I suggest that the external wall mounted water meters currently being installed at the numerous new build estates in the area are evaluated and possibly redesigned.
This year (2018) we had 1 short sharp cold snap where the temperature dropped to -3 or -4 degrees but combined with a fierce wind chill factor, the pipes inside the water meter casings in semi-exposed positions froze at the junction in the water meter casing. This is obviously a design flaw and the casing should be either re-designed to have better internal insulation, or possibly in existing installations a secondary casing added. 
With thousands of new build houses on the cards this flaw in the casing design has been identified and 
 now should be addressed before the next batch is manufactured.
