Protecting Britain’s built heritage

Yes. Unlike standard planning permission, Listed Building Consent covers all works affecting the character of a listed building — internal and external. There is a common misconception that Grade II listing only protects the exterior; this is incorrect. All features are protected regardless of whether they are specifically mentioned in the listing description. Removing a Victorian fireplace, altering original joinery, or changing internal layout all require consent.

A conservation area protects the character and appearance of an area as a whole — its streetscape, materials, scale, and spatial qualities. A listed building protects a specific structure. Conservation areas restrict permitted development rights and require permission for demolition and certain external changes; listed buildings require Listed Building Consent for any alteration affecting their character. Properties that are both face dual consent requirements.

Yes, with appropriate consents and design sensitivity. Historic England guidance encourages high-quality contemporary additions that are clearly of their time rather than pastiche reproductions. The key test is whether the addition preserves or enhances the significance of the heritage asset. Successful additions typically respect the scale, massing, and materials palette of the existing building while being honestly contemporary.

CDM 2015 applies equally, but the risk profile differs. Standard CDM practice emphasises risk elimination through design change — yet heritage buildings constrain design freedom because historic fabric must be preserved. Our Principal Designers develop CDM strategies that address construction risks through methodology and protection rather than fabric removal, using conservation-appropriate scaffolding, vibration controls, and specialist temporary works.

Discovery of unexpected historic fabric triggers a formal process. Work must stop in the affected area immediately, the discovery must be assessed by a heritage professional, and the local authority conservation officer — and potentially Historic England — notified. We maintain heritage discovery protocols on all projects, including pre-agreed notification procedures and programme contingencies, so unexpected finds are managed professionally.

Heritage construction requires demonstrably competent specialists — not just general contractors. Key trades include traditional lime workers, specialist joiners familiar with historic profiles, stone masons who can match existing masonry, heritage roofers experienced with lead, slate, or appropriate tile, and conservation-trained decorators. Using inappropriate contractors or materials is the single biggest cause of heritage enforcement action.

A Heritage Impact Assessment evaluates how proposed works will affect the significance of a heritage asset. It is required for any Listed Building Consent or planning application affecting a designated heritage asset. The HIA should describe the asset's significance, identify how proposals affect it, and justify any harm through demonstrable public benefit. Its quality directly influences the conservation officer's recommendation.

Yes, but it requires specialist knowledge. Standard measures — external wall insulation, replacement double glazing, cavity wall insulation — can cause serious damage through moisture trapping and loss of historic fabric. Heritage-appropriate approaches include secondary glazing, internal insulation with breathable materials, draught-proofing original windows, and appropriate heating upgrades. Historic England publishes detailed guidance on this.

The statutory determination period is 8 weeks (13 weeks for major applications). Heritage applications frequently take longer due to Historic England consultation for Grade I and II* buildings. Pre-application discussions add 4-8 weeks but significantly improve approval chances. For complex schemes, allow 4-6 months from first pre-application meeting to formal consent. We manage the entire consent timeline.

Several sources exist: the National Lottery Heritage Fund (grants from £10,000 to £5M+), Historic England repair grants for Heritage at Risk properties, listed building VAT zero-rating for qualifying alterations, and Section 106/CIL heritage allocations. Eligibility depends on your building's designation, condition, and the nature of proposed works. We advise on funding strategies and can coordinate grant applications alongside delivery.
