VRT on Insurance Write-Offs — Complete Category Guide for Ireland
Everything you need to know about importing and registering insurance write-off vehicles in Ireland. Cat A, B, C, D, N, and S categories explained with VRT implications for each
Category Guide →Insurance Write-Off Categories Explained
Insurance write-off categories classify vehicles based on the extent and type of damage they have sustained. Understanding these categories is essential when importing a vehicle with a damage history to Ireland, because they determine whether the vehicle can be registered, what inspections are required, and how VRT is calculated. The UK's category system (Cat A, B, C, D, N, S) is the most commonly encountered for imported vehicles, though similar systems exist in other European markets.
Revenue assesses VRT on the vehicle's Open Market Selling Price (OMSP) at the time of registration. A vehicle with a recorded write-off history will have a reduced OMSP reflecting its damaged condition. The key is understanding which categories allow registration after repair and what documentation Revenue requires to process the VRT declaration.
Cat A — Scrap Only
Cat A vehicles have sustained total structural damage and must be completely crushed. No parts can be salvaged. These vehicles cannot be repaired, registered, or driven under any circumstances. Cat A write-offs have no road value and should not be purchased for import. Revenue will not accept a Cat A vehicle for VRT registration under any circumstances. The vehicle's identity is permanently removed from the vehicle register.
Cat B — Break for Parts
Cat B vehicles must be broken for spare parts, with the bodyshell destroyed. While some components can be reused in other vehicles, the structural shell cannot be returned to the road. Cat B vehicles cannot be registered for road use in Ireland. They have value only as a source of parts. If you purchase a Cat B vehicle expecting to repair and register it, you will be unable to complete the VRT process. The shell must be destroyed and cannot be re-registered.
Cat C — Repairable Write-Off (Pre-2017 UK Categories)
Cat C was the pre-October 2017 UK classification for repairable vehicles where the repair costs exceeded the vehicle's pre-accident value. While the UK replaced Cat C and Cat D with Cat N and Cat S in 2017, Cat C vehicles still appear on the market and can be imported to Ireland. Cat C vehicles can be repaired, inspected, and registered. You must provide evidence of the repair and the vehicle must pass an NCT test before Revenue completes registration. The OMSP will be reduced to reflect the vehicle's damage history and repaired condition.
Cat D — Repairable Write-Off (Pre-2017 UK Categories)
Cat D was the pre-2017 classification for repairable vehicles where repair costs were less than the vehicle's value, but the insurer decided to write it off for commercial reasons. Cat D vehicles typically had minor damage — cosmetic issues, light panel damage, or mechanical faults. These are the easiest write-off category for import because the structural integrity was never compromised. Cat D vehicles can be registered in Ireland after repair and an NCT test if required. The OMSP reduction is typically smaller than for Cat C or Cat S vehicles.
Cat N — Non-Structural Damage (Current UK Category)
Cat N replaced Cat D in October 2017 and covers vehicles with non-structural damage. This includes electrical faults, cosmetic damage, mechanical issues, interior damage, or light panel damage that does not affect the vehicle's structural integrity. Cat N write-offs are the most common on the UK used car market and are popular imports for Ireland. They are the easiest category to register because the structure is unaffected. A Cat N vehicle needs condition assessment and an NCT test if 4 years or older. The OMSP adjustment is relatively modest, typically 10-25% below an equivalent clean vehicle.
Cat S — Structural Damage (Current UK Category)
Cat S replaced Cat C and covers vehicles with structural damage that can be repaired. Structural damage includes chassis rail damage, suspension mounting point damage, pillar damage, or floorpan distortion. Cat S vehicles require professional repair by a qualified bodyshop and must pass a full NCT test before registration. Revenue will require evidence of the repair, including photographs, invoices, and the NCT pass certificate. The OMSP reduction for Cat S vehicles is substantial, typically 30-50% below an equivalent clean vehicle, reflecting both the damage history and the cost of repairs already carried out.
