The MEES Challenge: Why Strategic Funding for Upgrades is Critical Now

We know MEES is here. We also know what we need to do. But the real question is - where and how do we fund the upgrades that MEES requires? 

The UK commercial property landscape is rapidly evolving due to Minimum Energy Efficiency Standards (MEES). All non-domestic buildings in England and Wales now require at least an Energy Performance Certificate (EPC) rating of E to be legally let. By April 2030, this minimum requirement jumps dramatically to a B rating.

This creates an urgent funding challenge: approximately. This means over half a million UK properties need MEES-compliant upgrades within the decade. Properties that don't improve risk becoming "stranded assets" that cannot be leased, with an estimated £93 billion of commercial property value at stake. Property owners who fail to fund MEES upgrades face vacant buildings, regulatory fines, and significant reputational damage.

There's a silver lining, however. Buildings that have received funding for sustainability upgrades already command higher rents and capital values. Investors view MEES-compliant "green" buildings as less risky investments. Simply put, the cost of not funding necessary MEES upgrades will likely exceed the investment required – especially as inefficient properties face growing "brown discounts" in valuations.

“Both investors and occupiers seem to be mostly focussed on the brown discount. Obsolescence is priced into stock that is older, and buildings are taking longer to sell or to be rented when their ESG requirements and credentials are not up to scratch. From an ROI perspective, these elements come into play, although this varies across real-estate sectors. “ - Davis Malana, Director at Longshore Real Estate

The central question for property owners is: how to fund MEES upgrades across an entire portfolio? While traditional CapEx budgets are one option, the scale of work needed has property owners exploring innovative MEES funding models to spread costs and risks. These range from tenant cost-sharing agreements to specialised green loans and third-party energy service contracts specifically designed for funding building upgrades.

A strategic approach to funding MEES upgrades often combines multiple financing mechanisms throughout an asset's lifecycle. Let's explore the key options for financing MEES compliance – and how they can work together from acquisition through disposal – to meet requirements through smart investment.

Internal CapEx and Traditional Financing: The Foundation for Funding MEES Upgrades

Most MEES upgrade programs begin with internal capital expenditure or traditional financing. Many institutional owners set aside dedicated CapEx reserves or portions of annual budgets specifically for funding energy improvements required by MEES regulations.

This self-funding approach provides complete control: you fund the upgrades (such as HVAC systems, insulation, lighting) and retain all the energy savings and property value increases. At portfolio level, investors often incorporate MEES upgrade funding into their business plans, either including improvement costs when acquiring properties or scheduling funded retrofits during ownership.

Traditional bank financing can also support MEES investments or in fact, any sustainability aligned framework such as CRREM – for example, by refinancing an asset after upgrades to recover expenses, or by including a specialised CapEx facility in loan agreements specifically for MEES upgrade projects.

“ Lenders now ask if we’re in line with CRREM within the term of the loan. If the answer’s no, they might add five basis points—or just walk away. We also see this on the other side in transactions where buyers knock millions off a building’s price if we can’t show it is CRREM-aligned. The piece of the puzzle that’s missing is where valuations sit in this. ” — William Ray, Head of Sustainability at CLS Holdings PLC

However, relying solely on internal funds to finance MEES compliance has clear limitations. The scale of upgrade costs can stretch capital budgets, especially for diverse portfolios with many underperforming buildings. Committing equity to building systems is increasingly viewed as an inefficient use of capital. There's also an opportunity cost – funds used for MEES upgrades could potentially be deployed elsewhere for acquisitions or other value-add projects.

This is why property owners are increasingly turning to external funding solutions beyond traditional approaches. By leveraging specialized financing models for MEES upgrades, you can accelerate energy improvements while preserving your balance sheet strength.

Green Leases: Collaborative Funding for MEES Upgrades

Green leases offer a practical approach to financing MEES upgrades, and they also solve the classic landlord-tenant "split incentive" problem that often hampers funding for building improvements. A green lease includes specific clauses that commit both parties to collaborate on sustainability measures, enabling cost-sharing arrangements for MEES compliance work.

