Boiler Installation Services
The kind of building decides the job
London isn't one type of house. A Victorian terrace in Clapham, a converted villa in Richmond and a mansion block in Kensington each ask for a different boiler job. We've set this page out around that.
In an older terrace the old boiler often sits in a kitchen corner with a flue run that's been altered over the years. In a mansion block the flue route and the pipework in shared walls shape everything. In a modern flat the boiler is usually in a cupboard, and space is the whole question.
What we fit and where we work
We handle a new boiler for homes and small businesses across Greater London and the towns around it, including Westminster, Islington, Croydon, Harrow, Romford, Sutton and Wimbledon. You describe the job at no charge. A written price follows before any work starts.
Access around the Royal Parks
London has eight Royal Parks, including Hyde Park, Kensington Gardens and St James's Park, and dense streets sit all around them. Homes nearby can need careful access planning. We think about that before the day, not on it.

New Boiler Replacement
Swapping the old one out
Most boiler replacement jobs start the same way. The old boiler comes off, the new one goes on, and the pipework, flue and controls are checked against it. Some jobs are a straight swap. Others need the boiler moved, and that changes the work.
From London to City of Westminster, we're there when you need a boiler fitting. Stucco-fronted townhouses there often mean long pipe runs and tight routes for the flue.
Older homes and what turns up
Georgian and Victorian houses tend to have heating layouts that have grown in stages. Radiators have been added, pipes rerouted and valves replaced. A new boiler is the moment to look at all of it.
From London to Islington, we're there when you need boiler replacement as well. Conversions in that part of town often hide pipework behind later alterations.
Basements and flood risk
Basements need extra thought. The Greater London Authority says basement plumbing should account for possible sewer flooding. Wandsworth says building-regulations approval is always required for basement extensions. So a boiler going into a basement plant room gets planned properly. It isn't an afterthought.
Boiler Installation Process and Boiler Installation Costs
How the job runs
It starts with a conversation about your home and your heating. Then comes a look at what's there: the existing boiler, the radiators, the pipework and where the flue can go. Then we write it up.
The work itself follows a clear order. Drain down and disconnect the old boiler. Remove it. Fit the new one, connect the pipework and flue, then refill and commission it. Controls come last.
What affects the written price
We don't quote a figure before we know the job. The price depends on the boiler type, the flue route, any pipework changes and the controls you want. You'll get it in writing before anything starts.
Describing the job costs you nothing. Want to know what yours involves? Ask us. We'll tell you plainly.
Changes that sometimes come with it
Some homes need extra work alongside the boiler. That might be a magnetic filter, a chemical flush of the system or a different position for the unit. We say so up front, in the written price.

Gas Rules and Safety for a Boiler Installation in London
What the law says
The law requires anyone doing gas work to be competent, and anyone doing it as a business to be Gas Safe registered. HSE and Gas Safe Register advise using a registered engineer. That's the standard for any boiler installation.
Why the flue matters
A boiler is only safe if the flue is right. Position, clearances and sealing all count. In tight London properties, that's often the hardest part of the boiler installation.
Safety checks at handover
When the work's done, the boiler is tested and the controls are shown to you. You should leave knowing how it works and what to watch for. If something doesn't look right, say so.
Choosing the Right Boiler Type for London Homes
Combi boilers in flats and smaller houses
A combi heats water on demand and needs no tank. That suits flats and smaller houses where space is short. It's common in modern apartment developments around Stratford.
System and traditional boilers in bigger homes
Larger houses with several bathrooms often suit a system boiler with a cylinder. Older homes with tanks in the loft may still run a traditional setup. Whether yours stays or changes depends on the building.
Size and pipework
Which boiler size is right? It depends on how many radiators and bathrooms you have and how people in the home use hot water. We work that out on site, not from a chart.
Energy-Efficient Heating Systems
Controls that earn their place
A new boiler works best with decent controls. A wireless thermostat or smart controls let you heat when you need to. It's a small addition to the job and it's easy to fit alongside the boiler.
Looking after the system around it
An old system full of sludge can undermine a new boiler. Power flushing and a magnetic filter protect it. We'll tell you if your radiators suggest it's worth doing.
