Combi vs system boilers
A combi boiler heats water on demand with no tank required — a good fit for flats and smaller households. A system boiler works with a hot water cylinder, better suited to larger homes with multiple bathrooms. We'll recommend the right fit based on your property and usage, not the most expensive option.
What's included
- Removal and disposal of the old boiler
- Installation of the new boiler and any required pipework changes
- System flush where needed
- Gas Safe certification and building control notification

Common questions
How long does a boiler installation take?
A like-for-like combi boiler swap is usually a single day. Switching boiler type or relocating it can take 1–2 days.
Do you handle the paperwork?
Yes, we register the installation with Gas Safe and notify building control as required — you don't need to do anything yourself.
