If you search for "hubspot vs mailchimp uk" you mostly find affiliate roundups written for an American audience. This guide takes a different approach. Prices below come from the vendors' own pricing pages, and vendor pricing changes often, so treat them as a guide and check before you buy. The comparison is framed around how UK small businesses actually buy, with VAT, GBP budgets and a market where, according to the gov.uk Business Population Estimates, there are around 5.5 million private sector businesses and the overwhelming majority are small.
What is the real difference between HubSpot and Mailchimp?
In practice this means the comparison is rarely a straight swap. A cafe sending a monthly newsletter and a surveying firm nursing 40 quotes through a three month pipeline are buying different things, even if both type the same search into Google. Before comparing features, decide which product category you are actually in. The UK CRM buyer's guide covers that decision in more depth if you are not sure.
How much does HubSpot cost for a UK small business?
The numbers worth dwelling on are the ones at the Professional boundary. According to HubSpot's pricing page, Starter includes 1,000 marketing contacts, Professional costs more if you bill monthly rather than annually, and Enterprise sits at $3,600 a month with a larger required onboarding fee. For most UK small businesses the honest summary is that HubSpot Free and Starter are affordable, and Professional is a five figure annual commitment once fees and extra contacts are counted. The jump between those tiers is the single biggest complaint experienced HubSpot users raise, and it is worth planning for before you build your business on the platform.
How much does Mailchimp cost, and where do prices climb?
Mailchimp's pricing looks gentle until your list grows, because every paid plan is tiered by contact count. The prices above are entry points for small lists, and Mailchimp's pricing page shows contact tiers stretching far beyond small-list pricing on Standard. Two details catch UK buyers out. First, Mailchimp has historically counted unsubscribed and non-subscribed contacts towards your total on some configurations, so check how your audience is counted, because an unclean list can inflate your bill. Second, send limits scale with your contact count, which is generous for newsletters but worth checking against the current pricing page if you run frequent automated flows.
Which platform is better for pure email marketing?
Mailchimp's Essentials plan includes A/B testing and scheduling, and Standard adds custom templates and its automation builder. If your entire ambition is a well designed fortnightly email to customers, Mailchimp gets you there faster with less to configure. Where HubSpot pulls ahead is personalisation depth. Because every email can draw on full CRM data, deal stage, owner, lifecycle stage, past conversations, HubSpot emails can be targeted in ways Mailchimp's tag-and-segment model finds awkward. Our guide to email marketing for UK small businesses covers the strategy side regardless of which tool you pick.
Which is better as a CRM?
This is the question that should decide the whole comparison for service businesses. A plumber, an accountant, a lettings agent or an agency selling projects worth hundreds or thousands of pounds needs to know where each opportunity stands, who spoke to the prospect last, and what happens next. HubSpot models that natively, free of charge. Trying to force that workflow into Mailchimp means spreadsheets on the side, and spreadsheets on the side are where follow-ups go to die. Choosing and wiring up this layer properly is exactly the kind of work covered on the email and CRM systems service page.
Which has the better automation?
The practical question is whether your automations need to touch anything other than email. If a flow is "person joins list, receives five emails over three weeks", both tools handle it comfortably and Mailchimp is cheaper. If a flow is "enquiry arrives, gets assigned to whoever is on rota, a task is created, and a follow-up email goes out only if no one calls within two days", that is HubSpot territory, and mostly paid HubSpot territory. Sketch your three most valuable flows on paper before buying, a habit explained in the guide to email automation flows for UK businesses, and the right platform usually becomes obvious.
How do the two handle UK GDPR and consent?
There are still practical differences. HubSpot's lawful basis tracking is more granular because consent lives on a full contact record alongside everything else you know about the person, which makes subject access requests easier to service. Mailchimp's double opt-in is a simple toggle and its signup forms handle consent language cleanly. For a UK business the sensible baseline on either platform is the same, double opt-in for new signups, separate consent for marketing versus transactional messages, and a written note of where each imported list came from.
When should you pick Mailchimp?
Mailchimp also wins when the person running marketing is a non-specialist owner with two spare hours a week. There is simply less surface area to learn, and the entry price on Mailchimp's pricing page is a fraction of HubSpot Professional. The trade-off you are accepting is a ceiling. When you eventually want sales pipeline, lead rotation or reporting that connects email to revenue, you will be adding a second tool or migrating.
