If you passed your test before 1991, you shouldnt need a trailer test.
it comes along with the 7.5t allowance on your licence.
I bought a 6x4 trailer for starting up last year, its adequate for the work I get.
good luck and best regards for 2013
ifor are very good and hold there price well 4 wheel easy to reverse
I've got the 6x4 IWT with mesh sides and it's perfect. Holds about a week's waste, so it's cost-effective at the tip. Just keep it secure.
With hindsight the 4-wheeled would be worth the extra, a puncture on my 2-wheel is a pain. They do hold their value, so a used one is often not a good buy, but they come up occasionally.
I have a 8x4 braked Ifor Williams with full mesh sides. You would be amazed how much you can fit in in, cover the top in tarp and strap it down. Had mine for about 10 years +, brilliant trailer I bought new. Looking for another similar this year. Will definately be looking at a IWT.
Would agree with Ryan, we have one of these (twin axle - a GD 85 I think) and they are capacious with the mesh sides and stable when being towed. Can also get a ride-on in them up the ramp.
Ironically, we hardly use ours now (not through any fault of the trailer ;-) as our working practices changed. Occasionally used to go get a couple cube of mulch...
My Indespension, 8x5, twin axle, with ramp has served me 17 years(with one new floor) of constant use for plant, arisings and aggregates. If you don't want to put equipment on it, consider a tipping facility.
