Running a shop, salon or unit in Northern Ireland: what business rates actually cost a sole trader in 2026/27

By Buzz Accounting · 2026-11-04

If you trade as a sole trader from a shop, salon or workshop in Northern Ireland, your rates bill is worked out on a different system to the rest of the UK, and the amount you actually pay can depend as much on which council you're in as on the premises itself. Get the mechanics wrong and you either overpay without noticing, or assume a relief applies that your bill doesn't actually show.

This is a different system to England, Scotland or Wales — our Welsh business rates article covers the equivalent for a unit on the other side of the Irish Sea. Northern Ireland uses its own valuation basis, its own relief scheme, and its own administering body, and none of the three translate directly.

Net Annual Value, not rateable value

Northern Ireland doesn't use rateable value. It uses Net Annual Value (NAV) — a comparable idea, an estimate of the property's annual rental worth — set by Land & Property Services (LPS), not the Valuation Office Agency. Every non-domestic property was revalued on 1 April 2026 under Reval2026, based on April 2024 rental evidence rather than the October 2021 evidence used before, and values rose by around 15% overall. A revaluation is designed to be revenue-neutral across the system as a whole, so it redistributes who pays what rather than raising the total take — if your NAV rose by less than the 15% average, your relative share has actually fallen, even if the cash figure on the letter looks higher than last year's.

How the bill is built: two poundages, not one

Your gross bill, before any relief, is your NAV multiplied by a poundage made up of two parts added together: a regional rate, set once by the Northern Ireland Executive and identical everywhere, and a district rate, struck separately by each of the eleven councils. For 2026/27 the regional element is 0.3079. District rates vary enough that the combined poundage runs from 0.578402 in Fermanagh and Omagh, the lowest in Northern Ireland, up to 0.721635 in Derry City and Strabane, the highest — a gap that applies to identical premises purely because of where the front door happens to be.

Worked example: an identical £9,000-NAV salon, two councils

A sole trader hairdresser rents a small unit assessed at £9,000 NAV. Before any relief, the gross bill is NAV × poundage. In Fermanagh and Omagh, at 0.578402, that's £9,000 × 0.578402 = £5,205.62. In Derry City and Strabane, at 0.721635, the same £9,000 unit produces £9,000 × 0.721635 = £6,494.72 — £1,289.10 more, before relief, for an identical premises.

Small Business Rate Relief: automatic, but banded

On top of the poundage, most sole-trader-sized premises qualify for Small Business Rate Relief (SBRR), extended through to 31 March 2027, banded by NAV:

NAV £2,000 or less: 50% relief
NAV £2,001 to £5,000: 25% relief
NAV £5,001 to £15,000: 20% relief

SBRR is awarded automatically by LPS once a property's NAV is confirmed — there's no form to submit — though it excludes unoccupied and partly unoccupied property, ATMs, advertising displays, car parks, sewage works, telecoms masts and public bodies. Our £9,000 NAV salon sits in the 20% band on both examples above. In Fermanagh and Omagh, the 20% relief is worth £1,041.12, bringing the net bill to £4,164.49. In Derry City and Strabane, the same 20% relief is worth £1,298.94, bringing that bill to £5,195.77. The gap after relief, £1,031.28 a year for an identical unit, comes entirely from district poundage — the relief band doesn't close it, because the same percentage applies to a bigger starting number.

Automatic doesn't mean guaranteed

"Automatic" means LPS applies the relief without you submitting a claim form, not that it's certain to be on your bill correctly. It depends on your property being recorded accurately and genuinely eligible. If your bill shows no reduction and your NAV sits inside one of the three bands above, query it with LPS rather than assuming it's been handled — especially after a change of occupier, a new tenancy, or following Reval2026's wholesale reassessment of over 75,000 properties.

Taking on a long-empty unit: Back in Business

If you're a sole trader taking on premises that were previously used for retail and have stood empty for 12 months or more, a separate scheme, Back in Business, gives 50% off for up to two years, for occupations from 1 April 2024 onwards. Unlike SBRR, Back in Business is not applied automatically — you have to raise it with LPS yourself, so it's worth asking about explicitly before you sign a lease on a unit that's been sitting empty, not after the first bill arrives.

What to do this week

Find your property's NAV and council on your latest rates bill, and work out which SBRR band it sits in.
Calculate the gross figure yourself (NAV × your council's 2026/27 poundage) and check it reconciles to the bill before relief is applied.
If the SBRR percentage for your band isn't showing as a deduction, query it with LPS rather than assuming it's already included.
If you're taking on a unit empty for 12 months or more, ask about Back in Business before you sign — it won't be offered to you unprompted.
Keep the demand notice showing the net figure you actually paid; it's what goes through as a deductible expense against your trading profit, not the gross amount before relief.

