Planning Permission After Building

At Planning Permission After Building, we provide specialist planning consultancy services for homeowners, landlords, developers, and businesses who need to obtain planning permission after development work has already been completed. Planning Permission After Building helps clients address unauthorised development, navigate retrospective planning applications, and resolve planning issues before they become more serious.

Many property owners only discover planning permission was required after construction has finished. This may occur during a property sale, mortgage application, planning investigation, neighbour complaint, or local authority review. While this situation can be concerning, obtaining planning permission after building work has been completed is often possible through a retrospective planning application.

Planning Permission After Building provides expert guidance throughout the process, helping clients understand planning requirements, assess risks, and secure the approvals needed to regularise completed developments.

Whether the project involves a house extension, loft conversion, garage conversion, outbuilding, commercial alteration, change of use, or larger development, Planning Permission After Building offers professional support designed to achieve the best possible planning outcome.

Why Choose Planning Permission After Building?

At Planning Permission After Building, we understand that retrospective planning matters can create uncertainty for property owners. Concerns about enforcement action, planning refusals, property transactions, and future development potential are common when planning permission has not been obtained before construction.

Our role is to assess the completed development and provide clear advice based on planning policy, local authority requirements, and the specific circumstances of the case.

Every project is reviewed against the National Planning Policy Framework (NPPF), local planning policies, supplementary planning guidance, conservation area requirements, and relevant planning legislation. This allows us to identify potential issues and prepare applications that address planning concerns proactively.

Compliance is central to the process. Planning Permission After Building helps clients understand how completed developments are assessed by planning authorities and what supporting information may be required to demonstrate compliance with planning policy.

Where appropriate, we also advise on related matters involving the Building Regulations 2010, Lawful Development Certificates, planning enforcement procedures, and planning appeals. Understanding these issues can often help property owners avoid additional complications and achieve a smoother resolution.

Many clients choose Planning Permission After Building because professional planning advice can significantly improve the chances of securing approval while reducing the risks associated with unauthorised development.

How Much Does Planning Permission After Building Cost?

The cost of planning permission after building services ranges from £500 to £10,000+.

The cost of planning permission approval after a building is complete depends on the scale of the development, planning complexity, local authority requirements, supporting documentation, and the level of consultancy support required.

Smaller residential projects such as extensions, loft conversions, garage conversions, and outbuildings often cost between £500 and £2,500 for planning assessments, application preparation, and submission support.

More complex residential and commercial developments typically range from £2,500 to £7,500, particularly where planning statements, specialist reports, negotiations, or enforcement issues are involved.

Large-scale developments, listed building matters, planning appeals, and significant enforcement cases may exceed £10,000, depending on the complexity of the project and the level of professional representation required.

Since every retrospective planning case is unique, Planning Permission After Building recommends an initial planning review before costs are confirmed.

Can You Get Planning Permission After Building Work Has Been Completed?

Planning permission can be applied for after construction has already taken place through a retrospective planning application.

The local planning authority will generally assess the development against the same planning policies that would have applied if permission had been sought before construction began. The fact that work has already been completed does not automatically mean the application will be refused.

However, planning authorities may consider factors such as visual impact, neighbour amenity, design quality, parking arrangements, environmental considerations, and compliance with local planning policies when determining the application.

Professional planning advice is often highly beneficial because retrospective applications may receive closer scrutiny than standard planning submissions.

What is the Planning Permission After Building Process?

Every case begins with a detailed planning review. Planning Permission After Building assesses the completed development, planning history, site constraints, planning policies, and any enforcement issues that may apply.

Following the assessment, we advise on the likelihood of approval and identify the most appropriate planning strategy.

Where a retrospective application is required, supporting documents, plans, planning statements, and application forms are prepared and submitted to the local planning authority.

Throughout the process, Planning Permission After Building communicates with planning officers, responds to requests for information, and provides ongoing support until a decision is reached.

If an application is refused, we can also assist with planning appeals and further planning representations where appropriate.

How Long Does Planning Permission After Building Take?

Retrospective planning applications generally follow the same timescales as standard planning applications.

Most householder applications are determined within approximately 8 weeks after validation by the local planning authority.

Larger residential and commercial applications are typically determined within 13 weeks, although more complex developments may take longer depending on consultations and planning considerations.

Planning appeals and enforcement-related matters can extend the overall process significantly.

Planning Permission After Building provides realistic timescale guidance based on the nature of the development and local authority requirements.

What Happens If Planning Permission Is Refused?

If retrospective planning permission is refused, the local authority may consider enforcement action if it believes the development causes planning harm.

Possible outcomes can include requests for modifications to the development, further planning submissions, planning appeals, or in some cases the removal of unauthorised works.

However, every situation is different, and refusal does not necessarily mean enforcement action will follow immediately. Obtaining professional planning advice is often the most effective way to understand available options and develop an appropriate response.

Why is Professional Planning Advice Important?

Retrospective planning cases often involve more complexity than standard applications because the development already exists and may be subject to planning complaints, enforcement concerns, or legal scrutiny.

Professional planning advice helps property owners understand planning risks, prepare stronger applications, respond effectively to planning authorities, and improve the chances of achieving a positive outcome.

By working with Planning Permission After Building, clients benefit from specialist planning expertise designed to resolve planning issues efficiently while protecting property value and future development opportunities.
