Quick answer

West Sussex sits in the UKPN distribution area (different from Hampshire's SSEN), and we handle the G98/G99 application accordingly. From heritage Chichester to coastal Worthing, the county offers strong sun and a high-value owner-occupier market.

West Sussex marks the eastern side of our coverage, and an important distinction: properties here connect to the grid through UK Power Networks (UKPN), not SSEN. We handle the correct G98/G99 application for your postcode automatically.

From the Georgian streets and conservation areas of Chichester to the coastal towns of Bognor Regis, Littlehampton and Worthing, West Sussex blends heritage sensitivity with strong south-coast sun. We design discreet, all-black systems where heritage matters and high-output arrays where it does not.

Grants & export income

There's no single grant that pays for a typical West Sussex solar install, and we won't pretend otherwise — most owner-occupiers here won't qualify for one. Means-tested and property-condition schemes such as ECO4 and the Warm Homes Local Grant target lower-income or low-EPC households, and council-backed Solar Together group-buying rounds appear in some Sussex areas but come and go; we'll tell you honestly if you're eligible rather than build a quote around a grant you can't get. For the vast majority of homeowners the real ongoing earner is the Smart Export Guarantee (SEG): with an MCS-certified install and a smart export meter, your supplier pays you for the power you send back to the grid — as of 2026 leading tariffs pay roughly 15p–27p per kWh, though each supplier sets and changes its own rate, and you can hold your SEG tariff with a different supplier than your import one.

FAQ

Solar panels in West Sussex: FAQs

How much do solar panels cost in West Sussex?
A typical home system across West Sussex costs from around £5,500–£11,000 depending on size and battery storage, with 0% VAT on residential solar. ~1,100 kWh/kWp per year — a 4kW system generates around 4,100–4,400 kWh. Every quote is tailored to your roof after a free survey.
Which electricity network (DNO) covers West Sussex?
UKPN (UK Power Networks). We handle the full G98 (smaller systems) or G99 (batteries and larger arrays) connection application on your behalf.
Do you need planning permission for solar panels in West Sussex?
Most installs are permitted development; conservation areas and listed buildings need sensitive design. The main planning authorities here include Chichester District Council, Arun District Council, Worthing Borough Council, Horsham District Council. We advise per property and design discreet systems where required.
Which towns in West Sussex do you cover?
We install across West Sussex, including Chichester, Bognor Regis, Littlehampton, Worthing, Horsham, Crawley, Midhurst, Petworth. If your town isn't listed, just ask — we very likely cover it.
Which DNO covers West Sussex, and do you handle the grid application?
West Sussex sits in the UK Power Networks (UKPN) distribution area — not SSEN, which covers Hampshire and the Isle of Wight. We handle the connection either way: a solar-only system up to 3.68kW per phase is a G98 'connect and notify', where we simply notify UKPN after commissioning. Anything larger, or any system with battery storage or export, is a G99 — we submit that application to UKPN and get it approved before we install, so there are no surprises.
I live in a Chichester conservation area — do I need planning permission for solar?
Most domestic roof solar in England is Permitted Development, so no planning application is needed, provided panels don't project more than 200mm or sit above the highest part of the roof. The main exception that affects West Sussex is heritage: panels on a wall or roof fronting a highway in a conservation area may need a planning application, and any listed building needs Listed Building Consent. Chichester District Council and the South Downs National Park Authority take this seriously, so we design discreet, all-black, rear-slope systems for heritage settings and advise on consent before you commit.
How much does solar cost in West Sussex, and what does the price depend on?
Our packages start from £4,995 for an 8-panel solar-only system (DMEGC 450W panels and a Fox inverter, bird-protection mesh included), and every price is a 'from' figure subject to a survey. Adding storage moves you up the range — from £6,995 with a Fox ESS battery, from £8,418 for EcoFlow/Sigenergy, and from £12,920 for a Tesla Powerwall 3 setup. West Sussex's high-value housing means many homeowners opt for battery packages, but the right system depends on your roof, usage and budget — we'll quote honestly, never with a single guaranteed number.
Is West Sussex actually sunny enough for solar to be worthwhile?
Yes — the West Sussex coast enjoys some of the UK's highest irradiance at around 1,100 kWh/kWp per year. In practice a well-sited 4kW south-facing array here generates roughly 4,100–4,400 kWh a year; an east- or west-facing roof produces about 15–20% less, in the region of 3,300–3,700 kWh. Even without a perfect south aspect, the strong south-coast sun makes solar a sound investment across the county.
