# Best UK Heat Pump Electricity Tariffs (2026)

Running a heat pump on a standard flat-rate electricity tariff is an expensive mistake. By switching to a specialized smart time-of-use tariff, you can heat your home for as little as **12p per kWh**.

## Smart Tariffs Cut Heating Bills by Up to 60%

A heat pump with an SCOP of 3.8 running on a **12.5p/kWh off-peak smart tariff** delivers heat at an effective cost of just **3.29p per thermal kWh**—nearly half the cost of burning mains natural gas ( 6.2p/kWh ).

## Top 5 UK Heat Pump Tariffs Ranked (2026)

## Detailed Analysis of Leading Tariffs

### 1. Cosy Octopus (The Undisputed Industry Leader)

Cosy Octopus is designed specifically for heat pump owners. Unlike standard Economy 7 which only gives off-peak power overnight, Cosy Octopus provides **three separate off-peak boost windows** totaling 8 hours every day:

- **Morning Slot (04:00 – 07:00):** Pre-heats your home and hot water cylinder before the morning alarm.
- **Afternoon Slot (13:00 – 16:00):** Boosts internal thermal mass during solar/wind generation peaks.
- **Late Night Slot (22:00 – 00:00):** Recharges domestic hot water for night-time showers.

### 2. Agile Octopus (For Battery & Solar Homes)

Agile Octopus updates electricity prices every 30 minutes based on day-ahead wholesale market prices. During periods of high North Sea wind generation, prices frequently drop below **5p/kWh** or even turn negative (where you are paid to consume power).

#### Pair Your Heat Pump With BLUETTI UK Home Battery Storage

Charge your battery overnight on off-peak rates (from 12p/kWh) and power your heat pump during expensive daytime peak hours. BLUETTI whole-home modular storage systems qualify for 0% statutory VAT in the UK.

### 3. OVO Heat Pump Add-On

OVO offers an 'Anytime' heat pump rate of 15p/kWh for the electricity consumed specifically by your heat pump, without changing your household unit rate. A great option for homeowners who do not want to schedule their heating around fixed time blocks.
