New homes in England are being built to tighter carbon standards, and Wales, Scotland and Northern Ireland each set their own building regulations; a heat pump is one of the main ways new homes meet them. We work from your architect's drawings and energy assessment, then fit in with the build programme: first-fix pipework before floors and walls are finished, and the outdoor unit, cylinder and controls once the building is weathertight.
For barn conversions and replacement dwellings near Surrey, the design starts from the specification of the new walls, floors and glazing. Builders working across Surrey can coordinate first and second fix with an installer covering Surrey. Small developments near Surrey can be designed plot by plot, with heat loss worked out from each house type's drawings.
Who it suits
- Architects and builders who want a heat loss design from the drawings
- Self-builders planning heating alongside the structure
- Small builders and developers working on one-off homes or small groups
- Homes designed with underfloor heating on one or more floors
Grants and rules for heat pumps in England
In England the Boiler Upgrade Scheme gives £7,500 towards an air source heat pump (£9,000 if it replaces oil or LPG, from 21 July 2026 to 31 March 2027), and since 28 April 2026 a valid EPC is no longer needed. The grant is applied for by the MCS-certified installer and shown as a deduction on your quote.
Installing heat pumps is zero-rated for VAT across the UK until 31 March 2027. Since 29 May 2025, permitted development in England allows up to two air source heat pumps on a house, each up to 1.5 m³, with no blanket 1 m boundary rule — the installation must still meet the MCS planning standards, including the noise check. Listed buildings, flats and some conservation-area positions need extra consent, which we check at survey.
New-build and self-build heat pumps prices in Surrey
These are guide prices for Surrey, installed and including VAT. Your final price is fixed in a written quote after the survey and depends on the heat loss of the house, the radiators that need changing and where the unit goes.
| Home | Typical size | Installed guide price |
|---|---|---|
| 1–2 bedroom flat or small terrace | 4–5 kW | £10,150–£13,400 |
| 2–3 bedroom terrace or semi | 5–7 kW | £11,250–£14,450 |
| 3 bedroom semi or small detached | 6–9 kW | £12,850–£16,600 |
| 4 bedroom detached | 8–12 kW | £15,000–£19,250 |
| 5+ bedroom or larger older house | 11–16 kW | £17,650–£24,100 |
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
Can a self-build get the Boiler Upgrade Scheme grant?
In some cases. In England and Wales the scheme is aimed at existing homes and most new builds are not eligible, but some self-builds can qualify depending on circumstances, so check eligibility before including a grant in your budget. If the scheme can apply, the MCS-certified installer named in your quote handles the application. Scotland and Northern Ireland are outside the scheme.
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.
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.
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.
