Highlights
- The Government's long-anticipated Warm Homes Plan backs the upgrades that really pay off, including solar panels, batteries and heat pumps
- By bringing zero-bill homes closer to reality, this low-carbon tech delivers real savings, particularly when paired with the right energy tariff
- More than six in 10 (62%) now say that solar panels and heat pumps are a must have when purchasing their next home
- EDF is helping households turn long-term investments into real savings, with its Empower Exclusive tariff having the potential to cut bills by up to £947 per year for customers installing solar or battery systems.*
UK households could save up to £947 a year on their energy bills by upgrading their homes with solar panels or batteries and switching to an EDF smart tariff*, as the Government today publishes its long-anticipated Warm Homes Plan.
The Plan supports UK households to make easier and more affordable upgrades to their homes, including new insulation, solar panels, batteries and low-carbon heating, helping to cut bills for thousands of homeowners.
Research from EDF highlights energy efficiency is becoming essential. More than six in ten (62%) homeowners say solar panels, batteries, insulation and heat pumps are non-negotiable for their next home, while almost half (44%) want solar panels if they don't have them already.
These upgrades are not only helping households cut bills, but also boosting long-term value. Even in a steady housing market, energy-efficient and future-focused improvements continue to stand out, with the right changes helping some properties achieve value uplifts of up to 14%, based on recent research from Purplebricks**.
EDF is helping households turn this growing demand for energy-efficient homes into real financial savings. Its Empower Exclusive tariff could cut bills by up to £947 per year for customers installing solar or battery systems*.
EDF also offers a full suite of Low Carbon Home upgrades, including smart meters, solar panels, batteries, EV chargers and heat pumps, alongside tailored tariffs to help customers get the biggest return on investment from their technology.
Martin Alyward, Head of Zero Carbon Homes at EDF said: "With the launch of the Warm Homes Plan, we hope to see more households getting access to energy-efficient home upgrades that genuinely pay back. By combining Government support with our Solar, Battery and Heat Pump products and exclusive tariffs, we're helping families cut bills now, look after the planet and save even more for the long-term."

*Savings based on January 2026 Standard Variable Price Cap and dependent on household consumption patterns. The average saving of more than £800 per year compared to the price cap assumes Ofgem typical consumption, payment by Direct Debit and national average tariff rates. A typical household (of 2-3 people and with 10-12 panels) on Standard Variable Tariff (2,700 kWh consumption with Standard electricity meter) would pay £947 per year for electricity based on January 2026 energy price cap rates. A typical household (of 2-3 people and with 10-12 panels) with 2,700 kWh of solar generation and a battery with a capacity of 3kWh will pay £0 over a year, based on January 2026 (Import and Export) Empower Tracker Exclusive 12m v2 & Export Exclusive 12m v2 tariff rates. Assumes that solar generation is prioritised to power the home with excess stored in the battery. Battery discharge is prioritised for use in peak hours. The battery is topped up using imported energy in night/off-peak hours and discharged during the peak. Excess energy not used for the home/ when the battery is full is exported.
**Based on Purplebricks sales data of property sold prices of homes with EPC A/B uplift. A higher EPC comes from using less energy to power and heat homes, this could include but is not limited to solar panels, heat pumps, smart meters, renewable energy systems, insulation.
