Floor Plans
A measured floor plan is the cheapest way to make a listing credible. It is not a legal requirement — but the assessor is already measuring every room for the EPC, so it costs far less to add at the same visit than to book separately.
Below: what the plan contains, why it should agree with the EPC, and where a listing is weakest without one.
Is a floor plan a legal requirement?
No. There is no statutory duty to provide a floor plan when selling or letting in England or Wales. The legal document is the EPC, and nothing in the Energy Performance of Buildings Regulations requires a plan alongside it.
That does not make it optional in practice. Portal listings that carry a plan perform better, buyers expect one, and a plan is often requested by the conveyancer or the lender as part of the pack.
What the plan shows
- the layout of each floor, drawn to scale
- room dimensions and room labels
- door and window positions
- the total floor area
- a digital file you can upload straight to a listing
Why it should agree with the EPC
An EPC records a total floor area for the property, and that figure feeds directly into the rating. Where a listing plan contradicts the certificate — a converted loft the plan omits, a room measured generously — the discrepancy is visible to anyone comparing the two.
Measuring both at the same visit removes that risk. The plan and the certificate come from the same set of measurements, so the floor area in the listing matches the floor area on the register.
How it is measured
The plan is drawn from the same measurements taken for the EPC, room by room, so the room sizes in the listing are the room sizes on the certificate rather than an estimate taken from a photograph.
Total floor area is the figure the EPC records, which is why the two should always be read together. If a listing quotes a floor area that does not match the certificate, the certificate is the one a buyer or lender will rely on.
What it does not include
A floor plan is an internal measurement. It is not a site plan, a boundary plan or a land registry plan, and it will not show the position of the property within its plot.
If a transaction needs the boundaries or the site extent — an extension, a sale of part, or a lease plan — that is a separate survey and should be instructed as such. Asking for it at the same visit as the EPC is usually still cheaper than a return trip.
Where a listing is weakest without one
Photographs show finish and light. They do not show scale, circulation or how rooms connect — the three things a buyer is actually trying to work out when they scroll through a listing.
That matters most for:
- Flats, where buyers cannot infer size from the exterior and often cannot tell where the entrance sits.
- Unusual layouts — conversions, split-levels and properties where rooms open off one another rather than a hallway.
- Smaller homes, where a plan demonstrates that the space works rather than leaving a buyer to assume it does not.
Ordered with the EPC
Both are booked through the same quote form and, where access allows, completed on a single visit. If your property also needs a gas safety certificate or an EICR, those can usually be arranged at the same time.
Frequently asked questions
Is a floor plan a legal requirement?
No. There is no statutory requirement to provide a floor plan when selling or letting a property in England or Wales. The EPC is the legal document; the floor plan is a marketing and measuring aid.
Why order a floor plan with an EPC?
The assessor is already in the property measuring every room for the certificate. Producing the plan at the same visit costs less than a separate appointment and avoids a second set of access arrangements.
Will the floor plan match the EPC floor area?
It is measured from the same visit, so the two agree. That matters because the EPC records a total floor area, and a listing whose plan contradicts the certificate invites awkward questions from a buyer or a lender.
What is included in the plan?
An accurate layout with room dimensions, room labels, door and window positions, and the total floor area. It is supplied as a digital file you can drop straight into a listing.
Do I need a floor plan for a flat?
Not by law, but flats benefit most. Buyers cannot judge scale from photographs, and a plan showing the relationship between rooms, the entrance and any outdoor space removes doubt that photographs leave.
Can I get just a floor plan without an EPC?
Yes. Order it through the same quote form, and an assessor will visit to measure the property. Combining it with an EPC is cheaper because the measuring work is shared.
