Frequently Asked Questions

What does a heritage consultant do?

A heritage consultant provides expert advice on historic buildings and sites, particularly during the planning permission and listed building consent process. This includes preparing heritage statements, assessing the impact of proposed works, and supporting planning applications involving listed buildings or conservation areas. More information can be found on our heritage services page. 

Do I need to work with a heritage consultant?

The listed building consent and planning permission process can be complex, especially where heritage assets may be impacted. A professional heritage consultant works with homeowners, developers and architects to navigate this process. Our advice helps clients understand risks early and refine the proposed design to be heritage sensitive and well justified. Whilst planning decisions are made by the relevant local authority and outcomes cannot be guaranteed, involving a heritage consultant can improve the likelihood of achieving successful outcomes.

Do I need a heritage statement for my planning application?

You will usually need a heritage statement to support a planning application and/or listed building consent application if your project affects:

• A statutorily listed building (grade II, grade II* or grade I)
• A locally listed building (non-designated heritage asset)
• A property within a conservation area
• A site that is located close to any of the above

Local planning authorities require a heritage statement to assess how your proposal impacts the heritage assets in question.

What is listed building consent?

Listed building consent is a formal legal requirement for any works that affect the character or significance of a listed building. Listed building consent is separate from planning permission. In many cases, both may be required, and approval under one does not remove the need for the other.

When is listed building consent required?

Listed building consent is required for any works that would affect the character or special architectural or historic interest of a listed building. This can include external alterations, internal changes, extensions, and sometimes repairs, depending on their nature and extent.

Because listed buildings are protected in their entirety — inside and out — even works that may seem minor can require consent. This protection can also extend to structures within the curtilage of the listed building, such as outbuildings or boundary walls, even if they are not separately listed.

Consent may be needed for works such as altering windows or doors, removing or changing internal features, or making structural changes. As each building and proposal is different, requirements can vary and should be considered on a case-by-case basis.

Carrying out works without listed building consent is a criminal offence, so it is important to seek advice early and ensure the correct permissions are in place. A heritage consultant can help identify whether consent is likely to be required and guide the preparation of appropriate supporting information. Planning decisions are made by the relevant local authority.

Can you help with planning permission?

Yes, we support clients through the planning process by preparing the necessary heritage documentation and advising on how to improve the chances of approval.

How early should I involve a heritage consultant?

As early as possible. Engaging with us at the initial design stage can help avoid costly delays, redesigns, or refusals later in the planning process.

Do you work with homeowners or only developers?

We work with a range of clients, including homeowners, architects, planning consultants, and developers.

How much does a heritage statement cost?

Costs vary depending on the complexity and scale of the project. We provide clear, fixed-fee quotes once we understand your requirements.

How long does it take to prepare a heritage statement?

Typically, a heritage statement can take between 1–4 weeks, depending on the project scope and complexity, the extent of surveys and research required, and the availability of information.

What areas do you cover?

We work across the UK, with experience in a wide range of historic environments and with many local councils. Most of our projects are based in London, Sussex, Surrey and Hampshire, but do get in touch if your project is based further afield.

Can you advise before I purchase a property?

Yes — we can provide pre-purchase advice to help you understand any heritage constraints or risks before committing.

What information do you need to get started?

The more information you can provide, the better we will understand your project! Usually, we will ask for:

• Site address
• Description of proposed works
• Any existing plans,  drawings and photographs