When should you pick HubSpot?
HubSpot is also the safer choice if you expect to hire. A CRM that a new salesperson can log into on day one, with every past conversation attached to every contact, is worth more than any individual feature. The discipline required is financial, not technical. Write down, before you sign up, what evidence would justify the Professional upgrade, because HubSpot's product is very good at making that upgrade feel inevitable whether or not the numbers support it.
Can you run both together?
If you go this route, make one system the master record for contacts and sync one way where possible. Review the setup every six months, because the dual-tool phase should be temporary. Once your email programme starts driving measurable revenue, consolidating onto one platform removes the drift, the double unsubscribe risk and one monthly invoice. Which platform you consolidate onto is, by then, usually obvious from where the value showed up.
What is the bottom line for UK buyers?
Whichever you choose, the platform matters less than the system around it, clean data, honest consent, a handful of automations that actually run, and someone accountable for looking at the numbers monthly. In a market of around 5.5 million private sector businesses, the ones that win with email are rarely the ones with the most expensive software. They are the ones that reply first and follow up every time.
HubSpot vs Mailchimp for UK Small Businesses — FAQ
Is HubSpot or Mailchimp cheaper for a UK small business?
At small list sizes, Mailchimp is usually cheaper for email. Its pricing page lists Essentials from $13 a month and Standard from $20 a month, both often shown with an introductory discount for the first 12 months. HubSpot's free CRM costs nothing, and Marketing Hub Starter is listed at around $15 to $20 a month per seat depending on billing terms. The gap appears at the next step up. HubSpot Marketing Hub Professional is listed at $800 a month billed annually, plus a one-time $3,000 onboarding fee, while Mailchimp's top Premium plan is listed at $350 a month. Both vendors display prices in US dollars, so UK buyers should check the checkout currency and remember VAT is added on top.
Does HubSpot have a free plan?
Yes. HubSpot's pricing page includes a free tier that covers the core CRM, contact records, basic email and forms. For many UK small businesses this free CRM is the main reason to start with HubSpot at all, because it gives you a single place to store contacts, deals and conversations without paying anything. The catch is that the free tools carry HubSpot branding, the sending and automation limits are tight, and the product is designed to move you towards paid tiers. Treat the free plan as a genuinely useful starting point for organising your pipeline, but budget for Starter pricing if email volume or automation matters to your business.
Can Mailchimp work as a CRM?
Only in a limited way. Mailchimp stores contacts, tags, segments and purchase activity, and its paid plans support marketing automation and multi-step journeys, which covers a lot of follow-up work. What it lacks is the sales side of a CRM. There is no proper deal pipeline, no meeting scheduling tied to contact records, no quoting, and no shared inbox for a sales conversation that spans weeks. If your business sells through a considered process, quotes, site visits, proposals, then Mailchimp alone will leave you tracking deals in a spreadsheet. If you sell instantly online or take bookings, Mailchimp plus your booking or ecommerce platform is often enough.
How hard is it to switch from Mailchimp to HubSpot?
Moving the list itself is straightforward. You export contacts from Mailchimp as a CSV, import them into HubSpot, and map tags to HubSpot properties or lists. The fiddly parts are everything around the list. Automations have to be rebuilt by hand because the two platforms model journeys differently. Signup forms embedded on your website need replacing. Historical campaign engagement does not transfer in a useful way, so your new platform starts with a blind spot on who your engaged readers are. Plan for a transition period where you keep Mailchimp read-only for reference, rebuild your two or three most valuable automations first, and re-permission any old or cold segments before importing them, which is also the safer position under UK GDPR.
Do HubSpot and Mailchimp comply with UK GDPR?
Both platforms provide the tooling you need to run a compliant email programme, including consent fields, double opt-in options, unsubscribe handling and data processing agreements. Compliance itself, though, is your responsibility, not the software's. UK GDPR and PECR care about how you collected the address, what the person agreed to, and whether you can evidence it. A perfectly configured HubSpot or Mailchimp account sending to a bought list is still a breach. Whichever platform you choose, record the lawful basis for each contact, use double opt-in for new signups where practical, honour unsubscribes immediately, and keep marketing consent separate from transactional messages. Both tools make that easy to set up in an afternoon.
