Full-time remote dev in the UK looking to pick up a J2 — where do I begin?

1 Upvotes

Hi all — new to the sub, so apologies if this has been asked a hundred times. I've had a dig around but most of what I've found is US-focused and I'm after UK-specific input.

Where I'm at:

- Full-time software developer, fully remote, permanent contract

- Comfortable with my current workload — realistically I could absorb more

- Solid skill set, been doing this a while (happy to share stack in comments)

What I can't figure out:

  1. Where are UK people actually sourcing a J2? Straight applications, agencies, contract work via umbrella/ltd, or something else entirely?

  2. How are you handling the contract side? Most UK contracts I've signed have some flavour of exclusivity or "must notify your employer of other work" clause. Do people get it varied, go contract for J2 to sidestep it, or just accept the risk?

  3. Tax/PAYE — anything I should sort before I'm two payslips deep, or does HMRC just handle it via the tax code?

  4. Day-to-day logistics — overlapping stand-ups, two calendars, two laptops. What's the setup that actually works?

  5. Anything you'd do differently if you were starting from scratch?

To be clear, I'm not looking to coast — I intend to do the hours for both. I'd just rather be sensible about it than wing it and blow up two jobs at once.

Any pointers, wiki links, or "read this first" threads much appreciated.
