The best clients for a contractor arbitrage business are the ones who send repeat work without you having to re-sell yourself every time. Housing associations, letting agents, and landlord portfolios fit that description. Your network gets you your first job. Those institutional channels build a real pipeline. Here is how to find clients for contractor arbitrage, ranked by what works at each stage.
TL;DR
- First jobs: your network and local letting agents - free, fast, and still the most reliable start.
- Repeat volume: housing associations and social housing repairs - get on their approved lists via Constructionline.
- Online presence: a Google Business Profile costs nothing and converts well for local maintenance searches.
- Paid platforms: Checkatrade, Bark.com, and Rated People work once you can convert leads; they do not replace the others.
- The client mix that works: a couple of institutional clients for steady volume, plus a referral engine for margin jobs, plus one or two platforms for top-up leads.
Why finding clients is different in contractor arbitrage
When you are a sole-trader tradesperson, you are selling your own hands. You compete on price, availability, and how trustworthy you seem at the door.
When you are doing contractor arbitrage - winning the job and subcontracting the delivery - you are selling something different: managed outcomes. You are the person the client never has to chase. The job gets done, the subs are coordinated, and any snagging gets fixed without a fight. That is a more valuable thing to sell than a day rate.
The channels are the same. The pitch is different. And the clients who value the managed-outcome pitch most are the clients who commission work regularly - letting agents, housing associations, portfolio landlords.
Hadri hammered this into me early on. "It's not the price - it's the service." The clients worth having are not shopping on price. They have been let down by cheap trades. They will pay more for someone who picks up the phone, shows up when they say they will, and sorts it.
That changed how I approached every single channel below.
Your network: still the fastest start
The first job in a new contractor arbitrage business almost always comes from someone who already trusts you. That is not a fluke - it is how new businesses work in every service sector.
The mistake is being vague about it. "I've started a building company" gets a nod and a change of subject. "I run a property maintenance company - if you or anyone you know needs a renovation, a damp fix, an emergency repair or a full refurb managed properly from quote to handover, I am the person to call" gets referrals.
Be specific. Say what you do, what size jobs you take, and what area you cover. Then make it easy to pass on: send a short message people can forward, or a business card with a clear line on the back.
Post in local homeowner and landlord groups on Facebook and Nextdoor. Not ads - genuine posts answering people's questions. Someone asks which tradesperson is reliable locally. You answer helpfully. That is how you get the first call.
Letting agents and landlords: the repeat-work machine
Letting agents manage dozens of properties. Every property needs ongoing maintenance - gas checks, leaks, plumbing callouts, end-of-tenancy repairs, redecorations. The agency's job is to keep those properties rented and in good order without managing fifteen different tradespeople.
A contractor arbitrage operator who can take a maintenance call at any hour, assign the right sub, and report back that it is done is worth a lot to a busy letting agent. Most of them have had bad experiences with trades who go quiet, miss jobs, or argue about pricing. You are the alternative.
How to approach letting agents:
- Find three to five independent letting agents in your area.
- Call or walk in during a quiet morning. Ask for the property manager or branch manager.
- Keep it short: you run a local maintenance company, you coordinate all trades, you never leave a job without confirmation it is done and the client is happy. Can you quote on their next job?
- Follow up by email the same day. Not a long pitch - one sentence and your details.
- When you get a job, do it well and ask for the next one.
Portfolio landlords with five or more properties work the same way. A landlord managing that much property without a reliable maintenance company is already frustrated. Find them in landlord Facebook groups, on local property investor meetups, or through estate agents.
Housing associations and social housing: the institutional pipeline
This is where a contractor arbitrage business can build serious volume. Housing associations run hundreds or thousands of properties. They need responsive repairs, void property works, damp and mould remediation, decorating, electrical and gas - all of it, ongoing, across a portfolio.
They do not hire on a handshake. You need to be on their approved contractor list first.
The route most housing associations use is Constructionline, the government-backed pre-qualification register. Gold membership is the tier that meets the Common Assessment Standard required by most public bodies. Specific membership fees vary by tier and turnover - check the Constructionline website for current pricing.
Once you have Constructionline Gold, go to find-tender.service.gov.uk and search for housing associations and councils in your area. Many publish open notices when they are adding to their approved lists. Others you have to contact directly - email their procurement team and ask whether their list is open for new applications.
The pre-qualification pack usually asks for:
- Public liability insurance (typically at least £2 million; many housing associations require £5 million)
- Employers liability insurance (£10 million is a common minimum)
- Health and safety policy
- Evidence of previous similar work
- Financial references
Get that paperwork in order before you apply. It is the same pack you will send to every housing association.
Hadri built most of his housing association relationships early on through exactly this route - getting pre-qualified, showing up prepared, and delivering on the first job. He was very clear with me: the first job with any institution is the audition. Do not treat it as a normal job. Every report, every bit of communication, every sign-off has to be tight. You win the next ten jobs in how you handle the first one.
