Knew that would get your attention.
Cleaning above a glass canopy today with my 45ft tucker pole when one of the clips caught the edge, not hard just caught it.
Being toughened glass it shattered.

According to a double glazing friend of mine, in excess of £2500 worth. Luckily my Public liability will cover it, (i've checked) but there will be a £250 excess.
Got to fill the forms in and see how we go.
I was lucky though because I was so shell-shocked by this that on leaving site I didn't clamp on double 7metre ladders, drove home 4 miles away and they didn't fall off.

Now
that could have been expensive
So what's your most expensive accident.
