The Short Version
Worked Example: Hunting for UK Plumbing Keywords
Let’s say you’re targeting 'boiler repair' terms in London. Here’s how the top tools compare with real numbers:
| Tool | Main Keyword | UK Search Volume | Related Suggestion | Volume (UK) |
|---|---|---|---|---|
| KeywordNumbers | boiler repair | 9,900/month | emergency boiler repair | 2,400/month |
| Google Keyword Planner | boiler repair | 10,000/month | boiler servicing | 1,600/month |
| Answer the Public | boiler repair | N/A (ideas only) | boiler repair near me | N/A |
| Ubersuggest | boiler repair | 9,900/month | boiler replacement | 1,300/month |
| Moz Keyword Explorer | boiler repair | 8,800/month | gas boiler repair | 1,200/month |
Notice the pattern? Most tools are in the same ballpark for monthly searches (give or take a few hundred). But only KeywordNumbers and Ubersuggest give you unlimited, actionable keyword suggestions for free — and only KeywordNumbers lets you export the whole lot without a 'please upgrade' popup.
Oh, and if you like your data in imperial as well as metric: 9,900 monthly searches is about 10,800 US monthly searches (for the same keyword in the States). But if you’re optimising for UK, stick to UK figures.
The Pros and Cons of Each Tool (No Fluff)
| Tool | Pros | Cons |
|---|---|---|
| KeywordNumbers | Unlimited, real UK data, exports, no login | Newer tool, fewer 'brand' features |
| Google Keyword Planner | Official data, wide range | Needs AdWords account, ideas limited |
| Answer the Public | Great for content inspiration | Low daily limit, can’t export lists |
| Ubersuggest | Clean UI, SERP analysis | Free plan is tight, nags to upgrade |
| Moz Keyword Explorer | Quality suggestions, SERP insights | Free credits run out quickly |

Questions People Are Actually Asking
What is the most accurate free keyword research tool for UK search?
Most tools use similar baseline data, but for UK-specific accuracy and unlimited searches, KeywordNumbers is tough to beat. Google Keyword Planner is solid for search volumes, but less so for creative suggestions.
Can I get UK search volume data without paying?
Yes. Both KeywordNumbers and Google Keyword Planner offer UK monthly volume without charging. The catch? Google’s figures are sometimes rounded or grouped, while KeywordNumbers gives granular numbers.
Which free tool works best for long-tail keywords in the UK?
KeywordNumbers and Answer the Public both excel with long-tail suggestions — but only KeywordNumbers lets you export full lists and filter by exact UK volume.
Do I need to create an account to use these free keyword tools?
No account needed for KeywordNumbers or Answer the Public (unless you want to upgrade). Google Keyword Planner requires a Google Ads account, even if you’re not running ads.
Are there any free keyword tools that show what’s ranking in the UK right now?
Yes, KeywordNumbers and Ubersuggest both let you peek at the UK SERPs and see who’s actually ranking for your target keywords. Moz Keyword Explorer also offers SERP snapshots, but with tight usage limits.

Most reputable tools, including KeywordNumbers and Google Keyword Planner, update monthly. It’s rare to get real-time data in any free tool.
Can I export the keyword data to CSV for free?
Yes, KeywordNumbers lets you export unlimited results to CSV without signing up. Ubersuggest and Moz allow some exporting, but with limits or after login.
