What Each Option Actually Involves
Choosing between a Google Ads consultant and an in-house PPC hire is one of those decisions that sounds simpler than it is. Both routes can work. Both can also go badly wrong if you pick the wrong one for your situation. The difference comes down to what you actually need, how much you can spend, and how much control you want over your campaigns day to day.
An in-house hire means recruiting someone, whether a junior PPC executive or a more senior paid media manager, to sit within your team and manage your Google Ads account full-time. They attend your meetings, understand your business deeply, and are available whenever you need them. The trade-off is that they cost more in real terms than most people budget for, and a single person can only know so much.
A Google Ads consultant, by contrast, is a specialist who works across multiple client accounts. They typically know the platform inside out because they live in it every day. You pay for their time and expertise rather than a salary, and you can scale the relationship up or down without the complications of employment law. The relationship is more transactional, but that is not always a bad thing.
“Most Google Ads accounts I audit haemorrhage cash on search terms the business owner has never even looked at. That's not a technology problem - it's an attention problem. My job is to care about your budget as much as you do, and apply the kind of scrutiny that only comes by thinking it's my money.” — John Russell, Director, Digital Womble
The Real Costs: Consultant Fees vs Employing Someone
Most businesses underestimate what an in-house hire actually costs. A mid-level PPC manager in the UK earns somewhere between £28,000 and £45,000 per year in salary alone. Add employer National Insurance contributions, pension contributions, holiday pay, equipment, software licences, and any training costs, and the real annual cost sits closer to £40,000 to £60,000 before you have spent a single penny on actual ad spend.
Google's negative-keyword guidance reinforces the principle: paid-search optimisation is about excluding irrelevant intent as well as finding demand. Judge changes on query relevance, conversion quality and commercial outcome—not clicks in isolation.
A Google Ads consultant typically charges either a monthly retainer or a percentage of ad spend. Monthly retainers for a specialist working with small and medium-sized businesses commonly range from around £500 to £2,500 per month depending on account complexity and the scope of work involved. For many SMEs running modest campaigns, a consultant costing £12,000 to £18,000 per year covers far more ground than a junior in-house hire at the same price point, and without the overhead.
There is also the question of what happens when results stall. With a consultant, you can change tack, request a fresh approach, or part ways without redundancy risk. With an in-house hire, underperformance is a much more complicated and costly problem to resolve. If you want a clearer breakdown of what external management actually costs, the Google Ads management services pricing guide covers the typical fee structures in detail. If the issue is whether an existing account is wasting spend rather than who should manage it long term, a £395 Google Ads Account Review gives you a focused starting point before committing to broader management.
Where an In-House Team Has the Edge
An in-house PPC manager knows your business better than any external consultant ever will, at least in the early months. They attend product launches, sit in on sales calls, and absorb the institutional knowledge that never quite makes it into a briefing document. For businesses where campaigns need to react very quickly to stock levels, seasonal shifts, or pricing changes, having someone in the building is genuinely useful.
There is also a collaboration advantage. An in-house person can work closely with your wider marketing team, aligning paid search with organic content, email campaigns, and social activity without the friction of briefing an external party every time something changes. For larger organisations with complex, multi-channel activity, that internal alignment has real value.
And if your business runs Google Ads as a core growth channel with a significant monthly budget, say £20,000 or more per month in ad spend, full-time internal resource starts to make more financial sense. The complexity and volume of work at that scale can justify the overhead, and the business knowledge an in-house manager builds over time becomes a genuine competitive asset.
Where a Google Ads Consultant Wins
For most small and medium-sized businesses in the UK, a Google Ads consultant wins on value almost every time. You get access to someone who has managed dozens, sometimes hundreds, of accounts across different industries. They have seen what works and what does not, and they bring that pattern recognition to your campaigns from day one rather than spending six months learning the ropes.
Consultants also tend to stay sharper on platform changes. Google updates its ad products constantly, from smart bidding updates to new campaign types to changes in match type behaviour. A consultant who works across multiple accounts has a commercial incentive to stay current. An in-house hire managing a single account often does not get that same breadth of exposure, and training budgets rarely cover it adequately.
Speed is another factor. A good consultant can audit an existing account, identify wasted spend, and make meaningful improvements within weeks rather than months. If your campaigns are currently underperforming and you are under pressure to show results, waiting three months for a new hire to clear notice, onboard, and find their feet is not always an option. For guidance on what a consultant should actually do for you, the article on what does a Google Ads consultant do is worth reading before you make any decisions.
If you want evidence rather than promises, review the measured Google Ads results and the local-service revenue case study to see how search-term control, spend efficiency and conversion performance have been measured in real accounts.
The Hybrid Approach: A Middle Ground Worth Considering
Some businesses get the best of both options by using a blended model. A junior in-house executive handles day-to-day account management, reporting, and reactive tasks, while an external consultant provides strategic oversight, quarterly reviews, and specialist support when campaigns need restructuring or scaling. This setup gives you internal responsiveness without sacrificing specialist expertise.
This approach works particularly well for marketing managers at growing businesses who have some internal capacity but lack a genuine PPC specialist on the team. Tom, a marketing manager at a regional business in Manchester, might have a general digital marketing executive in-house but no one with deep Google Ads experience. Bringing in a consultant on a lighter retainer for strategic guidance fills that gap without the cost of a full-time specialist hire.
The hybrid model also reduces dependency risk. If your sole in-house PPC person leaves, your account does not grind to a halt because there is an external specialist who already knows the account. And if the consultant relationship ends, you still have internal continuity. It is not the right model for every business, but it is worth considering before you commit to either extreme.
How to Make the Right Call for Your Business
The honest answer is that there is no universal right choice between a Google Ads consultant and an in-house hire. The right answer depends on your monthly ad spend, how quickly you need results, your internal team structure, and your budget for management overhead. If your ad spend is below £10,000 per month, a consultant almost always represents better value. If you are spending significantly more and need daily operational management, an in-house hire starts to make sense.
Before you decide, be clear about what you actually need from a PPC manager. If you need someone to attend weekly team meetings, react to hourly changes, and integrate tightly with your sales team, an in-house hire fits that brief. If you need expert campaign strategy, solid account structure, and measurable improvements in return on ad spend, a consultant is usually the faster and more cost-effective route.
The broader article on Google Ads consultant work, costs and whether you need one is a good starting point if you are still weighing up the options. Take an honest look at your budget, your current campaign performance, and what the gap actually is between where you are and where you need to be. That gap will tell you more than any comparison article can.
