What homes sold for in UB5

What the figures mean for land in Northolt

3% of postcodes in UB5 are inside the Green Belt, so Northolt has land both inside and outside it. Which side of the boundary a plot sits on determines whether the Green Belt tests apply to it at all.

These are district-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.

Questions landowners ask about Northolt

Can I build on land I own in Northolt?

It depends on where the plot sits, not on the district average. In UB5, 3% of postcodes are in the Green Belt, 1% in a conservation area. On Green Belt or National Landscape plots a new home is the exception and needs a specific case; a replacement dwelling, a conversion or a modest extension is usually the realistic route there. 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. A plot on the edge of a village or town with access has the best chance; an open field outside the settlement boundary rarely gets consent for housing whatever the market is doing.

Do I need planning permission for an outbuilding, extension or change of use in UB5?

Often, yes. 2% of postcodes in UB5 are under an Article 4 direction (1 separate direction), which withdraws particular permitted development rights, so an outbuilding, extension or change of use that is automatic elsewhere needs an application there. Outside those areas, permitted development applies to houses and their gardens but not to agricultural land or paddocks, where a new building or a new use normally needs permission or prior approval.

Will a developer be interested in a plot in Northolt?

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 UB5 the median sale is £421,500, and only 1% 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.

What is a plot of land worth in Northolt?

There is no district 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 UB5 would be measured against a £421,500 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.

How do I find out what applies to my own plot in Northolt?

Three places: Ealing's local plan and its policies map for the settlement boundary and allocations, the council's planning register for what has been approved or refused on neighbouring land, and planning.data.gov.uk for the national designations. That is an evening's work if you know what you are looking for. The alternative is to draw your boundary on this site: an architect checks it against the same records and writes back within 48 hours with a plain answer, free and without obligation.
