Update from Horley Parish Council:
If you are not already aware, a full planning application has now been submitted by Elgin Energy for a massive Solar Power Station to be built north of Hanwell and straddling the Warwick Road. See map:

Part of the installation will overlook Horley along the skyline to the west of the Warwick Road and will be clearly visible as the slope of the site faces directly towards the village. The Parish Council will oppose this development, principally on the grounds of its detrimental visual impact not just from the village but from the surrounding countryside.
The full planning application consisting of many pages of studies and reports is available on the CDC planning website https://planningregister.cherwell.gov.uk/Planning/Display/25/00407/F#undefined. The reference number is 25/00407/F.
If you would like to make any comments on the application, you can do this via the CDC site using that reference number. The current closing date is 6th September 2025, and this will be your final chance to make your views known to Cherwell District Council.
