NHS Pension Scheme ill-health retirement can allow an eligible member who is permanently unable to continue working because of illness or injury to take pension benefits before normal pension age.
It is not the same as ordinary early retirement, and a simple “ill-health retirement calculator” cannot decide eligibility. The decision depends on medical evidence and the NHS Pension Scheme’s Tier 1 or Tier 2 criteria.
NHSBSA’s current guidance says an active member normally needs at least two years’ membership, must be under normal pension age, and must be leaving work because ill health prevents them from doing their present job. NHSBSA — ill-health retirement
Tier 1 vs Tier 2 NHS ill-health retirement
| Level | Core test | Broad benefit effect |
|---|---|---|
| Tier 1 | Permanently unable to perform the duties of the NHS job because of ill health | Pension already earned is paid early without the normal early-retirement reduction |
| Tier 2 | Meets Tier 1 and is also permanently incapable of regular employment of similar duration because of ill health | Tier 1 benefits plus an additional enhancement under Scheme rules |
“Permanently” is assessed against the relevant Scheme normal pension age, not simply whether the employee is currently signed off work.
Tier 1
Tier 1 is for a member who is permanently incapable of efficiently carrying out the duties of their NHS employment because of physical or mental ill health.
The pension already earned can be put into payment without an actuarial reduction for taking it early. There is no Tier 1 future-service enhancement.
Tier 2
Tier 2 has a higher test. In addition to qualifying for Tier 1, the member must be permanently incapable of regular employment of like duration to their NHS employment in the general field of employment.
For a 2015 Scheme member, NHSBSA describes Tier 2 as Tier 1 benefits plus an enhancement based on one half of prospective membership to normal pension age. Earlier 1995/2008 benefits have their own rules. NHSBSA — ill-health retirement
Direct answer: Tier 2 is not simply “more severe illness”. The Scheme asks a different work-capability question: whether the member is permanently incapable of regular employment of similar duration, not only their current NHS role.
Can you calculate NHS ill-health retirement online?
You can estimate pension values, but an online tool should not tell a user that they qualify for Tier 1 or Tier 2.
A responsible calculator can model scenarios only after the user supplies an assumed outcome such as:
- “Assume Tier 1 is awarded”; or
- “Assume Tier 2 is awarded”.
The eligibility decision itself requires medical assessment under Scheme rules.
What an estimator can reasonably show
An estimator may help users understand:
- current pension already accrued;
- the effect of paying accrued benefits without ordinary early-retirement reduction;
- an indicative Tier 2 enhancement if sufficient scheme data are available;
- the difference between 1995, 2008 and 2015 benefits;
- why mixed scheme membership requires separate calculations.
What it should not claim
Do not produce:
- a medical eligibility score;
- a percentage chance of approval;
- a guaranteed Tier 2 value from salary and age alone; or
- legal/medical advice about whether someone should leave employment.
Those outputs would imply certainty the Scheme itself does not provide.
Normal pension age matters
The normal pension age differs by Scheme:
- 1995 Section: normally age 60, with some protected Special Class/Mental Health Officer exceptions;
- 2008 Section: age 65;
- 2015 Scheme: State Pension age, or age 65 if later.
This matters because both the meaning of permanent incapacity and the value of some enhancements are tied to normal pension age. NHSBSA — normal pension ages
How the 2015 Scheme pension normally builds up
The 2015 Scheme is a career-average defined-benefit scheme. Each year an active member builds pension equal to 1/54 of that year’s pensionable pay, then the earned pension is revalued while the member remains active. NHSBSA — 2015 Scheme calculation
Ill-health retirement does not turn that into a personal investment pot. A Tier 1 award pays the accrued defined benefit without the ordinary early-payment reduction. Tier 2 can add an enhancement under the rules.
How do you apply for NHS ill-health retirement?
For an active employee, the application normally involves the AW33E process. NHSBSA’s guidance says medical reports should be included and part of the form is completed through occupational-health/medical channels.
