How to Find Subcontract Work in Construction — A Practical Guide
The first few months of self-employment are the hardest. You've gone out on your own, you've got everything set up, and then the question hits — where does the actual work come from?
For most trades, the answer is simpler than it feels at the time. Here's where subcontract work in construction actually comes from and how to get yourself in front of it.
Existing contacts — the obvious starting point
Most tradespeople who go self-employed get their first work from people they already know. Former employers, former colleagues, contractors they've worked alongside. These relationships are warm — they already know your work.
Before you go self-employed, or in the first week after, contact every relevant person you know and tell them you've gone out on your own. Be specific — "I'm now taking on subcontract electrical work. If you need someone or hear of anyone who does, I'd really appreciate being put in touch."
Don't assume people will think of you. Tell them you're available and tell them what you do.
Labour agencies and subcontract agencies
Labour agencies specialise in placing skilled tradespeople with contractors. For most trades — electricians, plumbers, groundworkers, steel fixers, shuttering joiners — there are agencies that specifically supply labour to construction contractors.
Registering with several agencies costs nothing. You submit your qualifications, CSCS card, and relevant tickets. They contact you when work matches your skills and location.
The work tends to pay slightly less than direct subcontracting but the lead time is short — sometimes next-day starts. Useful for filling gaps and getting established.
Construction sites — knocking on doors
It sounds old fashioned but it works. Drive past active sites, find out who the main contractor is (planning portals show this, or the site hoarding will have the contractor's name), and contact their buying or labour department.
Many smaller contractors take on subbies directly without going through agencies. A phone call or email to the right person — "I'm a [trade] in your area, CSCS carded, [relevant qualifications], available from [date]" — is all it takes to get on their books.
Construction job boards
Online platforms that list subcontract work include:
Construction Jobs (constructionjobs.co.uk) Brief Your Market MySuB LinkedIn — increasingly used for commercial construction connections Domestic side: Checkatrade, MyBuilder, Rated People
For CIS subcontractors, the commercial construction boards tend to be more relevant than the domestic lead-generation sites.
Building a reputation on site
The most reliable long-term source of work is being someone other people want to work with. That means turning up on time, doing what you said you'd do, being easy to work alongside, and not causing problems for the main contractor.
Contractors use the same subbies repeatedly when they can. The subbies who get called first are the reliable ones — not necessarily the cheapest or the most skilled, but the ones who don't create headaches.
Make it easy to be called. Answer your phone. Return calls promptly. If you can't take a job, say so early rather than messing someone's programme. The construction world is smaller than it looks — reputation travels.
Specialise to stand out
As you build experience, developing a specialism makes you more attractive to specific contractors and allows you to charge a premium. EV charger installation for electricians. Underfloor heating for plumbers. Basement waterproofing for builders. Renewable energy systems.
Specialists are harder to replace and can usually command better rates than generalists — and the contractor pool that needs your specific skill is smaller, making it easier to get known.
Keeping the pipeline full
The trap many subbies fall into is being too busy to look for the next job until the current one ends — then spending two weeks finding something, losing two weeks of income. Keep a light awareness of what's coming up even when you're busy.
A simple note of who might have work in six weeks, a message to a contact you haven't spoken to in a while — these keep the pipeline moving without taking much time. It's the self-employed version of not putting all your eggs in one basket.
