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.
New homes in Northumberland designed with underfloor heating downstairs get a low flow temperature that suits a heat pump. Self-builders in and around Northumberland can bring us in at drawing stage so the heat pump, cylinder and pipe routes are designed in from the start. Small developments near Northumberland 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
- Replacement dwellings and major conversions treated as new homes
- 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 Northumberland
Here are typical prices for new-build and self-build heat pumps in Northumberland, 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 |

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.
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.
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.
When do you need to be involved in a new build?
Ideally before the drawings are finalised, so the plant space, outdoor unit position and emitters are agreed with your architect. At the latest, the design should be done before first fix, when pipework goes in under floors and inside walls. Late involvement usually means compromises, such as a cylinder in an awkward space or pipe runs boxed in afterwards.
