Most homes need gutters cleaned once a year, and twice if trees overhang. Autumn after leaf fall is the key time, with a check in winter storms, a spring look for moss and seeds, and care in summer to avoid disturbing active nests. Little and often beats one big job.
Autumn and winter
Late October to November is when most leaves have dropped, so it is the best time for a full clean. In winter, look at gutters after storms and heavy rain. Freezing weather can crack joints that are holding water.
Spring
March to May is when seeds, blossom and moss show up. Homes under trees often need a second, lighter visit. It is also a good time to check for rust or flaking after the winter.
Summer
Birds nest from spring through summer, and active nests are protected by law, so leave them alone until the young have gone. Check the gutters again once nesting is over.

Late autumn, once most leaves have fallen, and again in late spring if trees overhang.
