The George Baldock enforcement appeal: concealment defeats immunity

The George Baldock enforcement appeal has ended with North Herts Council successfully defending its action over the listed former hotel, which had been changed to 21 unauthorised residential flats.

The owner relied on the historic four-year enforcement period. Following a public inquiry, the Planning Inspector dismissed the appeal and upheld the notice. The Inspector accepted that the relevant residential use had existed for at least four years, but found that deliberate positive deception prevented the appellant relying on the historic immunity period.

The full appeal decision APP/X1925/C/26/3378008 and the separate costs decision are available in the Planning Geek library.

What does the council say happened?

The George is a listed former public house and hotel in Hitchin Street, Baldock. North Herts Council says it investigated a material change of use from hotel accommodation to 21 residential flats, with occupiers living in sub-standard accommodation.

The enforcement notice required the unauthorised residential use to cease and the kitchenettes in the rooms to be removed. The owner appealed, and the matter was considered at a public inquiry.

The council says the Inspector found that the residential use had been hidden from the authority for more than four years and that deliberate steps had been taken to conceal it while officers were investigating.

The George Baldock enforcement appeal outcome

According to the council’s official announcement:

• The enforcement appeal was dismissed
• The enforcement notice was upheld
• The residential use must end
• The kitchenettes in the rooms must be removed
• The compliance period is six months, ending in February 2027
• The appellant’s application for costs was refused because the council had not acted unreasonably

The appeal proceeded on ground (d) only. Crucially, the Inspector accepted that the first- and second-floor residential use had, on the balance of probability, begun on or before 15 January 2022 and continued for at least four years. The appeal nevertheless failed because the Inspector found positive deception which prevented the appellant relying on the historic section 171B(2) time limit.

The hotel permission did not authorise residential flats

There was a 2024 permission for part of the ground floor to become four additional hotel rooms in Use Class C1, but that did not authorise self-contained residential flats. The Inspector’s costs decision records that the ground-floor residential units were not appealed and were therefore accepted to be without planning permission.

That distinction matters because the appeal concerned the residential use itself, not whether hotel rooms had been lawfully created.

Why was the historic four-year rule relevant?

Before 25 April 2024, section 171B of the Town and Country Planning Act 1990 generally gave an authority four years to act against operational development and a change of use of a building to use as a single dwellinghouse. Most other material changes of use had a ten-year period.

The law in England changed on 25 April 2024. The general enforcement period is now ten years, subject to transitional provisions which preserve the relevance of the former four-year rule for some earlier development and uses.

That is why an appeal decided in 2026 can still involve a four-year immunity argument. The alleged breach began under the previous regime, and the transitional rules have to be applied to the facts. Our guide to planning enforcement time limits explains the present and historic position.

Years of occupation do not prove the whole case

An appellant relying on immunity normally carries the burden of establishing the case on the balance of probabilities. The evidence must prove the planning breach relied upon, when it began and whether it continued throughout the relevant period.

For an alleged use as self-contained flats, useful evidence may include:

• The physical layout and facilities of each unit
• Tenancy agreements, rent records and deposit information
• Council tax or business rates records
• Utility accounts and official correspondence
• Electoral registration and address records
• Dated photographs, plans and contractor invoices
• Consistent evidence from occupiers and neighbours

A hotel booking, a tenancy label or evidence that somebody slept in a room does not necessarily prove a continuous use as a separate dwelling. The character of the occupation and the facilities provided matter.

Deliberate concealment and Welwyn Hatfield

The leading authority is Welwyn Hatfield Borough Council v Secretary of State for Communities and Local Government and Beesley [2011] UKSC 15.

Mr Beesley obtained permission for a hay barn but built and occupied a dwelling designed to appear externally as the approved agricultural building. The Supreme Court held that he could not rely on the statutory time limit where positive deception was integral to the very use for which immunity was claimed.

The principle is not that every unauthorised development or failure to apply for permission is concealment. Plenty of planning breaches are carried out openly and can become immune after the applicable period. The exceptional issue is positive, deliberate deception which prevents the authority discovering the true breach.

The Inspector found that this case fell squarely within that territory. He identified misleading descriptions of short hotel-style stays in 2022, false answers to the January 2025 PCN about tenancy agreements, incomplete disclosure of occupiers’ length of stay, restricted access to rooms and attempts to prevent officers speaking directly to occupiers. Taken together, he found those actions amounted to deliberate positive deception.

Concealment does not simply stop the clock

It is tempting to reduce this area of law to the slogan that concealment “stops the clock”. That is too loose and can lead owners badly astray.

There are several separate questions:

• What planning breach actually occurred
• When it began and whether it continued
• Whether the evidence proves immunity on the balance of probabilities
• Whether positive deception prevents reliance on the time limit under the Welwyn Hatfield principle
• Whether the authority used or needed the statutory planning enforcement order regime

The answers depend on the facts and the legal route being used. Concealment can remain highly relevant, but it is not a universal rule that any hidden feature automatically resets an enforcement period.

What is a planning enforcement order?

Sections 171BA to 171BC of the 1990 Act allow an authority to ask the magistrates’ court for a planning enforcement order where an apparent breach has been deliberately concealed and the ordinary time limit has expired.

The authority must act within six months of having evidence which is sufficiently clear to justify an application. If the order is made, it creates a further period in which enforcement action can be taken.

No planning enforcement order was sought in this case. The Inspector expressly relied on Jackson v Secretary of State for Communities and Local Government [2015] EWHC 20 (Admin), which confirms that the Welwyn Hatfield public-policy principle can still be invoked without a PEO. That is why the two routes should not be treated as interchangeable.

The compliance requirements matter

The notice was not simply a declaration that the flats lacked permission. It requires practical steps: the residential use must end and the kitchenettes must be removed within six months.

Failure to comply with an upheld notice after the compliance period can be a criminal offence. Owners and occupiers should therefore treat the deadline as an operational issue as well as a legal one, particularly where residents need to be rehoused.

Practical lessons for owners and purchasers

• Do not assume a number of years’ occupation automatically proves immunity
• Identify the precise planning use rather than relying on tenancy labels
• Make sure rates, council tax, advertising and physical layout tell a consistent story
• Do not mislead officers or ask occupiers to do so
• Obtain a formal Certificate of Lawfulness where a transaction depends on lawful status
• Act immediately when an enforcement notice is served because appeal deadlines are strict

A long occupation may be powerful evidence, but it is not a substitute for a coherent case. The George is a useful warning that deliberate attempts to preserve the appearance of an authorised use can undermine the very immunity argument an owner later wants to make.

The appellant’s costs application was also refused

The separate costs decision is useful in its own right. The Inspector refused the appellant’s application for a full award of costs and rejected each allegation that the Council had acted unreasonably.

• Re-opening the enforcement investigation was not inherently unreasonable
• There is no separate statutory deadline for completing an enforcement investigation beyond the relevant enforcement time limits
• The appellant’s failure to answer the January 2025 PCN frankly and fully materially contributed to the length of the investigation
• Suggesting that an owner who considers a use lawful should apply for a Lawful Development Certificate was a reasonable course for the Council to propose
• The Council was entitled to proceed with formal enforcement rather than entertain a regularising application
• No unreasonable behaviour causing unnecessary or wasted expense was established

The costs decision therefore reinforces the wider lesson from the appeal: owners relying on immunity need clear evidence, but they also need to have dealt candidly with the authority throughout the enforcement process.
