Trusted experts with extensive experience in the heating industry

Founded in 1985, GGT Thomas and Son Ltd is an award-winning, family business providing domestic, commercial and industrial central heating installation, servicing and repairs to customers across South West Wales.

With over 30 years’ experience, we have a wealth of expertise in designing, installing and maintaining cost-effective, energy-saving heating solutions for your home or business.

The depth of our knowledge is reflected in the broad range of services we offer – from large-scale industrial installations to small domestic jobs. Our clients – many of whom have been with us for years – trust us to provide excellent service, working with complex heating systems, to ensure they achieve the best value for money they can. We generate a lot of our work through word of mouth recommendation, something we are very proud of.

Our fully-trained engineers regularly work with multiple contractors on complex, time-sensitive commercial projects but are equally adept at carrying out a simple service on a home boiler. Whatever the project, we will always work with the client and other contractors on site to ensure that key dates are met or exceeded, and disruption is kept to a minimum.

We recognise that all our customers, commercial and domestic, need flexibility, so we will always work to fit in around with your needs and commitments. Our large team and geographical coverage means that wherever you are in Pembrokeshire Ceredigion or Carmarthenshire, we can usually have someone on hand to deal with any plumbing or central heating emergencies you are experiencing.

Whatever the job, we guarantee the highest professional standards and you can be assured that we hold the necessary accreditation for any work we carry out.

This commitment to maintaining the quality of our service has shaped our excellent reputation and is the reason that so many of our loyal customers trust us to get the job done.