Once NHSBSA receives the application it is considered by the Scheme’s independent medical advisers. If successful, the member is awarded Tier 1 or Tier 2 and the pension claim process follows. NHSBSA — ill-health retirement
A practical sequence is:
1. discuss the position with the employer, HR and occupational health;
2. obtain the correct current ill-health application form;
3. provide the relevant medical evidence;
4. allow the Scheme’s medical adviser to assess the criteria;
5. if successful, complete the pension-benefit claim paperwork; and
6. check the award carefully, especially where the decision is Tier 1 rather than Tier 2.
What if you already left the NHS?
A deferred member is in a different position from an active employee.
NHSBSA provides the AW240 route for consideration of early payment of deferred benefits due to ill health. Deferred members do not simply receive the same Tier 2 enhancement as an active member.
Therefore, this page and any calculator should ask first:
Are you an active NHS Pension Scheme member, a deferred member, or already receiving NHS pension benefits?
That question has more semantic value than asking only for age and salary.
Can you appeal a Tier 1 decision?
If a member receives Tier 1 but believes the Tier 2 criteria are met, NHSBSA’s current process allows the member to claim the Tier 1 pension while challenging the decision through the appropriate process.
The page should not advise a user that an appeal will succeed. Instead, direct them to the decision letter, NHSBSA’s dispute/appeal route and, where appropriate, their union or regulated adviser.
What happens if you work again after ill-health retirement?
Returning to work can affect ill-health benefits, especially Tier 2. NHSBSA has specific re-employment rules and in some circumstances a Tier 2 pension can be replaced or affected after a return to employment.
Before accepting new work, a member receiving an ill-health pension should check current NHSBSA re-employment rules rather than assuming the pension will continue unchanged.
Ill-health retirement vs ordinary early retirement
| Ill-health retirement | Voluntary early retirement |
|---|---|
| Requires Scheme ill-health criteria and medical assessment | Member chooses to claim after minimum pension age |
| Tier 1 accrued pension can be paid without normal early-payment reduction | Pension is usually actuarially reduced because it is paid earlier |
| Tier 2 may include enhancement | No ill-health enhancement |
| Eligibility depends on health/work capability | Eligibility primarily depends on age/scheme rules |
If the user is healthy and simply wants to leave work early, send them to the NHS Pension Early Retirement Calculator rather than this page.
Serious ill health and terminal illness
NHS Pension Scheme rules also include a serious-ill-health route where qualifying benefits may be commuted to a lump sum under specific conditions.
This is distinct from an ordinary Tier 1/Tier 2 estimate and should be handled through NHSBSA’s current forms and medical assessment.
Information to collect before requesting an estimate
Have the following available:
- Scheme/section: 1995, 2008, 2015 or mixed membership;
- active or deferred status;
- current age and normal pension age;
- Total Reward/Annual Benefit Statement;
- pension already accrued;
- pensionable earnings;
- any Additional Pension or other purchased benefits;
- any prior retirement/partial-retirement benefits.
A tool should use these to explain the calculation, not merely multiply current salary by years of service.
Key points
- Ill-health retirement eligibility is a medical/Scheme decision, not a calculator result.
- Tier 1 and Tier 2 use different incapacity tests.
- Tier 1 pays accrued pension without the usual early-retirement reduction.
- Tier 2 can add an enhancement.
- 1995, 2008 and 2015 benefits must be treated under their own rules.
- Deferred members follow a different route.
- Returning to work can affect ill-health benefits.
- NHSBSA should be the primary source for forms, eligibility and the final pension award.
Frequently asked questions
How much will I get on NHS ill-health retirement?
It depends on your pension sections, accrued benefits and whether Tier 1 or Tier 2 is awarded. A salary-only calculator cannot provide a reliable final figure.
Is Tier 2 better than Tier 1?
Tier 2 includes an enhancement in addition to Tier 1 benefits, but it has a stricter incapacity test. It is not something a member can simply choose.
Do I need two years in the NHS Pension Scheme?
NHSBSA’s current active-member guidance says at least two years’ membership is normally required for ill-health retirement benefits. Check the current rules for your exact membership circumstances.
Is an ill-health pension reduced because I am under retirement age?
Tier 1 benefits are paid without the ordinary actuarial reduction for early payment. Tier 2 can also include additional enhancement.
Can I take another job after NHS ill-health retirement?
Potentially, but re-employment can affect benefits, especially Tier 2. Check NHSBSA’s re-employment rules before starting work.
