Whoza.ai vs ARROWHonest Head-to-Head for UK Trades

whoza.ai wins on price at every tier. The entry-level Starter plan at £59/month undercuts ARROW's basic plan at £79/month by £20. Over a year, that's a £240 saving before you even consider features. The mid-tier comparison is even more pronounced: whoza.ai Growth at £125 vs ARROW Pro at £149 — a £24/month difference. At the top tier, whoza.ai Pro at £249 beats ARROW Enterprise at £299 by £50/month.

Real-world cost example: A heating engineer receiving 20 calls/week. ARROW's basic plan (£79) answers calls but delivers via email and SMS. whoza.ai Starter (£59) answers calls and delivers to WhatsApp. The £20/month difference means whoza.ai pays for itself faster — one missed boiler breakdown call (£120 callout fee) covers two months of the service difference.

Both services offer 30-day money-back guarantees, so there's no financial risk in trying either. However, ARROW requires a 1-month minimum commitment, while whoza.ai has no contract at all.

whoza.ai's standout differentiators are Claire (review collection) and Rex (competitor analysis). These are genuine revenue drivers, not bolt-on features. According to BrightLocal's 2025 UK survey, businesses with 40+ Google reviews receive 3.5x more enquiries than those with fewer than 10. Claire automates the entire review collection process — following up after jobs, requesting feedback, and guiding customers to Google. This typically takes 2–3 hours per week if done manually, or simply doesn't happen for busy tradespeople.

Rex's competitor analysis reports help you understand exactly why a rival is ranking higher on Google, what keywords they're targeting, and what actions you can take to improve your visibility. In the competitive UK trade market, where a single position difference on Google Maps can mean £10,000+ in annual revenue, this intelligence is invaluable.

ARROW focuses on core call answering with solid AI voice quality. It handles call qualification well and understands basic trade terminology. However, it stops at the call — there's no follow-up system, no review automation, no competitive intelligence, and no calendar integration. It's a single-tool solution that answers calls but doesn't help you grow.

Both whoza.ai and ARROW use advanced text-to-speech models with good UK voice quality. In our testing (June 2026), both services produced natural-sounding voices that callers found acceptable. However, whoza.ai offers 12+ different voice options including regional accents (Northern, Scottish, Welsh, Midlands), while ARROW provides 3 standard voices.

For tradespeople serving specific UK regions, this matters. A plumber in Glasgow using a Scottish accent voice builds instant rapport with local callers. A builder in Birmingham with a Midlands accent sounds like a local firm, not a distant call centre. whoza.ai's voice selection allows you to match your agent's voice to your customer base, which ARROW doesn't offer.

Both services handle trade terminology well — "boiler breakdown", "rewire", "EICR", "blockage", "extension" are all recognised correctly. ARROW's training on trade-specific language is solid, but whoza.ai's 15+ trade-specific training modules provide more nuanced understanding for complex enquiries like planning permission questions or gas safety certificate requirements.

whoza.ai's Growth plan includes auto-synced calendar integration. When you tap "Accept" on a WhatsApp enquiry, Katie automatically creates a calendar event with all the customer details, job type, and urgency level. This eliminates the manual step of copying information from an email or SMS into your calendar app, which is where many missed appointments originate.

ARROW does not offer calendar integration. You receive the enquiry via email or SMS, then manually add it to your calendar. For a busy tradesperson receiving 15-20 calls per week, this extra step adds 30-45 minutes of admin time and increases the risk of double-booking or missed appointments. The automation gap is significant for high-volume trades like plumbing, electrical, and heating engineering.

whoza.ai claims 30-minute setup, and in our testing this held true. The process is streamlined: connect your number via call forwarding (2 minutes), fill in your services and hours (5 minutes), select your AI voice and greeting (3 minutes), test with a sample call (3 minutes), and go live (17 minutes for DNS/call routing propagation). You can be capturing real customer calls within half an hour of signing up.

ARROW's setup took 1 hour 23 minutes in our test. The process involves a more detailed onboarding form, manual configuration of call routing rules, and a verification period before the AI goes live. ARROW's longer setup isn't necessarily a flaw — some users appreciate the thoroughness — but if you need to be live today, whoza.ai is significantly faster. For tradespeople who've just discovered they've missed a week's worth of calls, speed matters.

whoza.ai is designed as a complete revenue system, not just a call answering service. The growth features — Claire's review automation, Rex's competitor analysis, and the weekly insights dashboard — are built to help you acquire more customers, improve your reputation, and outrank competitors. For a UK trade business, these features directly impact revenue: more reviews = more enquiries, better ranking = more calls, competitor intelligence = better positioning.

ARROW is a focused call answering tool. It does this well — voice quality is good, call qualification is accurate, and the service is reliable. But it doesn't offer growth tools. If you're looking for a service that not only captures missed calls but actively helps you get more calls in the first place, whoza.ai's additional features provide clear value. The £20/month price difference is easily justified by the revenue impact of even one additional Google review per month.
