Being off work injured almost always means being financially worse off. Two separate things are going on at the same time, and it is worth pulling them apart clearly, because they are handled through different routes and different sets of rules.
The first is the pay you receive from your employer while you are off sick — Statutory Sick Pay (SSP) or contractual sick pay under your contract of employment. The second is the shortfall between what you actually receive and what you would have earned but for the injury — the difference between your normal wages and the sick pay you end up on. Those two things are treated very differently in the system, and both may be relevant to your situation.
Sick pay while you are off work
While you are unable to work because of your injury, the money you receive from your employer normally falls into one (or both) of these categories:
- Statutory Sick Pay (SSP). This is the legal minimum an eligible employee is entitled to when unable to work due to illness or injury. It is paid by your employer, at a set weekly rate set by legislation, and it is time-limited — SSP does not continue indefinitely.
- Contractual sick pay. Some employers provide a more generous sick pay scheme through the contract of employment. Where that applies, contractual sick pay usually pays a higher amount than SSP for a defined period (for example, full pay for a set number of weeks followed by half pay, or some similar structure). Whether you are entitled to it, and on what terms, depends entirely on what your contract of employment says.
If your contract does not include a sick pay scheme, SSP is your baseline entitlement. See the general guide on pay while injured at work for how this typically plays out.
Because SSP is well below normal wages for most workers, and contractual sick pay usually tapers over time, the practical effect of being signed off with a serious workplace injury is a significant and continuing drop in income.
The lost earnings you are entitled to claim
This is where a personal injury claim comes in — and where the second, separate route starts.
Whatever your employer legitimately pays you while you are off sick, there is almost always a shortfall between your normal pay and the sick pay you end up receiving. That shortfall is the loss caused by the accident. In legal terms, it is a "special damage" — a specific, quantifiable financial loss suffered as a result of someone else's negligence.
If your injury was caused by an employer's breach of duty, that shortfall is recoverable as part of your compensation claim. That means:
- The full value of your normal pre-accident earnings, including elements like regular overtime and shift premiums that you would have worked, is used as the baseline.
- The actual pay you received during your absence (SSP, contractual sick pay, or both) is deducted.
- The difference is claimed back from the negligent party — in practice, from the employer's liability insurer.
For claimants still off work at the point of settlement, or expected to be affected in the longer term, future loss of earnings is calculated separately and forms its own head of loss, on top of the past losses already accrued.
What you should keep
Because past lost earnings are proved by documents rather than by memory, keeping the paperwork is essential. Useful evidence includes:
- Payslips from before the accident showing your normal pay, including overtime, shift work and bonuses.
- Payslips during your absence showing what you actually received (SSP, contractual sick pay, or nothing).
- Payslips from after you returned to work if you have gone back on reduced hours or lighter duties.
- Fit notes and correspondence with the employer confirming the periods you were signed off.
- Contract of employment and any staff handbook or sick pay policy to show what you were contractually entitled to.
Where possible, keep the original electronic copies. Insurers routinely question the earnings baseline, and a claim supported by full payslip evidence is much harder to argue down than one built on estimates.
Where wages are wrongfully withheld
Everything above assumes that your employer is paying you what they are properly obliged to pay — which, for most people, is either SSP or the applicable contractual sick pay. Sometimes, though, an employer withholds pay you are actually owed. That is a different problem.
For example:
- You worked hours before the accident and have not been paid for them.
- SSP is not being paid despite you meeting the eligibility conditions.
- Contractual sick pay is being withheld despite your contract clearly entitling you to it.
- Deductions are being made from your pay without proper authorisation.
These are usually unlawful deductions of wages — an employment law issue rather than a personal injury issue. That is a separate matter from the injury claim, dealt with through the employment tribunal system or the courts, with its own rules and time limits. It runs in parallel to the injury claim, not through it.
In practice, most people affected by a workplace accident have one problem, not both. Either their employer is paying the correct sick pay and the issue is simply the shortfall from normal wages (which is the personal injury claim's job to recover), or the employer is not paying properly and there is a separate employment-law problem to address. Understanding which situation applies is the first step in getting the right advice for each.
How the two routes fit together
A well-run workplace injury claim will:
- Reclaim the full shortfall between your normal pre-accident pay and the sick pay you have received, for every week you have been affected — that is what special damages are for.
- Project future losses of earnings forward if the injury is likely to affect your capacity to work beyond settlement.
- Take into account any repayment obligations under the Compensation Recovery Unit rules where you have received state benefits during your absence.
- Leave the separate question of unpaid contractual wages, if there is one, to be dealt with through employment law channels.
The financial effect of a serious workplace injury is rarely just about the injury itself. Wages, sick pay and lost earnings sit at the centre of most claims, and getting the paperwork right early makes a real difference to what can be recovered at the end.
Related questions
Can I claim the difference between my normal salary and SSP?
Yes. The difference between your contractual wages and the SSP you received is a recoverable loss of earnings in your personal injury claim against the employer responsible for your accident.
What if my employer has stopped paying me SSP?
If you are eligible for SSP and your employer is refusing to pay it, you can ask HMRC to adjudicate using form SSP1. You may also have an unlawful deduction of wages claim.
