What are the real risks of outsourcing marketing delivery as a UK agency?

I want to ask this properly because I’ve seen both sides of it.

Everyone says:

“Just outsource it.”
“Hire overseas.”
“Lower your cost base.”

But I don’t think people talk enough about what can go wrong.

I’ve spoken to a few UK agency owners recently who tried outsourcing delivery and ended up more stressed than before.

Here’s what I keep hearing:

– The work technically gets done… but it doesn’t feel right for the UK market.
– Senior team members spend half their time rewriting things.
– Communication takes longer than expected.
– Nobody really “owns” the outcome.

On paper, the numbers look better.

In reality, margin disappears through management time and fixes.

At the same time, hiring fully UK-based teams for every role is expensive. Especially if you’re not at £100k+ MRR yet.

So it feels like agencies are stuck in this awkward middle:

Do everything in-house and squeeze margin.

Or outsource and risk losing control.

For those running agencies in the UK:

Have you outsourced?
Did it actually improve profitability?
What broke when you tried it?

I’m genuinely trying to understand how people are solving this without burning out the founder.
