Yes, sorry I never made it clear in my question, but you answered anyway! I have bled the excess from a Rad, and it keeps increasing slowly over a day or 2.

Thanks Very Much for answering.

reduce pressure by bleeding excess from a radiator, if the pressure increases again, your filling loop may be passing, remove it and try again, if successful, replace filling loop, if it still happens, you will need to get the dhw heat exchanger replaced as there is a leak between the primary and secondary waterways
