SHLAA and five-year housing land supply explained.

Two planning concepts often matter when buyers want to understand longer-term development pressure around a property.

What SHLAA can indicate

Strategic Housing Land Availability Assessment evidence can show whether land has been identified, promoted or assessed as potentially suitable for housing. It does not automatically mean planning permission will follow, but it can be a meaningful early-warning signal.

Why five-year land supply matters

Five-year housing land supply is a measure of whether a council can demonstrate enough deliverable housing land. A shortfall can change the planning balance and make some areas more susceptible to applications or allocations.

How this affects a buyer

A buyer may want to know whether nearby open land is merely undeveloped, or whether it has been promoted, assessed, allocated or affected by wider housing delivery pressure.

FAQ

Plain-English answers.

What is SHLAA?

SHLAA stands for Strategic Housing Land Availability Assessment. It is a planning evidence process used by councils to identify and assess land that may be capable of housing development.

Does a SHLAA site mean homes will definitely be built?

No. A SHLAA entry is not the same as planning permission, but it can be a useful signal that land has been identified, promoted or assessed for possible development.

Why does five-year land supply matter?

Where an authority cannot demonstrate sufficient housing land supply, the planning environment can become more sensitive and development pressure may increase.
