"A combi boiler swap" covers a wide range of actual jobs, and that's exactly why two quotes for what sounds like the same work can differ so much in London. The main things that move the price:
- Region — installer day rates vary a fair amount across the UK, and London and the wider London area is no exception.
- Property size — more bedrooms and bathrooms generally means a higher-output boiler and more pipework, which costs more.
- Fuel type — oil and LPG installs typically cost more than mains gas once unit cost and any tank/bunding work are factored in.
- Relocation or system change — moving the boiler to a new spot, or switching from a stored (system/regular) setup to combi, adds labour that a simple like-for-like swap doesn't need.
- Boiler brand and output tier — budget, mid-range and premium boilers carry a real price difference before labour is even added.
- Local property type — In a lot of London properties the boiler is squeezed into a kitchen cupboard or loft hatch, so access and flue routing can add labour time that a straightforward garage or utility-room swap elsewhere wouldn't need.
Boiler quotes for 'the same job' can differ by well over £1,000 once you factor in what each installer has actually included — and boilers aren't something most people can judge for themselves. That's what the free check below is for: comparing your actual property, fuel type and quoted price, so you can see where yours sits before you agree to anything.
Before you agree to spend thousands…
The full £1.99 Quote Protection Check runs through your specific boiler quote line by line, including:
- Whether the price you've been quoted is realistic for a properly certified installation, or missing something that shows up as an 'extra' later
- What to ask before you sign, so you're not the one who discovers a gap once the old boiler's already out
- What you're entitled to — and what to check — before any money changes hands
Think of it like insurance on a purchase you can't take back: a boiler keeps your home running through winter. £1.99 to make sure the quote actually stacks up is a lot cheaper than finding out it doesn't, mid-installation.

London boiler quote FAQs
How much does a boiler replacement cost in London in 2026?
A like-for-like combi boiler replacement in London typically costs between roughly £2,500 and £5,000, depending on property size, boiler output and exactly where in London you are. Relocating the boiler, switching fuel type, or changing from a stored system to combi adds to that.
Is my boiler quote too expensive?
It depends on the boiler's output, brand, your property size, and what labour and extras (flue work, controls, disposal, making good) are included. ProtectMyQuote compares your specific quote against typical 2026 UK trade prices for your job and London so you can see where it sits.
Do I need a Gas Safe registered engineer in London?
Yes, for any gas boiler work. You can check any engineer's registration number for free at gassaferegister.co.uk before agreeing to anything. Oil-fired systems need an OFTEC-registered technician instead.
Does a London postcode make boiler installs more expensive?
Generally yes — installer day rates tend to run higher in London than most of the UK, and tighter parking, congestion charging and building access in older blocks can add to labour time. That's on top of the usual property-size and fuel-type factors.
What's included in the £1.99 Boiler Quote Protection Check?
Seven sections built specifically around your boiler quote: the exact spec question to ask, a suitability check for your property, what should be included versus billed as extra, warranty guidance, Gas Safe/OFTEC certification checks, and payment protection guidance before you agree to anything.
