John Macdonald-Brown


"What we are seeing now as regards current and future legislation and policy-making is a very clear sign of where the agenda is being driven"

John managed commercial property funds from 1999 to 2009, at Ashtenne Holdings and subsequently at Spitfire Estates.  In this period John managed investment from AXA REIM, BlackRock and Lasalle IM.  

“The sustainability agenda has been the elephant in the room for many commercial property owners. What we are seeing now as regards current and future legislation and policy-making is a very clear sign of where the agenda is being driven. 

Planning requirements, 2018 minimum EPC requirements, 2019 zero-carbon development and the CRC regime to name but three….it is incumbent on property owners to introduce measures to improve building performance both in terms of reducing energy usage but also in finding ways to generate renewable energy on-site, it is going to be much more cost effective in the long run for those that take decisions now than it will be for those have changed forced up on them in later years.”

John set up Syzygy in 2009 aiming to help bridge the two worlds of renewable energy and commercial real estate.  Providing practical advice and to deliver well thought out and relevant renewable energy solutuions to property owners and occupiers.

Away from work John sails when he can, plays cricket, and occasionally golf.  In the winter, he can be found at most London Scottish home games, as a retired 1st XV player he is happy to bore the young athletes with advice on what it was like in his day!

John is married to Anna and they have two children, Tommy and Kitty.

Neil Sinclair


"Not being a contractor nor being wedded to any technologies really does allow us to deliver the optimum renewable generation solution for our clients"

Neil worked for 14 years at various financial institutions in London trading Emerging and European equities. His interests however lay elsewhere within renewable energy so in 2008/9 he completed a Masters at London business school and went on to set up and run a renewable energy contracting business, which he sold in 2011 prior to joining Syzygy. Neil brings practical experience in several of the major technologies as well as financial know how.

Away from work Neil loves to golf, ski and occasionally play tennis.
Neil is married to Bryony and they have three children, Cammy, Alex & Lochlan. He hopes all his boys play rugby for Scotland but if they fail to make the cut, the good news is they are eligible to play for England.
