You Can't Beat Peat for Compost

The two best buy composes as determined by independent laboratory test are:

Best for raising young plants: J Arthur Bower’s Traditional All-Purpose Compost (When buying, don’t confuse it with J Arthur Bower’s Multipurpose or Multipurpose with added John Innes as both did badly in the trials - just make sure the word "Multipurpose" isn't on the packet.

Best for containers was: Verve Grow Your Own Growing Bag.  This cost as little as 7p per litre and is available from B&Q.

Both these composts contain peat, but don't beat yourself up over it.  In spite of the crap pumped out by the Christophobic worshippers of Gaia, the earth goddess, the planet is actually laying down peat much faster than man could possibly consume it.
