How the quote is read

Each line of an underfloor heating retrofit quote is matched to the line of the job it names, or marked as something the Wet underfloor heating in an existing floor takeoff does not measure — labour, removal, hire, fees, or anything else. Work the takeoff lists as part of the job but gives no quantity for is read as that work, not as something the quote adds.

The job’s own figures come from 6 measurements — floor to be heated, circuits (loops) off the manifold, manifold to the heated floor, one way, doorways where the new floor meets another, floor sheeted along the route through the house, loose waste, as a depth over the heated floor — run through the same calculators as the takeoff, so the two give the same figure for the same job.

Reading an underfloor heating retrofit quote

An underfloor heating quote rests on a build-up, and two quotes that build the floor differently are pricing two different floors: grooved panels over the old floor under a thin compound, a new screed on insulation where the old one is dug out, or pipe between the joists under the old boards. Worth asking which one each quote assumes, how much it raises the floor at every door and at the foot of the stairs, and who deals with the step that leaves, whether by trimming doors, a strip at the threshold or resetting a bottom step.

The pipe is worth reading with its loops: how many circuits, how long each one runs, the pipe's size and its spacing, and whether those come from a heat-loss design for the room or a spacing picked for the floor alone. Worth seeing named: the manifold with its pump and mixing valve, the edge strip, the insulation and its thickness, the thermostats and wiring centre, and who connects the manifold to the boiler or heat pump and changes its settings for a floor that wants cooler water.

Time is part of the price here. Worth asking when the pipe is pressure-tested and whether it stays under pressure while a screed is laid, how long the screed is left to dry, who runs its warm-up and writes it down, and whether the tiler or floor fitter who follows is booked for after that. The finish is worth confirming product by product: whether the tile adhesive, the underlay or the carpet each quote names is one its maker rates for a heated floor.

Three steps

  1. Give your measurements. The page opens on a typical job so it has something to show.
  2. Paste the quote's lines as they came, or add them one at a time. Leave the prices in — they are taken out, never read.
  3. Read the report: what is left out, what is added, what sits outside the range, and one list of questions to send.

  • What it leaves out

    Every line the job needs that nothing on the quote reads as, with the quantity your measurements produce.

  • What it adds

    Lines this job's takeoff does not measure — labour, removal, hire, fees, anything else — each named for what it is.

  • What sits outside the range

    Quantities above or below the computed range, by how much, in the quote's unit or converted and shown.

  • What to ask

    One list of questions, in the quote's order, ready to copy and send. Questions, never a verdict.

Paste the quote above, or add its lines one at a time. The reading appears here as each line is read.

Outside what this takeoff measures

9

Nothing in the reading measures these. Whether the quote covers each is worth asking in its own right: a scope missing from a quote tends to become a cost after work has started. Why each is left out is on the takeoff.

  • The heat source itself, a boiler or a heat pump, and whether it can run as cool as the loops ask
  • The loop layout, the heat each room's floor gives out and the pipe centres, which the designer sets
  • Whether a suspended timber floor carries a screed's weight, which is flagged
  • Raising door frames, the stair, kitchen plinths or fitted furniture to the new floor level
  • Whether the chosen tiles, boards or carpet suit being heated, beyond naming the question
  • An electric mat or cable system under the floor, which is heated another way; the heated bathroom floor takeoff counts one
  • Removing asbestos the survey finds in the old floor, which is specialist or licensed work with its own programme
  • Damp found in the floor once it is opened up, and whatever damp proof layer or damp-proof course it then needs
  • Redecorating the walls marked where the old emitters hung; making good their brackets and pipe holes is listed

The reference

Every line the reading looks for

For Floor to be heated 220 sq ft · Circuits (loops) off the manifold 2 · Manifold to the heated floor, one way 10 ft · Doorways where the new floor meets another 2 · Floor sheeted along the route through the house 86 sq ft · Loose waste, as a depth over the heated floor 0.59 inFloor to be heated 20 m² · Circuits (loops) off the manifold 2 · Manifold to the heated floor, one way 3 m · Doorways where the new floor meets another 2 · Floor sheeted along the route through the house 8 m² · Loose waste, as a depth over the heated floor 0.02 m. Each is the calculator linked under it, run with those measurements; a range is that calculator at both ends of one choice, not a margin for error.

