Lease Extension vs Freehold Purchase: The Decision-Architecture for Leaseholders of Houses and Flats Under the Post-LFRA-2024 Statutory Regime

If you own a leasehold flat with 70-99 years remaining on the lease, you have two statutory routes: extend the lease for a peppercorn-rent 990-year term under the Leasehold Reform, Housing and Urban Development Act 1993 Chapter II, or join with neighbours and buy the freehold under Chapter I. If you own a leasehold house, the parallel choice sits under the Leasehold Reform Act 1967: enfranchise (acquire the freehold) or extend the lease at a modern ground rent. The Leasehold and Freehold Reform Act 2024 recalibrates both choices by abolishing the 2-year qualifying-ownership period, abolishing marriage value, extending the LRHUDA 1993 statutory new-lease term to 990 years, and enabling regulation of the statutory deferment rate.

This page is the decision-architecture for the choice between the two routes.

Two parallel statutory regimes: LRA 1967 (houses) and LRHUDA 1993 (flats)

The English-and-Welsh leasehold reform statutes operate in parallel for the two main residential building types. Each regime offers the qualifying long-leaseholder both an extension right and an acquisition right; the strategic question (extend vs acquire) is symmetric across the two, but the operative mechanics differ.

Houses under LRA 1967

The 1967 Act gives the qualifying long-leaseholder of a house both an enfranchisement right (acquire the freehold) under s.1 + s.9 and an extension right (50-year extension at a modern ground rent) under ss.14-15. The two rights sit under one Act but they are not symmetric in practice: the LRA 1967 extension at modern ground rent is rarely chosen against LRA 1967 enfranchisement, which extinguishes the leasehold structure altogether at a typically modest premium. For most house-leaseholders, LRA 1967 enfranchisement is the default; the LRA 1967 extension is a niche residual route.

Key LRA 1967 sections: s.1 (tenants entitled to enfranchisement or extension); s.2 (definition of 'house'); s.3 (definition of 'long tenancy'); s.5 (general claim provisions); s.9 (purchase price for enfranchisement, valuation formula); s.14 (obligation to grant extended lease); s.15 (terms of tenancy on extension).

Flats under LRHUDA 1993

The 1993 Act offers flat-leaseholders two parallel routes. Chapter I (ss.1-38) is collective enfranchisement: a group of qualifying tenants in a block buy the freehold of the building. Chapter II (ss.39-62) is individual lease extension: a single qualifying tenant extends their lease for 990 years (post-LFRA-2024; previously existing-lease plus 90 years) at a peppercorn ground rent, against payment of a statutory premium.

Key LRHUDA 1993 Chapter I sections: s.1 (right to collective enfranchisement); s.13 (initial notice by qualifying tenants); s.32 + Schedule 6 (price determination). Key Chapter II sections: s.39 (right of qualifying tenant of flat to acquire new lease); s.42 (initial notice); s.56 (obligation to grant new lease). The 990-year term is set by LFRA 2024 amendment to s.56 (commencement-dependent; verify in force at the date you act).

What LFRA 2024 changed (and what is still pending)

The Leasehold and Freehold Reform Act 2024 Part 2 contains four headline changes to the extension-vs-freehold decision.

1. 2-year qualifying-ownership period abolished. A buyer can now extend or join an enfranchisement immediately on completion, removing the buy-and-wait friction. This affects timing in conveyancing chains: a leaseholder selling a short-lease property no longer needs the buyer to wait 2 years before claiming, so the lease-extension premium can be negotiated into the sale price more cleanly.
2. LRHUDA 1993 Chapter II statutory new-lease term extended to 990 years. Previously the new lease was the existing lease plus 90 years (so a 75-year residual lease became 165 years on extension). Post-commencement, the new lease is a fresh 990-year term from existing expiry. The change materially closes the lender, disposal, and reversionary-value gap between the extended-lease and freehold-acquisition outcomes for flats.
3. Marriage value abolished. The valuation uplift triggered at the 80-year unexpired-term cliff (the 'cliff' that made 81 years the historic deadline for cost-efficient extensions) is removed. The premium-reduction effect is most material on sub-80-year leases. Hope value (the uplift achievable by selling individual extensions to non-participating leaseholders) is also abolished for collective enfranchisement under Chapter I.
4. Regulated deferment and capitalisation rates. The Secretary of State can regulate the deferment and capitalisation rates used in the statutory valuation. The current case-law baseline rate (5% deferment, from Sportelli v Cadogan [2007] EWCA Civ 1042) can be replaced by a statutory rate set by Order. The replacement rate is commencement-dependent.

