Certificate of Lawfulness in
Portsmouth
Selling a Portsmouth property with an undocumented loft conversion, or remortgaging one with a change of use nobody ever formalised, often stalls on exactly this question – is it actually lawful? A Certificate of Lawfulness answers that definitively, provided the evidence stacks up.

Two genuinely different situations bring people to this in Portsmouth: something already built or already in use (needing a Certificate of Lawfulness for Existing Use or Development), and something not yet started where you want confirmation in advance it won’t need permission (a Certificate of Lawfulness for a Proposed Use or Development).
For existing situations in Portsmouth, the key legal thresholds are four years of continuous use for building work or a change to use as a single dwelling, and ten years for most other changes of use or breaches of planning condition. Once that period passes unchallenged, enforcement action generally can’t be taken – but proving it requires genuine evidence, not just an assertion.
Before anything formal happens for Portsmouth, our free eligibility check covers your specific situation – existing or proposed, timeline, and what evidence genuinely exists to support it.

How We Help in Portsmouth
Working out which certificate actually applies to Portsmouth – existing use or proposed – and whether the situation genuinely meets the relevant legal threshold comes first, before anything else.
From there, we help gather and organise the evidence your Portsmouth application needs – dated documentation, statutory declarations, anything that builds a clear, defensible timeline for the council to assess.
Because Portsmouth councils can query specific evidence points during determination, we remain available throughout to clarify or supplement whatever’s needed.
The Evidence-First Approach For Portsmouth
Every Portsmouth situation has its own evidence trail, and generic advice can’t account for what’s actually documented versus what would need to be gathered. We check the real picture first.
Portsmouth applications succeed or fail on evidence quality, not quantity – we focus on what actually proves continuous, unchallenged use, not a folder of loosely related documents.
Whether your Portsmouth situation is driven by a sale, a remortgage, or simple peace of mind, we treat the evidence requirement with the same rigour regardless of the underlying reason.

Does my extension qualify under the four-year rule in Portsmouth?
The four-year rule in Portsmouth applies specifically to building operations and changes of use to use as a single dwelling – other changes of use typically need ten years instead.
What is the ten-year rule and does it apply to my Portsmouth situation?
Most other changes of use, and breaches of planning condition, in Portsmouth require ten years of continuous, unchallenged existence before becoming immune from enforcement, rather than the shorter four-year threshold.
What counts as proof for a Portsmouth application?
Dated photographs, utility bills, tenancy agreements, and statutory declarations from neighbours or previous owners are all common evidence types for Portsmouth applications, building a clear continuous timeline.
