What to have ready before you claim

The order it actually happens in

A service interaction follows a predictable sequence, and each step is a gate. If you cannot pass a gate, the conversation stops there regardless of how valid your claim is.

1. "What's the model and serial number?" — identifies the unit and pulls up the warranty record on their system.
2. "When did you buy it?" — establishes whether you are inside the period.
3. "Do you have the invoice?" — the proof behind your answer to the previous question.
4. "What exactly is wrong?" — determines whether the fault is a covered defect or an excluded cause.
5. "Has anyone else worked on it?" — checks for the most commonly enforced exclusion.

Every one of those is answerable in seconds if you prepared, and a half-hour of searching if you did not.

The checklist

Essential — do not start without these

• Proof of purchase. The tax invoice or bill, showing the date, the seller, the item and the amount. A photograph is almost always accepted; the original is occasionally demanded for high-value items.
• Model number. Not the marketing name. The exact string from the rating label, including suffixes — these frequently indicate the regional variant, and the wrong one sends the wrong part.
• Serial number. From the unit itself, not the box, since boxes get mixed up. See finding serial numbers.
• Purchase date. Stated confidently and matching the invoice.
• A clear description of the fault. What happens, when it started, whether it is constant or intermittent, and what you have already tried.

Strongly recommended

• Warranty card, if one came with the product, particularly where it was stamped by the dealer at purchase.
• Installation report or job sheet for anything professionally installed. This is what proves an installation-date start, which may be weeks in your favour.
• Photographs or a short video of the fault. Intermittent faults have a habit of not reproducing in front of a technician. A video is the difference between "cannot find fault" and a repair.
• Previous service records for the same unit. A recurring fault is a stronger case than a new one, and in some terms a repeated failure entitles you to replacement rather than another repair.
• The original packaging, where you still have it. Not usually required, but it makes a replacement or a pickup considerably simpler.

Worth having to hand

• The seller's name, branch and contact details.
• The order number, if bought online.
• Any extended-warranty or protection-plan policy number, with its own expiry date.
• The registration confirmation, if the product required registering.

When the receipt has faded or gone

Thermal till receipts fade to blank within one to two years — well inside most warranty periods. This is the most common reason a valid claim collapses. If it has already happened, work through these in order:

1. Card statement. Shows the merchant, the date and the amount. Not itemised, but it establishes that you bought something from that shop on that day for that sum, which is often enough when combined with the serial number.
2. Email confirmation. Search your inbox for the brand, the model, the shop name, or the amount. Online orders almost always leave a trail, and most retailers keep order history in your account indefinitely.
3. Ask the seller for a duplicate. Most retailers can reprint from their system given the date and the card's last four digits. Many will do it over the phone.
4. The serial number itself. Manufacturers can often look up the manufacture and dispatch date from the serial, and some will treat that as a basis for warranty even without your invoice — usually by assuming a standard shelf period, which works against you slightly but is far better than nothing.
5. Warranty registration. If you registered the product online when you bought it, the manufacturer already has your purchase date on file.

Report the fault before the deadline, not the repair

This is the single most useful thing on this page. What matters for most warranty terms is the date you reported the fault, not the date it was inspected or repaired. A service centre booked out three weeks does not shorten your warranty — but only if you can show when you reported it.

So: report in writing, or get a reference. An email, a support ticket number, a complaint number, a chat transcript, a dated acknowledgement. A phone call with no record is worth very little if the conversation turns into a dispute two months later.

If you can only get through by phone, send a short follow-up email the same day: what you reported, when, who you spoke to and what they said. You are not being difficult; you are creating the dated record that protects you.

When you get bounced between seller and manufacturer

A familiar loop: the shop says it is the manufacturer's responsibility, the manufacturer says to go back to the shop. Both would prefer the other to handle it.

• Start with the manufacturer's authorised service centre for a technical fault inside the warranty period. That is what the network exists for.
• Go to the seller where the goods were faulty on arrival, dead out of the box, or not as described. That is a sale-of-goods matter rather than a warranty one, and it sits with whoever sold it to you.
• Put it in writing to both, with the other copied in, once you have been bounced once. A loop is much harder to sustain when both parties can see the same thread.
• Keep a log. Date, time, who you spoke to, reference number, what was said. Boring to maintain, decisive in a dispute, and it is what a consumer forum will ask for first if it gets that far.

How to describe a fault so it gets fixed

"It's not working" starts an investigation. A specific description starts a repair.

Instead of	Say
"The washing machine is broken."	"It fills and drains normally but the drum does not spin on any cycle. Started three days ago. No error code shown."
"The laptop keeps shutting down."	"It powers off without warning after roughly twenty minutes under load, every time. Fine when idle. Started after it was two months old."
"The fridge isn't cold."	"The freezer compartment is at normal temperature but the main compartment stays around room temperature. The compressor runs continuously."

Include when it started, whether it is constant or intermittent, any error code exactly as displayed, and what you have already ruled out. If you have a video of the fault happening, say so at the start — it changes what the technician brings with them.

Before the technician arrives

• Clear access to the unit, including behind and underneath.
• Have the documents physically to hand, not on a phone that is about to die.
• Reproduce the fault just before they arrive, if you can, so it is in a failed state.
• Do not attempt a repair yourself in the meantime. Opening the case is one of the few exclusions that is checked and enforced consistently.
• Get the job sheet before they leave, with the fault, the parts and the date on it. Then photograph it and attach it to the product record.

If the claim is refused

1. Get the reason in writing. A verbal refusal is not something you can escalate. Ask for the specific clause relied on.
2. Read that clause. A surprising number of refusals cite an exclusion that does not cover the facts, and go away when challenged specifically.
3. Escalate within the brand before going outside it. Service centres are often franchised; the brand's own customer relations team frequently reaches a different answer.
4. Then escalate externally. Consumer protection bodies, the relevant ombudsman or a consumer forum, depending on where you are. Your dated log and documents are the case.

The point of tracking warranties is this moment. The tracker keeps the invoice, the serial number, the purchase date and the seller attached to each product, and scores each record on whether it would survive this checklist — so you find out what is missing while there is still time to fix it.
