Heritage Impact Assessment (HIA) Services

Planning a development near a listed building, conservation area, or heritage site?
A Heritage Impact Assessment (HIA) is essential for ensuring that the historic character of the area is thoughtfully considered in your proposal. Most planning authorities require an HIA to assess how your project may impact the value and significance of nearby heritage assets.
Whether you’re undertaking a residential renovation, commercial construction, or infrastructure project, our HIA services support you by helping you:
Confidently navigate complex heritage and planning regulations
Minimize the risk of costly delays or planning refusals
Gain planning permission with a well-documented impact analysis
