Huge cracks in walls

I'm looking for some advice on how to proceed with the situation I find myself in. There are cracks appearing all the wall and ceiling in my house. A few months ago I reported the cracks to my insurance company as possible subsidence. Based on the photos have sent to my insurance company they have ruled out subsidence. They have said the cracks are just cosmetic and to hire someone to repair the cracks myself. I really wish I could believe them, but the existing cracks keep getting bigger and new crack keep appearing. Today I put a tape measure in the biggest crack to see deep in went and it was 24 cm deep.
I can understand why the insurance say its not subsidence. There are no external cracks and most of the cracks are upstairs along the wall that joins to next doors. While it probably isn’t subsidence, I still think it is structural. Worst crack is now so wide that I can see that the bricks behind the plaster are also cracked.

I suspect the cracks are something to do with the renovation work my neighbours did a couple of years ago. My old neighbour died. He had not done any modernising to his home for a long time, so it probably needed a lot of work to bring it up to a modern standard. The new owners did a back to brick renovation along with putting a whole new roof on. The roofing work caused me a lot of issues at the time and I did raise my concerns with the roofer. The roofer did not like being questioned and became quite threatening towards me. Unfortunately, the roofer was a relation of the women who owns the house and that relationship turned sour too. I remember thinking at the time it was the strangest renovation I have ever seen. Other than the roofer no proper trades people worked on the house. The owner’s ‘contractor’ moved into house for about a year and did the rest of the work himself. I received no notice any work was going to done and no party wall agreement was issued. I am not a 100% sure if I should have received one or not. I don’t know if they should have issued one for the roof replacement. I suspect they may have removed an internal wall upstairs. The house used to be 3 bedrooms, but when it was rented out it was listed as 2 bedrooms. The cracks on walls are inline with what you would expect from a house suffering from roof spread. My house is a Victorian terrace and from what I understand they were only built to hold the weight of a traditional slate roof. I know my neighbours changed their roof from slate to something else, but I don’t know enough about roofing to identify what tiles they are. If the new tiles are heavier, they could have caused roof spread. I know they did not get any form of approval from the council for any of the work they had done. Also, I’ve noticed I seem to be able to hear a lot of what the tenants living next door are doing. I never heard the guy make a sound when he lived there.

So now I found myself in a situation where I have some very big very concerning cracks on my walls and ceiling, but my home insurance company are not interested at all. I suspect that it has something to do with work my neighbours have had done, but I’m not an expect so I could be wrong. I haven’t done any renovation or building work myself that could have caused structural issues. The situation is very stressful. The cracks on the ceiling in the smaller bedroom are now so bad that I am really concerned about how safe it is for my family to sleep in there. I feel out of my depth with this. My house feels unsafe, but it might be overreacting. The relationship with my neighbour is broken to the point we can’t have a friendly chat about this. If the issue is coming from her side than I would probably have to go down the legal route to recover costs. While I can’t ignore the damage I am scared of taking legal action against my neighbour. I fear there would be a backlash against me and things could get nasty. I need to establish for certain what’s causing the cracks. I thought my insurance company would at least send an accessor out to look at my house and tell me what the cause is, but they have refused to do that. A local surveyor has quoted me £1300 to assess my house and write a report for me. I can’t afford to spend that much, but I desperately need answers. Maybe I’m being suborn but I don’t think I should have to pay for a surveyor.

Has anyone else been in a similar situation? How did you get it resolved?

We are not a fan of Admiral. A neighbour of ours had a leak whilst on holiday and came back to a waterfall down his stairs. The claim was logged but not sent on for processing. Four months later he chased up and found out it had not been processed. All the walls in his house had collapsed and he was out of the house for a total of 18 months!

Hi! My saga continues... insurers originally said they were going to underpin the back of the house due to clay shrinkage in general. But now they're saying as our neighbour has also put a claim in they're going to put a root barrier round both houses (semi detached so one building in effect). Neighbour has had some lower branches of his oak removed, but he's blaming the neighbour on his side who has a weeping willow. I just want something to happen, our insurers said neighbours insurer is delaying things. Both insurers using the same structural engineers? Neighbours cracks are worse than ours

Thank you for updating. It begs the question, what is the point of insurance if they constantly drag their feet instead of just sorting the issue

They will get out of paying if they can.
