Who supplies gas and electricity in Swindon?
Swindon is on the national gas and electricity grids. There is no single "Swindon" supplier – dozens of energy companies supply homes and businesses in the area. Your supplier is the company you pay for gas and/or electricity. You can have different suppliers for gas and electricity. To find out who supplies your property, use findmysupplier.energy (you’ll need your postcode and address).
How to switch energy supplier or tariff
You can switch to a different supplier or to a different tariff with your current supplier. The process is usually straightforward: compare deals (using an Ofgem-accredited comparison site or directly with suppliers), choose a tariff, and the new supplier handles the change. Your supply is not cut off. If you're in credit with your old supplier, that will be refunded. For current deals and whether switching is worthwhile, see our guide to cheapest energy deals in Swindon.
What to compare
Look at the unit rate (pence per kWh), standing charge, and whether the tariff is fixed or variable. Fixed tariffs lock in rates for a set period; variable tariffs can go up or down. Check exit fees, contract length, and any green or other benefits. Your usage (in kWh) is the main driver of cost – use your last 12 months of bills or a smart meter to compare accurately.
If you're struggling to pay
Contact your supplier as soon as possible. They must offer a payment plan and may have grants or schemes. Citizens Advice and the GOV.UK energy support pages have more on help available.
Information correct as of February 2026. Tariffs and market conditions change. Always check current deals and official sources before switching.
