Variations: why they cause so much conflict (and how to avoid it)

Two builders in workwear with arms crossed

This month’s article from R&R Building and Renovations Ltd – aka Leo and Tom – looks at how to factor in variations from the start.

If there is one thing guaranteed to cause tension on a building project, it is variations. Not dust. Not delays. Not even a client who can’t bake!

Ask almost any builder where projects start getting awkward and it usually comes back to the same sentence: “I thought that was included.”

And to be fair, most of the time nobody is trying to pull a fast one. Variations are just one of those parts of building that homeowners do not always understand – and honestly, a lot of builders are not great at managing them either.

Evolving projects

The reality is, projects evolve as they progress. Clients change their minds halfway through. Hidden problems appear once work starts. Someone decides they now want 20 Downlights instead of a pendant after the ceilings have already been skimmed. It happens. Variations are normal.

The problem is not the variation itself. The problem is usually communication. Earlier in our careers, we probably handled variations the same way a lot of builders do. A bit casual. A bit verbal. “We will sort it later.” Sometimes that works … until it absolutely does not.

Because your memory is unreliable. Especially halfway through a stressful project when everyone is tired and the client is convinced they definitely mentioned wanting a whole patio six weeks ago.

These days, we approach things very differently.

Detailed scope of works

At R&R, the original scope of works is detailed from the start. We make a real effort to explain what is included, what is excluded, and where potential additional costs could arise if things change later. Then, if something does change, we stop and deal with it properly before carrying on. Not at the end of the project.

That one change in approach has probably saved us more stress than any system or tool we have ever invested in.

If a client wants additional work, layout changes, upgraded finishes, extra lighting, different flooring – whatever it might be – we discuss it, price it, confirm it in writing, and only then move forward. Not because we are trying to be difficult – Because clarity protects everybody.

The truth is, most builders avoid dealing with variations properly because it feels awkward. You are mid-flow. The client asks, “Could we just move this?” and you think: “Yeah, probably.”

But those little “while you are here” moments stack up fast. A couple of extra hours here. An extra material run there. A small tweak that suddenly affects three other things. Before you know it, the project has drifted away from the original quote and your margin quietly disappears into thin air.

That is not the client’s fault if we have not communicated it properly.

Trust and transparency

One thing we have learned over time is that most clients are actually very reasonable when things are explained clearly and early.

What people struggle with is surprise. Nobody wants to reach the end of a project and suddenly hear:

“Oh by the way, there is another three grand to pay.”

That is where trust disappears. So now we deal with variations as they happen. Calmly. Clearly. In writing. Transparency beats tension every single time.

There is also the business side of it.

In our last column we talked about being busy versus being profitable, and variations sit right in the middle of that conversation.

If you are not managing them properly, you are quietly giving work away for free. You can be absolutely flat out, delivering brilliant work, and still slowly eroding your own margin project by project. Good variation management is not about squeezing every penny out of a client. It is about respecting the value of your time, your team and the work itself.

Building projects are living things. They move and evolve constantly. That is part of what makes construction interesting.But structure creates freedom.

Clear scopes. Clear communication. Clear variation process. That is what keeps projects healthy and relationships intact.

We are definitely not perfect, and a lot of this has been learned the hard way over the years. But the more organised and transparent we have become around variations, the smoother our projects have become.

Less tension. Less confusion. Better margins. Better sleep. And honestly, these days, decent sleep feels like a luxury.
