"Sonny did two pieces of work for me — firstly an EV charger, and after impressing me with the tidiness of the install and quality of service, I asked him back for a solar and battery install. He was flexible, communicative, tidy, and reliable, and all elements of the system work perfectly. I'm a Chartered engineer with a long background in energy, and his competence and honesty was appreciated."

Common Questions

How much do solar panels cost?

A typical home system (4–6kW) ranges from £5,000–£9,000 depending on size and roof type. We provide a detailed, no-obligation quote after a free home survey.

How long does installation take?

Most residential installations are completed in a single day. Larger or more complex systems may take two days.

Will solar panels work on my roof?

Most roofs are suitable. South, south-east, and south-west facing roofs perform best, but east and west-facing roofs can still generate significant savings. We assess this during your free survey.

What is the Smart Export Guarantee (SEG)?

The SEG pays you for surplus electricity you export back to the grid. With MCS certification from Sun Key Energy, you are eligible to apply to any SEG-licensed energy supplier.

Do I need planning permission?

In most cases, solar panels fall under permitted development and do not require planning permission. We advise on any exceptions during your survey.
