Depending on who you are insured with, you can claim 1
windscreen replacement per annum without effecting your NCD; so
best you check with your insurance company on where you stand.
Alternatively I have used E-Glass to repair small chips &
cracks on my windscreen before and thoroughly recommend them. It's
a cheap & easy alternative depanding on how badly the glass is
damaged. Details below.
