From ageing boilers in period buildings to compact flats needing space-saving solutions, these are the most common reasons Westminster residents contact us.
Boilers over 10–15 years old, common in many Mayfair and Marylebone conversions, become increasingly inefficient and prone to breakdown, often at the worst possible time.
Compact Soho and Covent Garden flats often need a space-saving combi boiler and careful flue routing to fit within a small kitchen or utility cupboard.
Once a boiler starts needing repeat repairs, the cost of ongoing call-outs often exceeds what a new, more reliable boiler would have cost over the same period.
A complete boiler failure leaves a property without hot water and heating, an urgent issue we treat as a priority across all Westminster postcodes.
A properly sized, correctly installed boiler with full certification, not just a swap of the old for the new.
We assess your Westminster property's hot water demand and heating requirements, along with any space or conservation constraints, to recommend the right boiler.
The existing boiler is safely disconnected and removed, with any associated pipework or flue made safe and cleared.
The new boiler is installed with a magnetic filter fitted as standard, the system flushed, and the flue routed and terminated to current building regulations.
The installation is tested, a Gas Safe certificate issued, and the boiler registered with the manufacturer to activate your warranty, along with full Benchmark documentation.
A properly specified new boiler pays back in efficiency, reliability and peace of mind.
Modern condensing boilers are significantly more efficient than older models, particularly boilers over 10 years old still common across Westminster's period housing stock.
A correctly installed new boiler comes with a manufacturer warranty of up to 10 years, giving genuine peace of mind against unexpected breakdowns.
Replacing an ageing or undersized boiler resolves inconsistent hot water pressure and slow heat-up times common in older Westminster systems.
A correctly sized combi boiler can free up valuable cupboard space in the compact flats common across Soho and Fitzrovia.
Cost depends on boiler type, output size and whether the flue or pipework needs relocating. All prices confirmed before we attend — no call-out charge.

Fast site visits and reliable scheduling across all Westminster postcodes, from Mayfair to Pimlico and Marylebone.
Every installation is based on your property's actual hot water and heating demand, rather than defaulting to the same size as the old boiler.
A common consideration across Mayfair, Belgravia and Marylebone, where flue position and external fittings need sympathetic handling.
The same fixed pricing applies whether you're in W1 Mayfair or SW1 Pimlico — no zone uplift, no congestion charge add-on, no extras added after the fact.
As an accredited Worcester Bosch installer, we can offer extended manufacturer warranties beyond the standard cover.
Every installation is Gas Safe certified with Benchmark documentation completed, protecting your warranty and any future property sale.
Our boiler installers cover the whole Westminster area — fixed pricing and same availability across every postcode, no area surcharges.

“Listed townhouse in Mayfair, worried about flue placement affecting the front facade. Routed discreetly to the rear elevation instead, explained the reasoning clearly and the finished job looks seamless.”
“Old combi in our Soho flat was on its last legs, tiny cupboard to work with. Fitted a properly sized replacement without any issue, freed up more space than the old one took.”
“Boiler had been repaired three times in a year in our Pimlico flat. Replaced with a new combi, properly sized for the property, and the whole job including certification was done in a day.”

Yes. Safe removal and disposal of your existing boiler is included in every installation price, along with any associated redundant pipework.
