ALAN ASTON:

As you haven't given any indication of how long this has been happening, it's difficult to say!
As per the post before yours, the transmitter is subject to Planned Engineering which may be the reason.

There has been quite variable weather related Tropospheric Ducting in recent days which can affect reception because of interference being received from more distant transmitters in Europe or the UK - not all multiplexes are necessarily affected.

You may normally have problems with co-channel interference on C25 but as you haven't given a full postcode, it's impossible to comment on that.

Just to add, if your aerial is pointing in a southerly direction, the Preseli transmitter may be receivable within its beamwidth, so you could try a manual tune of C42 for the SDN multiplex, but reception may be variable.
