How it works with Corestone
Every asset on your estate is tagged and logged. Our engineers scan in on arrival, photograph the work and sign off in the portal, so you can see what was done, by whom and when — without asking.

How we deliver it
The list above is what you buy. This is what actually happens on your site.
We build the asset register first
Before any PPM is scheduled, we walk the estate and record what is actually there — plant, make, model, age, location and condition. Most estates we inherit have a register that stopped being true several years ago.
PPM is planned against the register
Each asset gets a frequency drawn from the statutory requirement, the manufacturer's schedule and its condition. The plan is visible in your portal a year ahead, so you can see what lands in which month.
Reactive jobs are triaged, not queued
The helpdesk grades every call on impact: urgent means a safety issue or a stopped operation. Urgent jobs get an engineer within four hours; everything else gets an appointment you're told about.
Evidence is captured at the job, not afterwards
Engineers scan the asset on arrival, photograph before and after, record parts used and sign off on the device. Certificates attach to the asset record, so a compliance question is a search, not a request.
Lifecycle is reviewed annually
We tell you what is coming to end of life and roughly what it will cost, a year out. Capital surprises are a planning failure, not bad luck.
Where this usually applies
The same service is specified differently depending on the building. These are the sectors where it comes up most.
Offices & business parks
Multi-let estates where tenants judge the landlord by the state of the car park. We run the common parts and the helpdesk tenants actually call.Industrial & logistics
Dock levellers, roller shutters, yard lighting and 24-hour security for sites that never stop moving. Reactive response measured in hours, not days.Education
DBS-checked teams, holiday-period deep cleans and compliance that stands up to an Ofsted or estates audit.Healthcare
Infection-control cleaning standards, HTM-compliant maintenance and security teams trained for clinical settings.
Questions we get asked
Do you subcontract your engineers?
Our core maintenance engineers are directly employed. We use specialist subcontractors for a small number of disciplines that need manufacturer accreditation — lifts and certain fire systems, for example — and those are managed by us, to our standard, with the certificates filed in your portal alongside everything else.
What counts as an urgent call?
Anything that makes the building unsafe, insecure or unable to operate: a total loss of heating, a failed door on the only accessible entrance, an escape route obstruction, a water leak, a security failure. We agree the definition with you in the contract rather than leaving it to interpretation at 3 am.
Can you take over PPM part-way through a contract year?
Yes. We survey the estate, reconcile what has actually been done against what should have been, and pick up the schedule from there. You get a written report of any gaps we find before you commit to anything.
Who holds the statutory compliance responsibility?
Legal duties stay with the duty holder — usually the building owner or occupier. What we do is deliver and evidence the testing regime that lets you discharge them, and tell you clearly when something is outstanding.
