Warranty terms are usually written once, copied from another shop, and then never revisited. They are also the terms that decide who pays when a part fails, which makes them one of the few pieces of paperwork that directly affects margin.

The starting point is not what a competitor offers. It is what your supplier gives you, because the gap between those two numbers is the risk you carry.
<h2>Why warranty terms decide your margin</h2>
Because the difference between two warranty periods is a cost with no line on the invoice.

A shop that receives twelve months of cover on a display assembly and offers its customers three has taken on nine months of exposure. On a screen that lifts at eight months, the supplier declines it as outside their window and the customer still has a valid claim against the shop. The shop pays for a part it cannot claim back.

That cost does not appear anywhere until it happens, which is why it is worth turning into a deliberate decision rather than something inherited from a template.
<h2>How long should a repair warranty be?</h2>
At least as long as your supplier’s cover, and only as long as you can honour.

There is no fixed legal length for a warranty a business chooses to offer. What matters is that the customer-facing period does not outlast the supplier-facing one, unless the difference has been priced in. Even then, a shop should not promise a duration for which it has no process, because an unhonoured warranty costs more in reputation than the repair would have cost outright.

Three months, six months and twelve months are all common in the UK trade. The useful test is not which sounds best but which one the shop can administer: a warranty that requires proof, batch references and photographs only works if those records exist, which is the habit covered in our guide to <a href="/blogs/parts-returns-and-doa-claims/">building a parts returns process</a>.

<h2>What should the warranty cover?</h2>
The workmanship and the part, for the failures you can defend.

A workable warranty covers the repair itself: a bonded panel that lifts, a battery that fails to hold charge, a port assembly that stops working, a connector that comes loose. Those are failures that trace back to the part or the fitting, and they are the ones a shop can assess on the bench.

What it should not do is promise the device’s overall condition. A repair warranty is not a device warranty, and customers who understand the difference are far easier to deal with when something else fails on an ageing handset.

<h2>How do consumer rights differ from your warranty?</h2>
They sit underneath your terms and cannot be removed by them.

For retail customers in the UK, the statutory position is set by the <a href="https://www.legislation.gov.uk/ukpga/2015/15/contents" rel="nofollow">Consumer Rights Act 2015</a>. A written warranty that offers less than that position does not replace it. This is why competing on warranty length is a poor strategy: the floor is already set, and going above it is a commercial choice rather than a legal one.

Where the repair is trade-to-trade rather than retail, the position is different and depends on the contract between the two businesses. A shop selling to another business should say clearly which set of terms applies, because the two carry different expectations.
<h2>How does the device’s own warranty interact?</h2>
It sits with the manufacturer, and the customer may still hold it.

A device repaired by an independent shop is a separate question from the manufacturer’s own cover, and the answer depends on the age of the device and what was replaced. Customers often ask, and the honest position is that the two are independent: your warranty covers your work, and the manufacturer’s position is theirs to state.

Apple publishes its own service routing for <a href="https://support.apple.com/en-gb/iphone/repair" rel="nofollow">iPhone</a> and for <a href="https://support.apple.com/en-gb/mac-laptops/repair" rel="nofollow">Mac laptops</a>, and its guidance on <a href="https://support.apple.com/en-gb/103269" rel="nofollow">the batteries used in iPhone</a> explains what the device reports about its own parts. Knowing what the manufacturer says means you can answer the question without guessing.
<h2>How do you price warranty risk?</h2>
By measuring it rather than estimating it.

The cost of warranty work is the number of claims multiplied by what each claim costs, including the labour. For most shops that number settles quickly once returns are recorded by part type and failure mode, and it is usually smaller than the fear of it and larger than the assumption.

Once it is known, it goes into the labour rate rather than onto the invoice as a visible charge. The pricing structure in our guide to <a href="/blogs/how-to-price-phone-repairs-uk-shops/">building a repair price that survives</a> includes that allowance as a defined component, which is what stops it being absorbed silently.
<h2>What should you put in writing?</h2>
The part fitted, the period, the exclusions, and the process.

Write on the invoice what was fitted and what the warranty covers, with the period stated as dates rather than as a duration. State the exclusions in plain words. And say what the customer should do if the fault returns, because a clear process is what turns a claim into a repair rather than a dispute.

