Each station used the slogan of "Hotter and Fresher", signifying a shift towards a more contemporary slant in the station's music policy. The semi-network was disbanded after the GWR Group bought DMG Radio in 2002, in effect re-purchasing Mercury 96.6. The Mercury stations in Medway and West Kent were sold to the Kent Messenger Group. In 2003, Mercury 96.6 moved from St Albans to an industrial estate on the outskirts of Watford in an attempt to re-focus the station as a Watford-only station. This was due to the then Radio Authority regulations on local ownership of stations as the GWR Group already owned Chiltern FM, which has overlapping coverage in the St Albans and Hemel Hempstead areas. This move was in a bid to hold on to the station before the outgoing Radio Authority was replaced by Ofcom and in a bid to compete with then rival Capital Radio in London. Mercury FM by then took on the "Better Music Mix" format that originated from GWR in Bristol. In 2005, the St Albans and Watford Broadcasting Company was divested to a new company, Adventure Radio Holdings, an entertainment consortium which owns a theme park in Southend-on-Sea, Essex, and four other radio stations, including two in Essex. Despite its relatively independent status, the station was rebranded from Mercury 96.6 to Heart on Monday 26 July 2010 and switched to a softer adult contemporary music format. The changes coincided with a restructuring of Heart. In July 2016 the station owners Adventure Island signed a management contract with Communicorp which would see them offer extra support to both Heart Hertfordshire and Connect FM. In February 2019, Adventure Radio sold the station to Communicorp. Two months later, Communicorp acquired Shadow Radio Holdings, the owners of BOB fm in north Hertfordshire. On 31 May 2019, BOB fm ceased broadcasting and became a relay of Heart Hertfordshire. The merger coincided with the end of Heart's local breakfast and weekend programming.
