Who pays: owner or occupier

Short answer: Rates are a property tax paid to fund council and Assembly services, and the bill goes to the occupier unless the law moves it to the owner. The law moves it to the owner for low-value property and for short rent intervals.

Rates are a property tax that funds services at both local (council) and regional (Northern Ireland Assembly) levels (T27). The district rate is set by a council resolution and the regional rate by a Department order (L72). The governing statute is the Rates (Northern Ireland) Order 1977, and you read your own position from it.

Start with the default. A person who occupies the premises is the one assessed for the year (see "The part-year bill when you take over" below for how a part-year is counted). The Order then lists cases where the owner is rated instead of the occupier. Under Article 20(1) the owner pays where any one of these holds (T6):

• net annual value (NAV, the rental-value figure on which the bill is built) does not exceed £750;
• capital value does not exceed £150,000;
• rent is paid or collected at intervals shorter than quarterly, or the tenancy does not say when it is payable, and the NAV does not exceed £1,590;
• separate parts are let as apartments or lodgings;
• the property is or includes a house in multiple occupation.

Where a property has both a net annual value and a capital value, Article 20(1A) applies: the capital value limit and the £1,590 limit must both be met, and the rent-interval condition does not apply (T6).

For a shop or office you rent, the practical reading is the table nidirect publishes, which tracks those limits (N051).

The last row matters if you are buying a business that pays rent quarterly on a premises of any real size, which is the usual pattern for a shop. The nidirect table gives no answer for that row (N052). Reading the Order, the position is that Article 20 does not list that case, so the owner is not moved into the bill by Article 20(1). Treat that as a conclusion to confirm, not as the law: ask LPS in writing who the ratepayer is for that property, and keep the reply with your purchase papers.

The limits are not permanent. The Department can change the £750, £150,000 and £1,590 limits by order, and a change does not affect liability for periods before the next valuation list takes effect (T9). Check the current numbers on the day you complete.

An owner who is rated under Article 20 also gets the same non-occupation relief an occupier would have had (T7). A person who wilfully enters a property to take possession or use it without the owner's permission becomes liable instead of the owner for the low-value and house-in-multiple-occupation cases (T7). That rule matters if the seller's premises were occupied by someone with no lease.

An owner who pays on time receives a 10% allowance, with the deadline being the later of half the rating year or one month after the demand note is served (T8). If you are the incoming owner-landlord of a unit that falls under Article 20, that allowance belongs to your cash-flow plan, and the late-payment date is a calendar entry you should set on day one.

If you want to see the kind of ratepayer and landlord records a purchase check turns up, the sample report shows the layout, including the premises and landlord lines that decide who the ratepayer is.

The part-year bill when you take over

Short answer: The year runs 1 April to 31 March, and the bill is split by days. You pay for the days you occupy, not for the whole year, even when the bill was issued in April in the seller's name.

LPS issues rates bills at the start of April for 1 April to 31 March. If the person paying changes mid-year, LPS reassesses the rates from when the new person owns the property (N055). The statutory rule underneath is Article 19(2) of the 1977 Order: an occupier for only part of the year is liable for the share of the rate that matches the days of occupation to the total days in the year (T11). An occupier who left before the rate was made can still be assessed on that basis (T11).

The order of events at a handover is different from the order of events at a normal bill. An occupier arriving after the rate was made may be assessed and must initially pay either the full amount, if in occupation at the start of the year, or a proportion calculated as if staying to the year end (T12). So the first demand to you can be for the proportion up to 31 March, not for the days only up to a date you choose.

Worked example, with illustrative figures (not a real bill). The rating year is 1 April 2026 to 31 March 2027, 365 days. The annual rates bill for the premises is £6,000. You take over on 1 September 2026.

If the seller has already paid the whole year in advance, your £3,484.93 share is the amount the seller would reclaim from you in the price adjustment, not from LPS. Put that line in the completion statement and name the year it covers. Where the seller leaves early, the Order lets an overpayment above the part-year share be recovered from the Department, with two limits: no allowance for a period under seven days, and no recovery of sums already recovered from an incoming occupier (T12).

