Listed Building Enforcement:
Prosecution, Notices and Reinstatement

Unauthorised Works Are a Criminal Offence

Carrying out works to a listed building that would affect its character without first obtaining Listed Building Consent is a criminal offence under Section 7 of the Planning (Listed Buildings and Conservation Areas) Act 1990. This applies regardless of:

• Whether the owner intended to cause harm
• Whether the works are external or internal
• Whether the works appear to be an improvement
• How long ago the works were carried out
• Whether the current owner carried out the works or bought the property afterwards

Penalties for Listed Building Offences

The penalties available to courts for listed building offences are severe:

• Summary conviction (magistrates' court): unlimited fine and/or up to 6 months' imprisonment
• Conviction on indictment (Crown Court): unlimited fine and/or up to 2 years' imprisonment

In calculating the level of fine, courts are required to have regard to any financial benefit that accrued (or would have accrued) to the convicted person as a result of the offence. This means that if unlawful works increased the market value of the property, the fine may reflect that benefit.

Listed Building Enforcement Notices

Separate from and in addition to criminal prosecution, the Local Planning Authority has power to serve a Listed Building Enforcement Notice (Section 38, Planning (Listed Buildings and Conservation Areas) Act 1990). The notice:

• Identifies the alleged breach
• Specifies the works required to remedy the breach (typically reinstatement)
• Sets a compliance period (usually at least 28 days, often longer for complex reinstatement)

The notice runs with the land. A buyer who purchases the property after the notice is served inherits the obligation to comply. Failure to comply with a Listed Building Enforcement Notice is a further criminal offence and can also lead to the LPA carrying out the required works itself and recovering the costs from the owner.

What Reinstatement May Require

Where a Listed Building Enforcement Notice requires reinstatement, this may include:

• Rebuilding or restoring demolished or removed walls, fireplaces, staircases or panelling
• Removing modern windows and replacing with appropriate traditional windows matching the originals
• Removing cement render or pointing and reinstating lime plaster or mortar
• Removing modern floor coverings and reinstating original floor surfaces
• Restoring altered roof structures to their original form

The cost of reinstatement falls entirely on the current owner. Where original materials no longer exist (for example, original panelling was destroyed), the notice may require the closest achievable approximation. This can be extremely costly.

Appealing an Enforcement Notice

An owner can appeal a Listed Building Enforcement Notice to the Planning Inspectorate within 28 days of the notice being served. An appeal suspends the effect of the notice until the appeal is determined. Grounds for appeal include:

• The works did not affect the character of the listed building
• LBC was not actually required for the works
• LBC has since been granted for the works (retrospective LBC)
• The notice was not properly served
• The compliance period is unreasonably short

Planning inspectors can uphold, vary or dismiss an enforcement notice on appeal. Legal advice is strongly recommended before appealing.

Retrospective Listed Building Consent

It is possible to apply for LBC retrospectively for works already carried out. If retrospective LBC is granted, this can satisfy an enforcement notice. However:

• Retrospective LBC does not confer immunity from prosecution for the original offence
• The LPA may refuse retrospective LBC and then issue an enforcement notice requiring reinstatement
• Retrospective applications are not viewed favourably by conservation officers - they are assessed on the same merits as a prospective application, and the fact that works were carried out without consent is a negative factor

Works in Default

If an owner fails to comply with a Listed Building Enforcement Notice within the compliance period, the LPA has power to enter the property and carry out the required works in default. The LPA can then recover all costs from the owner, including its own costs and the contractor costs. These costs form a charge on the property.

Urgent Works Notices

In addition to enforcement powers, the LPA has power to serve an Urgent Works Notice under Section 54 of the Act where a listed building is in a state of disrepair that threatens its preservation. The notice requires specified urgent works to be carried out within a set period. If the owner does not comply, the LPA can carry out the works and recover costs.

Urgent Works Notices are a conservation tool rather than an enforcement tool - they are used to prevent neglect destroying historic fabric, not primarily to punish deliberate breach. However, an owner who ignores an Urgent Works Notice may face prosecution for the consequences.

Reporting Suspected Breaches

Members of the public can report suspected listed building breaches to the Local Planning Authority's planning enforcement team and to Historic England (for Grade I and II* buildings). Historic England actively monitors its casework and can press LPAs to take enforcement action where they appear reluctant. The Civic Voice and local amenity societies are also useful sources of pressure in cases where LPAs are slow to act.
