💬 Questions about boiler replacement in Blackheath
Do I need a Gas Safe registered engineer?
Gas boiler work must be done by a suitably qualified Gas Safe registered engineer. Check their current registration and appliance qualifications on the Gas Safe Register before agreeing to the work.
How long does a boiler installation take in Blackheath?
A like-for-like swap is usually one day. Moving the boiler or changing the type can take two or three.
Should I get a new boiler or repair mine?
Ask an engineer to compare the fault, repair cost, parts availability and condition with the full replacement price. Age alone does not establish that replacement will save money or pay for itself.
What is included in a new boiler installation quote?
Compare the exact boiler model, controls, flue work, system clean, disposal, commissioning, VAT and paperwork. Ask whether pipe upgrades, moving the boiler or removing a cylinder cost extra.
Does a combi boiler replacement cost less than a conversion?
A like-for-like replacement in the same position usually needs less work than changing boiler type or location. Compare written specifications rather than the boiler-only price; a conversion can involve extra pipework and cylinder work.
