They are a renewable energy supplier and offer 100% renewable energy, offset gas which includes a percentage of green gas. Find out more about Bulb renewable energy and what they do to make their energy green.
Bulb Energy tariff
At the time of writing the cost of their Vari-Fair tariff has a daily standing charge of 20.87p for electricity and 20.44p for gas. This is a little on the high side suggesting Bulb are targeting a slightly above average energy user rather than households that are more frugal with their energy.
The unit cost for electricity is 16.011p per kWh and the gas is priced at 2.720p per kWh. In overall terms compared to the whole of the market this is at the lower end but more expensive than the smaller budget energy companies.
