Where are plumber jobs actually advertised?

Why job boards show you so little

If you've been refreshing Indeed and Reed and seeing the same three roles from the same agency, that's not because plumbing has stopped hiring. It's because most plumbing vacancies never reach a general job board in the first place, or they reach it after the job's already been filled through a shorter route.

A plumbing firm with five vans doesn't have a recruitment team. When someone leaves, the owner or contracts manager asks the merchant rep, texts a couple of subbies they've used before, or puts a card in the window of the trade counter. Posting on a national board costs money and produces a pile of CVs from people with no Gas Safe registration and no idea what a 22mm compression fitting is. For a small employer that's a worse outcome than an empty ad. So the ad doesn't go up.

Larger employers — housing associations, M&E contractors, facilities management firms — do use job boards, but usually their own careers page or a framework portal first, and a public board only when internal channels and their retained agency haven't filled it. By the time you see it on Reed, it's often the second or third attempt.

The specialist places roles actually appear

Merchant counters and trade accounts. Plumb Center, City Plumbing, Wolseley (now Ferguson), Graham, and independent merchants often have a noticeboard, and reps hear about vacancies before anyone advertises them, because they're in and out of ten workshops a week. If you've got a trade account, use it — ask the counter staff directly.

CIPHE and IOP. The Chartered Institute of Plumbing and Heating Engineering runs a jobs section for members, skewed towards more senior, design, or building services roles rather than site-based install work, but worth checking if you're chartered or working towards it.

WaterSafe and Gas Safe Register listings. Neither is a jobs board, but firms that recruit self-employed engineers sometimes advertise through the trade press these bodies circulate — Heating and Ventilating News, Plumbing & Heating Monthly, H&V News — rather than through general recruitment sites.

Local authority and housing association frameworks. Councils and housing associations run responsive repairs and gas servicing contracts through named contractors (Mears, Wates, Sureserve, Aaron Services, among others depending on region). These contractors hire directly for their patches, often advertising on their own careers pages rather than a shared board, because the roles are tied to a specific contract and area.

Facebook and WhatsApp trade groups. For labour-only and self-employed work this is now one of the main channels, particularly for second fix, bathroom install, and heating engineer work. Regional groups (search your county plus "plumbers and heating engineers") post day-rate and contract work daily. It's informal, but it's where a lot of real, immediate demand sits.

Checkatrade, MyBuilder, TrustATrader. These are lead-generation platforms for self-employed plumbers rather than employers, but some small firms use them to find subcontractors to bring on, effectively as an unadvertised route into steady work with one employer.

Agencies, and the difference between the two kinds

There are two distinct types of agency in this trade, and conflating them wastes your time.

M&E and building services recruiters — firms like Fawkes & Reece, Rise Technical, Setsquare, or Concept Resourcing — place plumbers and heating engineers into commercial and industrial contracts: hospitals, data centres, large housing schemes, plant rooms. These roles usually want NVQ Level 2 or 3 in Plumbing and Domestic Heating, relevant ACS certificates (CCN1 for gas, plus appliance-specific ones like CENWAT, CKR1, HTR1 depending on the work), and often a CSCS or ECS card for site access. Pay is usually on JIB (Joint Industry Board) grading, which the agency will reference directly — knowing your grade level speeds up the conversation.

Labour-only subcontract gangs and site agents operate differently: less formal, often word of mouth or through a site agent who calls round known numbers when a contract needs bodies. This is common on new-build sites for volume housebuilders (Barratt, Persimmon, Taylor Wimpey, Bellway), where first and second fix plumbing is frequently subbed out in bulk. Getting on these lists usually means being known to a site agent or foreman from a previous job, or being recommended by someone who already is.

Both kinds of agency are worth registering with if you're geographically flexible, but they serve different work: one is PAYE or umbrella contract into a graded role, the other is day-rate self-employed on a specific site.

Internal movement and how firms actually fill roles

A meaningful share of plumbing vacancies are filled without ever being advertised anywhere, through routes that don't show up in a search:

• Apprentice progression. Someone who did their apprenticeship through JTL or a local college often stays with the same firm, or moves when their assessor or tutor hears of an opening elsewhere and mentions it. If you trained through JTL, staying in contact with your training provider after qualifying is a genuine route to hearing about openings before they're public.
• Gas engineers moving between service contracts. Boiler service and repair engineers often move when a letting agent, housing association, or British Gas-style national provider changes contractor, and the incoming contractor absorbs some of the outgoing firm's engineers directly rather than running a full recruitment process.
• Merchant and manufacturer referrals. Boiler manufacturers (Worcester Bosch, Vaillant, Baxi) run installer networks and sometimes point homeowners or firms towards accredited installers looking for extra hands, particularly around their approved installer schemes.
• Direct approach. Ringing round local firms and asking if they're taking anyone on, particularly smaller ones, works more often in this trade than in office-based work, because the hiring decision sits with one person who can say yes on the spot.

None of this is "networking" in the vague sense. It's specific: your training provider, your merchant rep, the site agent from your last contract, the manufacturer scheme your last employer was part of.

Timing and seasonality

Demand for plumbers is not flat across the year, and the type of work shifts with it.

Autumn (September–November) is when heating engineers see hiring pick up, ahead of the cold weather and the annual rush of landlord gas safety certificate renewals (a legal annual requirement for rented properties), so firms doing domestic servicing often take on extra ACS-qualified engineers now, which is roughly where the calendar sits as this is written.

Winter (December–February) brings emergency callout and breakdown work, particularly during cold snaps when boilers and pipes fail together. Firms sometimes bring on temporary or subcontract engineers specifically to cover the surge rather than committing to permanent headcount.

Spring and summer shift towards bathroom refurbishment, new-build second fix, and planned improvement contracts, since homeowners tend not to want their bathroom ripped out over Christmas. New-build hiring also tracks housing starts, which are seasonal and cyclical with the wider construction market — a housebuilder scaling up a site will often need plumbers in blocks, filled through the labour-only route above rather than individual adverts.

If your work is domestic gas servicing, aim your applications and direct approaches at September and October. If it's new-build install, watch site start dates on housebuilder websites and get known to the site agent before the plumbing fix stage begins, not after.

What to do next

Check your CSCS/ECS card, ACS certificates, and JIB grade are current and that you can state them plainly, because every route above will ask. Register with one M&E recruiter for graded contract work and separately try to get known to a site agent or two if new-build work interests you. Talk to your merchant rep. If you trained through JTL or a college, contact your old assessor. Join the regional Facebook or WhatsApp trade group for your area. And ring three or four small local firms directly and ask if they're taking anyone on — in this trade, that plain a question still works. jobmarket.pro reads full adverts against your certifications and JIB grading and prepares the application from your actual profile, which is useful once you've found the harder-to-reach roles above and need to apply properly.
