Consumer Energy Solutions (CES), a green energy company that retrofitted properties under the UK government's ECO4 scheme, entered administration last Friday, leaving numerous customers with what they describe as "botched" and incomplete work. The company, which provided insulation, heat pumps, and solar panels to low-income and vulnerable households using grant funding, has sparked concerns over the quality of work and the financial implications for affected homeowners.

Jane Wallbank, a 36-year-old resident of Penrhiwceibr in Rhondda Cynon Taf, told the BBC that signing up for wall insulation with CES in October 2025 was "the worst decision she's ever made." Wallbank reported that her home flooded during the insulation work, leaving her in a position where she is trying to "rebuild" her life. She is one of several CES customers who have come forward to detail the "nightmare" experiences they have faced.

The ECO4 scheme, under which CES operated, is a government initiative designed to provide grant funding for energy-efficient upgrades to homes occupied by low-income and vulnerable individuals. The collapse of CES raises questions about the oversight and quality control measures in place within the scheme. Ministers have admitted that approximately 30,000 homes have been fitted with substandard insulation under various government schemes.

KR8 Advisory Limited, the administrator for CES, has advised affected customers to contact insurance-backed guarantee providers for assistance. The administration of CES has also resulted in the loss of hundreds of jobs. The full financial impact of the company's failure on both customers and the broader market remains to be seen. The BBC has reached out to CES for comment but had not received a response as of press time. The situation highlights the potential risks associated with government-backed green energy initiatives when quality and oversight are not adequately maintained.
