Do: Switch supplier if it means you will save money.

Don’t: Assume your new energy tariff will remain the cheapest forever.

Do: Use an online comparison site to find your cheapest deal.

Don’t: Switch to a supplier without checking their track record.

Do: Switch to a supplier with a proven track record.

Don’t: Be afraid to switch your supplier. It’s very straight forward these days (providing you go through accredited channels).

Do: Switch your supplier again when they increase your tariff.

Don’t: put yourself off because you think it will be a load of hassle (there’s some serious money to be saved by switching to an online energy deal).

Although you may be tempted to switch to the cheapest, please be careful.

I would most likely skip through the cheapest in most cases and, switch to one of the following suppliers cheapest online tariffs.

    I recently used the Switch with Which? energy comparison site and was surprised that the top savers were mostly unknown companies. This triggered me to check out these companies on Companies House. Generally these were small (actually TINY) companies, often only ONE sole Director, very low assets and very little money in the bank ( just a few thousand). This led me to the conclusion “Don’t touch them with a barge pole” . Typical companies like top savers IRESA and AVRO. I would consequently recommend checking out any unfamiliar supplier robustly before even considering a changing.
