    It looks like it may be powdery mildew
    Some info here

    Warm humid days followed by cool nights can contribute to the cause

    I'd agree with the above - IME, it does seem prevalent this year on both cucumber and Courgette.

    Thank you for info going to garden center this week. Even though they have got it on the cucumbers seem to be doing alright.

    Often if the weather improves they shrug it off.
    If it's just a few lower leaves on an otherwise healthy fast growing plant, I think I'd just cut the affected leaves off and get them out of the way. 
    It's also important to keep the compost moist when it's warm - pots can dry out quickly this time of year. Stress and weather are the root cause of the problem

    Thanks will do that. Think I am going have to cut a hole in the glass to let them out look really good.

    I get that most years as mine are in the greenhouse and the moist air encourages powdery mildew growth.
    I always treat it with bicarbonate of soda .

    Google bicarbonate of soda treatment for cucumbers. Its a very cheap fix (about a quid). I spray regularly throughout the season to keep it in check.

    Make sure you get the mix right otherwise you end up with a lot of very scorched leaves :)

    A feed of seaweed extract every couple of weeks is a great tonic for most plants
