The new timings will commence on Wednesday, October 1, to reflect shorter daylight hours and reduced visitor numbers later in the day.
The centres open at 9 am and close at 6 pm, but come next month, they will shut at 4 pm.
This will remain until March 31, 2026, when the clocks go forward.
Cllr Carl Jackson, Cabinet Member for Environment, Climate Change & Waste, said: “As the evenings get darker, our Household Recycling Centres start to receive fewer visitors after 4 pm, so we will continue with our usual policy of opening the centres from 9 am to 4 pm over the winter.
“This helps Buckinghamshire Council manage its resources efficiently while still providing the service which residents expect.
“I encourage residents to plan their visits and check the website before setting off.
“Don’t forget, if you have items in good condition, such as furniture, bikes, or garden equipment, you can donate them at any Household Recycling Centre for charity reuse.
“Those items are sold through South Bucks Hospice reuse shops, helping reduce waste and support a great cause.”

1. Amersham
2. Aston Clinton
3. Aylesbury
4. Beaconsfield
5. Bledlow Ridge
6. Burnham
