5 Best Free CRM Software for UK Businesses (2025)
Running a startup or small business? You don't need to spend a fortune. We tested the best CRMs that offer generous "Free Forever" plans.
What to look for in a Free CRM?
Not all "Free" plans are created equal. Some are just 14-day trials in disguise. For this list, we only selected software that meets these criteria:
- Truly Free Forever: No time limits.
- Reasonable Limits: Must allow at least 500 contacts.
- UK Compliance: Must be GDPR compliant.
HubSpot CRM
Best User Experience
Why it's #1
HubSpot is the gold standard for a reason. Their free plan is incredibly generous. You can store up to 1,000,000 contacts, invite unlimited users, and track your sales pipeline without paying a penny.
The interface is beautiful and intuitive. It connects effortlessly with Gmail and Outlook, automatically logging your emails. If you just need a place to store data and track deals, HubSpot Free is unbeatable.
The Catch: Marketing automation (e.g., automated email sequences) is NOT included. To get that, you have to upgrade to the £800/mo Professional plan.
-
Pros
- Unlimited Users & 1M Contacts
- Best-in-class interface
- Includes free landing pages & forms
- Great mobile app
-
Cons
- No automation features on free plan
- Upgrades are very expensive
Systeme.io
Best for MarketingWhy it's great
If HubSpot is the best Sales CRM, Systeme.io is the best Marketing CRM. Their free plan is shocking: it includes 2,000 contacts, unlimited email sending, 3 sales funnels, and 1 course website.
Unlike HubSpot, Systeme includes email automation in the free plan. If you are a course creator or a coach starting out, this is the best option.
-
Pros
- Includes Email Automation & Funnels
- Host 1 Course for free
- Stripe/PayPal integration included
-
Cons
- CRM pipeline is very basic
- Page builder can be glitchy
Zoho CRM
Best for Data Geeks
The Verdict
Zoho offers a "Free Edition" for up to 3 users. It is packed with features that usually cost money, like workflow rules and custom document views.
It is a powerful database tool, but the interface feels outdated (like Windows 95). If you don't mind a steep learning curve, you get a lot of power for £0.
-
Pros
- Deep customization options
- Good for B2B data tracking
- Includes mobile app
-
Cons
- Limited to 3 users only
- No mass email feature in free version
Monday.com
Best for Students/Solos
The Verdict
Monday.com has a free plan, but it is limited to 2 users. It is fantastic if you want a visual way to track leads using their "Board" view. It feels more like a colorful spreadsheet than a heavy database.
However, the free plan is very restricted. You cannot use automations or integrations, which limits its use for scaling businesses.
-
Pros
- Fun, colorful interface
- Great Android/iOS apps
- Good for simple task management
-
Cons
- 2 User limit
- No automations on free plan
Bitrix24
Best Unlimited OptionThe Verdict
Bitrix24 is unique because it offers a free plan with Unlimited Users. It includes a CRM, website builder, and even an internal team chat (like Slack).
The downside? It is incredibly cluttered and confusing to use. It tries to do everything, which means it doesn't do any one thing particularly well. But for a large team with zero budget, it works.
-
Pros
- Unlimited Users for free
- Includes Team Chat & Video calls
- 5GB Online Storage included
-
Cons
- Very confusing interface
- Steep learning curve
