Problems left behind by rogue tradespeople carrying out shoddy work cost households a total of £1.9bn a year to fix, according to a new survey.

Almost one in five (17%) of the 18 million homeowners who employed tradespeople in the last 12 months have had to have at least part of the work redone, spending an average of £600, the survey by TrustMark (a government endorsed quality mark for traders) revealed.

Nearly half admitted they were not confident in knowing where to report problems and a third (34%) said they would not know how to get a problem resolved.

Avoid rogue traders

One in 20 of those surveyed admitted they chose a tradesperson based on the cheapest quote.

We've launched the Which? Trusted Traders service in London and the South East, with plans to expand the service across the country.

Our traders have gone through a rigorous assessment process before becoming a Which? Trusted trader.

The service is available to anyone searching for tradespeople in the home improvements and motoring repairs industries.

Building work disputes

It can be frustrating when a home improvement goes wrong, but there are steps to take in order to get the situation resolved. If you have a dispute with a builder, you are protected by the Supply of Goods and Services Act.

The Act stipulates that any building or decorating work should be completed with reasonable care and skill, within a reasonable time and using materials that are of satisfactory quality and fit for purpose.

See our guide for how to complain if you're unhappy with building work.

If you cannot resolve your problem with the builder, you can use a dispute resolution scheme.
