It will be up to your employer to decide if they will open on the bank holiday or not.
The government guidance states: “This is a matter for discussion between individuals and their employer. There is no statutory entitlement to time off for bank holidays, but employers may include bank holidays as part of a worker’s leave entitlement.
“The government cannot interfere in existing contractual arrangements between employers and workers.
“However, we would expect that many workers will be able to take the day off on the bank holiday.
“We also expect employers to respond sensitively to requests from workers who wish to take the day of the funeral off work.”
The Prime Minister’s official spokesman said the day of the funeral will operate as “a standard bank holiday”.
“Obviously individual businesses will need to make the decisions about what’s right for them and discuss with their employees but there is obviously no one-size-fits-all approach.”
Why is 19 September a bank holiday?
King Charles III approved plans for the date of the Queen’s funeral to be a new bank holiday.
He gave the nod during his Accession Council, in which he was officially proclaimed the next monarch.
The government said in a statement: “Monday 19 September, the date of Her Majesty Queen Elizabeth II’s State Funeral, will be a national bank holiday.
“This will allow individuals, businesses and other organisations to pay their respects to Her Majesty and commemorate Her reign, while marking the final day of the period of national mourning.
“This bank holiday will operate in the same way as other bank holidays, and there is no statutory entitlement to time off. Employers may include bank holidays as part of a worker’s leave entitlement.
“The bank holiday will take place across the United Kingdom.”
Will it be a bank holiday every year?
There are currently no plans for an annual holiday, the government has said.
King George VI’s funeral was not a bank holiday,
No decision has yet been made about whether King Charles III’s coronation will also be a bank holiday.
A decision will be made nearer the time.
No timeline for the coronation of Charles III has been announced so far, but for reference Elizabeth II’s accession happened in 1952 but her coronation took place in 1953.
