Bathrooms, showers and sinks
Housekeeping removes scale, soil and accessible biofilm as normal, then adds a short electrostatic pass to the cleaned fittings and surrounding surfaces.
Lease by industry
Office & call centre
Fewer sick days for less than the cost of the absence
Hot-desking, shared headsets and dense floor plates make call centres and open-plan offices efficient transmission environments. Because leasing removes the per-room fee, you can treat floors, meeting rooms and kitchens overnight on a rota — the classic preventative case where the saving is measured in attendance, not in cleaning.
Trusted in the most demanding environments
The same Sanondaf technology is leased and used by our hybrid service teams across NHS England and Scotland, county councils and some of the UK's largest companies and institutions.
Built around your operation
What leasing looks like here
- Overnight, no disruption
- Cycle runs after hours with the floor empty. Staff arrive to a treated space with nothing wet and nothing to move back.
- Hot desks and headsets
- Keyboards, headsets, phones and shared equipment are treated in place — no wiping of hundreds of devices.
- Meeting rooms and breakout
- Small enclosed rooms with poor ventilation are treated between busy days rather than only when someone complains.
- Seasonal programmes
- Step treatment up through flu and norovirus season and back down in summer — the machine is already yours either way.
- Kitchens and washrooms
- The two areas that drive most office-borne illness, treated on the same rota by the same operator.

Time back for your team
One trained team. Fewer hand-offs.
For your organisation, a machine already on site means Open-plan floors and hot desks and other approved areas can be treated on your timetable. In an urgent situation, a trained colleague may be able to start within around ten minutes once the area is prepared — while an external booking may still be awaiting a quote, approval or arrival. Your own signed-off team follows your site standards rather than having to brief a new visitor on them each time.
Stage
External visit
Machine on site
Arrange
Find availability, agree a quote and authorise the job or purchase order.
Your trained operator follows the agreed site procedure.
Access
Wait for arrival, then arrange sign-in, induction, access and an escort.
The machine and trained colleague are already on site.
Treat
Brief the provider, stay available, then check the work against your site standards.
Prepare and clear the area, then follow a familiar, approved treatment cycle.
Close out
Sign out, review the report and process the invoice for the visit.
Record the treatment and follow dwell and safe re-entry rules.
In-house does not mean skipping safeguards: cleaning first, trained operators, your risk assessment, exclusion, dwell time, re-entry checks and a treatment record still apply. A room may be ready within the hour where the validated process and site conditions allow; this is not a guaranteed turnaround.
On site versus called out
The savings chart for this sector
What one area actually costs you
One machine comfortably treats up to 5 rooms per hour depending on their size. But for example, consider two a day — around 60 areas a month — with no per-treatment fee. Divide the monthly lease payment by what you treat, add the chemical used, and that is your true cost.
from £500 monthly lease payment + VAT ÷ 60 = £8.33 each
+ SanoChem used (from £15 / litre + VAT)
from ≈ £10–£12 per treatment + VAT
Indicative figures based on a standard 36-month lease from £450–£550 per month + VAT. Your exact figures depend on machine, volume and site count.
Against calling someone out
- Leased machine, your operator
- 5 minutes to start
- from ≈ £10–£12 + VAT per treatment
- Any external provider
- 6–24 hours to arrive
- from £495–£1,095 + VAT per attended visit
- There is also a cross-contamination consideration: externally transported machines may be wheeled from car parks, vehicles or lower-care areas into your controlled space. A machine kept on site stays within your own hygiene controls.
The saving is only half the point: at this cost you stop rationing treatment and start planning it.

We will confirm exact costs once we know your machine, volumes and site count.
The figures do not assign a cash value to cross-contamination risk. Keeping a dedicated machine on site also avoids externally transported equipment being wheeled in from car parks, vehicles or lower-care areas before it reaches the room being treated.
A quick thought experiment
What would you do tomorrow if a whole pod of twelve calls in sick on the same morning?
The desks, headsets, keyboards and kitchen are all shared. Wiping surfaces feels like doing something, and by Wednesday another two pods are off and the resourcing plan is gone.
With a machine in the facilities cupboard, the floor is fogged overnight and the spread stops at one pod.
See how this plays out in the example belowExample case study
How this tends to play out on site
The scenario below is an example, not a named client. It is built from the situations we are most often asked about in this sector so you can see how a leased machine fits into an existing routine.
Example case study — an illustrative, composite scenario written to show how a lease is typically used. It is not a report of named client work, and no figures here are a guarantee of results.
A call centre keeps a 300-seat floor open through the winter
Illustrative example: a contact centre with hot-desking across two floors
The problem
Absence spikes were being traced to shared desks, headsets and kitchens, and cleaning contracts covered surfaces only when a case was already reported.
How the lease was used
One leased unit is run by the facilities team after the late shift, treating a floor section on rotation and any pod linked to a reported case the same evening.
