<P> Although the programme is set in Billericay , Essex , and Barry , Vale of Glamorgan , the three series were shot largely in Cardiff ( which acted as the city itself but also as parts of Billericay ) , and also in Barry itself and the surrounding area , including Dinas Powys , Sully and Penarth . The show 's popularity has been credited with boosting the tourist trade to Barry and its popular seafront of Barry Island , through visitors wishing to visit the various filming locations . Gavin 's house was set in Billericay but was actually filmed on location in Laburnam Way , Dinas Powys in Wales . The opening episode features location shooting in Leicester Square in London which was filmed in 2006 . </P>
