EDF Active Deals, Sales & Codes in August, 2026

EDF is one of the UK’s ‘big six’ energy suppliers and a subsidiary of the French multinational utility company, Électricité de France [[3]]. As the largest generator of zero-carbon electricity in Great Britain, it operates a substantial network of nuclear power stations and wind farms. The company supplies gas and electricity to millions of British homes and businesses, alongside public sector organisations like the NHS and Royal Mail.

Beyond standard fixed and variable gas and electricity tariffs, EDF has expanded heavily into home energy solutions. Customers can invest in renewable technology, with solar panel arrays and MCS-certified air-source heat pumps available directly through the company [[26]]. They also offer specialised electric vehicle (EV) tariffs, such as the GoElectric Overnight plan, which provides significantly reduced off-peak rates for charging vehicles at home between 11pm and 6am [[11]].

EDF focuses heavily on rewarding flexible energy use. Their Sunday Saver challenge allows customers with smart meters to earn free electricity on weekends simply by shifting their power consumption away from weekday peak hours [[7]]. Additionally, the EDF app and online account portal make managing Direct Debits, submitting meter readings, and tracking daily usage incredibly straightforward.

Combining these greener, smarter home energy options with the switching deals and gift card offers below is a smart way to keep your household running efficiently without overspending.

When is the best time to switch my energy tariff? We usually advise keeping an eye on your fixed-term contract’s end date, as suppliers typically notify you a few weeks before it rolls onto a more expensive out-of-contract variable rate. Switching a month before your deal expires locks in better pricing. If you are an EV owner, look out for seasonal adjustments to off-peak windows; EDF recently extended their overnight cheap charging rates to run for seven hours from 11pm to 6am [[18]].

Which EDF tariff makes sense for an electric vehicle? If you charge at home, standard variable tariffs will eat into your budget quickly. We strongly recommend looking at dedicated EV plans like the GoElectric Overnight tariff, which drops the rate to around 6.49p per kWh during off-peak hours [[13]]. The trade-off is that your daytime rate for general household use might be slightly higher, so it only really works if you can shift the bulk of your heavy appliance usage and car charging to the night-time window.

Can I get extra perks if I’m a teacher or recent graduate? Yes, EDF runs targeted loyalty schemes that aren’t always advertised on the main homepage. Graduates and teachers can often claim bonus gift cards—sometimes up to £50—when taking on a new fuel tariff. You will normally need to verify your status through a third-party platform during the online quote, so have your university alumni email or professional ID ready before you start the application.

What happens to my solar or heat pump installation if I move? Home improvement tech is tied to the property. If you move, the solar panels or air-source heat pump stay with the building. However, if you are still paying off the finance plan for the installation, you must contact EDF to either settle the remaining balance early or arrange for the new homeowner to take over the repayment agreement.
