Service Charge Calculator

Leasehold service charges cover the cost of maintaining and managing communal areas of a building or estate. Common items include building insurance, cleaning, gardening, lift maintenance, communal lighting, management company fees and contributions to a sinking or reserve fund for major works. Charges vary widely from £500 to £5,000+ per year.

Under the Landlord and Tenant Act 1985, service charges must be reasonable, and landlords must consult leaseholders before carrying out major works costing more than £250 per leaseholder. Leaseholders have the right to challenge unreasonable charges at the First-tier Tribunal (Property Chamber).

This calculator estimates your annual service charge based on the building type, number of units, facilities and location. It also shows how contributions break down across categories and projects your costs over 5, 10 and 20 years including expected increases.
