How Much Does a New Boiler Cost in Manchester? (2026 Prices)
A straightforward like-for-like combi boiler swap usually costs around £1,800 to £3,500 fitted in 2026. That’s the most common job, where the new boiler goes in the same place as the old one. Converting from a system or regular boiler to a combi costs more, typically £3,000 to £5,700, because of the extra pipework and the removal of tanks and cylinders.
These figures come from published 2026 price guides by Checkatrade, Heatable and MyJobQuote. None of them give a separate figure for Manchester or the North West. All of them say labour costs are highest in London and lower in most other regions, so Greater Manchester prices generally sit within the national ranges rather than above them.
Average new boiler prices by job type
| Job | Typical installed cost | Source |
|---|---|---|
| Like-for-like combi swap | £1,800–£3,500 | Heatable (Sept 2026) |
| Premium combi swap (higher-end brand or model) | £3,000–£4,500 | Heatable |
| System boiler replacement | £1,800–£3,500 | Heatable |
| Regular (conventional) boiler replacement | £1,800–£3,000 | Heatable |
| Regular or system to combi conversion | £3,000–£5,700 | Heatable |
| Back boiler to combi conversion | £3,500–£6,000 | Heatable |
| Oil boiler replacement | £4,500–£5,500 | Heatable |
| Electric boiler installation | £1,700–£4,500 | Heatable |
Two more figures help with the comparison:
- Heatable says the median quote for a standard combi replacement, across 2,000 quotes from January to June 2026, was £2,300.
- MyJobQuote gives an average overall cost of £2,750. Checkatrade says a like-for-like combi swap costs £2,500 to £4,000, and a conversion to combi around £4,000.
The guides don’t agree exactly because they measure different things. Some are online quote averages, some include more extras as standard, and some are tradesperson estimates. Use them as a benchmark, not a fixed price.
What makes one quote higher than another
The boiler itself is usually the smaller part of the cost. Checkatrade gives an average of around £1,500 supply-only for a standard gas boiler. The rest is labour, parts and anything the job needs beyond a straight swap.
The biggest factors:
- Boiler type and output. A higher-output combi for a bigger home, or a premium model, costs more. MyJobQuote’s figures rise steadily from 24–27kW boilers up to 35–42kW.
- Swap or conversion. Changing from a regular or system boiler to a combi means taking out tanks and a cylinder and rerouting pipework. That typically adds a day or more of work.
- Moving the boiler. Moving the boiler to another room means new gas, water, condensate and flue routes. Checkatrade gives around £1,000 in extra labour for a relocation.
- Flue changes. Vertical flues through the roof, or anything that needs scaffolding, add cost.
- Gas pipe upgrades. Some older homes need a larger gas supply pipe to meet a modern combi’s demand.
- Brand and warranty length. Longer manufacturer warranties often come with more expensive models or approved installers.
What a fair quote should include
A proper fixed quote for a new boiler should normally cover:
- the boiler and flue kit
- labour by a Gas Safe registered engineer
- removal and disposal of the old boiler
- a system flush or clean, so sludge in the old system doesn’t damage the new boiler
- a magnetic system filter
- basic controls, such as a programmer or thermostat
- Building Regulations notification and registering the warranty with the manufacturer
- VAT
If any of these are missing, ask whether they’re included, and what it would cost to add them.
Common extras, if they’re not included:
| Extra | Typical cost (Checkatrade, 2026) |
|---|---|
| Magnetic filter | £60–£160 supply, plus £50–£150 to fit |
| Smart thermostat | Around £150 |
| Powerflush | Around £1,000 |
| Boiler relocation (labour) | Around £1,000 |
A powerflush isn’t always needed. A good installer will look at the condition of the system before recommending one. A chemical flush is often enough for a system in reasonable condition.
How long installation takes
According to Checkatrade:
- Like-for-like combi swap: about 4 to 6 hours, so usually done in a day
- Regular to combi conversion: 1.5 to 2 days
- System to combi conversion: up to 3 days
Expect to be without heating and hot water for at least part of the installation.
Is it worth repairing instead?
A new boiler usually makes sense when the old one needs an expensive repair and is already getting on in years, when parts are hard to get, or when it has broken down several times. For a single fault on a newer boiler, a repair is usually better value.
If you’re weighing up a repair, it’s worth comparing one-off boiler repair options first.
How to get an accurate price
Online averages will only get you so far. Two homes on the same street can need very different jobs. To get a firm price:
- Get a home survey or a photo-based quote that looks at the current boiler, flue position, pipework and gas supply.
- Ask for the quote to be itemised, including what’s included and what counts as an extra.
- Check the manufacturer warranty length and what you have to do to keep it valid. That’s usually an annual service.
- Make sure the installer is Gas Safe registered for the work, and check their card.
FAQs
Is there a grant for a new gas boiler?
Not generally. The Boiler Upgrade Scheme only covers heat pumps and some biomass boilers, not gas boilers. Some low-income households may qualify for help through energy supplier schemes. Check the current eligibility rules on gov.uk.
Can I spread the cost of a new boiler?
Many installers offer finance. Check the APR, the total amount payable and whether the installer is authorised by the FCA to arrange credit.
Do new boilers need servicing to keep the warranty?
Almost always. Most manufacturers require an annual service by a Gas Safe registered engineer, and a missed service can void the warranty.
Here’s what an annual boiler service involves and how long it takes.
