Radiator Installation & Replacement London
Professional radiator installation and replacement across London — new radiator fitting, radiator upgrades, valve replacement and central heating radiator installation, with fixed pricing from £180.
Radiator Installation London
Whether you need one radiator fitted in a newly built room, a full house of radiators replaced, or a single ageing radiator swapped for something that actually heats the room properly, we handle radiator installation and radiator replacement as a complete, fixed-price service across London — separately from boiler work, and without needing a full central heating overhaul.
Radiator installation in London starts from £180 for a like-for-like replacement, fully fitted with new brackets, valves reconnected, and a complete system test. New radiator points, where no radiator currently exists, start from £280 since new pipework is involved.

Radiator Replacement London
Replacement makes sense once a radiator is past the point of being worth repairing. The most common signs: visible corrosion or rust staining, repeated leaks from the same joint, a radiator that stays cold even after bleeding, or simply a style change during a room renovation. Replacing a radiator doesn't touch the rest of your central heating system — your boiler, other radiators and existing controls carry on exactly as before.
We also handle radiator upgrades during renovations — swapping a dated panel radiator for a vertical, column or designer style without changing anything else about how your heating works.

Radiator Installation for London Homes and Flats
We fit and replace radiators across houses, flats, maisonettes and rental properties throughout London. For landlords and letting agents, radiator replacement is often bundled with a wider property refresh between tenancies — we can quote for single units or a full property at once. For homeowners mid-renovation, we coordinate radiator style changes around decorating timelines so the room isn't out of action longer than necessary.
Radiator Installation Across London
We cover North London, South London, East London, West London and Central London, including the boroughs and areas we install boilers and central heating in every week.
Common Questions
How much does radiator installation cost in London?
Radiator installation in London starts from £180 for a straightforward like-for-like replacement, rising to £280 or more for installing a radiator where none currently exists, since that involves new pipework.
How much does it cost to replace a radiator?
Radiator replacement, using your existing pipework and position, starts from £180 including removal, brackets and reconnection. This is the most common and most affordable type of radiator job.
How long does radiator installation take?
A single radiator replacement usually takes 1 to 2 hours. Installing a radiator where none existed before, requiring new pipework, typically takes half a day.
Can you replace just one radiator?
Yes. Replacing a single radiator in an otherwise fine central heating system is one of our most common jobs. We isolate just that part of the system.
Can you install a larger radiator?
Yes. If a room has always felt under-heated, upgrading to a larger radiator during replacement is common and often solves the problem without any changes to your boiler.
Can you install a vertical or designer radiator?
Yes. We fit vertical, designer, column and towel radiators as well as standard panel radiators, matching output to the room regardless of style.
Do you supply radiators as well as install them?
Yes. We supply and fit radiators as a complete package, or fit a radiator you've already purchased if you prefer a specific style or brand.
Do radiator valves need replacing?
Not always. If your existing TRV and lockshield valves are in good working order, they can usually be reconnected to a new radiator. We replace them as standard when they're worn, seized, or an outdated type.
Can you install a radiator without replacing the boiler?
Yes. Radiator installation and replacement is entirely independent of your boiler. Your existing boiler will heat a new or replaced radiator exactly as it heated the old one, as long as it has enough overall capacity.
Do you drain the heating system when replacing a radiator?
Usually only the section of pipework feeding that radiator needs isolating, not the whole system. For some older systems without isolation valves already fitted, a partial drain may be required, which we'll confirm before starting work.
How do I know what size radiator I need?
Radiator size depends on the room's floor area, ceiling height, window size and insulation level, not a fixed rule of thumb. We size this correctly during your quote so the room heats properly without an oversized or underpowered radiator.
