Most drainage firms buy leads before anyone can check who they are. This guide is about doing those two things in the right order.
The temptation is obvious. Drainage is emergency work, so leads feel like the tap that fills the diary, and the first marketing money goes to a directory, a lead reseller or an ads agency. But every paid lead lands on whatever the firm already looks like in public records. If those records disagree with each other, the money leaks. And now that AI assistants answer “who should unblock my drain”, the records are the marketing.
Everything in this guide is free. It is a weekend of fixes Whito calls the zero-pound weekend, and it comes before the first pound leaves the account.
Make your three records agree
There are three public records a customer, a directory or an AI engine can check in seconds: your Companies House record, your website, and your Google Business Profile. The fix is to make all three agree. Same trading name, same registered entity behind it, same address logic, same phone number, same trade description.
Most drainage firms fail this without knowing. The company was registered under a family surname in 2011. The website trades as “Rapid Drains”. The Google Business Profile says “Town Drainage Services” and carries a mobile number the website has never mentioned. Three names, one van.
A human customer might shrug. Software does not. Directories verify against Companies House. Google cross-checks its own listing against your site. An AI engine asked to recommend a firm assembles an answer from whatever public evidence stitches together into one confident identity. Three records that agree read as one established firm. Three records that disagree read as three flaky ones, and the engine names somebody else.
Making them agree costs nothing. Decide on one trading name. Put the registered company name and number in the website footer, on the contact page and in the Google Business Profile description. Use one phone number everywhere. If the trading name and the registered name differ, say so in one plain sentence: “Rapid Drains is the trading name of J. Bloggs Drainage Ltd, company number 01234567.” That sentence is written for both readers, the person and the machine.
The registers that belong on your homepage
Drainage has one register with legal force and two with proof value.
The Environment Agency waste carrier register is the legal one. If your business carries waste away, and a drainage firm tankering or bagging what comes out of a drain is carrying waste, you must be registered. Registration costs £191.02 unless you only ever transport waste you produced yourself, upper tier renewal is £130.25 every three years, and the fine for not registering is unlimited. Those figures are from gov.uk, read on 6 September 2026. Your registration number is checkable by anyone in the public register, so publish it on the homepage next to your company number. A firm that hides it looks like a firm that has not got one.
The trade bodies are proof, not law. The National Association of Drainage Contractors lists over 350 certified members and runs a member directory, at £400 a year (nadc.org.uk, read 6 September 2026). The Water Jetting Association sets the safety standard for jetting work, and in 2026 unified its codes of practice into the WJA Black Code; drain and sewer jetting sat under its Red Code before that (waterjetting.org.uk, read 6 September 2026). If your operatives are WJA trained or your firm is an NADC member, name it on the homepage and link the body. If not, do not invent a badge. Unverifiable logos are the fastest way to look like the national reseller you are trying not to be mistaken for.
Why the AI engine names a different firm in your town
Ask three AI assistants for a drainage firm in the same town and you can get three different names, none of them the firm with the most vans. This annoys owners, but the reason is useful: the engines are measuring your evidence, not your work.
An engine assembling an answer leans on what it can retrieve and reconcile: review platforms, directories, your site, public registers. A firm with a matched identity, a checkable waste carrier number, real reviews spread over years and a page that plainly says what it does and where, is easy to name with confidence. A better firm with a scrambled identity is a risk, and engines avoid risky answers.
Whito has not yet run its drainage engine study, so this guide will not pretend to know which platforms sit behind drainage answers in your town. What Whito has measured in neighbouring trades, in the UK AI Visibility Index and the electrician statistics hub, is that answers lean heavily on a small number of directory and review sources, and that the firms engines name are overwhelmingly the ones whose public records agree. The drainage study will publish on the Whito drainage hub first.
What you control today is the evidence: the three records, the registers, and a homepage a machine can parse. Which brings us to the test most firms fail.
