Assess whether the compost is ready to use in the garden. If it is brown, looks like bought compost but maybe with a few twiggy bits then it is good to use.
If decomposing plant material and peelings can be seen then leave it for longer.
Well rotted garden compost or leaf mould*
Large garden sieve
* If compost from the heap is not ready to use, buy some bagged multi-purpose, peat free compost which is already rotted down.
