Tom Bedford of UK Hardwoods is one of a handful of businesses speaking to Radio 5 Live's Wake Up to Money from Somerset.
He says the problem with Brexit is "customers not knowing whether to spend money or not".
It is also having an impact on his business where he had been looking at setting up new product lines. "It's slowing me down," he said.
"We'd be moving forward. We're all slightly sitting back and waiting to find out what happens before we put our cards on the table," he said.
That's slowing the economy down, he said.
