Will Bulb be part of the SEG scheme and if so when will they allow customers to enrol? One reason I ask is because the VAT on PV panels goes from 5% up to 20% in October. If Bulb does not come onto the scheme until January 2020 will it be possible to buy the panels before and still be eligible?

on your first question:
on the 2nd question, my understanding is that panels fitted before Jan 2020 will be eligible for SEG provided they don’t also qualify for FIT.
