National Grid plc (NG.L): Valuation Snapshot
National Grid plc (NG.L) is a rate-regulated utility, and a discounted-cash-flow model is the wrong lens for one, so TickerWorth does not publish a DCF fair value for it. What its filings and market data do show is below. Snapshot as of Oct 19, 2026.

Why is there no fair value for NG.L?
This is a rate-regulated utility. Its returns are set by a regulator on an approved rate base rather than won in a market, so a free-cash-flow DCF is the wrong lens — heavy ongoing capex is the business model, not a cash-flow problem. We show the regulated-asset lenses — book value, earnings and dividend — instead.

What we can say
National Grid plc (NG.L) is a rate-regulated utility, and a free-cash-flow discounted-cash-flow (DCF) model is structurally the wrong lens for one. Its returns are not won in a market — a regulator sets them on an approved rate base — and the heavy, permanent capital spending that depresses its free cash flow is the business model rather than a problem with it. We have the data to print a DCF number for NG.L; we don't publish one because the model's assumptions don't describe how this company actually earns. What follows is the lenses that do — descriptive, not a valuation, and not investment advice.
Read the full reasoning
On the numbers we do have, NG.L trades at a recent price of £11.89, a market capitalisation of about £59,795,083,264, sitting 28% of the way up its 52-week range (£10.96–£14.29), on the LSE.
The standard alternative to a DCF is relative valuation — comparing NG.L's trading multiples against a sector benchmark. Here that gives P/E of 18.0× (cheaper than the peer median of 22.0×); Fwd P/E of 12.2× (cheaper than the peer median of 18.2×); P/B of 1.5× (cheaper than the peer median of 2.2×); P/S of 3.4× (in line with the peer median of 3.1×); EV/EBITDA of 15.0× (in line with the peer median of 13.7×); Dividend yield of 4.0% (cheaper than the peer median of 3.3%). A cheaper multiple than peers can flag a discount or a market that expects weaker growth; it is a comparison, not a recommendation.
The asset, or book-value, lens is the classic tool for asset-heavy businesses and financials. NG.L shows a price-to-book (P/B) of 1.51 and book value of £7.90 per share. Price-to-book compares the market price to the accounting net-asset value per share; below 1.0 can mean a discount to net assets or that the market is pricing in trouble — descriptive either way, never a buy signal on its own.
Finally, a price-based read — explicitly not a valuation. NG.L is in a mixed trend, trading -16.7% from its 52-week high. Over the past year the stock is +7.6%. Moving-average trend and 52-week position describe where the stock has traded; they say nothing about what it is worth.
To be exact about what this page is not: we are not saying the numbers for NG.L are unavailable. They are, and they are above. We are saying a discounted-cash-flow model is the wrong instrument for this kind of business, and publishing one anyway — because the inputs happen to exist — would be a precise answer to the wrong question. Refusing is the more useful answer, and it is the same rule we apply to every name in this category.
