Hi Norman, welcome here to the forum.
Technically, if you are legally free to marry and she is legally free to marry no problem.
Of course it's understood that you would meet her face-to-face and get to know each other before actually getting married.
Of more importance to your question is what your plans would be after marriage.
Live in the Philippines together ? or
Return to UK to live and settle as a couple ?
If you had a plan to apply for a spouse visa and return to UK to settle, then I have to say based on the income and saving you have, then you would not be eligible for a visa.
You need to prove an annual gross income of £18600
Well, food for thought anyway.
Better to be aware now than after marriage.
