How Much Does an AI Personal Assistant Cost for UK Businesses?

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.

How Much Does an AI Personal Assistant Cost in the UK? (Quick Answer)

The short answer: £0 for basic AI drafting tools with no business integration, £99 to £299 a month 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.

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. Softomate GHL receptionist setup starts from £2,000, including essential account configuration, one inbound call flow and basic booking. Basic platform access and light support start from £99/month, plus AI, calls, numbers, messages and selected add-ons. Prices exclude VAT. Wider workplace AI starts from £3,500 for a defined Microsoft 365 workflow, with care from £199/month; licences and usage are separate. Combined workflows receive one scoped quotation.

For a business owner or sole trader whose effective hourly rate is £75 to £150, saving even 100 hours a year of admin represents £7,500 to £15,000 in recovered time value annually - against a first-year subtotal from £3,188 for Softomate's GHL receptionist entry package (£2,000 setup plus 12 monthly payments of £99), before usage and VAT.

Free AI Personal Assistant Tools for UK Businesses

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. It is not designed to handle inbound calls, and it works when you prompt it rather than operating autonomously. It is best thought of as a drafting aid rather than a PA replacement.

Google Gemini (free tier). Available via Google account. Gemini offers AI chat and drafting, and deeper business system integration depends on a Google Workspace subscription. Like the other free chat tools, it is not built for call handling or autonomous operation. Useful for ad hoc tasks.

ChatGPT free tier. Available at no cost for drafting, summarising and answering questions. The free tier is designed for manual, chat-based use: it does not answer your phone or run business tasks on its own, so each task starts with you.

Otter.ai free tier. Meeting transcription with a monthly usage allowance. Useful for sole traders attending a small number of meetings. Paid plans add more transcription, automated meeting summaries and CRM integrations; check Otter.ai's current pricing.

Calendly free tier. Simple booking links for straightforward appointment types. Removes the scheduling friction for businesses with one main type of appointment. Paid plans add multiple event types, team scheduling, CRM integrations and automated reminder emails; check Calendly's current pricing.

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.

Paid AI PA Tiers: What Each Level Gets You

The table below maps the UK AI PA market across five pricing tiers, from entry-level productivity tools to enterprise deployments.

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.

AI PA Cost by Business Type

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, meeting transcription and inbox triage, each available from specialist tools on monthly plans. Combined, these point tools usually sit at the lower end of the Basic tier and can meaningfully reduce 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. If each enquiry is worth several hundred pounds, that is a significant amount of potential missed pipeline every week, and an AI PA that recovers most of those calls can generate substantially more value than its cost. This business size is often 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. Businesses in this bracket have high enough call volume to generate significant losses, but are often 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.

Hidden Costs to Budget For

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 to cover call script development, system configuration, and integration testing. Softomate's GHL receptionist package has a setup fee from £2,000 alongside monthly care from £99. 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. Some AI PA providers offer a discount for annual billing versus monthly billing; ask whether one is available before you sign.

AI PA vs Human PA: 5-Year Cost Comparison

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

• Year 1: £28,000-£32,000 salary + 13.8% employer NI + 3% pension = approximately £33,500-£38,500
• Annual salary inflation (3-4% per year): Year 5 salary approximately £32,000-£37,000
• 5-year total (salary + employer costs): approximately £180,000-£210,000
• Coverage: Mon-Fri 9am-5pm; no evenings, weekends, or bank holidays
• Recruitment cost: £2,000-£5,000 per hire (one to two hires over five years)
• 5-year total including recruitment: approximately £185,000-£220,000

Option B: Part-time human PA (20 hours/week)

• Year 1: £14,000-£18,000 + employer costs = approximately £16,000-£21,000
• 5-year total: approximately £85,000-£110,000
• Coverage: limited to contracted hours
• Missed calls outside hours: 40-50% of call volume

Option C: Softomate GHL receptionist entry package (from £2,000 setup + £99/month)

• Phone-answering example: first-year subtotal from £3,188, including £2,000 implementation and 12 monthly payments of £99. VAT, AI, calls, numbers and messages are extra; wider admin workflows are separately scoped.
• 5-year total (assuming 5% annual price increase): approximately £8,600 in setup and monthly fees, plus VAT and usage
• Coverage: the agreed inbound call flow, subject to platform capacity and paid usage
• Missed calls: far fewer for calls handled by the agreed flow
• Savings versus full-time PA: roughly £176,000-£211,000 over five years, before usage and VAT
• Savings versus part-time PA: roughly £76,000-£101,000 over five years, before usage and VAT

Option D: Hybrid (Softomate AI PA + 15 hours/month VA)

• AI element as in Option C: approximately £8,600 over five years in setup and monthly fees
• Virtual assistant: 15 hours a month at £10 to £35 an hour, approximately £9,000-£31,500 over five years
• 5-year total: approximately £17,600-£40,100, plus VAT and usage
• Coverage: AI call handling + human support for complex tasks
• Savings versus full-time PA: roughly £145,000-£200,000 over five years

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 roughly £145,000 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.

How to Calculate ROI Before You Buy

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. If you are unsure, use 35% as a working estimate. Multiply your monthly call volume by 0.35 to get estimated missed calls per month.

Step 3: Calculate the value of missed calls. 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. 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 GHL receptionist entry package has a first-year subtotal from £3,188 (£2,000 setup plus 12 x £99), about £266 a month averaged over the first year, before usage and VAT. 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, comfortably above the cost.

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.

Frequently Asked Questions

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 many UK service businesses, the calculation shows the setup and running cost recovered within a few months, and faster where call volume is the primary driver.
