In-House vs Outsourced vs Co-Managed IT

Your IT lead is on annual leave. The server goes down. Who picks it up?

The choice comes down to in-house vs outsourced vs co-managed IT, and most businesses seriously consider only two of the three. How you structure your IT support decides how quickly a question like that gets answered. At Cortec IT, we support businesses across Kent, London and the South East under all three arrangements — fully outsourced, co-managed, and project support alongside an existing team.

Why Your IT Support Model Matters

IT support tends to grow by accident rather than by design — one capable person who gradually becomes “the IT person”, or a support contract signed years ago and never reviewed. Reviewing how your IT is structured can help your business:

• Cover holidays, sickness and out-of-hours
• Access specialist skills when they are needed
• Reduce downtime and disruption
• Control technology costs
• Support future growth

The Three IT Support Models Compared

In-house vs outsourced vs co-managed IT comes down to one question: where does cover come from when something goes wrong? Each model puts that responsibility in a different place, and each suits a different size and shape of business. Here is how the three compare.

Five Questions to Ask Before You Decide

There is no universally correct answer. What matters is that the choice is made deliberately, rather than inherited from a decision someone made years ago under different circumstances.

The answers usually point to one model fairly quickly:

1. If our IT person left tomorrow, what would break first?
2. Who answers at seven o’clock on a Friday evening?
3. Of security, cloud, backup and compliance, which do we genuinely cover in-house?
4. Are we paying for capability we never use, or missing capability we need?
5. When did we last test a restore from backup, rather than just check it ran?

Comparing a salary against a monthly invoice is the most common mistake here, and it flatters the in-house option every time. For a wider view of where these risks sit, see our guide to IT issues and solutions for Kent businesses.

Frequently Asked Questions

The questions businesses ask us most often when they are weighing up in-house, outsourced and co-managed IT support.

What is co-managed IT support?

Co-managed IT is a shared arrangement in which your internal IT staff keep ownership of day-to-day support, while an external provider covers agreed areas alongside them — typically cyber security, cloud, escalations, out-of-hours cover and holiday gaps.

Can we keep our own IT person and still use an IT support company?

Yes — that is exactly what co-managed IT is for. Your IT person keeps ownership of the systems and users they know best, and the provider adds specialist skills and cover behind them.

Is outsourced IT cheaper than hiring in-house?

For most small and medium-sized businesses, yes — provided you count the full cost of the in-house option, including recruitment, training, security tooling and cover for absence. Larger organisations with enough volume to keep a full team busy may find in-house more economical.
