How Much Does Google PPC Cost for a Small Business in the UK?

Google PPC is one of the fastest ways for a UK small business to generate leads. But the first question every business owner asks is the same: how much is this going to cost me? The honest answer is that it depends on your industry, your location, and how competitive your market is – but there are clear benchmarks that can help you plan.

At Lead Gems, we manage PPC campaigns for businesses across professional services, healthcare, trades, and more. Here’s what we see in practice, and how to think about your budget.

What does the average UK business spend on Google PPC?

Most UK small businesses running Google Ads spend between £1,000 and £5,000 per month. That’s not a rule – some spend £500, some spend £20,000 – but the £1k–£5k range is where most small and medium businesses land when they’re serious about generating leads rather than just testing the water.

The cost per click (CPC) in the UK varies enormously by sector. Legal services typically see CPCs of £5–£15. Trades like plumbing or electrical sit around £2–£8. Financial services can reach £10–£30 for competitive terms. Dental practices usually fall in the £3–£10 range.

What affects your Google PPC costs?

Four factors drive your cost per click and overall spend:

• Industry competition – the more businesses bidding on the same keywords, the higher the cost per click
• Geographic targeting – targeting London or Manchester costs more than targeting a smaller town because there are more competitors
• Keyword intent – high-intent searches like “solicitor near me” cost more than informational searches like “do I need a solicitor”
• Quality Score – Google rewards well-structured campaigns with lower CPCs. Poor landing pages and irrelevant ads drive costs up

How much should a lead cost from Google PPC?

Cost per lead (CPL) is what actually matters – not cost per click. A £10 click that converts at 10% gives you a £100 lead. A £3 click that converts at 2% gives you a £150 lead. The expensive click was actually cheaper.

Across our campaigns at Lead Gems, typical cost-per-lead ranges for UK businesses are:

• Solicitors and law firms: £40–£120 per lead
• Financial advisers: £60–£150 per lead
• Dental practices: £15–£45 per lead
• Trades (plumbing, electrical, building): £15–£50 per lead
• Accountants: £30–£80 per lead

How do you know if your PPC is working?

The only metric that matters is return on investment. If you’re spending £2,000 per month and generating £20,000 in new revenue, your PPC is working. If you’re spending £2,000 and can’t point to a single new client, something is broken.

At Lead Gems, every campaign has clear tracking from ad click to lead to client. We report on cost per lead, conversion rate, and pipeline value – not impressions or click-through rates. Those vanity metrics don’t pay your bills.

Should you manage PPC yourself or hire an agency?

Google Ads is deceptively simple to set up and genuinely difficult to run well. The difference between a well-managed campaign and a DIY effort can be 3–5x in cost per lead. A professional PPC manager will structure your campaigns properly, write ads that convert, build landing pages that capture leads, and continuously optimise based on data.

The cost of professional PPC management in the UK typically ranges from £500 to £2,000 per month depending on ad spend and complexity. That fee should pay for itself many times over in lower CPCs, higher conversion rates, and more leads.

Getting started with Google PPC

If you’re considering PPC for the first time, start with a focused campaign targeting your highest-value service in your core geographic area. Don’t try to advertise everything everywhere – that’s how budgets get wasted. A tightly targeted campaign with a clear landing page and a strong offer will outperform a broad, unfocused one every time.

At Lead Gems, we build PPC campaigns for UK businesses across professional services, healthcare, and trades. If you want to understand what PPC could deliver for your business, book a free growth call and we’ll give you a realistic projection based on your sector and budget.
