Energy - frequently asked questions....
Will there be any interruption to my supply?
No, there is no interruption whatsoever. There is no need to change any meters, wires or pipes - your new energy supplier will use the same ones as your old one. The only changes that you will notice will be a lower bill and improved customer service from us and your new supplier.
How much will it cost us to change?
Nothing. ADSI are paid commission by the supplier, you pay nothing to us or them.
What details do I need to supply?
Just send us your latest gas and electricity bills and one of our consultants will analyse them taking into account your current usage and tariffs. ADSI are not obligated to any energy supplier so our advice will be completely impartial and will be the best deal available for you and your company. Don't forget our bill checking is completely FREE.
Do I need to contact my current supplier?
No, ADSI will organise and complete the whole switching process for you. Your energy consultant at ADSI will ensure the whole process is done smoothly and hassle free. You will have to sign a permission form to authorise ADSI to act on your behalf for your old supplier and also a direct debit form for the new supplier.
How can I claim money back?
If you have a case for either incorrect readings or overcharging with your current / previous supplier, ADSI will put together all the information and prepare a claim for you. This may involve you providing previous bills back to when you wish to claim for. However, it will be a completely stress free service by your energy consultant.
Can I have the same supplier at all the sites?
Yes, we can arrange for multiple sites with the same energy provider, making billing simpler. Just ask one of our consultants to arrange.
Testimonials
'ADSI have provided Astrum with an outstanding service over the past year and more. My Account Manager is always helpful and available to take calls and solve any issues we have with O2. Astrum have a number of company mobile users with a high proportion who work abroad for lengths at a time which can result in high usage of calls and texts and often problems with network connections. The team at ADSI are always on hand to work through these difficulties.
I would recommend ADSI to any of my customers when looking for great service and competitive prices."
Joanne Payne, Assistant Procurement Manager, Astrum UK
’we have been with ADSI for just over a year. Most people’s experience on switching any sort of service provider is that they are promised the earth; get good service at the start and this falls away. But with ADSI we received and continue to receive a personal and efficient service which despite today’s competitive market would be hard to beat.’
Simon Bradley, Discover the World
‘Our general view is that ADSI have delivered excellent service. Personal service is always a huge bonus when it comes to dealing with the sometimes complex subject of telecoms, and our account manager has always been efficient and responsive. The main purpose of moving over to ADSI was that we wanted to achieve a better and more cost-effective solution for our mobile phones. The cost savings have been significant and the contract costs are scrutinized every month by our account manager, followed by a written report and analysis. The contract is then adjusted accordingly to best suit our requirements.'
