The best way to compare contractors in Berlin is through reliable selection criteria: entry in the Register of Skilled Crafts, master craftsperson qualifications, guild membership, insurance, the pricing approach offered, reliability on deadlines and references. This is about choosing between companies — rather than comparing prices in individual quotes, which is covered in our guide Comparing contractors' quotes . This guide shows which criteria help you make a sensible choice and where to find reputable companies for each trade.
Key points at a glance
- Compare companies, as well as quotes: qualifications, insurance, pricing approach, reliability on deadlines and references
- For regulated trades, the company must be entered in the Register of Skilled Crafts — with a master craftsperson as owner or technical manager1
- Find companies through the Berlin Chamber of Skilled Crafts' business search (around 29.558 companies) and specialist guilds
- Guild membership is voluntary — an additional quality indicator, not a mandatory criterion3
- Warranty for building work: 5 years under BGB, 4 years under VOB/B — check which form of contract the company uses
What does “comparing contractors” mean?
This is about choosing between several companies — in other words, deciding which contractors to approach and commission in the first place. This differs from simply comparing written quotes (prices, items) and from avoiding typical search mistakes. Both topics are closely related and covered in more depth in separate guides: Comparing contractors' quotes (price and item comparison) and Mistakes when looking for contractors. This article answers the earlier question: which criteria should I use to choose the right companies for my shortlist?
Which criteria should I use to choose between companies?
| Criterion | What to look for |
|---|---|
| Register of Skilled Crafts / master craftsperson | Mandatory for regulated trades — registration can be checked with the Chamber of Skilled Crafts |
| Guild membership | Voluntary quality indicator; some guilds offer dispute resolution services |
| Public liability insurance | Current proof of insurance — covers damage during the work |
| Pricing approach | Fixed price (lump sum) or billing by site measurement — a selection criterion in itself |
| Reliability on deadlines & availability | Realistic commitments on dates, clear communication |
| References | Comparable work, ideally with a contact person |
Where do I find the right company for my trade?
The most reliable source is the Berlin Chamber of Skilled Crafts' business database, filtered by trade and district. Information from the Register of Skilled Crafts shows each company's name, registered tradesperson, trade and address — allowing you to check registration and trade directly.2 Specialist guilds (such as Berlin's plumbing, heating and ventilation guild) also offer their own company searches. Obtain at least three quotes from your shortlist — only around 23 per cent of project owners do this at all, even though prices for the same work often differ by 30 to 50 per cent.
Must a Berlin contractor have master craftsperson qualifications or be registered?
For regulated trades (Annex A of the Crafts Code, which includes most construction and fit-out trades), yes: the owner or a technical manager must hold master craftsperson qualifications, and the company must be entered in the Register of Skilled Crafts.1 This does not apply to unregulated trades. Guild membership, however, is always voluntary — an association of companies in the same trade and therefore an additional quality indicator, not a mandatory criterion.3
Fixed price or billing by site measurement?
The pricing approach a company offers is a selection criterion in itself. With a fixed price (lump-sum contract), the company bears the costing risk and you gain budget certainty. With billing by site measurement (unit-price contract), you pay for the quantities actually completed — fairer when the scope is unclear, but less predictable.4 Also check the warranty: five years for building work under BGB, four years under VOB/B.5 Our guide shows how to identify overpriced quotes through the following: warning signs.
