Every official local authority search comes with the council's backing behind it. Every regulated personal search comes with yours.
That backing is your professional indemnity insurance. It's not paperwork you file once and forget. It's the thing that stands behind every report you send, and the reason a solicitor and their client can rely on your work the way they'd rely on the council's.
Here's what "adequate" cover actually means, what a claim looks like, and why a tight process is the cheapest insurance you'll ever buy.
Why does a search firm need PI insurance at all?
A search firm needs PI insurance because it's what backs the regulated personal search. When an official search has the local authority's statutory remedy behind it, your search has your professional indemnity cover. The Search Code requires subscribing firms to hold "adequate and appropriate" insurance to protect consumers.
Think about what you're actually selling. A solicitor relies on your search to advise a buyer. The buyer relies on that advice to commit hundreds of thousands of pounds. If your search misses something and the buyer loses money, somebody has to make them whole.
On an official search, that's the council. On your search, that's your insurer. PI cover is the difference between an error being a manageable claim and an error being the end of your business.
There's a second reason, and it's commercial. No PI cover, no Search Code registration. No Search Code registration, no lender acceptance. No lender acceptance, no business worth speaking of. The insurance isn't an overhead bolted onto the operation. It's a condition of being allowed to trade in the residential market at all.
What does "adequate and appropriate" cover actually mean?
It means cover that's proportionate to what your firm does, not a fixed pound figure. The Search Code requires "adequate and appropriate" insurance and deliberately sets no published minimum. There's no mandated amount you must carry. The standard is whether your cover fits your risk, full stop.
So what drives "adequate" in practice? Your volume. The values of the properties you search. Your claims history. A firm doing a handful of searches a month in a low-value area carries different risk from one processing thousands across prime London postcodes.
Typical market policies for search firms commonly run from £1m to £2m or more per claim. Treat that as common practice, not a rule. The figure that matters is the one that would actually cover a realistic worst-case error on the work you do.
It helps to separate what the Search Code requires from what the market typically does:
| Question | What applies |
|---|---|
| Is PI cover required? | Yes, if you subscribe to the Search Code |
| Is there a minimum pound figure? | No published or codified minimum |
| What's the standard? | "Adequate and appropriate" to your risk |
| What do policies commonly carry? | Often £1m–£2m+ per claim (typical, not mandated) |
| What sets your "adequate"? | Volume, property values, claims history |
The absence of a codified minimum trips people up. They want a number to tick a box. But "adequate" is a judgement about your operation, and an insurer who knows the trade will price it on your real exposure, not a headline figure.
What does a PI claim against a search firm look like?
Almost always, it's an error in a search that causes a buyer a financial loss. A charge left off the LLC1. A planning enforcement notice missed. A wrong answer to a CON29 enquiry the buyer relied on. The buyer claims, your insurer assesses, and a valid claim gets paid up to the policy limit.
The mechanics are quieter than people expect. There's no court drama in most cases. The solicitor flags the loss, the claim goes to your insurer, and the consumer gets compensated. That's the whole point of the cover.
What makes a claim painful isn't the payout. It's the excess, the premium increase next year, and the time. One avoidable error can shadow your renewals for years. Which is exactly why the work that prevents errors is worth more than any policy line.
It's worth knowing how the loss usually gets traced. The buyer's loss came from advice; the advice came from the solicitor; the solicitor relied on your search. So the line of liability runs back to the answer you gave. That's why the specific wording in a CON29 reply, and the completeness of the LLC1, carry real weight. A vague or hedged answer is harder to defend than a clear, accurate one.
Where do you get search-specific PI cover?
Through brokers who understand the property search trade, and through IPSA, The Association of Independent Personal Search Agents, which offers members access to search-specific cover. Generic professional indemnity policies often don't reflect what a search firm actually does, so specialist cover matters.
The risk in a generic policy is the wording. A broad PI policy written for, say, a marketing consultancy won't anticipate the specific exposures of compiling local authority data and answering statutory enquiries. When a claim comes, wording is everything.
IPSA membership gives you a route to cover designed around the trade, plus peers who've negotiated the same renewals. If you're shopping cover, start with people who already know what a CON29 error claim looks like.
How do you keep cover affordable and claims down?
You produce fewer errors. Premiums and excesses follow your claims history, so the firms with clean records and tight processes get the better terms. The single biggest lever on your insurance cost isn't the broker you pick. It's how rarely you get something wrong.
In twenty years I've watched two firms with near-identical books pay wildly different premiums. The difference was process. One checked every report before it went out. The other trusted that everyone knew what they were doing. Guess which one had the claims.
Three things move the needle. Accurate council data, so you're not guessing at quirks like Rossendale's admin ward requirement. A consistent workflow, so nothing gets answered from memory. And a real report-check step before anything leaves the building: a second pair of eyes on the answers that carry the most liability.
There's a compounding effect, too. A clean claims record doesn't just lower next year's premium. It widens your choice of insurer, which is what gives you negotiating room. Firms with a history of paid claims often find their options narrow, and a thin market is rarely a cheap one.
Good process is the cheapest insurance you'll ever buy. It doesn't appear on a policy schedule. It shows up at renewal.
"People treat the policy as the safety net. It is, but it's the last one. The real protection is the boring stuff: clean data, the same process every time, somebody actually checking the report. Get that right and the claims don't come. Get it wrong and no premium saves you."