Two practical consequences follow. First, a takeover three days after a handover date can fall inside the seven-day limit if you rely on LPS to refund the days. Secondly, a bill in the seller's name on your desk on day one is not your liability for the days before 1 September. Ask LPS for the account statement for the current year before you complete (question 1 in "Questions for the seller").

If you want to see how the register and account lines for a premises are laid out before you pay for anything, the sample report walks through them.

Landlord and tenant: passing the rates on

Short answer: Whoever LPS bills, the lease can move the cost. Rent is treated as including rates in some leases unless the lease says otherwise, so the clause that matters is the one that says who pays.

Article 25 of the 1977 Order is headed "Incidence of rates as between landlord and tenant" and applies in the circumstances set out in Schedule 8 (L73). Schedule 8 is where a buyer of a tenanted property or a leasehold business finds the passing-on rules.

The rules in Schedule 8 are short and each one changes money:

• No deduction (paragraph 1). An occupier cannot deduct any part of a rate from rent, except as the Order provides (T1).
• A contract can move the cost (paragraph 2). A contract or covenant may require one person to pay another's rates, whether by rent deduction or otherwise (T2).
• Owner bills, tenant repays (paragraph 3(1)). Where the owner pays rates under Article 20 on a tenanted property, the tenant repays the owner the rates the tenant is liable for under the tenancy contract, and unpaid sums on demand are recoverable as rent arrears (T3).
• Inclusive rent (paragraph 3(2) and (3)). In a contract made after Article 20, rent is treated as inclusive of rates unless the contract shows otherwise, and if rates rise or fall the rent adjusts by the change attributable to the rent period (T4).
• Revaluation changes (paragraph 4). Where a change in law alters the rateable value, the tenancy predates the change, the landlord agreed to pay the rates and the rent includes an amount for them, a fall in rates goes back to the tenant by payment or deduction and a rise is paid by the tenant to the landlord (T5). Disputes over the amount go to the Lands Tribunal (T5).

For your decision as a buyer, these rules read this way. If you take an assigned lease, read the rent clause and the rates clause together and find which of the two paragraphs 3 and 4 your lease falls in, by its date. If your lease includes rates in the rent and was made after Article 20, a revaluation can change your rent in either direction, by the difference attributable to the rent period (T4, T5). If the landlord pays the rates and you pay rent that includes an amount for them, a rise at the next valuation list passes through to you under paragraph 4 (T5).

Arrears matter in a different way. Unpaid sums that the tenant owes the owner for rates paid are recoverable as rent arrears (T3). When you take an assignment, ask the landlord for a statement showing rent and any rates recharged, by period, before you sign (question 4 in "Questions for the seller").

The sample report shows what a landlord line and a charges line look like for a premises, which helps you know what to ask the landlord to confirm in writing.

For the lease itself, put one question to your solicitor: "Under this lease, who pays rates, and does the rent clause include an amount for them, given the lease date?" The answer decides which paragraph of Schedule 8 governs.

Telling Land and Property Services

Short answer: Phone LPS on the day you take over. The owner must report a change of ownership immediately, and nidirect says a late report means a rates bill for the property.

For non-domestic or rented property nidirect says to phone LPS on 0300 200 7801 rather than use the online form to open a rates account (N054). The duty to report a change of owner sits on the owner: when a property owner changes, the owner must tell LPS immediately or you will get a rate bill for the property (N053). Do not assume the seller's solicitor has done it for you.

How the report is made depends on which account the landlord holds. A landlord with an Article 20 account phones LPS to report the change. A landlord with an Article 21 account sends LPS a copy of the solicitor's letter showing the date of sale and the new owner's contact details, or those of their solicitor or estate agent (N053).

Article 21 is an agreement, not a default. An owner whose rent is paid or collected at intervals shorter than quarterly may agree in writing with the Department to pay the rates whether the property is occupied or not, with an allowance of up to 10% if paid on the agreed dates (T10). The agreement binds a new owner, so if you buy a let property with an Article 21 agreement you take it over (T10). The agreement runs until either party ends it by notice. A termination notice takes effect only at the end of a year and must be given at least six months before that year ends (T10).

Your steps as the new owner of a let property are these: phone LPS with the sale date; ask which account type the property has; ask for the next payment dates; and if the account is under Article 21, ask for a copy of the agreement. If you want out of an Article 21 agreement, the notice must reach the Department at least six months before the year ends, so a purchase in autumn leaves a short window to serve it before 31 March (T10).