The pricing page rule
Most UK trades publish no prices, and drainage is no exception. The result is that the only numbers a customer sees are the directories’. Checkatrade’s cost guide, updated June 2026 and read on 6 September 2026, tells the public an unblock averages £85, a call-out £60, an emergency call-out £180, jetting £185, and a CCTV survey £150 to £300. If you publish nothing, that page is your pricing page.
The rule: publish a range for any job you would happily quote over the phone, and say plainly why the rest is quoted after a look. For drainage that means publishing ranges for unblocking, jetting and CCTV surveys, because those are standard enough that you already quote them blind. Hold back excavation and repair prices, because they depend on what the camera finds, and say exactly that: “Repairs are quoted from the survey footage, so you only pay for what the camera proves.” A published range does three jobs. It beats the fear of the unknown call-out fee. It gives an AI engine a concrete fact to cite with your name attached. And it filters out the callers who were never going to pay a professional rate.
What to cut first
If money is already going out, cut in this order. First, per-lead resellers for emergency work, because a matched Google Business Profile catches the same 9pm search for nothing, and the reseller is often bidding on your town name against you. Second, the second and third directory subscriptions, because two directories listing the same firm add no new evidence, only new invoices. Keep the one that demonstrably sends jobs, and log which jobs for ninety days before renewing anything. Third, paid clicks on your own brand name, unless a competitor is actively bidding on it, which you can check by searching your own name in a private browser window.
The zero-pound weekend
The zero-pound weekend is Whito’s name for the two days of free fixes a firm does before it pays for a single lead. Nothing on this list costs money, and every item leaves public evidence a customer or an AI engine can check.
- Search your trading name plus your town in a private browser window. Note every version of your name, number and address that appears.
- Pick the one trading name. Write the “trading name of” sentence with your company number in it.
- Put that sentence, your waste carrier registration number and one phone number in the website footer.
- Claim or update the Google Business Profile: same name, same number, the drainage service category rather than plumber unless you do both, and the service area set to the towns you will drive to at night.
- Photograph the van, the jetter and the camera rig, and upload them to the profile. Real kit beats stock water.
- Write one plain paragraph on the homepage saying who you are, where you are, what you unblock, and that you are registered with the Environment Agency, in sentences a machine can lift whole.
- Publish ranges for unblocking, jetting and surveys, with a dated “prices checked” line.
- Text your last ten happy customers and ask for a Google review. Emergency customers are grateful and say yes.
- Check your NADC or WJA claims are current and linked, or remove them.
- Search “blocked drain” plus your town and read the AI answer if one appears. Write down who is named. That is your baseline, and it cost nothing.
When the zero-pound weekend is done, and only then, the paid channels have something worth landing on.
What this guide cannot measure
Without a live log of AI answers for drainage prompts, town by town and engine by engine, nobody can tell you which platforms drainage answers lean on, how often the named firms match Companies House records, or whether fixing your records moved you into an answer. Anyone who claims those numbers for drainage today is guessing. Whito’s drainage engine study will measure exactly that, on the method already published for electricians and roofers, and it lands on the drainage hub first. Until then, the free Whito Visibility Check will show you what the public records currently say about your firm, which is the part you can fix this weekend.
Questions owners ask
What is the zero-pound weekend?
The zero-pound weekend is Whito’s name for the two days of free fixes a business does before paying for any marketing: making the Companies House record, the website and the Google Business Profile agree, publishing the registers it holds, publishing price ranges for standard jobs, and asking recent customers for reviews. It costs nothing and it is the foundation every paid channel lands on.
Does a drainage company need a waste carrier registration?
If the business carries waste away as part of its work, yes. Registration with the Environment Agency costs £191.02 unless you only transport waste you produced yourself, upper tier renewal is £130.25 every three years, and the fine for operating unregistered is unlimited (gov.uk, read 6 September 2026). The registration number belongs on the homepage, because anyone can check it in the public register.
Should a drainage firm publish prices?
Publish a range for any job you would quote over the phone anyway: unblocking, jetting and CCTV surveys. Hold back repair and excavation prices, and say plainly that repairs are quoted from the survey footage. If you publish nothing, the only numbers a customer sees are the directories’ averages.
