Thanks to everyone for your responses. I have now sorted out the problem and thought I'd post a solution for anyone else who may have this problem in the future.
Couldn't get any telephone numbers for Forex. So by searching Google I found a foreign exchange company called Moneycorp. They have branches in many different countries and process 2.5 million transactions a year. They have a Philippine Peso account and you arrange transfer of the funds into their account. They then exchange the money into sterling and transfer the money into your UK bank account. The cost is £15 for the transaction.
I spoke to someone called Ozdemir Gultkin on 0800 9101604 who was very helpful and explained the above process.
