Abandonment of use: when a lawful planning use is lost

 

A use of land can be perfectly lawful and still be lost. That is what planning lawyers mean by abandonment of use.

It usually becomes important when a house has stood empty for years, an old commercial or industrial use has stopped, a yard has fallen into disuse, or somebody wants to rely on a historic use as a fallback position. The question is not simply whether the use has stopped. The real question is whether, looking objectively at everything that has happened, the former lawful use has been abandoned rather than merely suspended or left dormant.

There is no fixed period after which abandonment automatically occurs. A use does not disappear simply because nothing has happened for ten, twenty or even thirty years. Equally, an owner cannot keep a use alive forever merely by saying, “I always intended to use it again”. The courts look at the facts on the ground.

This page explains the four-factor test used by the courts, the difference between abandonment and dormancy, why a planning permission is different from a lawful use, and how to prove the position if a council disagrees.

 

What does abandonment mean in planning?

 

Abandonment is a common-law planning principle. A lawful use which has genuinely been abandoned loses its protection. If there is no other lawful use to fall back on, starting that use again may amount to a fresh material change of use requiring planning permission.

The principle was established in cases including Hartley v Minister of Housing and Local Government [1970] 1 QB 413 and developed through Trustees of the Castell-y-Mynach Estate v Secretary of State for Wales [1985] JPL 40 and Hughes v Secretary of State for the Environment, Transport and the Regions [2000] EWCA Civ 506; (2000) 80 P&CR 397.

The modern practical test is objective. The question is what a reasonable person, knowing all the relevant circumstances, would conclude about the former use. That means the owner’s intention matters, but it is only part of the picture.

 

How is abandonment of use decided?

 

The courts normally consider four factors together:

• the physical condition of the land or building
• the period for which the former use has not been carried on
• whether another use has intervened
• the owner’s intentions concerning the former use

No single factor automatically decides the case. Their weight depends on the facts.

Hughes is particularly useful because the Court of Appeal confirmed that the exercise is objective. A landowner may genuinely say that they always hoped to resume the former use, but the decision-maker can still find abandonment if the condition of the site, the passage of time and the surrounding circumstances point strongly the other way.

 

1. The physical condition of the land or building

 

Physical condition can be powerful evidence. A building which remains capable of its former use is in a very different position from one which has become a roofless shell, has been stripped of essential equipment or has been altered so substantially that the old activity could no longer realistically operate there.

That does not mean disrepair equals abandonment. A neglected building can still retain a lawful use. The question is what the condition says about the continuing reality of that use when considered with everything else.

In Hughes, a bungalow had been unoccupied for decades and had fallen into a very poor state. The first-instance High Court decision in 1999 had quashed the Inspector’s decision, but the Court of Appeal reversed that approach on 19 January 2000 and held that the Inspector was entitled to find the residential use abandoned even though there was evidence that successive owners had contemplated residential use in the future.

Britannia Assets (UK) Ltd v Secretary of State for Communities and Local Government [2011] EWHC 1908 (Admin) gives a more industrial example. Storage tanks and pipework associated with a petroleum-storage use had been dismantled and removed, and other works were inconsistent with that use. The High Court upheld the conclusion that the lawful petroleum-storage use had been abandoned.

 

2. How long has the use stopped?

 

There is no statutory abandonment period. Ten years of inactivity does not automatically destroy a use and four years does not automatically preserve one. The familiar enforcement time limits deal with a different question.

Lengthy non-use is evidence, and the longer it continues the more important the surrounding explanation becomes. But time must be considered with the physical condition, any intervening use and the owner’s objectively demonstrated intentions.

This is why old houses and commercial premises can produce difficult cases. A building may have been empty for decades yet still retain its use on one set of facts, while a shorter period combined with demolition, removal of essential infrastructure or a clear alternative use may support abandonment.

 

3. Has another use taken over?

 

An intervening use can be highly significant. Sometimes it will simply be evidence pointing towards abandonment. In other cases the later use may itself amount to a material change of use which has superseded the earlier planning use.

That is one reason why it is dangerous to talk about an old use as though it remains permanently stored in the planning history. A site may have a long and complicated sequence of lawful and unlawful uses. You need to identify the relevant planning unit, what use was lawful, what happened afterwards and whether the later events legally displaced or abandoned the earlier position.

A separate statutory rule can sometimes restore an earlier lawful use after enforcement. Section 57(4) of the Town and Country Planning Act 1990 is covered on our page about reverting to a previous lawful use after an enforcement notice. That is a different mechanism from common-law abandonment and the two should not be confused.

 

4. What did the owner intend?

 

Intention matters, but planning law does not simply ask what was inside the owner’s head. The test is objective.

Useful evidence might include attempts to market or let the property for the former use, maintenance and repair, applications intended to preserve or facilitate that use, business records, retained equipment, professional reports, correspondence and concrete steps towards recommencement.

By contrast, a bare statement made years later that the owner “never intended to abandon it” may carry limited weight if the physical evidence points in the opposite direction.

The Court of Appeal in Hughes made this especially clear. The owner’s intention is relevant, but it is not decisive. The decision-maker must stand back and ask what a reasonable person with knowledge of all the circumstances would conclude.

 

Dormant is not necessarily abandoned

 

A lawful use can become inactive or dormant without being abandoned. That distinction is particularly important with commercial yards, industrial land, airfields, storage uses and premises affected by changing markets.

Panton and Farmer v Secretary of State for the Environment, Transport and the Regions [1999] JPL 461 is often cited for the proposition that established lawful use rights can survive a period of dormancy unless they are lost through abandonment, a material change of use or another event which legally displaces them.

