“Before we built EV chargers, we lived the same journey. We asked the same questions, faced the same challenges, and searched for better solutions. That’s why we created chargers designed with care, innovation, and purpose.”

Mandy & David Simpson

The Founders

The story so far...

Back in 2016, David and Mandy Simpson co-founded Andersen EV, helping to redefine what EV charging could be. After leaving in 2020, they swapped city life in London for the Cotswolds and launched their next venture, Simpson & Partners. Drawing on years of hard-won experience, they set out to build energy products that think faster, work smarter, and are built to last. Not designed by committee, and certainly not by accountants. This is innovation with heart.
