## What is this about?

Long residential leaseholders may have statutory rights to extend leases or collectively enfranchise freeholds under the Leasehold Reform Act 1967 and the Leasehold Reform, Housing and Urban Development Act 1993 (as amended). Valuation and eligibility rules are technical; reform is ongoing.

## What is the core rule?

Under the 1993 Act, qualifying tenants of flats may seek a 90-year extension on top of the unexpired term at a peppercorn ground rent (s.56) or participate in collective enfranchisement of the freehold (Part I), subject to building and tenant qualification tests and landlord opposition grounds. Houses may qualify under the 1967 Act for freehold acquisition or extension. Premiums are calculated on statutory valuation assumptions (marriage value historically significant — check current reform position). Strict notice procedures (s.42 notices etc.) drive the timeline.

## What are the elements or test?

1. House or flat? Which statute?
2. Qualifying tenant / long lease / low rent tests as applicable?
3. Building qualification for collective claims?
4. Notice validity and counter-notice timing?
5. Valuation inputs and negotiation/tribunal route?
6. Any pending reform affecting marriage value or eligibility?

## Which authorities matter?

- **Leasehold Reform, Housing and Urban Development Act 1993 (as amended)** — Primary flat lease extension and collective enfranchisement code.
- **Leasehold Reform Act 1967 (as amended)** — House enfranchisement/extension rights.
- **Leasehold and Freehold Reform Act 2024 (phased commencement — many valuation reforms not yet fully in force as at mid-2026)** — Major reform statute intended to change enfranchisement valuation (including marriage-value treatment) and related rights. Do not apply uncommenced provisions; check current commencement orders before advising on premium calculation.

## How does this apply in practice?

This area is reform-active. Do not rely on pre-2024 valuation assumptions without checking commencement orders. Missing notice deadlines is a common negligence risk. Specialist valuers are usually essential.

## What are common pitfalls?

- Invalid s.42 notices
- Miscounting participating tenants for collective claims
- Using outdated marriage-value rules after reform commencement
- Ignoring intermediate landlords

## When would a practitioner use this?

Lease extension strategy; freehold purchase claims; conveyancing advice on short leases.
