Why a local West Sussex installer matters
West Sussex covers a wide range of property types — from rural properties around Petworth and Midhurst to suburban homes in Horsham and Crawley and coastal properties along the South. Each comes with its own roof geometry, grid connection requirements and planning considerations. The South Downs National Park, conservation areas and listed buildings all affect what is permitted — and working out that position before survey saves everyone time.
Omni3 is based in Pulborough, at the centre of West Sussex. Every installation is carried out by our own accredited engineers — we do not subcontract. That means direct communication throughout the project, consistent standards on every job, and a team that remains accountable after completion.
We have completed solar and battery storage installations across the county. The projects below are real — not generic case studies.

Planning and grid considerations specific to West Sussex
West Sussex has several planning designations and grid characteristics that affect solar installations. Understanding these before survey avoids delays and surprises later.
South Downs National Park
A significant portion of West Sussex falls within or adjacent to the South Downs National Park. In most cases, solar panels on a roof that is not visible from the highway (the principal elevation) remain permitted development. Panels on the principal elevation within the park may require planning permission. We check planning status for every property as part of the free survey.

Several West Sussex towns have designated conservation areas — including parts of Arundel, Chichester and Petworth. Solar on the principal elevation of a property within a conservation area is not permitted development and requires planning permission. Panels on a rear elevation or non-principal roof are generally permitted. We advise on this at survey stage.

Listed building consent is required before installing solar panels on any listed building — permitted development rights do not apply. West Sussex has a high concentration of listed properties, particularly in market towns and villages. If your property is listed or within the curtilage of a listed building, we will advise on the correct process before any survey work begins.

West Sussex falls under UK Power Networks (UKPN) for grid connection. Solar systems up to 3.68 kW per phase connect via a G98 notification submitted after installation. Systems above 3.68 kW per phase require a G99 application submitted before installation begins. Omni3 manages the DNO process on behalf of every customer.
