Staff augmentation pricing gets confusing fast, mostly because “add a developer to our team” can mean a junior contractor at £2.5k a month or a senior product engineer well into five figures, and both get called the same thing.

Here’s what actually determines the number, and how to sanity-check a quote.

The starting range

Codtronix engagements start from £2.5k monthly per specialist, with senior and specialist roles (AI, cloud, technical leadership) climbing well beyond that as seniority and scarcity increase. The honest way to think about the range: £2.5k buys you junior-to-mid capacity or a part-time arrangement, and the number moves up from there in line with seniority, discipline, and whether you need one specialist or a coordinated squad.

Product squads — a small team spanning product, design, and engineering working against one roadmap — are priced as a team rate once shape and coverage are agreed, rather than summed from individual rate cards.

What changes the number

Seniority. A senior engineer or product lead costs more per month than a mid-level one, but usually needs far less oversight, produces fewer review cycles, and is less likely to introduce decisions you’ll need to unwind later. Cheaper monthly rates don’t reliably mean lower total cost once management overhead is counted.

Discipline. Specialist AI, cloud, or security engineering typically sits at the higher end of the range. General product engineering sits in the middle. The rate reflects scarcity and risk, not just hours.

Team shape. One embedded specialist is priced differently from a coordinated squad, because a squad needs internal coordination the individual doesn’t.

Overlap and availability. Full-time engagement costs less per hour than part-time or high-overlap-hours arrangements across time zones, since part-time capacity is harder to plan around on both sides.

Notice and continuity terms. Shorter notice periods and more flexible scaling terms typically carry a small premium over a longer fixed commitment, because they shift risk back onto the provider.

Staff augmentation vs the alternatives

This is usually a three-way decision, not a two-way one:

  • A freelancer is often cheaper per hour and a good fit for a bounded, well-specified task where you already have someone to manage the work day to day.
  • An in-house hire is the right answer for capability you’ll need indefinitely, once the recruitment timeline and management overhead are worth it.
  • Staff augmentation sits between the two: senior capacity without a multi-month hiring cycle, for work that’s real but not necessarily permanent, or while you’re still validating the team shape you’ll eventually hire for.

None of these is universally cheaper — the honest comparison is total cost of the outcome, not the headline monthly number. A freelancer at half the monthly rate can cost more overall if the work needs more management time than you have, or if continuity breaks when they move to another client.

Questions worth asking before you sign

  • Is this priced per specialist, or as a team rate — and does that match how the work is actually structured?
  • What happens to cost and continuity if the engagement needs to scale up or down after month two?
  • What’s the actual notice period, and what does it cost to exit early?
  • Who provides technical leadership and review — is that included, or a separate cost?
  • Can you see how this specialist or team would integrate with your existing tools and rituals before committing?
