If you’ve had work done at home and there’s a problem caused by the trader, you should be able to get it fixed - or get at least some of your money back.
Whatever the problem is, you’ll need to talk to the trader and come to an agreement.
You should take up the problem with the trader who arranged the work, even if they ‘sub-contracted’ (passed on) all or some of it to another business.
Before you do that, it’s a good idea to:
gather any paperwork and receipts
take photos to use as evidence of the problem
make notes about what’s happened, including dates and times
What you should do next depends on the type of problem.
