Compare the plug shapes, voltage and frequency in United Kingdom and Philippines, and find out which adapter you need before you travel.
Adapter required
Yes — coming from United Kingdom, you will need a travel adapter for Philippines. United Kingdom uses Type G plugs, and Philippines uses Type A/Type B/Type C, so the pin shapes will not fit any wall socket. The mains frequency is also different (50 Hz vs 60 Hz). This rarely matters for electronics but can affect motor-driven devices like clocks and shavers.
