Performance Benchmarking
Compare your site against UK construction industry averages
What is benchmarking?
UK benchmarks show how your site compares by project type. Performing better than
average is powerful evidence for tender submissions and endorsing bodies.

Small Sites Metric where the scheme qualifies

What is Biodiversity Net Gain (BNG)?
Biodiversity Net Gain (BNG) is a legal requirement under the
Environment Act 2021. Most new developments in England must deliver at least a
10% net gain in biodiversity compared to the pre-development
baseline.
Defra's Statutory Biodiversity Metric is the official
government tool for measuring biodiversity in habitat units, and the one
planning submissions must use. It scores habitats on type, area or length,
condition, strategic significance, how long the habitat takes to reach its
target condition, and how technically difficult it is to create or enhance.
Area habitats, hedgerows and watercourses are measured separately and their
units are not interchangeable — each must meet the 10% requirement on its own.
How to use this calculator: Step 1 — enter all habitats
present on site today (before development). Step 2 — enter all habitats
proposed after development. Step 3 — review your net gain result and save.
Baseline — Area Habitats
Enter existing habitats on site before any development works.
130+ habitat types including grassland, woodland, wetland, heathland,
coastal and urban habitats, per Defra's Statutory Biodiversity Metric
Baseline — Linear Features
Hedgerows, watercourses, and other linear habitat features on site.
Includes hedgerows, watercourse margins, woodland edges, and other linear
features
Add all habitats present on site today — before any works begin.

Post-Development — Area Habitats
Enter habitats proposed after development. Mark each row as
creation (making habitat where there is none today) or
enhancement (improving habitat you are keeping) — Defra scores them
differently, and neither is automatically the better option. The time-to-target
discount and the technical difficulty multiplier are applied automatically from
Defra's published figures for the habitat, the intervention and the
conditions you choose.

This scheme needs the full statutory metric
Defra's Small Sites Metric is on every plan, including Free — but only schemes
that qualify may use it, and the screening above says this one does not. The full
Statutory Biodiversity Metric covers on-site baseline, habitat creation and
enhancement across area habitats, hedgerows and watercourses, but not off-site gains,
trading rules or credits — so formal submissions must still be made with Defra's
own calculation tool. Available on the
Pro plan and above.

Scope 1 — Direct
Emissions your company directly controls: diesel generators, petrol plant, company
vehicles, gas on-site.
2
Scope 2 — Purchased Energy
Electricity bought from the grid for site offices, welfare units, and temporary
power.
3
Scope 3 — Value Chain
Embodied carbon in materials, supplier deliveries, subcontractor travel, and waste
disposal.

Log Waste Entry
This stream may be hazardous. Under WM3 it is a mirror entry
(soil 17 05 03*/17 05 04, paint
08 01 11*/08 01 12) — only your assessment of the
material decides which applies. We have suggested a hazardous route; change it if
your assessment says otherwise. Pick the route by how the waste is actually
treated — DEFRA charges a licensed landfill cell gate-to-grave, and
incineration as transport only.
