How much is council tax in Lewisham?

Band D for 2026‑27: £2,237 a year

Every other band is a fixed share of Band D, set in law. Band A is two thirds of it; band H is twice it.

Band D is the average across the area, including the county council, police, fire and combined authority charges, and parish or town council charges, so a home's own bill can be a little different. Bands other than D are worked out by us from Band D and rounded to the pound. A home's bill also takes off any discount, such as 25% for one adult living alone.
