Facilities management in Sheffield
Our head office and our 24-hour helpdesk are both in Sheffield. It is the city we know best and the one we can reach fastest.

Our Sheffield office
Corestone started in Sheffield with two engineers and three buildings, and the head office has never moved. The helpdesk that answers your call at 3 am is staffed from here, 365 days a year — not from an offshore call centre and not from an answering service.
Because our engineers, cleaners and security officers are directly employed and based locally, a four-hour urgent response across South Yorkshire is something we control rather than something we subcontract and hope for.
A city of converted industrial stock
A lot of Sheffield's commercial space is former industrial buildings adapted for offices, studios and light manufacturing. They tend to come with oversized heating systems, awkward roof details and services that were never designed for the use the building has now. That shapes how we write a PPM schedule here.

Sheffield questions
Our other offices: Leeds and Manchester.
How quickly can you get to a site in Sheffield?
Urgent calls carry a four-hour attendance target across South Yorkshire, and in practice a city-centre or Lower Don Valley site is usually a lot quicker than that because the engineers are based here. We agree the definition of urgent with you in the contract rather than leaving it to interpretation at 3 am.
Is the helpdesk really in Sheffield?
Yes. It is staffed from our head office, 24 hours a day, 365 days a year, by people who know the sites they are taking calls about. It is not an overflow service and it is not offshore.
Do you cover Rotherham, Doncaster and Barnsley?
Yes — all three are served from Sheffield, along with Chesterfield and Worksop. If you are further out than that, tell us where and we will say honestly whether we can hold our response times to it.

A contracts manager will come out, walk the sites and give you a written report. No charge, no commitment.
