With the cost of living going up in Spain and my pension going down, when I saw the advert to reduce my electricity bill, I thought I would give them a call.

Right from the start, the staff were courteous and professional and I had total confidence that when they changed my electricity provider, they would change me to a much lower tariff - just as they said they would.

I was not disappointed! My bills are 40% less than they were six months ago and I am really, really pleased I made that call. I would highly recommend the service to anyone.

Mr & Mrs Clifton: Rojales

We received a phone call from iberswitch SLU, that was the first we knew about deregulation. Until then, like everyone else, we were paying whatever Iberdrola charged us but complaining about it at the same time.

We did the changeover because we were tired of paying what we thought was over the odds. It turned out to be the best thing we did. Our electricity bill was one of our highest outgoings, not any more. We are saving more than we imagined possible.

My advice? Call iberswitch SLU, change from Iberdrola, save money on your electricity bill.

Mr & Mrs Jackson: Fuengirola

We changed to iberswitch SLU from Iberdrola because we wanted to save money, but we didn't want to have the responsibility of contacting our electricity provider. iberswitch SLU did everything.

It took a while to go through but we are glad it did. We are only sorry we waited so long.

Mr & Mrs Brown: Mazarron

When one of the iberswitch SLU people knocked our door, we immediately though it must have been a scam. Reduce our bill by up to 45%? Charge us €30 to get connected? No thank you. We did nothing until one of our neighbours showed us their bill and told us how much they were saving.

We now tell everyone we can about iberswitch SLU. They did exactly what they said they would and, they keep an eye on our bill each month in case there is another chance to save even more money.

Mr Watkins: Denia

A friend told me about the possible saving on my electricity bill if I used iberswitch SLU to change suppliers. The savings I made were great but the biggest benefit to me was being able to speak my own language when I recently had a problem.

The situation was dealt with quickly and professionally and I am completely satisfied with the service I received. Thank you iberswitch SLU.

Mr Weaver: La Manga

My wife organised the change over of our electricity with iberswitch SLU while I was out of the country working.

When she told me, I was a bit concerned that we may experience problems due to the change. We didn't. Our bill simply changed to a different provider and apart from that and the fact the bill was reduced by about €35 a month, you wouldn't have known anything about it.

Sceptical at first - totally convinced now that it was the right thing to do.
