Valuation Office Agency Wales (Now the Valuation Office): Informal Reviews, Formal Proposals and PAD Requests

What the Valuation Office Does (and Doesn't Do)

The Valuation Office is part of HMRC, not your local council. It took over the Valuation Office Agency's work on 1 April 2026. Its Listing Officers maintain the valuation lists for all 22 Welsh billing authorities and determine each property's band.

Your council collects the council tax, administers discounts and the Council Tax Reduction Scheme, and sends demand notices. But it has no authority to change your band. That power belongs solely to the Listing Officer.

This distinction matters because householders regularly send band complaints to their council, get a standard response explaining it's a VOA matter, and sometimes miss statutory deadlines in the process.

Informal Review vs Formal Proposal

These are two fundamentally different procedures, and confusing them is one of the most common mistakes in Welsh council tax challenges.

Informal band review — Anyone can ask for one at any time. You phone the Valuation Office on 03000 505 505 or write to it asking for a band check. There's no form, no statutory deadline, and no legal obligation to investigate or issue a formal response. If it decides your band is correct and declines to change it, you have no right to appeal to the Valuation Tribunal for Wales.

Formal statutory proposal — Available if you became the liable taxpayer within the last six months, if a notice of band alteration was served within the last six months, or under other specific statutory grounds such as a material reduction in value. A formal proposal under Regulations 5 and 6 of SI 1993/290 triggers the statutory process. The Listing Officer must acknowledge it within 28 days and decide it within four months. If the proposal is rejected or no decision is issued within four months, you can appeal to the VTW within four months of the decision notice or expiry of the decision period. This is the route with teeth.

The critical warning: spending weeks on an informal review can eat into your six-month window for a formal proposal. If you have statutory proposal rights, use them — don't start with an informal call.

How to Request Property Attribute Data

Before building a challenge, request your Property Attribute Data (PAD) from the VOA. This is free and shows the VOA's recorded details for your property — internal floor area, number of rooms, property type, age code, and any features that affect the valuation.

Request PAD by calling 03000 505 505 or through the online portal. Ask for the PAD of comparable properties on your street too — this helps you identify where the VOA's records differ from reality.

If the VOA has your floor area recorded as larger than it actually is, or lists features your property doesn't have, that's direct evidence of a potential banding error.

What a Formal Proposal Must Include

A valid proposal needs more than "I think my band is wrong." Under Regulation 6, you must provide:

• Your full name and address for correspondence
• Your capacity (owner-occupier, tenant, new taxpayer)
• The specific lower band you're requesting
• The legal ground for the alteration
• A detailed statement of reasons with comparable property addresses, sale dates and physical details A date if available; if the proposal is undated, the date the Listing Officer receives it is treated as its date. A signature, phone number, or email address is not a statutory requirement.

Missing a required detail can lead to an invalidity notice, giving you four weeks to correct the proposal or appeal the notice.

The 4-Month Decision Window

Since the February 2026 reforms (SI 2025/1323), the VOA has a four-month window to decide a formal proposal. If it accepts the proposal, your band changes. If it rejects the proposal, you have four months from when the decision notice is provided to appeal to the VTW; if no decision notice is provided, the four-month appeal period begins when the VOA's decision window expires.

One major change from the old system: cases no longer automatically transfer to the tribunal when the VOA misses its deadline. You must actively lodge an appeal yourself. Without that step, an expired decision window means your proposal simply stalls.

The Challenging Your Council Tax Band in Wales guide includes the VOA proposal checklist, PAD comparison templates, and deadline tracking tools to keep every step documented.