For example, a landlord might fund the installation of efficient LED lighting or a modern HVAC system to improve EPC ratings, and the tenant agrees to contribute through slightly higher service charges or rent – which is offset by their lower energy bills. In other cases, the tenant might directly fund equipment investments (like on-site renewables) with the landlord's approval. The key is that the lease fairly allocates both the financial responsibilities and benefits of MEES-related improvements.

“ By intelligently carving out what looks like a massive cost, for example if you go and revisit a PPM (Planned Preventative Maintenance programme) where effectively the gas boiler replacement just works, it’s in the budget like for like. It's about using the cost and those frameworks to build in the alternatives and then spread that cost out. Some of it will be CapEx but the rest will be operational. Making those changes makes things like tenant recharging more accurate. The platforms are there, they're ready to cope with it and I think we can evolve as an industry. ” — Paul Stepan, Head of Sustainability Consultancy, EMEA at JLL

Green leases have gained significant traction in the UK as a funding mechanism for MEES upgrades. By formalising how savings and costs are shared, they provide a structured way for landlords and tenants to both benefit from efficiency improvements. Tenants get more comfortable, lower-cost space; owners secure improved EPC ratings and property value without bearing the full expense of funding upgrades alone.

Many institutional landlords now incorporate green lease clauses at lease renewal or signing. These range from data-sharing agreements (to track energy performance) to fit-out standards and cost recovery provisions. For instance, owners may stipulate that capital improvements which reduce utility consumption can be recouped through the service charge (sometimes called an "energy saving fee").

Opportunities for Funding MEES Upgrades: Green leases can unlock retrofit projects that wouldn't proceed under standard leases due to funding constraints. They strengthen landlord-tenant relationships around a shared commitment to MEES compliance, which can enhance tenant retention. By aligning interests, from a zero-sum problem into a collaborative solution.

Considerations for MEES Funding: Drafting and negotiating green leases requires careful planning. Not all tenants will readily agree to shared funding without seeing proof of future savings. Timing is also crucial – landlords might need to wait for a lease break or renewal to introduce green clauses, which could delay urgent MEES upgrades.

Sustainability-Linked Loans: Preferential Funding Terms for MEES Compliance

Traditional loans are increasingly being transformed into sustainability-linked loans (SLLs) specifically designed to fund MEES upgrades and support real estate ESG goals. An SLL adjusts its pricing or terms based on whether you achieve specific sustainability targets, including MEES compliance metrics.

An SLL is more flexible than a standard green loan, where proceeds must fund a specific green project. Borrowers can use an SLL for general corporate or acquisition purposes, but the interest rate moves up or down depending on whether you meet predefined ESG metrics. For MEES compliance funding, typical targets might include improving a building's EPC rating to meet or exceed regulatory requirements, obtaining a green building certification (like BREEAM Excellent), or reducing the property's carbon emissions by a set amount.

Opportunities for MEES Funding: SLLs can effectively lower your cost of capital for MEES upgrade projects when targets are met. They signal to stakeholders (banks, investors, tenants) that you're committed to compliance through strategic funding. From a financial standpoint, SLLs allow you to secure financing for an asset (often at acquisition or refinancing) with built-in accountability for executing necessary MEES upgrades. Hitting the loan's EPC targets not only ensures compliance but also earns you a discount on interest, improving overall financial performance.

Considerations for Funding MEES Upgrades: You must be confident in your ability to deliver the promised improvements, otherwise, an SLL can backfire if targets are missed and financing costs rise. There's also administrative work involved: tracking and reporting progress on Key Performance Indicators (KPIs) is essential to prove compliance to lenders. The choice of ambitious but achievable targets is critical when using this funding approach.

