One of the most common queries to the LEASE advisory service (government leasehold advice)

Your service charge demand
may not be legally enforceable.

Most leaseholders pay demands without checking if they're valid. Many aren't. Here's exactly how to check yours . step by step . using your lease, the demand letter, and free tools.

What the law requires

A valid service charge demand must satisfy all of these.

Every one of these is a statutory requirement. Miss one and the demand may be unenforceable until corrected.

⚠ Often missing

Section 47/48 LTA 1985 . Landlord name & address

s.47/48 LTA 1985

The demand must include the landlord's name and an address in England or Wales where notices can be served. If missing, the leaseholder is not obligated to pay until it's provided.

Missing → legally withhold payment

⚠ Often missing

Section 21B . Summary of Rights & Obligations

s.21B LTA 1985

A prescribed Summary of Tenant's Rights must accompany every demand. It's a statutory requirement . not optional. Omitting it makes the demand unenforceable until served.

Missing → demand unenforceable

⚠ Check required

Section 19 . Reasonableness

s.19 LTA 1985

Charges must be reasonably incurred and works/services must be of a reasonable standard. Leaseholders can challenge unreasonable charges at the First-tier Tribunal.

Unreasonable → FTT challenge available

⚠ Check the date

Section 20B . The 18-month rule

s.20B LTA 1985

A landlord cannot recover costs incurred more than 18 months before the demand unless the leaseholder was notified within that period. Back charges older than 18 months may be unenforceable.

Older than 18 months → may not be recoverable

⚠ If works included

Section 20 . Major Works Consultation

s.20 LTA 1985

If major works are included and the cost to any leaseholder exceeds £250, the landlord must have carried out a formal Section 20 consultation first. Skip this and recoverable costs may be capped at £250.

No consultation → costs capped at £250/leaseholder

✓ Check lease date

Ground rent compliance

Ground Rent Act 2022

Any ground rent demand for a regulated lease (granted after 30 June 2022) must be a peppercorn. Any higher demand is unenforceable and the landlord commits a criminal offence.

Higher than peppercorn → criminal offence by landlord

How to check yours . step by step

6 checks. Do them in order. You need your demand letter and your lease.

Each check tells you exactly what to look for, where to find it, and what it means if it's missing. Where your lease is relevant, LEASE-iQ can read it for you.

1

Does the demand include the landlord's name and address?

s.47/48 Landlord and Tenant Act 1985

What to do: Look at your demand letter. It must state the landlord's full legal name and an address in England or Wales where notices can be served. A PO Box or overseas address does not count.

If it's missing: You are not legally obligated to pay until this information is provided. This is one of the most commonly missing items . especially in self-managed blocks where the freeholder company address isn't on the demand.

⚠ Missing = you can legally withhold payment until corrected
2

Was a Summary of Rights and Obligations served with the demand?

s.21B Landlord and Tenant Act 1985

What to do: Check whether a separate document titled "Summary of Tenant's Rights and Obligations" was included with your demand. It's a prescribed statutory form . not something the landlord writes themselves. It must accompany every demand.

If it's missing: The demand is unenforceable until it is served. Many managing agents forget this or include an outdated version.

⚠ Missing = demand is unenforceable until served
3

Does the demand match what your lease says about payment?

Lease compliance check

What to do: Your lease specifies how the service charge should be calculated . the apportionment percentage, payment schedule (quarterly, half-yearly, annually), and what costs are recoverable. The demand must follow these terms.

This is where most people get stuck . the relevant clauses are buried in dense legal language. Upload your lease to LEASE-iQ and ask it to find the service charge clauses, the payment schedule, and the apportionment method.

LEASE-iQ can help here

Upload your lease and ask: "What does my lease say about service charge payment . the schedule, the percentage I pay, and what costs the landlord can recover?"

4

Are any of the costs older than 18 months?

s.20B Landlord and Tenant Act 1985

What to do: Look at the line items on the demand. Were any of these costs incurred more than 18 months ago? Check invoices, receipts, or accounts to see when the money was actually spent.

If yes: Unless you were notified within 18 months that the costs had been incurred, the landlord may not be able to recover them. This is a strict time limit.

Costs older than 18 months without prior notice → may not be recoverable
5

Does the demand include major works? Was Section 20 consultation done?

s.20 Landlord and Tenant Act 1985

What to do: If any works or long-term contract costs on the demand exceed £250 per leaseholder, the landlord must have carried out a formal Section 20 consultation before the work was done. This is a two-stage process with specific notice requirements.

What to check: Did you receive a "Notice of Intention" before the work started? Were you given 30 days to respond? Were alternative estimates obtained? If not, recoverable costs may be capped at £250 per leaseholder.

No consultation → costs capped at £250 per leaseholder
6

Are the charges reasonable?

s.19 Landlord and Tenant Act 1985

What to do: Even if the demand is procedurally correct, the amounts must be reasonable. Compare individual line items to what similar buildings pay. Are the managing agent's fees in line with market rates? Is the insurance premium competitive? Are cleaning or gardening costs proportionate?

If you think it's too high: You can apply to the First-tier Tribunal (Property Chamber) to challenge the reasonableness. Fees are typically under £300 and you don't need a solicitor.

Check what your lease allows

Upload your lease to LEASE-iQ and ask: "What costs can the landlord recover through the service charge under this lease? Are there any caps or exclusions?"

What to do with your results

Found a problem? Here's what happens next.

Steps 1 or 2 failed . demand is unenforceable

Write to your landlord or managing agent stating that the demand does not comply with s.47/48 or s.21B of the Landlord and Tenant Act 1985, and that you are withholding payment until the defect is corrected. Keep it factual. They can re-serve a corrected demand . but the clock resets.

Steps 3 to 6 raised concerns

You may have grounds to challenge at the First-tier Tribunal, or to negotiate directly. Start by requesting a summary of costs (your right under s.21 LTA 1985) and copies of all invoices. Call LEASE advisory service (free, government-funded) for advice on your specific situation.

Your lease holds the answers to most of these questions.
LEASE-iQ reads it in minutes.
