There are big variations in the time it takes to approve new EV chargers, solar panels and heat pumps.
You need approval to make sure your local electricity network can support a new connection. Some areas may require a grid upgrade before you can go ahead.
Why must we wait for clean energy approval?
Approval times for clean energy solutions can range between one to 45 days, depending on where you live. This is because the Distribution Network Operators (DNOs), who manage the process, have different approaches. The result is a ‘postcode lottery’ where some homes can go ahead in a few days, while others wait for weeks.
Who’s waiting the longest?
A recent study shows that homeowners in the North of England and Scotland must wait the longest, especially for solar panel installations. In other areas, approvals can take just one week.
As costs for solar panels fall and demand for clean home energy solutions increases this is becoming a big problem. For example, one provider received over 200,000 enquiries for heat pumps last year alone. Delays affect national Net Zero targets, despite the government’s claim to be ‘sprinting to clean, homegrown energy’.
What’s the process to approve clean energy installations for my home?
Even following recent government announcements, you may still need planning permission, depending on your property and installation, so always check. You should also check your home insurance covers the installation; you might need to contact your insurer. Financial support is available, but you may have to apply in advance.
You are responsible for the compliance of your installation, so it’s important to work with someone registered as a ‘competent person’. They can often certify their own work on completion.
When you’re ready to go ahead, they can advise whether you must register with your DNO. If you need to apply to connect, your contractor must submit and Engineering Recommendation (EREC). You must then wait for approval or to find out about required amendments. After installation you must confirm your contractor has notified your DNO. You will then receive a Completion Certificate. For concealed installations it’s a good idea to keep photos of the installation process.
After completing your clean energy installation
Under the Microgeneration Certification Scheme (MCS) your installer should register your system within 10 working days. You may also want a new Energy Performance Certificate (EPC) to update the energy efficiency rating of your property. An EPC inspector will need your photographs to include any concealed work in your property’s energy rating. If you’re a landlord or applying for some government schemes, you’ll need a new EPC.
Make sure your installer explains how your system and its controls work and provides manuals on how to use it.