LFRA 2024 commencement is phased through 2026-2027. Some Part 2 provisions are commenced; others require secondary legislation that has not yet been made. Pre-LFRA-2024 valuation rules continue to apply to claims notified before the relevant commencement date. Before relying on any specific change above, verify the current commencement status against the gov.uk commencement-orders register and the consolidated text on legislation.gov.uk.

How premiums are calculated under each regime

The two regimes use different statutory formulas but rest on the same three valuation components, discounted at a statutory deferment rate.

LRHUDA 1993 Chapter II individual lease extension (Schedule 13)

• Term value. The capitalised value of the ground rent payable to the freeholder for the remaining term of the existing lease. For a peppercorn ground-rent lease the term value is nil. For an escalating ground-rent lease (a doubling clause every 25 years, for example), the term value can be substantial.
• Reversion value. The deferred value of the freeholder's right to repossess the demised premises on lease expiry, discounted from the expiry date back to the valuation date at the statutory deferment rate.
• Marriage value. Historically: 50% of the uplift in combined value when freeholder and leaseholder interests merge, triggered below the 80-year unexpired-term cliff. ABOLISHED post-LFRA-2024 commencement.

LRHUDA 1993 Chapter I collective enfranchisement (Schedule 6)

• Term plus reversion (as above for each flat in the building).
• Plus a share of any non-participating leaseholder's lease premium reversion.
• Plus historic marriage value (ABOLISHED) and hope value (ABOLISHED for collective enfranchisement under LFRA 2024).

LRA 1967 enfranchisement of houses (s.9)

A three-strand valuation framework (s.9(1) lower-value houses; s.9(1A) higher-value houses; s.9(1C) very-high-value houses). The framework includes a 'site value' assessment for lower-value houses and a market-value assessment for higher-value houses. The detail is house-specific and requires a specialist enfranchisement valuer.

SDLT on each route

The SDLT treatment varies sharply between extension and acquisition.

Statutory lease extension under LRHUDA 1993 Chapter II

Treated as surrender-and-regrant under FA 2003 Schedule 17A paragraph 9. The new lease is a chargeable land transaction; the chargeable consideration is the premium plus the net present value of rent under the new lease. Peppercorn rent gives nil NPV, so the SDLT base is the premium. The para 9 overlap-relief credit applies (rent under the new lease for the overlap period is reduced by the rent that would have been payable under the old lease), but with peppercorn rents the credit reduces nil to nil, operationally invisible. The 5% additional-dwellings surcharge under FA 2003 Schedule 4ZA bites on premiums of £40,000 or more where the leaseholder already owns another residential property.

House enfranchisement under LRA 1967

A standard residential SDLT charge on the freehold purchase consideration. Slice rates apply (0% to £250,000, 5% to £925,000, 10% to £1.5m, 12% above) plus the 5% additional-dwellings surcharge under Schedule 4ZA if the buyer already owns another residential property.

Collective enfranchisement under LRHUDA 1993 Chapter I

The special calculation under FA 2003 section 74: total consideration divided by the number of qualifying flats to derive a per-flat fraction; standard residential SDLT rates applied to the per-flat fraction; the resulting tax multiplied back up by the number of flats. The mechanic typically delivers materially less SDLT than applying full rates to the aggregate consideration because the per-flat fraction often falls inside the £250,000 nil-rate band. The Schedule 4A 17% flat rate may apply where the per-flat fraction exceeds £500,000 and a corporate envelope is in use.

