Why UK rains a lot?
This is because the mountains of the northern and western UK force the prevailing westerly winds to rise, which cools the air and consequently enhances the formation of cloud and rain in these locations (this is known as orographic enhancement).

Can it rain for 40 days?
Nature is a dynamical system and for rain to occur, it requires a low pressure area to staganate over a region. Fortunately, low pressure is more dynamical than the high pressure and therefore the probability of a low pressure to persist for 40 days at a stretch is almost zero.
