I used Porthcawl for ten years while I had a boat. Never a problem and never a big cost increase. Never made a claim though. Very approachable and easy to use.
Let them know you are thinking of leaving Trev and see what they offer.
If it is not a good offer, move.
I had the same a few years back, mine had always matched Porthcawl price when asked, then suddenly decided not to.
It was very easy to move to Porthcawl and I must say that I am happy that I did.
i am with ceta, mine went up my Β£20.
Insurance companies are boarderline crooks.
They have algorithms to try on price increases with customers that they suspect will pay without question. They have worked out that is how they can maximize their profits, even if a percentage of customers don't renew.
Sometimes you have to just leave.
No boat Rob just didn't have time to write " used to be with" π
One day i may get another boat though.
Just downsized my car so won't be trailering.
