Our heritage
James Medlock — founding Lightplan in 1910
1910 The founding

Gas lamps & the spirit of the hare.

The Lightplan story begins with founder James Medlock, who traded his pedal-cycle for a motorcycle and sidecar and set out to supply Britain’s growing industries with the gas mantles, oils, mica, and glassware they needed to function. He embodied what he called “fast-moving factors of vision and courage” in a quickly evolving trade.

The business began in a modest two-storey warehouse in North London — a former stable rumoured to have sheltered Dick Turpin’s horse. From day one, success was built on tireless effort, sharp organising ability, and a foundational belief in integrity that remains a core value today.

Harold Medlock joins the business — 1919
1919 The family grows

Here comes Medlocks.

Joined by his engineer son Harold in 1919, the family purchased their first delivery van — emblazoned with the now-iconic slogan: “Here comes Medlocks.” The spirit of constant movement and adaptation kept the firm always one step ahead.

As electricity swept the nation, the Medlocks swiftly pivoted — from gas mantles to securing the agency for the revolutionary Columbia Radio Battery, ensuring they were always keeping pace with the technical shifts transforming British homes and industry.

Lightplan first dedicated showroom — 1958
1958 The pivot to design

From technical excellence to inspiring spaces.

In 1958 we opened our first spacious, dedicated showroom. This move transformed Medlock from North London’s “Promptest Factor” — a veritable treasure-house of electrical stock — into a destination where customers could experience shaded lamps and lighting in an inspiring, curated setting.

This pivot from technical electrical expertise to sophisticated visual design is the defining dual identity that characterises Lightplan today. We still hold the deep technical knowledge of the founders, now fused with the aesthetic mastery of modern lighting design.
