The UK Leasehold Map.
How your lease, the statutes, and the Tribunals connect.

Seven journeys, mapped on one page. Service charge, Section 20 major works, demand validity, lease extension, forfeiture, take control, and director-side compliance. The lease sits in the middle of all of them.

How to use the map

Find your situation. Follow the line. Know what comes next.

Every leasehold dispute or compliance question lives on one of these seven lines. Each station is a legal step, statute, or document you might need to know about. Where lines meet (interchanges) is where the same rule applies in two places at once.

Service Charge Line (navy)

The annual cycle: budget set, demand issued (with the s.21B Summary of Rights), pay or challenge, year-end accounts, balancing charge, reserve fund. Where service charge disputes start. Service charge guide →

Section 20 Major Works Line (teal)

Stage 1 Notice of Intention. 30-day window for leaseholder nominations. Stage 2 Notice of Estimates. 30 days for observations. Stage 3 award. If the procedure slips, the freeholder loses recovery rights. Section 20 guide →

Demand Validity Line (amber)

s.47 LTA 1987 (landlord name + address), s.48 (UK service-of-notice address), s.21B Summary of Rights, s.166 CLRA prescribed form for ground rent. If a demand fails any of these, it isn't payable until reissued. Demand anatomy guide →

Lease Extension Line (green)

Years remaining. The 80-year marriage-value zone. s.42 notice. Counter-notice. Premium negotiation. Tribunal valuation. Completion adds 90 years at peppercorn ground rent. Lease extension guide →

Forfeiture Line (red)

The freeholder's nuclear option. Breach identified, waiver risk, s.146 notice, time to remedy, Court or FTT determination of breach, relief from forfeiture, mortgagee protection. Fast and dangerous if procedure is right. Easy to defend if it isn't. Demands and forfeiture guide →

Take Control Line (purple)

RTM qualifying conditions, RTM company formation, s.79 notice and counter-notice, FTT if disputed, right vests. Or s.13 collective enfranchisement. Or commonhold conversion (LRFA 2024). The leaseholder-led routes. Take control guide →

Compliance Line (grey, dashed) · director side

Higher-Risk Building registration, BSA leaseholder protection certificate, EWS1, Building Safety Levy, Fire Risk Assessment, EICR, Asbestos register, cladding remediation. Statutory duties on the freeholder/director side, often life-safety. Director compliance audit →

Interchanges (where the same rule is on two journeys)

  • The Lease itself · every line passes through here
  • Section 27A FTT · Service Charge + S20 + Demand Validity
  • Reasonableness, s.19 LTA 1985 · Service Charge + S20
  • Section 20B 18-month rule · Service Charge + Demand Validity
  • Section 146 · Forfeiture + Take Control + Compliance
  • Companies House · Take Control + Compliance
Why this map exists

Most leasehold disputes are not legal complexity disputes. They're asymmetric-knowledge disputes.

One side — the freeholder, the managing agent, their solicitor — has read the lease, knows the statutes, has the systems. The other side doesn't. The dispute exists in that gap. Solicitors then get hired to cross the gap, which adds cost, jargon, and delay to a problem that didn't need any of those things.

This map is the gap closed. Both parties holding the same map is roughly the conversation the lease was always supposed to enable. Print it. Pin it to the kitchen wall. Take it to the AGM. Quote the station name in the email. The conversation gets shorter and the dispute gets smaller.

Use this as a map, not as legal advice. Every station name is real, the section numbers are correct as of May 2026, and the journeys reflect current UK law for England and Wales. But each case turns on the wording of your lease, the dates on your documents, and the facts of your dispute. For a clause-cited written answer that applies the map to your situation, see LEASE-iQ (first question free) or Talk to us.

Take the map with you.
