Just before the summer of 2025, we were incredibly proud to receive the Home Build of the Year award at the Prestige Awards!
This is the second time we’ve been recognised for our work, and it really does cement our place as one of South Wales’ leading building contractors.

It means so much to everyone at Bancs to see our hard work and commitment to quality being acknowledged. We’re fortunate to have such a brilliant team of skilled tradespeople, admin staff, and managers who make what we do possible every single day.

Being nominated for an award is always special — but to actually win is something we’re truly honoured and grateful for.
As a forward-thinking company, we’re excited to keep building on this success and continue proving why Bancs is a name associated with quality, trust, and excellence.

We were incredibly proud to be awarded Highly Commended in the ‘Trade & Construction Business of the Year 2024’ category at the Prestige Awards.

This marked a major milestone for Bancs Building Contractors — our first-ever industry award and a defining moment in our journey.

Receiving this recognition gave us the reassurance that we were moving in the right direction. It reflected the hard work, dedication, and craftsmanship that go into every project we take on.

More than just an accolade, it became a catalyst for rapid growth within the company. It inspired us to raise our standards even higher and continue building on the progress we’d made.

Since then, our focus has remained clear: to deliver a high-quality, reliable service that our customers can trust — and to keep pushing the boundaries of what a modern building contractor can achieve.
