A useful repair warranty says what the shop promises, how a customer can make a claim and what happens next. It also states clearly that the policy does not replace the customer's statutory rights.
There is no universal warranty period that every UK phone repair shop must copy. The right period depends on the part, supplier support, repair method and commercial promise. A voluntary 90-day or 12-month warranty may be sensible for a particular repair, but the printed number does not cancel obligations under consumer law.
Use the template below as a starting point, then have it reviewed for your business, services and jurisdiction. It is general information, not legal advice.
Quick answer: a repair warranty should name the exact repair and part, define the extra promise in plain English, preserve statutory rights, explain how to claim and connect every decision to intake and completion evidence. A copied period or blanket exclusion is not a substitute for that control system.
What UK law requires
Section 49 of the Consumer Rights Act 2015 says a consumer service must be performed with reasonable care and skill. Information you give about the service can also become binding under section 50.
Where the statutory conditions are met, remedies can include repeat performance or a price reduction. A shop cannot use a warranty exclusion to remove those rights.
This creates an important distinction:
- Statutory rights arise from law and depend on the facts of the transaction.
- Your voluntary warranty is the extra, clearly defined promise your shop makes.
The government's supported Business Companion guide to consumer services is a practical reference for traders. The CMA's fair-contract guidance, updated on 22 July 2026, says consumer terms must be fair and transparent and warns against warranty wording that leaves customers with narrower or weaker rights than the law provides. If a dispute is complex or high value, take legal advice rather than forcing the facts into a template.
Decide the policy before writing it
Complete this table for every repair category you sell:
Covered work | Does the promise cover both the fitted part and workmanship?
Start date | Does cover begin on completion, collection or delivery?
Period | What period can the shop and supplier genuinely support?
Evidence | Which intake photographs and tests prove pre- and post-repair condition?
Exclusions | Which later faults are unrelated to the agreed repair?
Remedy | Will a valid claim be diagnosed, re-performed, replaced or refunded?
Logistics | Who pays postage for a valid mail-in claim?
Data | What backup and access-code warning is given before further work?
Download the repair-shop warranty control register. Use one row per repair promise or live claim. The example rows test whether the same wording produces a consistent decision; they are not recommended warranty periods or legal conclusions.
Do not promise a “lifetime warranty” unless the term, covered lifetime and exclusions are defined in plain English and the business can honour it. A dramatic headline followed by exclusions that remove most of the promise is likely to create complaints.
Copyable repair warranty template
Replace every bracketed item. Delete any clause that does not match the service you actually provide.
1. Business and repair details
This warranty is provided by [legal business name], trading as [shop name], of [business address]. It applies to repair reference [ticket number], completed on [date], for [customer name and device]. The agreed repair and fitted part are shown on the invoice.
Use the legal entity, not only a trading name. The ticket, receipt and warranty should all point to the same business and repair.
2. The warranty promise
We warrant the fitted [part description and quality tier] and our workmanship for [period] from [start event]. If the same part or workmanship fails during that period, we will inspect the device and, where the claim is valid, provide the remedy described below.
Name the part quality accurately. Avoid undefined labels such as “OEM quality” unless your supplier evidence and customer explanation make the term clear. Our OEM versus aftermarket parts guide covers that conversation.
3. What is covered
The warranty covers a fault in the fitted part or the workmanship used for the repair stated on the invoice. It does not automatically cover a different fault elsewhere in the device.
Examples can help, but only include faults your diagnostics can distinguish. For a screen repair, a dead pixel caused by the supplied display may be relevant; new impact damage is a different event.
4. Exclusions
The voluntary warranty does not cover new accidental or liquid damage, misuse, unauthorised work after our repair, faults unrelated to the agreed repair, data or software loss, consumable wear that was explained at sale, or a device that cannot be safely inspected. We will explain the evidence for any declined claim.
Do not use a vague exclusion such as “any physical damage voids all cover” without considering whether the damage is actually connected to the claimed fault. An unrelated mark should not become an automatic escape route.
