Sustained Skills For Specialist Services

The provision of Jointer Training is a contentious topic in the UK Power Industry – standards are collapsing, craftmanship is devalued, pockets are hurting and an illusion clouds the market that some Trainers can wave a magic wand and create the perfect Jointer in 4 days.

OK, it’s not quite the Wild West but as a UK leading distributor of Jointing Equipment at Thorne & Derrick we hold a duty of responsibility to support the safe and reliable installation of these products by promoting excellent standards of workmanship.

Accredited training courses can protect power and people against the danger of fatal Volts.
