Heritage planning is an important consideration when a development proposal involves a listed building, conservation area, historic park or garden, or another heritage asset. Changes to historic buildings and their surroundings can be subject to additional planning controls, making specialist advice valuable from the earliest stages of a project.
A heritage planning consultant can help property owners, developers and other stakeholders understand the heritage implications of a proposal, assess potential impacts and prepare the supporting information required by the local planning authority.
Whether you are planning an extension to a listed building, considering alterations to a historic property or developing land within a conservation area, understanding the heritage planning process can help you make informed decisions and reduce the risk of delays or refusal.
What Is a Heritage Planning Consultant?
A heritage planning consultant is a specialist who provides advice on the planning and heritage considerations associated with historic buildings, areas and other designated or non-designated heritage assets.
Their work can involve assessing the significance of a heritage asset, identifying potential impacts of proposed development and advising on ways to minimise or mitigate harm.
A heritage planning consultant may work alongside architects, planning consultants, surveyors, archaeologists, property owners and developers to ensure that heritage considerations are properly incorporated into a development proposal.
What Does a Heritage Planning Consultant Do?
Depending on the project, a heritage planning consultant may provide services including:
- Heritage assessments
- Heritage impact assessments
- Listed building advice
- Conservation area advice
- Planning advice for historic properties
- Assessment of the significance of heritage assets
- Advice on alterations and extensions to listed buildings
- Support with listed building consent applications
- Heritage statements
- Advice on historic parks and gardens
- Archaeological and heritage considerations
- Planning strategy and pre-application advice
- Consultation with local planning authorities
- Support during the planning application process
When Do You Need a Heritage Planning Consultant?
You may benefit from a heritage planning consultant where your proposed development could affect a heritage asset or its setting.
This can include projects involving:
- Listed buildings
- Conservation areas
- Scheduled monuments
- Registered parks and gardens
- Historic landscapes
- Historic buildings and structures
- Non-designated heritage assets
- Areas with archaeological interest
Heritage advice can be particularly valuable where a proposal involves significant alterations, demolition, extensions, changes of use or new development close to a heritage asset.
Listed Buildings
Listed buildings are protected because of their special architectural or historic interest. Works that affect their special character may require Listed Building Consent, in addition to planning permission where applicable.
A heritage planning consultant can help establish the significance of the building and assess how proposed works could affect its character and appearance.
Conservation Areas
Conservation areas are designated because of their special architectural or historic interest. Development within these areas may require greater consideration of the character and appearance of the surrounding area.
A heritage consultant can advise on how a proposal may affect the conservation area and how its design could be adapted to respond appropriately to the historic environment.
What Is a Heritage Impact Assessment?
A Heritage Impact Assessment examines how a proposed development could affect the significance of a heritage asset.
The assessment may consider:
- The history and development of the site
- The architectural and historic significance of the building or area
- The contribution made by its setting
- The nature and extent of the proposed works
- The potential impact of the development
- Measures that could reduce or mitigate any harm
The level of assessment required will depend on the nature and significance of the heritage asset and the scale of the proposed development.
Why Is a Heritage Impact Assessment Important?
A well-prepared assessment can help the local planning authority understand the relationship between the proposed development and the heritage asset.
It can also demonstrate that heritage considerations have been properly addressed during the design and planning process.
Heritage Statements for Planning Applications
A Heritage Statement may be required to support a planning application where heritage assets could be affected.
The statement should provide sufficient information about the significance of the relevant heritage asset and explain how the proposed development may affect it.
What Does a Heritage Statement Include?
Depending on the project, a Heritage Statement may include:
- A description of the site and proposed development
- The history of the property or site
- Identification of relevant heritage assets
- Assessment of architectural and historic significance
- Assessment of the setting
- Analysis of the potential impact
- Explanation of any proposed mitigation
- Conclusions regarding the heritage impact
The objective is to provide the planning authority with the information it needs to properly consider the heritage implications of the proposal.
Heritage Planning and Listed Building Consent
If your property is listed, ordinary planning permission may not be the only consent required.
Listed Building Consent may be necessary for works that affect the special architectural or historic interest of a listed building. This can include alterations, extensions, demolition and certain internal or external works.
What Works May Require Listed Building Consent?
Depending on the building and the proposed works, consent may be required for:
- Extensions
- Alterations to the external appearance
- Removal or alteration of historic features
- Changes to windows and doors
- Roof alterations
- Internal alterations
- Demolition
- Structural changes
The requirement for consent depends on the specific works and their effect on the listed building.
