Historic buildings can offer distinctive spaces for homes, businesses and community uses. Yet bringing an older property into modern use may involve more than repairing its fabric or updating its layout. Owners may need to balance practical needs—such as improved accessibility, energy efficiency, additional space or a change of use—with the features that give the building its heritage value.
A heritage planning consultant can help navigate this balance. Rather than treating conservation and development as opposing objectives, the process involves understanding what makes a building significant and assessing how proposed changes could affect that significance.
For property owners, developers and investors, this early work can help avoid designs that are difficult to approve, costly alterations after submission or interventions that damage important historic features.
Why Understanding a Building’s Significance Comes First
Before designing alterations to a historic property, it is important to establish what is significant about it. This may include its architectural design, construction materials, craftsmanship, historic associations, interior features or contribution to the surrounding area.
The significance of a heritage asset is not always limited to its most obvious or decorative elements. Historic England advises that proposals should be informed by an understanding of the asset and the impact of the proposed works. The level of assessment should be proportionate to the significance of the asset and the nature of the intervention.A heritage planning consultant may help the project team identify:
- Features that contribute to the building’s historic or architectural interest.
- Later alterations that may themselves have significance.
- Areas where change could be less harmful.
- The effect of proposed works on the building’s setting.
- Information that may be required to explain and justify the design.
This assessment can influence the project before detailed drawings and specifications are finalised.
Making Historic Buildings Work for Modern Needs
A building’s continued use can support its long-term care. However, new requirements often involve changes that need careful consideration.
Improving Energy Efficiency
Owners may wish to reduce heat loss, improve comfort or lower energy consumption. Potential measures include upgrading windows, improving insulation or introducing modern heating systems.
The most appropriate solution depends on the building’s construction and heritage significance. Replacing historic windows, for example, may affect its character and could require consent. Historic England recommends assessing the form, materials, history and significance of windows before deciding how to modify them.
A heritage-led approach considers whether performance improvements can be achieved through less harmful measures, such as draught-proofing, secondary glazing or carefully designed upgrades—where suitable for the individual building.
Creating Additional Space
Extensions, internal reconfiguration and new services can help a historic property meet contemporary needs. But a design that works well for a modern building may be unsuitable for a heritage asset.
The assessment may consider the scale, location, materials and visibility of an addition, as well as whether it affects significant historic fabric. In some cases, placing new accommodation in a less sensitive part of the site or using a clearly differentiated design may help reduce harm.
There is no universal design solution. Each proposal must be considered in the context of the building and the significance of the features affected.
Changing the Building’s Use
Historic properties may be considered for conversion into homes, offices, hospitality premises, studios or community facilities. A change of use can help secure a building’s future, but it may also require alterations to entrances, circulation, fire safety arrangements, services or internal layouts.
The planning assessment should consider both the proposed use and the physical changes needed to support it. Depending on the property and the nature of the works, planning permission and listed building consent may be required.
A consultant can help identify the relevant consent route and the heritage issues that need to be addressed before the project proceeds.
Listed Building Consent and Planning Permission
Listed building consent and planning permission are separate forms of control, although a proposal may require both.
In England, listed building consent is generally required for works involving the alteration, extension or demolition of a listed building where the works affect its character as a building of special architectural or historic interest. The need for consent depends on the nature and effect of the specific works. Carrying out works requiring listed building consent without obtaining it can have serious legal consequences
Planning permission may also be required, for example, for development involving an extension or a change of use. A property’s listed status does not automatically mean every proposed activity requires the same consent, so the position should be checked carefully.
A heritage planning consultant can help establish:
- Whether the building is listed or lies within a conservation area.
- Which parts of the property or site may be protected.
- Whether the proposed works require listed building consent, planning permission or other approvals.
- What drawings, heritage assessments or supporting statements may be needed.
- Whether early discussions with the local planning authority would be beneficial.
