Standard-rated goods and exempt dispensing. Get the apportionment wrong and you charge 20% on the whole price — which is the most expensive mistake available in this sector, and one nothing in your till system will ever flag.
VATHLT2190 sets a three-stage test. It asks whether the establishment qualifies as a body corporate under s.9 of the Opticians Act 1989; whether it is a qualified sole proprietor doing all the work; whether the dispensing is actually carried out by a qualified optician; and whether unqualified staff are directly supervised by one.
A spectacle sale is two supplies, not one. Getting the split right is worth more than everything else on this list put together.
The VAT positionAccounts that separate GOS income, private testing, dispensing and goods — because they behave nothing alike and are taxed differently.
Accounts and taxSight test fees and optical vouchers across four nations, and the backdating pattern that makes the cash flow unpredictable.
GOS incomeEngland £24.13. Wales £46.20 under WGOS 1. Scotland banded, from £46.53 for an undilated examination under 60 to £57.80 dilated. Northern Ireland £25.52. If you trade across a border, almost nothing carries across with you.

Since the High Court decisions in Leightons and Eye-Tech in the late 1990s, dispensing — the measuring and fitting — is accepted as a separate supply from the goods, and it is exempt when performed by either an optometrist or a dispensing optician. VATVAL12320 dates the change to 1995, following Leightons Ltd. So the price a patient pays covers standard-rated goods and exempt dispensing services, and the two have to be apportioned rather than treated as a single taxable supply.
You charge 20% VAT on the entire spectacle price with no exempt dispensing element at all. VATHLT2190 sets a three-stage test with four questions — whether the establishment qualifies as a body corporate under s.9 of the Opticians Act 1989, whether it is a qualified sole proprietor doing all the work, whether the dispensing is actually carried out by a qualified optician, and whether unqualified staff are directly supervised by one. Fail all four and the supply is wholly standard-rated. That is the single most expensive trap in the sector. For a practice of any size the annual figure runs well into five figures. Nothing in your till system or your accounts will ever flag it.
Yes, entirely, and VATHLT2190 confirms it is and always has been. The exemption covers the whole of the medical test — the sight test, slit lamp examination of the cornea, keratometry measurement of corneal curvature and the glaucoma test. The complication is never the test itself; it is the spectacles that follow it, where goods and dispensing have to be separated from a single price the patient pays. If your VAT return treats the test and the spectacles as one taxable stream, that is the first thing worth looking at.
It depends on the nation and, in England, on a determination that has not yet been made for the current year. England is £24.13, applying from 1 April 2025. Wales pays £46.20 under WGOS 1. Scotland is banded rather than a single fee — a primary eye examination for a patient under 60 undilated is £46.53, rising to £57.80 dilated. Northern Ireland is £25.52. Those are four genuinely different economics, not four versions of the same one. A practice trading either side of a border is running two businesses, and a group spanning nations cannot budget them on a single assumption.
Because the fee determination can arrive long after the year has started. The 2025/26 England fee was determined eight months into the year and backdated to 1 April 2025, with contractors told they need take no action. As at August 2026 there is no published 2026/27 England determination, so £24.13 remains operative with a retrospective uplift being the historic pattern. Planning on a fee that has not been set is difficult; planning on last year's and reserving for a backdated correction is not.
No, and you should be sceptical of anyone who does. There is no HMRC, NHS or GOC publication of goodwill, EBITDA or turnover multiples for optical practices. Any figure circulating in the trade press or from a broker is a market opinion rather than a verifiable fact, and it should be attributed to whoever is offering it. What we will do is model what actually drives value in your practice, which is a more useful exercise than applying somebody's multiple.
