What Is a HELAA?
HELAA stands for: Housing and Economic Land Availability Assessment
It is a document prepared by local planning authorities to identify and assess land that may be capable of accommodating future housing, employment or mixed-use development. The purpose of the assessment is to help councils understand whether sufficient land is available to meet future development needs over the plan period.
A HELAA is primarily an evidence-gathering exercise. Local authorities use it to review land submitted by landowners, developers and promoters, alongside other sites identified through their own research. Each site is assessed against a range of factors, including suitability, availability and achievability, to determine whether it may have potential for future development.
Importantly, a HELAA does not allocate land for development and does not grant planning permission. Instead, it forms part of the evidence base used to inform Local Plan preparation and future growth strategies. Nevertheless, inclusion within a HELAA can be significant because it demonstrates that a site has been recognised and assessed by the local planning authority as a potential development opportunity. For many landowners, it can represent an important early step in the process of unlocking future development potential and enhancing land value.
What Is a SHLAA?
SHLAA stands for: Strategic Housing Land Availability Assessment
SHLAAs were widely used by local planning authorities before the introduction of HELAAs and were primarily focused on identifying land that may be capable of accommodating future housing development. The purpose of the assessment was to help councils understand whether sufficient land was available to meet projected housing needs over the plan period.
Whilst planning terminology has evolved, SHLAAs and HELAAs perform a broadly similar role. Both are evidence-based assessments used to identify and evaluate potential development sites, although HELAAs generally have a wider scope because they consider both housing and employment land opportunities. In many areas, older SHLAA documents remain relevant and may still provide useful insight into how a site has previously been assessed by the local authority.
Importantly, inclusion within a SHLAA does not allocate land for development and does not grant planning permission. However, it can indicate that a site has been recognised by the council as having potential for future development and may therefore represent an important step in the planning process. For landowners, SHLAA inclusion can often provide valuable evidence of development potential and may increase interest from developers, promoters and investors seeking future opportunities.
Why Are These Assessments Important?
HELAA and SHLAA assessments often represent the first stage of a site's journey through the planning system. They help local planning authorities identify potential development opportunities and understand whether sufficient land exists to meet future housing and employment needs. By assessing land availability across their area, councils can build an evidence base that informs Local Plan preparation, growth strategies and future site allocations.
For landowners, inclusion within a HELAA or SHLAA can be particularly important because it demonstrates that a site has been identified and assessed by the local authority as a potential development opportunity. Whilst inclusion does not guarantee allocation or planning permission, it can increase a site's visibility within the planning process and help establish its credentials for future consideration.
These assessments also provide valuable insight into how a council views a site's suitability, availability and achievability. As a result, they can often serve as an important indicator of future development potential and may influence the level of interest shown by developers, promoters and investors. For many sites, inclusion within a HELAA or SHLAA is one of the earliest steps towards unlocking long-term development value.
They help councils identify:
Potential Housing Sites
One of the primary purposes of a HELAA or SHLAA is to help local planning authorities identify land that may be capable of accommodating future housing development. Councils assess submitted sites and other potential opportunities to determine whether they could contribute towards meeting future housing requirements over the plan period. This process helps authorities understand where growth may be delivered and whether sufficient land exists to support future housing needs. Whilst inclusion within a HELAA or SHLAA does not guarantee development, it can indicate that a site has been recognised as having potential to contribute towards future housing delivery.
Employment Land
HELAA assessments also help local planning authorities identify opportunities for employment, commercial and mixed-use development that can support future economic growth. As well as assessing land for housing, councils must ensure that sufficient land is available to accommodate businesses, create jobs and support investment within their area. This may include sites suitable for offices, industrial development, warehousing, logistics, commercial premises and mixed-use schemes. By identifying potential employment land opportunities at an early stage, authorities can better plan for future economic needs and ensure that growth is supported by an appropriate supply of development land throughout the plan period.
