Switching energy supplier every year is still worth it in 2026 for households that compare properly and avoid exit fees.
Typical Annual Savings: £200–£500 compared to staying on default or rollover deals.
Key Insight: The real value comes from comparing annually, not switching blindly. Even if you don't switch, comparison protects you from overpaying.
Understanding the modern energy market dynamics
Energy suppliers compete aggressively for new customers. As a result:
The best fixed tariffs are usually offered to new customers switching from other suppliers, not existing customers.
Existing customers are often automatically rolled onto expensive variable tariffs when fixed deals end.
Loyalty discounts are rare in the modern energy market. Loyal customers often pay 15-30% more than switchers.
If you don't switch or renegotiate annually, you're likely paying more than necessary. Suppliers bank on customer inertia — the tendency to stay put even when better deals are available. This "loyalty penalty" costs UK households billions annually, with loyal customers subsidizing cheap deals for new switchers.
The cost of staying put in the UK energy market
Your 12–24 month fixed tariff automatically expires. You're now out of contract.
Supplier moves you to a standard variable tariff (SVT) without asking for permission.
Variable tariff prices often increase without warning, sometimes multiple times per year.
Rollover tariffs typically sit close to the Ofgem price cap, which is rarely the cheapest option.
Staying on a rollover variable tariff typically costs £200-£500 more per year than switching to a new fixed deal. The price difference between competitive fixed tariffs and standard variable rates can be 15-30%. Over 5 years, this compounds to £1,000-£2,500 in unnecessary energy costs for an average household.
Typical savings from yearly energy switching
| Household Type | Typical Annual Saving | Key Factors |
|---|---|---|
| Low usage flat | £150 – £300 | Standing charge optimisation critical. Lower usage makes percentage savings higher. |
| Average household | £250 – £450 | Balance of standing charges and unit rates. Medium consumption amplifies savings. |
| High usage home | £400 – £600+ | Unit rate differences create large absolute savings. Electric heating homes benefit most. |
| Economy 7 property | £200 – £400 | Correct tariff selection vital. Wrong tariff choice can increase costs. |
| Prepayment meter | £100 – £250 | Default rates often highest. Comparison essential for fair pricing. |
Higher consumption = larger absolute savings from better unit rates and standing charges.
Switching just before fixed tariff ends maximizes savings versus rollover variable rates.
Standing charges vary by UK region, affecting savings potential differently across areas.
