Commercial Cleaning in Cardiff
The capital has more commercial floor space than anywhere else in Wales, and most of it is shared, secured and worked outside office hours. We clean offices, retail, hospitality and managed property across Cardiff on a written specification, with one contact for every site you hold.

Expert Commercial Cleaning for Cardiff Offices and Managed Property
Cardiff concentrates commercial property in a way no other city in Wales does. The centre and Central Square carry the office towers and the professional firms. Cardiff Bay adds public sector, media and waterside offices. The business parks strung along the M4 to the north and east take the units that want parking and a motorway junction. Around all of it sits the retail, hospitality and event trade that fills the city on a match weekend and empties it again by Monday. Cathays and Roath add the managed and let stock behind the centre, and the industrial estates at Tremorfa and East Moors carry the units and workshops on the eastern side of the city.
The consequence for a cleaning contract is not size, it is access. Very few Cardiff buildings are yours alone. Multi-tenant floors, serviced offices, shared cores and shared bin stores mean a cleaning team works to a pass, a permit, a booked lift and a window that closes. Half the buyers are not even the occupier: they are facilities managers and managing agents answering to a landlord, holding several buildings at once and needing every one of them kept to the same standard without being chased.
That is the contract we are set up for. Cardiff is around forty miles east of our base in Penllergaer, so a Cardiff job is planned rather than improvised. Crews are allocated to the city and scheduled into it, which is exactly what a building with a fixed access window needs. We already run regular contracts across Cardiff, so on most days of the week there is a CrewConnect crew working in the city.

What Cardiff Clients Say
A buyer in Cardiff can choose from more cleaning contractors than anywhere else in Wales, so a supplier's record has to do more of the talking here than it does back west.

Llanelli and Carmarthen complete the thirteen areas we cover as standard. If your building sits somewhere not listed here, tell us where.
Common Questions from Cardiff Businesses
Do you cover Cardiff from a Swansea base?+
Yes, and Cardiff is one of the areas we cover as standard rather than an occasional trip. We are around forty miles west of the city, straight along the M4, and crews are allocated to Cardiff work and scheduled into it. That suits how the capital actually operates, because most buildings here need a booked window rather than someone turning up.
What commercial cleaning do you provide in Cardiff?+
Office cleaning contracts, retail and hospitality cleaning, end of tenancy and changeover cleans, post-construction and builders cleans, mould remediation, warehouse and industrial cleaning, and specialist or biohazard work. Everything is for commercial, workplace or managed premises, on either an ongoing contract or a one-off basis.
How quickly can you start a cleaning contract in Cardiff?+
We visit the building first, because access, security and out-of-hours arrangements decide the schedule as much as the floor area does. With the specification, the hours and the access route agreed in writing, the start date is yours to pick. A single void or one-off clean can usually be booked in faster than a multi-site contract.
Do you cover Newport and the areas between Cardiff and Swansea?+
Yes. Newport, Neath, Port Talbot, Baglan and Swansea are all covered as standard, along with Llanelli and Carmarthen further west again. Buildings held across several of them can run on a single contract, to one specification, with one person answerable for the lot, which is usually simpler for an agent than holding a different contractor at each end of the M4.
