The normal on-the-gate price is £10/person. However these can be pre-booked for £5 each on the Farm Energy Event official website until lunchtime on Friday 21 November if you want to have the tickets posted to you.
You can still book them until 10am on Monday 24 November, in which case they will be held on the gate for you.
The Farm Energy Event is the first event of its kind and is focussed both on saving energy and generating it yourself. There will be a full set of seminars as well as technical exhibits from manufacturers and advisory organisations.