How the ranges are taken

Where the choice is cutting waste, the ends are the site’s own allowances: 5%, the tight buffer of a crew with a planned set-out, and 15%, the wider one a first-timer orders. Where the calculator decides between patterns or materials, the ends are the options it offers. Where it adds nothing for loss, the range runs from the net quantity to 15% over it.

A minimum — the fewest hangers a spacing allows, the least airflow a room needs — has no upper end. A single figure carries an allowance the material itself needs, such as a lap, and names it.

What a reading like this cannot see

  • It does not know your prices, your market, or what the work ought to cost.
  • It does not know the building — the access, the condition of what is there, or what has to happen first.
  • It cannot check a lump sum, because there is no quantity in one.
  • A line it reads as missing may be priced under another name. A quantity outside the range is not evidence of anything. Each is a reason to ask a question.
  • Two quotes are not comparable until their scopes are.
  • It is not advice, and it is no substitute for a second quote.

Frequently asked questions

What quantities does an underfloor heating retrofit job need?
It depends on the measurements, so this page asks for yours. At the size it opens on — Floor to be heated 20 m² · Circuits (loops) off the manifold 2 · Manifold to the heated floor, one way 3 m · Doorways where the new floor meets another 2 · Floor sheeted along the route through the house 8 m² · Loose waste, as a depth over the heated floor 0.02 m — the lines come to: Grooved panels (low-profile boards), 8 sheets (2400x1200 mm); Pipe loops and leaders (PEX), 156 m of pex; Levelling compound or latex screed (self-leveling underlayment), 120–138 L; Floor tiles, 62–67 tiles; Tile adhesive, flexible, 5–6 bags; Transition strips (door bars, T-moldings) at the doorways, 1.89–2.07 m; Skip (dumpster) for what is taken up, 0.3 m³. In imperial units — Floor to be heated 220 sq ft · Circuits (loops) off the manifold 2 · Manifold to the heated floor, one way 10 ft · Doorways where the new floor meets another 2 · Floor sheeted along the route through the house 86 sq ft · Loose waste, as a depth over the heated floor 0.59 in — they come to: Grooved panels (low-profile boards), 8 sheets (4x8 ft); Pipe loops and leaders (PEX), 524 linear ft of PEX; Levelling compound or latex screed (self-leveling underlayment), 34.3–39.4 gal; Floor tiles, 61–66 tiles; Tile adhesive, flexible, 5–6 bags; Transition strips (door bars, T-moldings) at the doorways, 6.3–6.9 ft; Skip (dumpster) for what is taken up, 0.4 yd³.
Which line on an underfloor heating retrofit quote varies the most?
The Tile adhesive, flexible: 5–6 bags for a job measured Floor to be heated 20 m² · Circuits (loops) off the manifold 2 · Manifold to the heated floor, one way 3 m · Doorways where the new floor meets another 2 · Floor sheeted along the route through the house 8 m² · Loose waste, as a depth over the heated floor 0.02 m, depending on how much is allowed for loss over the net figure, up to 15%.
What does an underfloor heating retrofit quote often leave out?
The reading names every line of the job that nothing on the quote reads as — any of the 7 lines the takeoff measures. The takeoff also lists 9 things it does not measure, shown under the reading, and each is worth asking about: a scope missing from a quote tends to become a cost after work has started.
Can I paste the quote exactly as it came?
Yes — from an email, a PDF or a spreadsheet, one item to a line. Amounts of money are taken out before anything is read, headings and totals are skipped, and each line is shown with what it was read as, so a misreading is one correction. Quantities in the other unit system are converted and the conversion is shown; a count of boxes is never compared with a count of tiles.
Does this check the price as well?
No. It reads quantities, never prices, and this site publishes none: an installed price moves with the market, the season, the access and the specification, so a figure for what the work ought to cost would give you confidence in a number nobody can defend. A quantity against your own measurements is checkable, and every figure here links to the calculator that produced it.
