Leaking valley of next door neighbours thatched roof area.

[Guest]

Where the valley area of my neighbour hasn’t been maintained part of her thatch has fallen in the valley and the rain is coming down my inside lounge walls.
should she be responsible for the cost of repair and my internal damage. Insurance company say I can’t claim off of her insurance as it’s not storm damage it’s lack of maintenance

From the brief details you give it would appear that your neighbour is liable for the cost of repairs to your property.

You cannot claim against her insurance.
You need to write to her (first class post with free certificate of posting) telling her you hold her responsible and anticipate she will meet the cost.
Also advise her she should notify her insurance and make a claim under the public liability of her policy.

OR you could try making a claim under your policy.
Your insurers however might refuse to pay out until your neighbour carries out remedial works to her property
