Crowborough homes sold for a £437,500 median over the past year, £48,500 above the Wealden average. Prices by type, and how the district's towns compare.

Two figures get quoted for house prices around here and they point in opposite directions. The official Wealden average is £389,000, and it fell over the past year. The typical home actually sold in Crowborough went for £437,500. Both are correct. The district stretches from Ashdown Forest down to Polegate and takes in Hailsham, which is a much cheaper market, so the district average is not the Crowborough number and never was.

This page gives both, says exactly where each comes from, and breaks Crowborough’s year of sales down by property type and by postcode area across the district.

The district figure

The average home across Wealden sold for £389,000 in May 2026, the latest provisional month, down 1.0% on the £392,000 recorded a year earlier. That comes from the UK House Price Index, which is built from completed HM Land Registry sales rather than asking prices and is adjusted for the mix of homes sold.

For context, the South East average was £381,000 in the same month, up 1.2%, and the UK average was £271,000. So Wealden sits marginally above its own region and about £118,000 above the UK, and it is one of the few districts in the South East where the annual change was negative.

The Crowborough figure

Narrow the lens to TN6 and the number goes up. Of the 282 residential sales in the TN6 postcode that HM Land Registry had registered for the year to 31 July 2026 when we checked on 9 August, the median price paid was £437,500 and the mean was £487,221.

TN6 is a clean geography for this. It covers Crowborough and Jarvis Brook and nothing else, and it sits wholly inside Wealden, so it can carry a town figure without borrowing sales from a neighbouring district. Several of the district’s other outcodes cannot: TN22 is shared with Lewes, TN21 with Rother, RH18 with Mid Sussex.

The £48,500 gap between the town median and the district average is not a contradiction. The district average is mix-adjusted across the whole of Wealden and is pulled down by Hailsham and Polegate. The Crowborough median is a plain middle-of-the-sales number for one postcode. Different method, different geography, both true.

Crowborough prices by property type

Land Registry records every completed sale with its property type, so the town’s year splits cleanly.

The share column is where the town’s price comes from. Detached houses were 43% of every Crowborough sale last year, and terraces only 11%. That is an unusual mix for a town of this size, and it is the single biggest reason Crowborough reads dearer than the district it sits in.

Compare like with like and the difference shrinks a long way. Crowborough’s detached median of £577,500 is slightly under the district’s mix-adjusted detached average of £589,000. Its semis at £395,000 are above the district’s £350,000 and its terraces at £323,750 are above the district’s £288,000, but nothing in that list is a different world. Crowborough is not an expensive town so much as a town made mostly of the expensive kind of house.

The flat market is the outlier in the other direction. A £196,250 median across 44 sales is roughly £240,000 below the town’s all-types figure, and it is the only realistic way into ownership here without help. Wealden’s first-time buyer average was £295,000 in May 2026, against £460,000 for home-movers.

The district, postcode by postcode

Median sold price by postcode area across the Wealden district, year to 31 July 2026 Seven postcode areas ranked by median price paid. RH18 Forest Row is highest at 490,000 pounds from 43 sales, level with TN5 Wadhurst and Ticehurst, also 490,000 from 81 sales, though TN5 spreads across four districts. TN6 Crowborough is 437,500 from 282 sales. TN22 Uckfield and Buxted is 410,833 from 318 sales. TN21 Heathfield is 385,000 from 213 sales. BN26 Polegate and Alfriston is 320,000 from 161 sales. BN27 Hailsham and Hellingly is lowest at 310,000 from 397 sales. Crowborough is dear for Wealden, but not the dearest Median price paid by postcode area, sales registered 1 Aug 2025 to 31 Jul 2026. Source: HM Land Registry Price Paid. RH18 Forest Row £490,000 TN5 Wadhurst area * £490,000 TN6 Crowborough £437,500 TN22 Uckfield, Buxted £410,833 TN21 Heathfield £385,000 BN26 Polegate, Alfriston £320,000 BN27 Hailsham £310,000 * TN5 spans four districts, so only some of those 81 sales are in Wealden. TN6, BN27 and BN26 sit wholly inside it.

The pattern is the one you would guess from the map. The northern end of the district, up in the High Weald and within reach of Tunbridge Wells and the Oxted line, is the expensive part. The southern end, closer to Eastbourne, is not. Hailsham had 397 sales, more than any other outcode here, at a £310,000 median, and it is where most of the district’s new housing is going.

Sale counts matter as much as the medians. Forest Row’s £490,000 comes off just 43 sales, so one unusual house moves it noticeably. Crowborough’s £437,500 comes off 282, and Uckfield’s £410,833 off 318, which makes those two the most reliable numbers on the chart.

What each source actually measures

  • UK House Price Index (the £389,000): every completed sale in the district, mix-adjusted so that a month full of big detached sales does not fake a price rise. Published monthly, revised for several months afterwards, so the May 2026 figure is provisional.
  • Land Registry Price Paid (the £437,500 and everything in the tables): the raw record of every completed sale, queried here by postcode district over a fixed twelve-month window. No mix adjustment, so the mix in the table above is doing real work.
  • Neither is an asking price. Portal averages usually run higher because they measure what sellers want, not what buyers paid.

Registration lags completion by a few weeks, so the most recent month in any Price Paid query is always incomplete. That is why the window here ends on 31 July 2026 rather than today.
