Buying a Plot of Land: What to Check Before You Offer (2026)
The planning checks that decide whether a plot is buildable, the constraints that catch buyers out, and how to avoid paying for land you cannot develop.
The short answer
A plot is only worth what you can build on it. Before you make an offer, you need to know its planning status, the constraints that affect it, and whether you can physically access and service it. Land sold as a "building plot" does not always have planning permission, and an attractive price often reflects a problem the seller already knows about. The checks below separate a genuine opportunity from an expensive mistake.
A Homeowner Planning Review runs these checks on a plot for £249 in 48 hours, so you can offer with your eyes open rather than after you have committed.
Does it actually have planning permission?
Find out exactly what consent exists. The strongest position is a current full planning permission for the scheme you want. Outline permission establishes the principle but leaves the detail (the reserved matters) to be approved later. A permission can also have expired, or come with conditions that are expensive to discharge. Land with no permission at all is the highest risk: you are buying on the hope of a future consent that may never come.
Check the planning history
A history of refusals or withdrawn applications tells you how the council views development here. If similar schemes have been refused, understand why before you assume yours will succeed. The planning history sits on the council's online register.
The constraints that decide buildability
- Green Belt and designations. Green Belt, Areas of Outstanding Natural Beauty, and National Parks heavily restrict new building.
- Flood risk. A plot in a higher flood zone faces a tougher test and may be undevelopable for housing.
- Heritage. Conservation areas, listed buildings, and their settings shape, and sometimes prevent, what you can build.
- Trees and ecology. Protected trees and protected species can constrain the footprint or add cost and delay.
- Ground conditions. Contamination history, former mining, and poor ground can add significant abnormal costs.
Access, services, and legal title
Confirm you have a legal right of access to the plot from the public highway. A plot with no access, or one that depends on a strip of land someone else owns (a ransom strip), can be worthless or expensive to unlock. Check whether mains water, drainage, electricity, and other services are available and what connecting them would cost. Ask your solicitor about restrictive covenants, which can limit or prevent building regardless of planning.
Budget for the levies
New homes can attract the Community Infrastructure Levy and planning obligations. Factor these into your numbers before you offer, not after.
Check before you offer
Most of these issues are visible from desktop evidence before you commit a penny of the purchase price.
