Residential solar / Watford
Residential solar in Watford.
Watford ranges from Victorian terraces near the town centre to the larger houses around Cassiobury Park and Nascot. REX surveys, designs and installs residential solar and battery storage across Watford and neighbouring Hertfordshire, starting with your roof and your bills.
Your Watford project
Start with what the property needs.
The useful result is a system you understand: how it fits, what it is expected to generate and where a battery may help.
Roof first, estimate second
The survey decides what is usable before any figure is given.
Battery if it pays its way
We compare storage against your spare generation and say so honestly.
Changes to the house included
Extensions and loft rooms are built into the layout.
A plan for the work itself
Access, scaffold and cable routes are agreed in advance.
Clear figures
Every estimate comes with its assumptions.
Local considerations
A closer look at Watford.
Terraces, semis and larger homes
Smaller terraced roofs reward careful layout. Larger houses around Cassiobury Park give more choice, and the question shifts from space to how much you will actually use. Both need a survey, not a guess.
Hills, trees and aspect
Watford has gentle slopes and a lot of mature trees. Orientation and shade vary from road to road, so we study them before estimating generation.
Why REX
From the survey to a clear proposal.
Send your address, a recent electricity bill or usage summary and a few roof photos. We will review the roof and discuss a layout and battery. The proposal sets out the equipment, expected generation, access and the work included.
Before you decide
Solar questions in Watford.
Do you cover all of Watford?
We survey and install across Watford and the nearby Hertfordshire towns. Send your postcode to confirm.
Can solar work on a terraced house?
Often yes, depending on orientation and shade. We show how many panels fit first.
Do I need planning permission?
Most homes can fit solar without it, but listed buildings and designated areas have extra rules.
Should I add a battery?
Consider it if most of your use is in the evening. We compare the options for you.
Is my street in a conservation area?
Watford Borough Council has a Nascot Conservation Area and others. A conservation area does not automatically rule out solar, but check your address with the council first. REX can advise on roof options.

Solar in a conservation area?
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.
