From precision nuclear contracting at Sellafield to award-winning builds across Cumbria – William King Construction delivers where standards cannot be compromised.
William King Construction is a family business built on a simple belief. That construction done properly, with the right people, the right knowledge and a genuine commitment to quality, makes a real difference to the buildings we leave behind and the communities we work in.
From our roots in bespoke residential builds across Cumbria and the Lake District, we have grown into a multi-disciplinary contractor trusted by some of the most demanding clients in the UK. We work on nuclear sites that require the highest levels of compliance and precision. We restore listed buildings that require sensitivity and specialist craft. We deliver commercial projects for national brands to tight deadlines. And we build homes that win awards.
What connects all of that work is not the scale or the sector. It is the people who deliver it and the standards they hold themselves to, every single day.
