After some thinking I believe we will self source and have installed a Vaiilant EcoTecPlus 428 or 438 depending upon what the house needs and gives us overhead for things in the future pipeline like a Conservatory which is now on the 'Do Soon' list.
BG's prices have come down a lot in the last 12 months, but they won't offer what I want. Their loss is someone elses gain..
