Advisory for clients in the public and private sector

The procurement of cleaning services is one of the most complex tasks in facility management. Hygiene standards, cleaning methods, quality requirements, and economic targets must be precisely defined — alongside full compliance with procurement law — whether for administrative buildings, schools, hospitals, or industrial sites.

Frequently asked questions

Building Cleaning

What does it cost to support a building cleaning tender?

Costs depend on the scope: number of properties, lot structure, floor area and the extent of support required. Fixed-fee or hourly-rate models are both common. You will receive a clear estimate in the no-obligation initial consultation.

How long does a building cleaning tender take?

With thorough preparation, below-threshold procedures can be completed in 3–4 months. Open procedures above EU thresholds realistically take 6–9 months. Preparation is the decisive phase — it determines whether the procedure runs smoothly.

What are the most common mistakes in cleaning tenders?

Inaccurate floor area surveys, missing hygiene zone definitions, unverifiable quality criteria and overly generic evaluation matrices. These weaknesses generate tenderer queries, uneconomic bids and disputes during contract performance.

Can we run the tender process in-house?

Yes — if sufficient internal capacity and up-to-date sector knowledge are available. External support is particularly valuable for first-time tenders, after long contract periods, or when the previous procedure led to operational problems.

Fixed-Price Works, Hour Requirements, and the Legal Limits of Invoice Deductions

Under settled German case law, cleaning contracts are classified as works contracts (Werkvertrag) — what is owed is a clean result, not a set number of working hours. Yet in practice, clients regularly reduce invoices on the grounds that contracted or estimated hours were not delivered. Whether such deductions hold up legally depends less on how the contract is labelled and more on three specific questions: Were the hours expressly agreed as a binding performance obligation? Is the reduction clause sufficiently transparent? And does it survive scrutiny under Germany's standard terms control regime? This article maps the relevant case law — from the 2019 Federal Court of Justice judgment to the diverging Court of Appeal rulings from Hamm, Düsseldorf, and Cologne.
