Hello, I am a solicitor with over 15 years experience. I will try to help you with this.
Do you think they have actually fixed the leak this time?
What is the value of the damage caused?
I am in a meeting all day now and will answer you this evening. Hope that is OK.
If you are right then you would have a valid claim against the conservatory company. You wouldn't be able to claim back the cost of the conservatory unless it is so defective you have to pull it down and replace it. At present you are not at that stage. If you have to incur costs getting it fixed you can claim these costs. As far as items damaged by water ingress this is claimable - if you have replaced the wooden floor with something more expensive so that it is less damaged by further water ingress you can try to claim the whole cost although you may only get the cost of like for like replacement. Te small claims limit is £10.000 so your claim will be in the small claims court which will keep lawyers out because there will be no awards for legal costs if someone does instruct a solicitor. This reduces the risks of bringing a claim. How do you justify your loss of earnings? If you are self employed you will need to show that you had lost work you missed out on on the dates you were at home.
If you are in work then how do you calculate your loss of earnings? Also you would need to justify that you needed to be there for all the time that you have claimed. Here is the link to the government website rre money claims. https://www.gov.uk/make-court-claim-for-money/overview
Yes you will be able to claim compensation for inconvenience but not necessarily for loss of earnings. When I say "if you are right" it is just my lawyerly caution.
