We treat each customer individually and their needs will vary dependent on the limits they need, the numbers of persons involved, claims history etc. so it would be hard for me to come on here and give a definative price.
What I will say is that I am not going to pretend, that we are mega-cheap just to entice a lot of business, because that is not the issue as far as I can see. The issue is getting the correct level of cover for to protect the policyholder.
Sole traders can get Public Liability starting from about £75 from the general market, BUT this is a policy that excludes property being worked upon, and will generally have height restrictions and restriction on the type of properties that you can work on. Therefore what is the actual value of this cover to the policyholder ? It will cover him for dropping a bucket on to someone or something but that is about all.
We know that the biggest risk in terms of cost to a window cleaner is scratching glass/frames and likewise we appreciate that they dont want all the small print of how high they are allowed to work and on what type of property.
Our product has all these covers built in automatically, but the cost will obviously be higher than the mega-cheap policy out there. However, as with all things, you get what you pay for.
Hope this helps.
