Increased Council tax banding 40 years later

Posting on here for traffic.

We bought a house in October 2025 that had had an extension done in the 1980s.

For 40 years the house has been on band X, and we have continued to pay the same band for nearly 6 months. Council have written to say they have re-evaluated the property's value in 1994 and deemed it was worth more than they thought and therefore because of the sale we are now being moved up a higher tax band.

This feels utterly farcical and money grabbing from the council.

We had the same 2 years ago

I moved into a new house and now pay band D. My best friends house is bigger than mine but because it hasn’t been rebanded it’s a band A.
I think there needs to be a national shake up rather than just pockets like you’re experiencing. It’s not fair on those paying correctly by modern standards.

Yeah and the extension work with associate paperwork was all already completed before this date of 1991 (sorry I'd be previously posting 1994).

There has to be a statue of limitations. I mean there are time limits for varying crimes and infringements but council tax is forever!

Because you are now being charged the correct band. You were previously paying less than others who have the same type of house and now you are paying the same as other people who have the same type of house. That's perfectly normal and fair. I can't see a single wrong with this.

So to continue with this analogy - let's say you had a job and you get a promotion with increased pay but do not pay any tax on the increase for 40 years. You then retire but don't tell your new hire about the promotion and 6 months in the newbie has to pay increased tax and all of this according to most people is fair, ethical and above board.

This is exactly what you are saying.

OP you can appeal the rebanding.

In my circumstances I purchased a house at band F, did my research and after much persistence it was rebanded as an E.

Don’t sit back and be passive about this. I had to fight the valuation office but with a surveyor I instructed the VO eventually backed down!

Thank you for this genuinely valuable response.

The timelines on this don't make sense. If the extension was done 40 years ago in 1986, then it would have been assessed at 1991 for council tax including the extension. So it shouldn't have needed to be reassessed.

JehovasFitness · 28/03/2026 07:43

I’d be annoyed at my conveyancer/myself for not doing the due diligence.

It has just taken me ninety seconds to see which houses on my street have an improvement marker.

At some point they’ll have to change the council tax system anyway because it isn’t an equitable system and most of us don’t pay enough, considering huge swathes of the population have chosen to make the council responsible for their care needs later in life.

ThirdStorm · 28/03/2026 07:32

Could you put in a challenge based on neighbouring properties of similar size being the original band? Assuming they are. Use Martin Lewis guide, it’s brilliant.

The Council does not band houses - the Valuation Office Agency does. The Council then has to bill based on what’s in the valuation list.
The VOA can revalue when a property changes hands.
You can make an appeal to have your banding reduced but this can take ages and be aware that they can decide to increase the band further as part of the appeal.

Cantthinkofanewusernameffs · 28/03/2026 01:29

We extended our house and knew it would be re banded when we sold. When we did sell, I informed viewers that it was likely to go up.

The house we bought had had a small extension. A few months after we moved in, a representative from the council called round to assess the property. Fortunately the extension didn't increase the square footage of the house by enough to affect the band.

sesquipedalian · 28/03/2026 01:19

I understood that when you buy a property, they can shift it up one band, if changes have been made by the vendors since they bought it. It happened when I bought our house. You can challenge it if you feel you have a strong case, but if the previous owners have improved or extended their house while living there, the council tax wouldn’t have changed until the house was sold, no matter how long ago it was done.

Tiptopflipflop · 28/03/2026 01:03

It is common practice to reband after a sale, but given that the extension was already there when the property was originally valued from what you're saying, I would imagine you would have reasonable ground to challenge it. Is the banding out of step with other equivalent properties locally?

Money Saving Expert has good information on challenging banding more generally which would be a good place to start.

It is government legislation and must be adhered to by the Council. They don't make the rules.

Unfair definitely but I guess many taxes aren't exactly fair.

Abra1t · 28/03/2026 00:54

We have paid more than our neighbours in similar-sized houses for decades. If we ask to be reassessed, the risk is they are moved to our band and we stay the same. We haven’t done it but it does annoy me that they pay less.

MistyMountainTop · 28/03/2026 00:44

You get advised when you do an extension that the council tax band may be re-evaluated/increase at the point of sale. I thought this was pretty well known but obviously not! That's one of the reasons that people extend rather than moving.

I do think that your conveyancer should have picked it up as I assume you got the signed off documents from building control

frogspawn15 · 28/03/2026 00:41

This just happened to us and we were equally shocked. We bought our house 15 months ago and the extension was completed over 20 years ago. The registered owner change at Land Registry seems to have been the prompt.

JemimaTiggywinkles · 28/03/2026 00:36

Council tax is based on the idea that people with bigger / more expensive housing should pay more. Just like income tax. If your house is extended it is bigger (and presumably more expensive) than a neighbour with no extension. It doesn’t seem unreasonable to be in a higher band. Seems odd that the review is at point of sale, but I’d bet that the government don’t want to discourage people from improving their own homes for quality of life (rather than resale value) reasons.

I only looked into it as I was helping family out with a question as to why one family member who lives in a tiny two bed bungalow is paying the same band as the other family member who lives in a 5 bed 3 bath detached. I found out it was because the family member in the large house had extended their house extensively 40 years ago and then never moved.
I think they should put something on the sale information really. Rather than just state the current band.

It is mindboggling that the people whose chosen to build the extension and the enjoyed it for FORTY Years didn't have to pay this higher council, but the people that bought it completely ignorantly and weren't even born at the time of the extension now are slapped with this extra bill.
And apparently that is the way of the world.

I would have thought that when the solicitor carried out the searches, and found out that the property had been altered by the current owner/from the original deeds, then they would check to see if there is an improvement marker. Maybe not, but it seems a natural route for those in the know.

Banding reviews aren't carried out when improvements happen as houses change so much it would trigger 100s and 100s of thousands of requests a year, which is unmanageable, but I agree a buyer generally wouldn't have a clue and it should be spoken about in the sale process.

Thank you that is helpful to know that this is how it is done..
My disbelief was more at the why is it this way angle.

thats awful! just another money grab! what band will you be now?

The2ndMrsMaximDeWinter · 28/03/2026 00:22

It's normal in the sense that they can only review the banding at point of sale, they couldn't have done it earlier as it simply isn't allowed.

The Value Office Agency (Govt department who assess banding) and Council haven't done anything wrong, but I am surprised it wasn't picked up by the conveyancer.

If you go on the VOA website and look at any house it will show if there's an improvement marker on. We have had a large extension and we have such a marker so if we sell it will be reviewed. But I know this due to a previous line of work, I don't imagine it's common knowledge and would have assumed your solicitor would pick it up.

No am afraid no one else has picked it up or remarked on it.
Nasty surprise when I opened that blue letterhead paper simply stating they are going to put it up based on values in 1994.
