Public Liability Insurance is something that most tradesmen nowadays are looking at even if it isn't a type of insurance that they are legally required for them to be able to undertake their work. Basically Public Liability Insurance will cover for any third party injury or property damage that you may accidentally cause during the course of their building work.
Although it is not a legally compulsory insurance type a lot of people will insist that you have it before you are allowed to undertake any work on their property as things such as liability claims do seem to be coming more common place these days so people want to make sure that anyone working on their property has adequate cover should the worst happen and a claim have to be made.
Many people assume that if they get type of insurance then it will generally cover them for building works but it is specific only to the trade of builders and would not cover if you were held liable for any third party property damage or injury that you caused from doing any roofing or kitchen and bathroom fitting for example.
Most people also assume that if they damage the property that they are working on then this will be covered under this type of insurance but it is only things such as if you were to enter the property that you were working on and accidentally knocked over a vase and were held liable to repair or replace it or if you left your tools out and someone was to trip over them and injure themselves.
The general prices for a years cover for a builder getting Public Liability Insurance is usually quite cheap at around £65 for one million pounds worth of cover but if for any reason you think that this will not suffice most insurers will be able to give you other quotations at both two million and five million pounds worth of cover but obviously these would be more expensive than the basic one million cover.
