How to Read a Planning Application and Spot High-Value Projects
2026-08-18 · 7 min read
The practical skill that separates builders who win planning leads from those who waste time - how to read an application, judge project value, and prioritise the enquiries worth quoting.
Reading an application like a professional
A planning application contains far more than an address. The description, the scale of works, and the property details tell you the size, complexity and likely budget of the project before you ever pick up the phone.
Learning to read an application quickly is the highest-leverage skill for converting planning leads: it tells you which enquiries to chase, which to skip, and how to open the conversation with confidence.

What to look for in the description
The application description is the heart of the lead. It tells you what is being built, at what scale, and usually whether it is a simple extension or a substantial project.
- Application type: extension, loft conversion, new build, garage conversion, change of use
- Works scope: number of storeys, added floor area, new kitchens or bathrooms
- Property context: existing house size and whether the application is residential or commercial
- Applicant details and reference number for your records
Estimate project value with a simple benchmark
Build a personal benchmark table from jobs you have priced before, then slot each application into it. It does not need to be precise - you just need to sort applications into "worth chasing" and "below my minimum".
| Application type | Typical build value | Time to quote |
|---|---|---|
| Single-storey rear extension | £40,000 - £70,000 | Low |
| Two-storey extension | £80,000 - £160,000 | Medium |
| Loft conversion | £35,000 - £60,000 | Low |
| New build / substantial works | £150,000+ | High |
A rough value estimate lets you prioritise. Chase the applications that meet your minimum job size and spend your quoting time where the margin is.
Spot the high-value signal early
Certain signals mark a high-value project before you speak to anyone: a large existing property, an application that adds significant floor area, a kitchen or bathroom upgrade within the works, or a design that suggests a well-planned budget.
Conversely, be careful with applications that are clearly speculative - a change of use with no build, or a tiny extension on a property that cannot support the works. A two-minute call will confirm, but the description usually gives it away first.
Turn reading into a repeatable process
Your morning routine becomes: review the day's applications, score each on value and fit, contact the top three within the hour, and log your quotes. The scoring takes seconds once you have a benchmark, and it stops you from chasing everything that looks like work.
Builders who convert planning leads consistently are not the ones who quote every application. They are the ones who quote the right applications, fast, and with genuine knowledge of what the job involves.

Frequently Asked Questions
What should I check first in a planning application?
The application type and the scope of the works. A full two-storey extension or new build is a different job from a single-storey rear extension. The application description tells you the size and complexity before you spend a minute on the phone.
How do I estimate what a project is worth?
Use the property and the works as your guide. A larger property, a bigger extension, and added elements like a kitchen or bathroom typically mean a higher build value. Compare the application against jobs you have already priced to build a quick benchmark.
Which applications should I skip?
Skip applications outside your trade, below your minimum job size, or in areas you cannot serve quickly. Also be cautious with applications that are clearly very early stage or that look speculative - a phone call will confirm within minutes.
Is it worth contacting applicants whose application is still pending?
Yes. Most homeowners collect quotes while the application is being decided. Contacting them during that window means you can be the trusted builder who already knows the project when approval lands - rather than one of six callers the day after.
