Hi I checked UK suppliers for this chip and all seeem to only do it on special order with delivery in December
One supplier is https://uk.farnell.com/c/semiconductors-ics/clock-timing-frequency-management/real-time-clocks?st=ds12c887

If you are handy with a soldering iron and have an etcing tool you could try adding an external battery to the chip as per this link

Don't be tempted to buy cheap pulled chips as the internal battery lasts around 10 years , so pulled chips you won't know how long it has been since manufacture.
