Energy retailer EdF is launching what it claims is Britain’s first electricity tariff that bundles together an off-peak discount, plus no standing charge or exit fee.

The new tariff, Empower Exclusive, is designed to spur yet more uptake of Britain’s estimated 1.2 million homes fitted with solar PV arrays.

Exclusively available to new customers who install a panels-plus battery bundle through EDF’s in-house installer, Contact Solar, the Empower Exclusive tariff is promoted as saving a standard home more than £800 per year against EdF’s standard variable tariff.

EdF is also offering £500 off a new panels-plus-battery installation to the promotion’s first 500 customers, and without any deposit before installation.

EdF bought Chorley-based Contact Solar earlier this year and has integrated it into its operations.  The supplier says more price & package deals related to home solar are in the offing.

This first deal helps customers charge their batteries overnight, providing three hours of discounted, zero carbon electricity for three hours starting at 1:00am.  By charging the battery more cheaply overnight, the discount helps householders reduce their reliance on external supply during peak hours.

With systems available for on average £8,500 for a typical 3-bedroom house, Contact Solar’s package offer includes 10 panels, a 5kW hybrid inverter and 5.32kWh battery, all installation and scaffolding costs, a 10-year battery and inverter warranty, a 25-year panel warranty, virtual and technical survey costs, and access to a system monitoring and performance app.

All combinations of solar and battery installs will also benefit from 0% VAT.

Tom Taylor, director at Contact Solar, said: “We’re delighted to now be a fully integrated part of EdF, bringing exceptional new benefits to customers such as this new exclusive energy bundle.

Philippe Commaret, EdF’s managing director of customers, added: “We know more and more people are looking for ways to save cash and carbon, which is why we’re pleased to bring this unique solar product bundle to the market.
