Our Boiler Services in Ashtead

new boiler installation

New Boiler Installation

Whether you’re renovating, extending or fitting heating in a newly built property, we can design and install a suitable boiler system. We consider the building’s size, insulation, number of radiators and expected hot-water use before recommending the right output.

boiler replacement

Boiler Replacement Services

If an older boiler is unreliable, inefficient or no longer economical to maintain, we can replace it with a modern alternative. Our boiler replacement service in Ashtead includes removing the existing appliance, completing the installation and checking the heating and hot water thoroughly.

combi boilers

Combi Boiler Installation

Combi boilers heat water directly from the mains and don’t require a separate storage cylinder. This makes them a space-saving option for many homes. Before recommending one, we’ll check the property’s water pressure and whether it can meet your household’s usual demand.

Energy-Efficient Boiler Upgrades

A modern boiler and more accurate controls can help prevent wasted heat. We can upgrade outdated systems and install suitable controls that allow you to set temperatures and schedules around your routine rather than heating an empty property unnecessarily.

Our Boiler Installation Service in Ashtead

Ashtead has an interesting mix of older cottages, inter-war houses and larger family homes, with newer properties dotted between them. The heating requirements can vary significantly, especially where a house has been extended or its system altered over time.

We start by inspecting the existing boiler, accessible pipework, radiators and controls. We’ll also discuss how your household uses heating and hot water. A family home with more than one bathroom, for instance, may need a different arrangement from a smaller property occupied by one or two people.

Once we’ve agreed on the best approach, we arrange the work for a convenient date and take care to protect your home during the installation. The new system is tested before we leave, and we’ll show you how to operate its controls properly.

We also provide boiler repair in Ashtead when a fault can be resolved without replacing the appliance. An annual boiler service in Ashtead can help identify developing problems and keep your system operating dependably.

Why Choose RCB Heating & Cooling?

RCB Heating & Cooling is recognised as a Which? Trusted Trader. We’ve completed more than 3,600 projects and have earned excellent reviews from customers on Google.

Our team works throughout Ashtead and the wider Surrey area, so we’re familiar with the heating arrangements found in local properties. Older systems don’t always follow the most obvious route, and extensions can place extra demand on boilers that were originally selected for a smaller house. We take these details into account before recommending any work.

Customers choose us for practical advice, clear communication and workmanship that respects their property. We’ll explain your options without unnecessary technical language and give you the information needed to make a sensible decision.

Our Boiler Installation process

1. Surveying Your Heating System

We inspect the boiler, radiators, controls and relevant pipework while discussing your current concerns.

2. Choosing the Right Boiler

We identify suitable systems based on the property and your heating and hot-water needs.

3. Providing a Clear Quotation

You’ll receive an itemised quotation explaining the agreed work and costs.

4. Completing the Installation

We remove the old appliance where required, install the new boiler and keep disruption to a minimum.

5. Testing and Handover

We check the full system, explain the controls and answer your questions before completing the job.

Frequently Asked Question

How do I know whether to repair or replace my boiler?

The decision depends on its age, general condition, repair history and the cost of the fault. We’ll inspect it and explain both options where appropriate.

How long does boiler replacement take?

A standard replacement can often be completed in one day. Relocating the boiler or converting the system may require more time.

What type of boiler should I choose?

That depends on the property’s size, water pressure and hot-water demand. We recommend a system only after assessing these points.

Can a boiler be moved to another room?

Usually, although new pipework and a suitable flue route may be required. We can assess potential locations during the survey.

Will you dispose of the old boiler?

Yes. Removal and responsible disposal of the existing boiler can be included in the installation.

Why is annual boiler servicing important?

A yearly service checks the appliance’s operation, identifies signs of wear and may be necessary to maintain its manufacturer warranty.
