Compost is the term used across the pond for potting media. You are correct though that compost, meaning decomposed plant matter, will kill them.

While I can't help you with sourcing the soil for them, you can make an international request from the seedbank. You qualify for most sundews, flytraps, and pitcher plants and can request 3 packs per quarter. Add a bonus and add-on and you can get 5 packs of various seeds.
We have some growers in the UK on this board. Hopefully they will chime in on where to get media. Do not order anything on Amazon unless someone confirms that it is safe. There are a variety out there that will poison your plants. There are also some that work one time and poison them the next. These are mostly prepared and shipped from China.
