HSE Improvement Notices Vs Prohibition Notices

If the HSE visit your premises or site and find something wrong, they will expect you to put it right. You may get an enforcement notice, an improvement notice or a prohibition notice. But what are the differences between an improvement notice and a prohibition notice?

The HSE is the national regulator for health and safety. That means they enforce health and safety laws. If the HSE visit your premises or site and find something wrong, they will expect you to put it right.

If your workplace is found not to be complying with the health and safety laws, it's known as a health and safety breach, or being in breach of the regulations. And these breaches can lead to action from the HSE.

They may give you verbal or written advice. They might issue a formal caution. Or you may get an enforcement notice.

One of the powers of a HSE inspector is to issue an enforcement notice. These enforcement notices are a way to fix health and safety breaches quickly. It's effective immediately.

There are two types of enforcement notices issued by the HSE:

  1. Improvement Notices
  2. Prohibition Notices

Both types of notice will include a summary of the inspector's opinion and details of the breach(es) and danger(s) that have been observed. But what are the differences between an improvement notice and a prohibition notice?

While both mean there has been a breach of health and safety regulations, they have slightly different consequences.

Improvement Notices

An improvement notice, as you can probably guess, means there needs to be an improvement. It is issued when work has taken place or is taking place, that doesn't comply with health and safety laws.

The improvement notice will identify a breach in the law, that needs to be addressed.

An improvement notice applies as soon as it is issued - but it doesn't require immediate action (although you should take action as soon as you reasonably can). The improvement notice won't just tell you what needs to be improved, but also when it needs to be improved by.

A deadline. A time limit by which you need to fix the issue.

So, instead of stopping work right away, you get time to make things right. The deadline will be at least 21 days (to allow time for appeals), but it can be longer.

The amount of time given is down to the inspector. They will look at the seriousness of the breach, and how quickly it can be put right.

Of course, you shouldn't wait until the deadline to fix any problems. If any issues arise or an accident happens, and you're in breach of health and safety laws, there could be further consequences - like prosecutions or prohibition notices.

Don't forget the HSE will also fine you for the amount of time they spend on enforcement action (including improvement notices) under the Fee for Intervention. So it's best to get the matter resolved as quickly as you can.

But, putting in place safety measures can take time. If you have been issued with an improvement notice, you'll have time on your side to make the necessary changes.

If you feel an improvement notice is wrong, it can be appealed. During the appeal of an improvement notice, the notice is suspended while the appeal takes place.

Prohibition Notices

A prohibition notice is more serious than an improvement notice. A prohibition notice is issued for more severe health and safety problems, and this notice has more of an immediate impact because it stops work.

The offending activity must stop as soon as a prohibition notice is served by the HSE.

the act of officially not allowing something, or an order that does this

A prohibition notice would be issued where the inspection feels there is a serious risk of personal injury to one or more people. For example, if moving parts of machinery are not guarded, or work at height is being carried out without any edge protection.

This type of notice is usually issued in person, to the person carrying out the activity, even if they are not legally responsible for the safety measures.

This is to make sure they stop work, and the dangerous activity, right away.

A copy of the notice will then be issued to the employer, who has legal responsibilities to ensure the work is carried out safely.

Unlike the improvement notice, the prohibition notice doesn't need a deadline. Work just simply cannot happen until the matters are resolved.

Sometimes, where work is happening, the prohibition notice may be delayed to allow the section of work to finish, if stopping immediately would introduce additional risks, or for example if workers need to get to a place of safety. You'll be told if this is the case.

The work doesn't necessarily need to have taken place for a prohibition notice to be issued. Where there is an anticipation that something dangerous is about to happen, this notice can be issued to stop that work from happening.

Just like with an improvement notice, you have the right to appeal against a prohibition notice, if you feel it is wrong. However - because of the presumed danger involved - the prohibition notice remains in place during the appeal process.


While there are two types of enforcement notices, HSE inspectors have the powers to choose to issue one, the other or both. And just because the prohibition notice is more severe, doesn't mean you need to get an improvement notice first.

For example, a prohibition notice can be issued to stop a dangerous activity. It may be followed by an improvement notice to address the breaches that lead to the risks found.

Prosecutions can follow either type of notice. This could be for failure to comply with an enforcement notice, or for the health and safety breach itself.
