There are a number of quite complex reasons why Open Reach build where they are building. In no particular order

The first is *perceived* returns based on uptake percentages. OR use a very odd formula for working this out that is based on quite old data.

Secondly OR avoids like the plague is areas where there are direct buried cables in the ground.

Thirdly areas where a large number of the poles need to be replaced to carry overhead fibre as well as copper.

Fourthly squashing competition - OR will swear on a stack of bibles that this is not the case - but it occurs an amazing number of times that an Alternative Network provider starts building and OR turn up and overbuild their network. Bear in mind that OR know who is about to build where from WhereAbouts date - has to be submitted to them to access the OR network of poles, ducts and chambers.

So if you were cynical you might suggest that Community Fibre, VM and G Networks were not squash able so OR doesn't bother. Actually G Networks do have issues of their own and have rather changed tack recently having spent a fortune digging holes in street in central London and then, perplexingly, leaving the physical infrastructure devoid of fibre. Real head scratcher that.  https://www.ispreview.co.uk/index.php/2024/11/london-full-fibre-broadband-isp-g-network-cuts-jobs-and-shifts-strategy.html

Community Fibre seem to have got the bit between their teeth again after a lull and are going gangbusters filling in gaps in the network.

I'd avoid VM as their network is a total mess and the *upstream* speeds [vital if you are backing up you phone to the cloud or even sending large emails] are not much better than FTTC [the old OR fake hybrid fibre nonsense].

I’d also add that G Network were spending something like £100m rolling out fttp across Battersea / lavender hill area . As I say openreach probably see no reason to overbuild and use limited capital to do so . They will be desert pockets of not passed homes as fttp is rolled out, I’d guess at some point providers will circle back and infill those areas. But community fibre and G network seem to be the ones building out fttp in Wandsworth / Battersea and BTC specifically

There’s community fibre fttp 1gbps been rollout across most of btc - broomwood road across to Battersea rise it’s been in the ground a year now . Do remember there is already competition in the ground with Virgin media cable . Maybe community fibre have secured the permitting rights and BT openreach see no reason to use limited capital in areas with heavy competition already.

As a suggestion, why not contact them and ask them?

Anyone know why the whole area Between the Commons north of Thurleigh Road is an FTTP desert? Openreach provides full fibre to the premises in Wansdworth and Balham but not Battersea. Can anyone shed light?
