Bexley and Thurrock both feature another time on the top ten list, with DA8 in Bexley having a price tag of £347,495 and RM17 in Thurrock at £312,768.

Plus, Kent's Gravesham and Dartford were also ranked as some of the cheapest hotspots, with the two sets at around £330,000 each. 

Colby Short, Co-Founder and CEO of GetAgent says: "Living in a particular postcode can add thousands to your home’s value, whether that’s due to having prestigious schools (with catchment areas notoriously hard to get into) or even good transport links for commuters.

"Surprisingly, while you might assume that homes closer to the capital would fetch higher asking prices, our research actually shows that it’s countryside destinations that are topping the list of expensive postcodes.

"As we’ve seen a more hybrid way of working come into play over the past couple of years, it’s clear to see that there’s demand for homes in the countryside, and even remote areas of the UK, as people leave the city life for space further afield."
