I think Rosie makes some important points.
The simple everyday things that we don't give much thought to can be very difficult during the early days.
Why not consider arriving to UK on Thursday, resting/acclimatising/time together on Friday. Even working on a list of essentials etc.
Spend the weekend together in the local town getting those essentials and even looking out for and listening for other Pinoy.
I remember telling my wife that I had never seen anyone from Phils in our local town, but first Saturday shopping she saw and heard lots!!
Made some contacts and able to chat on the phone in her own language.
A big help.
First days can be daunting and lonely.
Just my two centavos worth
