NATIONAL GRID PLC (NG.L)

Every figure this model derived for NG.L, the value it took, and the element in the company's own XBRL it was read from — so any of it can be checked against the filing rather than taken on trust. As at 2026-03-31.

The figures, and where each came from

This is the part no other screener shows. Each figure below names the XBRL element it was read from, so it can be checked against the filing itself.

What to be careful about

What this model itself distrusts about NG.L's figures. Written by the derivation as it ran, not added afterwards.

revenue is annual, not TTM
operating income is annual, not TTM
no usable diluted share count, so growth is measured on total revenue rather than per share; a company issuing shares to fund that growth reads better than it is
no forward EPS estimate; growth rests on filings only. Analyst consensus is not published in XBRL, so it has to be fetched from a data provider or set by hand in overrides.yaml as `eps_growth_2y`
quality rests on 4 of 5 inputs; not tagged: owner earnings
valuation rests on 1 of 2 inputs; not tagged: ev owner earnings
durability DROPPED from the total: only 0 of 4 inputs could be computed (worst year, contracted coverage, gross margin stability, cash flow stability not tagged), so the score is not meaningful. Its weight is spread over the other dimensions
growth DROPPED from the total: only 1 of 4 inputs could be computed (sustained growth, margin trend, margin recent not tagged), so the score is not meaningful. Its weight is spread over the other dimensions
2 of 5 dimensions could not be measured (durability, growth -- 30% of the model), so this row is not comparable with the others; its total rests on what was left
