Evidence base


Brownfield land register

The Town & Country Planning (Brownfield Land Register) Regulations 2017, which came into effect on 16 April 2017, requires local authorities to prepare, maintain and publish a register specifically of previously developed land.

The Brownfield land register is made up of two parts:

  • Part 1 contains a list of brownfield sites which are considered to be suitable for housing
  • Part 2 identifies brownfield sites that have been granted planning permission-in-principle (PiP) for residential development

We've not started work on Part 2 of this register at the current time.

The register identifies previously developed land (PDL) in the borough that we've assessed as being appropriate (suitable, available and achievable) for housing development.  It comprises a standard set of information to help developers identify suitable sites for housing development, speeding up the construction of new homes and maximising the number of homes built on brownfield sites. The register [xls] has been prepared in accordance with national guidelines regarding the range of site-specific information.

The information to be included in the register is set out in schedule 2 of the regulations. The eligibility criteria for sites to be included on the Brownfield Register is that they must meet the definition of ‘previously developed land’ in the National Planning Policy Framework and be either at least 0.25 hectares in size or capable of providing 5 or more dwellings.  Sites that are part or mixed brownfield land can be included in the Brownfield Register.  Furthermore the sites must be suitable, available and achievable in line with the meaning in Paragraph 2 of regulation 4 of the Regulations.

In order to align with the annual housing monitoring survey, the Brownfield land register uses information contained in our Strategic Housing Land Availability Assessment (SHLAA). The Register includes:

  • PDL sites in the Strategic Housing Land Availability Assessment (SHLAA) that have been assessed to be suitable, available and achievable
  • Small PDL sites less than 0.25 hectares that have an estimated or approved capacity of 5 or more dwellings

It's important to note that the Brownfield Register sites that do not have planning permission have an indicative dwelling capacity attributed to them.  This indicative capacity is not a site allocation but an estimate based on the same assumptions as are used in the SHLAA for estimating site capacities and may not accord with any future planning permission granted on the site, which would be subject to more detailed assessment through the Development Management process.

We published our most recent Brownfield Land Register in July 2019 (using information from the 2018 SHLAA).  Therefore, the base date of the information is 31 March 2018 and includes sites that had commenced development at that date.

The Brownfield Register is available in the formats prescribed by the Government.  An additional Geographical Information System (GIS) layer is also available for download below as a shapefile.

Sites currently included in the Brownfield Register are also available to view using the link below (you will need to turn on the Brownfield Register in the legend on the left side of the map):

Next steps

The statutory Brownfield Register will be updated on an annual basis. The Brownfield Register will be a joint exercise with the SHLAA update.

We'll also be considering the potential to include sites in Part 2 of the Register which will grant permission in principle for housing led development.

Strategic Housing Land Availability Assessment (SHLAA)

The purpose of a Strategic Housing Land Availability Assessment (SHLAA) is to identify and evaluate the potential of land for future housing development, to ensure that the delivery targets in the Local Plan are continued to be met. 

The SHLAA is reviewed on an annual basis.  Each review presents an opportunity for additional sites to be considered and the methodology and approach to the assessment to be revisited.

Strategic Housing Land Availability Assessment (SHLAA) 2016 - Headline Findings

The headline findings from Warrington's housing Monitoring for 2016 can be found in the latest Annual Monitoring Report (2015/2016). The findings have been expanded to include the potential capacity of sites across the borough to accommodate new homes over the next 15 years, in addition to the borough’s 5 year housing land supply.

Whilst, it does not represent a comprehensive update of the SHLAA like what was undertaken in 2015 it provides an up to date position regarding the borough’s housing land supply position to give direction on the next stages necessary to ensure the housing elements of the Local Plan are revised in line with the High Court ruling and reinstated as soon as possible. Another comprehensive update of the SHLAA will be undertaken as part of the Local Plan Review.

As part of the Local Plan Review, Mickledore were commissioned to look at alternative forecasts for both housing and employment land which can be found below:

Publication of Strategic Housing Land Availability Assessment (SHLAA) 2015

Warrington Borough Council is progressing the work necessary to reinstate the Local Plan Housing target that was removed following a High Court judgement earlier in 2015.

The first stage of this work is the preparation of a Strategic Housing Land Availability Statement (SHLAA) to catalogue the potential capacity of sites across the borough to accommodate new homes over the next 15 years.

The SHLAA considers the suitability of all available and potential sites for housing. The Assessment looks at the likelihood of sites coming forward over time, their capacity for residential development and whether there are any constraints on them which would preclude housing from being developed.

The SHLAA is an information gathering exercise only. It forms part of the evidence base for the Local Plan. The inclusion of sites within the SHLAA does not imply that they will be allocated or receive planning consent for any form of development.

Following the consultation on the draft SHLAA in autumn 2015, the SHLAA has now been finalised for 2015. The report and associated maps and site schedules can be downloaded below:

Urban Capacity Statement 2016

The Council has commenced a review of its Local Plan Core Strategy following the High Court quashing the Local Plan’s housing target in February 2015.

As part of this review the Council has also undertaken detailed work to establish additional capacity to accommodate growth in the existing urban area and on green field sites outside of the Green Belt. This has confirmed a capacity for approximately 15,000 new homes.  The statement is available below:

Mid Mersey Strategic Housing Market Assessment (SHMA) 2016

The Council, in partnership with Halton and St Helens Councils, commissioned GL Hearn to prepare a Strategic Housing Market Assessment (SHMA). The SHMA identifies the Objectively Assessed Need for housing as well as considering the need for different types of housing and the housing needs of different groups within the community.

The final SHMA is available to download below:

An addendum to the published SHMA is available to download as part of the evidence base for the Local Plan Review.

Affordable Housing Viability Assessment

The aim of the Affordable Housing Viability Assessment is to examine and better understand the potential impact of revised affordable housing targets, thresholds and tenure splits on the viability of private housing developments within the borough.

Local Economic Assessment

The LEA is a factual assessment of the economic conditions of an area which will be used to inform the future strategies and policies of the Local Authority. All county councils and unitary councils are required to prepare such an assessment under the Local Democracy, Economic Development and Construction (LDEC) Act (2009).
