Retrofit - Split Incentive: Who Pays, Who Benefits, Who Blinks First?

Retrofit remains structurally difficult for one simple reason: the party that pays is rarely the party that benefits. The Portfolio Strategy Tribe at CREAM UK 2026 examined this split incentive head-on - who carries the cost, who captures the value, and who moves first. Amid high upfront costs, planning uncertainty and shorter lease terms that compress the payback window, the discussion pointed towards a more pragmatic framing: not best-in-class, but "good enough" - buildings made the best they realistically can be, with customer experience the strongest influence on every decision.

The Split Incentive at the Heart of Retrofit

Retrofit decisions are shaped, above all, by the split incentive between landlords and tenants. Landlords generally fund the upfront capex, while tenants benefit from the lower running costs that result - a misalignment that sits at the heart of why so many otherwise sensible retrofits stall. Green leases and service charge mechanisms are being used to bring the two sides into alignment, but they remain inconsistent across the market and fall short of a reliable standard.

Viability Under Cost, Risk and Shorter Lease Terms

Viability is the recurring constraint. Retrofit economics are heavily influenced by cost, risk and planning uncertainty, and the question that underpins every decision - is the rent premium enough to justify the investment? - frequently lacks a confident answer. Shorter lease terms sharpen the problem further: when income is committed over a shorter horizon, the return on a significant upfront retrofit becomes harder to justify, compressing the window in which the investment must pay back. The shift towards flexibility on the occupier side and the capital intensity of retrofit on the owner side pull in opposite directions.

The "Good Enough" Question

In response, the Tribe noted a shift in ambition: away from chasing best-in-class outcomes and towards making buildings the best they realistically can be. This "good enough" framing acknowledges that not every asset warrants a gold-standard intervention, and that disciplined, proportionate upgrades may serve owners better than over-specification. Throughout, customer experience remained the biggest influence on decision-making, reinforcing that retrofit is ultimately judged by how a building performs for the people who use it.

Biggest Opportunity: Shared-Value Models Between Landlord and Tenant

The strongest opportunity lies in stronger landlord-tenant collaboration through shared value models. Where the two sides can turn energy and operational savings into a joint benefit - rather than a gain captured by one party at the other's expense - the split incentive begins to resolve itself. Beyond the immediate savings, there is meaningful long-term value uplift in ESG-aligned, efficient and future-proofed assets. The Tribe was clear, too, that the numbers are not the whole story: well-delivered buildings, run by good people with a genuine focus on experience, shift the dial in a way that specification alone cannot. Owners who can structure arrangements that share both cost and reward - and who pair them with strong operation and service - are best placed to unlock retrofits that would otherwise remain stuck, while positioning their buildings to stay competitive as standards tighten.

Biggest Challenge: Misaligned Costs and the Absence of Standards

The principal obstacle is the misalignment between who pays for retrofit and who benefits from it. This is compounded by the lack of standardised green lease structures across the UK market, which leaves each negotiation to be worked out from first principles, and by high upfront costs that make retrofit harder to underwrite and justify. Until the market develops more consistent mechanisms for sharing cost and value - and clearer evidence that the investment pays back - many owners will continue to hesitate, and the question of who blinks first will remain unresolved.
