Full heating systems and radiator work, with the neat, properly run copper pipework our reviews keep mentioning.
Bathroom Installation
Complete bathroom fits and refurbishments, from first fix to a finished, tiled room ready to use.
Shower Installation
New showers supplied and fitted, sorted properly the first time so you are not chasing drips later.

24/7 Emergency Callouts
Something gone wrong out of hours? We answer emergencies day and night, and turn up when we say we will.
Pipework you would be happy to leave on show
Look through our work and one thing runs through all of it: clean, considered copper. Every boiler, every heating run, every cylinder is plumbed the way it should be, not the quick way. It is the difference between a job that lasts and a job you call someone back for.
- Oil and gas boiler installs and servicing
- Neat copper manifolds and heating runs
- New oil tanks and hot water cylinders
- Finished to a standard, not to a clock
A local name people keep coming back to
S Thomas Plumbing is Stewart Thomas and his team, an established outfit trusted by families across Llandybie, Ammanford and the wider Carmarthenshire area. Our customers do not come once. They come back, year after year, and send us to their neighbours.
That only happens one way: turning up when we say, doing the job properly, and being straight with people. It is why our reviews read the way they do.
Trusted across Carmarthenshire
Excellent service, called Saturday late morning for an oil boiler issue. Engineer onsite hour later. Amazing service to have trades that turn up as promised.
I have used S Thomas Plumbing on several occasions and found them to be nothing but professional from start to finish. They turn up on time, have time to answer questions and are happy managing changes. I would not hesitate to recommend them to anybody requiring plumbing or heating services.
I have been a customer of Stewart and his staff for many years. They have done numerous jobs for me, including installation of new showers, plumbing repairs and boiler maintenance. They have always provided an excellent and prompt service and I can thoroughly recommend them.
Friendly team, great work, modern ideas.
Good trustworthy team who have helped us numerous times.
