Gravesham Borough Council has agreed to continue work towards an Article 4 Direction that would require planning permission for small HMO conversions, adding a fresh planning risk for landlords in the Kent borough. The move comes alongside continued enforcement on licensing and unlicensed shared housing.
In a council update published after Tuesday’s cabinet meeting, Gravesham said it had 107 licensed HMOs at the end of March, 14 further licence applications under consideration, and 18 suspected unlicensed HMOs under investigation. The authority said it receives about five reports of suspected unlicensed HMOs each month.
That matters now because Article 4 does not just affect large shared houses already inside licensing rules. It can also catch smaller HMO conversions that would otherwise have gone ahead under permitted development, forcing landlords to think about planning risk before purchase or conversion.
Licensing pressure is now being matched by planning pressure
Gravesham already runs the national mandatory HMO licensing scheme, which applies where five or more people from two or more households share facilities. The council said its controls include occupancy limits, room size standards, fire safety requirements and the fit and proper person test.
The bigger shift for investors is the proposed Article 4 Direction. If adopted, small HMOs would also need planning permission, giving the council more control over where shared housing can be created and how concentrated it becomes.
This follows Landlord Knowledge’s report on Medway’s HMO planning controls moving closer to permanent status. The latest move suggests Kent councils remain willing to tighten both planning and enforcement around shared housing.
Why HMO landlords should take this seriously
For landlords, the practical issue is not only whether the final direction is approved, but how early lenders, valuers and buyers start pricing in that risk. A borough moving toward tighter HMO planning can affect acquisition plans well before the legal change takes effect.
Gravesham also used the announcement to underline its enforcement stance, saying rogue landlords now face a minimum £17,000 fine since the Renters’ Rights Act took effect at the start of May. That makes this more than a dry planning update.
Landlords operating in shared housing should also note that this is part of a wider trend. Landlord Knowledge has already covered similar pressure points in Gloucester and other areas where councils are widening the net around HMOs.
What this means for landlords
- If you’re buying to convert: check whether Article 4 evidence work is under way before relying on permitted development rights.
- If you already run HMOs: make sure licensing, fire safety and room standards are fully up to date.
- Watch for: the next formal stage of Gravesham’s evidence gathering and consultation process.
- Bottom line: in HMO-heavy areas, planning risk is becoming almost as important as rental demand.
Editor’s view
Too many landlords still treat Article 4 as a distant political threat until a deal falls apart. That is a mistake. Once a council is openly building the case, prudent investors should assume the rules may tighten and underwrite deals accordingly.
