Planning Application Fees Are Increasing in December 2026: What Norfolk Homeowners and Developers Need to Know
Published: 12 November 2026 | Ikonic Architecture
If you're planning a house extension, building a new home or considering a small residential development, there is an important change approaching.
From 8 December 2026, planning application fees across England will increase, affecting homeowners, self-builders, landowners and property developers.
The revised charges will apply nationally, including applications submitted to South Norfolk, Broadland, Breckland, North Norfolk, Norwich and East Suffolk councils.
There is also another increase scheduled for 1 April 2027, when fees will rise by a further 3.5%.
Although planning application fees are only one part of a project's overall cost, understanding them early can help avoid unexpected expenses and make better decisions about how to progress a proposal.
How Much Will Planning Applications Cost from December 2026?
The revised fees vary depending on the type and scale of development.
For homeowners and smaller developers, some of the most relevant charges include:
Application type | New fee from 8 December 2026 |
Householder extension or alteration to one dwelling | £575 |
Ancillary outbuilding or qualifying works within a dwelling's curtilage | £285 |
Full planning application for one new dwelling | £752 |
Full planning application for two new dwellings | £1,504 |
Outline planning application for a residential site below 0.5 hectares | £719 per 0.1 hectare or part thereof |
Permission in Principle | £825 |
Discharge of planning conditions, householder | £125 |
Discharge of planning conditions, other development | £435 |
Non-material amendment, householder | £53 |
Non-material amendment, other development | £360 |
These are the statutory application fees, not architectural design fees. Other charges, including any applicable Planning Portal service charge, specialist reports or consultant fees, may need to be budgeted separately.
The correct fee will depend on the application category and circumstances.
What Does This Mean for Homeowners Planning an Extension?
For a typical householder planning application, the new fee will be £575.
This applies to many proposals involving extensions or alterations to an existing single dwellinghouse where planning permission is required.
However, not every extension requires a householder planning application.
Some extensions can be undertaken under permitted development rights, provided they meet the relevant limitations and conditions.
Other projects may benefit from an application for a Lawful Development Certificate, which can provide formal confirmation that proposed works are lawful.
Before preparing an application, it is worth establishing:
Whether planning permission is actually required.
Whether the proposed extension falls within permitted development rights.
Whether the property is affected by restrictions, including an Article 4 Direction or planning conditions.
Whether a different application route would be more appropriate.
Choosing the correct route at the outset can reduce unnecessary costs and help avoid delays.
Our advice: Don't assume that a planning application is required simply because you're extending your home. Establish the planning position before committing to detailed drawings.
Planning a Self-Build Home in Norfolk?
For those looking to build their own home, the revised fees are another cost to consider when assessing a potential plot.
A full planning application for a single new dwelling will cost £752 from 8 December 2026.
However, there may be circumstances where an outline planning application or Permission in
Principle is a more appropriate first step.
For example, a landowner considering a garden plot or a small parcel of land may want to establish whether residential development is acceptable before investing in a fully developed design.
An outline application for a residential site below 0.5 hectares will be charged at £719 for each 0.1 hectare, or part thereof.
This means a site measuring 0.15 hectares would attract an outline application fee of £1,438.
Importantly, outline permission does not remove the need for subsequent approvals. Reserved matters applications may involve additional fees.
Our advice: The cheapest application fee does not necessarily mean the most cost-effective planning strategy. The right approach depends on the site, planning policies, access arrangements and the level of certainty needed before further investment.
Small Developers: Why Planning Strategy Matters More Than Ever
For small residential developers, planning fees can quickly become a significant upfront expense.
Under the revised charges, full planning applications for developments of fewer than ten dwellings will cost £752 per dwelling.
For example:
Proposed development | Planning application fee |
1 dwelling | £752 |
2 dwellings | £1,504 |
3 dwellings | £2,256 |
5 dwellings | £3,760 |
9 dwellings | £6,768 |
These figures exclude other development costs.
Depending on the site, additional expenditure could include ecological assessments, highways advice, drainage strategies, arboricultural reports and other technical information.
This makes early feasibility work particularly valuable.
Before committing to a planning application, it is worth reviewing:
The site's development potential and relevant planning policies.
Access, visibility and parking requirements.
Potential constraints affecting the number and arrangement of dwellings.
Whether an outline, full or alternative planning route is most appropriate.
The likely cost of supporting reports and surveys.
A relatively modest investment in feasibility work can help identify significant constraints before substantial design and application costs are incurred.
What About Barn Conversions and Class Q Applications?
For rural landowners considering the conversion of agricultural buildings, the updated fees also affect certain prior approval applications.
Under the revised schedule, applications involving changes of use under Part 3 Classes M, N and Q will generally attract:
£310 for the relevant prior approval application.
£667 where the application includes building operations in connection with the change of use.
Class Q can offer opportunities to convert qualifying agricultural buildings into residential accommodation without a conventional full planning application.
However, the regulations contain detailed eligibility criteria, limitations and conditions.
Not every agricultural building qualifies, and the fact that a building exists does not automatically mean residential conversion will be permitted.
Our advice: Establish whether the building and proposed works meet the relevant Class Q requirements before commissioning a detailed conversion scheme.
Will Planning Fees Increase Again in April 2027?
Yes.
The December 2026 fee changes will be followed by a further 3.5% increase on 1 April 2027.
This is particularly relevant to projects still at the early design or feasibility stage.
However, submitting an incomplete or poorly coordinated application simply to avoid a future fee increase may prove counterproductive.
Planning applications need to be supported by appropriate drawings, documentation and technical information.
An application that cannot be validated promptly, or which requires substantial amendments, may create delays and additional professional costs.
The better approach is to establish a realistic submission programme and ensure the necessary information is prepared in good time.
Should You Submit Your Planning Application Before 8 December?
If your project is already well developed and ready for submission, it may be worth reviewing whether an earlier application is practical.
However, the submission date alone should not dictate the design or planning strategy.
Before proceeding, consider whether:
The proposed design has been properly reviewed.
The relevant planning constraints have been investigated.
The application documents are sufficiently complete.
Any necessary surveys or specialist information have been obtained.
The application route and associated fees have been confirmed.
Saving a relatively small amount on an application fee is unlikely to justify rushing a proposal that is not ready.