Historic England’s guidance emphasises the value of understanding the building’s special interest before preparing an application.
Avoiding Expensive Design Changes and Delays
Heritage constraints can affect project costs when they are discovered late. A design may need to be revised if it removes significant features, introduces an unsuitable addition or fails to explain the effect of the proposed works.
A heritage planning consultant can contribute to risk management by reviewing the proposal at an early stage.
Reviewing the Proposal Before Detailed Design
An initial heritage review can identify sensitive features and areas where alterations may be more difficult to justify. This allows architects, engineers and other specialists to develop their designs with those constraints in mind.
Preparing a Clear Heritage Case
Applications affecting heritage assets often need to explain the significance of the building and how the proposal would affect it. The supporting information should be relevant and proportionate to the nature of the works.
A heritage statement may describe the building’s history, important features, the proposed intervention and the reasoning behind the design. It can also explain how alternative approaches were considered.
Coordinating with Other Professionals
Heritage projects may involve architects, conservation specialists, structural engineers, building surveyors and contractors experienced in traditional materials.
Coordinating advice can help ensure that the planning approach reflects the practical requirements of the building, rather than producing a design that is attractive on paper but difficult to implement sensitively.
What a Heritage Planning Consultant Can Do
The scope of a consultant’s work depends on the property and the client’s objectives. Services may include:
- Heritage appraisal: identifying the property’s significance and potential planning sensitivities.
- Consent strategy: assessing which permissions or approvals may be needed.
- Design review: considering the heritage implications of proposed alterations, extensions or conversion.
- Heritage statements: preparing or coordinating supporting information for applications.
- Planning application support: assisting with submissions and responses to planning authority queries.
- Appeal advice: reviewing a refusal and considering whether an appeal or revised proposal may be appropriate.
The consultant’s role is to help the project team understand the planning and heritage issues. Specialist technical design, conservation repairs or legal advice may need to be provided by other appropriately qualified professionals.
When to Seek Heritage Planning Advice
It is sensible to seek advice before committing to a design or starting work if you are:
- Buying a listed building with the intention of renovating or converting it.
- Planning an extension or internal alterations to a historic property.
- Considering replacement windows, new services or energy-efficiency upgrades.
- Proposing a new use that may require physical changes.
- Developing land near a heritage asset where its setting may be affected.
- Unsure whether proposed works require listed building consent.
- Responding to concerns raised by a planning or conservation officer.
Early advice can help clarify what is feasible, which elements require particular care and what information should be prepared before an application is submitted.

Frequently Asked Questions
What does a heritage planning consultant do?
A heritage planning consultant helps assess how proposed development or alterations may affect a historic building or place. They may advise on significance, planning constraints, consent requirements, heritage statements and application strategy.
Do all works to a listed building require listed building consent?
No. Whether consent is required depends on the nature of the works and whether they affect the building’s special architectural or historic character. Owners should check the position before starting work, as unauthorised works can have serious consequences.
Is listed building consent the same as planning permission?
No. They are distinct controls. Some projects require both, while others may require only one or may not require either. The applicable requirements depend on the proposed works, the property and relevant planning controls.
Can a listed building be converted to a different use?
Potentially, yes. The proposed use must be assessed against relevant planning policies and any necessary permissions. The physical alterations required for the conversion may also need listed building consent if they affect the building’s special character.
Can energy-efficiency improvements be made to a historic building?
Often, but the appropriate measures depend on the building’s construction and significance. Some interventions may affect historic fabric or appearance, so it is important to assess the proposed changes and relevant consent requirements before proceeding.
What should a heritage statement include?
A heritage statement typically explains the significance of the affected heritage asset, describes the proposed works and assesses their likely impact. Its level of detail should be proportionate to the significance of the asset and the nature of the proposal.
Conclusion
A heritage planning consultant can help owners and developers approach historic buildings as usable, adaptable assets while respecting their special interest. The key is to understand the building before deciding how to change it.
