Property prices are reasonable and it has good communications to London for those of us who work in the City. Thankfully the C2C rail link has not been affected by the recent speed restrictions (Fenchurch Street station is 35 minutes from Basildon) and the A13 extension makes driving to Docklands a whole lot easier.
The leisure facilities in Basildon are excellent. The Festival leisure complex has a 12 screen cinema, bowling alley and over 10 clubs, bars and restaurants.
The town centre has a wide variety of shops although it has seemed to have suffered in recent years with the opening of Lakeside (15 minutes drive) and Bluewater (30 minutes drive).
Having lived all my life in Basildon I would say it is a nice place to raise a family. In my experience most neighbours tend to be friendly and willing to lend a hand should you ever need it.
