The Working Time Regulations 1998 set legal limits on hours, rest breaks, and annual leave. As an umbrella contractor, these rules apply to you. Your employer must follow them. From April 2026, a new body enforces them.
DASA Umbrella holds dual accreditation from FCSA and Professional Passport.
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 per year. As an umbrella contractor, you're an employee. These rights apply to you in full.
The regulations cover three main areas: maximum weekly hours, rest entitlements, and annual leave. Each has specific 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 per week. This average is calculated over a 17-week reference period. Your employer cannot force you to exceed this average. You can choose to opt out voluntarily, but that's your decision.
The 17-week reference period means short bursts of longer hours don't automatically breach the limit. But the average across those 17 weeks must stay at or below 48 hours.
Working beyond 48 hours regularly without a signed opt-out is a breach. That's reportable.
Night workers get extra protections. They cannot work more than an average of 8 hours per night shift. Health assessments are also a legal requirement 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 sign voluntarily. You can also withdraw it at any time with seven days' written notice, or longer if the agreement specifies.
Signing an opt-out is never compulsory. No one can make it a condition of your engagement. Being told you must sign to get the contract 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 opt-outs as standard even when their work pattern doesn't require one.

What are your rest break entitlements?
You're entitled to a 20-minute rest break if you work more than six hours in a day. You're 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. Finish at 10pm and your next shift cannot start before 9am. That's a legal floor, not a suggestion.
Weekly rest means one full day off per week on average. Some shift workers and sectors have modified rules. The principle stands regardless.
If your engager's working pattern regularly denies you these breaks, that's a legal issue. Keep records of your hours. Your umbrella is your employer and has a duty to act.
What is your holiday entitlement?
Full-time UK workers get 28 days of paid annual leave per year. This includes bank holidays if your employer counts them. As an umbrella employee, 28 days is your entitlement. Part-time workers get a pro-rata amount based on hours worked.
Holiday pay is a separate but connected issue. Your umbrella calculates it based on your average earnings. Rules updated in April 2020 mean variable pay, including overtime, feeds into that calculation.
How your umbrella pays holiday pay varies. Some pay it accrued on each payslip. Others hold it and release it when you request leave. Both are legal if handled correctly.

Who enforces working time regulations for umbrella contractors?
From 7 April 2026, the Fair Work Agency enforces working time regulations for agency workers and umbrella contractors. The FWA replaced the Employment Agency Standards inspectorate. It now handles NMW enforcement, holiday pay, and agency standards under one body. You report violations to the FWA.
Before April 2026, enforcement was split. HMRC handled National Minimum Wage. The Employment Agency Standards inspectorate covered agency worker protections. The Fair Work Agency brought these together into one body.
For umbrella contractors, this is a clear improvement. You now have one place to go if your rights are ignored. The FWA can investigate umbrella companies, agencies, and engagers.
Full holiday pay enforcement is expected to ramp up from 2027. But the FWA is active now and took on complaints from April 2026.

What to do if your rights are being ignored
If your rest breaks are denied, your hours exceed the legal limit without a signed opt-out, or your holiday pay is missing, raise it with your umbrella first. If they don't fix it, report it to the Fair Work Agency. Keep records of hours worked, payslips, and any written communications.
Your umbrella is your employer. They have a duty to make sure your working time rights are respected. If they're the source of the problem, escalate directly to the FWA.
Write down dates and hours worked. Save your payslips. Keep any messages or emails where you raised concerns. The FWA will ask for evidence.
If you work through DASA, contact our team directly. As a dual-accredited umbrella, we take compliance seriously. Our processes are audited by both FCSA and Professional Passport. Read about your full rights in our agency worker rights guide.
