A university Students' Union is questioning whether "unlimited" energy contracts are value for money and has raised concerns about students being pressured into signing up with providers.
Research by Reading Students' Union claims students using "unlimited" energy packages pay an average of £2,200 more per household, compared to those setting up more traditional contracts.
It has launched a new Energy Advice Service to support students it says may not have opted for an unlimited contract if they had been aware of the extra cost.
Two providers of unlimited energy contracts responded, describing the findings as "inaccurate", and urged students to research deals before deciding what to sign up to.
