A plumber's website is a lead-generating machine or it is a vanity exercise. The trade does not need brochure copy about "professional service since 1998" — it needs a quote-form-led page that ranks in the local pack, loads in under two seconds on a busy mobile, and routes a tappable phone number straight into the dispatch process.
What is different about plumber websites
Two things make plumber web design distinct from generic small-business web design. First, the search intent is overwhelmingly urgent and local — "plumber [postcode]", "emergency plumber near me", "boiler service [city]". The site needs to convert intent into a phone call or a quote-form submission inside ten seconds of the user arriving. Second, the local-pack ranking is the only ranking that matters — page-one organic for "plumber [city]" is dominated by directories that the small trade cannot displace, but the local-pack three-pack above the organic results is winnable on schema and GBP quality.
What we ship for a plumber
A single-page Launch-tier site (£499) with the tappable phone number visible above the fold on every viewport, a two-field quote form (postcode + brief description) as the secondary conversion path, four service descriptions written to match the actual phrases customers in your area search for, Trustpilot or Google reviews pulled in and fed into AggregateRating schema, a Google Maps embed showing your service area, the Plumber + LocalBusiness schema with the Gas Safe Register number in a structured propertyValue, and the standard hosting + SSL package.
The Yell.com / Checkatrade economics
Most UK plumbers we audit are paying somewhere between £100 and £250 a month on directory subscriptions for inbound leads that a properly-built website would deliver organically inside the first quarter. The maths is straightforward: the £499 build cost is recovered inside the first or second month's worth of cancelled directory fees, and every subsequent month of saved subscription is pure margin or reinvestment budget. We do not require the directory cancellation as part of the brief — many clients run both for one billing cycle to compare — but the pattern is consistent enough that we mention it explicitly at handover.
The schema choices that matter
Plumber-specific schema choices that lift local-pack ranking: the Plumber sub-type (not the generic LocalBusiness), the Gas Safe Register number as a propertyValue (Google cross-validates against Gas Safe), the areaServed array enumerating the postcode districts you cover (not a vague radius), the OpeningHoursSpecification declaring the actual emergency-availability hours, and the AggregateRating fed from a real review pipeline. Each individually is a small signal; together they compound into a noticeable trust differential against the typical thin-schema competitor in the local pack.
Pricing for a plumber website
Most plumbers land on the Launch tier at £499 — a single-page quote-form-led site that does the lead-generation job for a one-or-two-engineer operation. Multi-engineer operations or plumbing groups with multiple service lines (domestic plumbing, commercial plumbing, gas servicing, drainage) move to the Growth tier at £899 for separate landing pages per service. Pro tier at £1,499 is for larger plumbing companies that want a content layer driving organic traffic on the longer-tail queries (boiler buying guides, comparison content, regulatory explainers).
