Most new builds are not eligible for the Boiler Upgrade Scheme in England and Wales. Some self-builds can be, depending on the circumstances, so check eligibility before relying on a grant in your budget. In Scotland, ask Home Energy Scotland about new homes; Northern Ireland has no dedicated homeowner heat pump grant at present.
Plots in Cumbria with tight boundaries benefit from fixing the outdoor unit position before landscaping is finalised. Small developments near Cumbria can be designed plot by plot, with heat loss worked out from each house type's drawings. Builders working across Cumbria can coordinate first and second fix with an installer covering Cumbria.
Who it suits
- Small builders and developers working on one-off homes or small groups
- Self-builders planning heating alongside the structure
- Replacement dwellings and major conversions treated as new homes
- Homes designed with underfloor heating on one or more floors
Grants and rules for heat pumps in England
Homes in Cumbria can use the Boiler Upgrade Scheme, which takes £7,500 off the cost of an air source heat pump when it replaces fossil-fuel or electric heating. Replacing oil or LPG heating qualifies for £9,000 for installations from 21 July 2026 to 31 March 2027, and air-to-air systems for £2,500. The MCS-certified installer named in your quote applies for the grant and deducts it from the price.
There is no VAT on installing a heat pump anywhere in the UK until 31 March 2027. In England most houses can have an air source heat pump under permitted development, provided the unit meets the MCS noise and siting standards; the old 1 m boundary limit was removed on 29 May 2025. We flag listed buildings, flats and sensitive conservation-area positions at survey.
New-build and self-build heat pumps prices in Cumbria
Here are typical prices for new-build and self-build heat pumps in Cumbria, installed and including VAT. Use the guide price tool for a figure based on your home, then a survey confirms it in writing.
| Home | Typical size | Installed guide price |
|---|---|---|
| 1–2 bedroom flat or small terrace | 4–5 kW | £9,500–£12,500 |
| 2–3 bedroom terrace or semi | 5–7 kW | £10,500–£13,500 |

| 5+ bedroom or larger older house | 11–16 kW | £16,500–£22,500 |
Installed, inc VAT: unit, cylinder, controls, minor pipework and commissioning. Most new builds are not eligible for grant funding, so no deduction is shown.

New-build and self-build heat pumps questions
Is underfloor heating worth it in a new build?
For many new homes, yes, because underfloor heating runs at low water temperatures that suit a heat pump, and laying pipes during the build is far easier than adding them later. It also frees up wall space. Radiators cost less and respond faster, so some self-builders combine underfloor heating downstairs with radiators upstairs. The design shows the flow temperature each option needs.
How long does a new-build heat pump installation take?
It is split across the build. First fix typically takes a few days once the structure is up, and second fix with commissioning takes a few more days near completion. Underfloor heating in screed then follows a gradual drying-out schedule. Exact timing depends on your build programme, which we agree with your builder so trades are not left waiting on each other.
Where should the outdoor unit go on a new build?
Somewhere with free airflow, a solid base and drainage, away from bedroom windows and boundaries where possible, and positioned to pass the MCS noise assessment. On a new build this can be planned into the landscaping, such as a side return or screened area near the plant room, which keeps pipe runs short. Planning rules differ by nation, so we check the position at design stage.
Do new builds have to have a heat pump?
The rules depend on the nation and when your project was approved, so check with your architect or building control. New homes in England are being built to tighter carbon standards, and Wales, Scotland and Northern Ireland set their own building regulations. A heat pump is one of the main ways new homes meet these standards, and we design the heating to whichever applies.
