Compare Band I across UK councils

The table above shows Band I charges across our sample UK councils, each using its own nation's ratio. Use our side-by-side comparison page for the full billing-authority list with sortable Band D charges.

How we calculate Band I charges

Every billing authority sets its own annual Band D rate; Band I is then a fixed statutory proportion of that rate (21/9), so the charge tracks the local Band D rather than a single national figure. That produces the 1.3-times spread between the dearest (Merthyr Tydfil) and cheapest (Cardiff) shown above. Each council's charge above uses its own nation's statutory ratio under the Local Government Finance Act 1992, see our methodology page for the full per-country schedule.

UK tools, directories and calculator

Charges use each nation's statutory band ratio applied to the council-set Band D; your bill may include parish or special-expense precepts.
