You Are Configuring It Yourself, So Know What You Are Configuring To

BambooHR will track UK holiday and absence perfectly well. It will not do it for you — the defaults are American, and every UK rule is something you build.

Which makes the rules themselves the important part of this article, and two of them have changed recently enough that most guidance still has the old version. Statutory sick pay no longer has waiting days. And the holiday calculation for irregular-hours workers reverted to a percentage method that earlier case law had ruled out.

Get those wrong in the configuration and the system will faithfully apply your mistake to everyone.

UK Statutory Holiday: The Current Rules

The Entitlement, and the Cap

Under the Working Time Regulations 1998, almost all UK workers get 5.6 weeks of paid annual leave a year. For someone working five days a week that is 28 days.

The cap matters and is often left out: 5.6 weeks is capped at 28 days, however many days a week someone works. A six-day-a-week employee is entitled to 28 days, not 33.6. If you build a policy that multiplies days worked by 5.6 without a ceiling, it will over-grant.

Whether bank holidays sit inside or on top of that is the employer’s choice, provided the total meets the minimum.

Part-Time, Pro Rata and Rounding

Multiply contracted days per week by 5.6. Three days a week gives 16.8 days.

On rounding, the rule is more specific than usually reported:

• You can never round down below the calculated entitlement
• In the first year of employment, you must round part days up to the nearest half day
• After the first year, rounding up is optional — you may, but you are not obliged to

So “always round up to the nearest half day” is right for year one and overstates it thereafter.

Bank Holidays Vary by Nation

England and Wales have eight, Scotland has nine and Northern Ireland has ten. If you employ across borders, that is three different calendars, and no HR system will infer it for you.

Irregular Hours and Part-Year Workers: 12.07%

The position most guidance still gets wrong.

Harpur Trust v Brazel (Supreme Court, 2022) ruled out pro-rating holiday for permanent part-year workers, which took the long-used 12.07% method off the table for them. The 2024 reforms reversed that.

For irregular-hours and part-year workers:

• Holiday accrues at 12.07% of hours worked in each pay period
• This applies to leave years beginning on or after 1 April 2024 — the regulations commenced on 1 January 2024, but the holiday changes only bite from the first leave year starting on or after April
• Rolled-up holiday pay is permitted for these workers, calculated on total earnings in the period. It was previously unlawful.
• Workers on regular hours are unaffected

If you use rolled-up holiday pay for casual staff, your system needs to reflect that rather than accruing days.

How BambooHR Models Time-Off Policies

The time-off module is genuinely flexible, which is its strength and the reason the configuration burden falls on you.

Under Settings, you build Time-Off Policies defining:

• Policy name
• Accrual type — lump sum at the start of the year, per pay period, or per hour worked
• Accrual amount and frequency
• Maximum balance, for carryover limits
• Whether negative balances are allowed, which is useful in a first year
• Who it applies to, by location, department or employment type

For a standard full-time UK employee on 28 days, a lump-sum policy granting 28 days at the start of the holiday year works cleanly, pro-rated from the start date where needed.

New starters can be pro-rated automatically based on start date within the leave year, which removes a real source of manual error — though remember the first-year rounding rule above.

Carryover limits are configurable, including zero. There is no statutory right to carry leave over unless it could not be taken — through sickness or family leave, for instance — so this is a policy judgement you make and the system enforces.

The accrual type worth knowing about: per-hour accrual is how you implement 12.07% for irregular-hours staff, rather than trying to express it in days.

Bank Holidays: Manual Either Way

BambooHR has no built-in UK public holiday calendar. Two approaches, neither seamless.

If bank holidays are inside the entitlement — 28 days inclusive — you configure nothing special. People book bank holidays as ordinary leave.

If they sit on top — 20 days plus 8 bank holidays — create a separate Bank Holiday time-off type and either add dates to calendars individually or upload them in bulk. Many teams pre-populate the year’s bank holidays for everyone each January.

With staff in Scotland or Northern Ireland you are maintaining separate calendars by hand, because the system will not flag the regional differences.

Part-Time and Pro-Rata in Practice

BambooHR handles part-timers, deliberately rather than automatically. Options:

• A policy per working pattern — one for three-day-a-week staff at 16.8 days, another for four-day staff, and so on
• Individual overrides, setting entitlement per employee against the default policy

It will not calculate 5.6 × contracted days for you. You do that arithmetic, apply the 28-day cap, handle the rounding, and enter the result.

The workaround worth adopting early: track leave in hours rather than days. Pro-rata becomes arithmetic rather than a policy per pattern, and it is what Acas suggests for varied working patterns. BambooHR supports hours-based tracking, but you have to set the policies up that way from the start — converting later is painful.

Absence Beyond Annual Leave

Sickness, and the SSP Rules That Changed

BambooHR tracks sickness well. Create a Sickness time-off type, log days, and run absence pattern reports — useful for return-to-work conversations and spotting trends.

