A PropCast weather report showing the areas where homes are most in demand has been produced by property experts at TheAdvisory.
It was created by calculating the number of ‘Sold STC’ and ‘Under Offer’ properties as a percentage of the total homes for sale.
Each postcode is given a heat rating, with anything above 50 degrees meaning it is ‘very hot’ and an ‘extreme sellers market’.
The map also shows whether the heat rating for each area has gone up or down since last month.
Below are the 14 postcode areas in the north east of England with the highest heat rating according to the latest weather map for May 2025, including two where demand has risen rapidly.
