Keeping temporary postal address

Hi,

I will be relocating to UK for job in coming weeks.
I was wondering what should do about my address in Belgium ?.
Would like to keep a address in Belgium to take care of my bank account(Belgium bank), commune and other administrative things.

Is there any service that I can use to keep an address in Belgium ?.
Which I can use for my bank and other things.

What other options are available ?..

Thanks
