Hedgehog gutter guards are useless to be honest.. They actually help to clog up the gutters thus rendering the gutters useless, unable to do their job - leaves and debris just sit on top of it all and the whole gutter becomes clogged. We're actually doing a few jobs now taking it all out, clearing the gutters (debris still gets in there) and fitting down pipe balloons/protectors and then doing a once yearly clean.
