The offer

At the end of February 2017 we will re-open our Sandford Hydro Share Offer for a limited time, with a target raise of £380,000. The minimum investment is £250 and returns to you are forecast as 5%+, based on RPI +3%.



Investors in Sandford Lock Hydro will help return the Lasher Weir (between Sandford and Kennington on the Thames) to its historic role as a provider of clean energy. This hydro project will generate 1,600 MWh per year -- the equivalent demand of 450 homes, or most of Sandford. Construction on this project began in September 2016 is due to be completed in Summer 2017.

Through this community energy share offer, local residents and people from further afield have a chance to own part of this amazing hydro system, earn a good financial return, and make their money do good. 


Visit our Sandford Hydro Case Study to find out more about the project, or follow blow by blow construction updates here. Look out for the arrival of the three massive Archimedes screws in April!


As a social (rather than commercial) developer, we reinvest 100% of our own surplus revenue from our renewables projects, after costs and investor returns are paid, back into our renewable energy mission. Find out more about our vision for a 'people's energy system' in our Low Carbon Hub Community Energy Manifesto or visit our Projects page to see all the community energy and innovation projects we've already completed.


  • Internal rate of return (IRR) based on RPI+3% paid per annum until 2036. On current projections, this would give an IRR of 5% over the 20 year period.
  • Interest payments from the end of the second year of operation and 100% repayment of your initial investment progressively over 20 years, starting in year 4.
  • With the new Personal Saving Allowance (PSA) you may be able to earn up to £1000 in interest from your shares tax free.
  • All Members have the right to attend general meetings, and have one vote, regardless of how many shares they hold.
  • Shares can qualify for 100% relief under Business Relief for Inheritance Tax.

Our Share Offer Document

This document was created for our 2016 Share Offer which had two share classes: (1) Sandford Hydro and (2) Solar PV 2016. In February 2017 we will re-open our Sandford Hydro share class for a limited period. Aside from the deadlines for investment shown in this document, all other information in this document is still applicable for our 2017 Sandford Hydro share offer. 

Please note that the Solar PV 2016 share class is now closed and will not re-open for investment.
