This guide sets out — in plain English — the statutory framework, procedure, evidence and tactical decisions involved in how to serve a section 42 notice — lease extension. It is written for leaseholders, RTM directors, managing agents and small landlords who need to prepare a Property Chamber case to the same standard a solicitor would.
What you need to know
- Read the lease first — it defines what is even in scope for the statutory tests.
- Split contract (lease) arguments from statute (reasonableness / procedure) arguments.
- Costs discipline — plead s.20C, para 5A Sch 11 and Rule 13 at issue, not at closing.
- Prepare a paginated bundle and a Scott Schedule; the tribunal decides on evidence.
Statutory framework
- s.18 Landlord & Tenant Act 1985 (definition of service charge)
- s.19 Landlord & Tenant Act 1985 (reasonableness)
- s.20 Landlord & Tenant Act 1985 (consultation)
- s.20B Landlord & Tenant Act 1985 (18-month rule)
- s.20C Landlord & Tenant Act 1985 (costs order)
- s.21 Landlord & Tenant Act 1985 (summary of costs)
Statutory framework
Collective enfranchisement and lease extension of flats sit under the Leasehold Reform, Housing & Urban Development Act 1993 (flats) (heavily amended by Leasehold & Freehold Reform Act 2024). Houses use Leasehold Reform Act 1967 (houses).
Key concepts:
- Qualifying tenant — long lease originally granted for >21 years.
- Premium components — term value + reversion value + (for pre-reform claims) marriage value where the unexpired term is under 80 years.
- Deferment rate — the discount applied to the reversion, historically 5% for flats / 4.75% for houses (see Cadogan v Sportelli [2008] UKHL 71), now under review.
- Relativity — the ratio of leasehold to freehold value, contested via graphs (Mundy v Trustees of Sloane Stanley Estate [2018] EWCA Civ 35).
What Leasehold & Freehold Reform Act 2024 changes
- Abolition of the 2-year ownership rule.
- Removal of marriage value.
- Standard 990-year extensions at peppercorn ground rent.
- New prescribed cap rates set by Secretary of State.
- Non-residential threshold raised from 25% to 50% for collective claims.
Commencement is staggered; not every provision is in force at the date of the claim, so always check the current commencement position.
Evidence checklist
- Documentary — lease, deeds of variation, demands, s.21B summary of rights, accounts, invoices, tender returns, minutes.
- Witness — statements from directors / residents / managing agent; signed with the standard statement of truth.
- Expert — surveyor / valuer / accountant where the tribunal has permitted expert evidence (rare in low-value cases; standard in enfranchisement and major works).
- Photographic — dated, geo-tagged where possible; do not rely on stock imagery.
Key caselaw
- Daejan Investments Ltd v Benson [2013] UKSC 14
- Arnold v Britton [2015] UKSC 36
- Aviva Investors v Williams [2023] UKSC 6
- Waaler v LB Hounslow [2017] EWCA Civ 45
- Gilje v Charlgrove Securities [2001] EWCA Civ 1777
Common mistakes
- Filing without a Scott Schedule — the tribunal cannot decide item-by-item without one.
- Overloading the bundle — every page must earn its place; a 2,000-page bundle loses more than it wins.
- Missing the s.20C and para 5A applications at issue — asking at the door of the hearing rarely succeeds.
- Confusing service charge with administration charge (variable admin charges have their own regime under Schedule 11 CLRA 2002).
- Assuming payment closes the door — s.27A(2) preserves the right to challenge historic charges.

Frequently asked questions
Do I need a solicitor for how to serve a section 42 notice — lease extension?＋
No. The First-tier Tribunal (Property Chamber) is designed to be accessible to litigants in person, and lay representatives are permitted under the Legal Services Act 2007. That said, high-value enfranchisement, complex Building Safety Act claims and cases with novel points of law are usually run with counsel.
What does the FTT actually cost?＋
Fee bands are £100 issue + £200 hearing (band A) or £20 + £150 (band B), with full remission on Help with Fees. Because the tribunal is a no-costs jurisdiction, most litigants' biggest exposure is the landlord's ability to add its litigation costs to the service charge — which is why s.20C and para 5A applications matter.
How long does a case take?＋
From issue to decision, expect 5–8 months for a standard track case, 2–4 months on the paper track, and 9–18 months for enfranchisement or building-safety claims that require expert evidence and site inspections.
Can I recover my own costs if I win?＋
Rarely. Rule 13 of the 2013 Rules allows a costs order only where the other side has acted unreasonably in bringing, defending or conducting the proceedings — a high bar. The real prize for leaseholders is not paying the landlord's costs via a s.20C order.
Does paying under protest waive my right to challenge?＋
No. Section 27A(2) of the Landlord & Tenant Act 1985 expressly preserves the right to challenge charges that have already been paid, provided the payment was not made under a binding compromise or admission agreement.
