The stamp duty refund industry has exploded in the UK over the past few years. Companies purchase Land Registry data, identify recent property buyers, and bombard them with marketing promising thousands of pounds in refunds. For many homeowners, the natural reaction is suspicion: it sounds too good to be true.
So is it a scam? The answer — like most things in tax — is nuanced. The underlying opportunity is genuinely real. But the way some firms market and execute it can range from mildly misleading to genuinely harmful.
The opportunity IS real
Let's start with the facts. HMRC's own guidance (SDLTM04010) confirms that Stamp Duty Land Tax is charged on land and buildings, not on moveable items included in the property purchase. These moveable items — carpets, curtains, white goods, furniture, garden items — are classified as chattels under the Finance Act 2003.
If your purchase price included chattels and you paid SDLT on the full amount without deducting their value, you overpaid. And HMRC provides a formal mechanism — overpayment relief — to claim the excess back within 4 years of the purchase date.
This is not a loophole. It's not an aggressive tax scheme. It's a straightforward application of existing tax law. The reason so many people overpay is that solicitors don't routinely advise on it, and HMRC's own forms don't prompt for chattel values.
The legal basis
Finance Act 2003, Schedule 4, Paragraph 4 requires the purchase price to be apportioned on a "just and reasonable" basis between land and other property. HMRC's guidance confirms chattels should be excluded from chargeable consideration.
But not all firms are trustworthy
The problem isn't the opportunity — it's the industry that has grown up around it. Both the Chartered Institute of Taxation (CIOT) and the Law Society have raised concerns about the practices of some claims firms. Here's what to watch for.
Red flags to watch for
Any firm that quotes a specific refund amount before reviewing your purchase details, TA10 form, and the actual chattels in your property is guessing. A letter claiming "you could be owed up to £15,000" on a £500,000 property is almost certainly inflating the figure. A realistic chattels refund on a £500,000 property might be £300-£600 for an unfurnished home, or £500-£1,500 for a furnished one.
"You must act within 14 days." "This is a limited-time offer." The actual deadline for claiming is 4 years from your purchase date — not 14 days from receiving a letter. Firms that create artificial urgency are trying to prevent you from doing your own research. Take your time. Compare options. Check for yourself first.
Some firms don't just claim for chattels — they push uninhabitable property claims or mixed-use reclassifications without proper surveys. HMRC has publicly stated that 95% of uninhabitable property claims are incorrect and is actively challenging them. These claims carry real risk: repayment, interest at 7.5%, and penalties up to 100% of the underpaid tax.

Most firms charge 25-50% of the refund. That's a wide range. A firm charging 50% of a £500 refund leaves you with £250. Some firms also add VAT on top, or have minimum fee clauses buried in the terms. Always ask for the full fee structure in writing before signing anything.
The stamp duty refund industry is largely unregulated. Anyone can set up a claims company and start sending letters. If the firm has no qualifications (RICS, CIOT, ICAEW), no professional indemnity insurance, and no regulatory oversight, you have no recourse if something goes wrong.
Green flags: what trustworthy firms look like
Not all claims firms are problematic. Here's what a reputable firm looks like:
- RICS-regulated surveyors who prepare professional chattel valuations based on inspection or detailed questionnaires
- Professional indemnity insurance that protects you if their advice turns out to be wrong
- Transparent fee structure explained in writing before you sign, including whether fees are charged on gross or net refund amounts, and whether VAT applies
- Willingness to work through your solicitor rather than asking you to sign documents you don't fully understand
- Honest about the range of likely outcomes rather than promising a specific amount
- Clear explanation of what they're claiming for — chattels only, not speculative uninhabitability or mixed-use claims
When claims go wrong: a cautionary example
The risks of using an unqualified claims firm are not theoretical. There are documented cases where clients have ended up worse off than if they'd never claimed:
A claims firm submits a chattel valuation that HMRC considers inflated. The refund is initially paid (HMRC's "process now, check later" approach). The firm takes its 40% fee immediately. Six months later, HMRC opens a compliance check, rejects the valuation, and demands repayment of the full refund plus interest. The client must repay HMRC the full amount, but the firm's fee is non-refundable.
Result: the client has paid the firm's fee AND repaid the refund with interest. They are financially worse off than if they had never made the claim.
This scenario is documented in guidance from the CIOT and Law Society, and is one of the key reasons both organisations urge caution with unregulated claims firms.
How to check for yourself first
Before engaging any firm — or deciding whether to claim at all — you can check your potential refund yourself in under 2 minutes. Our free refund estimator walks you through the chattels in your property and calculates a realistic estimate based on genuine second-hand values and the SDLT rates that applied at the time of your purchase.
This gives you a baseline figure you can compare against any quote from a claims firm. If a firm promises £5,000 but your own estimate shows £400, that's a significant red flag.
If your estimated refund is under £500, you can probably claim it yourself without paying a firm's percentage. For larger refunds, a vetted, qualified specialist can add value through professional valuations and handling the HMRC process.
The bottom line
Stamp duty refunds on chattels are real, legal, and HMRC-approved. The opportunity is genuine and applies to the vast majority of property purchases.
But not all firms marketing this opportunity are trustworthy. Some overstate refunds, charge excessive fees, and push high-risk claim types. The smartest approach: check your eligibility yourself first, understand the realistic numbers, and only then decide whether to use a firm or handle it yourself.
