Virtual staging is the process of digitally adding photo-realistic furniture, lighting, and decor to photographs of empty or unfurnished properties, helping buyers visualise how a space could look without the cost of physical staging.

Matterport is a 3D scanning technology and platform that captures interactive virtual tours of indoor spaces, widely used in real estate to give buyers a navigable 3D walkthrough of a property online — typically embedded in listing pages.

HDR (high dynamic range) blending is a real estate photo editing technique that merges multiple bracketed exposures of the same room — one for bright window highlights, one for mid-tones, one for shadows — into a single image that retains detail across the full tonal range.

Flambient editing is a real estate photo editing technique that blends multiple flash-lit and ambient-lit exposures of the same room into one balanced, photo-realistic image with magazine-quality colour accuracy.

Day-to-dusk is a real estate photo editing technique that digitally converts a daytime exterior property photo into a striking evening or dusk scene — with warm sky tones, illuminated windows, and ambient lighting — eliminating the need to schedule a separate twilight photoshoot.

An Energy Performance Certificate (EPC) is a mandatory UK document that rates a property's energy efficiency from A (most efficient) to G (least efficient). An EPC is legally required for any property being sold, rented, or built in England, Wales and Northern Ireland, and is valid for ten years.

An HMO (House in Multiple Occupation) is a UK rental property occupied by three or more unrelated tenants who share kitchen, bathroom, or toilet facilities. Large HMOs with five or more tenants require a mandatory licence from the local council; smaller HMOs may need additional or selective licensing depending on the borough.

HMLR stands for HM Land Registry — the UK government department responsible for registering ownership of land and property in England and Wales. HMLR also sets the formatting standards for lease plans submitted alongside leasehold property transactions, conveyancing and lease extensions.

GIA (Gross Internal Area) is the total floor area of a property measured from the inside of the external walls — including circulation space (hallways, stairs), internal walls, and built-in storage, but excluding voids, external walls, and unenclosed external balconies.

RdSAP (Reduced data Standard Assessment Procedure) is the UK government's methodology for assessing the energy efficiency of existing residential properties for Energy Performance Certificates. It uses simplified inputs gathered during a site survey rather than the full SAP calculation used for new builds.
