OVO Energy tariffs - what’s available right now?

OVO currently offers two main options:

Variable tariff (price cap)

OVO’s standard variable tariff tracks the Ofgem price cap. From 1 October 2026 the cap is set at a typical annual bill of £1,723 - up £60 from Q3. OVO variable customers saw their bills rise on 1 October. This is a rolling contract with no exit fees:

• Electricity unit price: 26.11p per kWh
• Electricity standing charge: 61.41p per day
• Gas unit price: 7.87p per kWh
• Gas standing charge: 29.89p per day

1-year fixed tariff

OVO’s 1-year fixed locks in your unit rate for 12 months. Rates are currently above the price cap in which you’re paying a premium now for price certainty.

• Electricity unit price: 29.20p per kWh
• Electricity standing charge: 67.33p per day
• Gas unit price: 10.37p per kWh
• Gas standing charge: 26.46p per day
• Exit fee: £50 per fuel

Estimated annual total: £2,057.48 (based on 2,500 kWh electricity / 9,500 kWh gas) vs £1,733.65 on the variable tariff - a difference of roughly £324/year.

That means you’d pay more now to fix but you’d be protected if the cap rises in January 2027. Analyst forecasts currently suggest a rise of around 26%, which would put a typical variable bill at approximately £2,170. If that happens, fixing now at ~£2,057 saves around £113 over the year.

Worth noting there’s a £50 exit fee per fuel (£100 total) if you leave before the 12 months are up.

2-year fixed tariff

OVO also offers a 2-year fix. Rates vary by region, check OVO’s site or the comparison tool above for a personalised quote.

OVO Energy prices vs the price cap

Both fixed tariffs are currently above the variable rate and the Ofgem cap. The 2-year fix is marginally cheaper per year than the 1-year fix (£2,035 vs £2,057) but locks you in for longer and carries a higher exit fee of £95 per fuel (£190 total).

What do customers think of OVO Energy?

Trustpilot: 4.7/5 - Excellent (over 300,000 reviews)

OVO has an excellent Trustpilot score with 78% of reviews being five stars. Customers consistently praise helpful staff and efficient engineer visits with the main complaints being long phone waiting times and difficulty reaching a human quickly. However, an overall rating of 4.7/5 is a clear sign of positive customer experiences.

Which?: 61% customer score - the lowest of 17 energy suppliers

Which?’s independent survey tells a different story. OVO scored two stars across every customer measure - overall service, communications and value for money. It scored just 6 out of 15 for complaints handling and 2 out of 5 for switching. Which? notes OVO’s customer service phone line has shorter hours than some other firms’.

The gap between Trustpilot and Which? is worth noting. Trustpilot reviews are self-selected which may focus more on customers who had a good experience. Which?’s survey actively samples existing customers across the board, which tends to produce a more representative picture.

Should you fix with OVO now?

The case for fixing comes down to what happens to the price cap in January 2027. Current analyst forecasts suggest a rise of around 26%, which would put a typical bill at approximately £2,170 a year.

• If the cap rises 26%: Fixing now at ~£2,057 saves roughly £113 over the year vs staying variable
• If the cap rises less than expected: You’d pay more on the fix than staying variable
• If you fix and the cap falls: You’re locked in above the market rate and subject to exit fees if you want to leave.
