These terms and conditions set out the basis on which Delta Engines Ltd (“Delta Engines”, “we”, “us”, “our”) supplies goods and services to you (“the customer”, “you”, “your”). They apply to all engine supply, reconditioning, fitting, diagnostic and related work we carry out, and to all goods we supply.
Delta Engines Ltd is a company registered in England and Wales under company number 12702487. Our registered address and workshop is Unit 15D Askew Farm Lane, Grays, Essex RM17 5XR. You can contact us on 02033 180532 or 07902 539094, by WhatsApp on +44 7936 418074, or at support@deltaenginesltd.co.uk.
Nothing in these terms affects your statutory rights as a consumer, including your rights under the Consumer Rights Act 2015.
1. These terms and how a contract is formed
1.1 These terms are the only terms of the contract between us. Any change to them must be agreed in writing by a director of Delta Engines Ltd.
1.2 A contract is formed when we accept your instruction to proceed — whether given in writing, by email, by phone, through our website, or by delivering your vehicle to us for agreed work — or when we begin the work, whichever happens first.
1.3 If we ever need to correct an obvious typographical or clerical error in a quote or invoice, we will tell you before proceeding and you may cancel without charge if the correction materially changes the price.
1.4 Insurance-funded work. Where work is carried out on the authority of your insurer, the insurer is treated as the customer for the purposes of instruction and payment. However, you remain responsible for any excess and for any part of the price your insurer does not pay.
2. Quotes and estimates
2.1 A quote for engine work is a considered estimate of the likely cost, prepared without dismantling your engine for detailed inspection. It is valid for 30 days from the date given.
2.2 Once your engine is stripped and inspected, we may find additional faults or unserviceable components that could not reasonably have been identified beforehand. If so, we will stop work, explain what we have found, and give you a revised price. We will not carry out additional chargeable work without your express approval.
2.3 If you decline additional work that is essential for the engine to run correctly, you may collect your vehicle in its current state. You will only be charged for work actually done and parts actually supplied to that point. Our labour rates are £125 per hour for specialist engine work and £75 per hour for general work, with VAT included.
2.4 Quotes are prepared from the information you give us — including the vehicle registration you enter into our lookup tool and your description of the fault. Please check that this information is accurate and complete. If the vehicle, its specification or its condition turns out to be materially different from what we were told, we may need to revise the price, and we will always tell you before proceeding.
3. What our reconditioning covers
3.1 Unless your quote states otherwise, a reconditioned engine is supplied as a bare assembly: cylinder block, cylinder head(s) and sump, rebuilt with the following as standard — pressure-tested cylinder head(s), refaced valves and seats, new valve stem seals, new head gasket(s), new piston rings, new main and big-end bearings, inspected or reground crankshaft, new oil pump, and a new timing belt or chain kit.
3.2 Your original ancillaries (turbocharger, injectors, starter, alternator, manifolds, sensors, pumps and similar) are refitted to the rebuilt engine unless we agree otherwise. These are your existing parts: we will tell you during our health check if any are worn or unserviceable, and give you an itemised list of essential and advisory replacements to approve or decline before we fit them.
4. Exchange engines and surcharges
4.1 Engines supplied on an exchange basis require your old unit in return. Any surcharge taken is refunded in full within 7 working days of us receiving your old unit, provided it is complete, assembled, and serviceable as a core — meaning no hole in the block and no spun main bearings that have damaged the block beyond repair.
4.2 If your old unit arrives incomplete, disassembled or unserviceable as a core, we will contact you with the evidence and the applicable deduction before withholding any part of the surcharge.
5. Price and payment
5.1 All prices are quoted in pounds sterling. Delta Engines Ltd is VAT registered (VAT number GB 502 3788 04), and all prices are quoted inclusive of VAT — the price we quote is the price you pay.
5.2 Payment is due in full on completion of the work, before the vehicle is collected or delivered. We accept debit cards, bank transfer and cash; credit cards are accepted at our discretion. You can pay up to £1,000 of any invoice by card (a deposit, for example) — any balance above £1,000 is payable by bank transfer, and we will provide our account details with your invoice. Bank transfer and cash are welcome for any amount. We never charge extra for paying by card.
