Founded over 40 years ago by Michael Stewardson, a methodical and ethically strong electrician who continues to inspire the company to remain true to our ethos of always putting standards above all other aspects. These days the company is run by his son Edward who has developed the company to achieve UKAS BSI ISO 9001: 2015 certification and continues to expand the Triangle brand to become an industry leader whilst keeping the small family personality that our staff and clients equally value. Triangle is a maintenance/installation company adding value to Estate/Property Portfolios, FM companies, Hotels, Restaurants, Bars, Independent landlords, Developers, Surveyors, Builders and Homeowners in and around Greater London and throughout the U.K. We specialise in (PPM) planned and preventative maintenance, LED lighting upgrades and LV distribution upgrades. Triangle are very enthusiastic to take on a challenge and have installed Radar Towers in Norway and commissioned conference suites in Saudi Arabia.
