This is an easy to get to LPG point with access to the M4 and A48 with Dual carriageway from both Junction 38 M4 and A48 Junction 41 - link to M4. Plenty of room to maneuver with access to the pump on both sides.
there is also a Lidl and Halfords here.
ignore the service station and go down tot he shopping complex and use the ASDAs LPG. - be aware the pump is on the right hand side when you pull in and if they close the payment booth in front you will have a tight turning area to get the the payment booth on the left.
