Common Boiler Problems

Reasons Kensington & Chelsea Homeowners Replace Their Boiler

From ageing boilers in Notting Hill’s period townhouses to inefficient units in South Kensington’s mansion flats, here are the most common reasons our customers across the borough call us in for a new boiler.

 

Boiler is over 10–15 years old

Older boilers become less efficient and more prone to breakdown over time. Many properties across the borough's period housing stock are still running boilers well past their expected working life.

Frequent breakdowns or repairs

If a boiler needs repairing more than once or twice a year, replacement is often more cost-effective than continuing to fix an ageing unit — particularly for parts that are becoming harder to source.

Rising energy bills

An inefficient older boiler can use significantly more gas than a modern condensing combi to produce the same amount of heat, especially in the larger townhouses around Holland Park and Chelsea.

Insufficient hot water or pressure

Larger properties in Kensington and Chelsea with multiple bathrooms sometimes outgrow an older combi boiler's capacity, leading to poor pressure or hot water running out.

Local Knowledge

Boiler Installation for Every Kensington & Chelsea Property Type

Kensington and Chelsea spans everything from the grand stucco terraces of Notting Hill and Holland Park to the mansion blocks of South Kensington and the mixed housing of North Kensington and Earls Court. Our engineers are experienced with every property type in the borough.

 

Stucco terraces & townhouses — Notting Hill & Holland Park

These larger period properties often suit a system boiler with a hot water cylinder, sized to cope with multiple bathrooms and higher simultaneous demand, while respecting original features during installation.

 

Mansion blocks — South Kensington & Chelsea

Mansion block flats typically call for a compact combi boiler fitted within a kitchen cupboard, with flue routing agreed in advance with the building’s managing agent where required.

 

Mixed terraces & flats — Earls Court & North Kensington

These converted houses and flats typically suit a compact combi boiler sized to a smaller footprint, often installed within a kitchen cupboard or utility space.

Garden square houses — Kensington & Chelsea Riverside

Larger houses around the borough’s garden squares and riverside often benefit from a system boiler and cylinder to serve multiple bathrooms across several floors.

Our 16-year-old boiler in Notting Hill finally gave up. New combi fitted in a day, explained the controls clearly and the fixed price didn’t change from the original quote.
