    You can get mould and mildew wash in 5l tubs from diy sheds. Soak that in for a while first and then wash off.
    Is I pebbled dash or smooth render? Pebble dash will be near impossible to clean effectively probably

    I would pressure wash very gently and then spray with algae and mould cleaner like patio magic (b and q)and leave it on the walls.
