UK solar VAT is about to start appearing on household bills. Homeowners in the United Kingdom currently pay no value-added tax on residential solar panels or battery storage. pv magazine reported that this zero rate ends on 1 April 2027, when a 5% charge takes effect. The change arrives with Warm Home Loans, a government-backed lending programme for solar, batteries and heat pumps. It also comes alongside cuts to clean-heat budgets. The Boiler Upgrade Scheme survived, but its forward budget shrinks by around £700 million ($932 million). For anyone weighing an installation, about five months of tax-free buying remain. The financing rules now published shape what happens after that.
Critically, it will ensure that households across society can overcome any financial barriers, making sure that the benefits are felt where they are most needed.

Key takeaways
- VAT deadline: A 5% VAT charge applies to UK residential solar panels and battery storage from 1 April 2027, ending the current zero-tax treatment.
- New loans: Warm Home Loans use government backing for part of the lending risk, with Tandem Bank, Sunsave Energy, Hometree Finance and HomeServe Finance listed as participants.
- Grant cut: The Boiler Upgrade Scheme gets £400 million ($536 million) for 2027-28, down from a previously planned £600 million ($804 million).
- Defence trade-off: £1 billion ($1.3 billion) is being taken from the Warm Homes Plan's multi-year budget to fund defence, against a £335 million ($449 million) top-up in 2027.
- Social housing: A further £100 million ($134 million), still awaiting final approval, could fund up to 57,000 solar installations for social housing tenants.

What Changes on 1 April 2027 for Solar and Battery Buyers
A UK household installing rooftop panels or a home battery today sees no VAT on its invoice. From 1 April 2027, the same purchases carry a 5% value-added tax. Value-added tax is a consumption tax added to the price of most goods and services.
The government released the tax change at the same moment as guidance for its new loan programme, so the two land together. One nudges the price of equipment up. The other is designed to make paying for that equipment cheaper.
Five per cent is a modest rate, but it is a fixed cost with a known start date. The published details do not say whether the contract date or the installation date decides which side of the line a purchase falls on. Buyers close to the cutoff have every reason to ask their installer before committing.
How Warm Home Loans Are Meant to Lower Financing Costs
The core of Warm Home Loans is the government absorbing part of the lending risk. That backing lets lenders finance solar panels, batteries and heat pumps on better terms. Applicants can come through an installer, a retailer or a mortgage provider, or approach a participating lender directly.
The UK government names Tandem Bank, Sunsave Energy, Hometree Finance and HomeServe Finance among the participants. Its guidance also permits stacking. A household can pair a Warm Home Loan with a grant or other support to push its total financing cost lower.
Chris Hewett, chief executive of the trade body Solar Energy UK, said the scheme would let more homes install solar in the coming year than in any year before. He also said it would help households across society clear financial barriers. That is a forecast from the industry's own lobby group, and no uptake figures exist yet to test it.
Where the Heat Pump Grant Budget Was Cut
The Boiler Upgrade Scheme is the grant that helps households replace fossil boilers with heat pumps. It stayed open despite predictions that it would be scrapped. Its future funding did not escape, and the forward budget falls by around £700 million ($932 million).
For 2027-28 the government has committed £400 million ($536 million), with later years expected to rise roughly in line with inflation. The earlier plan had set £600 million ($804 million) for 2027-28, £683 million ($915 million) for 2028-29 and £709 million ($950 million) for 2029-30. The first year alone is about a third below what was previously planned.
Demand has been heavily concentrated. The UK government says the scheme received 151,136 voucher applications from May 2022 through August 2026, and 98% of them were for air-to-water heat pumps. That pace is far short of the official goal of 450,000 heat pump installations a year by 2030. A smaller grant pot does nothing to narrow that gap.
Defence, Social Housing and the End of Gas Standing Charges
The broader Warm Homes Plan gets an extra £335 million ($449 million) in 2027. Over the same period, £1 billion ($1.3 billion) is being pulled from its multi-year budget to help pay for defence. The top-up is much smaller than the withdrawal.
Social housing tenants could gain from a further £100 million ($134 million), though the money still needs final approval. If confirmed, it would pay for as many as 57,000 solar installations in the financial year the announcement covers. At that maximum, the money works out to roughly £1,750 per installation.
In a separate pledge, the government plans to scrap fixed standing charges on gas bills and move those costs into the price per unit used. It estimates a saving of around £45 ($60) a year for 60% of households. Homes that burn less gas, including those that have switched to heat pumps, are the ones this shift favours.
| Financial year | Previous allocation | Current commitment |
|---|---|---|
| 2027-28 | £600 million ($804 million) | £400 million ($536 million) |
| 2028-29 | £683 million ($915 million) | Expected to rise roughly with inflation |
| 2029-30 | £709 million ($950 million) | Expected to rise roughly with inflation |
What supports and what undermines UK home clean energy uptake
The case for
- Government backing for part of the lending risk should let Warm Home Loans lenders offer cheaper finance than unsupported loans.
- Guidance allows grants and other support to be combined with a Warm Home Loan, lowering total financing costs further.
- A possible £100 million for social housing could reach up to 57,000 installations for tenants who rarely buy solar themselves.
- Folding gas standing charges into unit prices rewards low-gas homes, including heat pump users.
The case against
- The 5% VAT from 1 April 2027 adds a fixed cost to every residential solar and battery purchase.
- The Boiler Upgrade Scheme's 2027-28 budget drops from £600 million to £400 million.
- £1 billion leaves the Warm Homes Plan for defence, far outweighing the £335 million added in 2027.
- Heat pump uptake, at 151,136 voucher applications over more than four years, is far from the 450,000-a-year target for 2030.
What to be careful about
- Households that miss the 1 April 2027 deadline pay 5% more on solar and battery equipment.
- The £100 million for social housing solar is not yet approved and could shrink or fail to materialise.
- Lower Boiler Upgrade Scheme budgets could mean grant money runs out sooner within each year.
The bottom line
Britain's home energy policy now pulls two ways at once. The 5% VAT from 1 April 2027 puts a fixed cost on every residential solar and battery purchase, while Warm Home Loans and grant stacking aim to cut the cost of paying for one. Clean heating takes the heavier blow: a Boiler Upgrade Scheme budget around £700 million lighter, and £1 billion moved from the Warm Homes Plan to defence. Hewett's expectation of a strong year for household solar rests on lenders offering terms that outweigh the new tax. The VAT date is fixed. The social housing money, and whether the loans deliver, still have to prove themselves.
What to watch
- On 1 April 2027 the 5% VAT on residential solar panels and battery storage takes effect, ending tax-free purchases.
- Watch for final approval of the £100 million for social housing solar, which would fund up to 57,000 installations; no date has been set.
- Watch for the start of the reduced £400 million Boiler Upgrade Scheme allocation for the 2027-28 financial year, and whether grant demand outruns it.
