This is the question agencies get wrong most often, usually not deliberately. A board goes up, the property sells, the file closes, and nobody schedules the lift. Three months later it is still there, faded, and someone complains.
The rule
- A for sale or to let board can stay up while the property is being marketed.
- It must be removed within 14 days after the sale is completed or the tenancy is granted. That is the wording of the condition, and it runs from completion, not from the offer being accepted.
- A Sold or Let Agreed message can only be added to the existing board. A separate Sold board is not covered.
- Only one board (or two joined boards) is allowed per property. If more than one goes up, the first one displayed is the lawful one.
All of this comes from Class 3 of Schedule 3 to the Planning (Control of Advertisements) Regulations (Northern Ireland) 2015. We have set out every condition, including the size and height limits, in our guide to estate agent board rules in Northern Ireland.
When the council can step in
A board that breaks any of those conditions loses its deemed consent and becomes an unauthorised advertisement, which councils can pursue through their planning enforcement teams. Councils can also ask for deemed consent to be withdrawn in a particular area or case, so a sensitive street can be treated more strictly. Blocks of flats are different again: the management company usually has its own rules that have nothing to do with planning.
The practical fix
The reason boards overstay is almost never a policy decision. It is that removal is nobody's job. The agencies that never get complaints are the ones where the removal is triggered by the same system that triggered the Sold slip, so it happens without anyone remembering.
That is exactly what our ordering system does for the branches that use it: the removal is raised as a job, and it goes on the van route with everything else in that area.
This is general guidance for Northern Ireland and not legal advice. If a specific property is sensitive, check with the local council planning office.
