The agent hasn't said which band this home is in; you can look it up on GOV.UK. In Buckinghamshire, 2026/27 bills run from £1,684 a year in band A to £5,053 in band H.

Figures from MHCLG (Open Government Licence v3): the average bill for each band across Buckinghamshire, 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.
