Sustainability business loans: Can accountants use them to improve EPC and meet MEES?

Short answer: Yes — in many cases an accountant or accountancy firm can use a sustainability business loan to fund building works that improve a commercial EPC and help meet Minimum Energy Efficiency Standards (MEES). Success depends on the nature of the works, the lender’s product rules and the evidence you supply (existing EPC, contractor quotes, ownership/consent).

Quick answer — can a sustainability business loan improve EPC and meet MEES?

Short: Often yes. A sustainability or retrofit business loan can fund many energy-efficiency and low-carbon measures that raise an EPC rating and assist you in meeting MEES obligations — provided:

• The proposed works are eligible under the lender’s product rules (e.g., fabric improvements, heating, renewables, controls).
• You can demonstrate the baseline EPC and the likely uplift (estimate from an assessor or contractor).
• The legal/lease position is clear (you own the building or have landlord consent for tenant-led works).
• Your business meets the lender’s borrowing criteria (turnover, profitability, security where required).

Typical eligible works include insulation, glazing, LED lighting, efficient HVAC, heat pumps, solar PV and battery storage. Lenders normally require contractor quotes, a project plan and an EPC to assess the likely uplift. If you’re ready, start a Free Eligibility Check: Get Started — Free Eligibility Check.

What MEES and EPC actually require (for accountants/landlords)

Quick MEES refresher

MEES (Minimum Energy Efficiency Standards) set minimum EPC ratings for commercial properties that are let. The legal minimum and enforcement timeline can change — check gov.uk for the latest. Currently, commercial properties must meet the minimum standard set by government (historically an E rating or better for many measures), or reasonable steps must be taken to achieve it before letting or continued letting.

Who MEES applies to

MEES generally applies to landlords of commercial property. However, accountants who occupy premises (owner-occupied) or who manage property for clients may be affected by MEES through lease terms and future onward sale value. Tenants proposing to bring a property into compliance need landlord consent for some works.

Common exemptions

There are exemptions and allowances — for example, if works are not technically feasible or cost-effective, or where third-party consent (landlord) cannot be obtained. Always verify whether an exemption applies via gov.uk guidance or specialist legal advice.

Official gov.uk guidance: see MEES guidance on gov.uk.

Which retrofit or sustainability works are usually eligible for finance?

Lenders and specialist retrofit funds typically look for measures that demonstrably reduce energy demand or decarbonise heating. Commonly financed works include:

• Insulation and building fabric upgrades (walls, roof, floors).
• Double/triple glazing or improved windows.
• LED lighting and lighting controls.
• Efficient boilers and heat-pump installation.
• HVAC upgrades and building management systems (BMS) / controls.
• Solar PV, battery storage and associated electrical upgrades.
• EV charging infrastructure for staff or visitors.
• Energy performance monitoring and retrofit project management.

Ineligible or low-priority items are usually cosmetic works or non-energy upgrades unless they form part of a wider, qualifying retrofit package.

Lenders typically want:

• At least two contractor quotes and a scope of works.
• A baseline EPC and an estimated post-works EPC uplift.
• A project timetable and cost breakdown.

Types of sustainability finance available to accountants

Different finance products suit different projects and balance-sheet positions. Common options include:

Sustainability / Green business loans

Purpose-built unsecured or secured loans for energy-efficiency works. Typical values start around £10,000 and run up into six figures. Terms range from 3–10 years. Pros: can fund a broad range of measures. Cons: rates and security depend on credit and lender policy.

Commercial refurbishment loans

Designed for property improvement; often larger facilities and may require a property charge. Suitable for major EPC uplift programmes across larger offices or blocks.

Asset finance

Used for equipment-specific purchases (e.g., heat pumps, EV chargers). Repayments align to equipment life; sometimes VAT-inclusive and structured for cashflow.

Retrofit / energy efficiency loans (specialist)

Specialist lenders and schemes assess energy savings and EPC uplift as part of underwriting. They may offer tailored terms where projected savings contribute to repayment capacity.

Remortgage or green mortgage options

For owner-occupied commercial property, refinancing can release funds for retrofit. Terms, LTV and pricing are dependent on property value and lender appetite.

PPAs and leasing for renewables

For solar PV, Power Purchase Agreements (PPAs) or leasing remove upfront cost and charge for energy. These are alternatives to loans rather than loan products.

Example use-case: an accountancy firm occupying a Victorian terrace improves insulation, installs LED lighting and air-source heat pumps. A typical retrofit loan might be £35–£60k, repayable over 5–10 years, sometimes supported by a charge on the property or personal/company guarantees depending on lender risk appetite.

What lenders will ask for — practical checklist for accountants preparing to apply

Prepare these documents to speed up matching and approval:

• Current EPC (baseline) and any recent energy surveys.
• Two or three detailed contractor quotes and contractor credentials.
• Business accounts (last 2–3 years), management accounts and VAT registration.
• Proof of property ownership or lease and landlord consent if tenant.
• Project schedule, expected completion date and estimated EPC uplift.
• Director ID and credit/background for limited companies (as required).

Quick tips:

• Get a pre-refurb EPC estimate from a qualified assessor if the final EPC is not yet available.
• Bundle works into one clearly costed project to make underwriting straightforward.
• Have a contingency sum (typically 5–10%) for unexpected costs — lenders like to see realistic budgeting.

Typical costs, timeframe and ROI expectations

The cost of upgrades varies by property size, age and scope. Typical ranges (illustrative only):

• LED lighting upgrade for small office: £3,000–£10,000.
• Insulation and fabric upgrades for medium office: £10,000–£40,000.
• Air-source heat pump installation (small commercial): £15,000–£50,000.
• Solar PV + inverter (small commercial rooftop): £10,000–£50,000.

Timeframe:

• Initial enquiry to lender match: hours to days.
• Underwriting and offer: typically 2–6 weeks (depends on security and complexity).
• Works completed and post-refurb EPC: weeks to months depending on contractors.

ROI is driven by energy bill savings, reduced maintenance and potential uplift in rental/value. Some investments may pay back in 3–7 years; others are longer-term asset improvements. Grants may be available regionally — speak to your matched broker about combining grants with loan funding.

Case study snapshot

An anonymised accountancy practice with a 120 sq.m. office upgraded from EPC F to D using a £35,000 retrofit loan. The project bundled insulation, LED lighting and a heat-recovery ventilation system. The lender required three quotes, a project timetable and an estimated post-works EPC. Works completed within 10 weeks; the firm benefits from lower energy bills and greater lettability/value.

Frequently asked questions

Can tenants apply for funding to meet MEES?

Yes — tenants can fund certain works but often need landlord consent. Lenders will request evidence of permission or a robust case that works are permitted under the lease.

Will improving EPC always mean MEES compliance?

An improved EPC helps meet MEES but check the statutory threshold and any local/regulatory updates. An EPC is one key metric among compliance steps.

Do enquiries affect my credit score?

No — submitting an enquiry through UK Business Loans does not affect your credit score. Lenders may perform credit checks later with your permission during formal application.

How quickly will I hear back from lenders?

Often within hours for an initial contact; full underwriting takes longer (typically 2–6 weeks depending on complexity).
