Boiler Replacement
Across Coventry & Warwickshire
Your old boiler is costing you hundreds per year in wasted energy. We replace it with a modern A-rated unit — fixed price, fitted in a day, with up to 12 years of manufacturer warranty.
Service Overview
What You Need to Know
What Is This Service?
A boiler replacement involves removing your existing boiler and fitting a new, energy-efficient unit in its place. This includes all pipework connections, flue modifications, system flushing, and commissioning. We handle like-for-like swaps and system conversions.
Who Is It For?
Homeowners with boilers over 10 years old, anyone facing repeated breakdowns, landlords needing compliant heating for rental properties, and anyone whose current boiler is no longer economical to repair.
When Do You Need It?
When repair costs approach 50% of a new boiler's price, when your boiler is over 10-12 years old, when energy bills keep climbing, or when your engineer advises that parts are no longer available.
Why Use a Professional?
A boiler replacement must be carried out by a Gas Safe registered engineer. An improperly installed boiler is a carbon monoxide risk, voids insurance, and fails to deliver the efficiency savings you're paying for.
Don't Ignore the Signs
The True Cost of Keeping an Old Boiler
- !Wasted energy — a 15-year-old G-rated boiler wastes up to 40% of the gas it burns. That's over £400 per year in wasted fuel on average.
- !Repair spiral — once major components start failing, you're paying £150-300 per repair on a boiler that will fail again within months.
- !No parts available — manufacturers discontinue parts for older models, meaning your next breakdown could be the last.
- !Carbon monoxide risk — ageing heat exchangers develop micro-cracks that leak odourless, deadly carbon monoxide into your home.
- !Insurance exposure — some home insurance policies won't pay heating-related claims if your boiler hasn't been serviced or is beyond its serviceable life.

In Detail
When and Why to Replace Your Boiler
The average boiler lifespan is 10-15 years. After this point, efficiency drops significantly — even a well-maintained boiler will lose 10-15% of its original efficiency rating. For a boiler that was 85% efficient when new, that means it's now operating at 70-75%, wasting a quarter of your gas spend.
Modern condensing boilers achieve 92-94% efficiency under typical operating conditions. The difference between a 70% efficient old boiler and a 93% efficient new one amounts to £300-450 in annual gas savings for an average three-bedroom home in Nuneaton or Coventry.
We replace all types of domestic boilers. Combi-to-combi swaps are the simplest, typically completed in 5-7 hours. Converting from a regular (conventional) boiler to a combi involves removing the hot water cylinder and cold water tanks, freeing up space in your airing cupboard and loft.
System boiler replacements suit larger properties with multiple bathrooms. We install sealed-system cylinders from Megaflo and other manufacturers, providing mains-pressure hot water to every outlet without the limitations of a gravity-fed system.
Every replacement across Nuneaton, Bedworth, Coventry, Leamington, Solihull, Tamworth, Atherstone, and Warwick includes a full system flush with chemical cleaner, fresh inhibitor, and a magnetic filter. This protects your new boiler from existing system sludge — the leading cause of premature boiler failure.
