Is National Grid Plc NGG stock Halal to invest in?

No, as of September 2026, National Grid Plc stock (NGG) is not currently classified as a Shariah compliant stock. This verdict follows the screening methodology of AAOIFI (the Accounting and Auditing Organization for Islamic Financial Institutions), whose Shariah Standard No. 21 is the leading global benchmark for screening Halal stocks. To qualify as Halal under this standard, a company must keep non-permissible income below 5% of total revenue, keep both interest-bearing investments and interest-bearing debt below 30% of market capitalisation, and have no impermissible preference share structure. National Grid Plc currently does not meet the threshold for the interest-bearing debt screen. Because screenings are refreshed monthly as new financial reports are published, a non-compliant stock can regain compliant status if its financial structure changes. You can track the latest status of National Grid Plc and discover Shariah compliant alternatives among the Halal stocks in the Tabadulat app.

How often is National Grid Plc NGG reviewed for Shariah compliance?

Tabadulat reviews National Grid Plc NGG for Shariah compliance every month. Each review applies the AAOIFI Shariah Standard No. 21 methodology, screening the company's business activities, non-permissible income, interest-bearing investments, interest-bearing debt, and preference shares, against the company's latest available financial data. The process operates under the direct supervision of Tabadulat's dedicated Shariah Supervisory Board of Islamic finance scholars. Because compliance depends on financial ratios that move with market capitalisation and reported results, a stock's status can change from one review to the next. Monthly screening ensures the status shown for National Grid Plc reflects current financial data rather than an outdated assessment, and Tabadulat app users are notified if a holding in their portfolio becomes non-compliant.

Does National Grid Plc NGG pass the AAOIFI Non Permissible Income criteria?

Yes, as of September 2026, National Grid Plc stock (NGG) passes the AAOIFI non-permissible income screen. AAOIFI permits a small tolerance because large companies rarely avoid incidental impermissible income entirely, most often interest on cash balances. The ceiling is 5% of total revenue, and National Grid Plc sits inside it in the latest screening. Even permissible levels of incidental impure income should still be purified: investors donate the corresponding share of dividends to charity, as reflected in the stock's purification factor. This screen is reassessed monthly using the company's latest financial disclosures.

Does National Grid Plc NGG pass the AAOIFI Interest Bearing Investments criteria?

Yes, as of September 2026, National Grid Plc stock (NGG) passes the AAOIFI interest-bearing investments screen. AAOIFI caps interest-earning holdings at 30% of market capitalisation so that shareholders do not materially profit from Riba. Measured against the latest data, National Grid Plc's interest-bearing investments sit within the limit. Because the ratio is measured against market capitalisation, it can move with the share price as well as the balance sheet, which is why Tabadulat rescreens the stock every month.

Does National Grid Plc NGG pass the AAOIFI Interest Bearing Debt criteria?

No, as of September 2026, National Grid Plc stock (NGG) does not pass the AAOIFI interest-bearing debt screen. Under AAOIFI Shariah Standard No. 21, a company's borrowings that accrue interest (conventional bank loans, bonds and similar Riba-based financing) must remain below 30% of its market capitalisation. National Grid Plc's interest-bearing debt currently exceeds this 30% limit, meaning the company relies on Riba-based financing beyond the level AAOIFI permits for a Halal investment. A company can return to compliance by reducing debt or through changes in market capitalisation, and the screen is reassessed monthly.

What is the dividend purification factor for National Grid Plc NGG stock?

National Grid Plc (NGG) is currently classified as not Shariah compliant, so no dividend purification factor applies, because purification factors are calculated only for stocks that pass the AAOIFI screens. Purification (Tazkiyah) is the practice of donating to charity the small portion of dividend income that stems from incidental non-permissible sources, such as interest earned on a compliant company's cash deposits. For non-compliant stocks the issue is not purification but eligibility: under AAOIFI Shariah Standard No. 21 the stock does not currently qualify as a Halal investment. If National Grid Plc returns to compliance in a future monthly screening, its purification factor will be published alongside its updated status in the Tabadulat app.

Does National Grid Plc NGG pass the AAOIFI Preference Share screen?

Yes, as of September 2026, National Grid Plc stock (NGG) passes the AAOIFI preference share screen. AAOIFI Shariah Standard No. 21 prohibits investing in preference shares because they grant holders guaranteed or priority rights to dividends and capital ahead of ordinary shareholders, a structure that conflicts with the Shariah principle that investors should share profit and loss in proportion to their ownership. National Grid Plc has no impermissible preference share structure affecting its ordinary shares, so the stock is compliant on this criterion. Like all AAOIFI screens, this is verified in each monthly review.

National Grid represents American Depositary Receipts of National Grid a leading multinational utility company headquartered in the United Kingdom. This ADR allows US investors to participate in the performance of National Grid without having to directly purchase foreign shares. National Grid is primarily engaged in the transmission and distribution of electricity and gas. For Muslim investors, though, the most pressing question is simpler: is National Grid a Halal investment?

Is National Grid Shariah compliant?

Finance is the sector where Shariah screening does the most work, because Riba is not incidental here, it can be the product itself. National Grid passes the business activity screen only if its revenue comes from permissible services rather than lending at interest, and the financial screens of AAOIFI Shariah Standard No. 21 still apply in full.

Does National Grid pass the business activity test?

The activity screen is only part of the picture this month: National Grid currently fails the interest-bearing debt screen, so the overall verdict is not compliant regardless of the business itself. The watch item in this sector is the sharpest of all: revenue must come from permissible services, not from lending at interest.

Is National Grid's income Halal?

Yes, within AAOIFI's tolerance. National Grid's income from non-permissible sources stays below 5% of revenue in the September 2026 screening.

Does National Grid meet AAOIFI's debt and investment ratio requirements?

Not in full. Interest bearing debt currently exceeds the 30% cap, while the other ratio stays within it. One breach is enough to fail the screening; the ratios are reassessed monthly under our Shariah Supervisory Board.
