Plummer Electrical began life on 10th May 1960 as Plummer Bros.

Plummer was started in North Walsham by Charles Plummer who after being trained in the RAF during the Second World War had been an electrician with Bickerton & Sons. When Mr Jones, the Manager of Bickerton & Sons, decided to sell it, Charles bought it and set up his new company on New Road in North Walsham. While the contracting side of the business was initially the larger part, the retail side grew over the years, necessitating extensions to both front and rear of the purpose built premises, along with the conversion of the upstairs flat into another showroom, so that the huge range of white goods, lighting and more could be displayed for customers.

On the 4th May 2013, Plummer Bros electrical retailers and contractors closed the door at the New Road shop in North Walsham for the last time after almost 53 years of business.
Due to plans of ‘cutting down’ the decision was made to down size the business and sell the retail side of it and keep only the electrical contracting as Plummer Electrical which was based on Cornish Way in North Walsham.

In May 2016, Plummer Electrical was taken over by ADM Plumbing and Heating Ltd and now based in Reepham. Andy, Kevin & Chris continue to provide the same Plummer Electrical service to customers old and new.
