With or without dual citizenship, your pension(s) are safe on emigration to the Philippines. There is a reciprocal tax arrangement between UK and the Philippines. In fact, pension wise, you are better off coming to the Philippines than emigrating to any of the Commonwealth countries. Those from UK who emigrate to Commonwealth countries on retirement have their age related (OAP) pension frozen at the rate it was on emigration. Therefore its' buying power decreases annually. Coming to the Philippines however, means that you will automatically get the annual increases in the age related pension. The "frozen" rule does not apply to any other private or occupational pensions that you may have. Note that as you will not be resident in the UK, you will not be entitled to the Winter Fuel Allowance. Your OAP pension can be paid into a UK bank or into a local bank. It will be converted in UK at the BofE official exchange rate on the day of transfer and paid into any local bank in pesos. If your accumulated pensions exceed 10,800 pounds per annum, you will still be taxed in UK at 20% of any amount exceeding the base figure. So as far as UK generated pensions are concerned you are safe, but I don't know if there are any other merits in obtaining dual citizenship. Advice on that issue should come from those who are far more knowledgeable on the subject than I am.