Some loans offer only small pricing adjustments for success or failure, so the direct financial gain might seem modest. However, even a slight margin reduction can be meaningful on large loans, and the reputational benefits of meeting SLL targets while achieving MEES compliance can be significant.

ESCOs and Performance Contracts: Off-Balance Sheet Funding for MEES Upgrades

Another innovative funding route for MEES upgrades is partnering with an Energy Service Company (ESCO) through a performance contract. Under an Energy Performance Contract (EPC) arrangement, a third-party ESCO covers the upfront cost of identified retrofit measures needed for MEES compliance and is paid back over time from the energy cost savings achieved.

This model transforms a capital project into a service: as building owner, you incur little or no upfront CapEx for MEES upgrades. Instead, you make regular service payments designed to be less than or equal to your utility bill savings, creating a net neutral or positive cash flow. Crucially, the ESCO provides a performance guarantee – if the agreed energy savings don't materialise, the ESCO absorbs the shortfall, often by compensating you or reducing fees.

Opportunities for Funding MEES Upgrades: The ESCO route can achieve upgrades, effectively transforming what would have been CapEx into an operating expense spread over years. This preserves your capital for other uses and avoids large one-time hits to cash flow when funding MEES requirements.

This approach is especially useful for compliance-driven retrofits that may not have an attractive ROI purely on rent or value – the energy savings pay for the project, so you can justify doing it to meet MEES without expecting tenants to pay more. Another benefit is risk transfer: performance risk is borne by the ESCO, which must ensure the promised savings materialise.

For portfolio owners, ESCOs can handle multiple sites as a coordinated MEES upgrade program, bringing technical expertise and potentially bulk procurement discounts. When many assets need upgrades, partnering with an ESCO can accelerate implementation across your portfolio.

Considerations for MEES Funding: Not every MEES retrofit can be fully financed through energy savings alone. Deeper retrofits (like major insulation or window replacements) have long paybacks that might exceed a reasonable contract term. ESCOs tend to focus on measures with clear, quick returns (lighting, heating systems, controls); you might still need to self-fund more extensive works to reach a high EPC rating.

You can combine approaches – for instance, use an ESCO for the quick wins (to get from a G to an E rating), then invest your own capital for the remaining upgrades to reach a B. While off-balance sheet treatment is attractive when funding MEES upgrades, accounting standards are evolving and not all deals qualify – so your finance team should assess implications carefully.

Government Incentives and Guarantees: Supplemental MEES Funding Support

The UK government and local authorities offer various incentives that can supplement your MEES upgrade funding strategy, although the commercial sector has fewer direct subsidies than residential retrofit programs. Several policy tools and incentives can support your MEES funding plans:

Tax Incentives for MEES Upgrades

The UK has used its tax code to encourage capital investment in energy-saving equipment. Until recently, the Enhanced Capital Allowance scheme allowed 100% first-year tax relief on qualifying energy-efficient plant. Now a full expensing regime (temporarily in place) lets companies deduct 100% of equipment costs immediately. Investing in efficient building systems as part of MEES compliance can therefore yield substantial tax savings to offset upfront funding needs.

Additionally, there are targeted reliefs such as extended business rates exemptions for green building improvements (e.g., adding solar panels or heat pumps will not increase a commercial property's rateable value through 2035).

Grants and Rebates for MEES Compliance

Direct grants for commercial MEES upgrades are limited, but some schemes exist. SMEs and certain property types can access grants for specific technologies. Local authorities and devolved governments also have programs – for example, the Scottish Government has offered interest-free loans for SME energy efficiency, and the provides affordable finance for energy projects in London, including MEES-related improvements.

Government-Backed Loans for Funding MEES

The government can spur private investment by de-risking loans for MEES retrofits. The has a mandate to finance net-zero projects and could co-invest or guarantee loans for large-scale building upgrade programs.

