What makes a service charge demand valid?

To be legally effective, a service charge demand must show the landlord's name and address, give an address for serving notices, come with the prescribed Section 21B summary of tenants' rights, and follow the machinery in the lease. If those are missing, the sum is generally not payable until the defect is fixed.

A service charge demand is not automatically enforceable just because it lands on your doormat. The law sets out several requirements a landlord must meet, and if any is missing the demand can be defective — meaning the money is not yet payable. Knowing these requirements is one of the most practical things a leaseholder can learn, because a defective demand can be withheld without you being in breach.

The four things a valid demand needs

  • The landlord's name and address — required by Section 47 of the Landlord and Tenant Act 1987. Every written demand for rent or service charge must state the name and address of the landlord.
  • An address for serving notices — under Section 48 of the Landlord and Tenant Act 1987, the landlord must give the tenant an address in England or Wales at which notices (including proceedings) can be served on the landlord. Until that address is supplied, the service charge is treated as not being due.
  • The Section 21B summary of rights and obligations — a demand must be accompanied by the prescribed summary of tenants' rights and obligations under Section 21B of the Landlord and Tenant Act 1985. Without it, the tenant may withhold the service charge until the summary is provided.
  • Compliance with the lease — the demand must also follow the "machinery" in your lease: demanded by the right party, in the right form, at the right time and in the way the lease specifies. Getting the contractual mechanics wrong can be just as fatal as missing a statutory requirement.
The practical effect: if these requirements are missing, the sum is generally not payable until the defect is put right. Importantly, any ground rent or service charge you withhold for that reason is not treated as being "in arrears" — so you are not in breach, and the landlord cannot rely on the non-payment as if you had simply refused to pay a valid bill.

Don't forget the 18-month time limit

Validity is not only about what the demand contains — it is also about when it arrives. Under Section 20B of the Landlord and Tenant Act 1985, if a leaseholder is not demanded a cost, or notified that the cost has been incurred, within 18 months of it being incurred, the landlord may be unable to recover it at all. A demand can therefore be validly served but still time-barred as to some of the costs it covers.

Validity is separate from reasonableness

A demand can tick every validity box and still be challengeable on amount. Even a perfectly served demand only recovers costs that are reasonably incurred under Section 19 of the Landlord and Tenant Act 1985. Validity gets you to the starting line; reasonableness decides whether the figure itself should stand. Our guide on how to read your service charge demand walks through both checks in order.

How this shows up in your service charges

Defective demands are more common than most leaseholders realise — a missing Section 48 address or absent Section 21B summary can make a whole demand unenforceable. Our free AI audit reads your service charge demand, accounts and lease, flags the validity points, and shows you, line by line, how much could be challengeable under the Landlord and Tenant Act 1985.
