The agent hasn't said which band this home is in; you can look it up on GOV.UK. In Westminster, 2026/27 bills run from £700 a year in band A to £2,099 in band H.
Figures from MHCLG (Open Government Licence v3): the average bill for each band across Westminster, including the typical parish precept, so a parish's own bill can differ a little. Discounts lower the bill, such as 25% off for an adult living alone.
