In 1931, due to the rapid growth of Upton, Cheshire County Council agreed to transfer Upton to one of the neighbouring urban authorities (Birkrnhead and Wallasey).

The residents were given a completely free vote as to whether Upton should join Birkenhead or Wallasey, Both authorities fought a lively campaign.

Polling day was set as 10th March 1931. On 9th March, a fire engine from Wallasey Fire Brigade arrived in the village, bearing a placard saying 'We Can reach any fire in Upton in Ten Minutes'. Shortly afterwards a Birkenhead fire engine arrived with a placard saying 'Why wait ten minutes?'

The result of the poll was 661 in favour of joining Birkenhead and 240 for Wallasey, so Upton became part of Birkenhead.
