What a turnkey interior actually costs — and where the money goes

An honest breakdown of joinery, electrical, ceiling, painting and styling, plus the three line items that quietly wreck budgets.

Interior quotations are hard to compare because two firms rarely describe the same scope. Here is how the money is actually distributed in a typical turnkey residential interior, and which items deserve your attention.

Where the budget goes

  • Joinery and wardrobes — usually the single largest share. Driven by carcass material, shutter finish and hardware brand.
  • Kitchen — cabinetry, counter, backsplash, chimney and hob. Small in area, large in cost per square foot.
  • Electrical and lighting — rewiring, points, switches, layered lighting. Cheap to plan, expensive to change later.
  • False ceiling and painting — the finish everyone notices; also the easiest place for a quotation to hide thin work.
  • Flooring and dado — only where existing surfaces are being replaced.
  • Soft furnishing and styling — curtains, upholstery, art, plants. Frequently omitted from quotes, then added.

The three items that break budgets

First, hardware. Hinges, channels and handles are invisible in a render and decide whether the kitchen still works in year five. Second, plywood grade — the difference between commercial and boiling-water-proof ply in a coastal climate like ours is not cosmetic. Third, scope creep on site: every mid-project change costs more than the same decision made at drawing stage.

How to compare two quotations fairly

  • Insist on a room-by-room, item-by-item BOQ rather than a lump sum.
  • Ask for named brands and grades for ply, laminate, hardware and wiring.
  • Check whether electrical, false ceiling, painting and curtains are included or excluded.
  • Confirm who supervises daily, and how often you receive progress photographs.
  • Get the timeline and the payment stages in the same document.

We publish an itemised BOQ before work begins for exactly this reason: a budget you can read is a budget you can hold us to.
