DIY HIP packs are a possibility for home owners. I am apprehensive to say the least about peole compiling their own HIP packs.
One of my main reasons behind this apprehension is legal liabilities if the home owner was to incorrectly compile the HIP.I must state that i do own a independent
HIP provider business so there is a level of bias based on this post.
However, we carry a very high level of insurance up to £2 million for some aspects and high levels in others. As a home seller you probably would be able to get insurance for your DIY HIP, where from i do not know. If you were to get insurance for your DIY HIP i would suggest it would be a cheaper option commisioning it from an independent supplier.
In todays 'claim society' it is something to consider.
