For many small and medium UK businesses, outsourced IT support is the more practical starting point because it can provide a wider pool of skills, planned continuity and predictable monthly spend without recruiting a full internal team. In-house IT becomes more compelling when your organisation has enough steady workload to justify several IT roles, relies on highly bespoke systems, or needs constant on-site knowledge. Growing businesses often combine both in a co-managed model.
At a glance
Which model is likely to fit?
SMEs that need breadth without a full internal team
Best when you need helpdesk, Microsoft 365, networking, security, monitoring and escalation but do not have enough IT workload to justify several specialist employees.
Businesses with specialist systems and constant internal demand
Best when IT is core to the product, hands-on presence is critical, or there is enough work to keep multiple internal technical roles fully occupied.
There is no universal employee-count cut-off. The correct answer depends on your systems, locations, operating hours, security requirements, internal management capacity and the level of service you are comparing.
What in-house and outsourced IT support actually mean
In-house IT support
In-house IT means employing one or more IT professionals directly. They work inside your organisation, report to your management team and build detailed knowledge of your users, systems, processes and history.
- Direct control over priorities and workload
- Strong day-to-day knowledge of the organisation
- Immediate physical presence during staffed hours
- Coverage limited by the size and skills of the internal team
Outsourced IT support
Outsourced IT means contracting an external provider to deliver agreed IT support and management services. You retain business ownership and decision-making; the provider supplies people, processes and tools under a contract and SLA.
- Access to a broader technical team
- Service continuity is the provider’s staffing responsibility
- Predictable recurring cost where the contract is fixed
- On-site presence, out-of-hours helpdesk and project work depend on the package
Many managed providers offer continuous monitoring, but human out-of-hours support varies by plan. If round-the-clock support matters, check exactly what is included in the SLA. UK IT Services also has a dedicated 24/7 IT support service for organisations that need that level of cover.
In-house vs outsourced IT support: side by side
| Factor | In-house IT | Outsourced IT |
|---|---|---|
| Cost structure | Salary plus employer NI, pension, recruitment, tools, training, management and cover. | Usually a recurring fee per user, device or service, plus any agreed extras. |
| Expertise | Deep knowledge of your environment; breadth depends on team size and recruitment. | Potential access to multiple disciplines across helpdesk, cloud, networking and security. |
| Availability | Normally follows staffed hours unless shifts or on-call cover are funded. | Monitoring and helpdesk hours depend on the contract; 24/7 is not automatic. |
| Physical presence | Strongest option for immediate, everyday on-site presence. | Remote-first in many models; scheduled or reactive onsite support may be included or charged separately. |
| Continuity | Single-person teams carry sickness, holiday and resignation risk. | Provider is responsible for maintaining staffing coverage under the contracted service. |
| Scaling | Requires hiring, training or restructuring. | Usually easier to scale, subject to minimum seats, notice periods and contract terms. |
| Business familiarity | High through daily internal exposure. | Built through onboarding, documentation, account management and regular reviews. |
| Security capability | Depends on internal expertise, tooling and budget. | May include specialist security capabilities, but only if explicitly included and correctly configured. |
| Management burden | You recruit, develop and manage the team. | You manage the provider relationship, contract, governance and performance. |
| Best fit | Complex or highly bespoke environments with enough workload for a capable internal team. | Organisations needing broad support capacity without building a full department. |
What does an in-house IT employee really cost?
The salary is only the starting point. The National Careers Service currently lists IT support technician pay at roughly £24,000 for a starter to £36,000 for an experienced technician. More senior, security-focused, cloud or infrastructure roles can sit outside that range, so the right benchmark depends on the capability you need.
For the 2026/27 tax year, employer National Insurance is 15% above the £5,000 annual Secondary Threshold. In most automatic-enrolment pension schemes, the minimum employer contribution is 3% of qualifying earnings, subject to the scheme rules.
| Cost element | Estimated amount | How it is treated |
|---|---|---|
| Salary | £36,000 | Experienced IT support salary used for this comparison. |
| Employer National Insurance | £4,650 | 15% of salary above the £5,000 Secondary Threshold. |
| Minimum employer pension | Approx. £893 | 3% of qualifying earnings between £6,240 and £36,000 in this example. |
| Recruitment, tools, training and other annual overhead | £5,000 | Estimated annual allowance for recruitment, tools and training; actual costs vary by employer. |
| Estimated annual employment cost | Approx. £46,543 | Before enhanced benefits, office space, management time, absence cover or additional specialist roles. |
One employee and a managed service are not automatically equivalent. A single internal generalist cannot be available every hour, cover every specialist discipline and provide their own sickness or holiday backup. Compare the service capability you need, not just the cheapest headline number.