VRT Calculation for Write-Off Vehicles
VRT on a write-off vehicle is calculated on the vehicle's OMSP in its current condition at the time of registration. This is the key difference from buying a clean vehicle — the OMSP is adjusted downward to reflect the damage history and any repairs carried out. Revenue's VRT assessors will inspect the vehicle and assess its value based on its actual condition, not its pre-accident value.
The VRT calculation follows the standard formula: OMSP × VRT rate (based on CO2 emissions) minus any applicable reliefs (such as EV or PHEV relief). The OMSP is the critical variable — a Cat S vehicle might have a pre-accident OMSP of €20,000, but Revenue may assess it at €12,000-€14,000 after accounting for the structural damage and repairs. This lower OMSP means proportionally lower VRT, though the absolute saving depends on the CO2-based rate.
For example, a Cat N Volkswagen Golf with 120g/km CO2 and a clean OMSP of €18,000 would have a pre-damage VRT of €3,240 (18% rate). After a Cat N adjustment to €14,500 OMSP, the VRT becomes €2,610 — a saving of €630. A Cat S version of the same car with an OMSP of €11,000 would have VRT of €1,980 — saving €1,260. These savings partially offset the cost of repairs you have already carried out.
Importing Write-Off Vehicles from the UK
The UK is the primary source of write-off vehicles imported to Ireland. Since Brexit, the process for importing a UK write-off has changed, but it remains viable and popular. Here is what you need to know:
Documentation Requirements
When importing a write-off vehicle from the UK, you need the V5C logbook showing the write-off category, proof of purchase (invoice showing the sale price and damage description), photographs of the vehicle before and after repair, invoices for all repair work carried out, and the NCT pass certificate. If the vehicle was repaired in the UK, you also need the UK equivalent of an NCT (MOT certificate if it was tested after repair). Revenue may request additional documentation if the repair work appears extensive.
Customs and VAT Considerations
Since Brexit, vehicles imported from the UK are subject to customs duty at 10% of the purchase price (or the vehicle's value, whichever is higher), plus VAT at 23% on the total of the purchase price plus customs duty plus shipping. The write-off status does not change the customs or VAT treatment — you pay the same import duties as a clean vehicle. However, on a lower purchase price (reflecting the damage history), the absolute customs duty and VAT are lower than for an equivalent clean vehicle.
Shipping and Transport
Write-off vehicles can be shipped from the UK to Ireland via ferry services from Holyhead to Dublin, Fishguard to Rosslare, or Liverpool to Dublin. Shipping costs typically range from €200-€500 depending on the port and whether the vehicle is driveable. For non-driveable write-offs, you need a recovery vehicle or trailer transport. Factor this into your total import cost calculation.
NCT Requirements for Write-Off Vehicles
The NCT test is a critical step in registering a write-off vehicle in Ireland. For vehicles 4 years or older, a valid NCT certificate is mandatory before Revenue will complete the VRT registration. For write-off vehicles, the NCT serves an additional purpose — it confirms that the repairs have been carried out to a roadworthy standard and the vehicle is safe to drive.
Key NCT considerations for write-off vehicles:
- Cat N vehicles — Standard NCT test required if 4+ years old. No special inspection beyond the standard test.
- Cat S vehicles — Full NCT test required. The inspector will pay particular attention to structural integrity, weld quality, and alignment. Some NCT centres may refer Cat S vehicles for a more detailed inspection.
- Cat C vehicles — Same as Cat S. Full NCT required with close attention to structural repairs.
- Cat D vehicles — Standard NCT test. The damage was non-structural, so the test follows normal procedures.
- Cat A and Cat B — Cannot be NCT tested because they cannot be registered or driven. No point in the process.
If the NCT test reveals issues with the repair work, you will need to have the faults corrected and the vehicle retested before you can proceed with VRT registration. Budget for potential rework and retest fees (€55 per test) when planning your import.
Insurance Implications for Write-Off Vehicles in Ireland
Insuring a write-off vehicle in Ireland is more complex than insuring a clean vehicle, but it is possible. Here is what you need to know:
Most Irish insurers will insure Cat N and Cat D vehicles on standard policies, provided the vehicle has a valid NCT and has been properly repaired. Some insurers may ask about the vehicle's damage history during the quotation process. You should always disclose the write-off history — failing to do so could invalidate your insurance. Cat S and Cat C vehicles are harder to insure. Some specialist insurers cover them, but premiums are typically 20-40% higher than for an equivalent clean vehicle. You may need to shop around for quotes from multiple providers.
