thanks Margaret & Rainbow for your advice.

I have today been into Irvines on Church Street, very helpful guy there (the owner?).

He says can be done, but due to age of carpet (about 7 yrs), repair will still be visible, due to discolouration, prepared to do job for approx 50 quid, which I think is very reasonable.
Don't have any offcuts, discarded in garage clearout a couple of years ago, so repair patch will have to come from under fixed furniture, which is 'as new'.

Trying to persuade my wife that we should put this towards a new carpet instead!
(Not winning just yet!)

Thanks again to you all,

Regards
Gerard