5.3 We may charge statutory interest on overdue amounts in accordance with the Late Payment of Commercial Debts (Interest) Act 1998 (business customers) or at 4% above the Bank of England base rate (consumers).
5.4 We hold a lien over your vehicle and any goods supplied until all sums due have been paid in full and cleared.
5.5 Deposits. Where an engine or parts must be specially ordered for your job, we may ask for a deposit before ordering, and we will tell you the amount when we quote. If you cancel after we have placed the order, we may retain from the deposit only the costs we have reasonably and unavoidably incurred (such as non-returnable parts or supplier restocking charges), and we will refund the balance. Your cancellation rights in section 9 are unaffected.
5.6 Ownership of goods. Ownership of any engine or parts we supply passes to you only when we have received payment in full and cleared. Until then, risk in the goods passes to you on delivery or fitting, but the goods remain our property.
6. Timescales
6.1 Completion dates are given in good faith but are estimates. Engine work depends on parts availability and what strip-down reveals, so time is not of the essence. We will keep you informed of any material delay, but we are not liable for losses caused by delays outside our reasonable control.
7. Your vehicle while it is with us
7.1 We take reasonable care of your vehicle while it is in our custody and are responsible for loss or damage caused by our negligence.
7.2 Please remove personal belongings before dropping off your vehicle. We cannot accept responsibility for items left inside it.
7.3 If your vehicle arrives in a non-running state, we are responsible only for the work we are contracted to do. We are not responsible for pre-existing faults in unrelated systems (gearbox, brakes, suspension, exhaust and similar), though we will tell you about anything significant we notice.
7.4 Road testing is part of our quality process. We aim to cover up to 100 miles to check for leaks and confirm correct running. If your vehicle needs fuel for testing, fuel used is charged at cost.
7.5 Replaced parts. Parts removed and replaced during the work are available for you to take away when you collect your vehicle — just ask. This does not apply to exchange units (section 4) or parts that must be returned to a manufacturer or supplier under warranty arrangements. Parts not claimed at collection become our property to dispose of responsibly.
8. Collection, delivery, storage and uncollected vehicles
8.1 We will tell you when your vehicle is ready. Please pay and collect within 7 days of that notice.
8.2 From the 8th day, storage is charged at £50 per day.
8.3 If a vehicle remains uncollected, we may serve notice under the Torts (Interference with Goods) Act 1977 of our intention to sell it. We will give at least 3 months’ written notice before any sale, deduct only the sums properly due to us (including storage and costs of sale), and pay any balance to you.
8.4 Vehicle collection and delivery service. We can collect your vehicle and deliver it back to you. Charges depend on distance and are agreed with you in advance as part of your quote. While your vehicle is being collected or delivered by us or by our appointed transport contractor, it is in our custody and section 7.1 applies — we take reasonable care of it and are responsible for loss or damage caused by our negligence. Please tell us before collection about anything that makes the vehicle unsafe to load or transport.
8.5 We will only release your vehicle to you or to a person you have authorised. If someone presents themselves as authorised by you and settles the account in full, we may release the vehicle to them in good faith.
8.6 Vehicles left for an estimate. If you leave a vehicle with us for an estimate and then neither instruct us to proceed nor collect it within 14 days of the estimate being given, storage at £50 per day applies from the 15th day, and clause 8.3 applies to the vehicle as it does to completed work. We will always attempt to contact you before any storage charge begins.
9. Cancellation
9.1 If you are a consumer and your contract was made at a distance (by phone, email or through our website, without visiting our premises) or off-premises (for example, agreed at your home when we collect your vehicle), you have the right under the Consumer Contracts Regulations 2013 to cancel within 14 days without giving a reason.
9.2 For goods, the 14 days run from delivery. For services, they run from the date the contract is made. If you want us to begin work within the cancellation period, we will ask you to confirm this expressly (by ticking a box on our form, or in writing by email or message). If you then cancel before the work is finished, you pay a proportionate amount for the work done up to cancellation; once the work has been fully performed at your express request, you acknowledge that the right to cancel is lost.
9.3 To cancel, contact us by phone or email with your name, contact details and quote or invoice reference. You may use the model cancellation form we can provide on request, but you do not have to.
