AI Search for Plumbers in North Hertfordshire | Get More Emergency Call-Outs

Three weeks ago I sat in a cafe on Hitchin High Street with a plumber called Mike who's been working across North Hertfordshire since before I finished school. He pulled out his phone, opened ChatGPT, typed "who's the best plumber in Hitchin for a leaking radiator" and hit enter.

The answer came back with two names.

Neither of them was Mike.

He just stared at the screen for a bit. Then he said something I can't repeat here, and then he said "right, what do we do about this?"

The phone stops ringing and nobody knows why

Here's what's happening across the trades in this part of Hertfordshire. Plumbers, Gas Safe engineers, general heating blokes, they're all noticing the same pattern. Work was steady. Reviews were good. Google rankings hadn't budged. But the calls started thinning out around October, November last year.

Not dramatically at first. Just enough to notice.

The instinct is to blame the economy, or the time of year, or some new competitor undercutting on price. But that's not it. What's actually going on is that the way people find a plumber has quietly, properly shifted.

Your average homeowner in Letchworth with a dripping tap used to open Google, type "plumber Letchworth", scan through the results, read a couple of reviews, pick someone and call. That behaviour is disappearing. Not gone completely. But shrinking fast.

Now they open Perplexity or ChatGPT or just talk to Google's AI thing and say, in full sentences, "I've got a leak under my kitchen sink in Letchworth, it's been going since yesterday, who can come out today and roughly what will it cost?"

And they get an answer. One name, maybe two. Not a list. An answer.

What the AI is actually looking for when someone asks for a plumber

OK so this is where it gets interesting for anyone who actually wants to fix the problem.

I've run probably 200 test queries across different AI systems over the last few months. Plumbing-specific, North Hertfordshire-specific. "Emergency plumber Baldock." "Boiler repair Stevenage cost." "Who fixes combi boilers in Royston on a Sunday." That sort of thing.

The businesses that kept showing up shared a few things in common. And honestly, it wasn't always the ones with the fanciest websites or the most reviews.

It was the ones where the AI could find clear, specific, factual information about what they do.

That's it, really. But "clear, specific, factual" turns out to be surprisingly rare.

Your website is probably talking to nobody

I don't mean that to be rude. But I've looked at about 30 plumber websites across Hitchin, Stevenage, Letchworth, and the surrounding towns in the last six months, and nearly all of them have the same problem.

They say things like:

"We are a professional plumbing company offering a wide range of services across Hertfordshire."

Professional. Wide range. Across Hertfordshire.

What does that actually tell anyone? What does it tell an AI that's trying to answer the question "can someone fix my Worcester boiler in Baldock this evening?"

Nothing.

Compare it with something like: "We repair and service Worcester, Vaillant, Ideal, and Baxi boilers across Hitchin, Baldock, Stevenage, and Letchworth. Emergency callouts are £80 for the first hour. We aim to be with you within 90 minutes on weekday evenings."

That second version gives the AI something to work with. Specific brands. Specific towns. A price. A timeframe. The kind of information a real person actually wants when their heating's gone off and it's February in Hertfordshire.

The questions people are really asking

My wife always says I bang on about FAQs too much. She's probably right. But bloody hell, they matter.

(Bit of a tangent but bear with me.)

I asked a plumber near Royston to write down every question he got asked on the phone over two weeks. Not the technical stuff between him and other tradespeople. The questions from actual customers ringing up for help.

He came back with 23 questions. Things like:

• Do you charge a callout fee even if you can't fix it?
• Can you get parts for an old Baxi back boiler or do I need a whole new system?
• How quickly can you actually get here? (his most common question by far)
• Is it worth repairing my boiler or should I just replace it, honestly?
• What happens if the leak comes back after you've fixed it?

Not one of those appeared anywhere on his website. His FAQ page had four questions, three of which were about how long he'd been trading and whether he was Gas Safe registered.

We rewrote his site around those real questions. Gave each one a proper, detailed answer with specifics about cost, timing, process. Within six weeks, he started appearing in AI search results for queries about boiler repair in his area. Not every time. But enough that he noticed the phone picking up again.

Reviews aren't just for Google anymore

This is something I keep having to explain. When an AI decides who to recommend as a plumber in Stevenage, it doesn't just look at your website. It reads your Google reviews. Your Checkatrade profile. Your Trustpilot page if you have one. It cross-references all of it.

And it's not just counting stars.

It reads the actual words. A review that says "fixed our boiler in Hitchin same day, explained the issue clearly, charged exactly what he quoted" is worth far more to an AI than a review that says "great service 5 stars". Because the AI can pull specific details from that review and use them when forming a recommendation.

So when you ask customers for reviews (which you should be doing after every job, I know, I know, nobody likes asking), tell them it'd be really helpful if they mention what you did and where you were. "We had a leak fixed at our house in Baldock" is a hundred times more useful than "would recommend".

The Google Business Profile thing

Look, I've written about this before (there's a whole post on Google Business Profile and AI search if you want the detail) but the short version for plumbers is this:

Your Google Business Profile is probably half-finished.

You filled it in when you set it up. Name, address, phone number. Maybe a couple of photos from 2021. That's it.

But AI systems pull from your Business Profile constantly. Your service list, your opening hours, your Q&A section, your posts, your photos, all of it feeds into whether you get recommended or skipped over.

Go and check yours right now. Is every service listed individually? (Not just "plumbing" but "boiler repair", "emergency callouts", "radiator installation", "bathroom plumbing", each one separate.) Are your hours accurate, including emergency availability? Have you posted anything in the last three months?

A plumber I work with in Stevenage spent one afternoon sorting his Business Profile out properly. Added 14 individual services, updated his hours to show emergency availability, added photos from recent jobs, answered the questions sitting in his Q&A section. Three weeks later he got his first enquiry where the customer said they'd been recommended by an AI.

One afternoon.

The stuff you can't do in an afternoon

Right, there's also the bigger picture work. Restructuring your website content around questions people actually ask (not keywords from 2017). Implementing structured data markup so AI systems can properly parse what your site is about. Building consistent citations across local directories. Getting mentioned on local authority sites and community pages.

That takes more time. That's the kind of thing where working with someone who does this day in, day out starts to make sense. Not because you can't learn it, but because you've got pipes to fix and boilers to service and you probably don't want to spend your evenings reading about schema markup.

What happens if you do nothing

I had a bloke in Baldock say to me "Dan, I've survived 20 years without worrying about this stuff." And fair enough. Respect.

But the estate agents who used to recommend him? They're telling homebuyers to ask ChatGPT. The letting agencies who'd call him for maintenance work? They're using AI to find contractors. The word-of-mouth network that kept him busy... it's being replaced by a different kind of word-of-mouth, one that runs through algorithms instead of conversations at the school gate.

It's not happening overnight. But it is happening. Right now. Across Hitchin, Letchworth, Baldock, Stevenage, Royston, all of it.

The plumbers who sort their digital presence out for AI search in the next year will pick up the work that others are quietly losing. And the ones who sort it out first will have an advantage that compounds, because once AI systems start citing you regularly, that feeds into future recommendations.

If you're a plumber or heating engineer around here and you want to know where you stand, drop me a message. No hard sell, just an honest look at what the AI systems are saying about you right now.
