Electricians
Electricians have an advantage almost no other trade has: a large slice of their market is legally required to hire them on a schedule. Most never build a business around it.
How plumbers get customers: the work that repeats
Most plumbers are one bad month away from a quiet diary, and the reason is almost always the same: every job is a stranger. The fix is not more adverts, it is a handful of accounts that call you without searching.
Where the work actually comes from
Plumbing demand splits cleanly in two, and the halves behave nothing alike. Domestic emergency work — a burst pipe, a failed boiler in February — arrives through search, arrives in minutes, and is won by whoever answers the phone. Nobody in that state compares three quotes. They ring the first number that looks local and picks up, which is why response time beats price, reviews and every advert you could buy.
The other half is planned: bathroom fits, boiler swaps, landlord safety checks, commissioning on a new build. This work is scheduled weeks out, it is priced against competitors, and it is where the margin lives. It also almost never comes from a stranger. It comes from a letting agent with sixty flats, a facilities manager with four sites, a bathroom showroom that needs a fitter, or a builder who subcontracts the first fix.
That second half is a list of businesses, not a list of households. Every letting agent, care home and site manager in your county has a website, a phone number and a named person on the contact page. A plumber with six such accounts stops caring what the weather does to the emergency market, and that is the whole game.
The channels that produce work
- The Google Business Profile, treated as the shopfront it is. For emergency plumbing this is not one channel among many, it is the channel. Complete every field, add the service areas by name, and post photos of real jobs — a soldered joint, a clean reinstate, a tidy boiler cupboard. Reviews are the ranking lever you actually control: ask on the doorstep while the customer is relieved, not by text three days later when they have forgotten.
- Letting agents and property managers, approached directly. An agent managing sixty flats has a plumbing problem every week and a strong preference for one number that answers. They are not searching for you — they already have someone, and that someone is letting them down roughly a quarter of the time. The approach that works is specific: same-day response window, a fixed call-out rate, and a named contact. Email the agent, then follow up by phone; agents are on the phone all day and it is the medium they trust.
- Trade partners who sell the job but cannot fit it. Bathroom showrooms, kitchen studios, tile shops and estate agents all meet customers who need a plumber and have nobody to send them to. A showroom that recommends you on a bathroom sale hands you a fitted job at full price with no marketing cost. Walk in, leave a card, and price fairly on the first one — showrooms recommend the fitter who does not embarrass them.
- Landlord compliance work, which is legally recurring. Gas safety checks and legionella risk assessments are annual obligations, not discretionary spend. A landlord with eight properties is eight certificates a year, forever, and the renewal date is a calendar entry rather than a sales cycle. Portfolio landlords advertise themselves on letting agent sites and local landlord association listings.
The accounts worth approaching
Every trade on this site has a commercial customer base sitting behind the public one — businesses that buy repeatedly, book in advance and pay on account. They are also, conveniently, a list: each one has a website, a phone number and usually a named contact. These are the ones worth a deliberate approach.
| Who | Why they repeat |
|---|---|
| Letting agents and estate agencies | They hold the maintenance budget for hundreds of tenanted properties and need a plumber who answers on a Friday afternoon. One agent relationship is worth more than a year of leaflets. |
| Property management and block management firms | Communal systems, plant rooms and repeat call-outs across a whole portfolio, all booked by one facilities coordinator with a purchase order. |
| Care homes, nurseries and small hotels | They cannot close for a fault, so they pay for a response contract rather than a call-out, and they need documented compliance work every year. |
| Bathroom and kitchen showrooms | They sell the goods and subcontract the fit. A single showroom can feed a plumber several installs a month at retail rates. |
| Construction firms and general builders | First-fix and second-fix subcontracting on domestic extensions and small developments — bigger tickets, scheduled months ahead. |
Searches that build that list
Each of these is a business type run against the towns and cities you cover. One search per line, every location at once.
- letting agents — your city and every town within an hour
- property management companies — same radius
- care homes, nurseries, residential homes
- bathroom showrooms, kitchen studios, tile shops
- building contractors, property developers
What quietly empties the pipeline
- Chasing domestic emergencies only. It is the easiest work to find and the hardest to build on: no repeat, no referral, and a diary that empties every time the weather turns mild.
- Quoting commercial accounts at domestic rates because the volume flattered you. An agent with sixty flats will happily take your margin down to nothing if you let the first job set the price.
- Letting the phone go to voicemail. In emergency plumbing an unanswered call is not a lost lead, it is a lead delivered to the competitor two entries below you.
- Never asking the showroom, the builder or the agent for the next job. The single most profitable sentence in this trade is asked in person, at the end of a job that went well.
Questions
01 How do plumbers get commercial contracts?
By approaching the people who hold maintenance budgets rather than waiting to be found. Letting agents, block managers, facilities coordinators at care homes and schools, and small hotel owners all book plumbing repeatedly and all publish contact details. The pitch is not price, it is certainty: a response time you will commit to, a fixed call-out, an invoice they can process, and a named person who answers. Send a short email, follow up by phone within a week, and expect the third or fourth contact to be the one that lands — most agents are only interested at the exact moment their current plumber lets them down.
02 Is it worth paying for lead-generation sites?
As a stopgap, sometimes. As a business model, no. Paid lead platforms sell the same enquiry to several trades, so you are quoting against three others on price with no relationship, and the customer arrived through the platform rather than through you — meaning the repeat and the referral belong to them. They are a reasonable way to fill a slow month while you build direct accounts, and an expensive way to run a business permanently.
03 How many reviews does a plumber actually need?
Enough to look unremarkable rather than exceptional. Somebody in a genuine emergency is scanning for reasons to rule you out, not reasons to choose you: a profile with forty reviews at 4.7 converts about as well as one with two hundred, and both convert far better than eleven. Recency matters more than the total — a stream of reviews across the last few months reads as a working business, while a hundred reviews that all stop two years ago reads as a business that stopped.
04 What is the most underrated source of plumbing work?
Other plumbers. Every established plumber turns down work weekly — jobs too small, too far, outside their specialism, or on a week they are already full. A plumber who is known, reachable and reliably not a threat gets handed that overflow, and it arrives pre-qualified with the referral doing the selling. It costs nothing but the effort of being known to the ten or fifteen other plumbers working your patch.
Selling to plumbers instead?
Plumbers are one of the highest-yield markets a B2B seller can target. Nearly all of them are on Google Maps, most have a simple website with a contact address on it, and the sector buys constantly: job management software, van insurance, merchant accounts, parts suppliers, workwear, vehicle leasing, accounting and marketing services. Search plumbers across a set of cities and expect a strong email hit rate — this is exactly the profile the crawler handles best.

Other trades
HVAC contractors
This trade has a structural problem no amount of advertising solves: demand arrives in two spikes and disappears in between. The businesses that survive it sell maintenance, not repairs.
Roofers
Roofing has the worst reputation of any trade and the highest-value jobs in domestic work. Both facts point at the same strategy: stop competing with door-knockers and start selling to people who buy roofs on purpose.
Landscapers
Every landscaper eventually discovers that the beautiful garden they spent six weeks building generates one invoice, while the dull office car park they mow generates forty-eight.
The commercial half is a list
The accounts above all publish their contact details. GoLeadX searches a business type across every town you cover, crawls each site for the address, verifies it, and hands you a CSV. A search takes about a minute.
