Women in Construction
Women in Construction
We support women in construction. While women currently make up only 5.5% of the construction workforce, Mercury is leading the way in making strides to both attract a high quality and diverse team and help to make the construction industry more female friendly.

As part of this, we’ve previously hosted “Women in Construction Week” across Mercury. The focus of the initiative is to highlight women as a valuable component of the construction industry. Led by our HR department, we use the occasion to raise awareness of the opportunities available to women in the construction industry and to emphasise and encourage the growing role of women in our industry. We recognise the achievements of women in our company and hope that they will inspire others to follow in their footsteps and encourage other female employees across our organisation.
We’re hugely proud of the contributions made by women within Mercury.
