Social Infrastructure Assessment
A Social Infrastructure Assessment evaluates whether existing community facilities and services have sufficient capacity to serve the additional population generated by a proposed development, or whether new or expanded provision is needed. With GP surgeries, schools, and community facilities under increasing pressure across the UK, local authorities are placing growing emphasis on ensuring that new development does not exacerbate existing shortfalls in social infrastructure.

What is a Social Infrastructure Assessment?
A Social Infrastructure Assessment (SIA) is a planning document that analyses the capacity and accessibility of community services and facilities in the vicinity of a development site, assesses the additional demand that the proposed development will place on those services, and identifies the new or improved infrastructure needed to maintain acceptable levels of provision. Social infrastructure encompasses a wide range of facilities including primary and secondary schools, GP surgeries and health centres, dentists and pharmacies, community halls and meeting spaces, libraries, places of worship, sports and leisure centres, children's centres and nurseries, and emergency services facilities.
When is a Social Infrastructure Assessment required?
Social Infrastructure Assessments are increasingly required for major residential developments, typically those of 50 units or more, although some councils set lower thresholds. The requirement is particularly common in London, where the London Plan and individual borough plans include specific social infrastructure policies. Outside London, many councils address social infrastructure through their planning obligations policies and CIL charging schedules. The NPPF at paragraph 97 states that planning decisions should guard against the unnecessary loss of valued community facilities and services, and should ensure that established shops, facilities, and services can develop and modernise in a way that is sustainable.
What does a Social Infrastructure Assessment include?
A thorough Social Infrastructure Assessment includes an estimate of the population generated by the development by age group and household type, an audit of existing social infrastructure within appropriate catchment distances, an assessment of current capacity utilisation at each facility, a demand analysis calculating the additional need arising from the development population, identification of capacity shortfalls where demand exceeds available capacity, recommendations for new or expanded facilities to address the shortfalls, cost estimates for required infrastructure and proposed funding mechanisms, and a phasing strategy aligning infrastructure delivery with housing completions. The assessment should draw on data from service providers including the local Clinical Commissioning Group (or Integrated Care Board), the local education authority, and community services.
How much does a Social Infrastructure Assessment cost?
A Social Infrastructure Assessment for a mid-sized residential development typically costs between £3,000 and £8,000. Large-scale schemes requiring engagement with multiple service providers, detailed capacity modelling, and infrastructure cost planning can cost £10,000 to £20,000. Assessments for strategic sites or urban extensions that require masterplanning of new community facilities are at the higher end of this range.
Who can prepare a Social Infrastructure Assessment?
Social Infrastructure Assessments are prepared by planning consultants, social researchers, or specialist infrastructure planning consultancies. The author should have experience in engaging with public service providers and understanding their capacity planning frameworks. Familiarity with NHS premises standards, Department for Education school place planning methodology, and local authority community facility strategies is essential. RTPI-qualified planners with social infrastructure experience are well-placed to prepare these assessments.
How long does a Social Infrastructure Assessment take?
A Social Infrastructure Assessment typically takes 4 to 8 weeks to prepare, with the main variable being the response times of service providers to capacity enquiries. NHS bodies, education authorities, and other providers may take several weeks to provide data on current capacity and expansion plans. Allowing sufficient time for these enquiries and building in follow-up discussions is essential for producing an accurate and credible assessment.
Frequently Asked Questions
What is the difference between social infrastructure and community infrastructure?
The terms are often used interchangeably, though social infrastructure tends to have a broader scope. Social infrastructure encompasses all the facilities and services that support community life, including health, education, emergency services, culture, sport, and community meeting places. Community infrastructure sometimes refers more narrowly to community halls, libraries, and cultural facilities. Your assessment should cover whatever scope the local plan policy defines.
How is GP surgery capacity assessed?
GP surgery capacity is assessed by identifying all practices within a reasonable travel distance of the development, typically 1 to 2 kilometres, and comparing their current patient lists with their maximum patient capacity. The Integrated Care Board or local commissioners can provide data on list sizes and capacity. Where practices are already operating at or near capacity, the additional patients from the development will require either practice expansion or a new health facility.
How are school place requirements calculated?
School place requirements are calculated using child yield multipliers applied to the dwelling mix of the proposed development. The local education authority maintains data on school place availability and can confirm existing surplus or deficit in the area. Standard multipliers vary, but a typical approach uses Department for Education pupil yield data or the council's own school place planning ratios. The assessment should cover primary, secondary, and early years provision.
Can Section 106 contributions fund social infrastructure?
Yes. Section 106 contributions are one of the primary mechanisms for funding social infrastructure generated by development. Contributions can be directed to specific projects such as GP surgery expansions, new classroom provision, or community hall construction. Where a council operates a Community Infrastructure Levy, some social infrastructure may be funded through CIL instead, but site-specific mitigation often requires bespoke Section 106 obligations.
What happens if there is no GP capacity in the area?
If existing GP practices cannot accommodate additional patients, the assessment should explore options including expansion of existing premises, relocation of a practice to larger premises, provision of a new health facility within the development, or financial contributions towards NHS capital projects. The Integrated Care Board should be involved in determining the most appropriate solution and may have existing plans for capacity improvements in the area.
How does CIL interact with social infrastructure planning?
The Community Infrastructure Levy is intended to fund the infrastructure needed to support growth across the local authority area, including schools, health facilities, and community spaces. Where CIL is in place, councils may rely on CIL receipts to fund some social infrastructure rather than seeking site-specific Section 106 contributions. However, Regulation 122 of the CIL Regulations allows site-specific Section 106 obligations where they are necessary, directly related to the development, and fairly and reasonably related in scale.
Should the assessment cover faith facilities?
Places of worship and faith community facilities are a legitimate category of social infrastructure. While planning authorities cannot require developers to fund religious buildings, the assessment should acknowledge the needs of faith communities within the population and consider whether existing faith facilities can accommodate additional worshippers. For large developments creating new communities, providing flexible multi-faith or community spaces that can be used for worship is sometimes proposed.
How far should social infrastructure be from homes?
Accessibility standards vary by facility type. Fields in Trust and various planning guidance suggest that primary schools should be within 600 to 800 metres walking distance, GP surgeries within 800 metres to 1 kilometre, community halls within 600 metres, and local shops within 400 to 800 metres. These distances ensure that facilities are accessible on foot and by public transport, supporting sustainable travel patterns and social inclusion.
What is an infrastructure delivery plan?
An Infrastructure Delivery Plan (IDP) is a document, usually prepared by the local authority, that identifies all the infrastructure needed to support the growth set out in the local plan. It covers physical, social, and green infrastructure, identifies responsible delivery bodies, estimates costs, and sets out funding sources. Your Social Infrastructure Assessment should align with the council's IDP and identify how the development contributes to or draws upon the planned infrastructure.
Can loss of social infrastructure facilities be resisted through planning?
Yes. The NPPF at paragraph 97 guards against the unnecessary loss of valued community facilities and services. Many local plans include policies that resist the loss of community facilities unless it can be demonstrated that the facility is no longer needed, that adequate alternative provision exists, or that the facility is no longer viable. Loss of social infrastructure without adequate justification is a common reason for planning refusal.
