IS PLANNING PRE-APPLICATION ADVICE WORTH IT?
When a planning pre-app is worth the time and cost — and when it may not be
Planning pre-application advice can be extremely useful, but it is not automatically worth doing for every development.
A pre-app allows you to seek the local planning authority's initial view before submitting a formal planning application. It can help identify objections, test the principle or scale of development and highlight information that may be needed later.
However, pre-application advice costs money, takes time and does not guarantee that planning permission will ultimately be granted.
The key question is therefore not simply:
“Should I get a pre-app?”
It is:
“What uncertainty will the pre-app help resolve, and is the answer worth the additional time and cost?”
WHAT ARE THE BENEFITS OF PRE-APPLICATION ADVICE?
The principal benefit is the opportunity to identify planning issues before committing to a full application.
Depending on the site, a useful pre-app might help establish:
Whether the principle of development is likely to be supported
Whether the proposed amount of development appears appropriate
Whether the scale and layout need changing
Whether the design approach raises concerns
Whether access is likely to be problematic
Which planning policies are particularly important
What technical information may be required
This can allow the proposal to be revised before the formal application is submitted.
On a substantial development, identifying a significant problem early can potentially save far more than the cost of the pre-app itself.
WHAT ARE THE DISADVANTAGES OF A PRE-APP?
There are also limitations.
A pre-app:
Costs money
Adds another stage to the programme
Can take time to obtain
Does not provide planning permission
Does not guarantee the outcome of a later application
May provide relatively cautious or limited advice
Can identify additional work the authority wants to see
The quality and scope of pre-application services also vary between planning authorities.
This means the value of a pre-app depends heavily on what you need to learn from it.
WHEN IS A PRE-APP WORTH IT?
A pre-app tends to be more useful where there is a genuine planning question that could materially change what happens next.
For example:
The principle of development is uncertain
If there is a genuine question about whether the proposed development is acceptable in the location, obtaining the authority's initial view may be useful before progressing detailed work.
You are unsure how much development the site can accommodate
A pre-app can sometimes help test whether the authority considers the proposed scale or density appropriate.
The site is sensitive
Heritage, landscape, design or other contextual issues may make early discussion worthwhile.
The proposal is substantial
As the potential development value and cost of preparing an application increase, resolving significant planning issues earlier can become increasingly valuable.
There are several possible development options
If the authority's view could influence which option is progressed, early engagement may prevent detailed work being undertaken on the wrong scheme.
WHEN MIGHT A PRE-APP NOT BE WORTH IT?
There are also circumstances where proceeding directly to a planning application may be more appropriate.
For example, where:
The planning principle is well established
The proposal is straightforward
Planning policy is relatively clear
Similar development has already been approved nearby
The application can be prepared without substantial upfront expenditure
The pre-app is unlikely to answer anything that cannot already be reasonably established
Timing is particularly important
This does not mean a pre-app would provide no information.
The question is whether the information is sufficiently valuable to justify introducing another stage.
IS A PRE-APP WORTH IT FOR A SINGLE HOUSE?
Sometimes.
The fact that a proposal is small does not necessarily mean the planning issues are simple.
A single dwelling on a straightforward infill plot may not require pre-application engagement if the planning position and design parameters are reasonably clear.
But one house on a difficult rural, backland or constrained site could involve substantial planning uncertainty.
The decision should therefore be based on planning risk rather than simply the number of homes proposed.
IS A PRE-APP WORTH IT FOR GARDEN DEVELOPMENT?
It can be.
For a garden site, important questions might include:
Is another dwelling acceptable in principle?
Does the authority consider the proposal to be appropriate infill or backland development?
Is the proposed scale acceptable?
Are relationships with neighbours likely to cause concern?
Is the access arrangement likely to be acceptable?
However, it is often worth undertaking an independent planning and development assessment first.
There is little value in paying the council to identify obvious problems that could have been identified beforehand.
IS A PRE-APP WORTH IT FOR LAND OUTSIDE A SETTLEMENT BOUNDARY?
Potentially, but this requires particular care.
If the site conflicts with the normal spatial strategy for development, the fundamental planning issue may already be apparent from policy.
A pre-app might still be useful where there is a credible planning argument that needs testing.
But it should not be used as a substitute for first understanding the policy position.
Before approaching the council, it is worth establishing:
What is the policy conflict?
Is there a credible reason why development might nevertheless be acceptable?
What evidence supports that case?
What exactly do we want the council to respond to?
That produces a much more useful pre-application exercise than simply submitting a red line around a field and asking whether houses could be built.
IS A POSITIVE PRE-APP WORTH HAVING?
Yes, where it provides meaningful support for the development strategy.
