Introducing On Site Generation

On Site Generation is a Scottish renewable energy  company, set up to help save energy in our homes, businesses and communities. 

We are independent energy consultants and MCS accredited renewable energy installers, Green Deal assessors and training providers.

Founded in 2008, we have developed a reputation for design and installation quality, attention to detail and excellent service. We are passionate about reducing energy consumption, caring for the environment and supporting and advising our clients.

Please have a look through the installation, consultancy, and training pages of our web site and contact us to:

  • find out how you can save energy and reduce your bills;
  • look into the renewables that would work for your existing home, extension or new build;
  • access financial support including the Renewable Heat Incentive, Feed in Tariff and Scottish Government interest free loans for domestic and commercial renewables.

Contact Richard Witney in Roslin, Midlothian, or Jason Leon in Ullapool, Wester Ross to arrange an installation quotation, Green Deal Assessment, or discuss your consultancy, or training requirement.


Have you had a Green Deal Assessment yet? 

Contact us to arrange a Green Deal Assessment. Getting a Green Deal Assessment carried out is the easiest way to have a professional energy review of your home and help you decide on the energy saving and renewable energy improvements and how much they are likely to save. A Green Deal Assessment will allow you to access Government support schemes and Green Deal finance for insulation and other improvements, Home Energy Scotland Renewable Energy interest free loans, and Renewable Heat Incentive (RHI), or Feed in Tariff (FiT) for renewables. Assessments are carried out by Richard in the SE of Scotland and Jason in the West and North Highlands and Western Isles.  

Find out how solar PV is a great investment, on roof or ground mounted

If your roof is unsuitable for solar panels, or you have space nearby, we have developed a flexible, low carbon, ground mounted system suitable for all locations.

On Site Generation has teamed up with an architect and sawmill to create a sturdy ground frame design which will optimize output with no need for concrete foundations or steelwork.

Built from local Larch and Sitka Spruce, the panels sit into timber frames, mounted on posts and ballasted to complete the rigid, windproof structure.

Contact Jason in Ullapool, or Richard in Roslin for further information.
