Statute limits the amount that can be recovered from tenants of dwellings by way either of service charges (which include insurance rent) or administration charges. In both cases, the landlord can recover no more than is ‘reasonable’, notwithstanding any contrary provision in the lease. The landlord’s ability to forfeit the lease for non-payment is also subject to statutory control, but this is outside the scope of this Practice Note (see Practice Note: Statutory limitations on the landlord’s right to forfeit a long residential lease). Sections 18–25 of the Landlord and Tenant Act 1985 (LTA 1985) cover limitations to, and the reasonableness of, service charges, requests for summary of relevant costs, effects of change of landlord and assignment, as well as providing for an offence of failure to comply. The provisions apply to all dwellings and cover all residential leases, except where LTA 1985, s 26 applies. Section 26 provides for an exception in the case of tenants of certain public authorities.
