CChallenge Council Tax Band
How it works · six steps

Six steps. About twenty minutes of your time — then the Valuation Office’s clock starts.

From a postcode in our box to a refund in your bank, drawn out so you know exactly what we do, what you do, and what the Valuation Office Agency does next. No buy button on this page — we’ll send you to the free check first.

  • Free to check
  • No card needed
  • 14-day refund
  • We refuse to recommend weak cases
Step one · free

Check your band, free.

Type your postcode and pick your address. We look up your home’s band, its energy certificate and its last recorded sale, and fill in what we find; you check it and correct anything that’s wrong. A minute or two. No card, no email, no account.

Type your postcode

Step two · the fork

An honest answer, and where the road forks.

We compare your home with similar homes nearby, like for like: the same type, a similar size and age. If they back a lower band, you see a Good case or Strong case and the option to buy your challenge, or a Fair case when they do but our house-price estimate points the other way, with that risk shown. If the case is weak, we say so and don’t sell you anything, and if the evidence suggests your band could go up instead, we tell you that too. That refusal is the whole reason this product is trustworthy.

One-off, through Stripe: no subscription, no success fee, and we never see your card.

Step three

Your challenge arrives.

A minute or two after you pay, one email with three things in it: your case report, the VO 7455 form part-filled, and the email to send the Valuation Office with the evidence written in. Prefer post? There’s a printable letter to download.

Your challenge arrives: your case report, the form and the email

Step four · optional

Make it yours.

We recommend it. Search more postcodes nearby, or one you know, and we put the strongest homes first. Choose which homes to cite, pick the letter’s tone and change any wording. We email you the updated version. No extra charge, and you can come back to it within 14 days.

Make it yours: more postcodes, your picks, your wording

Step five

Check, sign and send.

Check the details on the VO 7455 form and sign it. Then paste the email into a new message to [email protected], attach the form and send, and you keep a timestamped record. Prefer post? Send the printable letter with the form to the Valuation Office in Durham. We don’t send it for you: the challenge comes from you, with your signature.

Check and sign the form, then attach it and send

Step six

The decision, and your money back.

It takes longer than most people expect, so we keep you on track: a check-in after five days and a reminder to chase at five weeks. If your band is lowered, the Valuation Office tells your council, which recalculates your bill and repays or credits what you overpaid. It must repay it if you ask, and the letter to your council on your order page does the asking.

How long the Valuation Office can take, according to GOV.UK:
Informal band review
up to 12 months
Formal proposal
up to 4 months

We remind you to chase, and help you claim the refund

If they hold the band
Step six · branch

If the VOA refuses to lower the band.

It depends on the route. A formal proposal — open to you if you’ve paid Council Tax on the property for under six months — can be appealed to the independent Valuation Tribunal for free. An informal band review can’t be appealed, but you can ask for another one at any time if you find new evidence. Your order page has chase letters and the right follow-up for your route. Most of this won’t happen; we wrote it because some of it will.

Letters for later, on your order page
  • A
    Chase letter
    Checks the VOA has received your challenge.
  • B
    Status update request
    A polite nudge while the review is under way.
  • C
    The right next step for your route
    A tribunal appeal note for a proposal, or a new-evidence letter for a band review.

We don’t represent you in any of these — that’s deliberately the line. You fill in the blanks and send each letter yourself.

What this is NOT

Plain about what we don’t do.

Honesty is the product. If a competing service tells you otherwise on any of these, that’s your cue.

Not a subscription.

£39 is one-off. We never charge you again. No renewal, no auto-debit, no follow-up sales.

No success fee.

We don't take a slice of your backdated refund. The flat fee is everything you pay us, ever.

Not an agent acting for you.

We don't submit on your behalf: you check, sign and send. That's deliberate. The challenge is yours, the Valuation Office deals with you directly, and the signature stays where it belongs.

Not affiliated with HMRC or the VOA.

We use their published data; we are independent. If a service promises insider relationships at the VOA, walk away.
