A system for your use, not a standard pack
We start from how your household uses power and work back to panels.
Edgware and Mill Hill sit at the north-west edge of Barnet, close to REX's office on Brent Street. Large interwar semis and detached houses are common here, with newer homes alongside. REX surveys, designs and installs residential solar and battery storage across HA8 and NW7.

The useful result is a system you understand: how it fits, what it is expected to generate and where a battery may help.
We start from how your household uses power and work back to panels.
Hips, valleys, dormers and side extensions cut into usable space. We measure what is left.
We compare battery capacity with your spare daytime power before suggesting one.
If a loft conversion or rear extension is coming, we plan around it so panels are not moved later.
Where the scaffold goes, where the inverter sits and how cables run are agreed in advance.
You see the assumptions behind every generation figure.

Many houses in Edgware and around Mill Hill Broadway are bigger than the average London home, and the roofs often have room for a worthwhile array. Larger houses also tend to have larger bills, which can make solar more relevant.
Mill Hill has an old village core around the Ridgeway and the school, and newer developments elsewhere. Newer roofs are often simpler to work with. Older properties need a condition check first.
Tell us the address, send an electricity bill or usage summary and a few roof photos. We will review the roof, propose a layout and discuss storage. The written proposal covers equipment, expected generation, access and the work included.
Not in itself. Each house is assessed on its roof and its position. If your property is in a designated area, that is checked first.
Usually, subject to the roof design and any warranty conditions. We review both at survey.
Your bills tell us how much you use and when. The usable roof tells us what is possible. The system sits between the two.
Yes. We survey and install across both.
Barnet Council has a Mill Hill Conservation Area, and Edgware and Stanmore have conservation areas under Harrow Council. A conservation area does not automatically rule out solar, but check with the council. REX can advise on roof options and layout.
Planning your solar installation
A conservation area does not automatically rule out solar. REX can advise on conservation matters and discuss roof options, with consent requirements confirmed by the council or relevant estate.
