Thank you everyone for your replies, it has certainly given me a sigh of relief, really appreciate it. Wishing everyone a great week.

Hello everyone, I have recently moved into a 1960's mid-terraced property. I had a full survey done at time of purchase and nothing came back of any concern. I went into the loft for the first time and spotted that some brickwork is loose and missing on the party wall on one side of the property - as identified in the attached pictures. I was wondering if anyone can tell me if this is something to be concerned about and could pontentially become an issue over time? Everything else in the loft looks to be in good order, such as the timber supports and i cannot identify any cracking along chimney breasts or other walls. Any help would be greatly appreciated, unfortunatley I do not have a great deal of knowlege in this area. many thanks,
