Neil Spiers
Director | Sales
Neil’s work life began in a butcher's shop, but it didn’t take long before he was slicing his way into the world of market trading, and he's been charming people ever since. He kicked off at Spectrum as a self-employed driver, delivering windows to building sites, before officially joining full-time as a trainee estimator. Since then, he’s learned how to use a computer (big achievement, apparently), become a window-spec guru, and then smoothly transitioned into sales.
When he’s not dazzling us with his random facts, Neil loves spoiling friends and family with meals out and hunting for his next luxurious low-mileage car.

Since joining Spectrum in 2017 in technical sales, Dave’s confidence, expertise, and approachable nature have made him someone the entire team love working with and learning from.
