WHY LONDONERS UPGRADE

Reasons Londoners Choose a New Boiler

Whether it’s an ageing boiler or a full system upgrade, these are the reasons we hear most often, right across the city.

Old or Failing Boiler

Replacing a boiler that’s frequently breaking down, losing pressure, or reaching the end of its expected life.

High Energy Bills

Modern condensing boilers run significantly more efficiently than older models, cutting running costs.

Moving to a New Property

Fitting a new boiler as part of moving in or renovating, sized correctly for the property.

 

Switching System Type

Moving from a conventional or system boiler to a combi, or vice versa, to suit changing needs.

CAPABILITY

Every Boiler Type, Fitted

The right boiler depends on your property size, hot water demand, and existing system.

Combi Boiler

Heats water on demand with no separate tank needed — the most popular choice for flats and smaller households across London.

Most popular

System Boiler

Works with a hot water cylinder, ideal for homes with higher hot water demand or multiple bathrooms.

Best for multiple bathrooms

Conventional Boiler

Traditional setup with a cold water tank and hot water cylinder, often used when replacing like-for-like in older properties.

Like-for-like replacement
