We don't know the price of a Bafang Max motor set. Or do we Woosh? There is some extra cost in the frame but that disappears with volume sales. And the big item, as on all bikes, is the battery, I think the Max would be happiest married to a 15 or 17 Ah 36 V or an 11.6 Ah 48 V.
Your cycle to work scheme doesn't take into account pedelecs, it is designed for bicycles. This has lead to an artificial (IMHO) £1000 barrier on pedelec prices, a limit at £1500 or £1750 would be more realistic for a pedelec to be used for riding to work every day. A £1500 bafang Max powered bike with decent components would not be overpriced.
