Hi fort -
Stuart (isn31c) may well be correct in that it might be a bit early for some of the accommodation to be open for booking. That said, I have heard that some of the more isolated accommodation on National Trails (I.e. those that are on or very near route and which are in otherwise unpopulated spots - probably not something you could level at the Cotswold Way to be fair) get booked up several years in advance. Similarly, since the advent of the ‘staycation’ since the Covid epidemic I have a suspicion - without any concrete evidence I hasten to add - that the most prominent ‘Sherpa/packhorse’ companies are reserving some of the more desirable accommodation on or just off route on the more popular trails. I’m thinking The Coast to Coast, West Highland Way, and yes, The Cotswold Way.
A quick search for ‘Cotswold Way self guided holidays’ or similar will throw up quite a wide choice of companies, mainly the usual suspects, and as they are all competing with one another the prices, you’d expect to be much of a muchness, varying only by length of time you need and maybe level of accommodation. Macs, Mickledore, Brigantes, Contours, maybe Encounter for the Cotswolds Way, and some Cotswolds local specialists should all appear (with others, of course) and it’s a matter of deciding which best suits your requirements on all fronts.
I can say from personal experience this year that it’s not too early to start booking through these companies for the 2026 season as many are already booked up on popular trails for this year, unless, of course, you are set on booking independently, in which case you’ll just need to email a lot of the accommodations to establish what the facts actually are.
Hope you get sorted to your satisfaction!
Ian
