Cam-belt change on Espace III (1998- 2003) is 70,000 miles. The car has a G8T turbo diesel engine. You may be asking about the newer Espace IV model.... not sure about that one. I'm sure your dealer will tell you (take a deep breath before they give you the cost!)
Although the service mileage is 70,000 it is quite safe to let it go to100,00 miles which apart from saving miles/money is easier to remember. It can cost between £200 and £300 and is not rocket science. However if you go to 140,000 you will break the belt. This will break cam followers and may bend valves. If you go that route expect to pay nearly £1000.
Incidentally every belt change it is a good idea to change the water pump at the same time. It will add only £50 to the bill and G8T turbos have a habit of having water pumps go about 150,000.
Later Espace 2.2 (mine is 2005) is supposed to have a cam-belt after 5 years. Mine has only done 29000 miles and my local - non Renault - garage says don't bother. Out of interest I checked with the Renault garage who quoted £710! With discount that would be £576. I don't think I will bother. Incidentally when our Fiat 2.8 motor home reached 5 years we were advised by the caravan magazine to get it done although, like the Espace, the mileage was low.
take it to a proper garage
how many miles before you have to change cambelt on Renault kangoo 1.5 dci van
At a garage, no way is this a home job
Which Renault do you have? I have a Espace 2.2 litre 1994 and had to take away the radiator and also take away the hoses for the AC (let the gas out). Make sure to put in new belts for the alternator and AC compressor when having the radiator away. Else to change the cam belt is the same as any over head cam, make sure the marks are aligned and put it back as it were.

72000 miles, 5 years
Take to garage as special tools required to lock cams and crank
YOU SHOULD CHANGE THE CAM BELT EVERY 30,000 MILES OR EVERY FIVE YEARS,WHICH EVER COMES FIRST.
If it's a Scenic model about £300+. If any other model alot
