About us

Sigma Electrics has an enviable reputation for quality repairs all over the North West for over forty years.

Sigma Electrics Ltd was purchased from the previous owner in 2000 by Gerry Armstrong. Gerry is a professional and manufacturer trained microwave technician with over thirty years experience in the sector.


In 2010 the company relocated to our current repair workshop at the Deeside Enterprise Centre in Shotton where there is plenty of free customer parking right outside our rear workshop door.


We are a recommended repair service facility for, and work in partnership with Panasonic, Sharp, Smeg and Sanyo. For these companies we carry out free of charge warranty work subject to their terms and conditions. We can however, repair any make or model of microwave oven including combination ovens and high end built-in appliances from the likes of Neff, Bosch, Siemens, Smeg.
