If you run a small service business in the UK, you already know word of mouth is important. But how important? And what do the numbers actually say?
This is a collection of the most relevant word of mouth and referral marketing statistics for UK small businesses — with sources. Bookmark it, share it, or use it to make the case for investing in a proper referral programme.
How much do consumers trust word of mouth?
88%
of consumers trust recommendations from people they know
This is the highest trust rating of any marketing channel. More than online ads, social media, or even editorial content. When a friend says "use this plumber", people listen.
Source: Nielsen Trust in Advertising Study, 2021 (40,000+ consumers, 56 countries)
77%
more likely to buy when recommended by friends or family
Word of mouth doesn't just build awareness — it drives action. People who receive a personal recommendation are significantly more likely to follow through and buy.

20–50%
of purchasing decisions are primarily driven by word of mouth
McKinsey found that word of mouth is the primary factor behind one in five to one in two purchasing decisions. For high-trust services like trades, this figure is likely at the higher end.

How do UK homeowners find tradespeople?
70%
of UK homeowners hire a tradesperson recommended by someone they know
Seven out of ten homeowners go with a personal recommendation. This dwarfs every other channel — platforms, Google, social media, leaflets — all combined.
Source: Powered Now survey (1,000+ UK homeowners)
12%
of UK homeowners found tradespeople through platforms like Checkatrade
Platforms like Checkatrade, Rated People, and MyBuilder account for a surprisingly small share of how people actually find tradespeople. If you're paying for leads on these platforms, word of mouth is nearly six times more effective.

18%
of UK homeowners found tradespeople via Google search
Google is important for visibility, but it's still less than a fifth of how people find trades businesses. Personal recommendations are nearly four times more influential.

How valuable are referred customers?
16%
higher lifetime value for referred customers

less likely to churn
Referred customers are 18% less likely to leave — and this difference doesn't fade over time. They're genuinely more loyal from day one.

of new business comes from referrals

82%
of small business owners say referrals are their primary source of new business
The vast majority of small business owners already recognise that referrals drive their growth. The opportunity is in making it systematic rather than leaving it to chance.

Word of mouth vs online reviews
42%
of consumers trust online reviews as much as personal recommendations
Reviews matter — but less than half of people trust them as much as a personal recommendation. A five-star Google review is good. A friend saying "call this person" is better.
