Early Bumblebee - Bombus Pratorum

We found this Bumblebee on the shed bathing in the evening sun and we think it is an Early Bumblebee which if we are right is the first time we have managed to id this species.  Photo not good due to its position and the strong sun but it did have a reddish tail and very yellow face and thorax which we think makes it a male.
Update, have now had it confirmed as a definite Early Bumblebee!
