How EPC Ratings Are Shaping Tenant Demand in 2026

Occupiers are increasingly factoring energy performance into their property decisions. This is not a marginal consideration. It is becoming central to how tenants evaluate potential premises.

Choosing a poorly performing building introduces uncertainty around operational costs, service charges, retrofit works, and capital expenditure. Efficient buildings, by contrast, offer greater stability, lower running costs, and reduced exposure to future regulatory requirements.

For landlords and asset managers, understanding this shift in tenant behaviour is essential. The buildings that let fastest and achieve the best terms are increasingly those with strong energy credentials.

Two buildings, one street, two entirely different futures: the gap between energy-obsolete stock and occupier-ready space has never been more visible or more consequential for landlords.

The Risk of Energy-Based Obsolescence

Buildings that fall behind in energy performance face a growing set of challenges that extend beyond regulatory compliance.

Longer void periods are one of the most immediate consequences. When tenants are actively avoiding inefficient buildings, the pool of potential occupiers shrinks, marketing periods extend, and void costs accumulate.

Reduced tenant demand often translates into weaker tenant quality. When a building struggles to attract interest, landlords may need to accept covenants they would not otherwise consider, or provide terms that would not be necessary for a better-performing asset.

Higher incentives are frequently required to secure lettings. Rent-free periods, fit-out contributions, and other inducements may need to increase to compensate for perceived weaknesses in the building. This directly reduces effective rental income.

Pressure on rental values can emerge when poor energy performance creates competitive disadvantage. If comparable buildings are achieving stronger terms because of better energy credentials, this creates downward pressure on what can be achieved for underperforming assets.

Taken together, these factors can create stranded asset risk. A building that cannot attract tenants, cannot achieve market rents, and requires significant investment to become competitive may face fundamental questions about its long-term viability.

What Tenants Are Looking For

Understanding what drives tenant decisions helps landlords position their assets effectively.

Lower operational costs remain a primary consideration. As energy prices have risen and volatility has increased, tenants are paying closer attention to the likely running costs of any building they occupy. Efficient buildings translate directly into lower operating expenses.

ESG alignment has moved from a nice-to-have to a necessity for many occupiers. Corporate sustainability commitments, carbon reduction targets, and reporting requirements all influence where tenants choose to locate. Occupying an inefficient building can undermine ESG performance and create challenges for sustainability reporting.

Service charge predictability matters more than many landlords appreciate. Tenants value stability in their occupancy costs. Buildings with poor energy performance often have more volatile service charges, and this uncertainty can be a significant factor in lease negotiations.

Reduced retrofit risk provides peace of mind. Occupiers are aware that MEES regulations are tightening. Choosing a building that already performs well reduces the risk of disruptive works during the lease term.

Impact on Reversionary Value

Reversionary value, the potential rental income when current leases expire, is increasingly affected by EPC performance.

Buildings with poor ratings may require works before they can be re-let. This creates both cost and timing uncertainty that must be reflected in valuations.

Investor appetite for poorly performing assets is declining. Institutional buyers and lenders are asking more detailed questions about energy performance, and buildings that cannot demonstrate credible compliance pathways may attract fewer bidders or require pricing adjustments.

Extended void periods at lease expiry directly reduce effective income. If a building is expected to take longer to re-let due to poor energy performance, this affects the value of the reversionary income stream.

Why a Proactive MEES Strategy Matters

Landlords who act now can reduce risk and improve competitive positioning. Several practical steps help strengthen portfolio performance.

Reviewing EPC ratings portfolio-wide provides essential baseline visibility. Understanding current positions enables informed prioritisation and helps identify assets that warrant earlier attention.

Targeting improvements strategically helps achieve meaningful progress efficiently. LED lighting, HVAC optimisation, BMS upgrades, and fabric improvements can all strengthen ratings, but the most effective approach varies by building.

Aligning EPC strategy with capital planning improves efficiency. Where refurbishment or maintenance works are planned, incorporating energy improvements can reduce overall cost and disruption.

Ensuring EPC modelling reflects true building performance is often overlooked. Many EPCs are based on default assumptions that do not reflect actual specifications. Providing evidence to support accurate modelling can improve ratings without physical works.

Conclusion

Energy performance is now a critical factor in tenant decision-making, financial planning, and asset strategy. The shift in occupier behaviour is established and accelerating.

Proactively managing EPCs helps reduce voids, attract quality tenants, and protect future rental income and reversionary value.