The Reval2026 team can be reached at nireval2026@finance-ni.gov.uk or 0300 200 7801 for property-identification and valuation queries (C67). That is a different team from the account line, so keep the two calls separate.

Unpaid rates, demand notes and recovery

Short answer: Unpaid rates are a debt that LPS can chase in court, and a dispute over a valuation matter that could have been raised by appeal or review is not open in that court (Article 32(7)). Before you complete, get the account statement and agree who pays the seller's arrears.

What an unpaid bill is in law. The whole rate is a debt due to the Crown (E14). Article 32 says a sum owed to the Department for a rate is recoverable as a debt, either summarily or by action in the county court or High Court (E5). A magistrates' court or county court can hear the claim even if limits in other provisions tied to the amount or the property's value would otherwise stop it (E5).

For a buyer, the conclusion is that the debt is owed by the person liable for the rate for the period, and Article 32 refers to "a person" who owes it (E5). The Order text does not say that the debt passes to a buyer of the premises. That does not make the arrears harmless to you, for the reasons below.

Why a seller's arrears can still reach you. Two routes bring them to you.

• Charge on land. LPS can ask for an Order Charging Land, which recovers the debt if the property is sold (E11). Ask LPS to confirm in writing whether any charge is registered before you complete.
• A bill you did not expect. If the owner changes and nobody tells LPS, nidirect says a rate bill for the property follows (N053, section 4).

Ask for the account statement and for LPS's written confirmation on charges. Illustrative figures: arrears you could inherit in practice. The seller's 2025-26 bill at NAV £12,000 in Belfast was £7,519.20 (12,000 x 62.66 / 100). Suppose the seller paid nothing and you complete on 1 October 2026. Your own part-year charge for 2026-27 is £3,891.11 (7,803.60 x 182 / 365). If the seller's arrears and your share were both unpaid on the day LPS acted, the account would show £7,519.20 + £3,891.11 = £11,410.31. Only the second sum is yours. Check: 7,803.60 x 182 / 365 = £3,891.11.

The pricing point: ask for a retention from the purchase price at least equal to the seller's unpaid balance, released when LPS confirms the account is clear.

Sums that suit a contract clause. An agreement on completion should settle four things, each in plain words:

1. Which days the seller pays and which the buyer pays, counted from the completion day.
2. The retention, its amount, and the proof that releases it.
3. Who deals with LPS about arrears for periods before completion.
4. What happens if LPS bills the wrong person, and who pays the extra costs of a court process.

Illustrative figures: on completion day the rates for the year to date are split by days. For a 365-day year and a £7,803.60 bill, if the seller prepaid the whole year and completion is on 1 October, the buyer owes the seller 182 days, which is £3,891.11 (7,803.60 x 182 / 365). Use the full-year bill times days over 365 when the contract says "pro rata", not a rounded daily rate.

Ask LPS, not only the seller. The seller's papers show what the seller says. LPS shows what the account holds. If the two differ, the account wins in court, because the certificate is evidence of the matters it states (E6). Phone LPS on 0300 200 7801 for non-domestic accounts (N054), and send a written follow-up that records the date and the name of the person you spoke to.

Questions for the seller

Short answer: Seven requests, each tied to a document and a period. Keep the replies with the sale papers.

1. LPS account statement for the current rating year (1 April to 31 March) and the prior year, showing demands, payments, any arrears, and the account type (Article 20, Article 21 or standard occupier).
2. If the account is under Article 21, a copy of the written agreement with the Department and any notice served to end it, with the date the notice was served.
3. Every valuation certificate, notice of decision and appeal notice for the premises over the last 12 months, with the date each was served, and any Commissioner decision.
4. Landlord statement for the last 12 months showing rent and any rates recharged, by period, and the lease clause that sets who pays rates (for a leasehold business).
5. LPS confirmation of the reliefs received for the premises in the current year, with the date each was granted and the condition attached.
6. The LPS statement of arrears by year, written confirmation from LPS that no Order Charging Land is registered over the premises, and the date of the seller's last payment.
7. For the day of completion: the date of the LPS call that reports the change of owner or occupier, and the name of the person at LPS who took it.
