How to Buy Land with Planning Permission
If you’re thinking about building your dream home, having a plot with planning permission already in place gives you a great head start. Recent figures show that there were over 4,300 permissions granted across England in just 12 months, showing the sheer scale of opportunity there is for buyers.
However, even with this permission in your possession, there are some hurdles you’ll still have to clear. To buy land with planning permission, you must verify the Decision Notice, check for restrictive covenants, confirm utility access, and ensure any Overage Agreements are reviewed by a specialist solicitor.
How to Buy Land with Planning Permission
One of the great things about having permission in place already is that you’re so much closer to your dream home than without it.
It can involve a long, drawn-out process, so not having to go through the application is a real bonus. All that said, permission being there is a starting point, not a finish line, meaning there are lots of other things you need to think about.
The following considerations are crucial:
Ground conditions
Planning permission says nothing about what's under the ground; while a home survey tells you what’s going on under the roof, a land survey does the same for the ground it’s being built on.
Utilities and services
You’ll need to find out whether water, electricity, gas, and broadband are already connected, and cost them out, if they're not.
Access to the plot
There must be access to the land via roads or lanes, because if construction equipment can't drive in easily, your timeline will lengthen before work even starts.
Local development plans
You could find roads, rezoning, or even other new builds nearby, changing the area's character and affecting your privacy, views, and the finished home's value.
Financial planning
It’s not wise to only have ‘just enough’ budget for your new home project because there are pretty much always unexpected costs at some point when buying land with planning permission. A general rule of thumb is to set aside at least 10% of the budget for unexpected costs.
Overage Agreements
You will likely pay more for land with planning permission. Buying land without planning permission often involves an 'overage agreement', which means you'd have to pay the seller a share of the uplift in value once permission is granted.
Community Infrastructure Levy
The levy helps to fund regional infrastructure and is payable as soon as you commence the build. The good news is that, as a self-builder, you are usually exempt. You must follow the application process for exemption exactly, as starting work too early or submitting the forms a day late could mean paying the levy in full, costing you thousands of pounds.
With a good conveyancer in your corner, you’ll be guided through every stage of the purchase, from checking contracts to completing the sale. It’s the only sensible way to ensure your self-build goes as smoothly as possible.
How to spot 'good' planning permission
Planning permission may be outline or full permission, and even full permission has an expiry date.
Outline planning permission
This only approves that the land can be developed. You will still need to apply for 'reserved matters' approval, which may be refused based on your design. You have more flexibility, but check which types of developments have been approved locally to gauge whether your plans are realistic, as you don't want to find out after purchase that you still can't build your dream home.
Full planning permission
This is ideal, but it limits you to following the existing design or reapplying if you want to make major changes. Lenders prefer full planning permission and are more likely to grant you a self-build mortgage. Full planning often still comes with 'Pre-commencement Conditions' like archaeological surveys of the land, which have to be met before work can begin.
Expiry dates
Planning permission usually lasts for three years. Check the 'Decision Notice' date to see how long you've got to get the build underway. Just because planning has been approved in the past doesn't mean it will be renewed, especially if there have been other developments in the area that have added to the infrastructure burden.
How to Find Land for Sale with Planning Permission
Once you’ve made the decision to try a self-build, finding the right plot is nothing like browsing for a home on Rightmove. The reality is that the best plots aren’t often listed publicly, meaning it’s about knowing where to look, plus what to do when you find something that looks interesting.
Naturally, after finding something, you’ll look at all the factors in the previous section, but here are a few places to start looking.
Specialist land agents
Property portals
Council self-build registers
Developers
Auction Houses
Networking with local builders or architects
There are agents who deal exclusively in plots and self-build land. They tend to know what's coming to market before it gets listed anywhere publicly, which matters when the best plots go fast.
Sites like Rightmove and Zoopla both have filters that let you search specifically for land with planning permission, which cuts out a lot of noise from the wider results.
Local authorities are required to keep track of people wanting to self-build, and many maintain lists of serviced plots. Some councils' self-build registers will even put you in touch with landowners directly.
On some of the larger housing developments, individual plots with permission sometimes get sold off separately. It's worth checking developer websites if you're open to building within a wider development.
Permitted land does come up at auction occasionally, but it’s always a good move to go through the legal pack
People working in the area regularly hear about plots before anyone else does.
Tracking down the right plot takes patience, but it's often time well spent. Once you've found your plot and had your offer accepted, a conveyancer can go through the legal title and contracts and tell you straight whether anything is likely to cause you grief.
Where is Cheap-to-Buy Land with Planning Permission?
Parts of northern England, incliding Burnley and Hull, have the lowest entry points for development land. Lincolnshire and County Durham have large pockets of land with planning permission for sale, due to lower competition from commercial developers.
Region | Typical Plot Price (with Permission) |
| Scotland (Rural) | £70,000 – £120,000 |
| North East England | £85,000 – £150,000 |
| Midlands | £150,000 – £300,000 |
| South East | £450,000+ |
Affordable land with planning permission exists, but it takes an ever-keener eye to locate. Prices vary a lot depending on where you are in the country, as well as on factors like local demand and whether the plot in question has any utilities already connected.
As a rule, plots in the countryside (i.e. away from big cities) tend to cost a lot less than those in established townships or places on the commuter belt.
How to find cheaper land for building on
- Look further from city centres - Plots for sale in smaller towns and villages regularly come in at a fraction of the price of equivalent land in high-demand areas, just like with house purchases.
- Look at plots needing work – Land that hasn’t yet been connected up to utilities or needs access improvements/ground preparation often sells for less because buyers factor in the extra effort and cost.
- Consider plots with outline rather than full permission – These can be priced lower because there’s still design work and approvals to finalise.
Keep in mind that a low asking price doesn't always stay low once you start adding everything up. Utilities, access improvements, surveys, and legal fees all go on top, turning a ‘bargain’ into a market-rate opportunity.
