AI personal assistant costs for UK businesses in 2026 range from £0 to over £2,000 per month, depending on the scope of functionality, the level of customisation, and whether the system includes voice call handling. Most UK SMEs pay between £99 and £500 per month for a configured AI PA that meaningfully reduces admin time. This guide breaks down every pricing tier, what each level includes, the hidden costs that catch businesses by surprise, and a five-year comparison against human PA costs.
The short answer: £0 for basic AI drafting tools with no business integration, £99 to £299 for SME-focused AI PA platforms with call handling, and £500 to £2,000+ per month for enterprise-grade deployments with custom integrations, regulatory compliance logging, and dedicated account management. Softomate's AI PA for UK service businesses starts at £299 per month, inclusive of 24/7 call handling, appointment booking, lead capture, WhatsApp notifications, and monthly performance reporting.
Against the human alternative: a part-time human PA in London costs £14,000 to £20,000 per year (£1,167 to £1,667/month). A full-time human PA costs £28,000 to £40,000 per year (£2,333 to £3,333/month). A virtual human PA charges £10 to £35 per hour with no availability outside contracted hours. An AI PA at £299/month provides 24/7 coverage at 13% to 25% of the cost of a part-time human PA.
The Google UK pilot study tracking AI admin tool adoption found that UK workers save an average of 122 hours per year using AI tools for administrative tasks. For a business owner or sole trader whose effective hourly rate is £75 to £150, 122 saved hours represents £9,150 to £18,300 in recovered time value annually - against an AI PA cost of £3,588 per year at the £299/month tier.

Several AI tools are available at no cost that provide useful AI assistance for UK business owners. Understanding what free tools actually include - and exclude - is essential for making an informed comparison.
Microsoft Copilot (free tier). Available to all Windows 11 users and via web browser. Provides AI chat, document drafting, and basic image generation. Does not integrate with business email or calendar without a Microsoft 365 subscription. Cannot handle inbound calls. Requires manual prompting for every task - it does not operate autonomously. Suitable as a drafting aid; not a PA replacement.
Google Gemini (free tier). Available via Google account. Similar to Copilot: strong AI chat and drafting capability, limited business system integration without a Google Workspace subscription, no call handling, no autonomous operation. Useful for ad hoc tasks.
ChatGPT free tier. GPT-4o mini capability at no cost. Excellent for drafting, summarising, and answering questions. No integration with business systems. No call handling. No autonomy. Requires manual use for every task.
Otter.ai free tier. Meeting transcription for up to 300 minutes per month. Useful for sole traders attending a small number of meetings. The paid tier (from around £8.33/month billed annually) adds unlimited transcription, automated meeting summaries, and CRM integrations.
Calendly free tier. Scheduling link for one event type. Removes the scheduling friction for straightforward one-type appointment businesses. The paid tier (from around £8/month) adds multiple event types, team scheduling, CRM integrations, and automated reminder emails.
The honest assessment of free tools: they are useful AI utilities, not AI personal assistants. They provide AI capability when you manually engage with them. They do not answer your phone when you are on-site, automatically update your CRM after a client call, or send a WhatsApp notification when a new enquiry arrives at 8pm. The distinction between AI utility and AI assistant is the presence of autonomous, always-on operation integrated with your business systems.
The table below maps the UK AI PA market across five pricing tiers, from entry-level productivity tools to enterprise deployments.
| Tier | Monthly Cost | Annual Cost | What Is Included | Best For |
|---|---|---|---|---|
| Free | £0 | £0 | AI chat and drafting (manual use only); no business system integration; no call handling; no autonomy | Sole traders who want AI assistance for writing tasks only |
| Basic | £9.99-£99 | £120-£1,188 | Point solutions: meeting transcription (Otter.ai), scheduling links (Calendly), inbox triage (SaneBox), basic CRM AI. No integrated call handling. Limited autonomy. | Businesses with a single specific admin bottleneck to solve |
| SME AI PA | £99-£299 | £1,188-£3,588 | Integrated AI PA platform: call handling during business hours or extended hours, appointment booking, email triage, basic CRM integration, lead capture, monthly reporting | Service businesses with 15-50 inbound calls/week wanting AI call coverage and admin automation |
| Full AI PA | £299-£500 | £3,588-£6,000 | 24/7 call handling, appointment booking, lead qualification, CRM updates, email drafting, scheduling automation, WhatsApp/SMS notifications, monthly performance report, onboarding included. Softomate AI PA starts at £299/month. | Owner-operated service businesses, clinics, trades, estate agents - any business where missing a call means losing a client |
| Enterprise | £500-£2,000+ | £6,000-£24,000+ | Multi-site or multi-department call handling, custom call scripts and compliance logging, regulatory call recording, deep CRM and ERP integration, dedicated account manager, SLA-backed uptime, custom reporting dashboard | Multi-location businesses, regulated sectors (healthcare, legal, financial services), businesses with 100+ calls/week |
The SME AI PA tier at £99 to £299/month covers the majority of UK service business needs. The jump to the Full AI PA tier at £299 to £500/month typically reflects the addition of 24/7 coverage (including evenings and weekends) and more sophisticated lead qualification scripts. The Enterprise tier adds regulatory compliance, multi-site capability, and dedicated account management.
