Harlow property market September 2025 warmer or colder?
Jukes Estate Agents take their regular monthly look at the Harlow property market. Using data from property experts The Advisory (https://www.theadvisory.co.uk/), they look at the the four postcode sectors CM17, CM18, CM19 & CM20. The method is simply. They divide the amount of properties on the market by the amount of properties sold. This gives a percentage that they choose to call degrees. Therefore, we can see if the market is cooling down or heating up.
CM17
This postcode has dropped by 3% (3 degreeS) in the last month. Data sourced from The Advisory (https://www.theadvisory.co.uk/).
When we analyse this postcode we can see the following results since January 2024:
2024:
January 43%, February 39%, March 40%, April 45%, May 45%, June 47%.
July 49%, August 49%, September 45%, October 46%, November 47%, December 49%.
2025:
January 2025 54%, February 2025 50%, March 2025 52%, April 2025 57%, May 2025 56%. June 2025 56%. July 56%. August 55%. September 52%
CM17 dropped by 3% last month. Considering the time of year, we were expecting that. At 52% (degrees) it is still higher than at any time in 2024 and hopefully we will see an increase next month as things return to normal after the summer holidays.
CM18
CM18 dropped A WHOPPING 8% (degrees) 1% last month.
Let’s look at what this postcode has done since Jan 2024:
2024
January 57%, February 55%, March 62%, April 63%, May 61%, June 58%.
July 62%, August 61%, September 59%, October 55%, November 58%, December 63%.
2025
January 68%, February 63%, March 68%, April 70%, May 64%. June 66%. July 66%. August 65%. September 57%
CM18 dropped 8% last month which , even for allowing for the Summer holidays was not good!
You have to go back to October 2024 to see it that low. When you consider that back in April 2025 it stood at 70% (degrees), you can see that things need to start improving quickly!
CM19
Harlow property market September 2025 warmer or colder?
CM19 dropped by 3% (degrees) last month.
Let’s look at its performance since Jan 2024:
2024
January 45%, February 45%, March 52%, April 51%, May 47%, June 51%.
July 54%, August 56%, September 55%, October 56%, November 56%, December 58%.
2025
January 58%, February 52%, March 53%, April 53%, May 48%. June 51%. July 53%. August 52%. September 49%.
It has been a difficult year for CM19 so far but this is, in the main, almost certainly down to CM19 5 Roydon properties that are taken an age to sell! Only two months (May 2025 & May 2024) have been lower then the current 49%. #
CM20
CM20 has at last seen a large fall of 5% (5 degrees) in the last month.
Let’s look at its performance since Jan 2024:
2024
January 51%, February 49%, March 55%, April 56%, May 56%, June 60%.
July 61%, August 50%, September 55%, October 59%, November 61%, December 62%.
2025
January 66%, February 61%, March 61%, April 63%, May 56%. June 53%. July 52%. August 55%. September 50%.
CM20 had just started to recover and now it is down another 5% (degrees). It is the lowest since August 2024. Worrying!!
Conclusion
All four Harlow postcodes saw drops this month. Whilst that was sort of expected (summer holidays), it was the level of drops, especially in CM18 & CM20 that has started small alarm bells ringing.
Now, this doesn’t mean the market is in trouble because I suspect this is down to the holiday season and that old chestnut, over pricing. Yes it is still going on! It’s crazy and you end up getting even less for your property than you would have by pricing it correctly in the first place!
