Wow Step, I would let the people who you haven't got time to cancel with a respectable hour or so as notice come but I think I would be accepting the offer you have had just because of their position. That is worth a lot.
I had a thought on the insurance thing earlier. I am effecting a new contents only policy at the new house because our existing insurer will not include our bikes.
So, I phoned my new insurer and asked if they could cover the transit risk. Their policy wording didn't exclude it but as they weren't covering my old address (already have cover here with someone that won't insure the bikes) I didn't think it would be covered as the risk was starting at the new house.
So simple, I effected cover on my current home from two days prior to the move which means that the actual move is covered.
Now, I know that it is my claims experience risk and not some one off policy, but I also know that I will have the cover I need in the event something catastrophic happens.
To bump up the removal firm's insurance to £60k for my contents in the van costs ⅔ of my annual premium.
Perhaps the next removal firm will play things differently, I don't know, but I doubt it somehow.
