Identification Please

Good afternoon

Have been out today and have taken the enclosed photo.  I thought it was a Coal tit until getting it up on the computer to find the red/brown stripe above the eye.

Very shy and there were at least two of them keeping relatively close to each other.    Habitat - Deciduous tree area, close to expanse of water.

I have looked in RSPB pocket guide and also on-line but still can't be certain.  

Perhaps you can help please.  Thanks in advance

kind regards
