EPC Upgrade Finance for Commercial Property in England

If you own let commercial property in England, you can fund EPC improvements in three main ways: add a capital expenditure line to an existing commercial mortgage, use short-term bridging finance while works are carried out, or use a specialist development-style facility where tenants must vacate. Which suits you depends on the size of the works, how long the building will be out of income, and what the property is worth once the rating improves. The rules are shifting, so it pays to plan funding before a deadline forces your hand.

TL;DR

• Let commercial buildings in England and Wales currently need at least an EPC E, unless a valid exemption is registered.
• The government has said the proposed 2027 interim EPC C milestone will not go ahead. It proposes EPC B from 2031 for larger private rented buildings, where cost-effective.
• Funding ranges from a further advance or capex line, through bridging finance, to development finance for heavy refurbishment.
• Lenders want a costed retrofit plan, evidence of the effect on value and rent, and a borrower who can contribute to the cost.
• Grants are narrow for commercial landlords, so most upgrades are paid for with debt structured around the property.

What the rules require today, and what is coming

The Minimum Energy Efficiency Standards (MEES) regime uses the EPC rating as its test. In England and Wales, a landlord generally cannot let or keep letting a commercial property rated F or G unless it is improved to at least E or a valid exemption is registered. That is the floor you are working to now.

The direction of travel has been clearer than the detail. Earlier proposals pointed to EPC C by 2027 and B by 2030. The government’s interim response to the MEES consultation, updated 18 June 2026, says the 2027 interim EPC C milestone will not be taken forward. It proposes EPC B from 2031 for private rented buildings over 1,000 square metres in England and Wales where cost-effective, and says buildings under 1,000 square metres should stay subject to EPC E.

Many guides still quote the older 2027 and 2030 dates. Treat those as superseded, and check the government page for the latest position before you commit to a programme.

Two practical points sit alongside the minimum rating:

• Display duty. A non-domestic property that must have an EPC has to display it if the floor area is over 500 square metres, the public frequently visits and an EPC has already been produced, as set out on GOV.UK’s guidance for business premises.
• Exemptions. Landlords may register an exemption where the expected value of bill savings over 7 years is less than the cost of buying and installing the recommended improvements, per the landlord guidance updated 5 May 2026.

An exemption can be the right answer for a poor building where the sums do not work. But a property that cannot be legally let without one will be harder to sell, refinance or value well. Lenders will see that.

Why EPC works are a finance question, not just a compliance one

For a portfolio landlord, a rating below the line is a risk to rental income, to valuation and to the loan-to-value (LTV) headroom a lender has assumed. Funding the fix is therefore part of how you protect the asset.

The scale varies enormously. Upgrading lighting and controls in a small unit is a modest outlay. Replacing a heating system, improving the building fabric and adding glazing across a multi-let office is a very different project. The law firm Pinsent Masons describes the financing need as ranging from an ancillary capital expenditure line for limited works to development-type finance where substantial works require tenants to vacate. In the latter case, lenders assess whether the property can be re-let quickly and on favourable terms.

That range is the most useful way to think about your options. Match the product to the works, not the other way round.

Funding routes compared

The last row draws on a BTG Eddisons overview of decarbonisation funding, which lists green mortgages and sustainability-linked loans, energy performance contracts, power purchase agreements, lease finance and blended funding. Under an energy performance contract, a contractor installs and finances the measures and the owner repays from reduced energy bills over an agreed term. That works best where the occupier or owner pays the energy bills and the savings are measurable, which is less common in multi-let buildings where tenants pay their own.

Commercial mortgages and refinancing

If your existing debt is due for renewal, folding EPC works into a refinance can be efficient. You negotiate once, and the lender prices the whole picture. We arrange this through our commercial mortgage service, working with lenders beyond the high street who will consider mixed-use, multi-let and non-standard stock.

The catch is valuation. A valuer will usually assess the property as it stands, so the uplift from a better rating may not be recognised until the works are done. That is where a staged approach helps: fund the works first, then refinance onto longer-term debt on the improved asset.

Bridging finance for the works period

Bridging is useful when speed matters, such as a lease event, a sale on the horizon, or a rating that needs to be fixed before a letting. It is short-term and costs more than a term loan, so it only makes sense with a clear exit, typically a refinance onto a commercial mortgage or a sale. Our bridging finance page explains how these loans are structured.

A realistic plan answers three questions: how long will the works take, what will the building be valued at on completion, and which lender will take the refinance? If any of these is vague, the exit is weak.

Development finance for heavy refurbishment

Where works need vacant possession, such as a full plant replacement or a major fabric upgrade, lenders treat the project like a refurbishment. Drawdowns are staged against progress, and the lender cares about the re-letting plan. Our development finance team also arranges mezzanine debt and joint venture equity where the senior loan does not cover the full cost. If you are weighing refurbishment against conversion, our piece on conversion finance versus new build covers how lenders view each.

What lenders look at

Lenders do not fund a rating. They fund a property and a borrower. According to Pinsent Masons, they are likely to consider the extent and cost of the works, the effect on cash flows and valuations, the letting impact, and the sponsor’s covenant and ability to fund some or all of the works.

