In 2018, Chelmsford City Council issued a Certificate of Lawfulness confirming that a building in Great Leighs, Essex had been in continuous use as an independent residential dwelling since 2007 — well in excess of the four-year immunity threshold.
The case was resolved through statutory declarations, floor plan evidence and Council aerial photographs, with the officer confirming the evidence was clear, precise and unambiguous.
Certificate of Lawfulness in Chelmsford
Certificate of Lawfulness of Existing Use or Development (CLEUD) was obtained from Chelmsford City Council for a building — a site in the rural area on the southern side of a rural lane.
The Certificate was sought to confirm that the building had been in use as an independent residential dwelling continuously since its construction in 2007, a period well in excess of the four-year immunity threshold that applies to the use of a building as a dwelling house.
The four-year rule under planning law meant that once a building has been in use as a dwelling for four continuous years without enforcement action being taken, that use becomes immune from enforcement and the local planning authority is obliged to issue a Certificate provided the evidence meets the balance of probability standard.
Under established case law, an applicant's own evidence does not require independent corroboration — provided it is sufficiently precise and unambiguous, and the Council has no contradicting evidence of its own.
The detailed evidence package submitted confirmed the building was laid out and fitted out as an independent dwelling — with three bedrooms, a bathroom, kitchen and lounge, a utility room and a dog room, all at a scale commensurate with permanent residential use.
Chelmsford City Council was satisfied that the evidence constituted clear, precise and unambiguous proof of continuous residential occupation for the required period and issued the Certificate under Section 191 of the Town and Country Planning Act 1990.