For a device repaired with a fitted part, it is also worth noting that a bonded panel or a battery has its own care requirements. The guidance on <a href="/blogs/iphone-screen-separating-from-the-frame/">why panels lift from the frame</a> explains which in-service failures are attributable to the bond, and that distinction is exactly the one a warranty conversation turns on. Where a replaced part is written off, disposal still has to follow the <a href="https://www.legislation.gov.uk/uksi/2013/3113/contents" rel="nofollow">Waste Electrical and Electronic Equipment Regulations 2013</a>, and the general safety obligations that apply to goods placed on the market sit with the <a href="https://www.gov.uk/government/organisations/office-for-product-safety-and-standards" rel="nofollow">Office for Product Safety and Standards</a>.
<h2>What should you record?</h2>
Which part, which batch, and whether it came back.

Record the part, its batch reference, the date and the outcome of every claim. Those four fields tell a shop what its warranty actually costs, which parts produce returns, and whether the terms it offers are matched by the cover it receives.

That record is also what makes a longer warranty affordable. A shop that knows its claim rate can offer twelve months on a part with confidence; one that does not is guessing, and guessing is what makes shops shorten their terms without knowing whether they needed to.
<h2>How do you handle a claim that is not your fault?</h2>
By showing the customer what the terms say and what you found, in that order.

Most disputes are not about whether the fault is covered. They are about whether the customer was told beforehand. A device returned with impact damage after a screen repair is a straightforward exclusion if the terms said so and were on the invoice; the same device is an argument if the customer is hearing the exclusion for the first time.

The practical sequence is to show the terms, then show what you found. A photograph of the damage alongside the wording that excludes it settles the question in one look, and it does so without the conversation becoming personal. Where the fault is genuinely covered, the same evidence works in the opposite direction: you already have the intake record, so the claim is processed rather than discussed.

Where the fault is neither clearly covered nor clearly excluded, the commercial answer is usually to repair it and treat the cost as a marketing expense. A shop that does that occasionally and says so plainly earns more in referrals than it loses on the part, and it avoids the small claims that consume disproportionate time.
<h2>How does warranty work change what you hold in stock?</h2>
It argues for holding the parts you claim on most, rather than the parts you fit most.

A shop that keeps two panels of its highest-return line in stock converts a warranty claim from a two-day turnaround into a same-day one, which is the difference between a minor inconvenience and a lost customer. The same logic applies to the batteries and port assemblies that produce repeat work.

That position is worth reviewing alongside the rest of the stock plan, because the parts you claim on are not always the parts you sell. A line that turns over steadily but never comes back does not need a warranty buffer; a line that comes back occasionally does, even if the volume is lower. The reasoning is the same as the one behind <a href="/blogs/how-to-price-phone-repairs-uk-shops/">pricing a repair so the parts margin survives</a>, where the warranty allowance is priced rather than assumed.

<h2>What is the one habit that makes a warranty affordable?</h2>
Recording the outcome of every claim, from the first month the terms are in force.

A shop that knows its claim rate can offer a period that matches its supplier cover with confidence. One that does not is guessing, and guessing is what makes shops shorten their terms without ever knowing whether the cover was actually costing them anything. The record turns the decision from a fear into a number.

<h2>FAQ</h2>
<p class="faq-q">How long should a phone repair warranty be in the UK?</p>
<p class="faq-a">There is no fixed legal length for a repair warranty you choose to offer, but it should be at least as long as the cover you receive from your parts supplier. If a supplier covers twelve months and your customer terms cover three, the gap in the middle is risk you carry without having priced it. Match the two, or price the difference deliberately.</p>
<p class="faq-q">What should a repair warranty cover?</p>
<p class="faq-a">The workmanship and the part you fitted, for the failure modes you can defend. A screen assembly that lifts at the bracket within the period, a battery that fails to hold charge, or a port assembly that stops working are the normal cases. Cover what you control and say clearly what you do not, rather than offering a blanket promise you cannot keep.</p>
<p class="faq-q">What should a repair warranty exclude?</p>
<p class="faq-a">Damage after the repair: drop damage, liquid contact, and any later work carried out by another shop. Those are standard exclusions and customers accept them when they are written down. What customers do not accept is discovering an exclusion for the first time when they make a claim, which is why the terms belong on the invoice rather than in a drawer.</p>
<p class="faq-q">Do consumer rights apply on top of my repair warranty?</p>
<p class="faq-a">Yes, for retail customers in the UK. Your own warranty sits on top of the statutory rights set by the Consumer Rights Act 2015, and it cannot take anything away from them. A warranty that is shorter than the statutory position is still subject to that position, which is one reason it is better to offer terms you can actually honour than to compete on length.</p>

</div>
Warranty terms are a pricing decision wearing a legal coat. Match your customer period to your supplier cover, cover the part and the workmanship rather than the device, write the exclusions on the invoice, and record enough to know what claims actually cost you. Do that and the terms stop being a copied paragraph and start being a managed cost.
