What happens if there are blackouts this Winter?

Whilst the National Grid are still alleging it to be unlikely that we will face blackouts this winter, they are not able to completely rule out this possibility.

If this does take place, there may be a chance that employees who are physically required to be present in the workplace may not be able to work. So, how is this managed?

The starting point would be if a reasonable alternative solution can be mutually agreed.

In this article, we take a look at some of those alternative solutions together with options for those who cannot work from home.

Keeping the workplace open during a blackout

While there is no statutory minimum temperature for workplaces, government guidance suggests 16 degrees for sedentary jobs or 13 degrees for physical work.

Employers must also be mindful that they are obliged to provide a safe working environment for their employees, and as such, a workplace that is too cold to work in is a health and safety concern and could result in compulsory closures. A further consideration for employer would be the provision of adequate safety lighting.

Health and safety should always be the number one consideration in such circumstances, and employees should not be forced to work where there is a reasonable risk of danger.

If employees have electricity at their homes

If the business premises have no electricity but employees have access to electricity at their homes, or if they have sufficient battery life on their IT equipment to enable them to work (and access to mobile data), then a reasonable alternative solution would be to request employees to temporarily work from home during any blackouts. If employees can work from home, but have to use their own personal devices, you will need to draw their attention to your policies concerning GDPR.

If employees don’t have electricity at their homes

If a blackout extends to employees’ homes, then you could ask employees if they would be willing to make up the time out of working hours when they have access to electricity. Employees may also explore the option of working from a suitable alternative venue, such as a hot desking space or a local coffee shop which does have electricity (subject to the organisation’s confidentiality procedures).

Employees who cannot work from home

Some employees’ duties will not enable them to work from home. In such circumstances, the following could be offered:

Annual leave

You could request that employees use their annual leave entitlement in such circumstances, which will be of benefit to them as they will not suffer a loss in their remuneration.

If planned blackouts are announced in sufficient time, then employers can require staff to take annual leave.  The notification requirement is twice as long as the leave itself. So, if there is a blackout for one day, for example, then two days’ notice has to be given.

Unpaid leave

If employees have no annual leave left or they are simply unwilling to use their annual leave for such circumstances, they could take a period of unpaid leave. The unpaid leave would be subject to mutual agreement, and we would recommend obtaining an employees’ consent to this in writing.

Lay-off or short-time working

Subject to what an employee’s employment contract says, you may have the right to contractually lay-them off for a set period, or put them on short-time working, which is a temporary reduction to their hours of work. There’s no limit for how long you can be laid off or put on short-time working, however employees can apply for redundancy and claim redundancy pay if it’s been 4 weeks in a row or 6 non-consecutive weeks in a 13-week period. If the employment contract doesn’t provide full pay in such circumstances, employees may be entitled to a statutory guarantee payment.

School closures

If schools face compulsory closures, many staff who have school age children will have to juggle childcare whilst working. If possible, you may wish to allow employees to work from home (if their duties allow for this). If that is not possible you may permit them to take annual leave or remind them of their statutory right to take a reasonable amount of unpaid time off to care for dependants.

Employers will need to be mindful that some employees may not be able to be as flexible as others due to childcare issues. If a fixed approach is taken, an employer may be unintentionally putting the business at risk of sex discrimination claims as statistically, more women than men have childcare responsibilities.

What if you don’t want employees to work from home?

If an employee has access to electricity at home (and the workplace does not and has forced a mandatory shutdown on account of no electricity) and the employee has the ability and equipment to enable them to do so, then it may be considered unreasonable to refuse them to work from home, particularly if they have previously done so (such as during the pandemic).

If you choose not to permit them to work from home, but they are otherwise able to work, then arguable they are entitled to be paid their contractual rate of pay, as they are otherwise willing and able to perform their work. Organisations could be at risk of an unauthorised deduction from wages and breach of contract claim.

Abuse of the circumstances

If you suspect that there may be some members of your workforce who would abuse a right to be paid to be at home during a blackout, please make it clear that any employees who provide misleading information regarding their power supply will face disciplinary action.


It is always best practice to ensure that all these situations are recorded in the Staff Handbook – particularly in the homeworking, hybrid-working and health and safety policies so that employees are clear on what will happen, and employers will be able to manage expectations.
