Business Phone Numbers for Electricians

A landline number for the van, a separate line for commercial clients, and a professional answer while the power is off

One mobile, three kinds of customer

Most electricians juggle very different callers on the same phone: a homeowner whose lights keep tripping, a landlord who needs five EICRs done this month, and a site manager chasing a first fix. They all ring the number on the van, usually while you are in a loft with the power isolated.

SwitchboardFREE lets you give each kind of work its own number, all ringing the mobile you already carry. Call screening tells you which number was dialled as you pick up, so you answer a commercial client like a commercial client.

What an electrical business gets

  • A local number for domestic work: an 01 or 02 number on the van and your Google profile, so homeowners see a local firm
  • A national 03 number for commercial clients: a 03 number costs the same to call as a landline and looks right on a tender or a letterhead
  • Call screening: hear which number or department the caller chose before you are connected
  • Voicemail to email with transcripts: messages arrive as text you can read on a break, not audio you have to find time to play
  • Calls from your business number: call back from the SwitchboardFREE app and customers see the business, not your personal mobile
From £5 per user/month + VAT

Domestic and commercial on separate lines

Commercial clients expect a business number they can put on a supplier form, and they expect it to be answered during working hours. Homeowners are happy to leave a message as long as you ring back the same day. Two numbers on one account let you treat them differently:

  • Different greetings, so commercial callers hear your company name and domestic callers hear a friendly local welcome
  • Different opening hours, with commercial calls ringing the office first and domestic calls going straight to your mobile
  • Different voicemail boxes, emailed to whoever handles that side of the business
  • Separate records: your call logs show which number each caller dialled, so you can see how much work each side brings in

Ready for EICR season

Landlords in England must have their rental electrics inspected at least every five years, and letting agents tend to book those inspections in batches. If landlord work matters to you, give agents their own number or a "press 2 for landlords and agents" option using departments on the Standard and Unlimited plans. Their calls then go to whoever runs the diary instead of interrupting you on a job.

Track which advert brings in the work

If you have branched out into EV chargers, solar panels or battery storage, put a separate number on those leaflets and adverts. Every number rings the same phone, and the call logs show which one was dialled, so you know whether the marketing is paying for itself. Extra numbers are added to your account through the multi-number package.

Growing from one van to a team

When you take on an apprentice or a second electrician, the business number goes with you. Ring both of you at once, ring the office first, or send emergency calls to whoever is on call tonight with time-of-day routing. Engineers call customers back from the app showing the business number, so nobody's personal mobile ends up on a customer's fridge.

Already have a business landline number? You can bring it to SwitchboardFREE for free. Mobile numbers cannot be transferred, so if customers know you by an 07 number, choose a new local number and start using it on the van and your listings. Traditional copper lines are due to finish switching off on 31 January 2027, so if yours is one, it needs to move anyway.

Feature by feature: why SwitchboardFREE works for electricians

Every SwitchboardFREE account comes with over 40 features. These are the ones that make the biggest difference to electricians, and why.

Local and national numbers
Homeowners want a local firm, while commercial clients expect a number they can put on a supplier form or a tender. Put a local 01 or 02 number on the van and a 03 number, charged like a landline, on your commercial paperwork, both ringing the same mobile with their own greetings and opening hours. Extra numbers are added through the paid multi-number package.
Call screening
A landlord chasing EICRs, a homeowner whose lights keep tripping and a site manager after a first fix can all ring within the same hour. Call screening plays a short message saying which number or department was dialled before you are connected, so you answer a commercial client like a commercial client.
Divert calls to your mobile
With the power isolated and your head in a loft, an office landline is no help to you. Calls to your business numbers ring the SwitchboardFREE app on your mobile or divert to any UK phone, so you can take the call when you come down the ladder, wherever the job is.
Voicemail to email
Electricians rarely get the chance to play back voicemails in the middle of a job. Messages are emailed as an audio file with a written transcript, so you can read the address and the fault on a break and ring back with a time.
Call logs
If you have branched into EV chargers, solar panels or battery storage, put a separate number on those leaflets and adverts. Call logs show which number each caller dialled, with the time and duration, so you can see whether that marketing is paying for itself and how much work domestic and commercial each bring in.
DepartmentsStandard & Unlimited plans
Letting agents tend to book EICRs in batches, and those calls are better handled by whoever runs the diary. A menu option such as "press 2 for landlords and agents" sends them to the office with their own voicemail, instead of interrupting you on a job.
Missed call alerts
A homeowner with no power will ring another electrician if nobody picks up. The caller's number is emailed to you the moment you miss them, so you can call back from the van before they move on.
Calls from your business number
When you ring customers back from your personal mobile, that number ends up on their fridge for years. Calls from the SwitchboardFREE app show the business number, so you, your apprentice and a second electrician can all ring customers without handing out your own numbers.
Time-of-day routing
Commercial clients expect an answer in working hours, while evening domestic calls can go to whoever is on call or to voicemail. Different routing by time and day sends each call to the right phone without anyone changing settings every night.
Ring groups
When you take on a second electrician or an apprentice, the business number grows with you. Ring everyone at once, ring the office first and then the vans in order, or share calls out evenly between the team.
Music on holdStandard & Unlimited plans
A commercial client put on hold while you check the diary or a parts order expects to hear a business, not silence. Music on hold keeps them on the line while the office finds an answer.
Call recordingPaid add-on
Commercial work often brings variations agreed on the phone, from an extra circuit to a change in the programme. Call recording lets you play back or download the call, so you can check exactly what was agreed before you invoice.

Questions electricians ask us

Yes. You can have several numbers on one account, for example a local 01 number for homeowners and an 03 number for commercial clients. Each can have its own greeting, opening hours and voicemail, and all of them can ring your mobile.

Call screening plays a short message as you answer telling you which number or department the caller dialled. Your call logs also show the number each call came in on.

Yes. Calls ring the SwitchboardFREE app on your mobile, or can be forwarded to any UK phone. When you call back from the app, customers see your business number rather than your personal one.

The call can ring on to a colleague or the office, or go to voicemail. Voicemails are emailed to you with a written transcript, and missed call alerts give you the caller's number straight away.

No. Plans are rolling monthly with no setup fee, from £5 per user per month plus VAT. You can add numbers and team members as you grow.
