Firstly, as you are in the south east, have you used any of the contaminated fuel that Tesco and Morrison were selling? If so, the likelyhood is that your catalytic convertor has been damaged as a consequence of the silicon contamination which damages the MAP sensor and in turn the cat. You need to advise them that this has happened by going on their website or email . It would be handy to have a receipt for the fuel purchased on the effected dates which were around the last week of February and first week of March. Tesco are committed to repairing all damage sustained because of this contamination. I would imagine that Morrisons are also.

The next thing to consider is whether the car has been serviced correctly and whether it has indicated any fuel faults such as poor consumption figures which could mean that the car has been running rich all the time (or part of) without you realising it.

Another thing to consider is if it has ever been 'bottomed'. This can break the ceramics inside the cat and cause poor performance from it.

If none of these apply to your car, you should email Renault Customer Services and ask them what life expectancy a catalytic convertor should have. Try mailing explaing to him that the car has only done 20,000 miles and is only 4 years old. Of course you also need to ask them if they are prepared to replace it foryou if it turns out to have been defective, especially if the car has had its two-year servicing despite the low mileage.

Has the garage said what is actually wrong with the cat? Are you sure the problem won't clear itself if you give it a good (high revving) run on the motorway?

If you read the posts above yours and follow the links that have been given to others, you may well be able to make a considerable saving; but do try the other avenues first.

I wish you well.
