Why this matters. The nutrient budget multiplies your scheme's wastewater volume
by the permitted concentration at the works it drains to. A works consented at 27 mg/l of nitrogen
gives a budget nearly three times the size of one at 10 mg/l — and
193 of these 675 works tighten by 2030 under WINEP. Natural
England publish these numbers inside 22 separate Excel workbooks. Here they are
in one place.

All values are mg/l. Bold marks the nutrient the catchment is assessed for; a figure shown lighter is a consent the workbook also publishes for the other nutrient, which is not what your budget is measured against here. Green marks a consent that tightens by 2030. A dash means the workbook carries no figure.

Where these numbers come from
Each catchment's rows are Table 1, the "Stage 1 WwTW lookup", of Natural England's published nutrient calculator for that catchment. The workbook is named against each catchment below. Nothing is estimated: where the workbook has no figure, this register shows a dash.

Read it as a lookup, not as the statutory position
Natural England's published calculator remains the statutory tool, and a permit can be varied by the Environment Agency at any time. This register is here so you can see the whole picture at once and find the works you need in seconds — confirm the consent that decides your scheme against the current workbook, and with the water company where it is marginal.
Four nutrient neutrality catchments are not listed: Oak Mere, Rostherne Mere, West Midlands Mosses and Roman Walls Loughs. Their calculators publish no Stage 1 works lookup — mains drainage is not the route in question there — so there is no permit table to reproduce. They are covered by the calculator all the same.
Turn a consent into a budget
Finding the number is the first step; the budget is the rest of it. NutrientMonkey runs Natural England's methodology for all 27 catchments with this register built in — pick the works and the consent fills itself. Free on screen; the planning-ready PDF is £79 +VAT. If you would rather we ran it, we also prepare nutrient neutrality assessments as a service.

Frequently asked questions
What is a wastewater treatment works permit consent, and why does it change my nutrient budget?
It is the concentration of nitrogen or phosphorus, in mg/l, that the works discharging your development's foul water is permitted to release. The nutrient budget multiplies your scheme's wastewater volume by that consent, so a works permitted at 27 mg/l of nitrogen produces a budget nearly three times the size of one permitted at 10. It is usually the single largest number in the calculation.
Why do some works show a tighter consent from 2030?
Those are the WINEP upgrades — improvements the water company is required to deliver, which Natural England's methodology lets you take credit for once they are in place. Where a works tightens, the budget you have to mitigate depends on when your scheme completes and whether you are buying permanent or temporary credits. 193 of the 675 works in this register tighten by 2030.
Where do these figures come from?
Table 1, the Stage 1 WwTW lookup, of Natural England's own published catchment calculator for each catchment. The workbook each catchment's rows came from is named under its table below. Nothing here is estimated or interpolated — if a value is not in the workbook it is shown as a dash.
Is this the statutory position?
No. Natural England's published calculator is the statutory tool and a permit can be varied at any time by the Environment Agency. Treat this register as a fast lookup and a way to see the whole picture at once; confirm the consent that matters to your scheme against the current workbook and, where it is marginal, with the water company.
Why are four catchments missing?
Oak Mere, Rostherne Mere, West Midlands Mosses and Roman Walls Loughs are nutrient neutrality catchments, but their Natural England calculators do not publish a Stage 1 works lookup — mains drainage is not the route in question there. They are covered by the calculator; they simply have no permit table to reproduce.
