Vattenfall Electricity

About this deal

Vattenfall is a large, well-known supplier with a distinct green-energy focus and a particularly strong presence in bigger cities like Berlin and Hamburg. If you want the reassurance of a major, long-established company but care about where your electricity comes from, it sits in a useful middle ground: big enough to feel dependable, with renewable tariffs front and centre.

Sign-up is done online, and the range includes fixed tariffs that lock your working price for a set period. In a market where prices can swing sharply, a fixed rate buys predictability, letting you budget for the year without worrying about the next market spike. That certainty is the main reason to choose a fixed deal over a variable one.

Best for

• City households wanting a big supplier with green credentials
• People who value a fixed price and predictable annual budgeting
• Anyone who prefers an established brand over an unknown reseller

Honest caveat: a fixed price protects you if the market rises, but locks you in if it falls, and the longer terms mean a real commitment with a cancellation notice to respect. As with most big providers, the eye-catching rate often includes a first-year bonus that disappears in year two. Check the guarantee length, the term and the notice period, compare the ongoing price against the market, and diarise a review before the bonus runs out.
