Locally, this is what comes up

Boiler installation in Wimbledon

  • Larger houses with two or more bathrooms likely to be in use at once
  • Properties where a combi was fitted on price and has never quite kept up
  • Installations sized on the radiator count and occupancy rather than on what was there before

The larger Wimbledon houses often have a vented cylinder that has already outlived several boilers. Before replacing the boiler, it is worth checking the cylinder’s condition and its coil, because a new boiler paired with a tired, slow cylinder still gives slow hot water. The choice is between keeping the vented setup with its loft tanks or moving to an unvented cylinder, which depends on the mains supply and where a larger cylinder could sit. The flats nearer the town centre are simpler and usually suit a combi. Period houses near the Common may be in a conservation area, so a new flue on a front or side wall facing the road needs checking with Merton’s planning team before the position is fixed. Most family houses up the hill have a drive, which makes the day easier, and the old boiler and cylinder can go straight out to the van.

Questions

Common questions

Do you cover Wimbledon?

We do. Wimbledon falls within Merton, covering the SW19, SW20 postcodes, and our engineers are out across Greater London from our Fulham office every day.

How do you decide what size boiler we need?

Radiator count, number of bathrooms and how many people actually live there — not the size of the old one, which may well have been wrong too. Oversized boilers cycle on and off and wear out early; undersized ones never keep up. It is worth getting right at the point of installation because it cannot be adjusted afterwards.

Do the radiators and pipework have to be replaced along with the boiler?

Not usually. What matters is the condition of the water inside the system. Older systems in big houses carry years of sludge, and fitting a new boiler onto that shortens its life. The system should be cleaned, dosed with inhibitor, and fitted with a filter as part of the installation. Radiators that stay cold at the bottom after cleaning may be worth replacing, and we point those out before quoting rather than afterwards.

What does it cost?

You will have a price for the work before an engineer starts. If something behind the wall changes the scope, we pause and talk it through with you rather than carrying on and billing you afterwards.
