UK leasehold reforms and net-zero reversals risk chilling investment

The government has announced a package of measures aimed at reining in leasehold practices and trimming the burden of green subsidy costs on consumers, but the twin interventions have provoked sharp concern among long-term investors. Ministers will introduce a statutory cap on annual ground rents of £250, set to take effect from 2028, and envisage a legal path that drives those rents effectively to zero over a 40-year period. The leasehold reforms extend beyond the cap: new-build flats will largely be prevented from entering leasehold, existing leaseholders will be given a formal route to convert to commonhold, forfeiture as a sanction for certain missed payments will be removed, and a tougher enforcement regime plus greater service-charge transparency is promised to tackle abusive management. Separately, the government plans to change the indexation of renewables top-up payments from RPI to CPI and to shift recovery of some subsidy costs onto general taxation — moves presented as modest consumer relief. Institutional investors, pension schemes and renewables developers say the measures undermine predictable, contract-backed cashflows that underpin long-dated returns and financing models. Asset managers point to concrete exposures — mid-hundreds of millions in some cases — while advisers and consultants produce per‑billion invested cost estimates and warn of litigation and compensation claims that could be substantial. The practical challenges are acute: statutory amendments will need careful drafting to define transition mechanics, compensation arrangements and the interaction with existing contracts, and parliamentary scrutiny is likely to shape final detail. Market participants also note the cumulative effect of other recent interventions — wage mandates, expanded worker protections and tighter regulation — which together heighten perceptions of policy risk. The likely consequences are higher required returns for new projects, stretched financing for building safety and infrastructure maintenance, and a possibility of capital reallocation to jurisdictions judged to offer stronger contract continuity. Ministers argue reforms deliver tangible, popular benefits for homeowners and consumers while addressing exploitative practices; investors counter that retrospective changes to indexation and statutory rights amount to a reneging of expectations that will have measurable economic costs. How the government balances consumer relief, investor protections and the legal implementation of these changes will determine whether the moves produce short-term political gain at the expense of long-term investment and infrastructure delivery.
