The Company

H.A. Marks is an award winning family owned construction services company that has been trading continually for more than 65 years. During this time we have been at the leading edge of construction, developing creative innovative and sustainable solutions to meet client’s needs. We have successfully extended our services across the country via our project delivery teams, created job opportunities and skill development in local communities where we deliver projects.

We are committed to continuous professional development and as a result are able to create better solutions for our clients who commission us to undertake projects ranging from major refurbishments; office fit outs, restoration, new build construction to reactive and preventative maintenance.

Our professional project management team have the proven ability to deliver complex projects anywhere in the UK within budget and on schedule. Our projects range from small to major construction in the public and commercial sector. We provide the complete construction solution from initial project scoping, in partnership with the client, through to project completion. A key factor in our success is the relationships we build with our clients and the local community. Our distinctive culture celebrates people, partnership and sustainability.

We continuously explore new ways for the construction industry to work together on strategic issues such as reducing waste, boosting skills and developing the communities in which we deliver projects. Our uncompromising focus on customers and a total commitment to safe and sustainable delivery are key drivers of our business.

We have a strong reputation for understanding and delivering projects, utilising sustainable technology systems within the buildings fabric in order to reduce the carbon footprint and in many cases, delivering carbon neutrality.
