This qualifying tie in Coventry will be played on a hard court, with the following week's tournament in Stuttgart the first of Emma Raducanu's clay court season.
With a clay court training block scheduled after next week's Miami Open, it is far from ideal for anyone then to switch back to a hard court for a week before beginning the clay season in earnest.
Raducanu's representatives also point to her ongoing wrist issue, which is limiting practice and could be put under further strain by regularly switching surfaces.
But this will be the third time in a row Raducanu has been missing from the British team. She was also absent because of the wrist injury from last November's Billie Jean King Cup Finals, and then chose a tour event in Auckland over the United Cup at the beginning of this year.
And there is no escaping the fact that Raducanu's presence in Stuttgart is expected by sponsors Porsche, as the 20-year-old is a brand ambassador for the car maker.