Three worked examples

Example 1: London zone-2 leasehold flat, individual extension under LRHUDA 1993 Chapter II

Leasehold flat, 75-year residual lease, peppercorn ground rent. Leaseholder owns no other property. Statutory extension premium post-LFRA-2024 (marriage value abolished) £55,000.

• SDLT chargeable consideration: £55,000 premium plus nil NPV of peppercorn rent. Slice rates: £55,000 falls inside the £250,000 nil-rate band. No HRAD surcharge (only residential property the leaseholder owns).
• SDLT: nil.
• All-in cost: roughly £70,000 with legal and valuation costs.

Example 2: Same flat, leaseholder owns a buy-to-let elsewhere

Same flat, same premium £55,000. Leaseholder already owns a buy-to-let property.

• SDLT chargeable consideration: £55,000.
• HRAD surcharge applies (premium at least £40,000 and the leaseholder owns another dwelling): 5% on £55,000 = £2,750.
• All-in cost: roughly £73,000.

Example 3: Collective enfranchisement of an 8-flat block, FA 2003 s.74

Total consideration £1,200,000 across 8 qualifying flats.

• Per-flat fraction: £1,200,000 / 8 = £150,000.
• Standard residential SDLT on £150,000: nil (inside the £250,000 nil-rate band).
• Tax multiplied back up by 8: nil multiplied by 8 = nil.
• SDLT: nil.
• By contrast, applying standard residential rates to the aggregate £1,200,000 (without s.74) would have produced approximately £63,750 of SDLT.

The s.74 mechanic is the reason collective enfranchisement is, in tax terms, often substantially more efficient than the headline price suggests. Verify the rate slices and surcharge framework against the most recent Finance Act before relying on the numbers above.

Practical control, ground-rent, lender, and disposal differences

The choice is not purely a numbers calculation. The two routes produce structurally different outcomes for ground rent, building management, lender treatment, and onward disposal.

Ground rent

Freehold acquisition extinguishes the ground rent permanently: there is no longer a freeholder to whom rent is paid. The 990-year LRHUDA 1993 extension reduces ground rent to a peppercorn (a nominal sum, typically not actually demanded) for the new term, achieving the same economic outcome for the next millennium without removing the freeholder from the structure.

Building management

Freehold acquisition (via collective enfranchisement) places the participating tenants in control of building management. Service charges, major-works decisions, and managing-agent appointments become a leaseholder-collective matter, typically structured through a nominee freehold-owning company or a right-to-manage-equivalent arrangement. The 990-year extension leaves the management structure unchanged: the original freeholder remains, the service-charge framework continues, and the leaseholder gains 990 years of security without governance responsibility.

Lender treatment

Most mortgage lenders treat both routes as resolving the short-lease concern. Some premium-market lenders prefer share-of-freehold (the collective-enfranchisement product) over extended-lease where a choice is available; in mid-market lending the two routes are typically equivalent. Lenders care about the unexpired term at acquisition; both routes deliver effectively the same comfort.

Onward disposal

Share-of-freehold property historically commands a small price premium in flat markets where the buyer values long-term management control. Extended-lease property at 990 years residual has converged closely on share-of-freehold pricing as the 990-year term reduces the lender and reversion concerns. The historic 'short-lease discount' that drove the 81-year-cliff extension framing has been substantially flattened by LFRA 2024.

The decision grid

The following decision-grid summarises when each route typically wins on the merits, holding cost and process aside.

