Council tax bands in England were decided back in 1991, based on property values from thirty-three years ago. Yes, you read that right: your 2026 tax is pinned to what your house was worth in the era of grunge music and Terminator 2. In London, this system is completely cracked. A house on a square in Kensington that was valued at £320,000 in 1991—now worth maybe £10 million—sits in the same Band H as a smaller, but still swanky, townhouse in Hampstead.
The result? Boroughs like Kensington and Chelsea, Westminster, and Camden are the kings of the council tax mountain. In Kensington and Chelsea, the average Band H property pays roughly £1,851 for the year. But wait—didn’t I just mention £11,412? That’s because some boroughs slap on an extra “precept” for the Greater London Authority, police, and fire services. In that same borough, a Band H home with the full precept can hit £2,747—but the richest ones, with special parish charges? That’s where you get the £11k.

Here’s the kicker: your bill depends as much on where you live as on how many bedrooms you have. Move from Barnet to Richmond upon Thames, and your Band H bill could jump by hundreds of pounds. (Seriously—I checked. It’s like a video game where your salary doesn’t increase, but the difficulty level does.) In Barking and Dagenham, a Band H property—if one even exists there—would cost you around £2,400. In Westminster? You’re looking at £3,200 on average. That’s the price of a decent annual commute.
Where is the most expensive and cheapest council tax in England
And let’s not forget the irony: the boroughs with the highest property prices—and thus the richest residents—often charge the most council tax. Kensington and Chelsea, Westminster, and the City of London are at the top. So yes, the people who can afford not to worry about the cost are the ones paying the biggest bill. (Cue the world’s smallest violin, but tune it to a sorry note.)
