You could try Bidvest Chepstow good money but hard work. Brakes have a new depot in potbury they are screaming for drivets Appetito are hiring over there too and Wincanton might be worth a call if you can commute over the bridge.
Theres a rumour going around that Farmfoods are taken on and putting through class 1 from warehouse might be worth a call to them
Coop through Xpo will put you through class 1 after 3 months and the money is good if you can commuteto Avonmoth
Braces I dont know if they are hiring but an ok job Allied Bakeries same job ok money Greggs Pontipridd ok money but very early starts
Lots of work unadvertised just use agency so you may be best to go in and ask
