How to Challenge NI Rates When an Extension Was Demolished or Never Recorded Properly

If your Northern Ireland rates bill is based on a capital value that includes a demolished extension, overstated floor area, or outbuildings that no longer exist, you have one of the clearest grounds for a valuation challenge. LPS must value your property based on its actual physical state — and if their records are wrong, the capital value is wrong. But before you file, you need to understand exactly what happens when LPS opens your property for a fresh assessment.

When Structural Records Are Wrong

The domestic capital-value baseline in Northern Ireland is 1 January 2005. LPS records property type, gross external area, construction era, and structural features; the baseline is not generally reset, but specific physical changes can still be reflected in the Valuation List when identified. If your property has physically changed — an extension was demolished, a garage was removed, subsidence reduced the usable area, or the original assessment simply measured the property incorrectly — the capital value on the valuation list may be overstated.

This is a factual error, and it's one of the strongest grounds for a statutory review under the Rates (Northern Ireland) Order 1977. You're not arguing about market conditions or rate poundages — you're saying the building LPS valued is not the building that exists.

The Two-Edged Sword: What LPS Checks When You File

A valuation review through Form CR3 is an open reassessment. LPS doesn't only look at the issue you raised — they reassess the property as a whole. This matters enormously when structural changes are involved, because it cuts both ways:

Changes that reduce your value:

• A rear extension was demolished after 2005
• A garage or outbuilding was removed
• The original gross external area was overstated on LPS records
• Severe subsidence or structural damage has permanently reduced habitable space

Changes that could increase your value:

• A loft conversion completed after 2005 that LPS never recorded
• A new conservatory, sunroom, or extension added since the original assessment
• Conversion of a single dwelling into multiple flats (triggers separate assessments)
• Any improvement that increased the gross external area

If you demolished a rear extension but added a loft conversion, LPS will adjust for both. The net effect could be a higher capital value, not a lower one.

How to Build Your Case

Step 1: Get your current LPS records. Look up your property on the LPS valuation search. Note the capital value, property classification, and any details shown. During an active review, you can request measurement summaries from LPS to see what floor area they have on file.

Step 2: Document the structural change. Photographs showing the current state of the property, before-and-after images if you have them, planning permission records, building control completion certificates, or demolition notices. If the original assessment was simply wrong (overstated floor area, wrong house type), measure your property's gross external area yourself and compare it to what LPS recorded.

Step 3: Run the upward risk diagnostic. Before filing Form CR3, audit every structural change to your property since 2005. List every extension, conversion, outbuilding addition, or improvement. If the unrecorded improvements outweigh the demolition or correction you're claiming, filing could result in a net increase.

Step 4: Gather comparable evidence. Even with a structural error, LPS will compare your property to similar properties in the area. If neighbouring properties with the same post-demolition footprint carry lower capital values, that strengthens your case.

Who This Is For

• Homeowners whose property has physically changed since 2005 — demolished extension, removed outbuildings, structural damage
• Ratepayers who believe LPS recorded the wrong property type, floor area, or structural layout
• Anyone whose capital value seems inconsistent with the property's actual size and condition
• Family members who inherited a property that was altered before they took ownership

Who This Is NOT For

• Temporary issues like minor flooding or cosmetic deterioration — LPS assumes average internal condition regardless
• Properties where the only change is market value decline — the 2005 baseline doesn't move
• Ratepayers in arrears — contact Advice NI for free debt advice before starting a valuation challenge

The Filing Route

For most householders, the route is Form CR3 submitted to LPS by post or email. If the initial valuation list entry is less than 28 days old, or you disagree with a District Valuer's Certificate of Valuation, use Form CR20 (Notice of Appeal to the Commissioner of Valuation). For an appeal against a Certificate, Form CR20 must reach LPS within 28 calendar days of the date printed on it.

LPS typically takes around 90 days to complete a review. A valuer may contact you; the review includes a physical inspection to record external measurements and verify structural features. You must continue paying your existing rates bill throughout the process — stopping payments triggers debt recovery regardless of an active review.

If LPS confirms or increases your valuation and you disagree, first appeal to the Commissioner of Valuation using Form CR20 within 28 calendar days of the Certificate date. If you still disagree with the Commissioner's decision, you can appeal to the Northern Ireland Valuation Tribunal using Form 3 within 28 calendar days of that decision, at no cost.

The NI Valuation Challenge Workbook includes the upward risk diagnostic, comparable evidence worksheets, and the form decision matrix — everything you need to assess whether filing makes sense for your specific structural situation before committing to the review.

Frequently Asked Questions

Will LPS inspect my property if I mention a demolished extension?

Yes. A physical inspection is part of the review. The valuer records external measurements and verifies structural features, so they will see the property as a whole — including any improvements you haven't mentioned.

What if the extension was demolished before 2005?

If the extension was gone before the 1 January 2005 valuation date, LPS should never have included it in the original assessment. This is a factual error in the valuation list, and it's a strong ground for correction. Provide any evidence you have of the demolition date — planning records, photographs, council correspondence.

Can I challenge just the floor area without triggering a full reassessment?

No. Any Form CR3 submission opens the entire property for review. You cannot limit the scope of what LPS examines. This is why the upward risk diagnostic matters — you need to know what LPS will find before they find it.

How far back can a refund be applied if LPS agrees the records are wrong?

The effective date depends on why the list is changed: a physical demolition takes effect from its actual date; a correction of a valuation error or successful appeal generally takes effect from the beginning of the rating year in which the review was lodged, or from the date the error occurred if it is within the current valuation list cycle. LPS recalculates the bills for the applicable years; any net credit can be refunded or applied to the account.
