Quick Framework: When to DIY
DIY makes sense if:
- Budget is under £3k/month (agency fees eat too much)
- You have 10+ hours/month to dedicate
- You're willing to invest in learning the platform properly
Otherwise, get help. The cost of learning mistakes usually exceeds agency fees.
True Cost Comparison
| Factor | DIY | Agency |
|---|---|---|
| Monthly Cost | Your time (10-20 hrs × your rate) | £500-2,000/month |
| Learning Curve | 3-6 months of mistakes | Skip entirely |
| Wasted Budget (First 90 Days) | £2,000-5,000 typical | Near zero |
| Creative Production | Your responsibility | Often included |
| Strategic Advice | Self-taught | Based on 100+ accounts |
| Platform Updates | Discover when things break | Proactive adaptation |
The Dirty Secret: Default Settings Are Designed to Drain Your Budget
LinkedIn's Campaign Manager has three hidden settings enabled by default that benefit LinkedIn, not you:
- 1. Audience Expansion: Shows ads to people outside your targeting
- 2. LinkedIn Audience Network: Places ads on random third-party sites
- 3. Maximum Delivery bidding: Optimises for volume, not value
Most DIY advertisers don't discover these until they've wasted 30-50% of their budget. An experienced manager turns them off on day one.

Frequently Asked Questions
UK agency fees typically range from £500-2,000/month for management, plus ad spend. Some charge a percentage of spend (10-20%). At the lower end, you're getting junior account managers. At the higher end, you get senior strategists with direct account access.
Yes, technically. But 'can' and 'should' are different questions. If your budget is under £2k/month, you might not be able to afford agency fees. If it's over £5k/month, the cost of your own learning mistakes probably exceeds agency fees.
Leaving LinkedIn's default settings enabled. Audience Expansion, LinkedIn Audience Network, and Maximum Delivery bidding are all turned ON by default. They benefit LinkedIn's revenue, not yours. Most DIY advertisers don't discover this until they've wasted 30-50% of their budget.
Ask them for CPQP (Cost Per Qualified Pipeline), not just CPL. If they can't tell you how many leads became sales conversations, they're optimising for vanity metrics. Also: are they proactively suggesting creative tests, or just running the same ads for months?
Good freelancers can be excellent value: senior expertise at lower overhead. The risk is availability and continuity. If they get sick or busy, your campaigns suffer. Agencies provide backup coverage. Choose based on your risk tolerance and budget.
