Marketing for plumbers: what brings in work for a UK plumbing and heating firm

Marketing for plumbers comes down to being the firm a homeowner can find, check and trust in the minute before they ring. For most UK plumbing and heating firms that means three things first: a Google Business Profile with reviews arriving steadily, a website that shows your Gas Safe number and the work you want, and being found for that work in your own towns. Then the things only a plumber has: landlords who need you every year, boiler customers due a service, and a van that is in the street when the next pipe goes.

We build websites and do SEO for trades, so we have an interest in the first three. The rest of this guide covers what we do not sell, with the rules taken from their sources and the search figures dated.

When people look for a plumber, month by month

Plumbing work does not arrive evenly, and the search data shows by how much. These are UK Google Ads figures for the twelve months to September 2026, or to August 2026 for power flush and plumber near me, where Google's latest month is August (DataForSEO, read 10 November 2026; Google rounds them into bands):

Search	Quietest month	Busiest month
boiler service	8,100 (May 2026)	27,100 (October 2025)
boiler repair near me	2,900 (June to August 2026)	14,800 (October 2025)
new boiler	4,400 (July 2026)	14,800 (November 2025 and January 2026)
power flush	880 (June to August 2026)	3,600 (September 2025 and January 2026)
frozen pipes	480 (June 2026)	3,600 (January 2026)
blocked drain	3,600 (July to September 2026)	6,600 (October and November 2025, January and March 2026)
bathroom fitters near me	3,600 (December 2025)	9,900 (October 2025 and January 2026)
gas safety certificate	8,100	12,100
plumber near me	74,000	110,000

Three patterns matter for marketing. Heating work runs from September to January and falls away by summer. Bathrooms dip before Christmas and come back hard in January, when people plan the year's work. And the everyday searches, "plumber near me" and gas safety certificates, never drop very far: that is the steady base under the seasonal peaks.

So most of the marketing that takes time, pages, reviews and a profile that ranks, has to be done in the summer, ready for people who start searching in September.

Start with what a homeowner checks

Someone with water coming through the ceiling, or a landlord whose tenant has no heating, picks quickly. What they see in that minute decides who gets the call.

• A complete Google Business Profile. Google says local results are "mainly based on relevance, distance and popularity", and that "more reviews and positive ratings can help your business's local ranking". Set Plumber as the primary category with Heating contractor where it applies, list the jobs you do, set the service area to the towns you actually cover and keep the hours true. If your profile is not appearing at all, our guide on a Google Business Profile not showing finds the cause.
• Reviews after every job. A plumber finishes several jobs a week, so the chances to ask come round constantly. Ask every customer the same way, on the day: Google's policy bans offering anything in exchange for a review and asking only the happy ones, and since 6 April 2025 UK law bans fake reviews and reviews that hide an incentive. Our guide on how to get Google reviews has the wording, and the free Google review QR code generator makes a card to leave behind.
• A website that answers the questions. Your Gas Safe number, the towns you cover, whether you do emergency call-outs and when, the boilers you fit, and a phone number that works one-handed. Our page on websites for plumbers shows how we build them.

Be found for the work you want

The searches worth winning name the job. Someone typing "boiler installation" plus their town has accepted the spend and is choosing who does it; someone typing "plumber near me" may want a tap washer. To be found for the work you want more of, you need a page for each kind of job, boiler installation, boiler repair and servicing, emergency call-outs, landlord certificates, bathrooms, with your own photos and the towns you genuinely cover, and a profile whose services match.

That ongoing work is what plumber SEO is. It is slower than buying a lead and it keeps working after a subscription would have stopped. What it costs a month is in our guide to how much SEO costs.

Gas Safe, WaterSafe and the badges homeowners check

Plumbing is one of the few trades where the badge is the law. In Great Britain, the Gas Safety (Installation and Use) Regulations 1998 say no self-employed person may carry out gas work unless they belong to the class of persons approved by the Health and Safety Executive, and HSE's own guidance says anyone working on gas appliances in a home must be a Gas Safe registered engineer. The same regulations make it an offence to falsely pretend to be registered.

