OVO Energy Heat Pump Tariff: What's Available in 2026

By Home Heat Pump Guide
UK semi-detached house where OVO Energy customers could save more by switching to a dedicated heat pump electricity tariff
OVO Energy customers with heat pumps should compare their rates against dedicated heat pump tariffs from competitors.

OVO Energy does not currently offer a dedicated heat pump tariff — and that matters. While OVO's standard rates are competitive at around 23-24p per kWh, heat pump owners on a flat tariff are missing out on the £200-380 annual savings available through time-of-use tariffs designed specifically for high-electricity households.

In this review, we examine what OVO currently offers, where they fall short for heat pump owners, and whether you should consider switching to a supplier with a dedicated heat pump product.

What OVO Offers Heat Pump Owners

Product Rate Time-of-Use? Heat Pump Benefit
OVO Standard Variable ~23-24p/kWh No Slightly below cap rate
OVO Fixed Deals ~21-24p/kWh No Price certainty
OVO Greenlight Informational Signals only Usage awareness

Rates as of Q1 2026. OVO's rates are competitive but lack the time-of-use structure heat pump owners need.

OVO's standard rate is slightly below the Ofgem price cap, which is better than many Big Six suppliers. But without off-peak windows, a heat pump using 4,000 kWh per year still costs approximately £940 annually — versus £600-660 on dedicated heat pump tariffs.

How OVO Compares to Heat Pump Tariffs

OVO costs £280-340 more per year than dedicated heat pump tariffs.

OVO Greenlight: Smart but Not a Tariff

OVO Greenlight shows you half-hourly carbon intensity and pricing signals through the OVO app. It helps you understand when electricity is cheapest and greenest — but it does not change what you pay. It is informational rather than a tariff.

If OVO converts Greenlight into a genuine time-of-use tariff with cheaper off-peak rates, it could become competitive for heat pump owners. Until then, it is a nice feature but not a reason to stay.

OVO's green credentials are strong, but heat pump owners need tariff savings, not just carbon signals.

Should You Switch Away from OVO?

If saving money on your heat pump is a priority, yes. Switching to Octopus Cosy could save you £280-340 per year. Even Scottish Power SmartGen saves significantly more than OVO's flat rate.

The only reasons to stay with OVO are if you highly value their green credentials (100% renewable electricity), are locked into a favourable fixed deal, or are waiting for OVO to launch a dedicated heat pump tariff.

Frequently Asked Questions

Does OVO Energy have a dedicated heat pump tariff?

As of early 2026, OVO does not offer a dedicated heat pump tariff with special rates. They offer competitive standard and fixed-rate tariffs plus Greenlight half-hourly pricing signals, but lack the time-of-use structure that benefits heat pump scheduling.

Is OVO cheaper than Octopus for heat pump owners?

Generally no. OVO's flat rate of around 23-24p/kWh is competitive but cannot match the effective 15p/kWh average achievable on Octopus Cosy with off-peak scheduling.

What is OVO Greenlight?

OVO Greenlight shows you half-hourly carbon intensity and pricing signals through the OVO app. However, it does not change what you pay — it is informational rather than a tariff.

Should I switch away from OVO if I have a heat pump?

If saving money is your priority, yes. Switching to a dedicated heat pump tariff could save you £200-380 per year. See our 10 tips for cutting heat pump costs for more ways to save.

Will OVO launch a heat pump tariff?

OVO has been expanding their smart tariff offerings and market pressure from Octopus makes it likely they will develop heat pump-specific products. Nothing has been confirmed at the time of writing.

OVO Energy in the UK Heat Pump Landscape

OVO Energy's position highlights a gap in the market for environmentally conscious heat pump owners who want both green credentials and cost-effective tariffs. While OVO supplies 100% renewable electricity, the lack of a dedicated heat pump pricing structure puts them at a disadvantage against more innovative competitors. As heat pump adoption grows under the Boiler Upgrade Scheme and improved home insulation standards, suppliers who combine green energy with smart pricing will capture the largest share of this growing market. Solar panel owners may find OVO's export rates worth evaluating alongside their heat pump tariff decision.
