What a plumber's website needs

Start with how customers choose a plumber

A website is easier to plan when you picture the person using it. For plumbing, that person is usually in one of two situations. Either something has gone wrong and they need help soon, or they are planning a job, such as a new bathroom or boiler, and are comparing firms over a few days.

Both want to know the same basic things: can you do the job, do you work where they live, can they trust you, and how do they get in touch. The urgent customer wants those answers in seconds. The planning customer wants more detail and more proof. A good site serves both without making either wade through the other's content.

Most of them will be on a phone. Ofcom's Online Nation 2025 report found smartphones account for the majority of UK adults' time online.^[1][2] So when this guide talks about what the website "shows", picture a phone screen first.

1. A phone number that dials in one tap

This is the most important element on the site. Put the number in the header of every page, make it a tap-to-call link on phones, and write the digits out in full so people can also copy or type them. Label it plainly, for example "Call 01632 960123", rather than relying on a small phone icon.

Pick a number customers feel safe calling. A local number or a mobile is familiar. An 03 number also works: Ofcom says calls to 03 numbers cost no more than a national-rate call to an 01 or 02 number and count towards inclusive minutes.^[3] Avoid premium-rate numbers. Google does not accept them on a Business Profile at all.^[4]

If you cannot answer while working, say so near the number, with when you return calls. A short line such as "On a job? Leave a message and I will call back the same day" turns a missed call into a waiting customer instead of a lost one.

2. The jobs you do, in customers' words

List your services the way customers describe their problems. People search for "boiler not working", "leaking pipe under sink" or "new bathroom fitted", not for trade categories. Each main service deserves its own page with:

• What the job involves, in a few short paragraphs.
• What is and is not included.
• Roughly how long it takes and what the customer needs to do, such as clearing access to the stopcock.
• How you price it: fixed price, hourly, or quote after a visit.
• Any registration that applies, such as Gas Safe for gas work.

Be selective. If you do not want small repair jobs, do not list them. A website that brings in the wrong work costs time on the phone.

3. The areas you cover, precisely

"We cover the whole region" tells a customer nothing. List the towns and postcode districts you serve. If emergency cover is smaller, list that separately. If there are places you never go, it is fine to say so.

For towns where you do a lot of work and have something specific to say, a dedicated area page can help customers and search engines. Keep them genuine: Google's spam policies class pages targeting many cities that funnel users to one page as doorway abuse.^[5] Our service area pages explain how to make them useful.

4. Credentials a customer can check

Registrations are among the strongest trust signals a plumbing firm has, because they are checkable. Show them with numbers and links, not just logos.

Sources: HSE on Gas Safe checks,^[6] WaterSafe on approved contractors^[7] and the CIPHE.^[8] Only display a logo if you are authorised to. Trading Standards guidance warns businesses to take care when membership lapses or is cancelled, and not to use a logo without authorisation.^[9] The Gas Safe guide goes into detail.

5. Evidence from real customers

Reviews and photos of your own work do more than any amount of descriptive copy. Show a selection of genuine reviews and link to where they were posted so customers can see the full picture. Do not cherry-pick: since 6 April 2025 the DMCC Act has banned fake reviews and the misleading presentation of reviews, including suppressing negative ones.^[10] Our reviews guide explains what that means in practice.

Photos should be yours: finished jobs, your van, your team. Phone photos are fine if they are sharp and well lit. Stock images of models in clean overalls tell the customer nothing about you.

The next layer: details that settle doubts

Once the five essentials are in place, these additions answer the questions that stop people calling.

• Pricing basis. Call-out fees, hourly rates or how quotes work. You do not need a full price list, but customers like to know what to expect.
• Who will turn up. A short about page with names and photos, if your team is comfortable with it.
• Hours and response. When you work, when you answer and how quickly you reply to forms.
• What happens next. A simple description of what follows a call or form: a callback, a visit, a written quote.
• Common questions. The things you are asked on the phone every week, answered once on the site.

Policies and small print

Every business website that collects personal data needs a privacy notice. If customers send you their name, phone number and address through a form, the ICO says they must be told why the data is collected, how long it is kept and who it is shared with, at the time it is collected, in clear and plain language.^[11] If you take bookings or payments online, you will also need terms that explain cancellations and rights. An accessibility statement is good practice and shows you have thought about customers with different needs. See the enquiry forms guide for the detail.

What you can safely leave out

Plenty of things appear on trade websites because a template included them, not because they help. Automatic chat pop-ups, image sliders, long histories of the company, mission statements, counters claiming thousands of happy customers and pages of generic tips copied from elsewhere can all go. Each one adds weight to the page and distance between the visitor and your phone number.

A blog is optional. A few well-written guides that answer real customer questions can help, but an abandoned blog with three posts from years ago does more harm than none.

Putting it in order

If you are building or fixing a site on a tight budget, work in this order: phone number and contact routes, services, areas, credentials, reviews and photos, then pricing basis, about page and policies. Each step on that list makes the next one more effective. The feature checklist lists every item in more detail, and the brief builder turns your answers into a brief you can hand to any designer.
