In-House Developers vs Agency vs Freelancer: Proven Best Fit
In-house developers, a software agency and freelancers are not three prices for the same thing — they are three different products, sold in three different units, carrying three different kinds of risk. This guide normalises all three to a comparable annual cost for the 2026 UK market, sets out the on-costs that make a salary roughly 1.5 times its headline figure, and compares the routes on speed to first release, delivery risk, control, knowledge retention and intellectual property. It includes a weighted scoring method you can run in twenty minutes, the hybrid core-plus-capacity model most UK companies end up with, the IR35 and copyright traps that catch contractor engagements, and the hiring mistakes that make the in-house route the least reversible of the three.
