My pilot light on my Baxi Bermuda 552 will re light okay and ignite the main burner but usually goes out when the main burner goes off. Could it be the heat sensor next to the pilot is faulty or do I need to replace the pilot light fitting?

The fault may be a faulty sensor as this maintains the pilot gas valve, but first make sure that the pilot jets are clean and the flame is sufficient and playing on the thermocouple sensor. If the jets are dirty then the flame may be only partially heating the thermocouple.