Cat A and Cat B vehicles cannot be insured for road use because they cannot be registered. They have value only for parts or as off-road projects. If you are considering a Cat A or Cat B vehicle for a track car or off-road use, you do not need VRT or insurance for road use, but you also cannot drive it on public roads under any circumstances.
Common Mistakes When Importing Write-Off Vehicles
Importing a write-off vehicle can save money, but common mistakes can turn a bargain into a financial disaster. Here are the most frequent errors and how to avoid them:
- Buying Cat A or Cat B without realising: Always check the V5C logbook or equivalent documentation for the write-off category before purchase. Cat A and Cat B vehicles cannot be registered in Ireland under any circumstances.
- Underestimating repair costs: Get a professional inspection and repair quote before buying a Cat S or Cat C vehicle. Repair costs often exceed the price difference between the write-off and a clean vehicle.
- Missing NCT implications: Factor in NCT test fees, potential retest fees, and the cost of any rectification work the NCT identifies. Budget €200-€500 for NCT-related costs on a repaired write-off.
- Not budgeting for insurance premiums: Get insurance quotes before committing to purchase. Write-off vehicles can be significantly more expensive to insure than clean vehicles.
- Ignoring the OMSP adjustment: The lower OMSP on a write-off means lower VRT, but the OMSP reduction may not fully offset the repair costs you have already incurred. Calculate your total cost including purchase price, repairs, shipping, customs, VAT, VRT, and insurance before deciding.
Step-by-Step Process for Importing a Write-Off Vehicle
- Check the write-off category — Verify it is Cat N, S, C, or D (not A or B). Request photographs and a damage description from the seller.
- Arrange a professional inspection — Have a mechanic or bodyshop assess the damage and provide a repair cost estimate before purchase.
- Purchase and arrange shipping — Complete the purchase, obtain the V5C and any repair documentation, and arrange ferry transport to Ireland.
- Complete customs clearance — Pay customs duty (10%) and VAT (23%) on the vehicle's total landed cost. Use our customs duty calculator to estimate these costs.
- Carry out repairs — Complete all necessary repairs. Keep all invoices and photographs as evidence. Use a VAT-registered repairer if possible so you can reclaim VAT.
- Book and pass NCT test — If the vehicle is 4+ years old, book an NCT test. For Cat S/C vehicles, ensure the structural repairs are properly documented.
- Submit VRT declaration — Complete the online VRT declaration with Revenue, declaring the vehicle's condition and attaching evidence of the write-off status and repairs.
- Attend VRT inspection — Bring the vehicle to the NCTS centre for identity and condition verification. Revenue's assessor will determine the OMSP based on the vehicle's actual condition.
- Pay VRT and register — Pay the assessed VRT amount. Revenue will issue the registration certificate and Irish plates.
- Arrange Irish insurance — Get an Irish insurance policy quoting the vehicle's registration number. Shop around for the best premium on a write-off vehicle.

VRT Insurance Write-Off FAQs
Can I VRT a Cat N write-off in Ireland?
Yes, Cat N (non-structural damage) write-offs can be VRT'd and registered in Ireland. Cat N is the easiest write-off category to import because the vehicle's structural integrity is unaffected. You need to repair the non-structural damage (cosmetic, electrical, or mechanical), pass an NCT test if the vehicle is 4 years or older, and declare the vehicle's condition accurately in your VRT application. Revenue will assess the OMSP based on the vehicle's repaired condition, typically 10-25% below a clean equivalent.
Can I VRT a Cat S write-off in Ireland?
Yes, Cat S (structural damage) write-offs can be VRT'd and registered in Ireland after proper repair. You must have the structural damage professionally repaired by a qualified bodyshop, keep detailed documentation including photographs and invoices, pass a full NCT test (the inspector will closely examine all structural repairs), and declare the vehicle's condition accurately. The OMSP will be significantly reduced, typically 30-50% below a clean equivalent. Cat S vehicles require more documentation and scrutiny than Cat N vehicles.
