Reliable New Boiler Installation in Ely, Soham & Newmarket
Is your boiler past its best – rising bills, lukewarm radiators, or a unit older than 10 years? A new boiler installation from CB7 Oil & Gas restores reliable heating and hot water while cutting energy waste. We install modern gas and oil boilers across Ely, Soham, Newmarket, Wicken, Burwell, Littleport and surrounding villages, with every job carried out by Gas Safe and OFTEC registered engineers.
Owner Christian Hough personally surveys your home before recommending anything. We size the boiler correctly for your property, explain your options in plain English, and leave the work area spotless. No pressure, no jargon just honest advice and a system built to last.
How Much Does A New Boiler Installation Cost?
Most replacement installations fall between £1,000 and £3,000 depending on the boiler type, brand and complexity of the pipework. A straightforward like-for-like gas combi swap sits at the lower end; an oil system boiler or a full system conversion costs more. You’ll always get a clear, fixed quote within 24 hours never an open-ended estimate.
Worried about upfront cost? Ask us about the Government Boiler Upgrade Scheme, which offers grants toward low-carbon heating, and we’ll tell you honestly whether it suits your home.

With over 100 five-star reviews, local homeowners trust us for clear communication and tidy, skilled workmanship. We handle the whole process from advice to aftercare so you’re never left guessing. Whether you need a new combi boiler in Ely or an oil boiler installation in Soham, we make it simple and stress-free.
Common Questions:
How long does a new boiler installation take?
A like-for-like swap is usually completed in one day. Moving the boiler’s location or converting from a conventional to a combi system can take two to three days.
Should I replace my boiler or repair it?
If your boiler is over 12 years old, breaking down repeatedly, or costing a lot in fuel, replacement is normally the cheaper choice long-term. We’ll give you a straight answer after the survey rather than pushing a sale.
Do you install oil boilers as well as gas?
Yes. Christian is an OFTEC-certified oil-boiler technician, so we install and commission both oil and gas systems, ideal for rural homes around Wicken, Isleham and Fordham that are off the gas grid.
Can you remove my old boiler and oil tank?
Yes, we safely decommission and remove old boilers and can advise on oil tank replacement where needed, disposing of everything responsibly.
