UK Solar and Heat Pump Deployment Data
Compare solar and retrofit heat-pump deployment, then look up domestic solar in your constituency. Grant applications, vouchers and completed installations are kept separate.
Deployment across Great Britain
Solar is reported monthly. Heat-pump and grant figures are quarterly and cover slightly different areas, so they are shown separately.

Installations per dwelling, England
Installations over the latest four complete quarters for every 1,000 dwellings — the comparison the counts above cannot support, because a region with more homes installs more heat pumps. England only: the dwelling stock this divides by is published for England.
| Area | Installations, 4 quarters | Per 1,000 dwellings |
|---|---|---|
| England | 39,208 | 1.5 |
| North East | 1,345 | 1.0 |
| North West | 4,368 | 1.3 |
| Yorkshire and the Humber | 3,501 | 1.4 |
| East Midlands | 4,037 | 1.8 |
| West Midlands | 3,105 | 1.2 |
| East of England | 5,980 | 2.1 |
| London | 2,006 | 0.5 |
| South East | 7,716 | 1.8 |
| South West | 7,150 | 2.6 |
Rates are installations per 1,000 dwellings, using MHCLG’s dwellings estimate for 2025, against figures for 2026. A dwelling is a self-contained unit of accommodation, occupied or not. It is not a household, and it is not the household projection this site stores elsewhere. Do not describe a rate built on this as "per household". Dwelling stock estimates are published for England only. Scotland and Wales publish their own series on their own definitions, so no Great Britain or United Kingdom dwelling total can be built from this source.

Paid heat-pump grants per dwelling, England
Paid Boiler Upgrade Scheme redemptions in the latest financial year for every 1,000 dwellings. A redemption is one installation at one property; it is not a household and not an application, and it is not every heat pump installed in the area.
| Area | Redemptions paid | Per 1,000 dwellings |
|---|---|---|
| England | 29,319 | 1.1 |
| North East | 980 | 0.8 |
| North West | 2,509 | 0.7 |
| Yorkshire and the Humber | 2,596 | 1.0 |

Capacity is not output
Installed capacity is what a system could produce in ideal conditions. Output is what it actually produces, and the ratio between them has a published name and a published number: the load factor.
UK solar ran at 11.1% in 2025, against 36.1% for offshore wind and 24.0% onshore (DUKES 6.3, United Kingdom). That is not a measure of how good solar panels are — it is mostly a statement about how often the sun is up. A panel that never failed and was never shaded would still not reach 100%.
The reason is unglamorous: it is dark half the time, often cloudy, and the sun is low for much of the year. A domestic array generates most of its annual total in a handful of summer months and very little in December and January — which is precisely when a household needs the most energy.
That mismatch is the central fact of domestic solar, and it is why battery storage and self-consumption matter so much more than they used to. Our solar panel calculator works through what a specific roof is likely to produce, and the weather and demand page explains why sunshine and demand run in opposite directions across the year.
Heat-pump grants
The Boiler Upgrade Scheme is the main route to a heat pump grant in England and Wales. Scotland runs its own schemes, which is one reason the figures here are shown by nation rather than as a single total.
An application is not an installation: only a redeemed voucher shows that work was completed. The grant may not cover other changes a home needs, such as larger radiators or better insulation.
Is either worth it for your home?
Solar works best on an unshaded roof when the household can use electricity during daylight. The solar calculator estimates output and payback for your roof.
Heat pumps need suitable insulation and enough radiator or underfloor area to heat the home at a lower flow temperature. Read the guides to air source heat pumps and air source versus ground source before requesting quotes.
Frequently asked questions
How many homes in the UK have solar panels?
DESNZ publishes installed solar capacity and the number of installations monthly, and breaks it down by parliamentary constituency. Note that capacity in megawatts and count of installations tell you different things: a single large ground-mounted farm can carry more capacity than thousands of rooftops.
How many heat pumps have been installed in the UK?
The figures here cover retrofit heat pumps — those fitted to existing homes, which is the harder and more relevant number. Heat pumps installed in new-build properties are counted separately in the construction statistics and are not included.
What is the Boiler Upgrade Scheme?
It is the England and Wales grant towards replacing a fossil-fuel boiler with a heat pump or biomass boiler. The figures on this page track applications, vouchers issued and redemptions — which are different stages, and a voucher issued is not yet an installation.
Do solar panels still pay for themselves without the Feed-in Tariff?
The Feed-in Tariff closed to new applicants in 2019 and was replaced by the Smart Export Guarantee, which pays less. The economics now rest mainly on the electricity you use yourself rather than what you export, so panels suit households that are home during the day or can shift usage into daylight hours.
Does a heat pump work in an ordinary British house?
Usually, but the house matters more than the weather. A heat pump delivers heat at a lower temperature than a gas boiler, so it needs enough radiator or underfloor surface to give that heat off, and it rewards insulation heavily. A well-specified install in a poorly insulated house is the common way for people to end up disappointed.