One important caveat: some platforms advertise low entry prices but charge per call or per minute, meaning a business with high call volume finds its monthly cost significantly higher than the headline rate. Always ask whether the pricing is per-call or unlimited before committing to a platform.
The right AI PA tier depends significantly on your business type and call volume. Here is how the cost maps across the most common UK SME categories:
Sole trader or freelancer (under 10 calls/week). The Basic tier (£9.99-£99/month) is typically sufficient. Priorities: scheduling automation (Calendly paid, ~£8/month), meeting transcription (Otter.ai, ~£8.33/month), and inbox triage (SaneBox, ~£7/month). Total: £23-£30/month for a meaningful reduction in admin time. Call handling at this volume may not justify the Full AI PA tier cost unless missed calls are a specific revenue risk.
Small service business (10-30 calls/week, 1-5 employees). The SME AI PA tier (£99-£299/month) is appropriate. At 20 calls/week, even 20% going unanswered means 4 missed calls per week. At BT Business's average call value of £1,200, that is £4,800/week in potential missed pipeline. An AI PA at £299/month that recovers 80% of those missed calls generates substantially more value than its cost. The Sage UK 2025 research found 90% of UK SME AI adopters reporting productivity gains - this business size is the primary beneficiary.
Growing service business (30-80 calls/week, 5-20 employees). The Full AI PA tier (£299-£500/month) is the standard recommendation. At this call volume, 24/7 coverage becomes commercially critical: callers who ring at 7pm or on Saturday morning are often among the most motivated buyers. Missing them disproportionately costs revenue. The Answer4u research quantifying UK missed-call losses at £30 billion annually is largely driven by businesses in this bracket - high enough call volume to generate significant losses, but not yet resourced with dedicated reception teams.
Multi-location or regulated business (80+ calls/week). Enterprise tier (£500+/month). Custom call routing across locations, compliance-grade call recording, regulatory script enforcement, and dedicated account management are necessary at this scale. The per-site call handling costs are often lower than the SME tier on a per-call basis, but the setup and integration investment is higher.
The headline monthly price of an AI PA product rarely tells the whole story. UK businesses deploying AI PA tools commonly encounter these additional costs:
Setup fees. Some AI PA providers charge a one-time setup fee of £200 to £1,000 to cover call script development, system configuration, and integration testing. Softomate includes setup in the monthly fee. Always clarify whether setup is included before signing a contract.
Per-call or per-minute charges. Entry-level AI voice agent platforms often charge per minute of call handling rather than a flat monthly rate. At 30 inbound calls per week averaging 3 minutes each, that is 90 minutes per week or 360 minutes per month. At £0.10/minute (a common rate), that is £36/month - which sounds cheap until call volume spikes during a marketing campaign and the bill doubles or triples.
Integration costs. Connecting an AI PA to your CRM (Salesforce, HubSpot, Pipedrive, GoHighLevel), accounting software (Xero, QuickBooks), or practice management system often requires either a native integration (free, if available) or a custom API connection (£500 to £2,000 one-time development cost). Always confirm which integrations are native and which require custom development before purchase.
Phone number costs. If you want a new UK business number (rather than forwarding your existing number), a VoIP business number typically costs £2 to £15/month depending on the number type (geographic, 0800, 0345). Most AI PA providers offer number portability for your existing business number at no additional cost.
Overage charges. Some plans cap the number of calls, messages, or AI interactions per month. Exceeding the cap triggers overage charges. For businesses with seasonal call spikes - a plumber in January, a garden centre in spring - this can generate unexpected costs. Look for unlimited-call plans or plans with high caps that accommodate your peak volume.
Annual vs monthly billing. Most AI PA providers offer a 10 to 20% discount for annual billing versus monthly billing. At £299/month on a monthly contract, switching to an annual contract at £249/month saves £600 over the year. If you are confident in the product after a 60-day trial, annual billing is almost always the better financial decision.
The 12-month cost comparison is useful; the five-year view is more revealing for businesses making a strategic infrastructure decision.
Scenario: UK service business with 40 inbound calls/week, five-year horizon.
