After Doris Hollamby put the house up for sale, an anonymous benefactor purchased it and donated it to The National Trust, who completed the purchase in 2003, with the Friends of Red House continuing to organise tours. Contributions from the William Morris Society and Bexley Council also aided the Trust in purchasing the building. It has since performed further restoration and research to restore the house as much as possible to its original condition. The house is open to the public, but not every day; guided tours must be advance-booked and unguided visits are available for limited periods. There is a tea room with a gift shop.
