The cathedral is exploring ways to increase income and reduce expenditure in a bid to safeguard the future of its ministry.
Costcutting measures are affecting spending on energy and staff, and parishioners are being asked to increase their giving.
The deficit stands at £81,000 and the Cathedral Dean and Chapter are
considering meeting the majority of this cost by downsizing the choir.
They predict that reducing the size of the choir would make a saving
of around £50,000.
The assistant organist, a choral scholar and five lay
clerks are all facing redundancy.
Cathedral officials are proposing to keep a budget that will be used
to pay adult choristers on an occasional basis to sing with boy
choristers on weekend services and special seasons like Advent and
Christmas.
A spokesperson for Llandaff Cathedral said, "It is with a very heavy
heart that we have taken the decision to put a number of roles in the
Cathedral at risk of redundancy. However, we have a duty to be financially responsible and cannot run
on a continuing deficit. We have considered all our options very
carefully and feel these plans are the best way forward to enable us to
save money while ensuring our choral tradition remains as good as it can
be, and our music ministry has a secure future."