Factor	Extension typically wins	Freehold acquisition typically wins
Building type	Flat with weak neighbour coordination	Flat with strong neighbour coordination; any house
Planning horizon	20-50 years (peppercorn term solves the lender and ground-rent problem)	Indefinite (governance and ground-rent extinction)
Management appetite	Leaseholder prefers landlord-managed	Leaseholder wants self-governance
SDLT efficiency	Small premium (most premiums under £250,000)	Collective enfranchisement with s.74 per-flat fraction often nil
Hope-value capture	Not available	Available (future scheme variations on the freehold)
Coordination cost	Unilateral; low	Group coordination required; meaningful

CGT, IHT, and ATED interactions

CGT

The leaseholder pays no CGT on extension or enfranchisement: the consideration flows outward (leaseholder pays the freeholder), there is no chargeable disposal on the leaseholder's side. The freeholder has a chargeable disposal under TCGA 1992. For an individual freeholder, residential CGT rates (18% basic-rate band; 24% higher-rate band) apply to the gain. For a corporate freeholder, corporation tax on the chargeable gain applies. The freeholder's CGT base cost in the freehold reversion is calculated under TCGA principles; the disposal proceeds are the premium received.

IHT

The leaseholder converts cash to an interest in land: no immediate IHT consequence. The post-extension lease has a higher reversionary value than the pre-extension lease, which sits on the leaseholder's balance sheet but inside their normal IHT estate. For leaseholders running an IHT plan, the extension or enfranchisement does not by itself trigger a transfer of value, but the higher post-transaction value affects subsequent gift, trust, or succession planning.

ATED

For a corporate-held leasehold residential dwelling of £500,000 or more, the post-extension or post-enfranchisement valuation may push the property into a higher ATED band on its next ATED revaluation date. Companies running portfolios in personal-use envelopes should diary the next ATED valuation date and run the post-extension valuation against the band thresholds.

Timeline, cost loading, and the tribunal route

The two regimes share a procedural pattern. The leaseholder serves an initial notice (LRA 1967 s.5 for houses; LRHUDA 1993 s.13 for collective enfranchisement of flats; LRHUDA 1993 s.42 for individual flat extension). The freeholder serves a counter-notice. The parties negotiate the premium; if they cannot agree, the matter goes to the First-tier Tribunal (Property Chamber) for determination.

Typical timelines: individual flat extension 6-12 months; collective enfranchisement 9-18 months; house enfranchisement 6-12 months. The leaseholder pays the freeholder's reasonable legal and valuation costs in addition to the premium (capped under the post-LFRA-2024 costs framework), plus the leaseholder's own legal and valuation costs. All-in cost loading is typically 1.3-1.8 times the headline premium.

The tribunal route adds 3-6 months and an additional cost layer where the parties cannot agree the valuation. In practice, the threat of tribunal often produces an agreed valuation within a defensible range; tribunal hearings on lease-extension valuations are heavily evidence-driven, and an early specialist valuation strengthens the leaseholder's negotiating position.

What to do

For any leaseholder weighing the two routes, the right discipline is:

1. Identify the regime. Flat or house; LRHUDA 1993 or LRA 1967; statutory long lease (more than 21 years originally granted); not previously statutorily extended; not in an exempt building.
2. Run the premium estimate under both routes. Use a specialist enfranchisement valuer. For flats: individual extension premium plus collective enfranchisement premium per flat. For houses: enfranchisement premium under LRA 1967 s.9.
3. Run the SDLT under both routes. Extension: Sch 17A para 9 on the premium, plus HRAD if applicable. Acquisition: standard residential SDLT (houses) or s.74 per-flat fraction (collective enfranchisement). Read against the existing site page on SDLT on leasehold extension for the rate-mechanics deep dive.
4. Map the freeholder's-side CGT. Where the leaseholder's negotiating position depends on freeholder appetite to settle, an awareness of the freeholder's chargeable gain is useful.
5. Verify LFRA 2024 commencement status. The 990-year term, the marriage-value abolition, the hope-value abolition for collective enfranchisement, the deferment-rate regulation, and the 2-year-qualifying-period abolition are commenced or pending in stages through 2026-2027. Check the gov.uk commencement-orders register and the legislation.gov.uk consolidated text before relying on any specific change.
6. For flats, gauge neighbour coordination. Collective enfranchisement requires at least 50% of qualifying tenants. Where coordination is weak, individual extension is the pragmatic default.
7. Build the documentary file. Initial notice, counter-notice, valuation evidence, SDLT computation, completion documentation, and post-completion ATED revaluation diary for corporate-held dwellings.
