What is Fixed contract length?
In short
A fixed contract length is how many months you commit to an energy plan, and the longer the term, the more room there is to switch early.
A fixed contract length is the number of months an energy plan commits you to before you can leave without penalty. It shapes both your monthly price and how long you are tied in, so a longer term often needs a clearer reason. 100Green and Aras Energy each offer a fixed term of 12. Alperia offers three lengths: 12, 36 and 60. Badenova offers two: 12 and 24. Base Power Company offers a single longer term of 36. Shorter terms keep the commitment light, while a longer one may suit you if you value the price it secures.
