Mrs Valerie Readett on Trustpilot:

I am so pleased with the service I am getting. The attention to detail my monthly updates and a good deal… thank you.

Negative Customer Support Review

Tom Bolton on Trustpilot:

Nearly nine weeks after moving into a rented property and still, no direct debit set up they are effectively putting me in debt. Having spoken to 4 members of staff, I am still clueless about when the off-peak electric timings. One had no clue at all the others gave me different timings. Not happy with the service at all.
