The Working Time Regulations 1998 set the legal limits on working hours, rest breaks and annual leave. If you work through an umbrella company, they apply to you. Your employer has to follow them. From 2027, the Fair Work Agency is expected to enforce the holiday rights.
A UK umbrella company should hold accreditation from FCSA, Professional Passport and SafeRec.
What are the working time regulations?
The Working Time Regulations 1998 give UK workers the right to a maximum 48-hour working week, daily and weekly rest breaks, and 28 days of paid annual leave each year. As an umbrella contractor, you are an employee. These rights apply to you in full.
The rules cover three areas: maximum weekly hours, rest entitlements and annual leave. Each area has its own rules. Employers cannot ask you to waive most of these rights. The 48-hour limit is the main exception.
These rules apply regardless of your sector or how long your contract runs.
How many hours can you work each week?
The working time regulations set a maximum average of 48 hours a week. That average is worked out over a 17-week reference period. Your employer cannot force you to go over it. You can opt out voluntarily, but that has to be your choice.
Short bursts of longer hours do not automatically breach the limit. The average across the full 17 weeks still has to stay at or below 48 hours.
If you regularly work beyond 48 hours without a signed opt-out, that is a breach and can be reported.
Night workers get extra protections. They cannot work more than an average of 8 hours a night. Health assessments are also required for night workers.
What is the 48-hour opt-out?
The 48-hour opt-out lets you agree in writing to work beyond the weekly average. Your umbrella or engager may ask you to sign one. You can do that voluntarily. You can also withdraw it at any time with seven days’ written notice, or longer if the agreement says so.
Signing an opt-out is never compulsory. No one can make it a condition of your engagement. If you are told you must sign one to get the contract, that is a breach of your rights.
Check whether your umbrella contract includes an opt-out clause. If it does, check whether you actually need it for your role. Many contractors sign one by default, even when their working pattern does not need it.

What are your rest break entitlements?
If you work more than six hours in a day, you are entitled to a 20-minute rest break. You are also entitled to 11 consecutive hours of rest between working days. You get at least 24 hours of uninterrupted rest each week, or 48 hours each fortnight.
These are minimum entitlements. Your contract can give you more. It cannot give you less.
Daily rest means 11 hours between finishing work and starting again. If you finish at 10pm, you cannot start again before 9am. That is the legal minimum.
Weekly rest means one full day off each week on average. Some night workers and sectors have modified rules, but the basic entitlement still stands.
If your engager’s working pattern regularly denies you these breaks, that is a legal issue. Keep records of your hours. Your umbrella is your employer, and it has a duty to act.
What is your holiday entitlement?
Full-time UK workers get 28 days of paid annual leave a year. That can include bank holidays if your employer counts them that way. As an umbrella employee, 28 days is your entitlement. Part-time workers get a pro-rata amount based on hours worked.
Holiday pay is separate, but it is linked. Your umbrella calculates it from your average earnings. Rules updated in April 2020 mean variable pay, including overtime, counts in that calculation.
How your umbrella pays holiday pay varies. Some pay it as it accrues on each payslip. Others hold it back and release it when you take leave. Both are legal if they are handled correctly.

Who enforces working time regulations for umbrella contractors?
The Health and Safety Executive enforces the weekly limit, with other regulators in some workplaces. From 2027, the Fair Work Agency is expected to enforce holiday rights. It took over from the Employment Agency Standards inspectorate. HMRC delivers NMW enforcement for it until April 2027.
Before April 2026, enforcement was split. HMRC handled National Minimum Wage. The Employment Agency Standards inspectorate covered agency worker protections. The Fair Work Agency now oversees both.
For umbrella contractors, this makes things simpler. The FWA is bringing NMW and agency standards enforcement together. The FWA can investigate umbrella companies, agencies and engagers.
Holiday pay enforcement is expected from 2027. The FWA is already active on NMW and agency standards.

What to do if your rights are being ignored
If your rest breaks are denied, your hours go over the legal limit without a signed opt-out, or your holiday pay is missing, raise it with your umbrella first. If that does not fix it, contact Acas for advice. Keep records of hours worked, payslips and any written messages.
Your umbrella is your employer. It has a duty to make sure your working time rights are respected. If it is the problem, contact Acas for advice.
Write down dates and hours worked. Save your payslips. Keep any messages or emails where you raised concerns. You will need this evidence if you make a claim.
If you work through DASA, contact our team directly. We take compliance seriously, and FCSA, Professional Passport and SafeRec all check our processes. Read about your full rights in our agency worker rights under AWR.
