Service area · London
Camden is a borough of period terraces, mansion blocks and conservation-dense streets. Hampstead, Primrose Hill, Belsize Park and Dartmouth Park are some of the most architecturally sensitive residential areas in London. Add Bloomsbury's Georgian squares and Kentish Town's mix of Victorian terraces and converted flats, and almost every job needs thinking about — not just quoting.
We do a lot of boiler work in Camden. Many of the mansion flats still run old system boilers with failing indirect cylinders, and the upgrade path — to a modern Viessmann or Worcester system boiler with an unvented cylinder — is genuinely transformational for hot water quality and running costs. Heat pumps are tougher here because of the conservation constraints, but we do install them where the siting works.
We know which conversations to have with Camden planning before starting work, and which don't need to happen at all. We quote properly. We show up when we said we would. And we respect the property — dust sheets everywhere, overshoes as standard, daily texts on how the work is progressing.

What we work on
Victorian and Georgian terraces across Hampstead, Primrose Hill, Belsize Park, Kentish Town and Camden Town. Mansion flats in Bloomsbury, Belsize Park and Highgate. Mews cottages in NW1 and NW3. A smaller number of 1960s-80s apartment buildings in Swiss Cottage and Chalk Farm. Highly protected stock around Fitzrovia and Bloomsbury.
What Camden homes ask for most
Boiler replacement is the most common Camden job — typically Viessmann system boilers with unvented cylinders in mansion flats, and combi boilers in single-family houses where space is tight. Air conditioning has grown steadily in top-floor bedrooms and home offices. Heat pumps are viable but site-specific; we'll tell you straight if your property is a fit or not.

01
Hampstead, Fitzrovia, Bloomsbury, Primrose Hill, Belsize Park, Dartmouth Park — most residential Camden sits in a conservation area. External plant and flue terminations need proper thought. We check designation before quoting.
02
Grade II and II* listings are common in Hampstead and Bloomsbury. Any intervention affecting character needs listed building consent. We have worked inside these properties before.
03
Permit-only parking across most of the borough, with paid bays around Camden Town, Hampstead and Belsize Park. Mansion block work always needs a conversation with the managing agent or porter. We schedule around that.

Replaced our old combi with a heat pump. Quiet, much cheaper to run, and the team left the plant room tidier than they found it.

Dulwich · Heat pump
We had three quotes for a new Viessmann boiler. Thermalwerk was not the cheapest, but they were the only ones who actually explained the sizing.

Islington · Boiler replacement
Two Daikin units fitted across an open-plan living space. Clean cable runs, properly commissioned, works brilliantly. Glad we waited for them.
