The BBC is looking for people in Harold Hill to take part in a film.
The producers from The One Show are making a four-minute film called The Day Britain Changed, which will look at important events that have changed the country.
The film goes out at 7pm every weekday.
They will be looking at the day that Margaret Thatcher introduced the Right to Buy, allowing people in council houses to buy their own homes.
The film will look at the benefits for several million people who became homeowners, and the difficulty for council in replacing the stock of social housing.
They have BBC footage of the time when Margaret Thatcher visited Harold Hill when the scheme started.
Show producers want to track down people from Harold Hill who bought their council home using the scheme in the 80s and find out how it affected their life.
They will be filming in the area with presenter Arthur Smith on April 12. Anyone who would like to take part can email Kieran McCarthy at Kieran@reallife.co.uk.