Google Business Profile: free and underused
A Google Business Profile is the closest thing to a free billboard that actually converts. When someone searches "emergency plumber" or "property maintenance" in your area, the Map Pack results appear above the organic listings. Those are Google Business Profile listings.
Claim your profile on day one of trading. Fill in every section:
- Business category (Property maintenance, General contractor, or both)
- Service area (your operating radius)
- Services list (be specific - damp treatment, emergency repairs, full refurb, and so on)
- Photos of completed work as soon as you have them
- A description in plain words that includes your location and what you do
Ask every satisfied client for a Google review. One real review puts you ahead of half the competition. Five puts you at the top of the Map Pack for your area.
It costs nothing and compounds over time. It should be set up before you spend a penny on paid advertising.
Paid lead platforms: useful at scale, expensive to start
Checkatrade, Bark.com, and Rated People all work - but none of them are where you start when you are building the business from scratch.
Checkatrade lists you in their directory. Members report typical all-in costs of roughly £800 to £1,500 a year depending on trade and postcode, on a 12-month minimum contract, with lead-related fees on top. You do not appear in standard searches until you are on a paid plan. The value is the directory traffic and the review system - clients who search Checkatrade trust the vetting process. Worth testing once you can convert leads efficiently.
Bark.com works on a credit model. You buy credits (around £1.80 plus VAT each at last check) and spend them to respond to jobs posted by customers. Each lead is shared with up to five contractors, so you are competing on price and speed of response from the moment the lead drops. Good for volume when you need to fill gaps.
Rated People runs a subscription model with leads shared with up to three contractors. Fewer competitors per lead than Bark, but the subscription cost adds up if the leads do not convert.
Track every lead and what it costs you to convert it. If the cost per won job from a platform exceeds what referral or institutional work costs you, cut the platform and put the effort into more referrals.
Is contractor arbitrage the same as construction arbitrage?
Yes. The model is identical - win the client, subcontract the delivery, keep the margin. The terms describe the same thing.
Contractor arbitrage is the broader term. Any service sector where you act as the middleman - creative work, cleaning, logistics - uses the same structure. Construction arbitrage is contractor arbitrage applied specifically to building, trades, and property maintenance.
Construction Arbitrage is where tradespeople and operators learn to win the work, manage the trades, and keep the margin.
We talk about contractor arbitrage and construction arbitrage as interchangeable because they are. If you have come across one term before the other, it does not matter - the mechanics are the same.
Building the client mix that lasts
The businesses that build slowly and then grow fast are the ones with the right client mix from the start:
- One or two institutional clients (housing association or letting agent) that give you steady, reliable volume.
- A referral engine from the network that sends the better-margin homeowner jobs.
- One paid platform testing in the background, tracked against a cost-per-job target.
That mix means you are never entirely dependent on one source, and the steady volume from institutional clients keeps your subs active and your pipeline predictable.
When I started building this properly, how much money you can actually make from contractor arbitrage was a question I had no good answer to. Once the institutional clients came in and the referral engine started working, the maths became very clear. Volume from repeat clients is where the real money sits - not one-off jobs you fought hard to win.
If you are at the beginning and want to understand the full model before you go looking for clients, that is worth reading first. The way you position yourself in every channel depends on whether you have a clear answer to "what do you actually do?"

FAQ
Is contractor arbitrage the same as construction arbitrage?
Yes, same model, different name. Contractor arbitrage is the broader term - any sector where you win the job and subcontract the labour. Construction arbitrage is contractor arbitrage applied specifically to building and trades work. Both mean you hold the contract, your subbies do the work, and you keep the margin in between.
How do I get on a housing association's approved contractor list?
Start with Constructionline, the pre-qualification register that most housing associations and councils accept. Register for Constructionline Gold, then look up housing associations in your area on find-tender.service.gov.uk and contact their procurement team to ask about applications to their approved list. Some run open lists; others only add contractors when there is a gap.
What is the fastest way to get a first client?
Your existing network. Tell everyone you know - clearly and specifically - that you run a company handling building and maintenance work end to end. The first job almost always comes from a warm contact or a local Facebook group, well before any paid platform starts producing.
Do I need Checkatrade to find clients?
Not at the start. Checkatrade costs roughly £800 to £1,500 a year to appear in standard search results, on a 12-month term, with lead fees on top. That is a real spend before you have systems to convert leads consistently. Your network, Google Business Profile, and local letting agents will get you further for free in the early months.
How many clients do I need to start making money?
One regular client can be enough if it gives you steady volume - a letting agent with ten properties needing maintenance, or a small housing association. Three to five reliable sources covering different job types is a healthy foundation. You want repeat work and referrals, not a constant scramble for new leads.
