Key UK HR dates for your calendar in 2025

January 7, 2025

A new year has come around once again, and as the celebrations of the past few weeks die down, many are returning to work and getting back into the swing of routine.

For HR professionals, it’s the time to plan for important HR-related moments in the year ahead – including national/international celebrations to acknowledge and Bank Holidays to remember when processing employee absences.

In this blog post, we highlight the key 2025 HR dates in the UK for you to note in your calendar.

Wednesday 1st January 2025 – New Year’s Day

Bank Holiday

Monday 20th January 2025 – Brew Monday

Many of us are familiar with the term ‘Blue Monday’ as the most depressing day of the year. Flipping this negativity on its head, the charity Samaritans have – for the past few years – pushed an initiative to rename the third Monday in January to ‘Brew Monday’.

The idea is to get as many people as possible to reach out and connect with family, friends, or loved ones over a good old cuppa. Organisations can get involved by hosting Brew Monday events for employees either in the office or virtually.

Tuesday 1st April 2025 – National Wage changes

Every year, the National Minimum and Living Wage changes (announced in the Autumn Statement) come into effect at the start of April. From this date, the rates will increase as follows:

To 31 March 2025From 1 April 2025Percentage increase
National Living Wage (21 and over)£11.44£12.216.7%
18-20 Year Old Rate£8.60£1016.3%
16-17 Year Old Rate£6.40£7.5518%
Apprentice Rate£6.40£7.5518%
Accommodation Offset£9.99£10.666.7%

 

Saturday 5th April 2025 – Payroll year-end

For HR professionals who process payrolls, 5th April each year marks the end of the financial year and on 6th April, we move from tax year 2024/25 into 2025/26. By this date, all employee payroll records must be updated (including reporting your final FPS report of the year to HMRC) with P60s processed, before updating your payroll software – opening month 1/week 1 of the new tax year ready for the next pay period.

Sunday 6th April 2025 – National Insurance and Employment Allowance Changes

As announced back in October’s Autumn Budget, from 6th April 2025, the main rate of employer’s National Insurance contributions (NICs) will increase from 13.8% to 15%. The current employee NI rates (8%) will remain in place. Also from this date, the Secondary Threshold (the employee earnings amount at which employers start to pay NI contributions) will be lowered from £9,100 per year to £5,000 per year.

Finally, also from 6th April 2025, the employment allowance will be increased from £5,000 to £10,500 per year and the existing eligibility threshold will be removed completely.

Monday 12th – Sunday 18th May 2025 – Mental Health Awareness Week

With employee health and wellbeing being high on the priority list for many organisations in recent years, Mental Health Awareness Week is a campaign to get involved in. An initiative from the Mental Health Foundation, the week aims to tackle the stigma around mental health and encourages us all to create a society that prevents mental health problems from developing.

The theme for 2025 is yet to be announced, but businesses can support the cause by taking on sports challenges, holding group discussions around mental health experiences, fundraising for the Foundation, or simply donating.

Monday 26th May 2025 – Spring Bank Holiday

June 2025 – Pride Month

Diversity, equity, and inclusion (DEI) is another topic ranking high on business leader’s agendas in recent times. As such, Pride Month is another celebration to note. Running throughout June each year, the movement honours the LGBTQ+ community, their history, achievements, rights, and advocacy.

Organisations can show their support by hosting company-wide events, participating in pride parades, demonstrating how they’re working to create a more inclusive workplace, or volunteering with local groups that support LGBTQ+ youths.

Sunday 6th July 2025 – Deadline for filing P11Ds

For employers who process benefits in kind (any taxable items employees receive in addition to their salary), the P11D form used to report those items must always be sent to HMRC by 6th July.

Monday 25th August 2025 – Summer Bank Holiday

Bank Holiday

Monday 1st – Friday 5th September 2025 – National Payroll Week

Payroll teams are the unsung heroes in many organisations – they’re never usually acknowledged until something goes wrong! National Payroll Week is a chance to recognise and celebrate the wonderful teams who keep employees paid month after month, or week after week, organised by the Chartered Institute of Payroll Professionals (CIPP).

Monday 15th – Sunday 21st September 2025 – National Inclusion Week

Continuing with the importance of diversity, equity, and inclusion (DEI), National Inclusion Week is a week dedicated to celebrating inclusion and taking action to create inclusive workplaces – founded by Inclusive Employers. The idea is to build awareness of inclusion and diversity in the workplace, empowering people to make long-standing change.

October 2025 – Black History Month

Throughout the month of October each year, Black History Month provides the opportunity to share, celebrate and understand the impact of black heritage and culture. Organisations can join in the celebrations by hosting team activities to learn about black history in the local area, invite a black speaker to host an internal workshop or highlight their own employee’s stories and achievements.