How much does outsourced IT support cost?
Managed IT support is commonly priced per user, per device, per site, or as a fixed bundle. UK IT Services’ separate 2026 pricing guide currently describes a broad managed-support range of roughly £40 to £150 per user per month, with many small businesses clustering around £60 to £80 per user per month. Actual pricing depends on what is included.
Business-hours helpdesk only is not the same product as support that includes 24/7 incident response, security monitoring, backup management, Microsoft 365 administration, onsite allowance, strategic reviews and project work.

| Users | Outsourced annual cost | One in-house hire | What the numbers do not tell you |
|---|---|---|---|
| 10 | £8,400 | Approx. £46,543 | Outsourcing is typically much easier to justify financially if the service scope fits. |
| 25 | £21,000 | Approx. £46,543 | Still compare inclusions, onsite needs and security requirements. |
| 50 | £42,000 | Approx. £46,543 | The figures are close, but one employee may not provide equivalent breadth or continuity. |
| 75 | £63,000 | Approx. £46,543 | The outsourced figure is above the one-hire example, but realistic internal cover may require more than one role. |
| 100 | £84,000 | Approx. £46,543 | One employee is unlikely to represent equivalent breadth or continuity; model the internal team you would actually need. |
For comparison, the outsourced column assumes £70 per user per month. The in-house column uses a £36,000 salary plus employer National Insurance, the minimum employer pension contribution and a £5,000 estimated annual overhead. Actual costs vary by salary, benefits, tooling, service scope and provider.
Pros and cons of each model
In-house IT support
Advantages
- Immediate day-to-day organisational context
- Direct internal control over priorities
- Strong fit for bespoke systems and specialist equipment
- Easy face-to-face collaboration with other teams
- Can become strategically valuable where technology is core to the business
Disadvantages
- Recruitment and retention burden
- Sickness, holiday and resignation can create cover gaps
- One or two people cannot be experts in every discipline
- Tools, training and certifications are your responsibility
- True out-of-hours cover usually requires more staffing
Outsourced IT support
Advantages
- Broader team and escalation routes
- Provider manages staffing continuity
- Predictable recurring cost when scope is clear
- Faster access to specialist cloud, network and security skills
- Can scale without running a full recruitment cycle
Disadvantages
- Less everyday physical familiarity than a colleague in the office
- Quality varies significantly between providers
- Contract minimums, notice periods and exclusions may apply
- Onsite or project work can cost extra
- Privileged provider access means security due diligence is essential
Which IT support model fits different business sizes?
Headcount is useful, but it is only a proxy for workload. A 25-person engineering company with specialist systems may need more hands-on support than a 100-person cloud-first professional-services firm.
| Business size | Likely starting point | Why |
|---|---|---|
| 1–24 users | Outsourced | Usually difficult to justify enough internal IT roles to match a provider’s breadth and continuity. See our small business IT support options. |
| 25–49 users | Outsourced or light hybrid | Support demand grows, but a full internal department may still be inefficient. |
| 50–99 users | Compare outsourced, co-managed and internal options | Cost starts to converge, while workload, sites, security and operating hours become more important than headcount alone. |
| 100+ users | Case-specific; co-managed is common | Enough demand may exist for internal ownership while an MSP adds specialist capacity, projects, monitoring or out-of-hours cover. |
When in-house IT is the better choice
- Technology is central to your product or intellectual property
- Highly specialised equipment needs regular hands-on intervention
- You have enough steady workload for multiple technical roles
- Deep internal context is more valuable than broad pooled coverage
When outsourcing IT makes more sense
- You need several skill sets but cannot justify a full department
- You operate across multiple sites or support remote users
- Predictable cost and staffing continuity matter
- You need stronger escalation, monitoring or specialist security capability
Co-managed IT: combine internal knowledge with external depth
Co-managed IT lets an internal IT lead or small team retain ownership of the environment while an MSP handles agreed specialist or operational responsibilities. It can be a better answer than forcing a business into a fully in-house or fully outsourced model.
| Responsibility | Internal IT | MSP |
|---|---|---|
| Business-specific system knowledge | Primary | Documented backup |
| Walk-up / floor support | Primary | Overflow if agreed |
| Helpdesk overflow | As capacity allows | Primary |
| Microsoft 365 administration | Shared | Shared |
| Security monitoring | Oversight | Operational delivery if contracted |
| Network / cloud escalation | First-line context | Specialist escalation |
| Major incidents | Business coordination | Technical response under agreed process |
| Projects and migrations | Requirements and governance | Engineering capacity |
| After-hours escalation | On-call if required | Available only if contracted |
Our managed IT support service can be structured around full outsourcing or support for an existing internal team, depending on the responsibilities you want to keep.
