Insurance claim - rejected for non disclosure for a rejected claim 5 years ago

I am writing to ask is it possible to obtain advice



we have insurance cover and have made a claim, the claim has been rejected (but was originally accepted and repairs started) as the Insurer has come back and said we never disclosed a claim made 5 years ago and therefore the claim is rejected, we have loss assessors appointed and they appointed contractors, the insurance will pay them for the work they authorised but have rejected the claim



Is there legal redress for us, we are based in north England.



Thanks
