Benefits of Installing a New Boiler

Improved Energy Efficiency
Modern condensing boilers are significantly more efficient than older models. Increased efficiency means lower fuel consumption and reduced heating bills throughout the year.

Reduced Risk of Breakdowns
Older boilers often require frequent repairs. Replacing your system before it fails can help avoid unexpected breakdowns and emergency repair costs during the winter months.

Better Use of Space
Many modern boilers are compact and wall mounted, making them ideal for kitchen cupboards or smaller utility areas. Upgrading your system can create more usable space within your home.

Increased Safety
Gas appliances must always be installed and maintained by a Gas Safe registered engineer. Older boilers that are poorly maintained can pose safety risks, including carbon monoxide leaks.

Environmentally Friendly Heating
New boilers are designed to operate efficiently and produce fewer emissions. Improved efficiency means less wasted energy and a lower environmental impact.

Boiler Installation FAQs in Brentwood

Thinking about a new boiler for your Brentwood home? These are the questions our local engineers hear most often. If yours isn't here, give us a call and we'll talk it through.

How much does a new boiler cost in Brentwood?

A like-for-like combi swap starts from around £2,000, while system boiler replacements and combi conversions cost more because of the extra work involved. The final price depends on the boiler, flue and pipework, so we give you a fixed quote after a free survey.

Do I need a new boiler or can mine be repaired?

We always try to repair first using like-for-like parts, and sometimes a fault can even be fixed with a reset over the phone. If your boiler is over 10 years old, breaking down regularly or needs expensive parts, replacing it is usually better value in the long run, and we'll give you an honest recommendation either way.

What are the different types of boiler?

Combi boilers heat water on demand and suit smaller homes with one or two bathrooms. System boilers use a hot water cylinder and suit larger homes with several bathrooms. Regular boilers use a cylinder and loft tanks, and suit older homes or those with low mains water pressure.

Do your boilers come with a warranty?

Yes. As a Vaillant Advance installer and Ideal Heating MAX accredited installer, we can offer extended manufacturer warranties of up to [X] years on qualifying boilers. We register the warranty for you, and an annual service keeps it valid.

Can you install an LPG boiler if my home isn't on mains gas?

Yes. We're qualified to install and service LPG boilers and appliances, which is ideal for homes in the villages around Brentwood that aren't connected to the gas network.

How long does a boiler installation take?

A straightforward combi swap is usually done in one day. Converting to a combi or moving the boiler to a new location typically takes two to three days.
