According to gov.uk, employees can self-certify sickness for the first seven calendar days, so most routine GP visits don't require a fit note. Employers still expect clear notice, evidence when necessary and a practical plan for cover. This guide explains, step by step, how to write a leave application for a doctor's appointment in the UK in 2026, what proof may be required, and how to keep the process painless for you and your manager.

Quick reference

Use this checklist before you write:

  • Self-certify absences up to 7 calendar days, you usually won’t need a GP note. According to gov.uk, employees can self-certify for the first 7 days of sickness.
  • From day 8 onwards an employer can ask for a fit note (Statement of Fitness for Work). Get details at https://www.gov.uk/get-a-fit-note.
  • NHS GP consultations are free to registered patients; private GP appointments typically cost between £40 and £120 in 2026.
  • If you’ll claim Statutory Sick Pay (SSP) or contractual sick pay, check rules and current rates at https://www.gov.uk/statutory-sick-pay, eligibility depends on earnings and length of service.
  • Give as much notice as possible. For routine appointments, 24-48 hours is a reasonable standard; for hospital outpatient referrals or procedures, provide the full clinic date as soon as you have it.

Prerequisites, what to check before you write

First, read your employment contract, staff handbook or intranet. Employers set internal rules about notice, whether you must use annual leave for routine care and how evidence should be supplied. Many employers accept an emailed appointment confirmation or a screenshot from the GP practice. If in doubt, follow the formal route your employer specifies.

Second, know whether the appointment will be NHS or private. NHS GP appointments and NHS outpatient appointments are provided without charge to eligible residents; private consultations cost extra, typical 2026 fees range from about £40 to £120 for a single private GP visit. If you book privately and intend to reclaim costs under a company health scheme, check the scheme rules in advance.

Third, understand sick-pay rules. Statutory Sick Pay is paid through employers provided you meet the earnings threshold and other criteria, see https://www.gov.uk/statutory-sick-pay. Employers may offer contractual sick pay that’s more generous. If you expect to be off for more than seven calendar days, plan to obtain a fit note from day 8 onwards; employers can also ask for occupational health advice for longer absences.

Step-by-step: how to write the leave application

  1. Step 1. Choose the right format

    Is email acceptable? Most workplaces prefer email for routine requests. Use a formal letter only if your employer asks for hardcopy. For schools, universities or small organisations, follow the published absence process: some use online portals or HR systems.

  2. Make the purpose obvious at a glance. Examples: "Request: Time off for GP appointment, 7 June 2026" or "Sick leave: outpatient appointment 21 July 2026 (am)". A short, precise subject helps managers triage cover quickly.

  3. Say the exact date, start time and approximate length you’ll be away. Employers need to know when you’ll be unavailable. Example: "I have a GP appointment on 7 June 2026 at 09:30. I expect to be away from my desk from 09:15 until 11:00." If travel or parking will add time, include it.

  4. Basically, explain who will handle urgent tasks or how you’ll hand over. That reduces friction. For instance: "I’ll finish the client brief by 17:00 on 6 June and ask Sam to cover urgent queries between 09:00-11:30 on 7 June. I’ll be reachable by mobile for emergencies." Offer a single contact for urgent matters.

  5. Be explicit. Employers need to process payroll and keep records. Write: "This absence is for a medical appointment; I don't expect to claim SSP for under-7-day absences" or "I will submit a fit note if absence continues beyond seven days." If you prefer to take paid annual leave, say so.

  6. Many employers accept an emailed appointment confirmation or screenshot. If the appointment is for day 8+ sick leave, plan to supply a fit note from your GP or hospital clinician. For private appointments employers may ask for the booking confirmation or receipt, check your company policy. Keep the original so you can forward it if asked.

  7. Don’t overshare medical details. State the necessity and practicalities. Example sentence: "I have an outpatient appointment regarding a long-term condition and will be off-site from 13:00-15:30; I’ll update you if that changes and can supply confirmation if needed." That’s enough.

  8. Confirm you’ve returned to work or provide a fit note if absence continues. Send a short update: "Back in the office today, thanks for covering. I’ve attached the appointment confirmation as requested." That closes the loop and helps HR records.

Below are two practical templates you can copy into an email. They’re written as finished examples rather than placeholders.

Template 1. Routine GP appointment (email)

Subject: Request for time off. GP appointment 12 August 2026 (09:30-11:30)

Hello Hannah,

I have a GP appointment on 12 August 2026 at 09:30 and expect to be off-site from 09:15 until 11:30. I’ll complete the incoming client emails by 17:00 on 11 August and have asked Amir to cover urgent queries while I’m out. But i’ll be available by phone if needed.

I don’t expect to claim SSP for this short absence but can provide the appointment confirmation if required.

Thanks,
Alex

Template 2. Sick leave leading to hospital appointment (email)

Subject: Sick leave & appointment, outpatient clinic 3 September 2026

Hi James,

I’m reporting sick today and have an outpatient appointment at 14:00 on 3 September 2026. I expect to be away for the afternoon and will update you if this becomes a longer absence. If I’m still off after seven calendar days I’ll arrange a fit note from my GP or hospital clinician.

I’ve shared my calendar with Sarah so she can manage any urgent meetings.

Regards,
Maya
  • Notify your manager and HR separately if your employer requires both. Don’t assume one message covers all channels.
  • Keep records, save appointment emails, screenshots and any fit notes in a secure place. Employers may ask to see them for payroll or absence tracking.
  • If you need recurring treatment (physio, mental health sessions) agree a standing arrangement with your manager to avoid repeated formal requests.
  • Use NHS e-Referral Service confirmations or private clinic receipts as evidence. Many employers accept these as proof.
  • If travel will delay your return, include travel time in your request, commuting delays are often accepted as part of the appointment window.
  • Being vague about time away, write start and end times.
  • Oversharing sensitive medical details, state the condition only if it affects work and you’re comfortable doing so.
  • Failing to follow company process for evidence, check the staff handbook before forwarding documents.
  • Assuming your manager knows your schedule, always state the date and time in the message subject and body.
  • Delaying a follow-up, if absence extends, inform your employer promptly and supply a fit note from day 8 if requested.

A concise, polite leave application usually does the job: state the date and time, how long you'll be away, how work will be covered, and whether you can supply evidence. Keep records, follow your employer’s written rules, and if absence continues beyond seven calendar days arrange a fit note. Clear communication saves time, and keeps payroll and HR onside.
