Plumbing & heating

Websites for plumbers, built around the emergency call.

Somebody standing in two inches of water is not reading your about page. They are on a phone, they have opened four tabs, and they are ringing whichever one makes it easiest. That is the whole design brief.

The actual problem

Two completely different customers, one website.

A plumbing site has to serve two people who want opposite things.

The first has a burst pipe. They want a phone number in under three seconds, confirmation you cover their postcode, and some sign you will answer at nine on a Sunday night. They will not scroll. If they have to hunt, they are gone.

The second is planning a bathroom or replacing a boiler in six weeks. They want to see previous installs, understand roughly what it costs, check your Gas Safe registration, and read something that sounds like a person.

Most plumbing websites are built for the second customer and lose the first one entirely. We build for both, with the emergency route taking priority on mobile because that is where those visits come from.

What goes on a plumber’s site

The emergency path comes first.

Every item here maps to a decision someone makes in the first few seconds. Get those right and the rest of the site has time to do its job.

One-tap calling, always visible

A sticky call button on mobile that follows the visitor down the page. No hunting through a contact page while the ceiling drips.

Gas Safe registration displayed

Your registration number shown clearly, because it is a legal requirement for gas work and the first thing a careful customer checks. WaterSafe, CIPHE and OFTEC credentials get the same treatment.

Coverage that is unambiguous

A plain statement of the postcodes and towns you cover, plus your genuine callout hours. Vague coverage claims cost you calls from people who assume they are outside the area.

Emergency and planned, split cleanly

Separate routes through the site for a burst pipe and a bathroom refit. They need different information and different urgency.

Boiler and installation work

The brands you install and service, warranty terms, and finance if you offer it. Boiler replacement is a considered purchase and the detail is what wins it.

Landlord and commercial work

Gas safety certificates, landlord compliance and maintenance contracts are steadier income than domestic callouts. They deserve their own page rather than a bullet point.

Why plumbing specifically

We have done this trade before.

Before starting Swift Web Design, Josh worked at a marketing agency handling a strange spread of clients: paint sprayers, decorators, a couple of charities, plumbers, and at one point a private jet company. The plumbing work is where the pattern above came from.

The same mistakes came up every time. The phone number was an image so it could not be tapped. The Gas Safe number was missing. The site took eight seconds to load on 4G, which is exactly the connection an emergency customer is using.

Crestline Trades is our multi-trade demo covering electricians, plumbers and builders, built to show the layout without a client’s branding on it. See the demo →

Common questions

What plumbers usually ask

Yes, and it should be prominent rather than tucked in a footer. Gas Safe registration is a legal requirement for gas work in the UK and it is the single credential a cautious customer checks before ringing. We put the number where it is visible on the pages that matter, and can link it to the official register.

That is the part we design first. On mobile the phone number becomes a sticky tap-to-call button that stays on screen as the visitor scrolls, with your callout hours and coverage area stated near it. Emergency visitors do not scroll and do not fill in forms, so the call has to be one tap from wherever they land.

Usually a callout fee and some honest ranges, rather than a full price list. Plumbing jobs vary too much to quote blind, but a customer with no figures at all often assumes the worst and rings someone who gave them a number. A stated callout charge and a rough band for common jobs tends to increase calls rather than reduce them.

Worth its own page. Gas safety certificates, landlord compliance and maintenance contracts are more predictable income than domestic emergencies, and the people searching for them use completely different terms. Treating it as one bullet on a services page means missing that search traffic entirely.

Fast, and this matters more for your trade than most. Emergency customers are on mobile data, often indoors, sometimes in a panic. We build lean pages with compressed images and no heavy page builder bloat, because a site that takes eight seconds on 4G has already lost the call.
