Costed bill of materials for a UFH system
Updated 12 July 2026 · Live
What this tool does
Builds a costed bill of materials for an underfloor heating system — pipe, manifold, insulation, screed, controls and labour — with a contingency.
Enter the cost of each element plus labour and a contingency; the calculator totals the system cost.

Builds a costed bill of materials for an underfloor heating system — pipe, manifold, insulation, screed, controls and labour — with a contingency. It runs entirely in your browser and shows the working, so you can check every step against your own figures.
How the underfloor heating cost calculator works
Each element — pipe, manifold, insulation, screed and controls — is a line you price, added to your labour figure. The subtotal is grossed up by the contingency to a total. Every figure is your own, so the estimate tracks the actual products and quotes in front of you rather than a baked-in average.
What you enter
Enter the cost of each element plus labour and a contingency; the calculator totals the system cost. Every field is editable, and the result recalculates the moment you change a value.
Reading the result
The breakdown shows where the money goes; screed and labour often dominate a wet system. Compare the total against an all-in installer quote to see what your own supply-and-fit split saves.
Safe by design
This tool sizes pipe, manifold, coverage and cost. It never sets flow temperatures or heat-source settings — commissioning the system is a qualified heating engineer’s job.
Assumptions and limits
Prices are yours to enter — nothing is embedded, because UFH costs vary with pipe type, floor build-up and region. The estimate excludes the heat source (boiler or heat pump) and its connection, which are a separate and larger cost.
Using it with the rest of BuildMetricLab
This calculator is one step in planning the job. Pair it with the related tools in this category and across BuildMetricLab to go from a single figure to a full costed plan — a sizing figure feeds a cost estimate, a cost estimate feeds a project budget, and each result carries straight into the next tool. Every BuildMetricLab tool runs entirely in your browser — no sign-up, nothing sent to a server, and the formula is shown on the page so the maths can be audited.

Frequently asked questions
What drives the cost of underfloor heating?
Screed and labour often dominate a wet system, with pipe, manifold, insulation and controls making up the rest. Retrofit into an existing floor costs more than new-build.
Does this include the boiler or heat pump?
No — the heat source and its connection are a separate, larger cost. This estimate covers the UFH system itself.
Wet or electric UFH?
This estimates a wet (water) system. Electric mat systems are cheaper to install but usually dearer to run; price them separately.
Why enter my own prices?
Pipe, screed and labour rates vary by product, floor build-up and region, so entering your own quotes keeps the total realistic.
