The Clapham Society: talks, walks and how to join
A volunteer charity since 1963: planning watchdog, green plaque maker, and host of free talks at the Omnibus on Clapham Common North Side.
By Clapham London Editorial
If you want to know who keeps an eye on planning applications, Common history and green plaques in Clapham, it is the Clapham Society. Talks are at the Omnibus on Clapham Common North Side, walks are booked through its website, and membership is £20 a year for an individual.
Who they are
The Society is a charity founded in 1963, funded by subscriptions and donations and run entirely by volunteers. It belongs to the London Forum of Civic and Amenity Societies. Its stated aim, as London Remembers puts it, is to improve quality of life in Clapham and strengthen its identity and sense of community. Its constitution covers Clapham regardless of local government boundaries, and membership is open to anyone who supports its purposes. In April 2026 the president was Sinclair Johnston and the vice-president was Julia Barfield.
More detail is on the Society’s about page.
What they actually do
- Planning and campaigning. The Society fights to protect Clapham’s character, conservation areas and historic or architecturally interesting buildings. It is consulted on planning and development proposals and, where needed, presents evidence at formal planning enquiries. It says local authorities have a statutory duty to consult it on planning and licensing matters, and it has a Planning Sub-committee.
- The Common. It works with the Clapham Common Management Advisory Committee. The April 2026 newsletter says the Common gets about 2 million visitors a year, and that the Society has the chance to tell more stories on public notices there, including new lecterns.
- Local History Group. It researches how the area developed, leads walks, issues publications and posts web articles on buildings and people.
- Newsletter. A regular newsletter covers local issues and events. It is hand-delivered in the Clapham area, and email delivery costs nothing extra.
The green plaques
In 2011 the Society started a scheme of green plaques for Clapham buildings that have changed use. The first went on Sycamore House, 4 Old Town, SW4 0JY, in August 2011. It is a house built in 1787. Others include the former Coroner’s Court at 43 Netherford Road and the former Plough Brewery on Wandsworth Road. The twelfth, unveiled on 15 June 2018, is on the Clapham Common Deep Shelter, now the base of Growing Underground.
The plaques are green aluminium, deliberately different from English Heritage blue ones. The full list is on the green plaques page.
Talks at the Omnibus
Talks are at the Omnibus Theatre, 1 Clapham Common North Side, SW4 0QW, a former Clapham library turned arts centre. They start at 7.30pm, last about 45 minutes and are followed by Q&A. The café bar opens at 6.30pm and stays open afterwards. Talks are free for members, and non-members are welcome and invited to donate.
Recent subjects have included artificial intelligence with Lord (Tim) Clement-Jones in April and Gasworks, the Lambeth arts organisation founded in 1994, in May. Earlier talks covered Van Gogh with Michael Glover and historic street nameplates. The remaining 2026 dates are all Mondays: 21 September, 19 October (the AGM) and 16 November. Details are at claphamsociety.com/events, and the dates are in the April 2026 newsletter.
Walks
The 2026 guided walks series opened for booking on 3 March. Past walks have ranged from Nightingale Lane’s medical history to a long Beating the Bounds of the parish boundary. Looking ahead, “Inspirational Women of Clapham” runs on Sunday 20 September at 11am and covers the northern part of the Common. Check the walk pages for meeting points and booking, as some walks are free but need a place reserved.
There are also self-guided routes. Walk 6, West Side, starts at Hightrees House on the corner of West Side and Nightingale Lane. Everything is listed on the walks page.
The Society also promotes the Lambeth Local History Forum leaflet of local walks. The 2025/26 edition listed more than 90, and it is free from Lambeth and Wandsworth libraries and the Omnibus.
