Energy prices in South Wales
What the price cap lets a supplier charge in South Wales from 1 October 2026 to 31 December 2026, how that sits against the rest of Great Britain, and the cheapest tariffs I hold for a medium home. The network here is run by National Grid Electricity Distribution.
Compare for your homeOn the cap, Direct DebitThe most a supplier can charge for each kWh and each day on a standard variable tariff. Ofgem sets it every three months. It caps the rates, not your bill: use more and you pay more.£1,744a year for a medium home in South Wales at the cap's rates.The cheapest tariff I hold£51 less than the capover the next 12 months, for a medium home
£20 over the Great Britain average of £1,723: the 12th cheapest of 14 regions.
The price cap in South Wales
1 October 2026 to 31 December 2026. Pence per kWh and per day, VAT included; the last column is a year for 2,500 kWh of electricity and 9,500 kWh of gas.

How do I read this table?
Each row is one way to pay. The cap sets two prices for each fuel: a unit rate for each kWh you use, and a standing charge for each day you're connected. Here's how the Direct Debit row's yearly figure adds up in South Wales.
| Electricity you use2,500 kWh × 26.55p | £664 |
|---|---|
| Electricity standing charge365 days × 55.41p | £202 |
| Gas you use9,500 kWh × 8.09p | £768 |
| Gas standing charge365 days × 29.96p | £109 |
| A year | £1,744 |
- Per kWh
- What each kWh you use costs, in pence. Use more and you pay more.
- Per day
- A fixed charge for each day you're connected, however little you use. You pay it even on a day you use nothing.
- Economy 7 (average rate)
- Ofgem caps Economy 7 as one average rate, as if 58% of the electricity were used by day and 42% at night. Suppliers set their own day and night rates under it.
- Medium home, a year
- A year of a medium home's energy at these rates: 2,500 kWh of electricity and 9,500 kWh of gas, plus 365 days of standing charges.
Cheapest tariffs for a medium home
Priced for a medium home: 2,500 kWh of electricity and 9,500 kWh of gas a year, paying by Direct Debit on a single-rate meter. Staying on the cap comes to about £1,769 over the next 12 months, with the VAT and price changes already set.
How do I read a tariff?
Every row reads the same way. Take E.ON Next's Next Pledge Tracker 12m, part by part.
- Supplier and tariff
- Who sells it and what it's called. A tracker's rates follow an index, so they can change.
- Next 12 months
- £1,718, about £143 a month: what it would cost your home over the next 12 months, VAT included, at the use you gave (or a medium home's).
- Against the cap
- £51 less than the cap, over the same 12 months. Within £5 either way I call it about the same: the estimate isn't that exact.
- Unit and standing
- Each fuel's unit rate (what each kWh costs) and standing charge (a fixed amount a day), today, in pence with VAT. They're what you'd sign up to, so they're as big as the total.
- The small print
- How long it lasts, what leaving early costs (here: £25 exit fee per fuel) and how you pay.
- Get a quote
- Opens the supplier's own site to switch. Some suppliers may pay me if you do; that never changes the order.

How I rank, and how I make money
Cheapest first, on the estimate for your home, with ties in supplier then tariff name order. Commission never changes who's listed or the order. A link to a supplier that pays me may earn me commission if you switch through it; every other link earns nothing.
Suppliers that pay me now: none of them.
What I compare
I compare the tariffs Octopus Energy, EnergyCoop, London Power, E.ON Next, Sainsbury's Energy, EDF and Good Energy publish openly. British Gas, OVO Energy, ScottishPower, So Energy, Utilita and other suppliers don't publish theirs in a form I can use, so they aren't here. The price cap is the most any supplier can charge on a standard variable tariff.

Before you switch
- Staying put can be the deal. Ofgem's rules stop suppliers keeping a tariff for new customers only, so your own supplier's deals are open to you too. Ask yours what it offers before you move.
- Warm Home Discount. If you get it, check the new supplier offers it before you switch: not every supplier does, and you could lose it for this winter. About the Warm Home Discount
- Money owed. Pay by Direct Debit or by bill and owe your supplier money for more than 28 days? It can stop you switching until it's paid. On prepayment you can usually switch owing up to £500, which moves to the new supplier.
- Exit fees. Leaving a fix early can cost a fee per fuel. In the last 49 days of a fixed tariff there's none to pay.
