Have been with Bulb for 3 years and in two separate houses and always found them helpful and efficient on the phone. Bulb's email and SMS messages are crystal clear, something greatly welcome. Probably not the cheapest energy supplier these days, but changing every few months to save a few pounds is a nuisance. In my experience, the cheapest is rarely the best. Bulb's green credentials are important to me but talking to a real person on the phone when/if there is an account issue is essential. I can see no good reason to switch any time soon, and even if there is almost certainly going to be another price hike in energy bills.
