Product insurance, read.
Also called: Product liability cover · Public & product liability · Seller insurance · PL insurance
Getting the right cover in place before you sell, because a mains-powered, heat-producing product can hurt someone, and that is the insurer’s whole interest.
A mains heated appliance needs product liability cover before the first sale. It pays the injury and damage claims a fault could cause. The insurer wants your UKCA technical file and test reports, and the exclusions around misuse and unapproved modifications are the part nobody reads.
What product insurance is
Product insurance, in practice product liability cover, pays out when something you sold causes injury or property damage. For a wooden ornament it is a sensible precaution. For a mains-powered appliance that holds heat overnight on a kitchen counter, it stops being optional. A heating element, a power supply and an unattended run while the house sleeps is exactly the risk profile insurers price for, and exactly the one you cannot self-insure as a small seller.
The cover is what stands between a single fault and the end of the company. If a heater control fails and scorches a worktop, or worse, the claim does not care that you are a two-person operation with a careful BS EN 61010 file. Product liability cover absorbs the legal and compensation cost. I treat it as a cost of being allowed to sell a heated product at all, not a line you trim to protect margin.
Read the exclusions before you read the premium
The premium is the number everyone checks first. The exclusions are the part that decides whether you are actually covered when it matters. Two recur on heated-product policies. Misuse: the policy assumes the product is used as instructed, so vague or missing instructions can hand the insurer a reason to decline. Unapproved modifications: if a customer rewires it, or you ship an undocumented change to the heater circuit after the cover was written, the claim can fall outside the policy. The cover is only as good as the conformity story behind it.
Notice the through-line: every box leans on the conformity work you have already done. The technical file is not paperwork for its own sake; it is the document that makes you insurable in the first place.
- First units ship with no cover behind them.
- A single early fault has nothing to absorb the claim.
- You discover the exclusions only when you try to claim.
- The technical file gets assembled in a panic, after the fact.
- Product liability cover is live before any unit goes out.
- Every claim, from unit one, has a policy behind it.
- You have read the exclusions and written instructions to suit.
- The UKCA file and test reports were ready when the insurer asked.
How it fits the bigger picture
Product insurance is activity 10.20.04 in the framework, near the end of Stage 10 Deliver. It sits on the conformity work done earlier in Engineer and Manufacture, and it runs straight into customs (10.20.05), where the same technical file and declarations matter again the moment you ship across a border.
What it can do
It puts a policy between a single product fault and the survival of the company. For a mains heated appliance that is the difference between a bad week and the end of the business. It also forces the conformity file into a state you can hand to a third party, which is useful well beyond the policy itself.
What it can’t do
It can’t make an unsafe product safe, and it won’t cover you for the things you hid or the corners you cut. If the heater design is wrong, insurance pays the first claim and then declines to renew. The cover is a backstop for a product that was built right, not a substitute for building it right.

Try it yourself
Before you list a single unit for sale, get a product liability quote from a broker who understands electrical goods. Hand them the UKCA technical file and the test reports up front, then read the exclusions clause line by line and ask: “what could a customer plausibly do that would void this?” Write your instructions and labelling to close those gaps.

Insuring a heated £149 box with Dan and Anna Hartley in Stockport, and the broker question that made the technical file earn its keep.

Dan wanted to start taking pre-orders the week the first production batch landed. I asked one question before he listed anything: “Is the product liability cover live?” It was not. A wooden box you could probably wing. A mains heated box that runs unattended overnight, you cannot.
What the broker actually wanted
The broker in Manchester was straightforward about it. The premium was a few hundred pounds a year at our volume, fine. But the quote was conditional: they wanted to see the UKCA technical file and the BS EN 61010 test reports before they would write the cover. “We’re insuring a heating element in someone’s kitchen,” the underwriter said. “Show us it was built and tested properly.”
This is where the earlier conformity work paid off twice. The file we had assembled for UKCA was the same file the insurer needed. We did not have to build anything new; we just sent it over. Dan had grumbled about the test cost months earlier. He stopped grumbling when it turned out to be the thing standing between him and an uninsurable product.
The exclusion that changed the labelling
I read the exclusions line by line, which Anna found tedious until we hit the misuse clause. The policy assumed the box was used as instructed. Our draft instructions were thin. So we tightened them: clear maximum dough load, a do-not-cover-the-vents warning, an explicit “indoor use only” line. We pushed back on the broker on one point too, getting a modification clause clarified so a future approved firmware update would not quietly void the cover.
The whole thing cost half a day and a few hundred pounds a year. Set against one scorched worktop claim from a heated product, the maths is not close.
