Waltham Forest: compare the actual use
Secretary of State for Transport, Local Government and the Regions v Waltham Forest London Borough Council [2002] EWCA Civ 330 is important when deciding whether a proposed use needs planning permission.
The comparison is between the actual existing use and the proposal. It is not enough to invent an intermediate use, argue that each individual step would be lawful, and assume that the direct change must therefore be lawful too.

A house proposed for residents receiving care
The applicant sought a proposed-use certificate for six people recovering from mental ill health, living together with care provided. The inspector rejected the claim that both uses fell within the same use class, but concluded that the proposal would not involve a material change.
In doing so, the inspector compared it with occupation by a hypothetical large family. He had not investigated how the house was actually used at the application date.
The High Court quashed the certificate. The Court of Appeal dismissed the Secretary of State’s appeal and upheld that result.
Two apparently lawful steps do not answer the question
The Secretary of State argued that occupation by a large family would be lawful, and that changing from that arrangement to the proposed care use could be non-material.
The court rejected the conclusion that this necessarily made the direct change lawful. Paragraph 14 uses intensification to illustrate the problem: a series of individually modest increases does not mean that the difference between the beginning and end can never be material.
Paragraphs 17–18 explain why the notional intermediate use did not belong in the particular material-change comparison required for the certificate.
A fallback belongs to a different question
The court accepted that the possibility of other lawful uses could be relevant when deciding whether to grant planning permission for the proposal.
That is a planning-merits assessment. A lawful development certificate instead asks whether the proposal already has the necessary permission or does not require it. The two exercises should not be substituted for one another.
What this case does not decide
The inspector’s conclusion about the proposed use falling outside the historical C3 class was not challenged before the Court of Appeal. The judgment should not therefore be treated as a comprehensive ruling on every modern supported-living or care arrangement.
Nor does it erase an accrued lawful use simply because that use is dormant. Paragraph 19 expressly agreed with the relevant principle in Panton and Farmer, while explaining why it did not answer the different question in this appeal.
For practical advice, establish the actual use and planning history, describe the proposal precisely, and identify the legal basis on which it is said to be lawful.
