Insurance settlement offer too low? How to challenge it

The first settlement figure your insurer puts on the table is rarely the most they will pay. It is usually built from their contractor rates and a scope of works you have never seen, and it only moves if you challenge it properly. This guide shows you how to take a low offer apart line by line and push it up, in writing, without paying anyone a percentage of your claim.

Why first offers come in low

Most low offers are not malice; they are method. Insurers and their loss adjusters price repairs using nationally agreed contractor and supplier rates, which are discounted far below what you would pay if you rang a local builder tomorrow. A "like-for-like" reinstatement priced at insurer rates can be 30–50% below a retail quote for identical work.

The second driver is the scope of works: the itemised list of repairs the insurer believes are needed. Scopes are often produced from a single visit, or increasingly from photographs alone, and they routinely miss consequential damage: the water that tracked under the floor, the plaster that will need replacing once the wall is opened up.

The regulator has confirmed the problem is real. In its response to the Which? super-complaint on claims handling, the Financial Conduct Authority found that some home insurers had no criteria at all for deciding when a cash settlement was appropriate, and took action against 9 of the 23 firms it reviewed (see the FCA's statement). Average home claims are also getting bigger, around £6,000 in 2025 according to the Association of British Insurers, so the gap between a discounted scope and your real cost is worth serious money.

Step 1: get the breakdown behind the offer

You cannot challenge a number you cannot see. Before anything else, ask the insurer, in writing, for:

• the full scope of works the offer is based on, item by item;
• the rates used for labour and materials, and whether they are insurer network rates or open-market rates;
• any deductions applied: excess, wear and tear, betterment, underinsurance;
• the loss adjuster's report, if one was produced. Insurers often resist sharing it, but you can request the personal data in it through a subject access request; our guide to the loss adjuster's visit explains how.

If the offer arrived as a single unexplained figure, say plainly: "Please provide the itemised scope of works and rates this offer is based on. I cannot assess it without them." An insurer that handles claims fairly, which ICOBS 8.1 requires, should not need asking twice.

Step 2: build your counter-case line by line

This is the part most people skip, and it is the part that wins. General protests do not move claims handlers; matched line items do.

1. Get two or three itemised quotes from local contractors for the same repair. Ask each builder to break the quote down to the same level as the insurer's scope: per room, per task, materials and labour separated.
2. Put the scopes side by side. A simple table works: the insurer's line, your contractors' lines, and the difference.
3. Flag what the insurer's scope missed: items your contractors say are necessary that do not appear at all. Missing items are often worth more than rate differences.
4. Photograph everything the quotes rely on, and keep any specialist reports (damp surveys, structural engineer's letters) with the bundle.

Step 3: negotiate in writing

Phone calls are where low offers survive. Every substantive exchange should be by email or letter, for three reasons: you build the paper trail a complaint or ombudsman referral will need; claims handlers escalate written challenges more readily than verbal grumbles; and promises made in writing get kept.

Structure the challenge like this:

• respond to the offer line by line: accept the lines that are fair, dispute the ones that are not, and attach your quotes as evidence for each disputed line;
• state the figure you believe is right and how you calculated it;
• ask for a response within a stated period, fourteen days is reasonable;
• if money is urgent, ask for an interim payment of the undisputed amount now. Accepting an interim payment does not settle the claim, but never sign anything marked "full and final" unless you mean it.

If the adjuster's scope and your contractors' view of the damage are far apart, ask for a joint revisit with your contractor present. Differences over what needs doing are best resolved standing in the room where it happened.

A workable skeleton for the challenge email: first, thank them for the offer and state plainly that you do not accept it. Second, list each disputed line: their figure, your figure, and the attached quote or report that supports yours. Third, list the items missing from their scope entirely. Fourth, state your revised total and ask them either to agree it or to explain, line by line, why not. Close with the fourteen-day deadline and a request for an interim payment of the undisputed amount. One page, no rhetoric; the attachments do the arguing.

Step 4: turn a stalemate into a formal complaint

If the insurer will not move, or keeps you circling between handlers, stop negotiating and start complaining. Say the word "complaint" explicitly; it triggers a regulated process. The insurer then has eight weeks to resolve it with a final response letter. Our guide to complaining to your insurer covers the letter structure and the deadlines that bind them.

A good complaint about a low offer contains nothing new: it is your line-by-line challenge, the quotes, and the insurer's failure to justify its figure, assembled in one document.

Step 5: the ombudsman

Once you have the final response, or eight weeks pass without one, you can refer the dispute to the Financial Ombudsman Service for free. Be aware of the shape of the field: disputes about claim value made up around 8% of buildings insurance complaint reasons in 2024/25, against 41% for declined claims, according to the FOS's annual complaints data. Value disputes turn almost entirely on evidence, which is why the line-by-line bundle you built in step 2 matters. Our page on ombudsman success rates shows how the odds break down by dispute type.

If the ombudsman finds the offer was too low, it can direct the insurer to pay the difference plus simple interest for the time you were kept out of the money.

Where a low offer fits in the bigger fight

A low offer is one of several ways a claim goes wrong, and the playbook overlaps. If the offer is low because the insurer says part of the damage is not covered at all, that is a partial rejection: start with what to do when a claim is rejected. If the argument is about cash versus repair, or deductions for betterment and matching items, read cash settlement or repair before you accept anything.

And if you are weighing up whether to hand 10% of the settlement to a loss assessor to run this process for you, most of what they do on a domestic claim is the line-by-line work described above.
