A branch of the Nationwide building society in Streatham has been closed to the public this week amid an allegation of a staff member testing positive for Covid-19.

The building society branch on Streatham High Road has reportedly been closed to customers for several days, and a source close to a staff member at the branch said they were told that was due to a positive Covid case among the staff.

Speaking anonymously with the Wandsworth Times, the person, who said they were a friend of a member of staff at the Streatham site, said:

"My understanding is that they've had several people reporting possible Covid infections... they had one member of staff getting pinged by the Covid-19 Track and Trace app.

"That person apparently reported to the manager that they had then tested positive for Covid-19.

"They've now done a compromise where the staff have to go in, but the doors are staying shut because there are only two members of staff in there.

"So staff travel there knowing that they may have possibly come into contact with a person who has got a positive Covid test."

The source added that the situation had been complicated because not all staff members on site had the Covid-19 Track and Trace app, allegedly, and so had not received advise from it to self-isolate.

The Wandsworth Times approached Nationwide for a comment on the situation, who said the building society's "priority" was "keeping members and colleagues safe".

The spokesperson who responded declined to address the assertion that the closure was related to Covid-19 but offered the following statement:

"Our priority is keeping members and colleagues safe, we remained open throughout the pandemic providing vital financial support to members.

"We follow health and safety guidelines and have robust measures in place in our branches and offices.

"It wouldn’t be right for us to comment on individual colleagues or branch situations, however we can confirm we are working towards re-opening Monday once we have looked at local resourcing options."