9.4 Refunds due on cancellation are made within 14 days using your original payment method. Where you return goods, you are responsible for the return cost unless the goods are faulty or not as described, in which case return is at our expense.
9.5 If you are a business customer, orders may be cancelled only by agreement, and you will be responsible for costs reasonably incurred up to cancellation.
10. Our 12-month warranty
10.1 We warrant every reconditioned or replacement engine we supply and fit for 12 months from the date of invoice or 12,000 miles, whichever comes first — parts and labour included. This warranty is in addition to, and does not replace, your statutory rights.
10.2 The warranty covers the engine assembly we supplied or reconditioned — block, head(s) and all internal components we rebuilt — together with our fitting workmanship. Where our work or parts are found to be defective within the warranty period, we will repair or replace at our cost, including the labour to do so.
10.3 The warranty does not cover:
- your original ancillaries refitted to the engine (unless we supplied them new), or damage to our work caused by the failure of one of your ancillaries;
- routine service items — oil, filters, coolant, belts due by age or mileage after fitting;
- damage caused by overheating after coolant loss, or by running the engine with low or no oil, where warning signs were ignored;
- damage caused by accident, misuse, competition or track use, or use contrary to the manufacturer’s guidance;
- engines that have been modified, remapped or tuned without our written agreement, where the modification caused or contributed to the failure;
- vehicle recovery, hire cars, or other consequential costs, except where the law says otherwise.
10.4 To keep the warranty valid we ask for two reasonable things: an oil and filter change within the first 1,000 miles of running in, and servicing thereafter in line with the manufacturer’s schedule. Servicing may be carried out by us or by any established professional garage — you are not required to return to us — but please keep dated, itemised invoices as proof.
10.5 To make a claim, contact us as soon as a fault appears and stop driving the vehicle if continued use could worsen the damage. We will need to inspect the vehicle at our premises (or at a location agreed with us) before any repair is authorised. We will not reimburse third-party repairs carried out without our prior written agreement.
10.6 Heat tabs may be fitted to our engines as an overheat indicator. A triggered or tampered heat tab is evidence of overheating, which we will consider alongside the other facts of the claim.
10.7 The warranty applies to the vehicle the engine was fitted to and is not transferable if the engine is moved to another vehicle. If you sell the vehicle within the warranty period, the remaining warranty transfers to the new keeper on request — just ask us to update our records.
10.8 This warranty is given by Delta Engines Ltd, Unit 15D Askew Farm Lane, Grays, Essex RM17 5XR. It applies within the United Kingdom, runs for the period stated in clause 10.1, and claims are made as described in clause 10.5. A written copy of this warranty is available free of charge on request.
11. Liability
11.1 Nothing in these terms excludes or limits our liability for death or personal injury caused by our negligence, for fraud, under the Consumer Protection Act 1987, or for anything else that cannot lawfully be excluded.
11.2 If you are a consumer, we are responsible for foreseeable loss and damage caused by our breach of these terms or our failure to use reasonable care and skill. We are not responsible for loss that was not foreseeable, or for business losses.
11.3 If you are a business customer, our total liability under the contract is limited to the price paid, and we are not liable for loss of profit, loss of use, or indirect or consequential loss.
12. Events outside our control
12.1 We are not liable for failure or delay caused by events outside our reasonable control, including supplier failures and parts shortages. If such an event continues for more than one month, either of us may end the contract; you pay only for work done and goods supplied, and we return your vehicle.
13. General
13.1 We may use carefully selected subcontractors (for example, machining specialists or couriers) to help perform the contract. We remain responsible to you for the work.
13.2 If any part of these terms is found invalid or unenforceable, the rest remains in force.
13.3 These terms are governed by the law of England and Wales, and the courts of England and Wales have jurisdiction. If you are a consumer living elsewhere in the UK, you may also bring proceedings in your local courts.
13.4 If you are unhappy with our service, please contact us first and we will do our best to put things right. If we are unable to resolve a complaint between us, we will tell you so in writing and provide you with the details of a certified alternative dispute resolution (ADR) provider. We are not currently members of an ADR scheme and are not obliged to use ADR, but we will consider it in individual cases. You can also seek free advice from Citizens Advice (citizensadvice.org.uk), and nothing in these terms limits your right to bring a claim through the courts.
