You’ll be put up in a hotel if your Home Depot is over 90-mins travelling time from the training facility. I was in a hotel in Bristol (several hotels in the end). It’ll be for around 15/16-weeks Ish.
Strangely, one of my letters/emails from GWR said if I required accommodation to let them know, which I did. Probably worth bearing in mind if you are going to need accommodation, just in case. They will usually give you several weeks worth in a batch, and then you’ll have to remind them again that you’re running out of accommodation
