Welsh Council Areas: Highest and Lowest Council Tax in 2026/27
Wales's 22 principal councils each set their own Band D council tax rate, and Wales as a whole has tended to run above the England average. Here's how the system works for 2026/27.
Twenty-Two Councils, One Revalued Band System
Wales's 22 principal councils — from Cardiff and Swansea to Powys and Gwynedd — each set their own Band D council tax rate annually. Unlike England, Wales carried out a full council tax revaluation in 2003, which produced a genuinely different band structure from the rest of Great Britain.
Wales's Extra Band and 2003 Revaluation
| Feature | England/Scotland | Wales |
|---|---|---|
| Number of bands | 8 (A-H) | 9 (A-I) |
| Valuation date | 1 April 1991 | 1 April 2003 |
| Revaluation since original | None (England); none (Scotland) | Completed in 2003 |
Wales's 2003 revaluation updated property values to reflect price changes since 1991, and added a new top Band I for the highest-value properties, which didn't exist under the original A-H structure. This means Welsh council tax bands reflect more recent property values than English or Scottish bands.
Why Wales Runs Above the England Average
On average, Welsh council tax bills have tended to run above the England average for a comparable band, reflecting differences in the local government funding formula and each council's own spending decisions. This is a general pattern rather than a universal rule — some individual Welsh councils sit closer to English averages, and rankings shift with each year's budget cycle.

Wales gives councils the power to apply a council tax premium of up to 300% on qualifying second homes and long-term empty properties — among the highest premium ceilings available anywhere in the UK. Several Welsh councils, particularly in areas with significant holiday-home pressure such as parts of Gwynedd and Pembrokeshire, have applied substantial premiums as a deliberate tool to address local housing availability for permanent residents.
Discounts That Apply Everywhere in Wales
Regardless of which council area you're in, the standard Wales-wide discounts apply: a 25% single-person discount, certain student household exemptions, and means-tested Council Tax Reduction for those on a low income.
The Bottom Line
There's no fixed "highest" or "lowest" Welsh council for council tax that holds true year after year — all 22 councils reset their Band D rate annually. What is consistent is that Wales's overall average tends to run above England's, its band structure is based on more recent 2003 valuations with an extra top band, and several Welsh areas apply among the UK's highest second-home premiums.
