£50 free credit – Bulb Energy
Bulb are an energy company that have gained a strong following of loyal customers thanks to them using 100% renewable electricity and being refreshingly transparent with pricing.
Both gas and electricity are on a variable tariff which means they're subject to market price changes.
However this is arguably better than being overcharged and the rates are typically more competitive than the 'Big Six' energy suppliers for most households.
If you're switching, Bulb will cover any exit fees, and they don't charge any themselves either if you did want to move after a price hike for example.
Right now Bulb are offering free credit to new customers who sign up through a promo link, like this one from STS editor Owen. Use this link before midnight on Tuesday 18th June and you'll both get £50 in credit.
