Informal vs Formal Council Tax Band Review: Which Route to Take

There are two ways to ask the VOA to look at your council tax band, and they give you very different rights. An informal review is a request; a formal proposal is a statutory mechanism with deadlines, a guaranteed decision, and a route to the Valuation Tribunal if the answer is no. Choosing the wrong one can leave you with no appeal route at all.

The Informal Review

An informal review is exactly what it sounds like — you contact the VOA and ask them to check whether your band is correct. There is no statutory form, no filing deadline that applies to you, and no fee. You can do it online through the GOV.UK "Check and challenge your council tax band" service or by letter.

The VOA looks at the information on file, possibly cross-checks a few comparators, and sends you a response. If the Listing Officer agrees the band is wrong, they alter the Valuation List. If they disagree, they tell you so — and that is where it ends. An informal review does not create a right of appeal to the Valuation Tribunal for England. The VOA's refusal to act on an informal basis is discretionary, and there is no statutory route to challenge a discretionary refusal.

Informal reviews are available to anyone at any time, regardless of how long you have lived in the property. That makes them the only option for long-term residents who are outside the six-month statutory window and who cannot point to a qualifying material change.

The Formal Statutory Proposal

A formal proposal under Regulation 4 of the Council Tax (Alteration of Lists and Appeals) (England) Regulations 2009 is a different mechanism entirely. It triggers a structured process with statutory deadlines:

1. You submit the proposal, stating your name, address, current band, the band you believe is correct, and the evidence supporting the change.
2. The VOA must acknowledge receipt within 14 days.
3. The Listing Officer has four months to investigate and issue a formal Decision Notice — accepting, partially accepting, or refusing the alteration.
4. If the VOA refuses, you have three months from service of the Decision Notice to appeal to the Valuation Tribunal for England.
5. If the VOA fails to issue a decision within four months, you can appeal directly to the VTE.

The critical difference is the appeal right. A formal proposal that is refused opens the door to the VTE, an independent tribunal that can order the VOA to change your band. An informal review that goes nowhere gives you no such right.

Who Can File a Formal Proposal

Not everyone qualifies. Under Regulation 4(5)(a), a new taxpayer — someone who has just become liable for council tax on the property (typically through buying it or starting a tenancy) — has a strict six-month window from the date they became the taxpayer. Miss this deadline and the statutory proposal route closes.

Outside the six-month window, a formal proposal is available only on specific grounds:

• A material reduction in the property's value (partial demolition, adverse physical changes in the locality)
• A material increase combined with a relevant transaction (sale of the property after improvements)
• The property has been split or merged (disaggregation)
• A billing authority believes the band is wrong and submits its own proposal

If none of these apply, you are limited to the informal review route.

Which Route Should You Take?

The decision tree is straightforward:

Within six months of becoming the taxpayer? File a formal statutory proposal. You have the right to do so and it gives you a guaranteed decision with a tribunal appeal route. Even if your evidence is not ironclad, a formal proposal preserves your options.

Outside six months, with a qualifying material change? File a formal proposal citing the specific ground.

Outside six months, no qualifying change? Request an informal review. Prepare the strongest comparator evidence you can — identical properties on the same street in a lower band, supported by 1991-era sale data or Property Attribute Data. The better your evidence, the more likely the Listing Officer is to exercise their discretionary power to correct the list.

One important caution for either route: the VOA is legally required to keep the Valuation List accurate. If their investigation reveals your property is underbanded, the band goes up, not down. This risk exists whether you file informally or formally.

Building Your Case Either Way

Whether you go informal or formal, the evidence that matters is the same: direct comparators in a lower band, 1991-era valuations, and physical specifications showing your property matches the comparator profile. The council tax band challenge guide walks through the evidence-gathering process step by step, including how to request Property Attribute Data from the VOA and where to find historical sale prices.

The choice of route determines your legal rights if the VOA says no. The evidence you assemble determines whether the VOA — or a tribunal panel — says yes.
