The typical property in CB1

CB1 sits in Cambridge City Council. The outcode covers central south Cambridge including the railway station area, Mill Road, Romsey, parts of Petersfield and the Downing site. Mill Road is a noted independent retail street with high ethnic diversity. Housing is dominated by Victorian and Edwardian terraces (the so-called Cambridge "Kite" area) and newer apartment development around the station. The CB1 area around the station has been substantially redeveloped since 2010 with significant new commercial and residential building (the CB1 development).

Cambridge station sits in CB1 and provides services on the West Anglia Main Line to London King's Cross (Cambridge North) and London Liverpool Street in around 75 minutes, and on the Cambridge Line via Bishop's Stortford. The station was redeveloped from 2011 onwards.

Employment is dominated by Cambridge University, Anglia Ruskin University, the technology sector (Cambridge has the largest tech cluster outside London, "Silicon Fen"), and the biomedical campus at adjacent Addenbrooke's Hospital.

Cambridge City Council operates additional HMO licensing in defined areas. The Renters' Rights Act 2026 has abolished Section 21 evictions. The proposed 2030 EPC C standard, if enacted, will be a substantial cost on Victorian terrace stock.