Carrying out works to a listed building without the necessary consent can have serious legal and planning consequences.
Heritage Planning for Extensions and Alterations
Extending or altering a historic property requires careful consideration of its existing architectural character.
A poorly designed extension can negatively affect the significance of a heritage asset, whereas a well-designed proposal can provide modern functionality while respecting the property’s historic character.
Designing an Extension to a Historic Building
Important considerations may include:
- The scale and proportions of the extension
- The relationship between old and new elements
- Materials and finishes
- Roof design
- Window and door details
- Views towards and from the heritage asset
- The impact on historic features
- The contribution of the surrounding landscape
A heritage planning consultant can work with the design team to identify potential heritage issues at an early stage.
Heritage Assets and Their Settings
Heritage planning does not only consider the physical structure of a historic building. The setting of a heritage asset can also be important.
The setting may include the surrounding buildings, landscape, streetscape, views and other features that contribute to the asset’s significance.
A new development does not necessarily need to be immediately next to a heritage asset to affect its setting.
Assessing Impact on Heritage Assets
The potential impact of a proposal may depend on factors such as:
- The scale of the development
- Its height and massing
- Its position
- Materials and appearance
- Changes to important views
- Changes to the historic landscape
- The relationship between the proposal and the heritage asset
Understanding these factors early can help inform the design and planning strategy.
Heritage Planning and Planning Applications
Heritage considerations should ideally be incorporated into a planning proposal before the application is submitted.
Where relevant, the application may need to include supporting heritage documentation such as a Heritage Statement or Heritage Impact Assessment.
Pre-Application Heritage Advice
Obtaining advice before submitting a planning application can help identify potential problems at an early stage.
Pre-application discussions with the local planning authority may help establish:
- Which heritage assets could be affected
- What information will be required
- Potential heritage concerns
- Appropriate design approaches
- Possible mitigation measures
- Whether Listed Building Consent or other approvals may be required
Early advice can reduce the risk of significant changes being required later in the planning process.
Heritage Planning and Development in Conservation Areas
Development within a conservation area should take account of the area’s special character and appearance.
This does not mean that development is prohibited. Instead, proposals should be carefully designed to respond to the historic environment.
A heritage planning consultant can help assess the existing character of the area and advise on an appropriate development strategy.
New Development in Historic Areas
New development may be acceptable within a historic area where it responds appropriately to its context.
Factors such as scale, materials, layout, height and architectural design can all influence whether a proposal integrates successfully into its surroundings.
Why Use a Heritage Planning Consultant?

Heritage Planning Consultant UK: Frequently Asked Questions
What is a heritage planning consultant?
A heritage planning consultant provides specialist advice on planning proposals that could affect historic buildings, conservation areas, listed buildings or other heritage assets.
Do I need a heritage planning consultant for a listed building?
Not every listed building project requires a heritage planning consultant. However, specialist advice can be valuable where you are proposing alterations, extensions, changes of use or other works that could affect the building’s special architectural or historic interest.
What is a Heritage Statement?
A Heritage Statement is a document that explains the significance of relevant heritage assets and assesses how a proposed development may affect them. It can be required as supporting information for certain planning applications.
What is a Heritage Impact Assessment?
A Heritage Impact Assessment considers the potential effects of a proposed development on the significance of a heritage asset and, where appropriate, its setting. It can help demonstrate how potential harm has been identified and addressed.
Do I need planning permission and Listed Building Consent?
Potentially. Planning permission and Listed Building Consent are separate forms of consent. Depending on the proposed works, you may need one or both.
Can I extend a listed building?
It may be possible to extend a listed building, but the proposal will need to carefully consider the building’s special architectural and historic interest. Planning permission and Listed Building Consent may be required.
Can I alter the interior of a listed building?
Internal alterations can require Listed Building Consent if they affect the special architectural or historic interest of the building. You should establish whether consent is required before carrying out works.
Can I develop land near a listed building?
Development near a listed building may be possible, but the impact on the listed building and its setting may need to be considered as part of the planning process.
Does development in a conservation area require planning permission?
Being located within a conservation area does not automatically mean that every form of development requires planning permission. However, some Permitted Development rights may be restricted, and additional planning considerations can apply.
What happens if I carry out unauthorised works to a listed building?
Unauthorised works to a listed building can have serious consequences. Listed Building Consent should be obtained where required before works begin. If unauthorised works have already been carried out, specialist planning and legal advice should be sought.
