Passport running out

[Terpe]

Hi, my wife's passport runs out the end of october, just wondering if it's ok to renew this Philippine passport any time, after it runs out.We don't want to travel all the way to London in October, as we have no plans to go back to the philippines for the next year or 2. This is the only passport she has,and inside she has her ILR.

Her Phils passport may expire but the UK Visa is still valid.