How it fits the existing routine
In every example the fogging is built into the cleaning schedule already being run. The room is cleaned as normal, the machine is dropped in with a small do-not-enter card showing the safe entry time, and the team moves on to the next room — then leapfrogs the machine into the one just finished. Only a few extra seconds of handling per room, for a full hospital-grade decontamination.
What changed in the example
- Whole-floor treatment overnight, ready for the morning shift
- Desks, headsets, kitchens and toilets treated preventatively on rotation
- Same-evening response to reported cases instead of waiting for a visit
- No residue on keyboards, screens or headsets
Fits your existing process
It blends into the cleaning schedule you already run
Your own janitors, cleaning staff or housekeepers build fogging into their normal daily, weekly, monthly, quarterly or annual rounds. There is no separate programme to manage and no new headcount — the machine simply travels with the round.
- Step 1
Finish the clean as normal
Your team completes the standard cleaning process exactly as they do today — nothing is removed from the existing method or routine.
- Step 2
Drop the machine in, sign on the door
Set the volume, start the cycle and hang a small do-not-enter card showing the safe entry time. The room is then working on its own.
- Step 3
Leapfrog to the next room
Move on and clean the next room. When that one is done, the machine moves into it and the previous room reopens — a simple rolling leapfrog down the corridor.
- Step 4
Seconds per room, not minutes
Done this way it adds only a few seconds of handling per room, and each of those rooms gets a full hospital-grade decontamination rather than a surface wipe.
Why it stacks up
Why office & call centre operators keep a machine on site
Whatever the sector, the reasons organisations keep a machine on site are the same: better press, better attendance, less downtime and a lower environmental cost than the alternatives.
- Blends into your existing rota
- Your own janitors, cleaning staff or housekeepers finish the room as normal, drop the machine in with a do-not-enter card showing the safe entry time, then move on and leapfrog it into each completed room. Only a few extra seconds per room, for a full hospital-grade decontamination.
- Preventative, not reactive
- Once the machine is yours there is no per-treatment fee, so preventative treatment becomes something you schedule during normal downtime rather than something you authorise after an outbreak.
- Peace of mind, future proofed
- Whatever the next virus or outbreak turns out to be, the capability is already on site and the preventative measures are already in the rota. You are not starting from scratch when the headlines change.
- No additional staff cost
- There is no new headcount. Responsible staff you already employ are trained by us, and the routine or emergency treatment simply becomes part of their existing job description and rota.
- 8kg, carried by one person
- The fogger weighs only 8kg and is carried by hand, so there are no wheels rolling contamination out of an infected area, it fits small rooms and large halls alike, and one trained person can deploy it in minutes.
- Certificates you can display
- Every treatment can be logged and issued as a disinfection certificate for reception, customer areas, tender packs or inspections — visible proof that preventative measures are being taken.
- Environmentally sound chemistry
- SanoChem is a hydrogen peroxide and silver formulation that breaks down to water and oxygen. Non-toxic in use, no harsh biocide handling and a genuinely defensible environmental story.
- No residue
- Nothing is left on surfaces, fabrics, food-contact areas or electronics. No rinsing, no wiping down afterwards, no taint or film.
- No waste output
- No run-off to drain, no contaminated water, no piles of wipes and no disposal costs to account for in your waste stream.
- Lower energy cost
- Cycles run in minutes rather than hours, so there is no all-day plant running, no prolonged lighting and heating of a closed area and a smaller carbon footprint per treatment.
- Quick turnaround, higher productivity
- Re-entry is typically inside the hour. Rooms, vehicles and production areas come back into use the same shift instead of being written off for the day.
- Fewer sick days
- Regular preventative treatment of the shared spaces people actually use — canteens, washrooms, offices, mess rooms — is what reduces absence, not treating only the high-risk rooms.
- Broad spectrum, all year round
- Effective against bacteria, viruses, fungi, mould and spores, so the same programme covers winter norovirus and flu, summer mould and humidity, and everything in between.
Planned, not reactive
A planned, visible impression in customer service areas
Dated certificates displayed in reception, meeting rooms, canteens, kitchens and break-out areas show clients visiting and staff on site that hospital-grade disinfection is planned and routine — not a reaction to a problem.
Planned into the calendar
Treatments sit in the rota with dates agreed in advance, so the routine is already in place before an outbreak or an inspection.
A constant positive impression
A dated certificate on the wall answers the question before it is asked, and quietly builds confidence every time someone walks past it.
No increase, however many rooms
The lease payment is fixed and only solution is consumed, so treating more floors, meeting rooms or communal areas does not increase the monthly cost.
Complements the process already in place
Clean as you do now, then close the task with an additional disinfection pass
This does not replace cleaning, descaling, waste removal or physical biofilm removal. Once that work is complete, a selected trained operator can use the electrostatic sprayer for an additional broad-spectrum disinfection step. For a small item or defined work area, it may add only around one minute to the existing process.
Rooms and shared touchpoints
The established room clean stays in place. Electrostatic treatment adds broad-spectrum coverage around cleaned handles, controls, furniture and shared equipment.
A visible close to the turnaround
Log the area, date, operator and machine, then include the treatment in a dated completion record or certificate.
