Self-employed workers

"Self-employed' means that you do not work under a contract of employment and work only for yourself.

Self-employed worker means a person who works for gain or reward otherwise than (without) under a contract of employment or apprenticeship, whether or not employing others.
A person is self-employed if they run their business for themselves and take responsibility for its success or failure.
Self-employed workers are not paid through any legal wages system , and they do not have the rights and responsibilities of an employee.

For example:

Plumber,
Temporary workers like Freelancing activity
Daily Wages Labourers etc.

Most self-employed people will know if their work poses a risk to the health and safety of others.

A self-employed worker must consider the work they are doing and judge for themselves if it creates a risk or not.

For example, if a self-employed worker operates a fairground ride for the public to use, then the self-employed worker's work could affect the health and safety of other people, and that self-employed worker must take appropriate steps to protect them, as the law will apply to the self-employed worker.

Responsibilities of the Self-employed workers:

The self-employed have responsibilities that are similar to employees’:
To take reasonable care of their own H&S and the H&S of others who might be affected by their acts or omissions.

Employment law does not cover self-employed people in most cases because they are their own boss.

If a person is self-employed, they have:

protection of their health and safety
protection of their rights against discrimination (in some cases)
the rights and responsibilities set out by the terms of the contract they have with their client

Someone is probably self-employed if they’re self-employed for tax purposes, and most of the following are true:

they put in bids or give quotes to get work
they’re not under direct supervision when working
they submit invoices for the work they’ve done
they’re responsible for paying their own National Insurance and tax
they do not get holiday or sick pay when they’re not working
they operate under a contract (sometimes known as a ‘contract for services’ or ‘consultancy agreement’) that uses terms like ‘self-employed’, ‘consultant’ or an ‘independent contractor’
