Havant sewage spills
The four monitored storm overflows within 1.5 km of a Havant postcode spilled 5 times in 2025, for 18 hours in all, on the water companies' returns to the Environment Agency. The busiest was the Budds Farm Havant storm overflow, which empties into Brockhampton Creek: 3 spills and 8 hours. In 2024, the monitored overflows within 1.5 km of a Havant postcode spilled 10 times, for 47 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.

Havant water quality for swimming
Havant has no designated bathing water of its own. The nearest beach the Agency does rate is Hayling Beachlands Central, a median 7.8 km from Havant's postcodes in a straight line, rated Excellent for 2025; next is Hayling Beachlands West, 7.9 km away and rated Excellent. A rating covers the last four summers of samples, not any one day, and new ratings come out once a year.
How energy efficient are homes in Havant?
About the same as the area as a whole, on their energy performance certificates. Of the 4,086 homes in Havant with a certificate on the government register, 51% are rated C or better, against 53% across the Havant council area; the most common rating is D. Mains gas heats 81% of the 4,086 whose main fuel is recorded, and electricity 18%. 123 have a heat pump. Of the 3,867 whose certificate records it, only 13% have no mains gas connection; 219 certificates do not say. 2% have solar panels, and 21 have solar water heating. 29% are flats or maisonettes. 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 2019.
