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!

Since having a new boiler installed, we have seen our energy bills lowered and our living space feels both cleaner and warmer.
