Medical Evidence for Disabled Persons Allowance in Northern Ireland

You've downloaded Form DPA 16.0 and started filling it in. Then you hit Section 4 — supporting evidence. LPS may ask for medical documentation, property evidence, and professional statements. What exactly do they need, and where do you get it?

The Two Tests DPA Evidence Must Cover

Disabled Persons Allowance requires you to prove two things simultaneously. Your evidence package must address both, or LPS will return the application incomplete.

The individual test: A person living in the property is substantially and permanently disabled, or has a mental disorder within the meaning of the Mental Health (Northern Ireland) Order 1986. This is the medical evidence component.

The facility test: The property contains at least one qualifying physical adaptation that meets the needs of that disabled resident. This is the property evidence component. It must show a room other than a kitchen, bathroom, or lavatory used wholly or mainly for treatment, therapy, or disability-specific needs; an additional kitchen/bathroom/lavatory; or adequate floor space for indoor wheelchair use.

Neither test is sufficient on its own. A strong GP letter with no property evidence fails. A detailed floor plan with no medical confirmation fails.

Medical Evidence: What LPS Accepts

For the individual test, common forms of supporting evidence include:

Disability benefit award letters are the simplest starting point. If the disabled resident receives Personal Independence Payment (PIP), Disability Living Allowance (DLA), or Attendance Allowance, the award notice can support the disability evidence. This doesn't guarantee DPA — it supports the individual test only — and the property must still meet the separate facility test.

A GP letter or medical practitioner certificate works when no disability benefit is in payment. The letter should confirm the resident's diagnosis and, where applicable, that the condition is substantial and permanent, then explain how it gives rise to the care or mobility needs that the property adaptations address. A letter that says "Mrs X has arthritis" is weaker than one that says "Mrs X has severe bilateral osteoarthritis resulting in permanent mobility impairment requiring level-access washing facilities and indoor wheelchair use."

Occupational therapist reports are particularly valuable because they bridge the medical and property evidence. An OT assessment typically covers the resident's functional limitations, the specific adaptations recommended, and how those adaptations meet the resident's disability-related needs. If an OT recommended the adaptation through the NIHE Adaptations Programme or a DfC Disabled Facilities Grant, that recommendation letter directly supports both tests.

Consultant or specialist reports can document complex or contested conditions — particularly where the disability is mental rather than physical (such as autism spectrum conditions requiring a dedicated sensory room).

Property Evidence: Proving the Adaptation Qualifies

Medical evidence alone won't carry the claim. LPS needs to see that the property has a qualifying facility under one of the three statutory categories.

Floor plans or architectural drawings showing the layout of the adaptation. For an additional bathroom (Category B), the plans should clearly show it as a separate facility beyond the property's original sanitary provision. For a room under Category A, the plans should show a room other than a kitchen, bathroom, or lavatory used wholly or mainly for the resident's treatment, therapy, or disability-specific needs.

Internal photographs of the qualifying facility. LPS may request these as part of their initial assessment. Photos should show the facility in its current state, demonstrating its purpose and relationship to the disabled resident's needs.

Building control completion certificates can document structural work. If a second bathroom or extension was built through a formal grant or adaptation programme, include any completion certificate you have.

NIHE or DfC grant approval letters are strong supporting evidence. If the adaptation was funded through a Disabled Facilities Grant or the NIHE Adaptations Programme, the approval letter confirms a professional assessment of the resident's needs and the adaptation's purpose.

The Occupational Therapy Report in Detail

An occupational therapy report is the single most useful document for a DPA application because it naturally addresses both tests. A well-structured OT report covers:

• The resident's diagnosis and functional limitations
• An assessment of how the disability affects daily living within the home
• The specific adaptations recommended and why they are essential
• How the room, added facility, or wheelchair space meets the statutory criteria (and, for Category B, adds rather than replaces a facility)

If you had an OT assessment through NIHE before the adaptation was installed, request a copy of the original report. If you don't have a formal assessment, contact LPS to confirm what supporting evidence it needs for your application.

What Doesn't Count as Evidence

LPS is specific about what the adaptation test requires. Evidence of modifications that fall outside the three statutory categories — external ramps, widened doorways, grab rails, stairlifts, or general mobility aids — does not support a DPA claim regardless of their medical necessity. The Court of Appeal confirmed this in Department of Finance v Mary Quinn [2019] NICA 41.

Similarly, replacing an existing facility (such as swapping a bathtub for a walk-in shower in the property's only bathroom) does not create an additional facility under Category B.

Putting the Package Together

A complete DPA evidence package typically includes:

1. Completed Form DPA 16.0
2. Disability benefit award letter or GP/specialist letter confirming the disability
3. OT report (if available) linking the disability to the specific adaptation
4. Floor plan showing the qualifying facility's location and purpose
5. Photographs of the adaptation
6. Any grant approval or building control documentation

Submit the supporting evidence with your application. Missing mandatory evidence can cause an application to be returned and delay the decision. Target processing time is 15 to 30 working days from receipt of an application.

Our Northern Ireland Rates Allowances guide includes a DPA evidence checklist you can print and work through before submitting — making sure nothing is missing before Form DPA 16.0 goes to LPS.
