Council Tax bands in Cardiff
A Band D household in Cardiff pays £2,013 in 2026/27. Every other band is a fixed proportion of that figure — the proportions are set in law, so once you know the Band D amount you know what every band costs. The table below is that calculation, alongside how many homes in Cardiff actually sit in each band.
What each band costs in Cardiff
Figures include the precepts charged alongside the council’s own share — police, fire and, where they apply, county and parish precepts. This is the amount a household is billed, not the council’s own portion of it. Charges are rounded to the nearest pound; your actual bill states pence.
| Band | Value at 1 April 2003 | 2026/27 charge | Homes | Share |
|---|---|---|---|---|
| A | up to £44,000 | £1,342 | 5,320 | 3.2% |
| B | £44,001–£65,000 | £1,566 | 20,420 | 12.2% |
| C | £65,001–£91,000 | £1,789 | 34,920 | 20.9% |
| Dmost common | £91,001–£123,000 | £2,013 | 37,370 | 22.4% |
| E | £123,001–£162,000 | £2,461 | 31,540 | 18.9% |

| I | over £424,000 | £4,697 | 1,480 | 0.9% |
What the numbers say about Cardiff
Cardiff has 166,740 domestic properties on the valuation list. 36.4% of them are in bands A to C, and 58.8% are at Band D or below. The most common band is Band D.
For a typical Cardiff home, moving from Band D to Band C would cut the annual bill by about £224. A successful challenge is also normally backdated to when you moved in, so the one-off refund is often several times the annual figure.
Cardiff has the most band-heavy profile of the Welsh authorities in this pilot, with only about a third of homes in bands A–C and more than a fifth in band F or above. Like all of Wales it is banded on 2003 values. Because Cardiff's suburbs expanded in distinct waves, two houses of similar size can sit in different bands purely because of when they were built and what the surrounding street looked like at the 2003 valuation.
Does that mean your band is wrong?
Not on its own. The single most common mistake is reading a table like the one above and concluding that because most homes nearby are in a lower band, yours must be too. Band is a judgement about your specific property at 1 April 2003 — its size, type and age — so the only comparisons that count are with properties genuinely like yours. A large detached house surrounded by flats is usually banded correctly, however lopsided the street looks.
Be aware too that a review can move a band up as well as down, and it can affect neighbouring properties. That is why our free check scores the strength of the evidence before anything else, and tells you plainly when a challenge is not worth pursuing.
Where these figures come from
Band D charges are Welsh Government published figures for 2026/27, including all precepts. The per-band charges are derived from that Band D amount using the statutory ratios, which is exactly how a council calculates them. Property counts are the Valuation Office Agency’s Council Tax stock of properties data as at 31 March 2025. All three are Open Government Licence.
Charges change each April and stock counts are published annually, so treat the counts as the most recent official position rather than a live figure.
