Landlord EPC upgrades: tax relief turns on what the work replaces

ended 30. September 2026

Landlords in England and Wales are being urged to start early on bringing rented homes up to EPC C by 1 October 2030. The government has confirmed the standard and a £10,000 cost cap per property, with spending on relevant work since 1 October 2025 counting towards it, but has not yet made the regulations. On 28 September the NRLA and the Energy Saving Trust warned that waiting risks what NRLA chief executive Ben Beadle called “a scramble for installers, finance and advice that drives up costs”.

The tax relief on that work is far less even. On the government's own examples, a heat pump replacing an existing heating system is an allowable expense against rent, but a heat pump fitted as a home's first heating system is capital, and so is first-time loft insulation. Capital spend gets no relief against rental income and may only reduce a capital gain when the property is sold, which could be decades away. Same cap, same deadline, and relief by accident of history.

The VAT clock runs out first. Installing energy-saving materials in homes is zero-rated until 31 March 2027 and 5 per cent from 1 April 2027, three and a half years before the deadline.

  1. Is “start early” the right advice when the tax relief on the work is this uneven, or should the rules change before 2030?
  2. Which landlords end up funding an upgrade with no relief against rent, and how will they pay for it: savings, a further advance or a sale?
  3. Do you have a landlord client whose plans to retrofit, refinance or sell this would change? If so, please give as much colour and detail as possible.

Landlords face a genuine timing problem. Leaving upgrades until close to 2030 risks higher demand for installers and less time to arrange the funding, but spending early without understanding the full cost can be expensive too. The uneven tax treatment makes that planning harder because similar EPC improvements can have very different net costs depending on what the work replaces.

From a mortgage perspective, if the work needs to be funded through a further advance or remortgage, the cost isn't just the building work but the interest on that borrowing. Plan early enough to know whether the property still stacks up financially after the upgrade.

This is really all about timing. As usual, the Government have over-complicated the whole thing and the goal-posts keep changing with the metrics (MEES) for the EPC ratings. The new rules will come in from 1st October 2029 therefore landlords should look to get an EPC of C under the current metrics as close as possible prior to this date to enable them to have 'Grandfather Rights' which will essentially extend the current EPC for another 10yrs under current terms. They should be mindful that assessors and installers will be busy so any small wins should be carried out before this as it will be like open season once the new regulations come in. As usual, it is unlikely that assessors will be plentiful so landlords should be informed and organised.

This goes well beyond the right hand not knowing what the left is doing. It's dysfunctional governance. Landlords are urged to "start early" on the 2030 EPC C target, yet HMRC tax law contradicts. Spend £10,000 on energy improvements and the tax treatment is wildly unequal: replacing an existing system is an allowable revenue expense against rent, but first-time additions (loft insulation, a heat pump) are capital spend with zero immediate income tax relief. Wait and you risk installer bottlenecks and rising costs; act now and you lock in 0% VAT on materials before it reverts to 5% on 31 March 2027. Older stock, solid-wall terraces, off-grid cottages and high-rate taxpayers bear the brunt. Many will rationalise, selling lower-yielding units to owner-occupiers before 2030 rather than funding upgrades from taxed income. Plenty have given up on the UK altogether: portfolios liquidated, rebuilding overseas.

“Start early” is sensible, but it should not mean “spend blindly”.

Landlords are being told to invest up to £10,000 per property, yet the tax treatment can depend on whether the work replaces something already there or creates something new. Two landlords making virtually the same EPC improvement can therefore get very different tax outcomes.

That matters when portfolios are leveraged. Some landlords will fund upgrades from cashflow, others through further borrowing, and some will decide the numbers no longer justify keeping the property.

The VAT timing makes early planning even more important because qualifying energy-saving installations are zero-rated only until 31 March 2027, then revert to 5%.

The danger is a 2030 rush where landlords face higher labour costs, worse availability and rushed financing decisions.

Start early, yes. But first model the tax, finance and exit properly.

“Start early” makes sense for planning, but landlords need a funding plan alongside the works schedule. A tax deduction is not cash upfront, and relief that may only arise on a future sale does nothing to pay today’s installer.

Through Bridging Loan Directory’s reporting, we see how refurbishment funding depends on available equity and a realistic route to repayment. An EPC upgrade should not simply be assumed to produce a matching increase in property value or borrowing capacity.

The practical question is what the landlord must fund after grants and tax treatment are established, whether existing borrowing allows further finance, and how any additional debt will be repaid.

Clearer tax treatment would help landlords budget. But waiting for a possible tax change is not a funding strategy, and borrowing costs could outweigh a saving from bringing work forward.

“A landlord can have equity in a property and still be unable to borrow for an EPC upgrade if the rent doesn’t pass the lender’s affordability test.”

For portfolio landlords, the costs could add up across several properties. A further advance or remortgage may help fund the work, but the amount available will depend on the property, the rental income and the lender’s criteria. An improved EPC rating should not be assumed to increase the property’s value or borrowing capacity by the same amount as the work costs.

My advice is to review each property early: establish what work is needed, ask an accountant about the tax treatment, and check the funding options before committing to a programme of upgrades. That gives landlords time to decide whether each property still makes financial sense ahead of the 2030 deadline.
