How Blue Plaque Schemes Started

Founded in 1866 London’s Blue Plaque Scheme is the oldest scheme of its kind in the world. It erected the first two plaques in 1867. The first commemorating the poet Lord Byron and the second commemorating Napoleon III in Westminster. Blue plaques have played an important role in the history of the conservation movement ever since.

English Heritage took over the London scheme in 1986 and has run it along similar lines to its predecessors ever since. The first plaque it erected, in that year, commemorated the painter Oskar Kokoschka at Eyre Court on Finchley Road. Since then English Heritage has erected over 360 plaques, bringing the total across London to more than 900. A Blue Plaques Panel advises on the selection of individuals and brings a range of expertise to each case.

Due to the scheme’s success, it has spurred on the development of similar schemes across London and around the UK – all of whom have adopted their own style families. If you’d like to commemorate an important event, individual or location please contact us to discuss your plaque ideas.

Design service

From the first enquiry, Leander will help with design, choice of materials, colours, languages, grammar and fixings. Every plaque or sign produced, is first drawn to scale giving the customer the opportunity to request changes or simply approve the layout.

The range of signage and materials is suitable for almost any environment – from seaside promenades, railway stations, nature reserves right through to company offices.

Over the years, many aspects of the work have changed with the advent of computer design, laser etching, waterjet cutting, but old crafts such as hand-carving in clay and manual lettering are still practised every day. The company’s dedicated team will work with clients to produce designs that comply with current regulations.

Where should a Blue Plaque be installed?

Blue Plaques are generally placed in a readable location on the wall of a building to commemorate a historic event, notable person, or provide building information. The plaque size, distance from public & the information being displayed all impact the size of the text used. We offer a range of fixings (including bespoke options) for our plaques – the choice of which is related to listed building restrictions, type of surface being attached to etc.


As a primary manufacturer, we maintain long-term records of all the cast aluminium blue plaques we make and also offer an installation service and a refurbishment service for old plaques in need of some t.l.c.

All the high-silicon aluminium used in our plaques is 100% recycled metal, reducing the environmental impact of our castings.
