Choosing the right boiler for your home
Combi boilers. Combi boilers heat water directly from the mains, on demand, with no need for a hot water cylinder or loft tank. They're a popular choice for smaller homes with one bathroom, and take up less space.
System boilers. System boilers work with a hot water cylinder, so they can supply multiple bathrooms with strong pressure at once. Most of the components are built into the boiler itself, keeping installation tidy.
Regular (conventional) boilers. Regular boilers use both a hot water cylinder and a cold water tank, usually in the loft. They suit homes that already have this setup, or larger properties with higher hot water demand.

Frequently Asked Questions
How much does a new boiler cost in Dunstable?
It depends on the boiler, your property and any extra work needed, so we don't publish a fixed price — get in touch for a free, no-obligation quote based on your home.
How long does a boiler installation take?
A straightforward like-for-like combi swap can often be done in a single day. Installations involving a change of boiler type or extra pipework may take longer — we'll confirm the likely timescale when we quote.
Should I repair or replace my boiler?
It depends on the boiler's age, how often it's breaking down, and the cost of repeated repairs versus a new system. We'll always give you an honest recommendation rather than push a replacement you don't need.
Are you Gas Safe registered?
Yes — Reg No. 945203. All installation work is carried out and certified by a Gas Safe registered engineer.
Will you handle Building Regulations notification?
Yes. As a Gas Safe registered installer, we notify Building Control on your behalf when we install a new boiler, so you don't need to arrange this separately.
Do you install boilers from all manufacturers?
We work with a range of leading boiler manufacturers and will help you choose a model that suits your home and budget — ask us for our recommendation when you get in touch.
