Do you think you're being overcharged?

Be aware of the difference between a "quote", which is a fixed price, and an 'estimate', which is not.

Don't pay all the money up front - always keep some back in the event of a dispute.

Even if you didn't agree a price before the work started, or if you were working from an estimate, the law says you should pay no more than a reasonable amount for services. You do not have to pay whatever the trader is asking.

It's reasonable to expect a job to go over budget by 5% or 10%. If the trader wanted to raise the price by any more than that, though, they need to get your approval first.

If you feel the trader is charging you too much, get a few quotes from other professionals in the same trade so you can make a price comparison.

If those quotes are all cheaper, get an average price. Then give your trader that figure and say it is all you are willing to pay.

If you pay a reasonable amount for the service, the law is on your side.
