How to challenge your Northern Ireland rates valuation

Published 13 September 2026 · 4 min read · Reviewed against official sources

Every domestic rates bill in Northern Ireland rests on a single number: the capital value that Land & Property Services has put on your home. If that number is wrong, every bill built on it is wrong too. The process for correcting it is straightforward but poorly understood, and the most common mistake is using the wrong route because of a deadline most people have never heard of.

First, understand what you are challenging

Capital value is not what your home would fetch today. LPS values every domestic property at what it would have sold for on 1 January 2005, assuming an average state of internal repair. That reference date has not moved since the last general revaluation, which is why a house that changed hands last year for £240,000 might carry a capital value of £150,000 or less.

This matters because a challenge argued on the basis of today's prices will fail. "My house isn't worth that" is not a ground for review. "My house was over-valued relative to comparable properties at the 2005 reference date" is. The whole exercise is about consistency with the valuation list, not about market conditions.

Review or appeal: the 28-day rule

There are two separate mechanisms, and which one is available to you is decided entirely by timing.

If your property has been valued or revalued within the last 28 days — typically because it is newly built, has been extended, or you have just received a notice of a fresh valuation — you can lodge a formal appeal to the Commissioner of Valuation. This is a statutory process with a hearing route if the initial decision goes against you.

If more than 28 days have passed since the property was last valued, that window has closed. You instead ask LPS for a valuation review, which can be requested at any time. A review is an administrative reconsideration by LPS itself, and if you disagree with its outcome you then gain a fresh right of appeal from that decision.

For the overwhelming majority of homeowners, whose properties were last valued years ago, the review is the only door open. That is not a disadvantage: it is quicker, informal, and free.

The grounds that actually work

Reviews succeed when they point to something specific. Vague dissatisfaction does not move a valuation. The grounds worth raising are:

A factual error about the property. The wrong number of bedrooms, a garage that does not exist, floor area overstated, an extension recorded that was never built. These are the cleanest wins because they are simply checked and corrected.
A material change to the property. Part of the building demolished, a room lost to damp remediation, a garage converted in a way that reduced rather than increased value. Changes that make the property smaller or worse are the ones that reduce capital value.
Inconsistency with comparable properties. This is the strongest argument in practice. If three similar houses on your street — same age, same type, similar size — all carry capital values markedly lower than yours, LPS has to explain why. The valuation list is public, so you can gather this evidence yourself before you apply.
A change in the surroundings. A new road, a demolished amenity, a persistent nuisance that did not exist at the reference date. These are harder to make stick but are legitimate.

Check the comparables before you apply

The single most useful thing you can do costs nothing: look up your neighbours. LPS publishes the capital value of every domestic property, searchable by address. Pick five or six properties that a reasonable person would say are like yours — same street or estate, same house type, similar age and size — and note their values.

If yours sits comfortably within that range, a review is unlikely to succeed and you may be better off spending the effort on a relief claim instead. If yours is a clear outlier, you have the core of your case, and you should say so plainly in the application: list the addresses and values, and ask LPS to explain the difference.

One caution. A review can move the value up as well as down. If the comparables show your property is under-valued, applying invites LPS to correct that in the wrong direction. Do the homework first.

How to apply

Valuation reviews are requested through nidirect, either online or by form, and you will need your rates account details and the property address. There is no fee. Include your comparable properties, any evidence of factual errors, and photographs if the point is about the physical state of the building.

Keep paying your rates while the review is in progress. A pending review does not suspend the bill, and arrears attract recovery action regardless of the outcome. If the value is reduced, the overpayment is credited back.

What happens next

LPS will either confirm the existing value, reduce it, or in rare cases increase it. If you disagree with a review decision, you have a fresh right to appeal to the Commissioner of Valuation, and beyond that to the Northern Ireland Valuation Tribunal. Most disputes are resolved at the review stage, and most of those that succeed do so on comparables or factual error.

A reduced capital value takes effect from the date the change is deemed to apply, and the difference is reflected in future bills and, where appropriate, refunded for the current year.

Is it worth doing?

The saving is proportional: capital value multiplied by the combined regional and district poundage. A reduction of £20,000 in capital value on a Belfast property saves something in the region of £180 a year, every year, for as long as you own the home. For a fifteen-minute application backed by comparables you can look up in an evening, that is a good return — but only if the comparables support you. If they do not, put the effort into checking your eligibility for Lone Pensioner Allowance or Disabled Person's Allowance instead, where the reductions are larger and the criteria are clear.
