Applying for planning permission can be a tense time, especially when you’re anticipating a much-needed home improvement project or building your own home. An application for planning permission will add to not only how long it takes for your project to get started, but potentially the stress of the build too, especially when you’re dealing with some contentious planning issues. 

Whether you’re planning a self build, making an extensive addition to your existing home or looking to make changes to a listed building or a property in a designated area, understanding the planning process is a great way to keep abreast of how to succeed with your proposal.

In our essential guide, you’ll find everything you need to know, including the best ways to apply for planning permission, how long it will add to your build and the costs involved. 

What is Planning Permission?

Planning permission refers to consent from your local authority for a proposed building, which is in place to deter inappropriate developments. It's usually required when building a new dwelling or making extensive changes to an existing one. 

Planning permission is also often the key that turns a piece of agricultural land into a viable building plot.

Decisions on whether to grant planning permission are made in line with national guidance (in the form of the National Planning Policy Framework) and the local planning policies set out by the local authority.

The Planning Hub is a new online resource that will help you understand how to get to grips with complex planning rules. Join today for access to easy-to-read guides which will provide you with key information to help you secure planning permission. 

The cost of submitting a planning application varies across the UK, but is currently £462 for a full application for a new single dwelling in England. For home improvers, an application in England for an extension currently costs £206, whereas in Wales the cost of a typical householder application is currently £190.

if you're granted planning permission subject to planning conditions, further costs will be incurred in approving details and materials, at a cost of £116 per application (though multiple conditions can be combined in a single application).

Since April 2008, all local planning departments use the same application form, known as 1APP, you can find the appropriate form for your area and complete the application process online at the Planning Portal.

However, the real cost of obtaining planning permission arguably comes in preparing the plans and documents (the design fees) in readiness for submission and any accompanying surveys (such as ecological surveys) which may be required. Also bear in mind that you may need to make more than one planning application in order to reach agreement with the council and make revisions to your plans accordingly (which may involve further architect/designer fees).

A minimum budget of around £2,000 is probably realistic for getting planning permission.

How Long Does Planning Permission Last?

What is a Material Start?

While planning regulations don't dictate what a material start is precisely, it's usually assumed to be where you submit a Building Control application to dig and pour the foundations. An inspection by Building Control will prove the start date of the build. 

All planning permissions automatically expire after a certain period. Unless your permission says otherwise, you have three years from the date full consent is granted to begin building.

Depending on how soon your consent expires, you may take different steps to get your project started. If the expiry date is imminent, it may be best to reapply to ensure you have adequate time to plan effectively.

If you have sufficient time to make what is known as a ‘material start’ then it may be best to secure the permission in perpetuity, allowing you the time needed to get started properly.

Avoid buying a plot with planning permission that is about to expire — consent will expire before you have chance to get started. This is especially relevant on consents that were hard fought or where planning policy may have changed. Securing new permission may not always be possible. 

How Do I Know if I Need Planning Permission?

If your project involves the creation of a new dwelling (by either building from scratch or subdividing an existing home), then planning permission is normally required.

Larger outbuildings or extensions, or builds/improvements in designated areas or involving listed buildings, are also likely to require planning permission.

Smaller additions and improvements can normally be made under Permitted Development.

What are the Different Types of Planning Permission?

This grants permission for a project with a detailed design. But before going full steam ahead on site, the planning conditions attached to the consent must be discharged. They must be discharged (satisfied) formally by letter by the local authority, usually before commencing work — otherwise the approval is invalidated.

This grants permission in principle, but does not include design specifics. It is important to note that outline planning consent does not provide permission to start work. An application for ‘reserved matters’ — which may include the size of the proposed house, appearance, position, landscaping and access — will need to be submitted and approved before work can take place.

If your detailed plans deviate significantly from the original outline permission then you’ll likely need to submit for full planning.

Also, if you are keen to start your project quickly, then it makes sense to apply for full planning permission.

How Long Does it Take to Get Planning Permission?

You should find out whether your application has been approved after eight weeks — although more complex schemes can take longer.

A sign is posted outside the address relating to the proposed development and any neighbours likely to be affected are written to and invited to view the plans and to comment. This is known as the public consultation process and it takes three to eight weeks. The authority will make statutory consultations to the local Highways department, and where necessary the Environment Agency as well as others.

Realistically, if you are having to make more than one application (following revisions or changes to the design), you should consider setting aside 18 months for the process.

Securing planning permission doesn’t necessarily mean that you can start work straightaway. Make sure you look at the planning conditions attached to the consent — for instance, you may need to seek approval for your chosen cladding or roofing materials.

