The short version
Neither model is better in general. In-house wins on knowledge, availability and culture. Agencies win on breadth of skills, flexibility and cost at small scale. Many SMEs end up with a hybrid: one generalist in-house who owns the brand and content, with specialists for paid media, tracking and email.
| In-house hire | Agency | |
|---|---|---|
| Cost | Salary plus employer NI, pension, equipment, software and training | Monthly fee per service, plus ad spend |
| Skills | One person's strengths; generalists rarely go deep on PPC and tracking | Specialists for each channel |
| Business knowledge | Deep, day to day | Built up over time; depends on access you give |
| Availability | Full time, but holidays and sickness leave gaps | Agreed response times; cover within the team |
| Flexibility | Notice periods and employment law | Scale up or down; monthly with notice |
| Tools | You pay for each licence | Often included in the agency's own stack |
What an in-house marketer really costs
Salary is only the start. Recruiter guides for 2026 put the UK average for a digital marketing manager at around £54,000 (Digital Waffle) to £55,000 (Intelligent People), with London typically higher. Employer National Insurance in 2026/27 is 15% on earnings above £5,000 a year, which on a £54,000 salary is about £7,350. Add workplace pension contributions, recruitment costs, a laptop, software subscriptions (email platform, scheduling, design, analytics), training and the time someone spends managing them.
A more junior marketing executive costs less, but usually needs more direction and will not have deep experience across paid search, paid social, tracking and email at once. That is not a criticism; it is a lot of disciplines for one person.
Hiring also takes time. Advertising the role, interviewing and a notice period at their current employer can mean months before your new marketer starts, then more time while they learn your business. If the hire does not work out, you start again. None of this makes in-house wrong, but it belongs in the comparison alongside the monthly cost.
What an agency gives you, and what it does not
An agency gives you specialists who spend all day in Google Ads, Meta, Klaviyo or GA4 and see what works across many accounts. You pay per service, start quickly, and can change scope month to month. There is no recruitment risk or notice period.
The limits are real too. An agency will never know your customers as well as someone who sits next to your sales team. Response depends on the service agreed, not on walking over to a desk. And a poor agency can hide behind jargon. Protect yourself by keeping ownership of all ad, analytics and email accounts, asking for plain-English reports with costs per enquiry or sale, and avoiding long contracts.
The hybrid model
For growing SMEs, the most common setup we see working is one in-house marketer who owns brand, content, social posting and internal coordination, with an agency handling the technical, specialist channels: Google Ads, paid social, tracking and automation. The in-house person briefs and challenges the agency; the agency brings depth the in-house person cannot cover alone. A fractional marketing director is another option when you need senior strategy without a full-time hire.
To make a hybrid work, agree who owns what in writing. A simple split: the in-house marketer owns the calendar, brand assets, organic social and approvals; the agency owns campaign build, bidding, tracking and monthly reporting. Hold one short monthly review where both look at the same numbers, cost per enquiry or sale by channel, and agree the next month's priorities. That stops the common failure where the agency optimises for clicks while the in-house team is judged on something else.

Frequently asked questions
When should a business hire in-house instead of using an agency?
When marketing work is constant, varied and closely tied to daily operations, such as content, events and sales support, and you can afford a full salary plus employer costs. Specialist channels like PPC and tracking often stay with an agency even then.
Is an agency cheaper than an employee?
At small to medium scale, usually. A few specialist services cost far less than a salary plus employer NI and overheads. As spend and workload grow, an in-house team can become more economical for some tasks.
Can an agency work with our in-house marketer?
Yes, and this is often the best setup. We handle paid media, tracking and automation, and your marketer owns brand, content and coordination. We also train in-house staff at £45 an hour + VAT.
How do we avoid being locked into an agency?
Keep ownership of your Google Ads, Meta, GA4 and email accounts, with the agency added as a user. Avoid long fixed-term contracts. Our services are monthly, cancel with notice, and everything is set up in your accounts.
What about a freelancer instead?
A good freelancer can be excellent value for one channel. The risks are capacity and cover. Our freelancer vs agency comparison looks at that in detail for PPC, including account ownership and holiday cover.