Strategic Growth Areas
HELAA and SHLAA assessments can also help identify locations that may be suitable for strategic growth over the longer term. These are often areas where future housing, employment development and infrastructure investment can be accommodated in a coordinated and sustainable manner. By assessing a wide range of sites, local planning authorities can identify opportunities that align with broader growth strategies, infrastructure improvements and regional development objectives. Sites located within or adjacent to emerging strategic growth areas may attract increased attention from councils, developers and investors because they have the potential to contribute towards significant long-term housing and economic growth.
Future Allocation Candidates
HELAA and SHLAA assessments play an important role in identifying sites that may have the potential to be allocated for development through emerging Local Plans and future planning policy reviews. By assessing land against factors such as suitability, availability and achievability, local planning authorities can determine which sites may be capable of contributing towards future housing and employment needs. Whilst inclusion within a HELAA or SHLAA does not guarantee allocation, it can indicate that a site has been recognised as a potential development opportunity and may warrant further consideration as the Local Plan progresses. For many landowners, being identified as a future allocation candidate can represent an important step towards enhancing development prospects and unlocking long-term land value.
What Does Inclusion Mean?
If your land appears within a HELAA or SHLAA, it generally means that the local planning authority has reviewed the site and assessed its potential for future development. The assessment will usually consider factors such as suitability, availability and achievability, together with a range of planning, environmental and technical considerations.
Inclusion within a HELAA or SHLAA is often a positive indicator because it demonstrates that the site has been identified and recognised by the council as a potential development opportunity. However, it is important to understand that inclusion does not mean the land has been allocated for development, nor does it guarantee that planning permission will be granted in the future.
Instead, HELAA and SHLAA documents form part of the authority's evidence base and help inform Local Plan preparation and future growth strategies. For landowners, inclusion can be significant because it raises the profile of a site within the planning process and may increase interest from developers, promoters and investors. In many cases, it represents an important early step towards unlocking future development potential and enhancing long-term land value.
Assessment criteria commonly includes:
Inclusion can be a positive indicator, although it should not be confused with planning permission.
Can Inclusion Increase Land Value?
Potentially. Whilst inclusion within a HELAA or SHLAA does not guarantee planning permission or allocation, it can increase market interest in a site. Developers, investors and land promoters frequently review HELAA and SHLAA documents when identifying potential development opportunities because these assessments provide an indication of how a local planning authority has viewed a site's development prospects.
Where a site has been assessed positively, inclusion can help demonstrate that the land has been recognised as a potential development opportunity and may warrant further consideration through the Local Plan process. This can make the site more attractive to parties seeking strategic land opportunities and, in some cases, may lead to increased competition and enhanced value compared with land that has not been identified within the council's evidence base.
The extent of any value increase will depend on the specific findings of the assessment, the site's planning prospects and wider market conditions. However, for many landowners, inclusion within a HELAA or SHLAA can represent an important milestone that raises the profile of the land and helps support its long-term development potential.
Sites recognised within these assessments may attract greater interest, particularly where:
- Housing demand is strong
- Local Plan reviews are underway
- The site adjoins existing settlements
- The council faces housing shortages
What Happens Next?
Following assessment, a council may:
- Continue evaluating the site
- Request additional information
- Include the site within future consultations
- Allocate the land within a Local Plan
- Reject the site
Allocation generally represents the most significant milestone.
Can Landowners Submit Sites?
Yes, landowners can usually put sites forward through:
Whilst landowners can submit sites themselves, a professionally prepared submission will often carry significantly more weight. A specialist land promotion company such as Value My Land can assess the planning merits of a site, identify potential constraints, prepare robust supporting evidence, and present a clear planning case aligned with local and national planning policy. This helps ensure that the site is promoted in the most effective way possible, maximising its chances of being recognised as a suitable development opportunity during the Local Plan process.
Timing is often critical. Missing an opportunity to submit land can delay consideration for years.