Future Policy Signals for MEES Funding

The government's ongoing interest in is worth noting for future MEES funding strategies. PLF would attach the repayment of a retrofit loan to the property itself (via a local tax bill) rather than the owner, allowing longer-term financing that stays with the building upon sale. If introduced, this could unlock 100% financing for deep retrofits needed for MEES compliance, repaid over 15-20 years.

Opportunities for MEES Funding: Government incentives, where available, are essentially "free money" or risk reduction for investors – they can dramatically improve project economics when funding MEES upgrades. Taking advantage of tax reliefs and grants can shorten payback periods and increase ROI on energy projects required for compliance.

Considerations for MEES Funding: Relying on government schemes can be risky since policies change with political winds. Asset managers should utilize incentives as a bonus rather than the sole plan for funding MEES work. Furthermore, any arrangement involving public money may come with additional scrutiny or reporting requirements.

European and ESG Funding: Alternative Capital Sources for MEES Upgrades

Beyond formal government programs, there's a growing pool of private and institutional capital specifically targeting sustainable real estate improvements like MEES upgrades. ESG-focused funds, Green bonds, and European financial instruments offer alternative avenues to finance compliance work:

Green Bonds and Debt Funds for MEES Upgrades

Many real estate companies are turning to capital markets by issuing green bonds – debt instruments where proceeds are earmarked for environmentally beneficial projects like MEES-related building retrofits. UK REITs and property firms have issued green bonds to fund office refurbishments and portfolio upgrades, attracting institutional investors drawn to the stable, long-term cash flows of energy efficiency projects.

Similarly, green real estate debt funds are actively looking to lend on MEES retrofit projects or efficient buildings. These funds might offer better terms or higher loan-to-value ratios for projects meeting their ESG criteria.

Private Equity and ESG Impact Investors for MEES Funding

On the equity side, specialist "brown-to-green" investment funds partner with owners to finance MEES upgrades. Some European private equity real estate funds specifically seek out buildings with low EPCs to buy or joint-venture, deploy capital to improve them to MEES standards, and then capture the value increase at sale.

An existing owner could leverage such capital by selling a stake in an asset to an ESG impact investor who brings retrofit funds and expertise. This approach spreads the financial burden and risk of a deep retrofit required for MEES compliance with a partner.

Opportunities for MEES Funding: The rise of ESG investing means more capital is chasing sustainable assets than ever before. By demonstrating a clear MEES upgrade plan and alignment with frameworks like the EU Taxonomy, UK asset managers can attract this specialized funding on favorable terms.

Partnering with external ESG funds or using green bonds can enhance your reputation and appeal to shareholders – effectively turning a compliance exercise into a value-creation story. Accessing multiple sources (debt, equity, grants) and combining them can significantly reduce your net cost for MEES upgrades.

Considerations for MEES Funding: Engaging with external capital brings additional complexity. Green bond issuers must commit to ongoing reporting and risk accusations of "greenwashing" if outcomes fall short. Private co-investors will expect returns commensurate with risk, which can mean giving up some future upside or control of your MEES strategy.

Lifecycle Approach to Funding MEES Upgrades

To maximise effectiveness, asset managers should take a lifecycle view of MEES funding – employing different financing strategies at acquisition, during management, and at disposal:

Acquisition Phase MEES Funding: 

The journey often begins at purchase. When evaluating an acquisition, rigorously assess the target's EPC rating and the required MEES improvements. If a building is below standard, negotiate a price discount to account for necessary upgrade funding.

Line up financing to execute the MEES retrofit as part of your acquisition plan – for example, arrange a sustainability-linked loan that provides funds for purchase and includes commitments to perform upgrades. Map out your capital plan for reaching compliance: what portion will come from internal budget, what might come from a green loan or ESCO. Incorporating these funding plans from day one ensures financing is in place when needed for MEES work.

Asset Management MEES Funding Strategy: 

During ownership, focus on executing retrofit projects and actively managing financing. Schedule MEES upgrade works to align with lease events to minimize disruption – this also provides an opportunity to introduce green lease terms for shared funding arrangements.

