Heating FAQs
Are your engineers Gas Safe registered?
Yes — every Fixie heating engineer is Gas Safe registered, which is a legal requirement for gas work in the UK. You can ask to see their registration card on arrival.
My boiler is old — will you still repair it?
We service and repair most boiler makes and models regardless of age. If your boiler is beyond economical repair, your engineer will advise you honestly before any cost is incurred.
How often should I service my boiler?
Once a year. An annual service keeps your boiler running efficiently, maintains your warranty, and is often a condition of your home insurance.
What is a power flush and do I need one?
A power flush removes sludge and debris from your radiators and pipework using a high-pressure cleaning machine. If you have multiple cold radiators, noisy pipes, or poor heat output, a flush could significantly improve performance.
