It is one of the most common questions sellers ask their agent: do you actually need a floor plan to put a house on the market? The short answer is no, it is not a legal requirement - but leaving one off your listing quietly costs you enquiries, viewings, and time on the market. Here is what the evidence says, and how to produce a portal-ready plan yourself in about ten minutes.
Is a floor plan legally required?
No. In the UK there is no law that forces a floor plan onto a sales listing - unlike the Energy Performance Certificate, which is mandatory. A property can legally be marketed with photos and a description alone. But "allowed to" and "should" are very different things, and buyer behaviour has moved a long way in the last decade.
Why buyers expect one anyway
Portals trained buyers to scroll fast, and a floor plan is the single image that answers the question photos cannot: how does this place actually work? Surveys of buyers repeatedly find that a large majority treat a floor plan as essential, and a meaningful share say they will skip a listing that has none rather than guess at the layout.
- It sets expectations. Buyers see room sizes, flow, and orientation before they book, so the people who do view are the ones the property genuinely suits.
- It reduces wasted viewings. Fewer "the second bedroom is tiny" surprises means a shorter, better-qualified viewing list.
- It supports the asking price. A clear total floor area lets buyers compare like for like against nearby sales.
Tip. Add a north arrow to the plan. "Which way does the garden face?" is one of the first questions a serious buyer asks, and answering it on the plan saves a phone call.
What a good listing floor plan shows
A floor plan that helps sell is not a rough sketch. Aim for a clean, labelled drawing that a buyer can read in seconds:
- Every room labelled, with its area and often its key dimensions.
- Doors and windows in the right places, so the flow between rooms is obvious.
- A total floor area for the whole property (and per floor, if there are several).
- A scale bar and a north arrow, plus your branding on the export.
How to make one in minutes with RoomPlot
You do not need a draughtsman. On an iPhone or iPad Pro, scan each room: walk the perimeter and RoomPlot uses LiDAR to detect the walls, doors and windows automatically. On any other device, draw manually from a room-shape template and let snapping keep the corners square. Either way you get an editable plan in minutes.
- Areas are automatic. RoomPlot detects each room and calculates its floor area from the wall centrelines, so the numbers on your plan are consistent, not estimated by eye.
- Add zone labels with the room name and area at a tap, and a north arrow that bakes into the export.
- Multiple floors? Add each floor and RoomPlot totals the whole project.
Exporting for the portal
When the plan is ready, export a crisp A4 PDF or a PNG at 300 dpi and drop it straight into the listing alongside your photos. Choose an export template - a soft real-estate look or a clean monochrome - and add your company logo and details. If you want a leave-behind for viewings, the multi-page branded report bundles the plan, room areas and photos into one document.
So: not required, but close to expected. For a job that now takes ten minutes, a floor plan is one of the cheapest ways to get more enquiries and sell faster. See our guide to floor plans for property listings for the full workflow, or browse all our guides.
