Employers are only required to carry out a risk assessment for a pregnant worker if certain conditions are met.

The Employment Appeal Tribunal has held that an employer will only be required to carry out a risk assessment for a pregnant worker, if the following conditions are met:
- The employee must notify their employer that she is pregnant.
- The work that the employee carries out must be of a kind which could involve a risk of harm or danger either to her health and safety or that of her baby.
- The risk must come from either processes, working conditions or physical, chemical or biological agents within the workplace.
