Step 1 of 3
What is your monthly electricity bill?
Roughly is fine. It tells us how much solar could do for your home.
Southampton homeowners
A saving worked out for your home.
A port city with Victorian terraces, 1930s suburbs and waterfront flats cannot be served by one package, so REST starts from your bill.
Panels and storage worth researching
NEXA panels from Eurener are warranted by the manufacturer for 30 years, with output covered separately for the same period. Tesla, Fox ESS, Growatt and Duracell storage is available if it suits.
Safeguards you can verify
Fitting follows MCS standards. Your deposit is insured through HIES. The savings are checked and cleared by EPVS before any fitting begins.
What it means at home
A way to cut future electricity purchases
Solar can contribute in every year that it generates usable power. A longer forecast puts that into context, next to the price of the system.
In the daytime
In the daytime, the panels can supply the house directly, meaning the grid supplies less.
In the evening
A battery stores some of the day's surplus so it can be used when the household is busiest, after the panels have stopped.
Once it has paid for itself
Once the payback point has passed, the electricity you generate and use is no longer something you buy. The forecast includes future costs, not just the savings.
What stands behind a quote
Credentials that can be checked.
Each of these can be confirmed without relying on REST.
Warranties on NEXA panels
Eurener, the manufacturer, warrants the panels and their performance for 30 years each, and REST supports you through any claim.
Four battery makers
Tesla, Fox ESS, Growatt and Duracell, with capacity matched to your evening usage.
Deposit cover
HIES, which is insurance-backed, protects the deposit you pay, up to the limits of its scheme.
Honest estimates
The EPVS calculation produces the savings figures, EPVS clears them before installation, and each is labelled as an estimate with its assumptions.
Solar in Southampton
Planning, grid and roofs in Southampton.
Three local points that may affect a Southampton installation.
Conservation areas, listed buildings and flats
Southampton has conservation areas, including parts of the Old Town, and listed buildings need consent. Waterfront and city-centre flats follow different rules from houses, so roof ownership matters. Outside those places, a house roof can normally be fitted with panels without applying.
Scottish and Southern Electricity Networks
Southampton homes sit on the Scottish and Southern Electricity Networks grid. REST handles the G98 or G99 paperwork, though the operator sets how quickly it replies.
Terraces, 1930s suburbs and coastal exposure
Victorian terraces, interwar semis and homes near the water each bring different roof space and wind exposure. The surveyor checks your own roof.

Common questions
Quick answers before you enquire
No, and asking creates no obligation.
Take your time with a proposal for Southampton. It shows:
- The assumptions behind each estimate
- Finance options, subject to status
- Panel warranty details
- How your deposit is protected through HIES
- Your panel layout
- Your price, confirmed after the free survey
Yes. Finance is available, including routes that need nothing upfront. Finance is subject to status and lender approval, and REST UK acts as a credit broker, not a lender.
Yes, before a firm price is given. A surveyor measures the roof, notes shade and inspects the wiring, free of charge.
It can be. After payback you keep using electricity from your own roof instead of buying it, and your proposal sets out when that is expected to start.
Treat it as a sensible first guess based on typical use. Once your roof and your consumption are known, the quote replaces the guess, though it is still an estimate.
No, but exposure to wind and salt air influences fixings and equipment, which the surveyor allows for.
Possibly. The roof's owner, usually the freeholder, has to agree, so ask about it before anything else.
They can add checks, and listed buildings need consent. Your council can tell you what applies to your street.
Yes, once you are on a Smart Export Guarantee tariff, though the rate is your supplier's choice.
