When a boiler becomes unreliable, choosing its replacement can feel more complicated than it needs to be. At RCB Heating & Cooling, we provide professional boiler installation in Epsom, helping homeowners choose a system that suits their property, hot-water needs and budget. We manage everything from the first survey to the final checks.

We install modern boilers in houses, flats, extensions and newly renovated properties. Before suggesting a model, we assess the size of your home, its water pressure, the number of radiators and how much hot water your household normally uses.

If your current boiler is breaking down regularly or becoming costly to run, replacement may be more sensible than another repair. Our boiler replacement service in Epsom includes removing the existing unit, fitting the new boiler and testing the complete heating system.

A combi boiler supplies heating and hot water from one compact unit, removing the need for a separate hot-water cylinder. This can be particularly useful in smaller homes and flats where storage space matters. We’ll check the incoming water pressure and demand before deciding whether a combi is appropriate.

Older boilers can waste energy even when they appear to be working normally. We install efficient modern systems and compatible heating controls, giving you better control over temperatures and schedules while helping to reduce unnecessary energy use.
A good installation starts with an accurate assessment rather than simply replacing one appliance with another. Epsom has a broad mix of properties, including older homes around Epsom Common, family houses towards West Ewell and newer developments closer to the town centre.
Their heating requirements can be very different.
We inspect the existing boiler, pipework, radiators and controls before explaining the most practical options. Once you’re happy with our recommendation, we’ll arrange the work, protect the areas around the installation and keep disruption under control.
After fitting the boiler, we test the heating and hot-water system carefully. We’ll then explain the controls in plain English so that you know how to operate the system efficiently.
We can also help with boiler repair in Epsom when replacement isn’t necessary. Booking an annual boiler service in Epsom can identify wear, operating issues and developing faults before they turn into more disruptive problems.
RCB Heating & Cooling is a Which? Trusted Trader with more than 3,600 completed projects and excellent feedback from customers on Google.
We regularly work throughout Epsom and the surrounding Surrey area, so we understand the practical challenges presented by local properties. That might mean working carefully around original features in an older house, dealing with restricted access in a flat or improving a heating system that has been altered several times over the years.
Our customers value honest advice, reliable appointments and tidy workmanship. We explain what’s required before starting and won’t recommend a larger or more expensive boiler than your home needs.
Areas We Cover
From our base in Sutton, we work throughout Epsom and neighbouring parts of Surrey. Our regular coverage includes Ewell, Stoneleigh, Chessington, Ashtead, Banstead, Cheam and Worcester Park, as well as the residential areas surrounding Epsom Downs and Epsom Common.

We visit your property, inspect the current system and discuss your heating and hot-water requirements.

You’ll receive advice on suitable boiler types, positioning and controls based on how your home is actually used.

We provide a straightforward quotation setting out the agreed installation work and costs.

Our team removes the old boiler where required, installs the new system and works carefully inside your home.

We test the boiler, heating and hot water before explaining the new controls and answering any remaining questions.

A straightforward replacement will often be completed within one day. Changing the boiler type or moving it to another part of the property can take longer.
Frequent faults, rising running costs, uneven heating and difficulty sourcing parts may suggest that replacement is becoming the more practical option.
Often, yes, but it depends on the property’s water pressure and hot-water demand. We’ll confirm whether a combi is suitable during the survey.
Boiler size depends on several factors, including the number of radiators, bathrooms and people living in the property. We calculate this before recommending a unit.
Yes. We can investigate boiler faults and advise whether repair or replacement represents the better long-term choice.
A boiler should generally be serviced once a year. Regular servicing helps maintain dependable operation and may be required to keep the manufacturer’s warranty valid.