There is, however, an important trap. Do not use that proposition to fill gaps in the period needed to make an unlawful use immune from enforcement. In Secretary of State for the Environment, Transport and the Regions v Thurrock Borough Council [2002] EWCA Civ 226, the Court of Appeal made clear that the breach relied upon for enforcement immunity must have existed so that enforcement action could have been taken throughout the relevant period. A sleeping or intermittent unlawful use cannot simply be labelled “dormant” to make the enforcement clock keep running.

So ask which question you are dealing with:

• if the use is already lawful, the issue may be whether those established rights have subsequently been abandoned
• if the use is still trying to acquire lawfulness through passage of time, continuity of the breach is a separate and stricter issue

Our guide to planning enforcement time limits covers that second question.

 

A planning permission is different

 

This distinction is easy to miss. The common-law doctrine of abandonment applies to a use. It does not mean that an implemented planning permission simply vanishes because the developer stops work or says they no longer want it.

In Pioneer Aggregates (UK) Ltd v Secretary of State for the Environment [1985] AC 132, the House of Lords rejected the idea that rights under a planning permission which remains capable of implementation can simply be abandoned by acts of the person entitled to its benefit.

That matters on old development sites. A permission may remain extant even after a very long pause, subject to its conditions and to later events which may affect whether it can still lawfully be completed. For commencement, overlapping permissions and the practical evidence needed to prove a permission is alive, see our guide to making planning extant.

 

What happens if a lawful use has been abandoned?

 

The consequence can be serious. The right to resume that particular use is lost.

In a simple case where it was the site’s only lawful use, the land may be left with no lawful active use and a fresh use may require planning permission. That was the result in Britannia Assets.

Real sites are often more complicated. There may be another subsisting lawful use, an extant planning permission, permitted development rights, a statutory reverter right or a realistic fallback position. Do not assume that proving abandonment answers every other planning question on the site.

 

Abandonment of a dwellinghouse

 

Residential cases are common because an old house may remain physically identifiable long after occupation has stopped.

A house does not lose its C3 use merely because it is empty, unmodernised or in poor repair. But extreme deterioration, a very long period of non-residential occupation or non-use, removal of the things needed for habitation, or positive steps inconsistent with future residential occupation can all matter.

This can be critical where somebody proposes a replacement dwelling in the countryside. If the former residential use has been abandoned, the proposal may no longer be assessed as the replacement of an existing lawful dwelling at all.

Where the status is uncertain, dealing with lawfulness before submitting the replacement scheme can save a great deal of argument later.

 

How do you prove that a use has not been abandoned?

 

Start with evidence rather than assertions. Depending on the site, useful material may include:

• dated photographs and aerial imagery
• business accounts, invoices and customer records
• utility records and rates or council-tax evidence
• leases, tenancy documents and marketing particulars
• maintenance, repair and insurance records
• evidence that essential plant, fixtures or access arrangements were retained
• correspondence showing genuine plans to resume the use
• planning, building control or licensing records
• statutory declarations or witness statements from people with direct knowledge

The evidence should deal with all four abandonment factors rather than focusing only on intention.

If the conclusion matters for a sale, finance, an application or future development, a certificate of lawfulness of existing use or development under section 191 can provide a formal determination. The applicant carries the burden of proving the relevant facts on the balance of probabilities.

 

Abandonment and a certificate of lawfulness

 

A certificate application is not a normal planning application. The council is not deciding whether it likes the use or whether it complies with current development-plan policy. It is deciding a question of law and fact.

If you say a historic use remains lawful, the authority is entitled to examine whether it was ever lawful in the first place and whether later events caused those rights to be lost. Abandonment may therefore become central even where nobody disputes the original planning history.

Good evidence is particularly important because the passage of time tends to remove the very material needed to prove the case. If a potentially valuable old use is becoming dormant, it can be sensible to document the position while witnesses and records are still available rather than waiting until a dispute arises years later.

 

Practical checklist

 

• identify the correct planning unit
• establish precisely what the former lawful use was and how it became lawful
• work out when active use stopped and what happened afterwards
• record the current and historic physical condition of the site
• identify any intervening or superseding use
• collect objective evidence of the owner’s intentions rather than relying on recollection alone
• keep abandonment separate from the enforcement-immunity test in Thurrock
• do not assume an extant planning permission has been abandoned simply because development stopped
• consider a certificate of lawfulness where the answer has commercial or development value

 

Key case law and legislation

 

• Hartley v Minister of Housing and Local Government [1970] 1 QB 413 – established that an existing lawful use can be abandoned
• Trustees of the Castell-y-Mynach Estate v Secretary of State for Wales [1985] JPL 40 – the four familiar abandonment factors
• Hughes v Secretary of State for the Environment, Transport and the Regions [2000] EWCA Civ 506; (2000) 80 P&CR 397 – confirmed the objective approach and the four-factor analysis
• Britannia Assets (UK) Ltd v Secretary of State for Communities and Local Government [2011] EWHC 1908 (Admin) – modern application of the abandonment test to an industrial use
• Panton and Farmer v Secretary of State for the Environment, Transport and the Regions [1999] JPL 461 – dormant established uses and ways in which existing-use rights may be lost
• Secretary of State for the Environment, Transport and the Regions v Thurrock Borough Council [2002] EWCA Civ 226 – continuity when an unlawful use is seeking immunity from enforcement must not be confused with later dormancy of an already-lawful use
• Pioneer Aggregates (UK) Ltd v Secretary of State for the Environment [1985] AC 132 – an extant planning permission is not abandoned in the same way as a planning use
• Section 191, Town and Country Planning Act 1990 – certificate of lawfulness of existing use or development

 

The abandonment question is often worth resolving before money is spent designing a scheme around a historic use. Ask Planning Geek for a fee proposal if you need us to review the evidence, advise on the planning status or prepare a certificate application.
