• Like-for-like combi boiler replacement — £1,699 to £2,499. The most common job in Manchester. Your old combi comes out, your new combi goes in the same position on the same wall. No structural changes, no cylinder work.
• Like-for-like system boiler replacement — £1,899 to £2,799. Replaces an existing system boiler without changing the hot water cylinder. Cylinder remains in place.
• Like-for-like conventional (heat-only) boiler replacement — £1,899 to £2,799. Old conventional boiler out, new one in. Cylinder and cold water tank remain.
• Conventional or system boiler to combi conversion — £2,199 to £3,500. The cylinder in the airing cupboard and cold water tank in the loft are removed. New pipework is run. The freed-up space is yours — but the job is more complex and takes 1–2 days.
• Back boiler to combi conversion — £2,500 to £4,000. The back boiler and fire surround are removed. The chimney breast recess is boarded and plastered. The new combi is wall-mounted. A full day to two-day job depending on property.
• New boiler installation (new build, extension or first-time central heating) — from £2,499. Full pipework, radiators and system creation priced individually — call for a bespoke quote.

What Makes a Manchester Boiler Installation Cost More

The headline price applies to a straightforward like-for-like replacement. Here are the specific factors that increase cost — and by roughly how much:

• Boiler relocation — moving the boiler to a different wall or room requires new gas pipework and a new flue route. Additional cost: typically £200–£500 depending on distance and complexity.
• New flue position — if the existing flue position cannot be reused (e.g. new boiler requires a different flue diameter or angle), a new flue penetration through the wall is needed. Additional cost: £100–£250.
• 22mm to 28mm gas supply upgrade — older Manchester properties, particularly Victorian terraces in Salford, Hulme and inner Manchester, sometimes have undersized gas supply pipes. Upgrading from 15mm or 22mm to 28mm ensures adequate gas pressure for a modern boiler. Additional cost: £150–£400 depending on run length.
• Full powerflush — if your system has significant sludge or scale build-up, a powerflush using specialist equipment may be recommended. A chemical flush (included in all our quotes) handles routine contamination. A full powerflush is a separate service. Cost: £400–£700 for a typical Manchester home.
• Cylinder disposal (on conversions) — included in our conversion prices above. No additional charge.

ECO4 Grants and Free Boiler Schemes in Greater Manchester

If you are on qualifying benefits, you may be entitled to a free boiler replacement through the government's ECO4 (Energy Company Obligation) scheme. Here is what you need to know for Manchester:

• Who qualifies: Households receiving Universal Credit, Pension Credit, Child Tax Credit, Working Tax Credit, Housing Benefit, or Income Support. The property must also have a low energy efficiency rating (EPC D, E, F or G).
• What is covered: A replacement boiler at no cost to you, installed by a registered ECO4 installer.
• Greater Manchester context: Greater Manchester Combined Authority has actively promoted ECO4 uptake. Many older properties in Salford, Rochdale, Oldham and Wigan are eligible.
• How to check: Call 07305 687 331 and we will carry out a free eligibility check. We work with ECO4 funding bodies and can refer you to the right scheme if you qualify.

If you do not qualify for ECO4, our 0% finance option allows you to spread the cost from just £29/month over 12–120 months — no deposit required, no interest charges.

Manchester vs National: Are Local Installers Cheaper?

A common question is whether a national online platform like BOXT or Heatable is cheaper than a local Manchester company. The honest answer in 2026:

• On price: We are comparable — within £50–£100 on most boiler models. Nationals benefit from buying power; we benefit from lower overhead (no call centres, no national advertising budget).
• On warranty: We are Worcester Bosch accredited installers. BOXT and Heatable are not always accredited for every brand they install. Accredited installation is the only route to the full 10 year Worcester Bosch warranty — this has a real financial value.
• On hidden extras: National platforms sometimes offer a low headline price then charge for the thermostat, filter or flush separately. Our prices include everything from the start.
• On labour quality: National platforms subcontract. We use our own Gas Safe team. If something is not right, you call us directly and we come back — not a call centre that tries to find an available subcontractor.
