The verdict in three sentences
For a plumbing company in London, local SEO produces leads at 12-35 EUR, two to four times cheaper than lead-matching platforms (45-80 EUR per lead, often shared). The realistic monthly budget runs from 400 to 1,000 EUR and drives +60% calls in five months. The key difference: an SEO lead is exclusive and yours, whereas a platform lead is resold to 3 or 4 competitors at once.
The foundation: pages by service and by area
A tradesperson chasing callouts must cover every intent: "leak repair London", "water heater London", "drain unblocking London", plus surrounding areas (Camden, Islington, Hackney). Each service + area combination becomes a page.
| Page type | Sample query | Estimated volume/month |
|---|---|---|
| Emergency service | leak repair London | 300-600 |
| Equipment service | water heater installation London | 150-300 |
| Service + area | plumber Camden | 80-200 |
| Renovation | bathroom renovation London | 200-400 |
| Maintenance contract | boiler servicing London | 100-250 |
Emergency queries convert best: the customer calls within the hour.
SEO vs lead platforms: the real cost per inquiry
Lead platforms appeal through their simplicity, but their business model penalizes the tradesperson over time.
| Criterion | Local SEO | Lead platform |
|---|---|---|
| Cost per lead 2026 | 12-35 EUR | 45-80 EUR |
| Lead exclusivity | Yes | No (shared) |
| Monthly budget | 400-1,000 EUR | Variable, no cap |
| Conversion rate | 25-40% | 8-18% |
| Asset owned | Site + reviews | None |
| Effect when stopped | Persists | Stops dead |

Are Google reviews decisive for a plumber?
Yes, they are the top trust signal for callouts. Targeting 6 to 10 new reviews per month above a 4.5 rating clearly improves local ranking and call rate.
How many pages should I create?
Between 10 and 20 service + area pages to cover London and its boroughs. Fewer well-crafted pages beat thirty empty ones.
Does SEO work for emergencies?
Yes, especially via the Google Profile and local pack, which top mobile results. That is where most callout calls are won.
Can I drop lead platforms entirely?
Gradually. Keep platforms early for flow, then reduce as SEO ramps, usually after 4-6 months.
What minimum budget for a solo tradesperson?
From 400 EUR/month to cover one city and 2-3 nearby areas. A 700 EUR/month budget lets you target an entire metro area.
