Mobile Phone systems for Cleaning Businesses
NEW BOOKINGS RING WHILE YOU'RE
MID-CLEAN
Gloves on, hoover running - and the phone goes. It might be a one-off enquiry, or it might be the weekly office contract that keeps your diary full for a year.
ONSIM gives cleaning businesses a professional landline number on the mobile you already carry, all natively ON-A-SIM. Business calls stay separate from personal ones, and your team can share one number as you grow.
Look established to landlords and facilities managers, and never let a booking slip away.
A spotless way to handle calls
Tailored Phone Solutions for Cleaning Businesses
Key Features Built for Your Business:
A full office phone system without the office - on the mobile in your pocket, wherever today's jobs take you. No apps, no Wi-Fi, no desk phone gathering dust.
Business and Personal, Separated
One phone, two numbers. You instantly know a call is business before you answer - so you can pick up professionally during work hours and actually switch off in the evening.
Never Lose a Booking Mid-Job
Can't answer with your hands full? Divert to whoever handles your diary, let another cleaner on the team pick up, or send it to voicemail and ring back between jobs - the enquiry doesn't vanish.
Win Commercial Contracts
Offices, landlords and letting agents award contracts to companies that look established. A landline number on your website, invoices and proposals reads as a proper cleaning firm - not a side gig.
Grow Without Changing Number
Start solo, then add SIMs as you take on staff. Hunt groups ring the whole team from one business number, and everyone dials out showing it - the number on your flyers never has to change.

Still have doubts?
How do I stop mixing business calls with personal ones?
Give the cleaning business its own landline number that rings on the phone you already own. With a Landline SIM you see instantly that an incoming call is business, and when you ring a client back they see the business number - your personal mobile stays private. If you just want inbound calls forwarded, a Virtual Landline does that from £5/month + VAT.
I'm usually mid-clean when the phone rings. What are my options?
Whatever suits how you work: let voicemail take it and call back between jobs, divert calls to a partner or whoever manages your bookings, or - on multi-user Landline SIM accounts - use a hunt group so the business number rings more than one phone and someone free answers.
Will a landline number help me win commercial cleaning contracts?
Facilities managers, landlords and letting agents dealing with contract cleaners expect a business they can get hold of reliably. A landline number on your proposals and website presents an established company, and because it rings your mobile, you're just as reachable on site as at a desk. Pick an area code that matches where you work from our local numbers range.
We're a small team - can we all answer the same number?
Yes. Each team member gets a Landline SIM in their own phone, and a hunt group rings you simultaneously or in sequence from the one business number. One hunt group is included on accounts with 2+ users, and everyone can display the company number on outbound calls.
Do my cleaners need to install anything?
No. This is not a VoIP app - the SIM goes in the phone (or arrives instantly as an eSIM) and calls work like any normal mobile call, using the phone's own dialler. Nothing to install, no logins to forget, no Wi-Fi needed inside clients' properties.
Can I keep the number that's already on my flyers and Google listing?
Yes - port your existing landline or mobile number to ONSIM and keep every flyer, review and listing valid. Porting typically takes 10–14 working days and the port-in fee is covered.
What does it cost?
Virtual Landline from £5/month + VAT - a business number with inbound calls forwarded to your existing mobile. Or Landline SIM from £10/user/month + VAT - unlimited UK calls and SMS, with the business number shown on calls you make too. Both monthly rolling, cancel any time - handy while you're still growing.
