Carmarthenshire Council Tax 2026

How to read this stock pattern

Carmarthenshire's largest property group sits in the lower half of the valuation ladder rather than at the Band D reference used in national tables. Its modal Band B charge is seven-ninths of the Band D rate, and 58.5% of the published stock lies below D. The headline alone does not show how often each band occurs. The stock-weighted amount applies the full distribution for an area-level comparison, while remaining an average rather than a household quotation.

Carmarthenshire has a broad valuation-band profile: the largest 3 groups are needed before the cumulative share passes half of the stock. No single band dominates the local picture, which makes a one-band headline especially incomplete. The weighted result is useful for comparing this authority with peers, but the spread across 9 published bands matters just as much. A broad mix also means the area-level mean is less representative of any one household than it is in a concentrated council.

Carmarthenshire occupies the middle half of the Wales stock-weighted distribution, above its £2,258.00 median. The regional result gives more context than a UK-wide rank without turning the difference into a superlative. It also shows that the council's band mix, not only its published Band D rate, determines where it sits among nearby authorities. The remaining distance from the median is an area-level comparison rather than a household saving or premium.

Closest housing-stock shape: Gwynedd

Gwynedd is the closest full-distribution match for Carmarthenshire. The profiles are close rather than identical: 5.6% of dwellings would need to shift between valuation bands for their published shares to align. The comparison therefore tests the whole ladder, not just the largest band.

Four largest band differences

• The largest separation sits at lower Band A, where Gwynedd holds 15.0% of its stock and Carmarthenshire holds 10.4%. The peer is more bottom-weighted at this rung of the valuation list.
• A smaller distinction is lower on the ladder at Band B: Carmarthenshire has 27.1% of dwellings there, against 25.3% in Gwynedd. That extra lower-band weight pulls its stock profile away from the peer.
• A smaller distinction appears in the upper part of the ladder at Band E. Carmarthenshire places 14.9% of dwellings there versus 13.3% for Gwynedd, giving this profile the heavier upper-band tail at that point.
• A smaller distinction appears in the upper part of the ladder at Band F. Carmarthenshire places 7.4% of dwellings there versus 6.5% for Gwynedd, giving this profile the heavier upper-band tail at that point.
