Rules that apply in England

Questions from Cosham
Is the survey free in Cosham?
This is a charged visit because it is servicing, testing or repair work. We tell you the cost before booking. Surveys for new installations on the UK mainland are free.
Why is my extractor fan humming but not spinning?
A humming fan that does not spin often has a failed capacitor, seized bearing or obstruction. It should be switched off until repaired.
Why is water dripping from my ventilation?
Drips usually come from condensation in an uninsulated duct, a blocked condensate drain or a duct sloping the wrong way.
