The historic elevations are still clearly distinct: the eastern building, 51-53 Charterhouse Street is grade II listed (listing entry and description at Appendix A); the western building, 47-49 Charterhouse Street, is not listed. The whole site lies within the Charterhouse Square Conservation Area, within the London Borough of Islington The buildings were converted into a power station c.1993. The current proposal comprises installation of heat pumps to internal spaces within the building, plant to the roof and pipe runs at various levels within the building. To facilitate installation of the heat pumps, the central door on the front elevation of 51-53 Charterhouse Street is proposed for temporary removal and re-installation. Methodology The aims of this statement are to identify the heritage assets affected by the proposals, evaluate their significance and assess the likely impact of the proposals upon them. Where harm may result from the proposed works, appropriate mitigation strategies are suggested. The heritage assets will comprise those directly affected within the site and those nearby which may have their settings changed. Effects to archaeological assets associated with the scheme are subject to a separate assessment. Significance is identified according to the guidance in Conservation Principles1. Impacts are described in terms of the extent to which the proposed development will degrade or enhance the assets’ significance. The report has been produced in accordance with appropriate historic environment guidance2. ____________________________________________________________________________________________________ 1 English Heritage, Conservation Principles, Policies and Guidance, 2008 Significance in Decision-Taking in the Historic Environment: Historic 2 Chartered Institute for Archaeologists 2017 Standard and Guidance for historic Environment Good Practice Advice in Planning Note 2 (aka GPA 2); Historic environment desk-based assessment; Historic England 2015 Managing England 2015 The Setting of Heritage Assets: Historic Environment Good LUC I 1 Chapter 1 Introduction EON Energy Centre, Charterhouse Street, London June 2020 Sources Sections 16 and 66, relating to applications for listed building consent and planning permission respectively, The following publicly accessible sources of state that, in considering applications affecting listed buildings, primary and secondary information were used in preparation “special regard” will be had “to the desirability of preserving of this report: the building or its setting or any features of special Information on designated heritage assets (National architectural or historic interest which it possesses.”; and, Heritage List for England); Section 72 which states that, in considering Cartographic sources – historic and modern Ordnance applications affecting conservation areas, “special attention Survey and other mapping at various scales; shall be paid to the desirability of preserving or enhancing the character or appearance of that area”.

As a minimum the relevant historic environment record should have been consulted and the heritage assets assessed using appropriate expertise where necessary. Where a site on which development is proposed includes, or has the potential to include, heritage assets with archaeological interest, local planning authorities should require developers to submit an appropriate desk-based assessment and, where necessary, a field evaluation. 190 Local planning authorities should identify and assess the particular significance of any heritage asset that may be affected by a proposal
