ESG investment can enhance value and income

Many commentators appear to regard environmental and social upgrades to buildings as costs that impact their profits. Instead ESG should be recognised as a strategic investment that can enhance value and income plus ensure the asset has a future.

Correctly targeted, ESG improvements are value enhancing, increase tenant demand and strengthen risk management

First and foremost, improvement expenditure should be about enhancing assets. Whether that is improving energy performance or creating more productive environments these investments must be targeted to enhance and protect an asset’s relevance and its value. Sustainability is just good business – occupiers want buildings that are healthy and efficient – investors want to ensure their assets remain relevant and in demand for the long term. These forces are reshaping the definition of what makes a building prime. As regulation tightens and corporate occupiers raise their standards, properties that fail to keep pace risk obsolescence, higher voids and sudden future capex shocks.

Selective investment is critical

ESG investment can unlock value, but not every building can be economically improved. The UK’s retrofit challenge is immense – around 80% of the buildings that will exist in 2050 already stand today. The worst outcome is funding improvements piecemeal.  Isolated upgrades delivered without a plan, drain capital but fail to lift rents and don’t materially decarbonise or improve the occupational costs or the building environment.

Instead, owners need:

• Portfolio-level strategies – prioritising assets where returns justify capex
• Clear upgrade pathways – measured in emissions impact and value upside
• Regional awareness – economics differ dramatically between London and smaller markets and interventions must be tailored to reflect this reality
• Partnership approaches – Where currently uneconomic, it is sometimes possible that public-private collaboration can bridge the gap.

ESG investment cannot be a box-ticking exercise. It must be a coherent capital allocation strategy: focused on where it drives rent, reduces lifecycle cost, unlocks tenant demand and strengthens liquidity.

Premium pricing – because they are better buildings

A growing number of studies now link energy-efficient, ESG-aligned properties to higher rents, shorter voids and stronger valuations.

The market has decided sustainability is desirable and valuable.

• Greater energy efficiency = lower emissions and upgrade costs later
• Decarbonised mechanical systems = future-proofed cashflow
• Healthier spaces = more productive, more loyal tenants.

There remains nuance in operational cost savings. In the UK, electricity is still far more expensive than gas, and despite heat pumps delivering a multiple of the energy efficiency, without other targeted improvements occupational costs could increase.

Demand is already occupier-led

The case for strategic investment is reinforced by occupier trends. A rapidly growing share of corporates now operate under science-based sustainability targets, directly influencing where they choose to locate. For many, occupying poor-performing buildings would undermine their own ESG reporting and reputational standing.

More than just new build

Where landlords have delivered coherent refurbishments which improve the fabric, systems, and crucially wellbeing of buildings we are already seeing:

• Faster lease-up and shorter voids
• Higher headline rents
• Reduced incentives
• Greater lease renewal rates.

Given a choice many tenants are choosing ESG-aligned stock which can be delivered at a vastly smaller cost and carbon budget than new build.

Protecting financial futures and the planet’s future

Most commercial property is ultimately owned by pension funds and savers. Preserving long-term income and reducing stranded-asset risk protects people’s retirement security.

Simultaneously, climate risk is intensifying. Governments under fiscal strain are increasingly turning to carbon pricing and green taxation. Being ahead of regulation will avoid future cost penalties and reputational risk.

Conclusion

ESG investment isn’t about spending more. It’s about spending wisely. The winners will be those who treat sustainability as an investment, not a burden, creating resilient assets, stronger portfolios, and a better future for us all.
