If you are taking a builder to small claims court, the court will not generally let you call an expert witness, and you must file every document you plan to rely on at least 14 days before the final hearing.
Before you think about court
This is general information, not legal advice, and the court material below applies to England and Wales. Nobody can tell you what a court will decide, and nobody can tell you what your builder will do next. What follows is simply what the rules say.
Under the Consumer Rights Act 2015, section 49, every contract to supply a service includes a term that the trader must perform it with reasonable care and skill. If the work falls short of that, section 55 gives you the right to ask the trader to redo the work, within a reasonable time and without significant inconvenience to you, and at no cost to you including labour and materials. If that is not possible, or not done properly, section 56 gives you the right to a price reduction instead. Any refund owed under section 56 must be paid within 14 days of the trader agreeing you are entitled to it, by the same method you used to pay, with no fee charged for making it.
Keep those two routes, repeat performance or a price reduction, in mind before you file anything. Court is what happens when those requests have gone nowhere.
The small claims track and the 14 day rule
Civil Procedure Rules Part 27 covers the small claims track, which generally applies to claims not exceeding £10,000. Once a claim is allocated to this track, the standard directions require each party to file and serve on every other party copies of all the documents they intend to rely on at the hearing, and this must happen at least 14 days before the date fixed for the final hearing.
That 14 day point is not a soft deadline. It is the date by which your photographs, invoices, written reports, letters and anything else you plan to put in front of the judge needs to be in the other side’s hands as well as filed with the court. Leaving it until the week of the hearing is leaving it too late.
- Work out what documents you actually have: contract or quote, invoices, payment proof, photographs, written correspondence
- Organise them in a way a judge who has never seen the property can follow
- File and serve everything at least 14 days before the hearing date, not after
Why you cannot just bring an expert
Rule 27.5 of Part 27 is blunt: no expert may give evidence, whether written or oral, at a hearing without the permission of the court. You cannot simply turn up with a surveyor or an engineer and have them speak for you. If you want expert evidence admitted, you need the court’s permission first, and that is a separate step from preparing your own documents.
This matters because small claims hearings do not work the way people expect from television. The strict rules of evidence do not apply, and the court does not need to take evidence on oath. The whole track is built to be used without expert witnesses and often without lawyers. What carries weight is your own documented record: what you saw, when you saw it, and what it looked like.
Adjudication is not available to you as a homeowner
You may come across adjudication as a faster alternative to court for construction disputes. Section 108 of the Housing Grants, Construction and Regeneration Act 1996 gives a party to a construction contract the right to refer a dispute to adjudication, with a decision due within 28 days of referral, which is binding until the dispute is finally resolved another way.
Section 106 of that same Act closes this off for most homeowners: it does not apply to a construction contract with a residential occupier, meaning a contract principally for work on a dwelling that one of the parties occupies, or intends to occupy, as their home. If the builder worked on the house you live in, you have no statutory right to adjudicate. Small claims court, or another route you take yourself, is what is available to you.
How long you have to bring a claim
Section 5 of the Limitation Act 1980 sets the general limit: an action founded on simple contract must not be brought after six years from the date the cause of action accrued. That is the outer limit for most builder disputes based on a contract, not a reason to wait. Evidence fades, memories fade, and people move on, so filing sooner rather than later is always easier for you to manage.
