What Does a Chaser Do?

The Question

I was ready for the first fix stage of our extension and thought I had all the trades lined up.

What I didn’t realise was that there was one step before the electrician could begin.

A chaser.

That raised a much bigger question.

How do you know what needs to happen before each trade arrives?

My Experience

Once the blockwork and roof were completed, I asked the electrician to visit the extension and prepare a quotation.

We walked through the space together discussing where every socket, switch, light fitting and appliance connection would go.

As we talked, he marked everything out with spray paint directly onto the blockwork.

By the time we finished, we had a clear plan and he had everything he needed to prepare his quotation.

We then started discussing when he could begin the first fix.

He explained that all the wiring needed to be installed before the insulation and plasterboarding could begin.

As we finished the conversation, he said something I wasn’t expecting.

“Just let me know when the chaser is finished.”

I stopped him and asked,

“The who?”

He explained that before he could install any wiring, someone first needed to cut channels into the blockwork so the electrical cables could be recessed into the walls.

I’d planned for the electrician.

I hadn’t planned for the person who needed to come before him.

Fortunately, he mentioned it during the quotation visit rather than on the day he was due to start.

Had he arrived with his team ready to begin, nobody would have been able to do any work.

What I Learned

Looking back, the lesson wasn’t really about what a chaser does.

It was about understanding the sequence of trades.

Every trade depends on something being completed before they arrive.

Sometimes it’s obvious.

Sometimes it’s something you’ve never heard of.

From that point on, I made a habit of asking every trade the same question.

“What needs to be done before you can start?”

That one question helped me uncover work I hadn’t planned for and gave me time to organise it before it delayed the project.

Common Mistakes

Many homeowners focus on finding good trades, comparing quotations and agreeing prices.

Those things are important.

But it’s equally important to understand how each trade fits into the overall project.

Assuming the next trade can simply arrive and begin work can lead to unnecessary delays if preparatory work hasn’t been completed.

A simple conversation beforehand can often prevent those problems.

Practical Advice

Whenever you appoint a trade, don’t just ask when they can start.

Also ask:

• Is there anything that needs to be completed before you arrive?
• Will another trade need to visit first?
• How much notice do you need before you’re ready to begin?
• Is there anything I should organise now to avoid delays later?

Those questions take very little time to ask, but they can save days or even weeks during a project.

Looking Back

Looking back, I’m glad the electrician mentioned the chaser during our conversation rather than on the day he was due to begin.

It reminded me that even with careful planning, there would always be parts of the project I hadn’t considered.

From then on, I stopped assuming I knew the sequence of work.

Instead, I asked every trade what they needed before they arrived.

That simple habit helped me plan more effectively and avoid delays as the project progressed.

It’s one of those lessons that seems obvious in hindsight, but it only became obvious because someone took the time to explain it.