Deploy a combination of funding sources: use internal CapEx for low-cost quick wins, utilize an ESCO contract for more capital-intensive system replacements, and perhaps draw on a capex facility in your loan for interim funding of MEES requirements. If your portfolio has sustainability-linked debt, ensure covenants are being met through regular performance checks. This is also the time to claim any government incentives available for MEES upgrades.

Disposal/Exit Phase and MEES Funding Recovery: 

When selling assets, ensure the benefits of funded MEES upgrades are realized. A building with a high EPC (B or above) will command a stronger price – potentially yielding a When preparing for sale, highlight the improvements funded for MEES compliance and consider obtaining an updated valuation that reflects reduced running costs and future regulatory alignment.

Any financing mechanisms in place need careful handover: if there's a long-term ESCO contract funding MEES improvements, can the new owner assume it easily? For loans, an SLL may be refinanced at sale or could remain if the buyer takes over the obligations.

Throughout this lifecycle, the sequencing of MEES funding is crucial. You might start with a short-term bridge loan to acquire a property, use an ESCO to fund immediate MEES improvements, then refinance into a long-term green loan once the asset is stabilized as a green building. Or you might initially fund MEES upgrades from equity and then refinance after works are completed to recover costs at a lower interest rate.

Strategic Funding Approaches for MEES Compliance

Meeting MEES obligations across your portfolio is undeniably a significant financial undertaking, but it's one you can approach with confidence by leveraging the right mix of funding strategies specifically designed for energy efficiency upgrades.

Strategic planning for funding MEES upgrades – considering all stages of an asset's life and all sources of capital – allows you to spread costs, reduce risks, and uncover value in the process. Your toolkit for funding MEES compliance is diverse: align interests via green leases, secure favorable loan terms through sustainability-linked debt, offload upfront costs onto ESCO partners, or tap into public incentives and global ESG capital. These funding tools work best in combination.

The transition to energy-efficient, MEES-compliant buildings is both a regulatory requirement and an opportunity. Those who move early and deploy innovative funding strategies to upgrade their assets will not only avoid the penalties facing non-compliant buildings; they'll also be positioned to deliver modern, resilient spaces that meet rising environmental expectations.

The message is clear: take a proactive, creative approach to funding MEES retrofits. By doing so, you'll safeguard portfolio value, access new pools of capital, and contribute to broader climate goals. Having a well-crafted funding strategy for MEES improvements is rapidly becoming a hallmark of smart asset management.

The path to MEES compliance may be complex, but with the right blend of funding mechanisms and financing innovations, it leads to sustainable returns – both financially and environmentally – in the years ahead. In a landscape where "it will pay to be on the front foot and invest in green buildings now", strategic funding for MEES upgrades could be your most valuable tool for future-proofing your real estate assets.

MEES Funding FAQ: Common Questions About Financing Building Upgrades

What is the deadline for funding MEES upgrades?

For non-domestic buildings in England and Wales, you must have at least an E rating to legally let property now, with the minimum standard rising to a B rating by April 2030. This creates a clear timeline for securing funding for necessary upgrades.

Can tenants be required to contribute to MEES upgrade funding?

With properly structured green leases, yes. Many commercial leases now include provisions for cost-sharing of energy efficiency improvements, allowing landlords to recover some MEES upgrade costs through service charges or "energy saving fees" when tenants benefit from lower utility bills.

Are there tax advantages for funding MEES improvements?

Yes. The UK tax system offers several incentives, including capital allowances for energy-efficient equipment and temporary "full expensing" provisions that allow 100% of certain capital costs to be deducted against taxable profits in the year of expenditure, improving cash flow for MEES upgrade projects.

How can I fund MEES upgrades without affecting my balance sheet?

Energy Performance Contracts with ESCOs can potentially be structured as off-balance sheet arrangements, where the ESCO funds and implements the improvements while you pay for the service over time from energy savings. This preserves capital for other investments while achieving compliance.
