What Our Customers Say
Kevin Dunn, Director
“Dear Ben & the Team at Jonstar,
A post that Ben Stocking put on LinkedIn piqued my interest last year that talked of the real green commercial energy suppliers.
Having spoken to Ben about this, he reviewed our energy supply in our new offices.
He was able to find us a competitive deal but more importantly for Furnley House who are passionate about sustainability – it was with a true green supplier – Ecotricity.
Thanks to Ben and all the team at Jonstar for all your work and fabulous service – it was greatly appreciated.
I would have no hesitation in recommending your services to any of our clients.
Thaliwal & Co Solicitors
“Our experience of Jonstar Energy Brokers was excellent and completely ‘hassle free’ in terms of our input as they took the initiative, led all the relevant dialogue with the companies and fed back to us with a very simple and clear answer as to the options that we had available to us.
The reality is that the service was without any charge to us at all and of course with no commitment to have to alter a supplier if we did not wish to do so.
In our case the involvement led to a saving of money and we would be very happy to recommend them and will be retaining their help and support going forward.
In terms of any Commercial energy cost savings I would thoroughly recommend that you take them up on a free no obligation comparison.
There is literally nothing to lose and potentially everything to gain!”
“We are very very happy with Jonstar. Jonathan and his team are extremely efficient and professional at what they do.
You’ll always get an honest and straight forward answer. He has provided us with really good pricing and takes all the worry of dealing with energy off our shoulders.
No hard sales or any of the dishonest tactics you get from any of the others. I can assure any prospective client that the team at Jonstar are everything a broker should be. You won’t be disappointed”
I am Chairman of Bostik Premier League Merstham FC.
I would definitely recommend Jonstar Energy Brokers for the very courteous, helpful manner in which they helped me get the best value prices for electricity and gas that I could find.
I will certainly be using Jonstar again when I renew my business utility contracts.
