An unusual little asset
When a flat is sold leasehold, someone retains the freehold. That freeholder receives a ground rent — historically nominal, a peppercorn or £50 a year — and holds the reversion: the right to the property itself when the lease eventually expires.
For investors, the attraction was a long-dated, index-linked, almost bond-like income with negligible management, secured on residential property and with a very long reversionary tail.
How it became a scandal
During the 2000s and 2010s, developers began selling houses — not just flats — as leasehold with ground rents that doubled every ten or fifteen years. A £250 ground rent doubling decennially becomes £8,000 within a lifetime.
These clauses made the properties unmortgageable and effectively unsellable. The Competition and Markets Authority took enforcement action against major developers, several of whom agreed to remove doubling clauses.
Legislative response
The Leasehold Reform (Ground Rent) Act 2022 reduced ground rents on most new residential long leases to a peppercorn. The Leasehold and Freehold Reform Act 2024 went further on enfranchisement and lease extension rights, and the government has consulted on capping existing ground rents — a move that would transfer value from freeholders to leaseholders directly.
This makes ground rents an unusually clear example of an asset class whose value is a function of legislation. Investors bought income streams that Parliament has been progressively legislating away, and pending consultations could reduce remaining values substantially.
Marriage value
When a lease falls below 80 years, extending it becomes markedly more expensive because the leaseholder must pay the freeholder a share of "marriage value" — the uplift created by combining the interests. Reform legislation has moved to abolish this, again shifting value from freeholder to leaseholder.
How you would actually trade it
Traded through specialist brokers and property auctions, usually in portfolios. Valuation depends on the ground rent level and review pattern, unexpired lease terms, and the statutory framework — which is exactly what is in flux.
Leaseholders have a statutory right of first refusal when a freeholder sells a block, which constrains how these can be marketed.
Anyone buying now is taking a position on where leasehold reform lands. That is a political forecast, not a property one.
What goes wrong
- Legislative risk dominates everything. Value can be reduced by statute without compensation.
- Reputational and regulatory scrutiny of freeholder conduct is intense.
- Enfranchisement. Leaseholders can collectively buy the freehold, ending the income.
- Illiquidity and a shrinking buyer pool as the legislative direction becomes clearer.
- Building safety liabilities have landed on some freeholders unexpectedly.
