A Brief History

William King Construction was formed in 1984 working on major pipeline projects around the world, alongside large global companies such as IPCO Marine. When William King Jnr. took over the business he focused on Civil construction.

Our priority was building multiple, award-winning, luxury homes across the North West of England. Our quality was recognised by Mitie who are responsible for the maintenance of the vast majority of Sellafield, and thus we were invited to partner alongside them to help them deliver a successful project to their client.

We are proud of our history with Mitie and continue to provide reactive and preventative maintenance support to them after nine years, forming a great working relationship.

We continue to build quality, luxury homes alongside large multi-skilled civil teams who work with multi-national companies delivering quality driven packages on the Sellafield site in Cumbria.
