If your boiler is no longer heating the house properly, needs frequent repairs or costs too much to run, replacement may be the practical next step. RCB Heating & Cooling provides professional boiler installation in Chessington, with careful system assessments, clear recommendations and tidy installation work tailored to the needs of your property.

We install complete boiler systems for new builds, extensions and major home renovations. Our team considers the property’s size, insulation, number of radiators and expected hot-water demand before specifying the boiler and controls.

An ageing boiler can become unreliable long before it stops working altogether. Our boiler replacement service in Chessington includes assessing the existing system, removing the old unit and fitting a modern alternative that’s correctly sized for the property.

Combi boilers provide heating and hot water directly from one appliance, without using a separate storage cylinder. This compact arrangement suits many Chessington homes, although we’ll first check that the water pressure and flow rate can support your household’s requirements.

Replacing an inefficient boiler can improve heating control and reduce the amount of energy wasted. We can install a modern system with compatible controls, allowing you to manage temperatures and schedules more accurately throughout the week.
Properties across Chessington range from traditional family homes around Hook and Chessington North to newer houses, flats and extended properties closer to Chessington South. A boiler that worked well before an extension was added may now struggle to heat the additional space.
That’s why we begin with a proper survey. We inspect the existing appliance, accessible pipework, radiators and controls while discussing how your household uses its heating and hot water. We also look at practical matters such as boiler location, access and the available flue route.
Once you’ve chosen the most suitable option, we arrange the installation and explain what to expect. We’ll protect the working area, complete the work carefully and carry out thorough checks before leaving. You’ll also be shown how to use the new boiler and controls.
Not every fault means a new appliance is required. We provide boiler repair in Chessington where a dependable repair is possible, along with an annual boiler service in Chessington to check the condition and operation of your system.
RCB Heating & Cooling is a Which? Trusted Trader with more than 3,600 completed projects and excellent reviews from customers on Google.
Our Sutton base allows us to work regularly across Chessington and the nearby Surrey area. We’ve dealt with heating systems in properties of many different ages, including homes where the pipework has been changed several times or where an extension has altered the original heating demand.
We believe customers should understand what they’re paying for. Our team explains the available options, provides a clear quotation and works with respect for your home. We won’t suggest replacing parts of the system without a practical reason.

A straightforward replacement can often be completed within one day. Moving the boiler or converting to a different system may require additional time.
The right choice depends on the property’s size, number of bathrooms, water pressure and hot-water demand. We’ll assess these factors during the survey.
Often, yes. However, we’ll need to check whether a combi can provide enough hot water for the household, particularly if you have more than one bathroom.
That depends on the boiler’s age, condition and repair history. We’ll explain whether a repair is likely to provide reasonable long-term value.
Not usually, provided they’re in suitable condition and deliver enough heat. We’ll identify any individual radiators or valves that need attention.
An annual service is recommended to check safe, dependable operation and may be required to maintain the manufacturer’s warranty.
