Medical Certificate for Vehicle Adaptations in Ireland (2026 Guide)

Last updated: February 2026

Based on guidance from Revenue Ireland, the HSE, and Citizens Information.

What is a Primary Medical Certificate in Ireland?
A Primary Medical Certificate (PMC) is an official medical certificate issued by the HSE that confirms a person meets strict disability mobility criteria for the purposes of the Disabled Drivers and Disabled Passengers Scheme.

Primary Medical Certificate: At a Glance

• Issued by: HSE Senior Area Medical Officer
  
• Used for: Vehicle adaptation tax relief and supports
  
• Required for: Disabled Drivers Scheme Ireland eligibility
  
• Applies to: Drivers and passengers with severe mobility disabilities

Before You Start: Quick Checklist

1. Confirm you meet the strict medical criteria below
2. Do NOT ask your GP for this certificate
3. Contact your local HSE office for the correct form
4. Gather medical evidence before applying

If you or a family member needs a new vehicle or a vehicle adapted due to disability in Ireland, you’ll quickly hear about the PMC.

This medical certificate is one of the most important documents in the entire vehicle adaptation and tax relief scheme process. Without it, most vehicle adaptation grants, tax reliefs, and fuel supports simply aren’t available.

What Is a Primary Medical Certificate for Vehicle Adaptations in Ireland?

In Ireland, the main medical certificate linked to vehicle adaptation tax relief is the Primary Medical Certificate (PMC).

A Primary Medical Certificate (PMC) is an HSE-issued medical certification that confirms a person is severely and permanently disabled for the specific purposes of the Disabled Drivers and Disabled Passengers Scheme.

It is required to qualify for supports such as:

• Vehicle adaptation tax relief
  
• VAT and VRT refunds
  
• Motor tax exemption
  
• Fuel grant support (where applicable)
  

To access most government vehicle adaptation supports, you must hold this certificate first. 

It can be issued for drivers or passengers, depending on how the vehicle relief scheme is being used.

Through this scheme, you may be able to claim back or avoid certain taxes, including Vehicle Registration Tax (VRT), VAT on the purchase of a vehicle, and VAT on vehicle adaptation costs.

If you qualify, you may also receive extra benefits such as motor tax exemption, toll road fee exemption, and access to the fuel grant.

The scheme operates under the Disabled Drivers and Disabled Passengers (Tax Concessions) Regulations 1994 (SI 353/1994), as amended, and usually requires a valid Primary Medical Certificate.

Why the Primary Medical Certificate Is So Important

Vehicle adaptations such as wheelchair lifts, ramps, or hand controls can cost thousands of euro.

The Irish system links financial support directly to medical eligibility. Without certification, you generally cannot claim relief.

The scheme exists because extensively adapted vehicles can cost significantly more than standard vehicles due to specialised modifications.

Primary Medical Certificate Ireland Eligibility Criteria

To meet Disabled Drivers Scheme Ireland eligibility, you must meet specific legal medical criteria related to severe and permanent mobility impairment.

According to official guidance from Citizens Information, you must have a valid PMC confirming severe and permanent disability and one of the following applies:

• You are completely or almost completely without the use of both legs.
• You are completely without the use of one of your legs and almost completely without the use of the other leg to the extent that you are severely restricted as regards movement in your legs.
• You are without both hands or both arms.
• You are without one or both legs.
• You are completely or almost completely without the use of both hands or arms and completely or almost completely without the use of one leg.
• You are a person with restricted growth syndrome (dwarfism) and have serious difficulties with movement of your legs.

These criteria are defined in legislation and applied consistently by the HSE during medical assessment.

Practical note: The eligibility criteria are strict. A diagnosis alone (e.g., Multiple Sclerosis or Arthritis) is not enough. The condition must result in physical disabilities that meet one of the specific functional impairment categories listed above.

Who Can Apply Under the Disabled Driver Scheme?

Tax relief claims under the Disabled Drivers and Disabled Passengers Scheme can usually be made by:

• A driver who holds a valid Primary Medical Certificate (PMC)
  
• A passenger who holds a valid PMC
  
• A family member who lives with and is responsible for transporting a passenger with a PMC (subject to residency requirements)
  
• A registered charity that provides transport services to people with disabilities who hold PMCs
  

In most cases, only one vehicle per eligible driver or passenger can qualify under the scheme at any one time.

Does a Primary Medical Certificate Expire?

In most cases, a Primary Medical Certificate is permanent. However, in some situations, it may be reviewed if medical circumstances change or if required during scheme reassessment.

Can Your GP Issue This Certificate? (Important)

Generally no.

One of the biggest misconceptions in Ireland is that a GP or hospital consultant can issue this certificate.

In reality:

• You must apply through your local HSE office
  
• Assessment is carried out by a Senior Area Medical Officer (SAMO)
  
• Private doctors cannot complete the official assessment
  

This is a mandatory step before accessing the tax relief scheme.

How to Apply for a Primary Medical Certificate in Ireland (Step-by-Step)

Step 1: Request Application

Request an application form from your local HSE office or from the HSE service page for your area, and follow the instructions provided.

