What matters now
- The model range is unusually wide (£4.52 to £13.72). The outcome hinges heavily on assumptions, so read the point estimate with caution.
- Solid but not exceptional quality (54/100) and above fair value, neither a clear bargain nor a standout compounder.

How to read this chart
60‑month range £6.80 – £14.36 · fair‑value band £4.52 – £13.72 · the £13.62 price screens above the £8.80 fair value. Green steps = our fair value per fiscal year (point-in-time, no hindsight). Dashed = 300-day average. As of Aug 23, 2026.
Analysis
United Utilities Group PLC (UU) currently trades at £13.62, while our model-based Fair Value estimate is £8.80, implying the stock looks roughly 54.8% overvalued today. The Quality Score stands at 54/100 (solid quality), in the Utilities sector. Bull case: the Growth Earnings group reads highest at a median of £11.34 per share, and 1 of the 14 models we run sit above the £13.62 price. Bear case: the Asset-Based group reads lowest at £2.02, and 13 of the 14 models stay below the price. Evidence for this calculation is high.
Over the trailing twelve months, United Utilities Group PLC generated revenue of £2.6B at a net margin of 22.4%. Revenue grew 22.9% year over year. It earns a return on equity of 27.7%. Net debt stands at £9.7B. Fundamentals as of Aug 23, 2026
Our scenario range runs from £4.52 (bear case) to £13.72 (bull case); at £13.62, the current price sits within that range. Bear and bull are the same models run on conservative and optimistic assumptions (margins, growth, valuation multiples), so a plausible valuation range, not a price target. For context, the median of 10 Utilities peers we cover trades at 12% fair-value upside, at −35%, UU screens richer than that median.
Fair Value models
This estimate rests on fiscal year 2026 figures, and about 5 months have passed since. In that time the company retained roughly £0.1398 per share, which is 1.6 % of the fair value. The fair value deliberately does not add this in: the models value reported figures, not a projection.
Each model estimates fair value its own way; the Fair Value above is the evidence-weighted, family-balanced blend. Evidence (0–100) measures how completely this model’s inputs are available: well-fed models carry more weight in the blend. The spread across models is intentional, each one stresses a different value driver; dividend models, for instance, come out structurally low when payout is small. Every input is real reported data, nothing guessed.
All 14 models by family
Widest divergence: Growth Earnings (£11.34) versus Economic Profit (£0.7300). Highest evidence: EPV (68).

Quality Score breakdown
Of which business quality 48 · Market factors (momentum, volatility) 69
Non-valuation factor families (profitability, growth, cashflow, financial strength, momentum …), each academically grounded. Valuation itself sits in the Fair Value and is deliberately excluded here to avoid double-counting.
All values are scores from 0 to 100 (100 = best against fixed, research-based bands), not percentages. The three market factors (momentum, 52-week proximity, low volatility) are displayed but carry zero weight in the headline number: market sentiment is not a business property.
