Black Friday goes orange: EDF reduces upfront costs of solar panels and heat pumps to help households cut energy bills
- EDF is helping customers reduce their exposure to rising energy prices by cutting the upfront costs of solar, batteries and heat pumps in November
- Households can get a free battery worth up to £1,620 when purchasing solar panel systems, with the potential to reduce electricity bills to £0 in their first year
- Air Source Heat Pumps, which are between 300% and 400% more efficient than a gas boiler, have £500 off, with a free seven-year service and warranty package worth £7501 included
With household variable energy prices expected to increase by around £400 in January, EDF is helping more customers electrify their homes and take control of their energy by reducing the upfront cost of installing low carbon technologies.
Turning Black Friday “orange” this November, EDF is offering savings of more than £1,600 on solar installations, and up to £1,200 for air source heat pumps.
With interest in solar panels and heat pumps rising by 27% and 41%2 respectively over the last year, households are increasingly looking for ways to take greater control of their energy use, reduce running costs and future-proof their homes against rising energy prices.
EDF predicts the January 2027 price cap will increase by 27%, with the average dual fuel standard variable tariff annual bill potentially being as high as £2,167.3 Gas prices in particular are expected to rise with a standing charge of 0.31 £/day and a unit cost of 9.76 p/kWh.4
Solar savings to brighten up your winter days
From now until 29th November, customers who purchase a 4kW solar panel system through EDF’s installation partner Contact Solar will receive a free 5.12kW Sunsynk Elite battery worth £1,620.5 This battery will include the required battery management system, power distribution unit and base.
The battery allows homeowners to store excess electricity generated by their solar panels and use it when they need it most, helping maximise the benefits of home-generated renewable energy. On average, a 5.12kW solar battery stores enough electricity to power two cycles of a washing machine or run four full dishwasher loads.6
Plus, when purchasing a solar panel system with Contact Solar, customers will gain access to exclusive EDF import and export tariffs, Empower Fixed Exclusive 12m and Export Exclusive 12m, with payments of 18p for every kWh exported during the first 12 months.
With the Empower Fixed Exclusive 12m and Export Exclusive 12m tariffs, a typical household with 2,500kWh of solar generation could potentially reduce their bill to nil for 12 months.7
Smarter home heating for a warmer winter
For homeowners considering a heat pump, EDF is also offering £500 off the cost of a new air source heat pump installation.8 Customers who purchase a Daikin or Ideal heat pump via EDF will get free seven-year servicing and warranty package worth £750, providing them with added peace of mind and long-term value when upgrading their home’s heating system.
The offer can also be paired with the government’s Boiler Upgrade Scheme (BUS), which entitles eligible customers to grant up to £9,000 until 31st March 2027. This means households hoping to make the switch away from oil and LPG are now able to install an EDF heat pump from as little as £4,100.9
Air source heat pumps are typically 300-400% more efficient than a standard gas boiler, making them one of the most effective ways for households to reduce both their energy use and carbon emissions.10 According to the Energy Saving Trust, replacing an A-rated gas boiler with a standard air source heat pump in an average three-bedroom semi-detached home can reduce a household’s carbon footprint by around 13.4%.11
A customer switching from a highly efficient 94% gas boiler to an air source heat pump could save on average £234 per year with EDF’s Heat Pump Tracker Tariff, compared with the current single-rate price cap tariff.12
EDF’s Heat Pump Tracker tariff offers six hours of discounted zero carbon electricity every day, all year round, with the assurance of no exit fees or tie-ins.
Save with Zero Carbon Energy
Steve, an EDF customer from Somerset, has already made the switch and says replacing his oil powered heating and hot water system with a heat pump was “the best thing he did”. Alongside his installation of a heat pump, he paired it with a substantial solar panel installation, making his home low-carbon.
He said: “Our home was previously heated by oil, so we wanted a more efficient and predictable energy solution. I’m now making substantial savings when accounting for the export from solar generation offsetting against the cost of running our heat pump. We wanted to create a house that was self-sufficient, and that’s exactly what we’ve ended up doing!”
Joe Souto, Director of Retail at EDF, said: “With rising energy costs and further increases to Ofgem’s price cap expected in January, many homeowners are looking for ways to save and make their homes more energy efficient, but are unsure where to start.
“Solar, batteries and heat pumps enable households to take control of their energy use and reduce their exposure to global fossil fuel markets. This also allows customers greater control over their energy costs in the long-term, providing additional security against the global energy market."

Frequently Asked Questions
When are the Black Friday offers available?
You must register your interest between 9:00am on 2 November 2026 and midnight on 29 November 2026. Registrations received outside of this period will not be eligible.
Who can take part in the promotion?
To qualify, you must:
- Be aged 18 or over
- Live in Great Britain (excluding Northern Ireland)
- Own the property where the solar panels or air source heat pump will be installed
- Register your interest within the promotional period
- Agree an installation date before the installation deadline
- Be purchasing the system for residential use
Commercial properties are not eligible.
When does my system need to be installed?
Solar installations must take place before 30 April 2027, and an installation date for heat pumps must be agreed before 23 April 2027 to remain eligible for the promotion.
How many offers can I claim?
The promotion is limited to one offer per person and applies to one solar or heat pump installation only.
Do solar panels still work on cloudy days?
Yes. Solar panels use daylight, not heat, to generate electricity. They produce the most power in direct sunshine, but they still work on cloudy or overcast days by using indirect light. They can also work very efficiently on bright, cold winter days, as cooler temperatures help electricity flow through the panels.
Will a heat pump keep my home warm during a UK winter?
Yes. A well-designed heat pump can keep your home warm through a cold UK winter. It runs for longer at a lower temperature than a gas boiler, keeping your home comfortably warm. The heat pumps we offer work in temperatures as low as -25°C.

7 Savings based on October 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 (2,500 kWh consumption with Standard electricity meter) would pay £858 per year for electricity based on October 2026 energy price cap rates.
A typical household (of 2-3 people and with 10-12 panels) with 2,500 kWh of solar generation and a battery with a capacity of 3kWh will pay £0 over a year, based on Empower Fixed Exclusive 12m & Export Exclusive 12m v3 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.