Step 2: Gather Medical Evidence

Examples include:

• Hospital letters
• Consultant reports
• Operation notes
• Imaging results (if relevant)

Step 3: Attend Your Medical Assessment

The Senior Area Medical Officer (SAMO) will base their decision on objective medical evidence.

Step 4: Decision Issued

If the SAMO confirms you meet the medical criteria, the certificate will be issued.

Step 5: Keep a Copy of Your Certificate

You will need to submit the original or a certified copy when applying for support or reliefs via the Revenue online service. Always keep a digital copy or photocopy for your records.

Step 6: Appeal If Needed

If your PMC is refused, you can appeal to the Disabled Drivers Medical Board of Appeal. You generally have 28 days to lodge an appeal. The Board allows for a second independent medical opinion.

Next Phase: Connecting with Revenue & NDLS

Once you have the PMC, you must interact with Revenue and the National Driver Licence Service (NDLS) to fully activate your benefits.

1. Applying to Revenue (The Scheme)

With your PMC in hand, you must apply to the Revenue Commissioners (specifically the Central Repayments Office) for admittance to the scheme.

• You can apply online via myAccount or ROS (Revenue Online Service).
• Alternatively, you can submit Form DD1 (Disabled Drivers and Passengers Scheme Application).
• You will need your PPS number, PMC, and IBAN for repayments.
• Upon approval, Revenue issues a Certificate of Approval. You give this to the dealer if buying a new car to get the VRT/VAT exemption upfront.

2. The Driving Licence & Code 101 (For Drivers)

If you are a driver applying for the scheme, your driving licence or learner permit must indicate that you need a vehicle with adaptations.

• You may need to visit an NDLS centre.
• You will need to submit a medical report form (NDLS form) completed by a doctor.
• Your licence may be updated with notation code 101 (or similar codes like 10, 15, 20, 25, 30, 35, 40, 45, 50 depending on the specific adaptation required).
• Code 101 generally indicates “not for hire or reward” but is often linked to the specific restricted licensing for medical reasons in the context of tax relief.

Vehicle Rules Under the Disabled Drivers Scheme

Under the scheme, there are important rules about vehicle use and ownership:

• The vehicle must normally be used for the benefit of the PMC holder
  
• The vehicle must be primarily used for transport needs linked to the disability
  
• Vehicle replacement rules apply (usually you cannot sell the vehicle for 2 years without refunding a portion of the tax relief)
  
• There may be restrictions if the vehicle is sold or disposed of within certain time periods
• The vehicle can be a new vehicle or a vehicle previously registered (imported), but it must be registered in the State for the first time in the applicant’s name to get full VRT relief upfront.
• If buying a second-hand Irish registered car, you may claim a repayment of the residual VRT.

Practical Note: Always check Revenue scheme rules before changing or replacing a vehicle under the scheme.

Do You Need Approval Before Buying or Adapting a Vehicle?

In many cases, yes.

If you buy or adapt a vehicle before scheme approval, you may not qualify for tax relief or reimbursement.

Revenue pre-approval or confirmation of eligibility is often strongly recommended before major vehicle purchases or adaptations.

What Counts as a Vehicle Adaptation?

If a vehicle is modified for a driver or passenger with a disability, the changes must match that person’s specific needs.

According to the official guidance by the Revenue, examples include:

• Hand controls  
• Swivel seats (driver and passenger) 
• Alterations to the vehicle’s pedal controls or manual transmission controls  
• Wheelchair / person hoist  
• Extension of seat rails  
• Wheelchair storage device 
• Complex and significant adaptations (e.g., lowered floors for wheelchair entry).
  

Some major wheelchair-access adaptations can qualify for higher relief categories.

Disabled Drivers Scheme Relief Rates (VRT, VAT, and Fuel Grant)

Under the Disabled Drivers and Disabled Passengers Scheme, the amount of VRT and VAT relief you can get depends on whether you are a disabled driver or passenger and how much the vehicle has been adapted.

Relief is subject to Revenue approval and scheme limits.

Maximum relief amounts include:

• Disabled driver: up to €10,000
  
• Disabled passenger: up to €16,000
  
• Specifically adapted vehicles (major adaptations): up to €16,000
  
• Extensively adapted vehicles (very high-cost adaptations): up to €22,000
  
• Wheelchair-accessible vehicles: up to €48,000 (driver) or €32,000 (passenger)
  

If you qualify for tax relief, you can also get the fuel grant.

Fuel grant payments support ongoing running costs for adapted vehicles.

Fuel grant is paid per litre, up to 2,730 litres per year.

Since May 2025:

• Petrol: €0.689 per litre
  
• Diesel: €0.596 per litre
  
• LPG: €0.167 per litre

How the Full Process Usually Works

Common Mistakes People Make

• Assuming GP letters are enough

They’re usually not, the HSE assessment is mandatory.

• Thinking diagnosis automatically qualifies

Not true. You must meet specific legal mobility criteria.

• Buying / adapting vehicle before approval

Can cause funding or tax relief issues.

• Not checking the “Notation Code”

Drivers must ensure their driving licence matches the medical requirements (e.g., automatic transmission only) to be valid for insurance and the scheme.