That makes your Gas Safe number marketing in its own right. HSE tells householders that an engineer's competencies are on the back of their Gas Safe Register ID card and that they can ring Gas Safe Register or check its website. A homeowner who has been told to check will look for the number, so put it on the profile, on every page that mentions gas work, on the quote and on the van.

WaterSafe is the equivalent for water. Its register describes itself as "a free online directory and national accreditation body for competent and qualified plumbers". Approved contractors can carry out certain work without notifying the water supplier first and issue Certificates of Compliance. If you are approved, you are also listed in a search that homeowners use to find a plumber, at no cost per enquiry.

Trade bodies such as CIPHE and APHC are worth naming where you belong to them, linked to the body's own site so a customer can check. Checkatrade, MyBuilder and the other directories are a different thing, a paid listing rather than a qualification, compared with dated prices in our Checkatrade alternatives guide.

Landlords and letting agents: the work that comes back every year

Landlord gas safety work is the most predictable marketing a plumber has, because the law sets the date. In Great Britain a landlord must have each gas appliance and flue in a let property checked "at intervals of not more than 12 months", and a check made in the two months before the deadline counts as made on the deadline, so the next one keeps the same date.

That turns every landlord you work for into a booking a year, often across several properties. Three habits turn it into a steady flow:

1. Keep a list of every landlord property you check, with the date it is next due.
2. Send the reminder about two months before the deadline, which is inside the window where an early check still keeps the same date.
3. Ask letting agents in your towns who does their gas checks now. An agent with fifty properties is fifty bookings a year, every year.

The same thinking works for homeowners. HSE advises that gas appliances are serviced at least once a year, so every boiler you fit or service is a reminder to send next year, in the summer, before the autumn rush fills the diary.

The van, the cards and the street

The van. In England, the government's guide for advertisers lists adverts on a vehicle that is normally moving among those outside the planning authority's direct control, so the van can carry your name, number, web address and Gas Safe number, as long as it is used as a van and not parked up as a billboard. The rest of the UK has its own rules.

Cards and leaflets. A card left after every job, with your number and a QR code for a review, does two jobs at once. A leaflet through the doors on the street where you have just worked reaches people who saw the van for a week.

Other trades. Builders, kitchen fitters, electricians and bathroom showrooms are all asked "do you know a good plumber?". Pass work their way and ask them to do the same.

Paying for adverts and leads

When the diary has a gap next month, paid channels are the quick fix, and every one of them is buying the same searches. Advertisers pay around £17.36 a click for "emergency plumber", £14.64 for "boiler installation", £8.46 for "boiler repair" and £6.05 for "plumber near me" (DataForSEO, November 2026, converted from US dollars). Google's Local Services Ads charge per lead instead of per click; our guide to Local Services Ads for UK trades explains how that price is set.

Lead sellers are the same advertising with a margin on top. Get Work, for example, spends half of each monthly fee on Google Ads, from £300 of a £600 plan plus VAT (read 10 November 2026). What the other sellers charge, and how to judge a lead on cost per booked job, is in our guide to plumbing leads. Use paid channels to fill gaps, not as the plan, and cut them back as your own enquiries grow.

A marketing plan for a plumbing year

When	What to do
Spring	Ask for a review after every job; build or update the bathroom pages, since "bathroom fitters near me" held at 8,100 a month from June to September 2026
June to August	Build the boiler repair, servicing and installation pages so they are live before September; send service reminders to last year's boiler customers
September to October	Profile hours and photos up to date for the rush; every emergency and boiler job ends with a review request
November to January	Answer the phone: "frozen pipes" searches peaked in January 2026 and "bathroom fitters near me" went from 3,600 in December 2025 to 9,900 in January 2026
Every month	Landlord reminders two months before each gas safety check is due

Track where every job comes from

Ask every enquiry how they found you, write it down, and once a quarter divide what each channel cost by the jobs it won. It is the only way to know whether the van, the badge, the directory, the ads or the website is earning its keep. The free lead cost calculator does the sum for paid channels side by side.
