Withholding Payment From a Builder: The Right Way

The work is wrong, the invoice is due, and every instinct says the same thing: do not pay until it is fixed. That instinct is half right. You have real legal rights when building work falls short, but the way most people act on them, refusing to pay anything until everything is resolved, is legally risky and usually makes the situation worse. Here is what your rights actually are, and how to withhold payment in a way that stands up.

Your rights under the Consumer Rights Act 2015

The Consumer Rights Act 2015 entitles you to building work carried out with reasonable care and skill, and if it is not, to have the work put right or the price reduced. The Act implies these terms into every contract between a consumer and a trader, written or verbal. Materials must be of satisfactory quality and match their description, the service must be performed with reasonable care and skill, and where no price was agreed in advance, you owe a reasonable price.

When the work falls short, the Act gives you an order of remedies. First, repeat performance: the builder must put the defective work right, at their own cost, within a reasonable time and without significant inconvenience to you. If that is impossible, or the builder fails to do it, you are entitled to a price reduction that reflects the shortfall. Notice what the sequence means in practice: the law expects the builder to get a chance to fix the problem before money is the remedy.

The risks of just not paying

Refusing to pay the whole bill puts you in breach of contract if the amount you hold back is more than the defects justify. Withholding is a right of proportion, not a veto. Hold back £12,000 over £900 of defective tiling and you are the one breaking the agreement: the builder can sue for the balance, claim any interest their contract provides, and stand a good chance of winning most of it.

The practical fallout is usually worse than the legal position. Work stops, so you are living in the defect. The builder who was going to fix things for goodwill is now fixing nothing, on advice. And if it does reach court, a judge will ask one question about your withholding: was it proportionate to the actual cost of putting things right? "I was unhappy so I paid nothing" is not an answer that has ever done well.

How to document defects properly

Document defects in writing, with dated photographs, before you mention money at all. Evidence gathered before a dispute exists is worth double evidence assembled afterwards.

• Write one list, item by item, referencing the quote, drawings or specification each item fails against.
• Photograph and date everything, wide shots for context and close-ups for detail.
• Invite the builder to inspect and fix. This is not a courtesy; it is the repeat performance route the Act expects you to offer. Do it in writing with a reasonable window.
• Keep every message. The texts and emails around a defect often decide later who behaved reasonably.
• For serious or contested defects, commission an independent report. A RICS surveyor or relevant specialist can confirm the defect and, crucially, put a professional figure on the cost of remedy. That figure becomes the anchor for everything that follows.

The right way to withhold

If you withhold, withhold a specific amount, tied to a costed defect list, communicated in writing, alongside payment of everything that is not in dispute. Paying the undisputed balance is the move most people miss, and it transforms your position: you are no longer a non-payer, you are a customer withholding a quantified sum for quantified reasons. State the amount held, the items it relates to, the basis for the figure, and that it will be released when the items are put right. Offer access for the fix, propose a deadline, and suggest mediation or an independent expert if you cannot agree.

Disputes that start this way tend to end. Disputes that start with a blanket refusal tend to escalate, and the escalation numbers are grim: the average renovation dispute costs £15,000 and takes 6 to 12 months to resolve. If the relationship was strained from the start by a large upfront payment, that is its own warning sign, and worth reading about in what it means when a builder asks for a deposit.

Why escrow beats a stand-off

A dispute over money already sitting in escrow is structurally different from a dispute over an unpaid invoice, because nobody is withholding anything: the funds are frozen where they already sit. On a milestone schedule, each stage's money is deposited into a safeguarded account before the stage begins. If a stage is disputed, that milestone's funds simply stay locked, untouchable by either side, until the issue is resolved, with an independent RICS assessment available if the two of you cannot agree. Platforms like Renopay hold the funds with Online Payment Platform (OPP), a payments provider authorised by the FCA.

The pressure this removes is exactly the pressure that makes withholding disputes ugly. The builder is not chasing money you are sitting on, and you are not being chased for money you fear losing: the disputed stage is contained, and only that stage, so the rest of the project can carry on. Most withholding fights are really fights about the final stage, which is why we wrote a separate guide to snagging and the final payment.

Hold back the right amount, in writing, with the evidence to support it. Better still, put the money somewhere neither of you has to withhold it from the other. Join Renopay at renopay.co.uk.

Frequently asked questions

Can I refuse to pay my builder for poor work?

You can withhold a proportionate amount reflecting the cost of putting the defective work right, after giving the builder a reasonable chance to fix it, which the Consumer Rights Act 2015 expects. Refusing to pay the entire bill over limited defects puts you in breach of contract.

How much money can I hold back from a builder?

An amount that matches the realistic cost of remedying the specific defects, ideally supported by an independent estimate or surveyor’s report. Pay the undisputed balance and set out the held amount and its basis in writing.

Can a builder take me to court for not paying?

Yes. A builder can bring a county court claim for the unpaid amount plus any contractual interest, and claims under £10,000 in England and Wales go through the small claims track. Proportionate withholding, documented defects and a written offer to release on completion of repairs are your defence.
