3 British dividend stocks to consider for passive income this summer

The idea of passive income is understandably attractive — who wouldn’t want to earn money while they sleep? Some popular options include dropshipping, selling courses, or short-term rentals. But is it really passive if it requires regular work and upkeep?

Investing in dividend shares is one of the most truly ‘passive’ ways of earning income, because the money literally rolls in without any effort required.

But surely there’s a catch? Well yes — if you pick the wrong stocks, the income dream can quickly turn to financial loss.

So how can investors avoid this trap? Let me walk you through the common errors dividend investors fall foul of — and name three stocks that tick the right boxes.

What to look for in dividend shares

Dividends are never guaranteed, so buying a stock just because of one metric, like yield, is risky. Fortunately, there are ways to get a better idea of how reliable a dividend-payer is.

Check these factors when screening for stocks:

• A long record of uninterrupted payments, ideally 10 years or more.
• Regular dividend increases (I look for average 3%+ annualised growth over 10 years).
• Manageable debt (debt-to-equity ratio should be below 1).
• Well-covered dividend (payout ratio below 100%, cash coverage at least 2 times).

Not many shares will tick every box. Still, this short list can help investors avoid the classic mistake of buying a stock purely because the yield looks huge.

3 UK dividend stocks to consider as summer starts

Three British dividend shares that stand out to me at present are Legal & General, National Grid (LSE: NG.), and GSK. They all operate in mature sectors and are familiar names to many UK investors.

Most importantly, they combine established businesses, broad market familiarity, and forecast yields that still look attractive for income-focused investors.

But what makes National Grid particularly appealing this summer?

Why National Grid stands out

National Grid is a defensive utility name with a yield typically around 3.5-4%: less flashy but fitting a steadier income profile.

The company posted record FY2025 results with operating profit up from £5.2bn to £5.7bn and underlying EPS up from 72p to 78p.

Capital investment was high at £11.6bn and it declared a total dividend of 48.49p, up 3.8%. Infrastructure upgrades are ongoing, which can be costly, but promise long-term revenue growth.

However, there’s political risk. Oddschecker reported on 15 May that Andy Burnham is backed 10/11 as favourite to be the next UK Prime Minister after Keir Starmer. That matters because he advocates for stronger public control of utilities, which could impact National Grid’s profits.

That doesn’t automatically make it unattractive, but is one example of why even the most ‘dependable’ dividend stocks deserve careful consideration.

Final thoughts

Not all dividend shares are created equal. High yields can be difficult to maintain and are more susceptible to cuts.

Lower-yielding stocks like National Grid are worth considering as a foundation for an income portfolio because they’re highly reliable with £18bn of distributable reserves covering five years of forecast dividends.
