Repair or Replace Your Boiler?
Repair or Replace Your Boiler?
Repair or replace? An honest assessment of your boiler in Kingston upon Thames and South West London — we would rather fix a good boiler than sell you a new one.
About this service
Repair or Replace Your Boiler? in South West London, done properly the first time
The questions that matter are: how old is it, how efficient is it, are parts still available, how many faults has it had in the last two years, and how much is this particular repair against the cost of replacing.
As a rough guide, a boiler under eight years old with its first significant fault and available parts is almost always worth repairing. A boiler past twelve years with repeated faults, obsolete parts or a failed heat exchanger rarely is.
We diagnose first and give you both numbers — repair cost and replacement cost — then let you decide. No engineer of ours is incentivised to condemn a boiler.
