Box will follow Neston and Lacock in being connected to superfast broadband.
Wiltshire Council has been working with BT as part of a multi-million pound contact to improve services in rural areas, which aims to see 91 per cent of premises in the county connected to speeds of 24Mpbs by the end of March 2016.
In December, Royal Wootton Bassett became the first town in the county to benefit from the scheme and BT has promised that rural areas will soon receive upgrades.
BT programme manager Matt Lloyd told last Thursday’s Corsham Area Board meeting: “The transformation of broadband is part of a larger programme called Wiltshire Online.
“The government has recognised there is a gap in the coverage of broadband nationwide, and that the commercial delivery of broadband is only going so far in terms of investment in the country, so rural counties are going to miss out unless something is done.
“We have spent a long time preparing but we are now entering our first installation phase.
"There are 17,000m of cables now in place, and we have deployed two cabinets in Corsham.”
"We’re looking to bring services live in the Neston and Lacock area in the summer, and then we will be progressing towards the Box exchange area later in the year.”
Andy Moores, a business systems manager at Leafield Industrial on the Leafield Industrial Estate, said: “At the moment, we have put three different lines in just to get a reasonable speed at quite an expense, so high-speed broadband would be a godsend.
“We are also having to store a lot of our data in-house, as we can’t really access any of the online cloud solutions and our connection is very, very slow.
“We can use the new technology to a greater degree and it’s better for security, as we can put in new external back-ups. It will make a huge difference to us.”
Other areas to benefit from latest phase include Avoncliff and Westwood, near Bradford on Avon, and several villages near Salisbury.
