Local planning authorities have substantial statutory and non-statutory duties to provide specialist conservation advice, especially in delivering sustainable development and growth. This IHBC Guidance Note addresses key duties, threats, opportunities and solutions.
Duties in law and policy
Local planning authorities (LPAs) play the central and vital role in conserving England's heritage. Through planning, LPAs have statutory responsibility for decisions on how places change and how local heritage resources are conserved and developed. 
To deliver on an LPA's statutory duties, legislation also confirms that they need properly informed input of specialist conservation advice and judgement. For example the Planning (Listed Buildings and Conservation Areas) Act 1990 empowers the Secretary of State to approve 'the arrangements which the authority propose to make to obtain specialist advice in connection with their functions…'.
To deliver on an LPA's statutory duties, legislation also confirms that they need the properly informed input of specialist conservation advice and judgement. For example, the Planning (Listed Buildings and Conservation Areas) Act 1990 empowers the Secretary of State to approve 'the arrangements which the authority propose to make to obtain specialist advice in connection with their functions…'. 
England's National Planning Policy Framework (NPPF) also confirms the importance of appropriate and targeted specialist input as part of the LPA's duties to conservation across the entire built and historic environment. Through the NPPF planning authorities have specific corporate duties to make informed planning decisions on how 'special interest' (NPPF 127) and 'significance' (NPPF 17; 126 etc.) are managed as all of their places develop, following the statutory duties cited above.
With a 'Core Planning' principle of the NPPF being to: 'conserve heritage assets in a manner appropriate to their significance' (NPPF 17), it also highlights areas where specific conservation skills are essential to informed decisions. These include determining proportionality in heritage values (NPPF 128) and evidence (NPPF 129); assessing 'substantial' harm and mitigation to heritage works (for example, NPPF 132; 133, 134, 141), and character in new design in the historic environment (NPPF 58, 80, 126), among others.
Through Building Regulations specialist conservation advice is needed also to help LPAs meet climate change challenges in traditional buildings  and advise on the interpretation of the Secure and Sustainable Buildings Act 2004. 
Threats to economic and environmental planning
Statute and policy recognise that if a local authority does not have access to skilled advice at the right level, or its advisory process is not functioning, then decisions cannot be properly informed. This threatens the built and historic environment by putting resources and assets at risk. It also undermines confidence in the competence of the authority. Decisions also are more open to ombudsmen's review and challenge in the courts. The 2010'Penfold review of non-planning consents' highlighted how failings here slowed planning processes, development and growth.
Extensive research confirms that effective conservation services play a positive role in local enhancement and regeneration, generating inward investment, sustainable jobs and growth.  Clearly such conservation services are not only a legal and operational duty, but they offer affordable and invaluable ways to underpin local jobs and growth.
The best way for LPAs to address statutory and corporate duties to conservation is to have an appropriate level of informed professional conservation advice accessible across its planning service. A simple way to demonstrate a commitment to those duties is to employ suitably qualified conservation specialists such as Conservation Officers. Penfold particularly recommended the skills sets of IHBC members. 
Recommendation on publicising conservation resources
The IHBC strongly encourages all planning authorities to specify how they are addressing their statutory and corporate duties to conservation. A prominent and accessible description of the resources allocated and processes adopted may be a simple and economic service improvement. Such practice also aligns with the recommendations of Penfold.