A solid, documentable close to the process
The treatment can be logged against the area, date, operator and machine, then included in a dated certificate or grouped report. Supervisors gain evidence that the conventional clean was followed by a consistent additional disinfection step. Site procedures, manufacturer instructions and current sector requirements always take precedence.
Peace of mind, made visible
Turn preventative treatment into something people can see
Every treatment can be logged and issued as a dated disinfection certificate to display in reception and customer areas. It reassures the people who use your premises, it helps future-proof you against whatever the next virus or outbreak turns out to be, and it shows inspectors and clients that preventative measures are part of the routine rather than a response to a problem.
- Certificates on display
- Issue a dated disinfection certificate after each treatment and display it in reception, waiting areas, canteens or customer-facing spaces. People notice, and it answers the question before it is asked.
- Tell people the good news
- A short notice works well: "For your peace of mind, this area has today received a hospital-grade disinfection. There was no problem here — we simply want it to be extra safe." Preventative measures build far more confidence when they are visible.
- Future proofed against the next outbreak
- Whatever the next virus, variant or seasonal outbreak turns out to be, the capability is already on your premises and already in the rota. You act on day one instead of joining a waiting list.
- No additional staff cost
- No new headcount and no contractor booking. Responsible staff you already employ are trained by us, and routine or emergency treatment becomes part of their existing job description and rota.
Questions we are asked
Office & call centre leasing: frequently asked questions
- How much does it cost to disinfect one area with a leased Sanondaf fogger?
- With a lease from £450–£550 per month + VAT and SanoChem from £15 per litre + VAT, treating around 60 areas a month works out at roughly £10–£12 per treatment + VAT. There is no per-treatment call-out fee, so the more you treat the lower the cost of each one. Use the ROI calculator on this page to enter your own volumes, monthly lease payment and downtime cost.
- How quickly can office & call centre sites respond to an outbreak with their own machine?
- Your trained operator can begin a treatment in about five minutes because the machine is already on site. Calling an external provider means reporting the incident, waiting for travel, site sign-in and equipment movement — realistically six to twenty-four hours. There is also a cross-contamination consideration: externally transported machines may pass through vehicles, car parks or lower-care areas before entering your controlled space, whereas your dedicated machine remains within your own hygiene controls.
- Who can lease a Sanondaf disinfection machine?
- Leasing is offered only to registered organisations that are approved for application, for use on their own sites by staff Sanondaf has trained. We do not lease to private individuals. Typical lease terms are 36 to 48 months and include operator training, two calibration visits and documentation for risk assessments.
- Is the disinfectant safe and environmentally friendly?
- SanoChem is a hydrogen peroxide and silver formulation that breaks down to water and oxygen, leaving no residue and no waste output to dispose of. It is non-corrosive and safe around electronics, and rooms are typically re-enterable in under an hour. It is tested to EN 14476, EN 1276, EN 1650 and related standards, with up to 99.9999% reduction achievable under validated conditions.
- Can we use the machine preventatively rather than only in an emergency?
- Yes — that is the main advantage of leasing. Because each treatment costs around £10–£12 + VAT rather than a call-out fee, office & call centre operators schedule treatments into planned downtime and cover the everyday spaces too, not just the critical ones.
- Can we issue disinfection certificates to display in customer areas?
- Yes. Every treatment can be logged and issued as a dated disinfection certificate, so office & call centre operators display them in reception, customer-facing areas, tender packs and inspection files — visible proof that preventative measures are routine rather than reactive.
- Does leasing mean employing extra staff?
- No. There is no additional staff cost and no new headcount. Responsible staff you already employ are trained by us, and the routine or emergency treatment becomes part of their existing job description and rota.
- How portable is the machine?
- The fogger weighs only 8kg and is carried by hand by one person, so there are no wheels rolling contamination out of an infected area. It fits small rooms and large halls alike and can be deployed within minutes.
- What is required at the start of the lease?
- Three months' lease payments are required upfront, along with a minimum initial SanoChem order of 100 litres unless otherwise authorised. Operator training and documentation are included.
- Is machine leasing available outside Shropshire and the West Midlands?
- Yes. Sanondaf has 12 offices across the UK plus a further six in Scotland, plus offices covering Northern Ireland, Wales, the Channel Islands, Iceland, Lebanon, Thailand, Malta, Mexico, South Africa and the USA — with more areas and countries opening every few months. If you are outside our region we will point you to the office that covers you.
- What if we are unsure how to handle a particular outbreak?
- We can attend with a couple of our own machines at a reduced rate to organise or supervise the response as a hybrid service, then hand it back to your trained operators.

Where we can lease
UK-wide support, coordinated from Shropshire and the West Midlands
Your lease, training and ongoing support is coordinated from the Shropshire & West Midlands office, backed by the wider Sanondaf support network across the UK and further afield. If your group has sites elsewhere, a machine can very often be leased there too, with the same training, calibration and preventative treatment programme — so one policy covers every site rather than one region.
