Back then, you would also have had to pay a substantial premium on the first three years of service: I think it worked out as about £3.6K+VAT (i.e. you were paying £100 over Cerberus' standard FTTP pricing for 3 years)Jesus that was expensive, given the fairly short distance to the agg node. Mine cost £3.7k back in 2017 when it was still under the construction band pricing scheme. Mine was band D and IIRC distance to agg node is 800m.
I was one of those who benefitted from the newer pricing in 2018, as my previous quote for band G was higher. However, installation prices have risen substantially since then, perhaps reflecting that Openreach have committed heavily to Fibre First and don't want to divert resources away.
For those who don't know: I made a spreadsheet recording FTTPoD initial estimates and post-survey prices reported by thinkbroadband users.
There are only 11 reports from 2020 and 7 reports from 2021, but across all of those the lowest confirmed pricing was £8,157+VAT.
These days you can be pretty sure that any FTTPoD installation will likely cost £8K-£12K (+VAT). If you would be prepared to pay that, then committing to the £250 is not a big deal. (Technically you're not actually paying for a survey; you're placing an order for FTTPoD. You can exit the contract once the confirmed pricing is given, but you pay £250 to do so. If you want to continue, you have 30 days to pay the entire installation fee up-front).
The OP's 6 months from survey to provisioning is pretty good, but there are no guarantees and it can take a lot longer: mine was 3.5 months to get the survey, and another 14 months for installation. Meanwhile, Openreach is deploying native FTTP across large swathes of the country, with an ambition for 80% coverage by end of 2026. Therefore, anybody considering FTTPoD now has to weigh up the risk that by the time it's installed, they may only get a year or two's benefit from it.
