About CRS Energy
Warmer homes. Lower bills. Built to last.
Family-founded in 2018, we help households across Wales create warmer, safer, more energy-efficient homes, backed by a fully in-house team and Employee Ownership Trust stewardship since 2024.
Our story
From one van to 10,000+ installations across Wales.
CRS Energy began in 2018 as a small, family-run business with a simple goal: to help households across Wales create warmer, safer, and more energy-efficient homes. With one van, a small team, and a commitment to quality workmanship, we quickly established a reputation for reliability, honesty, and a customer-first approach.

Our mission
Lower bills, greater comfort, and the funding you're entitled to.
Our mission is to support households across Wales in reducing energy bills, improving comfort, and accessing the government-backed funding they are entitled to. We are committed to delivering upgrades that are safe, compliant, and built to last, helping every customer enjoy a warmer home, lower running costs, and better living conditions.
What we stand for
Clear communication. Transparent advice. Installations that genuinely make a difference.
From the outset, our values have guided every aspect of our work. We believe in clear communication, transparent advice, and delivering installations that genuinely make a difference. Whether we are assessing a property, supporting a customer through eligibility checks, or completing a full upgrade, our priority is always to provide the right solution for the home.
How we work today
One connected, in-house team, from enquiry to aftercare.
As demand for energy-efficiency improvements has grown, so have we. Today, our in-house team brings together skilled surveyors, installers, retrofit coordinators, and customer care specialists, all working within one connected process. Managing the journey under one roof means customers experience fewer delays, faster decisions, and a smoother path from enquiry to installation and aftercare.
Since 2024
Becoming an Employee Ownership Trust
In 2024, CRS Energy became an Employee Ownership Trust (EOT), placing the company into the long-term stewardship of the people who work within it. This structure ensures stability, safeguards our values, and means every team member has a direct stake in the quality of the work we deliver.
For customers, it provides added reassurance: the people improving your home are genuinely invested in getting it right.
