Having general terms and conditions for electrical engineering drafted by a specialized SME lawyer typically costs between €350 and €900, depending on the complexity of your installation work. You will receive terms and conditions tailored to assembly and installation, warranty on workmanship and materials, liability, completion, payment, and NEN standards — and which will hold up if a customer files a claim or fails to pay. Below, you can read what the process entails, what it costs, and when it is worth the investment.
The short answer
- Costs: €350 – €900 for a custom-drafted template from an SME lawyer.
- Lead time: usually 1 to 2 weeks.
- Process: intake, concept, review, final version.
- Result: conditions that align with your working methods and insurance.
- When: for larger projects, consequential damage risk, or a mix of clients.
Having general terms and conditions for electrical engineering drawn up: how does it work?
A legal expert does not draft your terms and conditions blindly, but begins with an intake regarding your installation company: what work you do (installation, renovation, maintenance), for which clients (residential, commercial, or both), what warranty periods you apply, and how you are insured. Based on this, a draft is created that is tailored to assembly and installation, warranties on workmanship and materials, liability, completion, and payment.
It is important that the liability limitation aligns with your insurance coverage and that the guarantee scheme fits what you can actually deliver in practice. A standard model that is not tailored to anything lacks that alignment.
The steps in the process
- Intake. Discussion about your work, clients, risks, and insurance.
- Draft. The legal expert prepares a first version, tailored to electrical installations.
- Review. You read along and indicate where it does not align with your practice.
- Final version. Processing your comments into a conclusive set.
- Implementation. Include a reference in your quotations and send it as an attachment to ensure the delivery is correct.
How much does it cost?
The price depends on the complexity of your work and whether you want custom work or a modified model:
- Ready-made template: €75 – €200 for an industry model that you fill in and adapt yourself.
- Tailor-made: €350 – €900 with a specialized SME lawyer, including intake and one review round.
- Extensive customization: €900 – €1,500 for complex projects with installment payments, inspections, consequential damage risk, or a separate consumer version.
- Standalone check: €150 – €400 to have existing terms and conditions checked and updated.
For most installation companies, the best value for money lies in the tailor-made category: it doesn't differ much from an industry model, but you get terms that truly align with your work and insurance.
Do it yourself, buy a model, or have one drawn up?
Three routes, each with its own considerations:
- Drafting it yourself. It is the cheapest option, but the risk is that the liability clause or warranty provision will be invalidated. Only advisable for simple standard work and if you are familiar with the subject matter.
- Buy a model. Fast and affordable. Works well if you tailor the model to your own situation — terms, insurance, NEN references.
- Have them drafted. More expensive, but you get terms and conditions tailored to your risks and legally reviewed. It pays off as soon as the stakes rise.
When is having it drawn up worth the investment?
Having it drawn up pays off, especially in these situations:
- Larger projects. Installment payments, additional work, and phased delivery require precise terms.
- High risk of consequential damage. If you work on installations where failure leads to business interruption, comprehensive limitation of liability is crucial.
- A mix of clients. Both private and business customers require a consumer version that respects the black and grey lists.
- Insurance alignment. If the limit in your terms and conditions does not align with your policy, a gap arises that you bear yourself.
Practical example
An installation company used a free template from the internet for years. After a damage claim, it turned out that the limitation of liability did not align with the policy and consequential damage was not excluded. The company subsequently had the terms and conditions custom-drafted for approximately €600, tailored to its own insurance and including a clear NEN reference and warranty provision. In the subsequent dispute, the limitation of liability did hold up — a fraction of the damage that would otherwise have remained unresolved.
Honest recommendation
You do not need to hire a lawyer in all cases. If you handle straightforward standard work with limited risks and have a good grasp of the subject matter, you will get away with a good industry model plus your own adjustments—provided you submit it on time. However, as soon as you work with larger projects, installment payments, consequential damage risks, or a mix of private and business clients, the investment of €350 to €900 is well worth the risk of a crucial clause failing at the decisive moment. In doubt? Then at least have your existing terms and conditions reviewed; that is the cheapest way to know if they will hold up.

Frequently Asked Questions
With a specialized SME lawyer, the cost is typically €350 to €900 for a custom-drafted template, including the intake and one review round. A ready-made industry model costs €75 to €200; extensive customization with installment payments and a consumer version rises to €900 – €1,500.
Usually 1 to 2 weeks. After the intake, the legal expert prepares a draft, which you review to ensure it aligns with your practice, after which a final version follows. The turnaround time depends primarily on how quickly you provide the intake information and review the draft.
For simple standard work, an industry model may suffice, provided you adapt it to your own terms, insurance, and NEN references. The risk is that an unaligned model leaves a gap between your terms and your policy, or contains a clause that fails in your case.
A description of your activities (construction, renovation, maintenance), your client groups (private or business), the warranty periods you apply, and your insurance details. The clearer this picture, the better the legal expert can tailor the limitation of liability and warranty arrangements to your situation.
For larger projects with installment payments, a high risk of consequential damage such as business interruption, or a mix of private and business clients. In those cases, the investment is far outweighed by the risk that a liability or warranty clause fails at the decisive moment.
Yes. A standalone check typically costs €150 to €400. The legal expert checks whether the limitation of liability aligns with your insurance, whether the warranty scheme is correct, and whether the NEN references and payment clauses are up to date. That is the cheapest way to know if your terms and conditions hold up.
Registration is not mandatory and is not decisive for their validity. What does matter is that you provide them on time: refer to them in your quotations and send them along as an attachment before or at the conclusion of the agreement (Art. 6:233 BW). Without timely provision, the customer may annul the stipulations.
