Perplexity AI is the search engine that answers your question instead of giving you a list of links. For UK businesses spending hours researching suppliers, comparing options, and verifying claims, Perplexity cuts that research time by up to 30% — synthesising information from dozens of sources into structured, cited answers.
But at $20/month (approximately £16) for the Pro plan, is it worth paying for search when Google is free? This review covers what Perplexity actually does, how it compares to Google and ChatGPT for business research, and whether the paid plans justify the cost for UK teams.

Perplexity Pricing for UK Businesses
Perplexity bills in US dollars only — there is no GBP pricing option. UK businesses will see currency conversion fees on top of the listed prices. All approximate GBP figures below assume a rate of $1 = £0.80.
| Plan | Cost (USD) | Approx. GBP | Key Features |
|---|---|---|---|
| Free | $0 | £0 | Limited daily queries, standard models, no Deep Research |
| Pro | $20/month | ~£16/month | Unlimited Pro Search, 20 Deep Research/day, model choice, file uploads |
| Enterprise Pro | $40/seat/month | ~£32/seat/month | 500 research/day, SSO, SOC 2, zero data retention, 15K file uploads |
| Enterprise Max | $325/seat/month | ~£260/seat/month | Unlimited everything, premium models (o3-pro, Opus), priority support |
Annual billing saves 17% — Pro drops to approximately £13/month. Enterprise Pro falls to £27/seat/month. For a 10-person team on Enterprise Pro, annual billing costs approximately £3,200/year vs £3,840 on monthly.
Perplexity dropped its ad-supported model in February 2026 to go subscription-first. This means the free tier is more limited than it was — expect throttling during peak hours and restricted access to advanced features.
What Perplexity Does Well
Perplexity is not a chatbot. It is a research tool that happens to use AI. The distinction matters because it is designed to find, verify, and synthesise information — not to generate creative content or hold conversations.
Pro Search
Pro Search is Perplexity’s core feature. Instead of returning a single answer, it follows up with clarifying questions, breaks complex queries into sub-queries, searches multiple sources, and synthesises a structured response with inline citations. Every claim links back to its source — you can verify anything it tells you in two clicks.
Deep Research
Deep Research goes further — reading and analysing dozens of sources over several minutes to produce comprehensive research reports. For procurement decisions (comparing five payroll providers, for example), Deep Research produces the kind of analysis that would take a junior analyst half a day. Pro users get 20 Deep Research queries per day.
Model Council
Introduced in February 2026, Model Council lets you compare answers from multiple AI models simultaneously — GPT-5.2, Claude Sonnet, Gemini Pro, and others. For important business decisions, getting the same question answered by three different models and comparing their reasoning is genuinely valuable.
Internal Knowledge Search
Upload PDFs, spreadsheets, presentations, and other documents, then search across them alongside web results. Spaces (shared workspaces) let teams build persistent research libraries that Perplexity searches when answering questions. Pro users can upload 50 files per Space (50MB each).
What Perplexity Does Not Do Well
Perplexity is not a replacement for Google in every scenario. It struggles with real-time information (breaking news, live stock prices), local search (finding nearby suppliers or services), and navigational queries (when you just want to find a specific website). Google’s index is larger and more comprehensive for these use cases.
The free tier is increasingly limited since the ad model was dropped. During peak hours, free users report throttling and reduced query allowances. If you plan to use Perplexity regularly for work, the free tier will frustrate you within a week.
Citation quality, while strong (78% accuracy on complex queries in third-party testing), is not perfect. Perplexity heavily cites Reddit (46.7% of top citations) — useful for user experience data but not always authoritative for business decisions. Always verify critical claims against primary sources.
Perplexity vs Google vs ChatGPT for Business Research
| Use Case | Best Tool | Why |
|---|---|---|
| Supplier comparison | Perplexity | Synthesises pricing, reviews, and features from multiple sources with citations |
| Market research | Perplexity | Deep Research analyses dozens of sources into structured reports |
| Quick facts/definitions | Google or Perplexity | Both handle well — Perplexity adds sources |
| Finding a specific website | Navigational queries are Google’s strength | |
| Local suppliers | Google Maps integration is unmatched | |
| Creative writing/drafting | ChatGPT or Claude | Purpose-built for generation, not research |
| Code generation | ChatGPT or Claude | Stronger coding capabilities |
| Verifying a claim | Perplexity | Inline citations make verification instant |
| Breaking news | Real-time indexing is faster |
The practical approach for UK businesses: use Perplexity for research, analysis, and verification tasks where cited sources matter. Use ChatGPT or Claude for content creation, drafting, and coding. Use Google for local search, navigation, and real-time information. For a detailed comparison of the general-purpose assistants, see our ChatGPT vs Claude vs Gemini guide.
Data Privacy and GDPR
Perplexity processes data in the United States. For UK businesses, this means international data transfers governed by the EU-US Data Privacy Framework (DPF) and the UK International Data Transfer Addendum (version B.1.0) from the ICO.
On the free and Pro plans, Perplexity may use your queries to improve its models. Enterprise Pro and above offer zero data retention and contractual guarantees that customer data is never used for model training. Enterprise plans also include SOC 2 Type II certification, SSO, SCIM provisioning, and audit logging.
For UK businesses handling sensitive client data or operating in regulated industries, only the Enterprise tier provides adequate data protection. The Pro plan is suitable for general business research where queries do not contain personal data or commercially sensitive information. For more on how AI tools handle UK data, see our AI agents guide which covers the compliance landscape.
Who Should Use Perplexity
Worth the £16/month Pro subscription: consultants, analysts, procurement teams, marketing researchers, anyone who spends more than 2 hours per week researching topics online. The time savings on Deep Research alone justify the cost for research-heavy roles.
Free tier is sufficient for: occasional research queries, quick fact-checking, trying the platform before committing. But expect limitations during peak hours.
Enterprise Pro (£32/seat/month) makes sense for: teams of 5+ who need shared research workspaces, compliance requirements (SOC 2, zero data retention), or high-volume research (500 Deep Research queries per day per user).
Skip it if: your research needs are met by Google, you primarily need AI for content creation (use ChatGPT or Claude instead), or your budget only stretches to one AI subscription (choose a general-purpose assistant first).
