Meet the team

Here come the men in black, a team of experienced solar energy specialists who complement one another's skills. 

We work together to provide you with the best professional advice and solar energy solution for your home or business. Our objective is to show you how to maximise your use of the technology, drive down your bills and reduce your carbon footprint.

We do it with a smile on our faces because we enjoy what we do and we know that it makes a positive difference. It all adds up to a fast, friendly and efficient service that guarantees reliable results.

Guy Hewitt

Founder & Managing Director

Driven by the desire to deliver affordable solar energy solutions to homes and businesses alike, Guy qualified as a Domestic & Commercial Energy Surveyor and set up Treadlighter in 2007. With 30 years experience in business development and management he has helped expand a number of businesses throughout the UK & EMEA. Married with two children he’s also a keen golfer, skier and enjoys mountain biking. With interests like that no wonder he’s keen on energy efficiency!

Peter Cross

Technical Director

As an engineering graduate, Peter has an abiding interest in all forms of technology. His first novel, ‘The Warning’, a thriller based around climate change and the fact that it might easily be worse than we have imagined, compelled him to ‘do something useful’ rather than watch from the sidelines. Away from work, Peter is married with two children. Since rowing for Cambridge in the 1979 Boat Race, he keeps himself supremely fit as a Water Polo player, Triathlete and Mountain biker. He’s the only person we know who can eat as many chocolate biscuits as he likes!

Rupert Baker

Senior Systems Designer

Rupert is passionate about reducing CO2 emissions and has spent the last nine years delivering solar energy solutions for urban homes and businesses. Having designed the methodology used to rate and offer individually tailored solutions to Al Gore’s London staff and waste to energy systems for blocks of flats and community projects, he won contracts with University College London to quantify and advise on carbon reduction strategies. Rupert is married with four children. It’s a wonder he finds the energy to cycle everywhere

Sally Nolan

Accounts Controller

As a fully qualified Chartered Accountant Sally takes care of ensuring that our books balance and everyone is paid on time. Keeping friendly with Sally is to be recommended! Having worked in practice with a top 10 firm her experience is put to very good use. Away from Sage, she has a keen interest in tennis, hill walking, gardening and book-binding. No wonder our books look so tidy!