Option A: Full-time in-house PA or receptionist
Option B: Part-time human PA (20 hours/week)
Option C: Softomate AI PA (£299/month, current pricing)
Option D: Hybrid (Softomate AI PA + 15 hours/month VA)
The five-year view makes the cost case for AI PA unmistakably clear. The savings are not marginal - they are structural. Even the hybrid model that combines AI PA with a human virtual assistant saves £140,000 or more over five years compared to a full-time in-house administrator. For a service business reinvesting that saving into growth, marketing, or product development, the compounding effect is significant.

Before committing to any AI PA product, run a simple ROI calculation using your own business data. This takes 15 minutes and prevents you from either over-investing in a tier you do not need or under-investing in a tool that could transform your call handling.
Step 1: Count your current monthly inbound calls. Check your phone system log, BT call manager, or ask your current service provider for a monthly call report. If you do not have call data, count calls manually for one week and multiply by four.
Step 2: Estimate your missed call rate. The paperclip.co.uk 2025 study of 142 UK SMEs found 27-47% of calls going unanswered. If you are unsure, use 35% as a conservative estimate. Multiply your monthly call volume by 0.35 to get estimated missed calls per month.
Step 3: Calculate the value of missed calls. BT Business research puts the average UK business call value at £1,200. For your business, estimate the average revenue generated by a successful client conversion. Multiply by your average conversion rate from enquiry to sale. For example: 30 missed calls/month x 20% conversion rate x £800 average job value = £4,800/month in missed pipeline.
Step 4: Estimate your admin time cost. The Google UK pilot study found AI admin tools save 122 hours per year. For your own estimate: log your admin time for one week (calls, email, scheduling, CRM updates). Multiply by 52 to get annual hours. Multiply by your effective hourly rate to get the annual cost of that admin time. A business owner spending 10 hours/week on admin at £100/hour is spending £52,000/year in time cost.
Step 5: Compare against AI PA cost. Softomate's AI PA at £299/month = £3,588/year. If your missed-call value is £4,800/month and your admin time cost is £2,000/month, the total addressable saving is £6,800/month. Even recovering 50% of that saving generates £3,400/month against a £299/month investment - an 11:1 return.
Step 6: Use the break-even check. If your estimated monthly value from missed call recovery plus admin time saving is at least three times the monthly AI PA cost, the ROI case is strong. If it is below three times the cost, consider the Basic tier rather than the Full AI PA tier, or focus on a single point solution (scheduling only, for example) before committing to a full AI PA deployment.

The cheapest functional AI personal assistant for UK small businesses depends on what you need it to do. For AI drafting and question-answering only: Microsoft Copilot (free with Windows 11) and ChatGPT (free tier) cost nothing. For scheduling specifically: Calendly free tier handles one event type at no cost. For meeting transcription: Otter.ai free tier provides 300 minutes/month. For 24/7 AI call handling - the highest-value capability for most service businesses - the minimum realistic cost is £99 to £299/month.
Microsoft Copilot has both a free tier and a paid tier. The free version is available to Windows 11 users and via the Copilot website, providing AI chat and drafting capability at no cost. The paid version - Microsoft 365 Copilot, previously called Microsoft Copilot for Microsoft 365 - costs from £24.70 per user per month (as of early 2026) and integrates deeply with Outlook, Teams, Word, and Excel.
Softomate's AI PA for UK service businesses starts at £299 per month. This includes 24/7 inbound call handling, appointment booking, lead qualification, WhatsApp notifications for new enquiries, CRM integration, and a monthly performance report. Setup is included in the monthly fee with no separate onboarding charge. The £299/month tier covers unlimited calls within the agreed call volume band. For businesses requiring custom integrations, multi-site call handling, or regulatory compliance logging, bespoke pricing applies.
Setup fees vary significantly by provider. Some AI PA platforms charge £200 to £1,000 as a one-time onboarding fee covering script development, system configuration, and integration testing. Softomate includes setup in the monthly subscription - there is no separate setup charge. When comparing AI PA providers, always ask explicitly whether setup, onboarding, and integration work is included in the headline monthly price or billed separately.
Yes, in most cases significantly so. A human PA in London costs £14,000 to £40,000 per year depending on hours and seniority. A Softomate AI PA costs £3,588 per year and is available 24 hours a day, seven days a week. The savings over five years compared to a full-time human PA are typically £140,000 to £200,000.
Before committing to any AI PA tier, run a simple calculation using your own numbers. Take your current monthly call volume and multiply the miss rate by your average job or transaction value. Then multiply the admin hours you spend each week by your effective hourly rate. Add those two figures together - that is your current monthly cost of not having an AI PA. Compare it to the subscription tier that addresses your primary constraint. For most UK service businesses, the calculation shows a payback period of under two weeks at the SME tier. For businesses where call volume is the primary driver, the payback is often measured in days, not weeks.
