Land by postcode · TN area · Tunbridge Wells
Tunbridge Wells covers four postcode districts, TN1, TN2, TN3 and TN4, in Kent. Planning applications here are decided mostly by the Tunbridge Wells planning authority, with Wealden covering the rest. Below: what homes sold for, which planning controls apply, and what that means before you sell or develop a plot in Tunbridge Wells.
Residential sales recorded by HM Land Registry between 2024-08 and 2026-07 across all four of Tunbridge Wells's postcode districts. This is market context for the town, not a land valuation: what a plot is worth depends on what can be built on it, which these figures do not show.

No postcodes in Tunbridge Wells's four districts fall inside: National Park, Article 4 Direction area.
Flood zones, tree preservation orders, local plan allocations, settlement boundaries and non-designated heritage are not included here and are checked in a full assessment.
8% of postcodes in Tunbridge Wells are inside the Green Belt, so Tunbridge Wells has land both inside and outside it. The Green Belt postcodes sit mostly in TN3 and TN2. Which side of the boundary a plot sits on determines whether the Green Belt tests apply to it at all.
20% of postcodes are inside a National Landscape (AONB). In those areas national policy gives great weight to conserving landscape and scenic beauty, and major development is expected only in exceptional circumstances.
These are town-level facts. The free assessment checks your actual boundary against the same registers and the local plan and tells you plainly what they mean for your plot.
Tunbridge Wells's four districts are split between planning authorities: Tunbridge Wells (90% of sampled postcodes), Wealden (8%).
Draw your boundary, tell us what you own, and an architect checks it against these registers and the local plan. Free, no obligation, and you get a straight written answer.
It depends on where the plot sits, not on the town average. Across Tunbridge Wells, 8% of postcodes are in the Green Belt, 20% in a National Landscape and 1% in a conservation area. Green Belt land is concentrated in TN3 and TN2; on Green Belt or National Landscape plots a new home is the exception and needs a specific case, and a replacement dwelling, a conversion or a modest extension is usually the realistic route. Outside those designations the questions that decide it are whether the plot is inside or adjoining the settlement boundary in the local plan, whether it has its own road access, and what is next to it.
No Article 4 direction is recorded for Tunbridge Wells, so houses keep their normal permitted development rights for outbuildings and extensions within the size limits. Those rights do not extend to agricultural land, paddocks or a change of use to residential, which normally need permission or prior approval.
Developers look at three things before they talk about price: whether the plot is outside the Green Belt and any National Landscape, whether it sits inside or beside the settlement boundary, and what finished homes sell for. In Tunbridge Wells the median sale is £442,500, from £358,000 in TN1 to £689,950 in TN3, and only 6% of 2023–2024 sales were new-build homes, so builders have been quiet here. A single plot usually goes to a local builder or a self-builder; a site for five or more homes attracts regional housebuilders, normally through an option or a conditional contract rather than an outright purchase, so the price you see quoted is not the price you receive.
There is no town figure for land, because a plot's value comes from what can be built on it, not from where it is. As a guide, a serviced plot with consent for one house commonly sells for around a third of the finished house value, which in Tunbridge Wells would be measured against a £442,500 median sale. The same plot without consent, or inside the Green Belt, is worth a small fraction of that, and a paddock with no realistic route to consent is worth agricultural or amenity value only. The free check tells you which of those your plot is before you talk to anyone about a price.