Can I VRT a Cat C write-off in Ireland?
Yes, Cat C (repairable write-off from the pre-2017 UK system) can be VRT'd and registered in Ireland. Cat C vehicles had repair costs exceeding the vehicle's pre-accident value. They require professional structural repair, full documentation of the repair work, a valid NCT pass certificate, and accurate declaration of the vehicle's condition. The OMSP reduction for Cat C is similar to Cat S (30-50%). The process is the same as for Cat S vehicles.
Can I VRT a Cat D write-off in Ireland?
Yes, Cat D (repairable write-off from the pre-2017 UK system) can be VRT'd and registered in Ireland. Cat D vehicles had minor damage where repair costs were less than the vehicle's value. They are similar to Cat N write-offs and are the easiest category to import. Standard repair documentation and an NCT test (if 4+ years old) are required. The OMSP reduction is typically modest at 10-25% below a clean equivalent.
Can I VRT a Cat A or Cat B write-off in Ireland?
No, Cat A and Cat B write-offs cannot be VRT'd or registered for road use in Ireland under any circumstances. Cat A vehicles must be completely destroyed with no parts salvaged. Cat B vehicles can only be broken for parts with the shell destroyed. Neither category can be repaired, inspected, or registered. If you import a Cat A or Cat B vehicle, it cannot be put on Irish roads. These vehicles have value only as parts donors or off-road projects.
Do I need an NCT for a write-off vehicle VRT?
If the vehicle is 4 years or older, yes — you need a valid NCT certificate to complete VRT registration. For write-off vehicles, the NCT is especially important because it confirms the repairs have been carried out to a roadworthy standard. Cat S and Cat C vehicles will receive extra scrutiny during the NCT test, with particular attention to structural repairs, weld quality, and alignment. If the vehicle is under 4 years old, an NCT is not required for VRT registration.
How is VRT calculated on a repaired write-off?
VRT on a repaired write-off is calculated based on the vehicle's OMSP at the time of registration, not its pre-accident value. Revenue's assessor will inspect the vehicle and determine an OMSP that reflects its actual condition, including the damage history and any repair work. The lower OMSP means lower VRT, but the saving depends on the CO2-based VRT rate. A Cat S vehicle with a significant OMSP reduction will pay proportionally less VRT than a clean equivalent. The VRT rate itself (based on CO2) is not affected by the write-off status — only the OMSP changes.
Can I import a UK Cat S car to Ireland?
Yes, UK Cat S cars can be imported to Ireland. The process requires: proper documentation including the UK V5C showing the Cat S marker, evidence of professional structural repairs, photographs before and after repair, a valid UK MOT certificate (if tested after repair), successful NCT test in Ireland, and accurate VRT declaration. The UK Cat S marker is recognised by Revenue and does not prevent registration as long as the vehicle has been properly repaired. Many Cat S vehicles from the UK are successfully imported and registered in Ireland every year.
Will my insurance be valid on a write-off vehicle in Ireland?
Insurance on write-off vehicles in Ireland depends on the category. Cat N and Cat D vehicles are generally insurable on standard policies if they have a valid NCT and were properly repaired. You must disclose the write-off history during the quotation process — non-disclosure could invalidate your policy. Cat S and Cat C vehicles are harder to insure; some mainstream insurers may decline cover, and specialist insurers charge higher premiums (typically 20-40% more). Get insurance quotes before committing to purchase a Cat S or Cat C vehicle. Cat A and Cat B vehicles cannot be insured for road use.
How does VRT on a write-off compare to buying a clean car?
A write-off vehicle will have lower VRT than a clean equivalent because the OMSP is reduced to reflect the damage history. However, you must factor in the cost of repairs, NCT fees, potential retest fees, higher insurance premiums, and additional documentation costs. A Cat N or Cat D vehicle can save €500-€1,500 in VRT compared to a clean equivalent, which may offset the lower purchase price and repair costs. Cat S and Cat C vehicles save more in VRT (€1,000-€3,000) but the repair costs are significantly higher.
