Richmond council said: "This year we have been working closely with the other South West London Boroughs and the local hospitals in the promotion of the campaign to provide HIV testing and ensured that our services are ready to provide the testing facilities for anyone who chooses to turn up for the HIV test.
“We will use this year's evaluation to improve the service provision in the coming year.”
As part of European HIV testing week in lead up to World Aids Day, Richmond will offer walk-in-appointments for HIV mouth-swab tests that give results in twenty minutes.
