Yes, energy prices can change from day to day and will typically rise year-on-year. Many factors can influence this, including fluctuations in market rates. Also, as the UK imports gas and electricity, environmental changes - such as severe weather conditions - can impact the price you pay for energy. The best way to ensure you get the price possible is to secure a new deal as soon as possible. You can start looking for new deals between 6 and 12 months before your contract ends, so if you’re prepared, you could make some big savings - and fix that rate for up to 5 years!
