Blyth-registered CoreISP trades as Core Broadband and, our records say, sells fixed wireless and full fibre to homes and businesses.
About CoreISP
CoreISP's broadband goes by the name Core Broadband, and our records list fixed wireless, where the signal reaches you by radio from a nearby mast, alongside full fibre for homes and businesses. The company, CoreISP Group Limited, was formed in March 2023 and has its registered office on Stanley Street in Blyth, Northumberland.
Where it sells is less clear. Our records point to Dorset, while the company is registered in the North East, and its website gave a security error when we checked this month. Get confirmation from CoreISP that it covers your address before signing up.
