Potentially with Binfield, Taplow, Wraysbury and Waltham leaving the Chilterns League, Chiltern will be merging with the Berks League. There would be a 'Prem' with the top five sides from the current Div 1s in each (so from Chiltern it would be Penn, Chalfont St Giles, Harpsden presumably and a couple of others as we are losing Taplow, Wraysbury and Binfield from last seasons top five), and regional leagues below with promotion for the sides that win each of the regional structures under it, so two relegated from ten team 'prem' and one promoted from each regional divisional structure. Or at least that's my understanding of it.
Doesn't matter to me though, so long as I'm playing I'm happy. And I'm back in Brighton full time next year on teacher training so will be playing at the lovely Firle CC rather than Chalfont St Giles.
