The offer

Our Sandford Hydro Share Offer remains open until 31 May 2017 to new and existing investors, with a target raise of £380,000 or more. Invest from £250, with returns to you forecast as 5%, based on RPI +3%.

More about the share offer & how to invest!


Investors in Sandford Hydro are helping 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 and 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. The three massive Archimedes screws have now arrived!


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:


  • 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 £1,000 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. This time, we have re-opened just our Sandford Hydro share class for a limited period as this project is nearing completion in the summer of 2017. Aside from the deadlines for investment shown in this document and the target equity raise table on p.13, all other information in this document is still applicable for our 2017 Sandford Hydro share offer -- please read the brief update we have put together to explain!

We have decided to keep the share offer open until the target date of 31 May, even if we reach the target before then. It is better both for existing shareholders and community benefit to have more community equity in the scheme and to be able to replace some of our long-term debt.

Note that the Solar PV 2016 share class is now closed, as all installations are up and running, and will not re-open for investment.
