On paper, sourcing your own trades looks like the smart, frugal move. You find a carpenter on a forum, a tiler through a friend, a plumber and an electrician off a marketplace, and a painter at the end. Each quote is a little cheaper than a full package, and added up you've apparently saved thousands. Then the work starts, and you discover what you actually bought: a project with no one in charge of it but you.

The gaps between trades are where projects fail

A renovation isn't a stack of separate jobs. It's a sequence, and the hard part is the handovers. The electrician has to chase his wires before the tiler closes the wall. The plumber's points have to land exactly where the carpenter's vanity will sit. Waterproofing has to cure before tiling, and tiling has to set before the painter touches the skirting.

When one team runs all of it, those handovers are their problem. When you've hired five strangers who have never met, every handover is a seam — and every seam is where the buck gets passed.

Hire five trades and you haven't saved a project manager's fee. You've appointed yourself — unpaid, untrained, on nights and weekends.

“Not my scope” is the most expensive phrase in renovation

When something goes wrong across two trades — a leak behind new tiling, a socket in the wrong place, a cabinet that won't close over a misplaced pipe — separately hired contractors each have a powerful incentive to point at the other one. The tiler says the waterproofing was the plumber's job. The plumber says the tiler drilled through it. Both are paid and gone. The rectification, and the argument, is yours.

One accountable team can't play that game. If the leak is behind our tiling, it's ours to open up and fix — there's no one else to blame, which is exactly the point.

What you're really paying for

A single team isn't just convenience. It's:

  • One schedule. Trades sequenced so nobody waits on nobody, and the job actually finishes.
  • One point of contact. One person who knows the whole site, instead of five who each know a slice.
  • One warranty. When everything is under one roof, the after-sales call reaches the people who built it — not a void.
  • One standard. The same eye on the carpentry, the tiling and the paint, so the finishes agree with each other.

When sourcing your own makes sense

We'll be honest: for a single, self-contained job — repainting one room, swapping a tap, a one-off carpentry piece — going straight to a trade is perfectly sensible, and a full team is overkill. The case for one team is strongest exactly when the work crosses trades, which is most real renovations.

The bottom line

The cheapest-looking path on the spreadsheet is rarely the cheapest by the end, because it quietly prices out the one thing that makes a renovation go right: someone whose job is the whole thing. Pay for one hand to shake. When something needs answering for, you'll know exactly whose phone to ring — and they'll pick up.