A positive response can provide confidence to:
Progress detailed design
Commission technical consultants
Submit a planning application
Continue with a land acquisition
Explore funding or development options
However, it remains advice rather than planning permission.
A subsequent application will still need to be considered through the formal planning process.
A positive pre-app should therefore be used to inform and strengthen the next stage, rather than treated as a guaranteed consent.
CAN A NEGATIVE PRE-APP STILL BE VALUABLE?
Absolutely.
Sometimes a negative response is more commercially useful than an encouraging but vague one.
Imagine spending substantial sums on architectural drawings, highways work, drainage, ecology and other reports before discovering that the planning authority has a fundamental objection to the principle of development.
Identifying that issue earlier could prevent significant wasted expenditure.
A negative response can also reveal whether the problem relates to:
The principle of development
or
The particular scheme proposed.
That distinction is important.
If the principle is acceptable but the design is not, there may be a clear route towards revising the proposal.
If the objection is fundamental, the development strategy may need to change entirely.
DOES A POSITIVE PRE-APP GUARANTEE PLANNING PERMISSION?
No.
Pre-application advice does not bind the local planning authority's subsequent decision.
A formal application may involve further information, consultation responses and planning considerations that were not available at pre-app stage.
The proposal itself may also evolve.
A positive pre-app should therefore be considered useful evidence and planning intelligence, rather than a planning consent.
HOW MUCH SHOULD I SPEND ON A PRE-APP?
The council's fee is only part of the cost.
You also need to consider how much professional work should be undertaken before making the enquiry.
At one extreme, submitting too little information can result in vague advice.
At the other, spending heavily developing a near-complete planning application defeats some of the purpose of testing the proposal early.
The appropriate level of work should reflect the question being asked.
For example:
Testing the principle of one dwelling
may require relatively limited design information.
Whereas:
Testing the scale, massing and layout of a larger development
may require a much more developed proposal.
The objective should be to provide enough information to obtain a meaningful answer without unnecessarily designing the entire scheme.
SHOULD I DO A FEASIBILITY STUDY BEFORE A PRE-APP?
Often, yes.
A feasibility assessment can help establish:
Relevant planning policy
Planning history
Comparable nearby decisions
Development capacity
Access
Major constraints
Potential planning arguments
Areas of uncertainty
This allows the pre-app to focus on the issues where the council's view is actually valuable.
A useful sequence can therefore be:
Planning research
↓
Development feasibility
↓
Identify unresolved planning questions
↓
Pre-application advice, if useful
↓
Refine the proposal
↓
Planning application
Not every project needs every stage.
The point is to move forward by progressively reducing uncertainty.
SHOULD I USE A PRE-APP INSTEAD OF MAKING A PLANNING APPLICATION?
Usually, they serve different purposes.
A pre-app provides advice.
A planning application seeks a formal decision.
If you already have enough information to prepare a strong application and there is little to be gained from another stage, proceeding directly to an application may make sense.
If there is a fundamental question that could substantially alter the proposal, obtaining advice first may be more efficient.
The decision is therefore about planning strategy and risk management, not simply procedure.
HOW DO I GET THE MOST VALUE FROM A PRE-APP?
Don't simply send the council a proposal and ask what they think.
A stronger approach is to:
Understand the planning position first
Know the relevant policies, history and constraints.
Develop a credible proposal
Give the authority something meaningful to consider.
Identify the key uncertainties
Know what you actually need their view on.
Ask specific questions
Make it easier for the planning officer to provide useful responses.
Use the response
Adapt the planning and design strategy rather than treating the pre-app as an administrative exercise.
The value comes from how the advice affects the next decision.
SWAP VIEW
We would not automatically recommend a pre-app just because a council offers one.
Before spending the client's money, we ask:
What do we already know?
What don't we know?
Can we answer it ourselves?
If not, could the council's answer materially change what we do next?
If the answer to the final question is yes, a pre-app may be extremely valuable.
If we already understand the planning position and the council's response is unlikely to alter the proposal, there may be little benefit in paying for another stage and waiting for an answer.
The purpose of a planning strategy should be to reduce the important uncertainties as efficiently as possible.
Sometimes a pre-app is exactly the right tool.
Sometimes it isn't.
NOT SURE WHETHER A PRE-APP IS WORTH IT?
If you have a development site and are deciding whether to seek pre-application advice or proceed directly towards a planning application, SWAP can help assess the planning position first.
We can review the site, planning policy, planning history and principal constraints, consider what development might realistically be achievable and identify whether there are specific questions worth putting to the local planning authority.
Send us the site address or location, any plans you have and a brief description of what you're considering.
