If you trade as a sole trader from a shop, salon, workshop or unit in Wales, your business rates bill has quietly changed shape for 2026/27 — not just the amount, but the mechanics behind it. Wales has moved, for the first time, to a three-tier multiplier system similar to England's, on top of its existing small business relief. Get the interaction between the two wrong and you either overpay all year, or assume a relief applies that doesn't.
This is a different tax to the one covered in our Land Transaction Tax article. LTT is a one-off charge the day you buy or lease premises. Business rates are the annual bill for occupying them — and in Wales, for 2026/27, both the rate itself and the relief on top of it have moved.
The three multipliers from 1 April 2026
Every non-domestic property in Wales has a rateable value (RV), set by the Valuation Office Agency, broadly reflecting its annual open-market rent. Your gross rates bill before any relief is RV × multiplier. From 1 April 2026, Wales uses three multipliers instead of one flat poundage:
- Retail multiplier — 0.350 — for eligible shops and similar retail premises.
- Standard multiplier — 0.502 — for most other business premises, including salons, workshops and offices.
- Higher multiplier — 0.515 — for the largest properties by rateable value.
The standard multiplier falling to 0.502 is, on its own, the first reduction to the general multiplier in Wales since 2010. For a sole trader, which multiplier applies depends on what the property is used for, not what structure you trade through — a shop and a salon of identical rateable value can have different gross bills before relief is even considered.
Small business rates relief: the taper that actually decides most bills
On top of the multiplier, most sole-trader-sized premises qualify for small business rates relief, which is where the real saving sits:
- Rateable value up to £6,000 — 100% relief. Gross bill reduced to zero.
- £6,001 to £12,000 — relief tapers from 100% down to 0% on a straight line.
- Above £12,000 — no small business relief at all, full multiplier rate applies.
The scheme is capped at two properties per business in each local authority, so a sole trader expanding to a third unit in the same council area should not assume the new site qualifies automatically.
Worked example: two shops, same street, different rateable values
Illustrative figures, both using the 2026/27 retail multiplier of 0.350. Shop A, a sole trader selling homeware, has a rateable value of £5,500 — under the £6,000 cut-off. Gross bill: £5,500 × 0.350 = £1,925. Relief: 100%. Net bill: £0.
Shop B, two doors down, has a rateable value of £9,000 because it's a larger unit. Gross bill: £9,000 × 0.350 = £3,150. At £9,000, the taper sits exactly halfway between £6,000 and £12,000, so relief is 50%. Net bill: £1,575 — half of the gross figure, not the full exemption Shop A gets, purely because of £3,500 of rateable value.
Now compare a hairdresser with an identical £9,000 rateable value salon. A salon isn't retail, so it's rated on the standard multiplier of 0.502, not 0.350: gross bill £9,000 × 0.502 = £4,518, and the same 50% taper brings it to £2,259 — £684 more than the shop next door with the same rateable value, purely because of what the premises is used for. If you run a trade covered in our accountants for hairdressers guide, check which multiplier your premises actually sits on; it isn't always the one you'd assume.
The hospitality discount hairdressers and shops don't get
A separate 15% discount applies on top of all of the above, but only to occupied food and drink hospitality premises — pubs, restaurants, cafés, bars and venues wholly or mainly used for live music, capped at £110,000 of relief per business across Wales. It does not extend to hairdressers, retail shops, gyms, or professional services, however much they might feel like "hospitality" in the everyday sense. The relief is calculated on the net bill left after small business relief has already been applied, so the two reliefs stack rather than compete, for the businesses that genuinely qualify for both.
Transitional relief after the 2026 revaluation
Rateable values were revalued ahead of the 1 April 2026 multiplier changes, and some premises saw a real increase in RV as a result. Where a property's rates liability goes up by more than £300 because of the revaluation, transitional relief caps how much of that increase lands in any one year: you pay 33% of the additional liability in 2026/27 and 66% in 2027/28, reaching the full new liability only in 2028/29. This applies automatically where the trigger is met — it isn't something you claim separately, but it is worth checking your 2026/27 bill actually reflects it if your rateable value moved.
What to do this week
- Find your current rateable value on your latest rates demand, or on the Valuation Office Agency's register, and check which band it sits in.
- Confirm which multiplier applies to your premises — retail, standard or higher — based on actual use, not assumption.
- If your rateable value sits between £6,000 and £12,000, work out your taper percentage rather than guessing; it moves in a straight line, not in steps.
- If you run a food and drink business, check the 15% relief and the £110,000 group cap have both been applied to your bill.
- If your bill jumped sharply from last year, check whether transitional relief should be capping the increase — and query it with your local authority if it hasn't been.
None of this changes your Self Assessment or your VAT position — it's a local authority bill, not an HMRC one — but it's real cash out of the same business, and the multiplier-plus-taper system catches people who last checked their rates bill before April 2026. We flag the right band and multiplier for your premises as part of getting your numbers straight, alongside everything else. Fixed fees from £19 + VAT a month. Get started.
