What should I do if work has gone wrong?
If the complaint is about your own building work, you should initially raise it with your builder. You should always use a reputable builder who is a member of a trade association - such as the Federation of Master Builders (FMB). The association has a published complaints procedure, which sets out what you can do if your building work has gone wrong.
Local council building control teams inspect building work and certify it meets building standards. If they find work is not up to minimum legal standards they have the power to require the builder to bring it up to the required level. So if you have concerns about the quality of work on your building site you should contact the local council building control team to discuss your concerns.
