Heat Pump for a New Build Home
New builds are the perfect environment for heat pumps. Designed with excellent insulation, airtightness, and often underfloor heating from the start, they need very little energy to stay warm. A heat pump in a new build can cost as little as £200-£400 per year to run — a fraction of heating bills in older properties. From 2025, the Future Homes Standard makes them the default.
This guide is for people buying or building a new home. For retrofit advice, see our pillar guide and installation guide.

Why New Builds and Heat Pumps Are a Perfect Match
| Factor | New Build | Older Home |
|---|---|---|
| Insulation | Excellent — built to latest standards | Varies — often needs improvement |
| Heat demand | Low — 4,000-8,000 kWh/year | Higher — 10,000-18,000 kWh/year |
| Heat distribution | Designed for heat pump (UFH, sized rads) | May need radiator upgrades |
| Airtightness | Excellent — minimal draughts | Varies — often draughty |
| System integration | Designed in from the start | Retrofit around existing infrastructure |
The Future Homes Standard
From 2025, the Future Homes Standard requires new homes to produce 75-80% fewer carbon emissions than previous building regulations allowed. In practice, this means heat pumps and high insulation levels are now the standard for new builds. See our gas boiler ban guide for the broader policy context.
Running Costs in a New Build
Annual Heat Demand
4,000-8,000 kWh
About half of older homes
Heat Pump Cost (Standard)
£325-£650/year
At 24.50p/kWh, COP 3.0
With Solar Panels
£100-£300/year
Free daytime electricity
New build running costs are remarkably low. Adding solar panels (many developers offer these as an option) reduces costs further. The combination is the gold standard for energy-efficient new homes.
What to Check When Buying a New Build with a Heat Pump
- System size: Confirm the heat pump is correctly sized for the property
- Hot water cylinder size: At least 170 litres, ideally 200+ for families
- Controls: Smart thermostat and weather compensation should be included
- Warranty: Check the manufacturer and installer warranties
- EPC rating: New builds with heat pumps should achieve A or B
- Solar option: Ask about solar panel packages

Frequently Asked Questions
Do all new builds have heat pumps?
From 2025, the Future Homes Standard effectively requires low-carbon heating. Most new developments include heat pumps as standard.
Are new build heat pumps different from retrofit?
Same technology, but installation is cheaper and more effective because the home is designed around the heat pump from the start.
Will a heat pump cost me extra?
For new builds, the heat pump cost is included in the purchase price. Running costs are very low due to excellent insulation.
Can I add solar panels?
Yes. Many developers offer solar as an option. The combination delivers the lowest possible running costs.
About this guide: This article is part of our comparison and decision hub. New builds represent the future of UK home heating — excellent insulation paired with heat pumps and solar panels. For retrofit properties, the BUS grant helps close the gap.
