How to find the cheapest deal
Cheap electricity
Look at unit rate (p/kWh) AND standing charge. Time-of-use tariffs (e.g. Economy 7, EV tariffs) can be cheaper if you can shift usage to off-peak.
Cheap gas
Compare on annual cost, not headline rate. A low unit rate with high standing charges can cost more if you use little gas in summer.

Actionable advice
- Always compare on annual cost, not unit rate alone.
- Factor in exit fees if you'd switch again within 12 months.
- Avoid prepayment meters where possible — they cost more on average.
- Check renewable / green tariffs — many now match standard prices.
- Re-check every 6 months — the cheapest deal moves often.
