Weighting every band by how many homes sit in it, the typical council tax bill in RG18 is about £2,735 a year (£228 a month) at West Berkshire’s 2026/27 charges — Band D itself is £2,505, up 5.1% on 2025/26. Bands were set from 1 April 1991 values in England and Wales (2003 values in Wales) and only change on a revaluation or a successful challenge, so the mix below shifts slowly.
Across England and Wales 22% of homes are Band C, so RG18 is heavier than average in that band; 9.3% of homes here are Band A or B (43% nationally) and 36% are Band E or above (20% nationally).
These are the Valuation Office Agency’s counts for the statistical areas that make up RG18, not a look-up of your address — for the exact band of one property use the VOA band search. Charges include the adult social care precept and police, fire and parish precepts where West Berkshire reports them in its Band D figure; single-person and other discounts come off afterwards.

How old the homes are
| Built | Homes | RG18 | England & Wales |

17% of homes in RG18 were built before 1939, against 35% across England and Wales. Older stock usually means lower EPC ratings and higher heating bills — relevant because privately rented homes need EPC C by 1 October 2030, and West Berkshire’s EPC page shows how far the local stock is from that line.
If you let a home in RG18
- Empty between tenants: the landlord is liable for council tax during a void, and West Berkshire sets its own empty-home discount or premium — see West Berkshire council tax 2026/27 and council tax in void periods as a deductible expense.
- Second homes and long-term empties: a 100% premium can apply from April 2025 — the premium tracker lists each council’s decision.
- HMOs: since 1 December 2023 a licensed HMO is banded as one dwelling in England, with the landlord liable — check licensing rules by council.
- Buying to let here: run the second-home stamp duty and buy-to-let stress test at the RG18 median, then the rental income tax calculator.
