Can a firm say it works with, or for, the Valuation Office?

No. The Valuation Office never recommends or endorses an agent, and never allows an agent to claim they're acting as part of, or on behalf of, the Valuation Office (GOV.UK, staying safe from scammers). Treat any claim of an official connection as a warning sign.

Is an upfront fee ever legitimate?

Some regulated firms charge fixed fees for defined work, such as a formal valuation report, and say so in writing. A fee demanded on a cold call before any work is described is not that.

What do RICS, RSA and IRRV membership actually give me?

Professional standards, a complaints route, and, for RICS-regulated firms, professional indemnity insurance. It doesn't guarantee a result, but it means someone is accountable.

Can I check whether a firm has submitted anything for my property?

Yes: log into your business rates valuation account on GOV.UK. It shows any Check or Challenge on your property and the agents authorised to act for you.

Is it safe to use a firm found through a comparison or referral site?

The same questions apply. A referral is only as good as the firm behind it, so verify the membership and the fee terms yourself.

How to Spot a Legitimate Business Rates Advisor

Why this matters

A business rates advisor asks you to sign an authority to act on your behalf with the HMRC Valuation Office, and to pay a share of any saving. That’s a normal arrangement with a regulated surveyor. It’s also exactly what a rogue operator asks for, and the paperwork can look the same. The difference is in the conduct, the fee terms and the accountability behind the firm.

The Valuation Office publishes its own checklist for choosing a business rates agent. The points below cover the same ground from the business owner’s side.

Red flags

An unsolicited cold call, especially one claiming to be from, or working with, the Valuation Office or your council. The Valuation Office never recommends or endorses an agent, and never allows an agent to claim they’re acting as part of, or on behalf of, the Valuation Office. Any firm implying an official connection is misrepresenting itself. See GOV.UK’s guidance on staying safe from scammers.
A fee demanded before any work is done. Legitimate no-win-no-fee representation charges nothing upfront. An “assessment fee”, “registration fee” or “lodgement fee” payable before a Check is submitted is the most common way businesses lose money to rogue firms: the fee is taken, and little or nothing follows.
Pressure to sign quickly. “The deadline is this week.” There is no single fixed deadline for submitting a Check on the 2026 list. Timing affects backdating, not eligibility. A firm that won’t let you take the agreement away to read is telling you something.
A guaranteed reduction. No one can guarantee an outcome. Reductions depend on evidence and the Valuation Office’s decision, and a Check can result in an increase if the property is under-assessed.
No RICS, RSA or IRRV membership. Chartered surveyors are regulated by the Royal Institution of Chartered Surveyors (RICS); rating specialists are often also members of the Rating Surveyors’ Association (RSA) or the Institute of Revenues, Rating and Valuation (IRRV). Membership brings professional standards, complaints procedures and, for RICS firms, mandatory professional indemnity insurance. Ask for the membership number and check it on the body’s public register.
A vague or hidden fee structure. If the agreement doesn’t state the percentage, what it applies to (annual saving, backdated refund, or both), how long it lasts and how to end it, don’t sign.
An open-ended or very long authority. Some agreements authorise the firm to act for you for the life of the rating list, or roll over automatically, with a fee due on any reduction from any cause, including ones you didn’t ask them to pursue.
No physical address or a name that keeps changing. Check Companies House for how long the company has existed and who runs it.

Questions to ask before signing

What is your RICS, RSA or IRRV membership number?
What is the fee percentage, and does it apply to the annual saving, the backdated refund, or both?
Is there any payment before a reduction is secured? Any charge if the case is unsuccessful?
What evidence would you rely on for my property, and do you think there’s any risk of an increase?
How long does the agreement run, and how do I end it?
Who exactly will act for me, and are they a qualified surveyor?

A legitimate firm answers all six without hesitation. For the fee questions in detail, see our guide on what to check before signing a no-win-no-fee agreement.

What a legitimate arrangement looks like

A named, qualified surveyor, with a RICS, RSA or IRRV membership you can verify.
A written agreement with the fee percentage, its basis, the term and the exit terms all stated.
No payment until a reduction is agreed.
An honest assessment before submission, including whether the case is worth pursuing at all and whether an increase is possible.
A clear explanation of the Check, Challenge, Appeal process, including that you could do it yourself. Our guide on whether you need a specialist to appeal covers when that’s the better route.

If you’ve already signed something you’re unsure about

Read the agreement for its termination clause and act on it in writing. If a fee was taken upfront and no work has followed, that may be a matter for your bank, Trading Standards, or the professional body if the firm claimed membership. You can also check your business rates valuation account on GOV.UK to see whether anyone has actually submitted a Check or Challenge on your property, and remove an agent’s authority there.

How this site fits in

This site is not a rates advisor and does not submit appeals. The free check indicates whether your rateable value looks out of line; if it does and you want a professional view, it can refer your case to independent surveyors regulated by RICS, on a no-win-no-fee basis. Apply the same six questions to them as to anyone else.
