Source: prices and coverage

Off-street rapid charging hubs from a TotalEnergies and SSE joint venture launched in July 2024, now rolling out across the UK and Ireland. Hubs are typically 10-12 bays at 150-160kW on retail parks, open 24/7 — a different proposition from the on-street lamppost estate formerly called Source London, which is a separate network under TotalEnergies branding. Source publishes a single national rate card rather than pricing by site: 89p/kWh on contactless, 82p on the free "Entry" plan, and 70p/66p on the paid Premium plan. AC charging is 54p.

Current tariffs

You can charge on Source without any membership — the pay-as-you-go rate applies. The membership plans below lower the per-kWh rate in exchange for a monthly fee.

Pricing by charger speed

Source prices vary by the speed of the charger you plug into. The headline PAYG rate above is the most representative rapid-tier figure used in cost comparisons across the site.

Is the subscription worth it?

Source's Premium saves 19.0p/kWh vs PAYG for a £6.99/month fee. You break even at 37kWh of Source charging per month. For an average EV driver doing 7,400 miles a year (4000kWh from Source at most), the subscription pays off if you use this network often.
