Boiler help for London
Is 1 H Construction Limited Gas Safe registered?
This directory does not confirm registration. Anyone working on a gas boiler in the UK must be on the Gas Safe Register, so check it directly using the company name or the postcode (SE3 7DW) before booking, and ask to see the engineer's Gas Safe ID card on the day.
How often does a boiler need servicing?
Once a year for a gas boiler, ideally before winter. An annual service by a Gas Safe registered engineer keeps most manufacturer warranties valid, and for a rented home it is the landlord's legal duty (the CP12 gas safety record).
Can I see reviews for 1 H Construction Limited?
Not here. This is a register-based directory, not a review site. Look at independent review platforms, ask the engineer for recent local references, and confirm Gas Safe registration before any work starts.
What should I do if I can smell gas?
Turn the gas off at the meter, open windows, avoid light switches and naked flames, leave the property, and call the National Gas Emergency line on 0800 111 999. Do not wait for a routine appointment.
