What is a combi boiler?

A combi (or combination) boiler is a high-efficiency water heater and a central heating unit combined into a single compact system. Unlike traditional systems, a combi boiler doesn’t store hot water; instead, it heats water directly from the mains when you turn on a tap, ensuring instant hot water delivery.

How does a combi boiler work?

The combi boiler operates by taking cold water directly from the mains supply, heating it, and then delivering it to taps and radiators throughout your home. When you turn on a hot water tap, the boiler detects the flow, ignites the burner, and water is heated instantly. For central heating, the boiler works similarly, heating water that is circulated through radiators or underfloor heating systems.

Benefits of a combi boiler installation


Combi boilers are compact, eliminating the need for a separate hot water cylinder or cold-water storage tank. This is especially beneficial for homes with limited space, allowing for more room utilization


Combi boilers heat water on demand, ensuring no energy is wasted on heating unused water. This direct heating method can significantly reduce energy bills


With reduced energy consumption and no need for a separate water tank, homeowners often notice a decrease in utility bills, making combi boilers a financially smart choice

Instant hot water

Say goodbye to waiting for water to heat up. With a combi boiler, hot water is available immediately, providing convenience, especially during colder months


With no storage tank, the risk of water leaks or tank bursts is eliminated. Plus, modern combi boilers come with safety features that prevent gas leaks and other potential hazards

Having a new boiler installed doesn't need to be complicated, we're here to help make things simple, quick and affordable. Take a look at our most frequently asked questions to find the answers to your boiler-related queries.

How quickly can you install a new boiler in my home?

We understand that when you need a new boiler its usually due to a breakdown or loss of heating and hot water. Which is why we always aim to install from tomorrow! Fill out our remote survey to find your tailored quote, connecting you to the best boiler options for your home.

What can I expect on installation day?

Our engineers will arrive in the morning of your scheduled appointment with all the necessary tools and equipment required to complete your new boiler installation. Our experienced, vetted engineers will carry out your installation as quickly and smoothly as possible. However, we advise you to expect most of the day to be blocked out for the job to be completed.

We kindly ask you to make the installation point accessible for our engineers, and they will in turn protect the areas they work in and clean up after themselves.

Can my boiler be moved elsewhere in my home?

Yes, whether you'd prefer to move your boiler to a bedroom, into a cupboard or into the kitchen, our installation experts are able to relocate the boiler and it's pipework to suit you.

Will the installer flush my system?

Our installers will provide a standard power flush when your new boiler is installed. This will help remove rust and debris from inside your system – cleaning your pipes and radiators – which will help your new boiler operate more efficiently.

What happens to my old boiler/ water tank?

Once your new boiler has been successfully installed our engineer will take your old boiler and any other additional pipe work or water tanks that are no longer necessary for them to be properly discarded/ recycled.
