What is the problem?
Pick one to see the likely cause and a starting price.
Likely a combi fault
from £95On a combi boiler this is often a stuck diverter valve or low pressure. Check the pressure gauge first, then book a repair if it reads between 1 and 1.5 bar.
Likely a slow leak
from £95Pressure that falls again after a top-up means water is escaping somewhere. Common places are a radiator valve, the pressure relief pipe or the expansion vessel.
Air or sludge in the system
from £450Cold at the top means trapped air, which you can bleed yourself. Cold at the bottom or cold all over usually means sludge, and a power flush clears it.
Turn off the water first
from £120Close the stopcock, usually under the kitchen sink, and switch off the boiler. Then call us. An engineer can be with you within two hours.
A blockage we can clear today
from £120Slow sinks and gurgling toilets mean a partial blockage. We clear it, then check the pipe with a camera so it does not come back.
Leave the house and call 0800 111 999
Do not use switches or flames. Open the doors, turn off the gas at the meter if you can, and call the National Gas Emergency line. When it is safe, we find and fix the fault.

About Tidewell
A Colchester firm that answers its own phone
Dan Whitlock started Tidewell in 2011 with one van and a list of neighbours. Today six engineers cover the town and the villages around it, and Lucy in the office still takes most of the calls.
We keep the area small on purpose. It means short drives, quick call-outs, and engineers who already know the houses on your street.
