The person who prices the job is the person who does it

You won’t get a salesperson, and you won’t get whichever subcontractor happened to be free that week. Rich has been doing this for thirty years. Kai joined him in 2021. Between them, that’s the whole company.

It means we take on fewer jobs than a bigger firm would. It also means the person standing in your kitchen is the person whose name is on the van — and that when you ring, you get Rich, not a call centre.

Reviews from our recent customers — see all reviews

“Had a replacement electric shower fitted by Richard Wallis and Kai. Excellent service by both of them. Arrived on time and completed the job, tested it and all done within a couple of hours. Everything left clean and tidy. We had every confidence in them and wouldn’t hesitate in recommending them.”

Andrew Marker

“Rich and Kai took out my old boiler (which was over 40 yrs old and huge) and reinstalled a new boiler and new shower unit too. I found them to be polite, efficient and very professional and thorough - this is the service that I have come to expect from this extremely reliable company who look after all plumbing needs in my house in a timely fashion. I would whole-heartedly recommend Nicky Evans”

Nicola Jane Evans

“Fantastic service from RGW. Quick response to a leak coming through my ceiling. Problem identified and fixed in quick time. Very reasonable rates and a genuine, friendly local service. Highly recommended.”
