AI voice assistants

No call goes unanswered. Not on site either.

The assistant picks up when your office can't: evenings, weekends, on holiday, in the middle of a job. It asks briefly what the call is about, answers questions about your services and sends you a summary.

Day-to-day

The phone rings at exactly the wrong moment.

In the middle of a job

You're up on the roof or inside a switchboard cabinet. Your phone rings – and the prospect hangs up after twenty seconds. They call the next person on the list.

The office can't keep up

Between quotes, invoices, and appointments, calls go unanswered. If you don't pick up, the job goes to whoever does.

Evenings, Sundays, on holiday

That's exactly when people call – when no one is available. By Monday morning the contact has gone cold and the enquiry is lost.

From real practice

Here is what that sounds like in practice.

Incoming call

Tuesday, 14:32 · 1:48 min

Hello, do you have any appointments available next week for a PV consultation?
Good afternoon! Yes, I still have a slot free on Tuesday at 2 pm. Shall I book that in for you straight away and let the technician know?
Yes, happy to.
Done. You'll receive a confirmation by text shortly. I've let Mr Siegert know.

Summary sent to your inbox · 14:34

Getting started

Three stages – you decide how far you go.

Stage 1

Free test assistant

You get a test number and hear for yourself how the assistant handles real calls. Then you decide whether it takes over your number.

Stage 2

Available live when no one's there

Evenings, weekends, lunchtimes, and holidays. Exactly the calls that would otherwise mean a callback the next day.

Stage 3

Seamless expansion

Appointments in your calendar, handover to the right person, connected to your system. Once the first stage is running, the rest grows with it.

The process

Three steps – then it runs.

1

The call comes in

Your number rings. If no one's free, the assistant picks up – evenings, weekends and holidays included.

2

The AI takes over and qualifies

It asks what the caller needs, answers questions about your services and recognises whether the matter is urgent.

3

The summary lands with you

Who called, what it's about and what needs doing – as a short message to your phone or inbox.

Expanding

Once the start is working, the rest follows.

The second step is where the real work happens: the assistant becomes part of your workflows. Appointments get scheduled, handovers follow your rules, and the connection to your system is added. I charge for the setup based on the work involved – you decide when you're ready for this step.

Many people start with the entry level and expand two or three months later.

  • Schedule and confirm appointments
  • Integration with calendar, CRM and job management
  • Handover to the right person – on rules you set
  • Multiple locations, languages and opening hours
  • Analysis: what's being asked, what's being booked, what's falling through the cracks
  • Training your team and ongoing support
Concerns

What clients ask first.

Do I need a new phone number?

No. The assistant runs on your existing number. Your customers won't notice any difference – except that someone finally picks up.

Does the agent understand dialects?

Yes, the assistant is optimised for real-world use and handles dialects and accents. If something isn't clear, it asks.

What if the caller has highly specialist questions?

If the assistant can't answer something, it says so openly, notes the question and passes it on to you – rather than fobbing the caller off with wrong information.

Do I need to change the way I work?

No. Getting started fits around your normal working day. We only look at calendars and systems when you want to expand.

15 minutes, no obligation – you hear the assistant live and can ask it your questions.

Who it's for

Businesses with a high volume of incoming calls.

Solar and PV businesses

Enquiries for consultation, connection and expansion – often in waves.

Electrical contractors and master electricians

Small jobs, emergency call-outs and appointments that tie up the office.

Storage, wallboxes, charging infrastructure

Technical queries that can be answered in a standard way.

Heat pumps and heating

Initial consultation during the heating season, when everyone calls at once.

Installers and planning offices

Coordination with clients, authorities and trades.

Service providers with high call volumes

Everything where the phone runs the day instead of the work.

THE CONSULTANT

Insider knowledge from the field, not a theorist.

I know both sides: the workshop floor and the office. I understand how a ten-person business works and how larger companies set up their processes. That's exactly what I draw on when bringing AI into your day-to-day.

What sets me apart from traditional IT consultants: I start with the processes not the tool. And I stay until it works.

The difference: Most AI projects fail not because of the technology, but because of the order things are done in. We work out which process brings in the money first – then we automate exactly that.
Frequently asked questions

Answered briefly.

What does getting started cost?
The entry point is deliberately kept small: sign up and set up a lean assistant. Everything beyond that – appointments, system integration, edge cases – I configure based on the work involved and charge accordingly. You'll get concrete figures after the live demo.
Who is behind the assistant?
I work with an established provider of AI telephone assistants and set it up under your name. The way it presents itself and handles calls belongs to you, not to an outside provider.
Can callers tell it isn't a person?
The assistant says so openly. In practice, that's the point people mind least: they get an immediate answer instead of being put on hold.
What happens when there's a complaint or an emergency?
Calls like these are forwarded immediately according to your rules – to you, to the on-call service, or to a fixed number.
How quickly can you get started?
Usually within a few days: agree on the phone number and question set, test it, go live.