Quick answers

About this post

Do sole traders in Northern Ireland pay business rates?

Only on non-domestic premises — a shop, salon, workshop, office or similar unit with its own Net Annual Value on the Land & Property Services register. Working from home as a sole trader doesn't normally bring you into the rating system unless part of the property is used exclusively and substantially for the business, which is a narrow test most home-based traders don't meet. If you occupy a unit with its own NAV, the figures in this article apply directly; if you work from a spare room, they generally don't.

What is Net Annual Value and how is it different from rateable value?

Net Annual Value (NAV) is Northern Ireland's equivalent of rateable value — an estimate, set by Land & Property Services, of what a property would rent for annually. It plays the same role rateable value plays in England, Scotland and Wales, but the two aren't interchangeable figures; NAV is set under separate legislation, revalued on its own schedule, and multiplied by Northern Ireland's own poundage rather than any GB multiplier. Comparing a Northern Ireland bill to a GB one by NAV and rateable value alone will mislead you, because the relief schemes built on top of each are different too.

Is Small Business Rate Relief automatic in Northern Ireland?

Yes — Land & Property Services applies it without a claim form, based on your property's Net Annual Value: 50% relief at £2,000 NAV or less, 25% between £2,001 and £5,000, and 20% between £5,001 and £15,000. Automatic isn't the same as guaranteed, though. The award depends on your property being correctly recorded and genuinely eligible, and it excludes unoccupied property, ATMs, advertising displays, car parks, sewage works, telecoms masts and public bodies. If your bill doesn't show the reduction your NAV band should produce, it's worth querying with LPS rather than assuming it's already applied.

How long does the current Small Business Rate Relief scheme run?

It has been extended through to 31 March 2027. Northern Ireland's rate support schemes, including Small Business Rate Relief, are reviewed and renewed on a rolling basis by the Executive rather than being set in permanent legislation the way some GB reliefs are, so there is no guarantee the bands or percentages carry over unchanged beyond that date. It's worth checking for a fresh extension announcement again as 31 March 2027 approaches, the same way you'd check before assuming last year's figures still apply automatically to a new financial year, rather than discovering a change only once a bill arrives without the relief you expected.

Why do two premises with the same Net Annual Value pay different rates bills?

Because the poundage has two parts, and only one is fixed. The regional rate, 0.3079 for 2026/27, is set once by the Northern Ireland Executive and applies everywhere. The district rate is struck separately by each of the eleven councils, and the combined poundage ranges from 0.578402 in Fermanagh and Omagh up to 0.721635 in Derry City and Strabane. A £9,000 NAV unit in each of those two councils produces gross bills of £5,205.62 and £6,494.72 respectively, before any relief — a location difference of over £1,200 a year for an identical property.

What is the Back in Business scheme and does it apply to me?

Back in Business gives 50% off rates for up to two years to a business taking on premises that were previously used for retail and have stood empty for 12 months or more, for occupations from 1 April 2024 onwards. It's separate from, and on top of, Small Business Rate Relief. Unlike SBRR, it is not applied automatically — you have to raise it with Land & Property Services yourself before or shortly after taking occupation, so it's worth asking about explicitly if you're a sole trader taking on a unit that's been sitting empty, rather than waiting to see if it appears on the first bill.

What happened to rates bills under Reval2026?

Reval2026 took effect on 1 April 2026 and rewrote every non-domestic Net Annual Value in Northern Ireland, based on April 2024 rental evidence rather than the October 2021 evidence used before. Over 75,000 properties were revalued and values rose by around 15% overall. A revaluation is designed to be revenue-neutral, so it redistributes the total rates burden rather than increasing it system-wide — if your NAV rose by less than the average, your relative share has fallen even if the cash figure on your bill looks higher than last year's. A rise well above the 15% average is worth querying rather than absorbing.

Does paying business rates reduce my Self Assessment tax bill?

Yes, indirectly. The net rates you actually pay, after Small Business Rate Relief and any other relief such as Back in Business, is a deductible business expense against your trading profit, the same as rent or utilities, and it reduces your taxable profit pound for pound. Keep the demand notice showing what you actually paid after relief — that net figure is what belongs in your accounts, not the gross amount the poundage alone would produce before any relief is applied.
