The warning signs in a commercial fit-out are usually a quote without detail, a contractor who promises to sort out licences or says none are needed, no questions about your activity or the building, fixed dates before the scope is clear, and no mention of insurance or guarantee. Each points to risks that show up later in cost, time or compliance. Ask for an itemised quote and clear answers before signing.
The quote is a single line or a round figure
A quote that says “shop refit, complete” with one total tells you nothing about what is included. When something turns out to be missing — the ceiling, the toilets, the levelling, the cleaning — it becomes an extra. An itemised quote lists each task with a description and a quantity, and says what is excluded. It takes longer to prepare, which is part of the point: it shows the contractor has looked properly at the unit.
Someone promises the licence will not be a problem
Be wary of any contractor who says that “no licence is needed” or that “we will sort out the paperwork” without a technician involved. Whether a declaración responsable, a licence or a technical project is required depends on the activity, the works and the town hall, and it is the business owner’s responsibility, normally handled through an architect, engineer or consultant. A builder who brushes this aside is either guessing or taking a risk with your opening.
We do not process licences, and we say so. We build to the scope your technician defines. Our licences guide explains the framework.
Nobody asks about your activity or the building
A café, a clothes shop and a dental clinic need very different things from the same unit. If a contractor quotes without asking what the business does, how many people will work there, whether there is food, noise or special equipment, or what the community and the landlord allow, the quote is probably based on assumptions. Those assumptions will be corrected later, at your cost.
A firm opening date before the scope is settled
Everyone wants a date. But a date given before the layout, finishes, specialists and paperwork are settled is a hope rather than a plan. A more trustworthy answer explains what the schedule depends on and gives a phased plan once those things are clear. The guide on planning a refit around trading covers what drives the timeline.
No mention of insurance, guarantee or who does the electrics
Ask whether the contractor has public liability insurance and what guarantee applies to the work. Ask who carries out the electrics and plumbing, and whether they are authorised installers; in our case they are authorised partner installers, coordinated within our schedule. If the answers are vague, the protection behind the work probably is too.
What does a reassuring answer look like?
It helps to know what good looks like, not only what to avoid. A careful contractor usually asks for photos and floor area, then wants to see the unit before giving a final figure. They ask what the business does, who your technician is and what the lease and the community allow. Their quote lists each task with a quantity and says what is excluded, including specialist systems. They explain what the schedule depends on instead of promising a date in the first conversation.
They also say clearly what they do not do. A contractor who tells you that licences and technical projects belong to your architect or engineer, and that air conditioning or extraction will come from specialists, is not being unhelpful; they are drawing the lines that prevent gaps later. Confidence in a contractor should come from precision, not from how many problems they promise to make disappear.
Finally, notice how changes are handled. A good contractor explains that unexpected findings will be shown to you with photos, priced as separate lines and only carried out once you approve them. That single habit prevents most disputes about extras at the end of a job, and it keeps you in control of the budget throughout.
Other signs worth noticing
- A large payment requested up front without a clear link to materials or stages.
- Reluctance to put changes in writing.
- No site visit before a final price.
- Specialist systems — air conditioning, extraction — quietly left out of the conversation.
- Pressure to decide quickly “because a slot is available”.
