Proposal vs informal review: which Council Tax challenge route applies to you?
The VOA offers two routes for challenging a band. Picking the wrong one wastes months. Here's the rule.
A formal proposal and an informal band review are the two routes for challenging your Council Tax band — and which one you're entitled to use comes down to a single rule about timing.
The short answer
| Your situation | Route | VOA must review? |
|---|---|---|
| Less than 6 months at the property | Formal proposal | Yes, by law |
| Within 6 months of a band change | Formal proposal | Yes, by law |
| Anything else | Informal band review | Only with strong evidence |
If you're eligible for a formal proposal, use that route — it's stronger.
Why the difference matters
A formal proposal triggers a legal obligation. The VOA must consider your case and respond with a formal decision, which you can then appeal to the Valuation Tribunal. The whole process is on the record and has statutory deadlines.
An informal band review is a discretionary process. The VOA will look at your case if you provide convincing evidence, but they're not legally required to act on it. If they decline to review, you have limited recourse — the Valuation Tribunal generally only hears formal proposals.
In practice, both routes often succeed with similar evidence. But if you have the right to a formal proposal, take it. It gives you more leverage and a clearer escalation path.
How to know if you can use the formal proposal route
You can make a formal proposal if any of these apply:
- You moved into the property within the last 6 months (you are the new Council Tax payer).
- The VOA changed your band within the last 6 months.
- The VOA refused a previous proposal you made.
- The property's circumstances have materially changed (e.g. demolition of part of it).
If none of these apply, you're limited to the informal review route.
What the proposal needs to include
For a formal proposal, the VOA must accept your submission if it includes:
- Your name and address.
- The address of the property you're challenging.
- A clear statement that you propose the band be altered (and to what band).
- The grounds for the proposal — typically the comparables evidence.
The VO 7455 form covers all four. Our pack pre-fills it.
What the informal review needs
An informal review has a higher bar because the VOA is choosing whether to engage. Practically:
- Evidence is mandatory — they won't entertain "I think it's wrong" without comparables.
- The neighbours method is the most persuasive single line of argument.
- 1991 sale-price evidence strengthens the case but isn't always required.
The same VO 7455 form works for an informal review; you just tick the relevant box.
What if you mis-route?
If you submit a formal proposal when you're not eligible, the VOA will usually treat it as an informal review request rather than reject it outright. So mis-routing on this is rarely fatal — but you lose the legal protections of the proposal route.
The pack auto-selects the right route based on what you tell us about your situation, so this typically isn't something you have to think about. If you want to verify, the cover letter explicitly states the route at the top.
