## How much does a heat pump cost in Wigan?

A fully installed air source heat pump in Wigan typically costs **£8,000–£15,000** before grants. That is in line with Ofgem's national BUS median of £12,908 (https://www.gov.uk/government/statistics/boiler-upgrade-scheme-statistics-august-2026) for April–June 2026. After the £7,500 grant, most Wigan homeowners pay £500–£7,500.

| Property type | Typical installed cost before grant | After £7,500 BUS grant |
| --- | --- | --- |
| 2-bed terrace or flat | £7,000–£10,000 | £0–£2,500 |
| 3-bed semi-detached | £9,000–£13,000 | £1,500–£5,500 |
| 4-bed detached | £11,000–£15,000 | £3,500–£7,500 |
| Oil-heated home (£9,000 BUS rate) | £11,000–£15,000 | £2,000–£6,000 |

With 45.6% of homes semi-detached, the 3-bed semi row is the most common Wigan install. A new hot water cylinder, radiator upgrades or electrical work are quoted separately after survey. Our heat pump installation page (https://alliantenergy.co.uk/services/heat-pumps) lists every extra.

## Are Wigan homes suitable for a heat pump?

Wigan is Greater Manchester's semi-detached borough: 45.6% of homes are semis, the highest share in the city region, and it has the fewest flats (7.4%). A typical 3-bed semi with a side or rear wall is the easiest property type to fit with an air source heat pump. Wigan also has the most oil-heated households in Greater Manchester (297), and those homes can claim the higher £9,000 Boiler Upgrade Scheme rate.

| Housing (Census 2021 / ONS EPC) | Wigan | Greater Manchester | England |
| --- | --- | --- | --- |
| Semi-detached | 45.6% | 37.9% | 31.5% |
| Terraced | 26.1% | 28.5% | 23.0% |
| Detached | 19.2% | 14.2% | 22.9% |
| Flats (purpose-built) | 7.4% | 16.3% | 17.1% |
| Heated by mains gas only | 83.9% | 78.1% | 74.0% |
| Owner-occupied | 66.4% | 58.0% | 61.3% |
| EPC band C or above | 53.6% | — | 53.3% |
| Median EPC score | 69 | — | 69 |

A good starting point

Wigan is above the England average for EPC band C (53.6% vs 53.3%), so more homes here can run a heat pump at low flow temperatures with few radiator changes. Older properties still need a room-by-room heat loss survey. See BUS eligibility for older homes (https://alliantenergy.co.uk/guides/old-property-boiler-upgrade-scheme-eligibility).

Most are. 83.9% of Wigan households heat with mains gas only, which is the profile most BUS heat pumps replace. 53.6% of homes are EPC band C or above (England: 53.3%), and homes below band C may need insulation or radiator upgrades first. A heat loss survey confirms this.

### How long does a heat pump installation take in Wigan?

Typically 2–3 days on site. The Boiler Upgrade Scheme voucher must be approved first, which usually takes 2–4 weeks, and we handle the application. Most customers go from survey to switch-on in 6–10 weeks.
