Who we are

Next Gen Energy

Next Gen Energy specialise in the installation of renewable energy systems. Owners William Brannon and Alexander Almack have over 32 years of combined experience in the electrical industry, ranging from domestic to heavy industry.

After the successful operation of two electrical contracting companies, we set our focus to the future with renewable energy. We have a passion for building a sustainable world; one solar panel at a time.


You know you're in safe hands with Next Gen Energy. We are MCS accredited Solar PV installers, NIC EIC Approved Contractors, and members of the RECC and TrustMark. All of our installers are fully qualified, 18th edition trained electricians with BPEC Installation and maintenance of Solar PV qualification.



Step 01

We do not employ sales people and no salesperson will ever visit your home.

To discuss your requirements in more detail please complete the enquiry form below or call.

Get in touch


Remote Assessment Quotation

Step 02

On completion of your enquiry form, we aim to get back in touch within 24 hours. We will then ask you to provide us with more accurate information about the renewable service you require. An initial remote assessment quotation will then be sent over for you to consider.


Site Visit

Step 03

If the quotation is something that is of interest to you, we will then carry out a site survey to get the on-site credentials and run through any more questions or queries you may have and get an installation date in the diary.



Step 04

All of our site installations are carried out to the highest standard of workmanship. We aim to complete the installation seamlessly from arrival on site to commissioning and handover. A standard domestic installation usually takes 2-3days and a commercial/ industrial or agricultural project usually takes around 1-2 weeks to complete.
