Sector-Specific Challenges We Understand
Operational continuity
Offices rarely go offline. We plan works outside core hours, in phases, or using temporary solutions to keep your tenants trading throughout.
Multi-tenant complexity
Balancing multiple occupiers — each with different leases and hours — demands precise coordination. We provide it.
Compliance deadlines
EICR renewals, emergency lighting tests, gas safety records — we track every date and deliver audit-ready documentation.
Energy performance
With MEES regulations tightening, improving your EPC rating is urgent. We identify practical, cost-effective routes to improvement.
Landlord-tenant interfaces
Works crossing the demise boundary require careful management. We understand shell-and-core vs fit-out responsibilities.
Agile workspace demands
Hot-desking and tech-heavy fit-outs place new demands on power and environmental control. We design infrastructure that keeps pace.
Our Process
Here's what working with Delta First looks like for an office building or business park, from first survey to ongoing reporting.
-
Initial Consultation & Site Survey
We assess your building, existing systems and current compliance status to understand exactly what's needed.
-
Tailored Service Plan
We agree a scope covering electrical, mechanical, HVAC, fabric and compliance requirements specific to your building.
-
Scheduled & Reactive Works
Planned maintenance is carried out to a fixed schedule, with 24/7 reactive cover for anything unexpected.
-
Compliance Documentation
Every completed job is certified and logged, so your compliance records are always current and audit-ready.
-
Ongoing Reporting & Review
You receive regular reporting on works completed and upcoming renewals, reviewed periodically to keep the plan aligned with your building's needs.
Planned Preventive vs Reactive Maintenance
Most buildings need both. Here's the difference, and when each applies.
| Aspect | Planned Preventive Maintenance (PPM) | Reactive Maintenance |
|---|---|---|
| Purpose | Scheduled servicing to prevent failures and maintain compliance | Response to a fault or breakdown as it occurs |
| Timing | Fixed intervals, agreed in advance | As and when required, 24/7 |
| Typical use | Boilers, HVAC, electrical testing, fire safety checks | Emergency callouts, unexpected failures |
| Documentation | Scheduled certificates and compliance records | Completion report with root cause and follow-up actions |
| Cost profile | Predictable, budgeted annual cost | Variable, dependent on incident frequency |
Our Approach
Delta First operates as a genuine extension of your FM team. We take ownership of your compliance calendar, maintain your asset register, and keep you informed through clear monthly reporting — so you're never caught off guard by a missed certification or system failure. Core works are delivered by our directly employed engineers, fully trained and carrying the relevant accreditations, with vetted specialist subcontractors used only where additional certification or capacity is required.
