The market is dominated by small businesses. The vast majority of plumbing firms are sole traders or micro businesses with fewer than 5 employees. This means the competitive landscape is fragmented, with no single firm controlling a meaningful share of local markets.
That fragmentation is both an opportunity and a challenge. It means there is space for well-marketed businesses to dominate their local area, but it also means the barrier to entry is low, so competition is constant.
Business structure breakdown
| Business Size | Estimated Share | Typical Turnover |
|---|---|---|
| Sole trader (1 person) | 55 – 65% | £30,000 – £70,000 |
| Micro (2-4 people) | 25 – 30% | £100,000 – £400,000 |
| Small (5-10 people) | 5 – 10% | £400,000 – £800,000 |
| Medium+ (10+ people) | 2 – 5% | £800,000+ |
Average job values
Understanding what each type of job is worth helps you work out which services to target in your marketing and how much you can afford to spend acquiring each customer.
| Job Type | Average Value | Notes |
|---|---|---|
| Emergency call-out | £120 – £250 | Call-out fee (£60-£120) plus first-hour labour |
| Standard repair | £100 – £300 | Tap replacement, toilet repair, leak fix |
| Boiler service | £70 – £120 | Annual service, lower margin but recurring |
| Boiler installation | £1,500 – £3,500 | Highest-value common job |
| Full central heating system | £4,000 – £8,000 | Major project, often via referral or SEO |
| Bathroom installation (labour only) | £1,500 – £3,500 | Multi-day job, good margin |
| Full bathroom (labour + materials) | £2,500 – £6,000 | Higher value when supplying materials |
Hourly and day rates
| Rate Type | National Average | London / South East |
|---|---|---|
| Hourly rate | £45 – £75 | £65 – £105 |
| Day rate | £250 – £500 | £400 – £700 |
| Emergency call-out fee | £60 – £120 | £80 – £150 |
The key insight for marketing: boiler installations and bathroom work generate the highest revenue per job, so they justify the highest marketing spend per lead. Emergency work converts quickly but at lower total value. The smartest plumbers run separate marketing campaigns for each service type, with different cost-per-lead targets.
How customers find plumbers
How customers choose a plumber has shifted dramatically in the last five years. Word of mouth is still important, but it is no longer the dominant channel for new customer acquisition.
| Channel | Estimated Share of New Leads | Trend |
|---|---|---|
| Google Search (organic + ads) | 35 – 45% | Growing, especially “near me” searches |
| Word of mouth / referral | 20 – 30% | Stable but declining as a share |
| Trade platforms (Checkatrade, MyBuilder) | 15 – 20% | Growing, but margins thinning |
| Google Business Profile (map pack) | 10 – 15% | Growing fast, especially mobile |
| Social media | 3 – 5% | Growing slowly for trades |
| Other (directories, print, leaflets) | 5 – 10% | Declining |
The most significant shift is the dominance of Google. When you combine paid ads, organic search results, Google Business Profile listings, and Google Local Services Ads, Google accounts for roughly half of all new customer enquiries for plumbers in urban and suburban areas.
Word of mouth remains important, but it is increasingly mediated through online reviews. A customer may be “referred” by a friend, but they will still check your Google reviews before calling.
Search demand and keywords
Search demand for plumbing services is high and consistent throughout the year, with seasonal spikes during winter months when boiler breakdowns and frozen pipe emergencies increase.
Top search terms by volume
| Keyword | Estimated Monthly Searches (UK) | Intent |
|---|---|---|
| plumber near me | 90,000 – 120,000 | High intent, immediate need |
| emergency plumber | 40,000 – 60,000 | Urgent, highest conversion |
| plumber [city name] | 5,000 – 20,000 per city | Local intent |
| boiler installation | 25,000 – 35,000 | High value, planned purchase |
| boiler repair | 20,000 – 30,000 | Urgent-ish, good conversion |
| gas engineer near me | 15,000 – 25,000 | Specific, high-value work |
| bathroom plumber | 5,000 – 10,000 | Project-based, higher value |
The seasonal pattern is important for budgeting. Search volume for emergency plumber terms increases by 40 to 60% between October and February. Smart plumbers increase their Google Ads budget during winter and reduce it during summer, when demand drops but competition stays constant.
Customer acquisition costs
What it actually costs to win a new customer depends on the channel, the type of job, and your conversion rate.
| Channel | Cost Per Lead | Typical Close Rate | Cost Per Customer |
|---|---|---|---|
| Google Local Services Ads | £15 – £40 | 50 – 60% | £25 – £80 |
| Google Search Ads | £20 – £60 | 30 – 40% | £50 – £150 |
| SEO (organic) | £10 – £25 (amortised) | 40 – 50% | £20 – £60 |
| Checkatrade | £15 – £40 | 30 – 50% | £30 – £130 |
| MyBuilder | £10 – £35 (per shortlist) | 20 – 30% | £35 – £175 |
| Word of mouth | Free | 60 – 80% | Free |
The key metric is not cost per lead but cost per acquired customer relative to the job value. If a boiler installation is worth £2,500 and it costs you £80 to acquire that customer through Google Ads, that is a 31:1 return. If a standard repair is worth £150 and costs £80 to acquire, that is barely worth doing through paid channels.
This is why the most profitable plumbers segment their marketing by service type: paid ads for high-value jobs (boilers, bathrooms, central heating), SEO and Google Business Profile for emergency and standard work, and platforms for early-stage credibility building.
Red flags and common mistakes
Mistake 1: Treating all leads the same
A boiler installation lead is worth 10 to 20 times more than a dripping tap lead. Your marketing budget should reflect this. Run separate campaigns with separate budgets for high-value vs. standard work.
Mistake 2: No online reviews strategy
Plumbers with 50+ Google reviews and a 4.7+ rating get significantly more enquiries than those with fewer than 10 reviews. Yet most plumbers never ask for reviews. Set up an automated review request that goes out after every job.
Mistake 3: Ignoring seasonal patterns
Search demand for emergency plumbing jumps 40 to 60% in winter. If your ad budget stays flat year-round, you are under-spending when demand is highest and over-spending when demand drops.
Mistake 4: Relying on a single channel
Plumbers who depend entirely on Checkatrade, or entirely on word of mouth, or entirely on Google Ads are one algorithm change or price increase away from a quiet month. Spread your marketing across at least three channels.
Mistake 5: No website in 2026
Around 30% of sole trader plumbers still have no website. Even a basic 5-page site with your services, service area, contact details, and reviews gives you credibility that a Checkatrade profile alone cannot match.
