Various reports are in live feeds, on the ITV site and elsewhere that the government is denying it has placed an order for Dyson ventilators. It says it has "expressed an interest" in ordering 10,000 once the ventilator has passed regulatory approval but will not order them until then, which as yet it it has not. It looks like 'ready in early April" should be interpreted as "ready in April for the first iteration of regulatory testing. It might pass first time, or several more iterations may be required."

Meanwhile a substantial order appears to have been placed elsewhere for designs that are already approved.