In practice that means preparing:

1. A costed retrofit plan. Itemised works, contractor quotes, programme and contingency.
2. The current EPC and recommendation report. This shows which measures the assessor expects to move the rating.
3. Payback and valuation evidence. Energy savings, rental impact and a view on value after works.
4. Tenancy information. Lease expiries, break dates, who pays for what, and whether tenants need to move out.
5. Your own contribution and track record. Equity in the project and a history of delivery.

Pinsent Masons also notes that lenders favour properly costed plans showing costs, payback periods and valuation effects, and that early engagement can support funding discussions, including sustainability-linked loans with KPIs. Speaking to a broker before you appoint contractors lets us shape the plan to what lenders want to see.

The Carbon Trust’s guide to financing energy efficiency projects gives a useful checklist for the business case: capital, implementation and operating costs, direct financial benefits, additional benefits, technical, cost and market risks, financing options and incentives, all backed by reliable data. It also observes that efficiency projects can be seen as non-essential, technically complex and relatively small, so a clear appraisal is needed to win over decision-makers.

Grants and tax relief: what is realistic

Anyone hoping grants will cover a commercial landlord’s upgrade should temper expectations. Most schemes are targeted, regional or limited to certain organisations.

• Energy Resilience Fund (England). A blended package of 60% loan and 40% grant, between £25,000 and £250,000, for registered charities and community interest companies, as described by Bath and North East Somerset Council. Most commercial landlords will not qualify.
• Boiler Upgrade Scheme. Grants of up to £7,500 towards replacing fossil fuel heating with low-carbon alternatives, summarised by the FSB. Check eligibility for your building type on the official scheme page before relying on it.
• Full expensing. Businesses can deduct 100% of the cost of qualifying plant and machinery, including solar panels and energy-efficient equipment, from profits in the year of purchase, per the same FSB guide. Take advice from your accountant on whether your structure benefits.

Schemes elsewhere in the UK, such as the Development Bank of Wales Green Business Loan Fund for Welsh businesses and Business Energy Scotland’s SME loan for Scottish ones, do not apply to buildings in England. They are worth knowing as benchmarks: the Welsh scheme offers loans of £1,000 to £1,500,000 with an interest rate discount of 3.5% to 5% and no arrangement fee, and expects security such as a debenture, legal charge and personal guarantees. That is a sign of the security packages lenders generally expect for this kind of lending.

Looking further ahead, the government’s heat and buildings factsheet notes that the Green Finance Institute has identified property linked finance as a possible long-term, non-recourse solution that stays with the property, though it may need primary legislation. It is not available now, so do not plan around it.

Prioritising across a portfolio

If you hold several buildings, treat EPC as a programme rather than a series of emergencies.

1. Audit every EPC. Record the rating, expiry date and recommendations for each property.
2. Sort by risk. Buildings at F or G need action first. Large buildings over 1,000 square metres are the ones the proposed EPC B standard would reach.
3. Sort by return. Prioritise measures with the best rating gain per pound, and buildings where a lease event gives you access.
4. Check the exemption test. Where the 7-year savings test says works are not cost-effective, the exemption route may be the honest answer.
5. Plan the debt. Group works by timing so one facility, perhaps a revolving credit facility against the portfolio, can fund them rather than negotiating property by property.

Our case study of a £600k revolving credit facility secured against a £5m property portfolio shows how a flexible line can release capital across multiple assets without selling any of them.

Our perspective

The mistake we see most often is treating EPC works as a compliance cost to be dealt with at the last minute. Last-minute funding is expensive funding. Owners who approach lenders with a costed plan and a clear exit get better terms than those who arrive with a deadline and a quote on the back of an envelope.

We also think the regulatory uncertainty is a reason to act on the sensible works now, not to wait. The 2027 milestone has gone, but a 2031 EPC B proposal for larger buildings is still on the table, and the buildings most exposed are those that are already hard to let. Tenants and buyers are asking about energy performance regardless of what the statute says.

Our role is to match the work to the right money. A modest fit-out may only need a capex line from your existing lender. A deeper refurbishment may need bridging, then a term loan, perhaps with mezzanine to close a gap. We have access to specialist lenders and private credit funds beyond mainstream banks, which matters when a building is unusual or the timetable is tight.

FAQ

Do I need an EPC B on my commercial property now?

No. The current requirement for let commercial property in England and Wales is a minimum of E, unless you have a valid exemption. The government proposes EPC B from 2031 for private rented buildings over 1,000 square metres where cost-effective. Check the government’s MEES page for the latest position.

Can I use a bridging loan to pay for EPC improvements?

Yes, where the works are short and there is a clear exit, such as a refinance onto a commercial mortgage or a sale. Bridging costs more than term debt, so it suits a defined project rather than long-term funding. The lender will want a costed plan and a realistic timetable.

Will a lender value my property higher after EPC works?

Possibly, but not automatically. Lenders consider the effect of works on cash flow, valuation and letting prospects. A costed plan with payback and valuation evidence puts you in a stronger position to make the case.

Are there grants for commercial landlords in England?

Few. The Energy Resilience Fund is aimed at registered charities and community interest companies, and the Boiler Upgrade Scheme covers heating replacement only. Tax relief such as full expensing may help depending on your structure, so speak to your accountant.

When can I register an EPC exemption?

Government guidance allows an exemption where the expected value of energy bill savings over 7 years is less than the cost of buying and installing the recommended improvements. Read the full landlord guidance before registering one.
