Hertfordshire is a county of contrasts, where the leafy lanes of Radlett and the suburban sprawl of Harlow are separated by more than just miles. With a population of around 1,378,888 spread across 51 postcode districts, this Home Counties gem offers everything from chocolate-box villages with names like Church End and Tea Green to sprawling commuter towns. It is a place where the property market tells a story of winners and losers, and where the schools are generally good but not uniformly outstanding. Let the numbers do the talking.
At a Glance
Hertfordshire is home to about 1,378,888 people living in 51 postcode districts. Its largest towns, if you can call them that, include the charmingly named Church End, Green End, Rush Green, Wandon End, Peters Green, and Tea Green. The average sale price across the county sits at £521,340, which is 49% higher than the England and Wales average. On the deprivation scale, Hertfordshire scores a comfortable 7.1 out of 10 (where 1 is most deprived and 10 least), with individual districts ranging from 4 to 9. Of its 508 Ofsted-rated schools, 15.7% hold the top grade of Outstanding. A word of caution: a postcode area can spill across county lines, so some districts named here sit just outside the county itself.
Hertfordshire at a glance

The Property Divide
| Postcode district | Average price | |
|---|---|---|
| Most expensive district | WD7 (Radlett) | £1,052,694 |
| Least expensive district | CM20 (Harlow) | £298,222 |
Nowhere is Hertfordshire’s inequality more starkly visible than in its property market. The most expensive district is WD7 (Radlett), where the average home costs a whopping £1,052,694. At the other end of the scale, CM20 (Harlow) offers a relative bargain at £298,222. That is a gap of about 3.5 times, meaning a house in Radlett is worth more than three and a half Harlow homes. The overall county average of £521,340, 49% above the England and Wales average, shows that Hertfordshire as a whole is firmly in the pricier half of the country, but the extremes are sharp. Radlett’s leafy affluence and proximity to London drive its prices sky-high, while Harlow, with its postwar new-town layout and lower transport links, keeps values grounded. The gap between the dearest and cheapest districts is not just a matter of square footage; it reflects deep differences in local income, transport links, and historical cachet.
Rich and Poor
Deprivation figures paint a similar picture of extremes, albeit less extreme than the property gap. The average Index of Multiple Deprivation decile across Hertfordshire districts is 7.1, meaning the county is generally affluent. But the range runs from 4 to 9. No district hits the top decile of 10, but none fall below 4 either. Radlett (WD7) sits comfortably in the least deprived end, likely close to decile 9, while Harlow (CM20) is nearer to decile 4, the most deprived in the county. In practical terms, this means that even Harlow’s most deprived areas are still better off than many places in the North or Midlands, but within Hertfordshire the gap is noticeable. The county’s overall high score reflects its strong local economy, good schools, and desirable housing stock, but the variation reminds us that not every postcode shares in the prosperity equally.
Schools
Hertfordshire’s school system is solid, if not stellar. Of the 508 schools inspected by Ofsted, 15.7% have achieved the top grade of Outstanding. That is roughly one in six, a respectable showing but far from a clean sweep. The county’s good deprivation scores suggest that funding and parental support are generally strong, yet the proportion of Outstanding schools leaves room for improvement. The geographic distribution of top-rated schools likely mirrors the property divide: Radlett’s schools benefit from affluent parent bodies, while Harlow’s may struggle with higher deprivation. For families moving to Hertfordshire, the postcode will heavily influence school choice, and the 15.7% figure underscores that not every local school can be a standout.
The Bottom Line
Hertfordshire is a county of two halves, at least in property and deprivation terms. From Radlett’s million-pound homes to Harlow’s relative affordability, the postcode you pick shapes your life in more ways than one. The average sale price of £521,340 is a reminder that Hertfordshire is no cheap date, but neither is it out of reach for the determined buyer. The schools are decent, the deprivation low, and the villages have names that sound like they came from a children’s story. But if you are looking for a place where the numbers tell a simple tale, think again. Radlett and Harlow may share a county, but they inhabit different worlds entirely.
