Signed Off Work with Back Pain? What to Do and How It Affects Your Claim

Quick Summary

• If you have back pain caused by a workplace accident, your GP can sign you off work using a fit note — this is one of the most important steps you can take for both your health and your claim
• When you see your GP, clearly explain the workplace cause — the GP record linking your back pain to the accident at work is key evidence for a compensation claim
• While signed off, you are entitled to Statutory Sick Pay (SSP) of £123.25 per week — the difference between this and your normal wage is claimable as lost earnings
• Your employer cannot lawfully dismiss you for making a health and safety complaint or for being genuinely signed off sick following a workplace injury
• Keep every fit note, payslip, and medical letter — all of these support your claim

Can you get signed off work with back pain?

Yes. Back pain is one of the most common reasons GPs issue fit notes in the UK. If your back pain is preventing you from safely carrying out your normal work duties, your GP can sign you off for as long as is medically appropriate.

You do not need to prove that your employer was at fault to get signed off. Your GP assesses your current ability to work based on your symptoms, not the legal cause of the injury. The fit note simply confirms that you are not fit for your current job role during the period covered.

If your back pain was caused by a workplace accident, being properly signed off from the outset protects both your health and your right to claim compensation. For the full picture of your rights after a back injury, see our back injury claims guide.

How do you get a sick note for back pain from your GP?

Contact your GP practice as soon as you are unable to work. If you cannot get an appointment quickly, you can also be assessed via telephone or video consultation. In urgent cases, NHS 111 can direct you to appropriate care.

At the appointment, describe your symptoms honestly and in full:

• The location and severity of the pain
• Whether it radiates to your legs, hips, or buttocks
• What movements or activities you cannot perform
• Whether you are sleeping, sitting, standing, or walking normally
• Any medication you are taking for the pain

Your GP will assess you clinically and, if they agree you are not fit for work, will issue a fit note (officially called a Statement of Fitness for Work). This replaces the old sick note and can either state you are "not fit for work" or "may be fit for work" with modifications. For a significant back injury, "not fit for work" is the appropriate status until you have recovered sufficiently.

Fit notes can cover any period from a few days to several months. Your GP will specify the duration and you can return for a renewal if the injury persists.

What should the sick note say if your back pain was caused at work?

This is the single most important step injured workers frequently miss. When you see your GP about back pain caused by a workplace accident, tell them clearly:

• The date of the accident
• How the injury happened (a fall, a manual handling incident, a machinery accident)
• That it occurred at work

The GP's clinical notes will record what you tell them about the cause. This creates a contemporaneous medical record linking your back pain to a specific workplace incident. That record becomes a key piece of evidence if you make a compensation claim, because it establishes the causal connection from the earliest possible date.

If your GP records say only "back pain" without noting the workplace cause, your solicitor will still be able to obtain the records and may be able to establish the link through other evidence. But a clear causal note from day one is far stronger.

Do not exaggerate your symptoms. Describe them honestly and let the clinical record reflect the truth.

What are your sick pay rights while signed off with back pain?

While you are signed off, you are entitled to Statutory Sick Pay (SSP) of £123.25 per week for up to 28 weeks, paid by your employer. SSP begins from the fourth day of absence. The first three days are unpaid waiting days unless your employment contract provides otherwise.

Your contract may entitle you to enhanced or full pay for a period. Check your contract or staff handbook. Your employer cannot pay you less than SSP, but they may choose to pay more.

The difference between your normal wage and what you actually receive during your sick leave is recoverable as lost earnings in a compensation claim. If you earn £500 per week and receive only SSP of £123.25, the shortfall of £376.75 per week is claimable for every week you were off work due to the injury.

For a full explanation of how sick pay and compensation interact, see our full pay guide.

How does being signed off affect your compensation claim?

Being properly signed off with a fit note creates several important pieces of evidence that directly support a back injury compensation claim.

The fit note itself confirms that you were medically assessed as unfit for work during a specific period. This proves your absence was genuine and medical in origin, not voluntary.

The GP's clinical notes record the symptoms, the cause (if you mentioned the workplace accident), any referrals made, and the treatment prescribed. Your solicitor will request these as part of the investigation.

Your payslips during the period show what you actually received. The difference between normal earnings and sick pay is your claimable loss of earnings.

The length of absence indicates the severity of the injury in a way that supports the general damages valuation. A minor back strain that resolves in two weeks is valued very differently from a disc injury that keeps a worker off for six months.

One important point: do not return to work before you are medically ready just because you feel financial pressure. An early return that proves unsustainable can complicate the claim. Let your GP guide the return-to-work decision and document any phased return or modified duties arrangement in writing.

Your general rights while signed off are covered in our injured at work rights guide.

What to do after being signed off with a work back injury

Keep every fit note your GP issues. Do not throw them away.

Keep payslips covering every week you are off work. If your pay reduces during the absence, keep all records showing both what you normally earn and what you received.

Notify your employer of your absence in writing and request that the original accident is recorded in the accident book if this has not already been done.

Ask your GP to refer you for physiotherapy or specialist assessment if your symptoms are not improving. Active treatment supports a better medical outcome and demonstrates that you are taking the injury seriously.

When you are ready, speak to a specialist solicitor. A back injury claim can recover every week of lost earnings, medical costs, and the compensation for the injury itself, handled on a no win no fee basis.

Frequently asked questions

How long can you be signed off work with back pain?

There is no fixed maximum period. Your GP will issue fit notes for as long as they assess you as unfit for work. SSP is available for up to 28 weeks. After that, if you remain unable to work, you may be eligible for Universal Credit or Employment and Support Allowance while your compensation claim is ongoing. A solicitor can also apply for interim payments in serious cases.

Do I have to tell my employer the back pain was caused at work?

You do not have to give your employer detailed medical information, but you should report the original accident to them and ensure it is recorded in the accident book. If the accident has already been reported, your employer is aware of the connection. Keeping the link clear from the outset protects both your claim and your employment rights.

Can I be dismissed while signed off sick with a back injury from work?

Dismissing an employee for making a health and safety complaint or for a workplace accident claim is automatically unfair under the Employment Rights Act 1996, with no qualifying period. Dismissing an employee on long-term sick leave may be permissible in limited circumstances, but only if handled correctly. Dismissal while you are signed off following a workplace injury is a serious risk for any employer and should be reported immediately to a solicitor.

What happens to my pay after 28 weeks of SSP?

SSP ends after 28 weeks. If you remain unable to work, you may be eligible for Universal Credit or Employment and Support Allowance. Separately, your compensation claim can include an ongoing loss of earnings element even after SSP ends. In serious cases where settlement is some time away, a solicitor may seek interim payments to cover your financial needs while the claim is resolved.
