Reviewing a maintenance contract at a desk

Services

Our services at a glance

We audit, control and optimise your existing maintenance contracts. Independent, precise and with your entire building services in view.

Contract documents with a magnifying glass and pen on a desk

What you get

A written audit report per contract: findings, deviations, recommended actions and a priority ranking by urgency.

Maintenance contract audit

In large portfolios, maintenance contracts run for years. Services are invoiced without anyone checking whether they were delivered in full, to standard and at the agreed price. That is exactly where we come in.

Review of all existing maintenance contracts for building services
Technical and commercial review of the agreed services
Comparison of contractually agreed services with the service reports on file

Technician in a hard hat checking a control cabinet

What you get

Inspection notes per system with photo documentation, identified defects and a clear verdict: compliant, compliant with conditions, or not acceptable.

Quality control

A stamped service report says nothing about the quality of the work. We check whether the requirements of the relevant standards and the manufacturer were actually met, on site by sampling and systematically in the documentation.

Verification that work complies with the relevant standards and manufacturer specifications as defined in the contract
On-site spot checks, particularly on safety-critical systems
Review of measurement records for completeness and plausibility

What you get

Structured digital documentation for your entire portfolio, including a deadline calendar.

Documentation

When something goes wrong, what counts is what you can prove. We bring your maintenance records into a structure that withstands scrutiny and keep them permanently up to date with our maintenance system.

Set-up of a uniform documentation structure per property and system
Recording of inspection deadlines, reports, acceptances and defects
Audit-proof filing: traceable, dated, tamper-evident

Calculator and a report with charts on a desk

What you get

A price assessment per contract with concrete savings potential and a recommendation: continue, renegotiate or re-tender.

Cost control

Maintenance fees grow quietly. Line items are carried forward, supplements are added, and eventually nobody pays the price that was once negotiated. We validate quotations and prices and create a solid basis for negotiation.

Review of existing flat fees and individual line items
Validation and optimisation of quotations and prices to minimise cost risks
Comparison with market prices for comparable systems

Why an independent auditor?

Contractors rarely scrutinise their own work critically, and equipment manufacturers recommend their own service contracts. HTA has no stake in either. We are commissioned and paid by the owner, and by no one else.

Start with a single contract

Send us one maintenance contract with its service reports. You get a written finding and know whether more is worth it.
