I can confirm that we had to get a resurvey after the 28 days were up. This was even though we had full intention of going ahead with the original order.
Out of interest, was your second quote the same as the first, or higher or lower?
It's up in the air at the minute. Our surveyor came out on the 6th of July to resurvey, sent off their costs on the 9th to the CP, the surveyor couldn't tell me what the costs were because he has to send them up the chain and isn't actually sure if what I receive as estimated construction charges from the CP are the same as what he sends off.
Long story short, I emailed Amvia on the 20th of July to see if they had received the costs sent over to them on the 9th by the surveyor (I'm assuming Amvia are indeed the CP(?)). They replied to say they didn't have anything from openreach and it was still with the Openreach's planning team (very strange I thought).
I Left it at that and was going to chase the following week. Then, out of the blue, the surveyor text me on the 24th of July to say the cost had been accepted with zero additional costs (we had already paid Amvia the amount on the first quote).
I still to this day have not heard from Amvia to let me know that the order went through and is going ahead and whether we are due a partial refund (due to needing less duct for the project) or the costs are remaining the same.
The 450m of duct, bends and junction box covers arrived via lorry today and KN networks (working on behalf of Openreach) were out to look at the JF4 they have to build beside our field on the roadside, they are due to complete it within the next week. So things are progressing quite rapidly without Amvia it seems lol