Should I Use a Consultant for Planning Permission?

Many people will appoint a planning consultant before they even buy a plot, to work out the potential of a development. This could save you thousands of pounds on buying a project that turns out not to be feasible.

Planning consultants have full knowledge of the ever-changing planning policies that any project will be subject to. So, whether you are extending, renovating or building a new home, their help could be indispensable — especially if your project is in a designated area of which carries restrictions such as a Conservation Area or AONB.

What's Included in a Planning Application?

In general terms, your application should include:

  • five copies of application forms
  • the signed ownership certificate
  • a site plan, block plan, elevations of both the existing and proposed sites,
  • a Design and Access Statement
  • the correct fee.

These statements have to accompany all planning applications besides householder building works in unprotected areas and changes of use. Statements are used to justify a proposal’s design concept and the access to it. The level of detail depends on the scale of the project and its sensitivity.

Most authorities will have guidance notes available to help you but, unfortunately, unless you ensure you have included a statement in your submission, planning authorities can refuse to register your planning application.

What Factors Affect the Granting of Planning Permission?

The local authority will base its decision on what are known as ‘material considerations’, which can include (but are not limited to):

  • Overlooking/loss of privacy
  • Loss of light or overshadowing
  • Parking
  • Highway safety
  • Traffic
  • Noise
  • Impact on listed building and Conservation Area
  • Layout and density of building
  • Design, appearance and materials
  • Government policy
  • Disabled access
  • Proposals in the development plan
  • Previous planning decisions
  • Nature conservation

(MORE: How to Get Planning Approval)

Neighbours will be consulted and invited to comment, together with parish councils (in England and Wales), but only those objections based on material considerations are taken into account.

If the neighbours do not object and the officers recommend approval, they will usually grant planning permission for a householder application using what are known as delegated powers.

Like it or not, when you build things, you risk upsetting people. It may not be rational, but people get very emotional about changes that they fear will affect their home, their view or their property’s value – or even just the street they live on.

So it pays to be polite, to talk to the neighbours and to show them the plans. If you can accommodate minor changes without undermining your goals then it might be worth doing if it could help avoid local objections.

If there are objections or the application is called into a committee by one of the local councillors, then the decision will be made by a majority vote by the local planning committee. At the planning meeting, you or your agent will be given an opportunity to address the planning committee, but this time is limited to a maximum of three minutes.

Face-to-face meetings can be helpful in thrashing out the justification for objections Requests for changes should be based on planning policies and they should be consistent with other recent decisions in the area.

Can I Make Changes to my Design When Planning Permission is in Place?

Before a judgement has been made on your planning application, you can withdraw it at any time — so if you think you are going to get a refusal, you can withdraw it at any time up to the day itself, and resubmit free of charge. 

Once planning permission has been approved, you can make minor alterations by applying for a non-material amendment. However, major alterations could involve a further application for full planning permission, so discuss your plans with your LPA first.

What Happens if I am Refused Planning Permission?

In England, around 75% of applications are granted. If your application is rejected, you can either amend and resubmit having dealt with the reasons for refusal, or you can make an appeal to the planning inspectorate.

Around 40% of householder applications that are refused are later granted at appeal.

Can I Build a House Without Planning Permission?

While it is not illegal to develop land without planning permission, it is not lawful and, consequently, if you have failed to get consent for your project, then the local planning authority can take action to have the work altered or demolished. In this instance, you can make a retrospective planning application and if this is refused you can appeal the decision. If you lose, it can prove very costly.

There is a legal loophole: if no enforcement action is taken within four years of completion, the development becomes immune from enforcement action (10 years for a change of use). The development then becomes lawful — but this is too great a risk to take.

Altering a listed building without prior permission is, however, a criminal offense, and in extreme cases it can lead to prosecution and unlimited fines — and even imprisonment. So do ensure you apply for approval first.

Can I Get Planning Permission for a Home in the Countryside?

Many believe it is harder to get planning permission if you are building a home in the countryside. However it certainly isn’t out of the question as our guide to planning permission in the countryside explains.

In fact, under Paragraph 79 (formerly Paragraph 55) of the National Planning Policy Framework, it is even possible to build in green belt land, if your project can be shown to be of particular architectural merit and worth.

Can You Make a Planning Permission Application on Land or a Home You Don't Own? 

You can make a planning application on any piece of land in the country — you don’t have to own it. 

You can submit an infinite number of planning applications on any one site — and choose which one to use. As long as it is current, you don’t have to use the most recent
