Earlier than I make investments any hard-earned cash in a inventory with the purpose of securing long-term passive earnings, I wish to run via just a few guidelines gadgets.
Not every little thing will come out tops on each one. However the extra passes than fails the higher, and it helps me kind my choices into some sort of precedence.
I’ll run via it right this moment with a inventory from my candidates record, Nationwide Grid (LSE: NG.)
Examine 1: dividend
Is a dividend important? Anybody who purchased Rolls-Royce Holdings shares in 2020 may promote some for money now. They usually’d doubtlessly get extra passive earnings than from 20 years of Nationwide Grid dividends.
However dividend shares are usually much less dangerous and require much less consideration. I purchase shares within the hope of by no means having to consider when to promote.
Nationwide Grid has a forecast dividend yield of 4.3%. It’s not the most important within the FTSE 100, however it’s affordable and it passes verify #1.
Examine 2: cowl
I wish to really feel moderately assured that an organization can maintain paying its dividends from earnings.
Nationwide Grid hasn’t at all times managed to do that. However over the long run, we’ve seen earnings masking the dividend round 1.1 to 1.2 occasions, reaching 1.3 occasions for the 2025 12 months simply ended.
Once more, that’s not one of the best. However there’s good long-term earnings visibility, which may imply much less earnings security margin wanted. Examine #2 is nice sufficient for me.
Examine 3: historical past
Saying that, 2025 cowl was larger as a result of the corporate minimize its dividend per share. The full money payout was the identical, however final 12 months’s shock fairness increase to generate new capital meant extra dilution per share.
Previous to that we’d had a few years of strong progressive dividends. And I’d, maybe naively, have thought a minimize was close to not possible. I now worry the potential for additional fairness points inflicting extra dilution. I’m not sure, so I’ll go 50/50 on #3.
Examine 4: forecasts
Wanting ahead, the corporate has reiterated its purpose to pay extra in dividend money annually. And forecasts presently bear that out, displaying 1.8% and a pair of.2% will increase for 2026 and 2027, respectively. They’re not massive jumps, however ought to hopefully match inflation.
I’d ideally wish to see few extra years of Nationwide Grid again to progressive dividends with none additional dilution. However I give it a cautious move on #4 for now.
Examine 5: debt
I at all times verify debt for each firm I think about, as it may well affect the dividend throughout a tricky spell. Nationwide Grid’s web debt reached £41.4bn in 2025. And it’s forecast to achieve as excessive as £52.8bn by 2027, for a 27% improve in simply two years. Examine #5 is a transparent fail.
Verdict
These checks aren’t complete. And each firm can have its personal particular dangers which we actually want to research. However I see this as a helpful begin.
I’ve typically considered Nationwide Grid as presumably one of the best dividend inventory I’ve by no means purchased. But it surely solely scores 3.5 out of 5 (and a type of is cautious). I nonetheless assume passive earnings buyers ought to think about it. However within the brief time period, different shares rating higher on my guidelines.
