Council tax bands in NN29

Weighting every band by how many homes sit in it, the typical council tax bill in NN29 is about £2,194 a year (£183 a month) at North Northamptonshire’s 2026/27 charges — Band D itself is £2,424, up 5.3% 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 20% of homes are Band B, so NN29 is heavier than average in that band; 49% of homes here are Band A or B (43% nationally) and 16% are Band E or above (20% nationally).
These are the Valuation Office Agency’s counts for the statistical areas that make up NN29, 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 North Northamptonshire reports them in its Band D figure; single-person and other discounts come off afterwards.

28% of homes in NN29 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 North Northamptonshire’s EPC page shows how far the local stock is from that line.
If you let a home in NN29
