. Book it proactively to maintain your cover.
No. Any engine-related work performed by another garage, mobile mechanic, or unauthorised person during the warranty period voids coverage immediately. This includes diagnostics, adjustments, or repairs. We cannot guarantee work done by others, and such interference may cause damage not attributable to our original rebuild. Contact us first for any concerns.
All personal belongings: chargers, cables, dashboard decorations, children's car seats, boosters, loose change, sunglasses, air fresheners, and any item not screwed down or part of the original vehicle. We advise this over the phone and in the quotation form. We are not responsible for lost or missing items left in the vehicle.
Strongly advised. Photograph bodywork, paintwork, wheels, tyres, bumpers, and any existing dents or scratches before collection or recovery. Without dated proof, we cannot accept claims of new damage (scuffs, dents, scratches) allegedly occurring while the vehicle was in our care. Recovery services may cause transit damage — photos protect both parties.
No. Turbochargers are classified as ancillary components and are not covered under the engine rebuild warranty, even if removed during the work. The same applies to fuel injectors, alternators, AC pumps, starters, DPFs, EGR valves, and suspension components. We will advise if any are unserviceable and quote separately for replacement.
The standard warranty assumes the crankshaft and engine block are in serviceable condition. If these require replacement or significant repair beyond standard reconditioning, costs may increase significantly. We will always quote separately and obtain your written approval before proceeding. Replacement blocks/cranks carry their own warranty terms, confirmed at time of quote.
Typically 2–4 weeks from drop-off to collection, depending on parts availability and machine shop turnaround. Complex builds or unexpected issues (cracked heads, damaged components) may extend this. We provide estimated dates but are not liable for inconvenience caused by reasonable delays. You will be kept informed throughout.
Courtesy vehicles are subject to availability and cannot be guaranteed. Contact us at booking to discuss options. We recommend arranging alternative transport as backup, especially for longer rebuild jobs where delays are possible.
Take dated photos of your vehicle before collection. If transit damage occurs, these photos are essential evidence for insurance claims against the recovery provider. We will assist with documentation but are not liable for third-party transit damage. Our responsibility begins when the vehicle is physically received at our workshop and signed in.
No. The warranty covers only the specific components listed in "What IS Covered" and labour directly related to their failure. Consequential damage to non-covered components (e.g., turbo failure caused by oil starvation from a covered bearing failure) is excluded. We will always explain coverage clearly during claim assessment.
Nothing in this warranty excludes or restricts your statutory rights under the Consumer Rights Act 2015. Services must be carried out with reasonable care and skill. If work is unsatisfactory, you may be entitled to repeat performance or a price reduction. Full contractual terms are published at /terms-and-conditions/. For independent advice, contact Citizens Advice Consumer Service on 0808 223 1133.
Call us to discuss your cover before booking. We're happy to clarify any terms, explain component coverage, or walk through the 2,000-mile service requirement. Transparency is central to how we operate — no hidden clauses, no surprises.