It does not calculate statutory sick pay, which is a payroll function. But what you are recording feeds payroll, so the current rules matter:

Since 6 April 2026:

• SSP is payable from day one of sickness. The three waiting days have been abolished.
• The lower earnings limit has been removed — all eligible employees qualify regardless of earnings
• Those earning below the former threshold receive 80% of weekly earnings
• The rate for 2026/27 is £123.25 a week

Any configuration, handbook or process still built around a three-day waiting period is out of date, and so is any reference to £116.75. If your absence recording was set up to flag sickness only from day four, it now needs to capture day one.

Family Leave, Including One Most Lists Miss

Create custom time-off types for maternity, paternity, shared parental and adoption leave. BambooHR records the dates; payroll calculates SMP and the rest.

Two additions to the usual list:

Neonatal Care Leave has been a statutory right since 6 April 2025 and is routinely left out. Eligible parents get up to 12 weeks, one week for each full uninterrupted week their baby spends in neonatal care, where that care starts before the baby is 28 days old and lasts at least seven days. It must be taken within 68 weeks of birth and sits on top of maternity or paternity leave. It is a day-one right. Statutory Neonatal Care Pay has its own conditions, including 26 weeks’ continuous service, so leave and pay can diverge — check the current rate with payroll.

Parental leave became a day-one right on 6 April 2026, alongside changes to paternity leave. If your policy still applies a qualifying period, it needs updating.

Parental bereavement leave has been a statutory right since 2020.

Everything Else

Custom absence categories are unlimited — compassionate leave, jury service, unpaid leave, study leave, medical appointments. This flexibility is a genuine strength for UK employers who need more than the basics, and it is where BambooHR earns its keep on the absence side.

Approval Workflows

Solid, and the part that needs no caveats. Employees request leave through self-service on desktop or mobile, requests route to a manager, managers approve or decline from email or in-platform, and employees are notified automatically.

Configurable: who approves, whether a leave type needs approval at all, and shared leave calendars so the team can see who is off. That visibility is where small businesses get the most day-to-day value, because cover planning is the actual problem.

What It Will Not Do

• No UK public holiday calendar, and no awareness of regional variation
• No automatic 5.6-week calculation or 28-day cap
• No SSP, SMP or statutory pay calculation — all payroll
• No HMRC or RTI connection. BambooHR is the HR layer; payroll sits elsewhere, and our payroll comparison covers the options
• No warning if you configure something wrong. It applies what you tell it

FAQ

Does BambooHR calculate UK statutory holiday automatically?

No. It gives you the policy tools; you supply the 5.6-week calculation, the 28-day cap, the pro-rata arithmetic and the rounding. It does not apply the Working Time Regulations natively.

Can it handle Scottish and Northern Irish bank holidays separately?

Not automatically. Scotland has nine bank holidays and Northern Ireland ten against England and Wales’ eight, and you maintain those calendars manually.

How should I set up holiday for zero-hours or term-time staff?

Use per-hour accrual at 12.07% of hours worked, for leave years beginning on or after 1 April 2024. Rolled-up holiday pay is now permitted for these workers, so decide which approach you are using before building the policy.

Does it calculate statutory sick pay?

No, that is payroll. Note that SSP has been payable from day one since 6 April 2026 at £123.25 a week, with no lower earnings limit — so any absence process built around a three-day wait needs revisiting.

Do I need to track Neonatal Care Leave?

Yes, if it applies. It has been a statutory day-one right since 6 April 2025, giving up to 12 weeks on top of other family leave. Create a custom time-off type for it; most leave-type lists omit it.

Is BambooHR worth it for a small UK business?

Cost is the deciding factor, and it is not per-employee at small sizes. BambooHR charges a flat monthly fee for companies with 25 or fewer employees — roughly £200 a month whether you have four staff or twenty-four. For holiday and absence tracking alone that is hard to justify below about fifteen people, and our BambooHR alternatives comparison sets out what the same money buys elsewhere.

Which UK-native tools handle this better out of the box?

Breathe HR and Charlie HR both build UK holiday rules in as defaults rather than configuration. See our Breathe HR review and Charlie HR and BambooHR comparison.

The Bottom Line

BambooHR’s time-off module is capable, flexible and perfectly usable for UK teams. What it is not is UK-aware. Every rule in the first half of this article is something you configure, and the system will apply your configuration faithfully whether or not it is right.

So the work is knowing the rules before you build. 5.6 weeks capped at 28 days. Round up in the first year, never round down. 12.07% for irregular hours, with rolled-up pay now permitted. SSP from day one at £123.25, with waiting days gone. And Neonatal Care Leave as a day-one right alongside the family leave types everyone remembers.

If BambooHR is already in the frame for onboarding, records and performance, the absence module will serve you well. If holiday tracking is the main thing you are buying, a UK-native tool will get you there with far less configuration — and, at a flat £200 a month below 26 employees, for considerably less money. Our buying checklist covers what else to settle before committing.
