Stoke-on-Trent City Council says it's trying to find out just how big customer service issues are at the energy company Solarplicity.
Ofgem has banned the company from bringing in new customers for three months.
The council partnered up with the renewable energy firm in May last year in its "community energy scheme", which involved installing solar panels on homes - it's understood 5,000 households in the city have signed up.
The council says it's aware a small number of residents have experienced problems and it is seeking assurances from the company.
Solarplicity has told us it has improved and that the ban doesn't affect the solar panel scheme.
