About Us

Welcome to S Energy

Serving the communities of South East and South West Wales with a combined experience of 24 years we have an excellent reputation for exceptional customer care and high quality service and results.
We have worked as installers of Natural Gas, LPG and oil central heating systems both in private domestic settings and as contractors for British Gas and other big companies. We are also underfloor heating specialists. All work is carried out to the highest standard using the latest technology to ensure efficiency and cost effectiveness.

We are committed to energy efficiency and a new boiler will undoubtedly provide increased efficiency. However, a new boiler is costly so it is important that a central heating system is custom designed to ensure you get the right boiler for your home.

In our experience no installation is the same. Therefore, it is essential that you get good advice following an individual home survey and assessment of need. Contact S ENERGY to get the central heating system that suits your home and lifestyle.

Can’t thank the team at S Energy enough for their help and guidance in the installation of our new boiler. They were fast and efficient from start to finish and made the whole process seamless. Their prices are incredibly competitive, especially considering the level of service you receive, and the performance has been incredible. I would highly recommend!

We recently invested in some underfloor heating for our new home and were simply blown away by the professionalism and expertise provided by S Energy. They ensured the installation went perfectly, custom fitting the heating system to suit our home. Our living space now feels so much warmer, and we’ve seen our energy bills lower as a result!
