About SMC Plumbing & Heating
Built in Cardiff. Built on care.
Since 2011, SMC has grown around a simple promise: honest advice, careful workmanship and making sure every job is done properly.
Cardiff based · Established 2011Where it began
A business built around the customer.
SMC started in 2011 with a simple belief: customers deserved better communication, honest advice and work completed with genuine care.
It was never about becoming the biggest company or rushing through the most jobs. It was about building trust, taking pride in every detail and leaving each home knowing we had done the best job possible.
The vans, the team and the business have grown, but the values remain the same. We keep learning, investing and improving because every job carrying the SMC name matters to us.
Then and now
The business grew. The values stayed.

Experienced engineers, apprentices and the same straightforward approach on every job.

Shayne
Shayne’s work is coming along as nicely as his smile. He works hard, is always polite and regularly gets mentioned in customer feedback for being friendly and respectful.

Engineer
Rob
Rob has been part of the furniture at SMC for the last eight years. He’s a hard worker and a dependable pair of hands—happy on the job, but even happier when Friday comes around.

First-year apprentice

The youngest of the bunch, Caden brings an amazing smile and plenty of enthusiasm. He’s still finding his feet, but he’s putting the hours in and learning the most important lesson: hard work pays off.
