The schedule of loss — pricing your building claim

The short answer: a schedule of loss is a simple table that converts your dispute into a number: each defect, the evidence for it, and the cost to remedy. Judges decide claims, not grievances — and a clear, evidenced schedule is the difference between a vague "he ruined my extension, I want £15,000" and a claim a judge can award.

Where the numbers come from

  • Remedial cost: written quotes from independent trades (two or three is the credible zone — one is an opinion, five looks shopped). The measure is a reasonable cost, so explain any outlier choice.
  • Diminution: if the finished work is worth less than promised but you're keeping it, the loss is the difference in value — usually evidenced by an agent's or surveyor's opinion.
  • Consequential losses: hire costs, accommodation, storage — receipts only, and proportionate.
  • Your time: generally not recoverable for a homeowner managing their own project. Don't include it.
  • Expert/report fees and court fees: recoverable if reasonable — pre-action conduct expects proportionate steps, and small claims costs rules limit what the loser pays, so keep it lean.

The disciplines that make it credible

1. Every figure has a document behind it — quote, invoice, or receipt. No round guesses. 2. Match defects to evidence by number — "Defect 3: see photos 20–24, message thread 12 May". The judge should never have to hunt. 3. Be consistent everywhere — the schedule, the letter before action, and the claim form must carry the same total. Changing numbers between documents reads as invention. 4. Round sensibly — £2,408.72 reads as calculated; £2,400.00 reads as considered. Either is fine; never round up to "make the claim worth it". 5. Deduct what you've recovered — if the builder already paid £500 toward a fix, net it off and say so. Honesty here is a credibility multiplier.

If the builder claims set-off

They may counterclaim (e.g. "unpaid variations"). Your schedule should anticipate this: list any genuinely outstanding sums you concede, and why the rest isn't owed. A schedule that survives a counterclaim is one that already did the maths.

Using it

  • Enclose the schedule with your letter before action.
  • Carry the same total into the claim form and your witness statement.
  • Update it if quotes change — and date the update.