5. Making a claim
Contact us at [email/phone/web address] with the repair reference, a description of the fault and any useful photographs. We will acknowledge the claim within [time] and arrange inspection by [shop visit/postal process]. Do not send a device until we provide packing and delivery instructions.
Set a response time the shop can consistently meet. The policy should tell a customer what happens, not merely say “contact us”.
6. Inspection and remedy
We will compare the reported fault with the original intake condition, repair notes and completion tests. If the voluntary warranty applies, our first proposed remedy will be [repeat the repair/replace the part] within a reasonable time and without significant inconvenience. If that remedy is impossible or unsuccessful, we will discuss the appropriate next step, which may include a price reduction or refund where required.
This clause should match the Consumer Rights Act rather than trying to invent a private remedy hierarchy that overrides it.
7. Postage and access
For a mail-in claim, [state who initially pays postage and how valid-claim costs are handled]. The customer is responsible for backing up data where possible. We will only request the access needed to diagnose the claim and will handle personal data under our privacy notice.
Be explicit about postage. A “free repair” can still feel misleading if a customer discovers an unexplained insured-delivery cost after the fault appears.
8. Statutory rights
This voluntary warranty is in addition to, and does not affect, your statutory rights under UK consumer law.
Keep that sentence prominent. Do not bury it behind a link or put contradictory wording elsewhere.
That sentence does not rescue an otherwise unfair exclusion. Check the practical effect of the whole document: the headline, intake explanation, exclusions, evidence threshold and remedy must all tell the same story.
Evidence that makes the policy workable
A policy cannot resolve a dispute if the repair record is empty. Keep a consistent evidence trail:
- device identifiers and reported fault;
- intake photographs showing existing damage;
- customer-approved work, price and part tier;
- technician notes and the part batch or supplier reference;
- post-repair test results;
- collection or delivery confirmation;
- later claim photographs, inspection and decision; and
- the remedy and customer communication.
Only retain personal data for as long as there is a justified purpose. The repair-shop GDPR guide explains how to separate useful repair evidence from unnecessary device access.
A fair claim workflow
Use the same steps regardless of who handles the enquiry:
- acknowledge the claim without deciding fault in the first message;
- verify the ticket and warranty promise;
- inspect the device against the original record;
- identify whether the fault concerns the supplied part, workmanship or something unrelated;
- record the evidence and proposed remedy;
- explain the decision in ordinary language; and
- retain the outcome for supplier recovery and quality review.
Track claim rate by part SKU, supplier and technician. The point is not to reject more customers. It is to spot a weak batch or process before it creates another ten claims.
Our guide to handling repair-shop disputes covers escalation and communication.
Common warranty mistakes
Copying another shop's period
The other business may use different suppliers, margins and tests. Set a period you can explain and support.
Treating supplier cover as customer cover
Your contract with a customer is separate from your supplier's RMA process. A slow supplier does not suspend the customer's rights.
Promising more than the system records
If staff cannot see the exact part, completion date and terms, the promise will be applied inconsistently. Put the warranty on the repair ticket rather than relying on memory.
Using exclusions as a refusal script
An exclusion needs a factual connection to the claim. Record the diagnosis and explain it.
Forgetting remote customers
Mail-in repairs need packaging, delivery-risk and communication terms. Read the mail-in repair service guide before adapting the template for postal work.
Before publishing your policy
- Replace all placeholders.
- Make the legal entity and contact route clear.
- Match the policy to each part tier and service.
- Test the claims workflow with the people who will use it.
- Check the policy against current consumer law and your insurer's requirements.
- Ask a UK solicitor to review material exclusions, high-value devices and cross-border sales.
- Put the same version on the website, ticket and receipt.
A shorter policy that staff can follow is safer than five pages of copied exclusions. The repair record, diagnosis and fair remedy are what make the promise credible.
What changed in this review
The 26 August 2026 review added the current CMA fairness guidance, an original claim-control register, a five-stage warranty loop and clearer separation between voluntary promises and statutory remedies. Universal “industry-standard” warranty periods remain deliberately excluded.
