Switching questions
Can I switch supplier if I already receive support?
Usually yes. Most support schemes are independent of your tariff choice, but always check scheme terms before switching.
How much could I save by switching?
Savings vary by postcode, usage, and tariff type. Many households on standard variable tariffs can reduce annual costs by moving to a cheaper fixed tariff.
How long does switching take?
Most switches complete within around five working days once your application is accepted.
Will my supply be interrupted?
No. Your gas and electricity supply continues as normal during a supplier switch.
