High yields look tempting. But do the biggest payers actually reward you? To find out, I took the 10 highest yielding UK dividend shares in the FTSE 100 a year ago and imagined putting £1,000 into each one.
No hindsight and no cherry picking. Here’s exactly what happened to that £10,000.
How the 10 UK Dividend Shares Were Picked
The rule was simple. I took every company in the FTSE 100 on 27 October 2025 and ranked them by their dividend yield over the previous 12 months. The top 10 made the cut.
Each share got £1,000 at the closing price that day. I then tracked the share price and every dividend until the close on 23 October 2026.
To keep it simple, dealing costs and stamp duty are left out. Dividends were taken as cash, not reinvested, and counted by their ex dividend date.
The 10 Highest Yielding UK Dividend Shares in October 2025
| Company | Yield on 27 Oct 2025 |
|---|---|
| Legal & General | 8.8% |
| WPP | 8.8% |
| Standard Life (then called Phoenix Group) | 8.0% |
| M&G | 7.6% |
| Admiral | 7.2% |
| Mondi | 7.1% |
| LondonMetric Property | 6.3% |
| Imperial Brands | 6.3% |
| British American Tobacco | 6.1% |
| BP | 5.6% |
That’s a lot of insurers, two tobacco companies and an oil major. In other words, classic UK income territory.
What £10,000 in UK Dividend Shares Turned Into After One Year
Here’s how each £1,000 did, ranked from best to worst.
| Company | Share price change | Dividends received | Total value | Total return |
|---|---|---|---|---|
| BP | up 46.4% | £57.47 | £1,521.92 | up 52.2% |
| Standard Life | up 33.6% | £82.14 | £1,418.16 | up 41.8% |
| Legal & General | up 22.7% | £89.91 | £1,316.83 | up 31.7% |
| M&G | up 17.3% | £77.39 | £1,250.57 | up 25.1% |
| Admiral | up 16.7% | £48.64 | £1,215.31 | up 21.5% |
| British American Tobacco | up 13.3% | £62.35 | £1,195.56 | up 19.6% |
| WPP | up 9.9% | £41.39 | £1,140.73 | up 14.1% |
| Imperial Brands | down 4.8% | £54.42 | £1,006.17 | up 0.6% |
| LondonMetric Property | down 7.1% | £64.69 | £994.07 | down 0.6% |
| Mondi | down 12.2% | £14.59 | £892.92 | down 10.7% |
| Total | up 13.6% | £592.97 | £11,952 | up 19.5% |
So the £10,000 grew to roughly £11,952. That’s a 19.5% total return, with almost £593 of it paid out as cash dividends.
Did These UK Dividend Shares Beat the FTSE 100?
Yes, comfortably. Over the same dates, £10,000 in the iShares Core FTSE 100 ETF would have grown to about £11,399, including its dividends. That’s a 14.0% total return.
The 10 high yielders were around £553 ahead. They also paid out far more cash along the way, at £593 against roughly £337 from the tracker.
However, one year is a very short test. A tracker fund still makes a lot of sense for most people, and I’ve explained why in how to build a simple index fund portfolio in the UK.
The Winners: BP, Standard Life and Legal & General
BP was the standout, up 46% on the share price alone. Oil prices jumped in the year to October 2026, and energy shares came along for the ride.
Meanwhile, Standard Life and Legal & General did exactly what income investors hope for. Both paid big, steady dividends and both share prices rose strongly too. Legal & General paid out almost £90 on a £1,000 stake.
The Losers: Where High Yields Went Wrong
Mondi is the warning sign. It looked like a 7.1% yield in October 2025. Then in February 2026, it cut its final dividend from 46.67 to 4.92 euro cents. The shares fell 12% and only paid out £14.59 over the year.
WPP tells a similar story. Its 8.8% yield was based on dividends it had already started cutting. So £1,000 only collected £41.39, less than half what the headline yield suggested.
Imperial Brands and LondonMetric paid their dividends as normal. However, falling share prices wiped out the income, so both roughly broke even.
What These UK Dividend Shares Teach Us About Investing
Lesson 1: A High Yield Can Be a Warning
When a yield looks unusually high, the market is often expecting a cut. Mondi and WPP both proved that in the year to October 2026. Check whether a dividend is actually covered by profits before trusting the number.

Lesson 2: Dividend Growth Matters More Than Yield
The best performers paid dividends that held up or grew. That’s the whole idea behind my approach to dividend growth investing in the UK.
Lesson 3: Spreading Your Money Protects You
One share lost 10.7%, yet the portfolio still made 19.5%. Ten shares across different sectors meant no single mistake could sink the lot.
Lesson 4: Use an ISA for Dividend Income
Outside an ISA, you only get a £500 dividend allowance before tax kicks in, according to GOV.UK. Inside a stocks and shares ISA, every penny of that £593 would be tax free. If you’re unsure which wrapper suits you, read my guide to the different types of ISA.
Should You Put a Lump Sum Into UK Dividend Shares?
In the year to October 2026, high yield UK dividend shares paid off. Next year could look completely different, and a single year proves very little.
If you’ve got a lump sum to invest, start with the basics. My guide on what to do with a lump sum in the UK walks through emergency funds, pensions and ISAs first.

Disclosure: I hold Legal & General, Standard Life and BP in my own ISA. I don’t hold any of the other seven shares in this post.
This post is for education only and isn’t financial advice or a recommendation to buy any investment. Figures use closing prices from 27 October 2025 and 23 October 2026, ignore dealing costs and stamp duty, and count dividends by ex dividend date. Share prices can fall as well as rise, dividends can be cut, and past performance is no guide to future returns.