We can scope an MSP layer around the work your team wants to retain, such as escalation, security monitoring, projects or out-of-hours cover.
How do SLAs and response times compare?
An internal team can set its own service targets, but there is no external contract enforcing them. With an MSP, the service level agreement (SLA) should state support hours, priorities, response targets, escalation, incident notification and any resolution targets or service credits.
The National Cyber Security Centre says clear SLAs should define response and resolution expectations. Its SME guidance notes that a response time of one business day is a standard starting point for general or minor requests, while under one hour is a standard starting point for urgent issues. For routine medium-priority issues, a 2–3 business day resolution target can be a useful starting point, depending on complexity.
Ask every provider to define
- Support hours and what “24/7” actually covers
- Priority levels and how a critical incident is defined
- Response time vs resolution time
- Escalation path and named accountability
- Security incident notification process
- Scheduled maintenance windows
- Reporting, service reviews and contract remedies
How cyber security changes the decision
Cost is only one part of the decision. The UK government’s Cyber Security Breaches Survey 2025/2026 reported that 43% of UK businesses identified a cyber security breach or attack in the previous 12 months, equivalent to approximately 612,000 businesses. The survey notes that some attacks may go unidentified, so the measured figure may understate total prevalence.
That does not mean outsourcing is automatically safer. An MSP may have privileged access to your systems and data, which makes supplier security and contract design critical.
The NCSC advises SMEs to look for recognised security certifications such as Cyber Essentials Plus or ISO 27001, review client references, insist on clear SLAs and responsibilities, check incident-notification arrangements, apply least-privilege access, verify backup and recovery processes, and plan for contract termination.
Whether your security capability is internal or outsourced, make sure responsibility is explicit. “The MSP handles security” is not a control. Named owners, documented processes, configuration standards, testing and reporting are. If you need specialist help alongside IT support, see our cyber security services.

What should an outsourced IT support package include?
Before comparing a monthly fee with an internal salary, define exactly what the provider is responsible for. Depending on the package, managed IT support may include:
Often included in managed support
- Remote helpdesk
- Device and service monitoring
- Patch management
- Endpoint security administration
- Microsoft 365 user and tenant administration
- User onboarding and offboarding
- Backup monitoring
- Network support
- Vendor coordination
- Service reporting and reviews
Often package-dependent or separate
- Hardware and software licences
- Major cloud migrations
- Office moves and cabling
- Large transformation projects
- Regular onsite presence
- Out-of-hours human helpdesk
- Penetration testing
- Business continuity exercises
- Specialist compliance consulting
Ask the provider to give you a written inclusions-and-exclusions schedule. A low monthly price is not good value if the services you actually need are repeatedly billed as extras.
What should you check before choosing an outsourced IT provider?
Security and access
- Which recognised security certifications do you hold?
- How is privileged access protected and logged?
- Do you enforce MFA / 2-step verification on administrative access?
- How quickly will you notify us about a security incident?
- How are subcontractors and supply-chain risks managed?
Service and contract
- What are the response targets by priority?
- Which support hours are included?
- What is excluded from the monthly fee?
- How often will we receive reporting and service reviews?
- What are the notice, renewal and termination terms?
Ownership and exit
- Who controls domains, tenants, licences and admin accounts?
- Will we retain appropriate administrative access?
- What documentation is maintained?
- What must be handed over if we leave?
- How will data be returned or securely deleted?
Capability and fit
- Can you provide references from comparable organisations?
- Where is support delivered from?
- Which platforms and vendors do you support deeply?
- How are major incidents escalated?
- Who owns the relationship and strategic roadmap?
How do you move from in-house to outsourced IT?
A safe transition should be documented and staged. The exact order depends on your environment, but a practical handover normally includes:
Discovery and scope
Agree users, sites, devices, systems, business-critical services, support hours and responsibilities.
Asset, licence and access inventory
Document devices, networks, cloud services, domains, licences, admin accounts and third-party suppliers.
