There are some some 5,000 people apparently around Windsor and Maidenhead who have no access to broadband, so there is a slight irony in running an online form for registration to improve broadband access. The registration campaign is featuring in the local press, so in theory visibility is not limited to those online, and those really wanting broadband will probably know which local library or cafe offers Internet access.
Berkshire is in a better position than many parts of the UK, as commercial projects alone should already get superfast broadband to around 80% of premises. The council led project is aiming to increase this to 90%, with the remainder getting a service of 2 Mbps or faster.
Many will assume registration will result in no changes to the plans, but unless people do register the council can only go on data passed to it by Ofcom/providers/BDUK which can often be at odds with the situation in a particular street or cul-de-sac. Remember also that the BDUK projects are not just a rural affair, if you have poor broadband and live in a town then you should also register.
