R (John Childs) v First Secretary of State and Test Valley Borough Council [2005] EWHC 2368 (Admin)

The Childs caravan case concerns an increase in the number of residential caravans on land already covered by a lawful development certificate. The High Court held that an increase could amount to a material change of use where the certificate validly described the existing use by reference to caravan numbers. Whether the change was material remained a question of fact and degree.

Decision and later history: the High Court refused the challenge on 18th October 2005. The judge granted permission to appeal. We have not verified a later appeal outcome, so this page explains the High Court judgment and its limits.

CO/2689/2005

What happened at Chilbolton?

The case concerned a 2.5 hectare field adjoining the Leckford Hutt public house at Chilbolton, Hampshire. On 24th April 2003, Test Valley Borough Council issued a certificate under section 191 of the Town and Country Planning Act 1990 describing the lawful use as a residential caravan site for four caravans. The certificate applied to the whole field, but its description expressly included that number.

John Childs subsequently sought certificates under section 192 for proposed use of the site for eight, 15, 30 and 50 residential caravans. The council refused all four applications, and an Inspector dismissed the appeals on 24th March 2005. Mr Childs then challenged that decision under section 288.

The legal argument was specific. Mr Childs said that increasing the number of caravans could not amount to a change of use at all because the land would remain a residential caravan site. He did not challenge the Inspector’s factual finding that the change would be material if it was legally capable of being a change of use. That distinction is set out in paragraphs 3 and 14 of the judgment.

What the Childs caravan case decided

James Goudie QC rejected that argument. A residential caravan site did not fall within a use class, and the council was entitled, although not obliged, to describe its lawful use by reference to the intensity of that use. The four-caravan description in the 2003 certificate was lawful and had not been challenged at the time.

In paragraphs 25 to 27, the judge explained that the existing use and the proposed use could be identified by reference to scale. A site lawfully used for four residential caravans could become materially different in character if it accommodated eight or more. Calling both uses a residential caravan site did not prevent that comparison.

Paragraph 33 gives the central qualification: intensification does not necessarily amount to a material change of use, but neither is a change of use excluded merely because the broad description stays the same. At paragraph 38, the judge found no error of law in the Inspector’s approach and refused the application.

Why the numbers mattered on this site

The Inspector considered the site’s rural setting, its appearance in the landscape, activity on the land and traffic movements. Four caravans would leave the field appearing generally open and little used. In the Inspector’s assessment, eight would give it a materially different character. The judgment records that reasoning in paragraphs 9 to 13.

The council accepted that an increase from four to five caravans would not be materially different. The proposed increase from four to eight had been found material as a matter of fact and degree. Those findings were specific to this site. The judgment does not establish a national numerical threshold or a rule that doubling caravan numbers always requires planning permission.

Read the certificate before relying on the case

The wording of the existing certificate was central. Its reference to four caravans was part of the lawful use that had been certified. The judge rejected an attempt to treat that reference as irrelevant and held that the certificate could not be challenged indirectly in these proceedings. He also concluded that such a challenge would fail on its merits, as explained in paragraphs 31 and 32.

At paragraph 28, the judge discussed what the position might have been if the certificate had said nothing about numbers. That was a hypothetical observation. The certificate before him did specify a number, so we should not turn that passage into a blanket right to place unlimited caravans on any land with a broadly worded certificate.

The case also does not determine the effect of every separate planning condition or site-licensing requirement. Those questions need the relevant documents and their own analysis.

How we would use this judgment

For a proposed increase in activity, we would start with the evidence rather than assume that retaining the same general use label settles the question:

• Read the exact certificate, its plan and the description of the established lawful use
• Compare the proposed scale and character of activity with that lawful baseline
• Consider the planning consequences, including appearance, on-site activity and traffic, where they are relevant to whether the character of the use would materially change

Our Swale caravan appeal report considers a separate dispute about a historic landscaping condition and the limits of the certificate sought there. Childs was referred to in that appeal, but it did not decide the narrower issue before the Inspector.

Permission to appeal

The transcript includes the discussion after judgment. At paragraphs 71 and 72, the judge granted permission to appeal because the point of law was important and earlier judicial observations conflicted. At paragraph 82, he allowed 28 days for the appeal notice. Permission to appeal is not an appellate ruling. We have not verified whether a later appeal proceeded or how it was disposed of.
