Where plumbing work comes from, and why call-outs and installs need different sources

Most advice about getting plumbing work treats it as one problem. It isn't. A burst pipe at eight on a Sunday night and a boiler swap booked three weeks out are different products, sold to different customers, won in different ways — and the sources that feed one are often poor at feeding the other.

So it's worth splitting the question. Here's where each half of the work comes from, and what it costs.

Emergency and repair work: won on speed

The customer has water coming through a ceiling. They are not comparing quotes; they're ringing down a list until somebody picks up. That changes what's worth paying for.

Google Business Profile. Free, and the single highest-value thing on this list for repair work. Someone searching "plumber near me" gets the map results and rings the top two or three. Recent reviews and a filled-in profile decide whether you're in that set. It costs time, not money.

Google Ads. This is the one trade where paid search genuinely earns its keep, because the intent is immediate — nobody idly searches for an emergency plumber. "Plumber near me" draws around 90,500 UK searches a month, with click costs reported at roughly £2.41–£13.98. The trap is that you pay per click whether or not the phone is answered. If you're under a floor with your phone in the van, you're buying clicks for someone else's benefit.

Home emergency and cover networks. British Gas, HomeServe and the rest run approved engineer networks that dispatch call-outs to policyholders. The work is steady and dispatched to you, but the rates are theirs. Joining terms vary by network and aren't generally published, so it's a conversation to have, not a price you can compare.

The shared platforms. They carry emergency work, but a platform that notifies three plumbers and waits for responses is structurally slower than a phone call. Fine for "my radiator's cold", weaker for water coming in.

Install work: won on the quote

Bathrooms, boiler swaps, heating upgrades. Bigger money, slower decisions, and the customer is genuinely comparing — usually three quotes.

The lead platforms. This is where they earn their money. Reported figures put everyday enquiries at £5–£35 on MyBuilder (you pay only when shortlisted), £15–£40 a lead on Rated People on top of a subscription of around £30–£60 a month, and Bark at roughly £1.80 a credit. Checkatrade is a different model again — a 12-month membership, cheapest listing £30 + VAT a month, lead plans quoted per trade and postcode. We've covered how the four compare and what Checkatrade actually costs in detail. Worth knowing: none of the price trackers publish plumbing-specific rates, so these are general trade figures.

Install networks. BOXT and similar operate closer to subcontracting than lead selling. You register as a Gas Safe engineer, set your availability, and get allocated jobs. They survey, quote and supply the boiler; you fit it. No lead fee at all — BOXT advertises up to £1,200 a day depending on the work, paid within about a week of sign-off.

That's a genuinely different trade-off, and worth being clear-eyed about. You're buying a filled diary and selling the customer relationship: no repeat work, no referrals, no reviews in your name, and their price rather than yours. As a way to fill quiet weeks it's strong. As your only channel it makes you a pair of hands with a van.

Merchants, showrooms and other trades. Kitchen and bathroom fitters, builders, electricians and letting agents all meet plumbing jobs they don't want. These convert better than anything you buy and cost nothing but turning up when you said you would.

The channel most plumbers never work

If you're Gas Safe registered, the most reliable work in this trade isn't sold by anyone.

Every landlord with a gas appliance must have an annual gas safety check by law, issued by a Gas Safe registered engineer. That's not a lead — it's a recurring obligation on a fixed clock. Bundled with a boiler service, reported pricing sits around £100–£140 a property a year.

The maths is the interesting part. A letting agent managing eighty properties is eighty appointments a year that you never have to buy again, spread across the calendar, with a payer who values one invoice and no diary management far more than they value your hourly rate. One agent relationship is worth more than a year of most subscriptions, and it doesn't evaporate when you stop paying a monthly fee.

It's neglected because it's unglamorous, it needs organising, and nobody advertises it to you. That's precisely why it's still available.

What each half actually costs you

The same lead fee reads completely differently across the two halves of the work.

On a call-out at £60–£120 including the first hour, a £25 lead is a real slice of the job — and it's only worth it if you convert almost all of them. Repair leads are cheap to buy and expensive to waste.

On a combi swap at £2,200–£3,200, or a bathroom at £4,000–£8,000, that same £25 is noise even if you win one in five. Install leads are worth buying wrong a few times.

Which produces two different disciplines. For repair work, the question is whether you can answer immediately — if you can't, don't buy the lead. For install work, the question is whether your quote arrives while they're still deciding, and whether it gives them something to choose you on beyond a number in a text message.

Both come back to the same weakness. Enquiries arrive as a missed call, a text, an app notification and an email from a platform, and on a busy week the £30 one you never answered looks exactly like the one that didn't exist. That's what grafter.ly is for on the ones that come in by email: forward it and it lands as a job in the same list as the rest of your work, ready to quote from your phone between calls.

Software is one way to fix that. A line in a diary is another, and it costs nothing. The thing that fails is carrying a fortnight of enquiries in your head and then judging the subscription on a feeling at renewal time.
