So been doing this for a while and if you are getting digital download games well worth the effort
Create a US Amazon account using a US address etc
Create a US psn account
Buy psn credit from the US Amazon store so you pay 0 tax on it (if you buy the games direct from them you have to pay tax, if you buy credit you pay no tax)
Redeem the codes against your US psn account
Buy whatever game from your US psn account ps store for much cheaper than in the UK - around £35 for most new games
Download game to your US psn profile and install
Switch to your UK psn profile and play the game
Profit
