What sort of letter is this?
A letter describing the practical, functional impact of a condition — for workplace adjustments, exam access arrangements, venue and attraction access schemes, or housing and adaptation requests.
Tell us which, and send the form or criteria. They ask for different things.
Why does the letter focus on function rather than my diagnosis?
Because that is what the recipient acts on. "Has fibromyalgia" gives an employer nothing to do. "Cannot sit for more than 40 minutes without needing to stand; fatigue is worst in the afternoon; would benefit from a sit-stand desk and flexible break timing" is actionable.
The second letter gets adjustments. The first gets filed.
Will my employer have to do what it says?
They have to consider it seriously and make reasonable adjustments where a disability puts you at a substantial disadvantage — they are not obliged to grant every specific request.
What is "reasonable" depends on cost, practicality and the size of the organisation. A refusal must have a proper reason, and you are entitled to it in writing.
Am I disabled under the Equality Act?
The definition is broader than most people assume: a physical or mental impairment with a substantial, long-term (twelve months or more) adverse effect on normal day-to-day activities.
Fluctuating and recurring conditions count. Conditions controlled by medication count — the test is the effect without the treatment. Cancer, HIV and multiple sclerosis are covered from the point of diagnosis.
You do not need a formal "disabled" label to ask for adjustments, and many people who qualify have never thought of themselves that way.
Is a GP letter enough, or do I need occupational health?
For straightforward requests a GP letter is usually enough. For anything complex or contested, occupational health carries more weight — it assesses you against your actual job and makes recommendations directly to the employer.
Your employer arranges and pays for OH. A GP letter is often what prompts that referral rather than a substitute for it.
Can you diagnose ADHD or autism for an exam access application?
No — those require a specialist assessment, and universities and awarding bodies generally require a report from a specialist or an educational psychologist.
What we can do is describe functional impact, write about a diagnosis you already hold if you bring the documentation, and refer you for assessment.
Can you complete a PIP or ESA form?
No. Those specifically require your registered NHS GP or DWP's own assessment process, and a private letter is not accepted.
Free specialist help exists and is much better than a GP letter for this: Citizens Advice, and disability advice services who do this daily.
Will you say my condition is worse than it is?
No. The letter records what the assessment establishes.
That is in your interest: an overstated letter is recognisable, and it undermines everything else in the application. A precise account of what you genuinely cannot do is more persuasive and it survives scrutiny.
Should I be applying for Access to Work?
Almost certainly yes, and hardly anyone does. It is a government grant covering equipment, support workers and travel to work, it is not means-tested, and it pays the employer's cost rather than yours — which removes the commonest objection to an adjustment.
Apply on GOV.UK. Waits are long, so start now.
Do I have to tell my employer my diagnosis?
No. You are entitled to ask for adjustments without disclosing the condition itself, and a letter can describe functional impact and recommend adjustments without naming a diagnosis.
Tell us if you would prefer that. Disclosure sometimes strengthens a case, particularly for Equality Act protection — and it is entirely your decision, not ours.