Security and backup checks
Review privileged access, MFA, patching, endpoint protection, backup status, restore processes and known risks before control changes hands.
Knowledge transfer
Capture network diagrams, recurring issues, vendor contacts, business-critical workflows and known technical debt.
Tooling and service launch
Deploy agreed monitoring/support tools, test ticket routes and escalation, and communicate the new support process to users.
Post-transition review
Check unresolved issues, access rights, documentation quality, reporting and whether the SLA is working as expected.
UK government guidance says TUPE can apply to some service provision changes, including outsourcing. If employees currently perform the work that may be transferred, get appropriate HR or legal advice before changing roles or employment arrangements. This article is not legal advice.
Seven questions to answer before you choose
| Question | Points more toward in-house | Points more toward outsourced |
|---|---|---|
| How much hands-on support is needed every day? | High, constant physical demand | Most work can be remote with planned onsite visits |
| How broad are the skills required? | A narrow, highly specialised stack | Multiple disciplines across cloud, network, security and helpdesk |
| Can you keep several IT staff fully occupied? | Yes | No |
| How important is out-of-hours cover? | You can fund internal shifts / on-call | You want contracted external cover |
| How quickly will headcount change? | Stable and predictable | Growing, shrinking or seasonally variable |
| How much management capacity do you have? | You want to recruit and manage a technical team | You prefer to manage a supplier relationship and SLA |
| Where does business context matter most? | Daily internal knowledge is essential | Documented processes and account management are sufficient |
If the answers are mixed, that is a strong sign to consider co-managed IT rather than forcing the whole function into one model.

Frequently asked questions
Is outsourced IT support cheaper than hiring in-house?
For many small and medium UK businesses, outsourced support can cost less than maintaining equivalent internal coverage because an employee’s salary is only one part of the true cost. Employer National Insurance, pension contributions, tools, training and cover for absence also matter. The right comparison depends on service scope and the number of internal roles you would otherwise need.
At what company size does in-house IT support make sense?
There is no universal headcount. In-house support becomes more attractive when there is enough steady work to justify multiple internal specialists, or when the business needs continuous hands-on knowledge of highly bespoke systems. Many growing organisations use a co-managed model instead of switching completely to one side.
Can I use both in-house and outsourced IT support?
Yes. This is commonly called co-managed or hybrid IT. An internal IT lead can retain business knowledge and day-to-day ownership while an MSP provides specialist skills, monitoring, security, projects, escalation and out-of-hours cover where contracted.
Does outsourced IT support include 24/7 helpdesk support?
Not automatically. Many managed providers offer 24/7 monitoring, but human helpdesk and out-of-hours incident response depend on the service plan and SLA. Ask for the support hours, priority definitions, response targets and escalation process in writing.
What should an outsourced IT support package include?
Depending on the package, managed IT support may include helpdesk, monitoring, patching, endpoint security, Microsoft 365 administration, backup monitoring, onboarding and offboarding, network management, reporting and strategic reviews. Hardware, licences, projects, office moves, onsite visits and out-of-hours work may be separate, so exclusions should be confirmed before signing.
Is outsourced IT support secure?
It can be, but provider due diligence is essential because an MSP may have privileged access to systems and data. The NCSC recommends checking recognised security certifications, SLAs, incident notification, access controls, backups, supply-chain risk and exit arrangements.
Will we lose control of our systems if we outsource IT?
You should not surrender strategic control. Your contract should clearly set out ownership and access arrangements for business data, domains, licences, administrative accounts and documentation, as well as what must be returned or transferred if the relationship ends.
How long does it take to switch to outsourced IT support?
Timelines vary with complexity. A safe transition normally includes discovery, asset and access inventory, security and backup checks, knowledge transfer, tool deployment, user communication and a controlled handover. The provider should agree responsibilities and escalation routes before the go-live date.
Can TUPE apply when IT services are outsourced?
Potentially. UK government guidance explains that TUPE can apply to some service provision changes, including outsourcing. Whether it applies depends on the circumstances, so businesses with employees currently carrying out the work should obtain appropriate HR or legal advice before restructuring roles.
The examples on this page use a £36,000 annual salary, employer National Insurance at 15% above the £5,000 Secondary Threshold, a 3% employer pension contribution on qualifying earnings, and £5,000 per employee for estimated recruitment, tools and training overheads. The outsourced comparison uses £70 per user per month. Actual costs will vary according to salary level, benefits, business requirements, service scope and provider pricing.
