Swindon-based ESP, which was already ISO 9000 and ISO 14001 accredited, said achieving the accreditations was a relatively simple process.

Managing director Paul Bradley said: "It only took us about three weeks, but we were very well set up already with the ISO 9000 and 14001 accreditations. We're a responsible business anyway and most of our customers are fairly responsible."

ESP, which was awarded both FSC and PEFC simultaneously on 15 May, has a good environmental track record, although Bradley said that being green was not the be-all and end-all.

"We're as green as we can possible be without affecting the price," he said.

"The reality is people want you to be environmentally friendly, but they don't want to pay any more for it."

The company, which employs 72 staff and has a turnover of more than £11m, has recently invested in new equipment, adding an SM102 five-colour perfector to its print firepower.
