It's the same story in half the terraces in London: radiators that stay cold at the bottom, a boiler that sulks every winter, and pipework nobody has looked at in decades. Heating in London means working around old layouts, tight access and houses that were never built for what's in them now. We sort the cause, not just the symptom.

Central Heating Installation and Replacement
Old systems in period houses
London's older homes rarely have tidy pipework. In the Victorian and Edwardian terraces around Clapham and Wandsworth, we often find systems that have been added to, patched and altered over decades. Replacing one means reading what's already there before anything new goes in.
What a full installation involves
It's three parts: the boiler, the pipework and the radiators. We don't fit a system to a brochure. The size of the property, the number of rooms and the existing layout decide what goes in. You'll get that in writing as a price before any work starts.
Flats, mansion blocks and basements
Mansion blocks in Kensington and Hammersmith bring their own limits on routes and access. Basements add another layer. Wandsworth says building-regulations approval is always required for basement extensions, so heating in those spaces needs proper checking. We plan for that early.

Radiator, Thermostat and Heating Pump Repairs in London
Cold spots and leaking valves
A radiator that's hot at the top and cold at the bottom is a familiar sight. Sometimes it's trapped air and a quick bleed. Sometimes it's sludge. A weeping valve is a different job again. We sort out which it is before anything gets replaced.
Thermostats and pumps
If the boiler fires but the rooms stay cold, look at the thermostat and the pump. A failing pump can leave a house with a working boiler and no heat. Controls that don't talk to the boiler cause the same complaint. Both are repairs, not replacements, more often than people expect.
Covering the central boroughs
Whether you are in London or City of Westminster, you can come to us for heating in City of Westminster just as easily. Around the Royal Parks, from Hyde Park to St James's Park, the streets are tight and access takes planning. We plan it.

Gas Work Rules and Landlord Checks
What gas work means for your home
Gas work is regulated, and rightly. We explain the work and the rules, so you know what's being done and why. Nothing is left vague.
Landlords and the annual check
If you let out a property, you have a yearly duty to have gas appliances checked. The Health and Safety Executive (HSE) sets that out. It covers appliances, flues and the safety of what's installed. We can talk it through when you ring.
Underfloor heating
Wet and electric underfloor systems are part of what we do. Fitting one in an existing home means looking hard at floor build-up and access. That's a conversation to have before the quote.
Boiler Repairs and Fault Diagnosis
Common faults
No heat. No hot water. Pressure that keeps dropping. Odd noises from the boiler. They're common faults, and each points somewhere different. A repair visit starts with finding the cause, not guessing at parts.
Repair or replace?
Do you always need a new boiler? No. Plenty of faults are repairable, and we'll tell you honestly when they aren't. You'll see the reasoning in the written price.
Part of the wider picture
A boiler fault is often a symptom of something elsewhere in the system. That's why our heating work looks at the whole circuit. Fix one part and ignore the rest, and you'll be calling again.
Central Heating Maintenance and Servicing
Annual servicing
A yearly service catches small problems before they turn into cold mornings. It's routine, it's quick to arrange, and it's cheaper than ignoring it. We cover the boiler and the system around it.
Power flushing
Sludge builds up in older systems. It clogs radiators and strains pumps. A power flush clears it, and it's worth doing when radiators stay cold at the bottom. We'll say plainly if it isn't needed.
Across London
If you're searching for a heating specialist near you in Islington or Richmond, we cover both. Whether you are in London or Islington, you can come to us for heating in Islington. We also cover an air conditioning in London job for homes and small businesses. Curious how long homes have had this at all? There's a short read on when did the UK have central heating.

Heating in London FAQs
How much does heating cost per month in London?
It depends on the property, the system and how you use it, so we won't quote a figure that could mislead you. What we can price is the work: describe the job to us and you'll get a written price before anything starts.
Should my boiler be repaired or replaced?
Many faults are repairable. A repair visit starts by finding the cause. If replacement is the sensible route, we'll say so. Either way, you'll see the work described in the written price first.
Can you work on heating in a Victorian terrace?
Yes. Victorian and Edwardian terraces across London often have pipework that's been altered many times. We read what's there first, then plan the work around it. That's how we keep surprises down.
Does heating work differ in a basement or mansion block?
It can. Wandsworth says building-regulations approval is always required for basement extensions, and Kensington and Chelsea sets limits on basement works. Mansion blocks bring access limits too. We plan for these before quoting.
Do you cover areas like Islington and Westminster?
Yes. We cover Greater London and the towns around it, including Westminster, Islington, Croydon, Harrow, Romford, Sutton and Wimbledon. Ring and tell us where the job is.
Do you fit underfloor heating?
Yes, wet and electric. Fitting in an existing home depends on the floor build-up and access. Tell us about the room, and we'll put a written price together.
