How often does sewage spill near Fishbourne?
The three monitored storm overflows within 1.5 km of a Fishbourne postcode spilled 74 times in 2025, for 1,034 hours in all, on the water companies' returns to the Environment Agency. The busiest was Chichester wastewater works, which empties into Chichester Harbour: 66 spills and 988 hours across its two outlets. In 2024, the monitored overflows within 1.5 km of a Fishbourne postcode spilled 133 times, for 1,990 hours. The Environment Agency put much of the fall across England down to an unusually dry 2025 after a particularly wet 2024. A storm overflow lets diluted sewage out into a river or the sea when heavy rain overloads the sewers. The counts use the Agency's method, in which the first 12 hours of a spill count as one and each 24 hours after that as another.

How clean is the water for swimming near Fishbourne?
Chichester Harbour itself is not a designated bathing water, so the Environment Agency does not test it for swimming or give it a rating. The nearest beach the Agency does rate is Bracklesham Bay, a median 9.2 km from Fishbourne's postcodes in a straight line, rated Excellent for 2025; next is Pagham, 9.8 km away and rated Good. A rating covers the last four summers of samples, not any one day, and new ratings come out each November. In the bathing season the Agency also issues a daily pollution risk forecast for Pagham. Storm overflow spills near Fishbourne are covered in the sewage answer on this page.
How energy efficient are homes in Fishbourne?
About the same as the area as a whole, on their energy performance certificates. Of the 838 homes in Fishbourne with a certificate on the government register, 53% are rated C or better, against 50% across the Chichester council area; the most common rating is C. Mains gas heats 91% of the 838 whose main fuel is recorded, and electricity 7%. Four have a heat pump. Of the 833 whose certificate records it, only 7% have no mains gas connection; 5 certificates do not say. 6% have solar panels, and eight have solar water heating. A certificate is only made when a home is sold, let or built, so homes that rarely change hands are missing, and an old one shows a home as it was then. Each home's latest certificate is used: issued between 2008 and 2026, half of them since 2017.
