Such approvals are needed to ensure that the local electricity network can support the new connection. If the network can't cope, a grid upgrade may be required. This process for clean technologies stands in stark contrast to the process for fossil-fuel alternatives, such as gas boilers, which don't require the same approvals.
Approval times for clean technologies can range between 1 to 45 days, depending on where in the country customers live, the new Octopus' data shows. The delays are caused by inconsistent processes among Distribution Network Operators, who manage installation approvals across different regions. This disparity has led to a 'postcode lottery' where some homes are green-lit for upgrades within a few days, while others are left waiting for weeks.
The data shows a clear North-South divide: customers in the North and Scotland are facing longer delays, especially for solar panel installations, while those in areas served by National Grid Electricity Distribution and UK Power Networks experience the shortest waits – averaging at 7 days for all technologies.
With inquiries for heat pumps increasing 144 percent in 2024 compared to the year before and costs for solar panels coming down to record lows, Octopus is calling for urgent action to streamline the approval process, and speed up the UK's push toward net zero.
“The UK's journey to net zero depends on millions of people being able to install clean technology in their homes” said Alex Schoch, Director of Electrification at Octopus Energy. "While some are getting these quickly and efficiently, current delays in the worst-hit regions risk leaving many customers in limbo while waiting for approvals that should take hours, not weeks. We're shining a light on the blockers and will continue to work with industry and networks to clear the way for faster, fairer access to clean energy tech."
