What can I do if a builder does bad work?
Researched by the LokalMatch editorial team1 answer
The plastering is uneven and one of the new sockets does not work. The builder has been paid most of the money and is not answering the phone.

Ask for it to be put right first, in writing. The Consumer Rights Act 2015 gives you a right to repeat performance: the trader has to do the work again to the extent needed to bring it into line with the contract, within a reasonable time, without significant inconvenience to you, and at their own cost — including labour and materials. You do not pay twice to get what you already bought.
If repeat performance is impossible, or cannot happen in a reasonable time or without real inconvenience, the right changes to a price reduction. How much depends on the gap between what you paid for and what you actually got, and it can run to the whole price where the work gave you no benefit at all and somebody else has to start from scratch.
Put the request in writing and keep it, even if you have been talking on the phone. A dated letter or email setting out what is wrong and what you are asking for is the thing that matters later, whether the argument ends in a settlement or in court.
