DESCRIPTION: The energy market has changed significantly in recent years. Here's how switching works in 2026 and whether it can actually save you money.
SECTION: Has the Energy Market Returned to Normal?
Following the energy crisis of 2021–2022, when dozens of suppliers collapsed and fixed-rate deals disappeared from the market, the UK energy market has gradually stabilised. By 2025–2026, fixed-rate tariffs had returned and the difference between the cheapest deals and the price cap default tariff had widened enough to make switching worthwhile again for many households.
However, the market remains more cautious than before 2021. Fewer suppliers are offering ultra-competitive fixed deals, and the price cap set by Ofgem continues to influence the market rate for households on default (variable) tariffs.
SECTION: Understanding Your Current Tariff
Most households who haven't actively chosen a tariff will be on their supplier's standard variable rate — a tariff that tracks (but is not identical to) the Ofgem price cap. The price cap limits what suppliers can charge per unit of energy and for the standing charge, but it's a cap on the rate, not the bill. Your actual bill still depends on how much energy you use.
If you've previously switched to a fixed-rate deal, check when it ends. When a fixed deal expires, you typically roll onto the supplier's standard variable rate — which may be higher. Set a calendar reminder for when your deal is due to expire.
SECTION: Should You Fix or Stay Variable?
This depends on your view of where energy prices are heading:
- Fix if: You want price certainty and current fixed deals are competitive relative to the price cap.
- Stay variable if: You believe prices will fall and don't want to be locked into a higher rate.
There's no universally correct answer, but locking in a fixed deal when prices are high can be a costly mistake. Conversely, staying variable when prices are rising can also be expensive. Most financial guidance suggests that unless you have a strong view on direction, a modest 12-month fix at a good rate offers a reasonable balance.
SECTION: How to Compare and Switch
Use comparison sites to check the market:
- Uswitch (uswitch.com)
- MoneySuperMarket
- Ofgem's own Confidence Code-approved sites
You'll need your postcode, current supplier name, current tariff name, and your annual usage in kWh (found on your bill). Input this and the site will show you comparable costs across available deals.
Check the exit fees on any deal you're considering — some fixed deals carry fees if you leave early. Also check the payment method — some rates are for direct debit only.
SECTION: The Switching Process
Once you've chosen a new deal, switching is straightforward:
1. Apply online with your new supplier — the process takes around 15 minutes.
2. Your new supplier handles the switch. You don't need to contact your old supplier.
3. The switch typically completes within 5 working days for most consumers (it was 21 days previously — Ofgem shortened this).
4. Submit a meter reading to both suppliers on the day the switch completes.
5. Your old supplier sends a final bill. If you were in credit, they must refund you within 14 days.
You cannot be charged a fee for switching if you're on a standard variable tariff. If you're on a fixed deal, check whether an exit fee applies before switching.
SECTION: Smart Meters and Switching
If you have a smart meter and switch supplier, your smart meter should remain smart — it won't revert to a basic meter. However, in-home display readings may temporarily stop working until your new supplier's systems connect. This is a known issue and usually resolves itself within a few weeks.
SECTION: Collective Energy Switching
Some local councils and community groups run collective switching schemes, where households join together to negotiate group discounts with suppliers. These are advertised periodically and can offer rates that beat the open market — worth watching for through your local council's communications.
SECTION: SimpleMoney Verdict
Energy switching is back as a meaningful money-saving exercise in 2026, though the savings are typically more modest than before the energy crisis. If you're on a standard variable tariff and haven't compared recently, use a comparison site. Even saving £100–£200 per year is worth 15 minutes of your time.
