Tony found the best deals available to us on the market for our water, gas and electricity.

Tony also managed the move across so we had very little to do. Excellent service and value.

Dave Horner, Smith Bros (Caer Conan) Wholesale Ltd.

Was offered an electricity supply check after purchasing eco showerheads from SaveMoneyCutCarbon.

It was to my advantage to change to a new supplier which we did and the whole process went through without any problems. I am still satisfied after nearly a year with the new supplier. Thank you SaveMoneyCutCarbon.

Chris Dennis, Presbytery Guest House

Swapping energy suppliers was easy, we didn’t have to do anything as SaveMoneyCutCarbon handled the whole process.

The best bit is we’re saving money and supporting a local business at the same time.
