⚠ Before you file: A challenge can RAISE your band — and your neighbors' bands. If your evidence is weak, do not file. The letter engine requires you to acknowledge this before drafting anything. Read the VOA’s verbatim warning →

Formal proposal or informal review? The timeline gap is 4 months vs. 12

The answer: if you qualify for a Formal PROPOSAL (a statutory right — the VOA is "required by law to accept all proposals"), the VOA must accept it and decide within decision can take up to 4 months (gov.uk, verified — not the "~2 months" figure that circulates). If you don't qualify, your only route is the Informal BAND REVIEW (available any time — needs strong evidence or the VOA will not review), which can take up to can take up to 12 months (gov.uk, verified) and succeeds only with strong comparable evidence.

Who qualifies for the formal proposal

You need one of the statutory grounds — see the full list on the SI 2009/2270 grounds page. In short: recent liability, a recent VOA band change, or a qualifying physical/use change to the property.

Everyone else: informal review

No formal ground applies if you've simply lived there a while with nothing physically changing. That doesn't mean no case — it means the informal route: submit your comparable-band evidence and ask the VOA to review. It can take up to 12 months (gov.uk, verified), and per the VOA's own guidance, weak evidence gets nowhere.

If the VOA says no either way

If the VOA says no: appeal to the Valuation Tribunal within 3 MONTHS of the decision in ENGLAND, 4 MONTHS in WALES (asymmetric — verified).
