The verdict in three sentences
For a MEP and energy engineering consultancy in Berlin, a single mission won through the website, worth 4,000 to 25,000 EUR in fees, covers the cost of the project. The site must prove technical competence through quantified case studies and capture regulatory searches (GEG, EU EPBD, mandatory energy audits), where property owners looking for a consultant actually search. Plan 4 to 6 weeks and a budget of 1,830 to 3,050 EUR at Kolonell, versus 5,000 to 12,000 EUR with a Berlin agency.
What clients look for on your website
A developer, a commercial property manager or an architect compares three or four consultancies before requesting a proposal. They want to check your references, your accreditations and your ability to meet regulatory deadlines.
| Site element | Expected content | Commercial effect | Priority |
|---|---|---|---|
| Reference pages | 10 to 20 projects: floor area, use, scope, year | Reassures on experience by building type | Must-have |
| Quantified case studies | Consumption before/after in kWh/m²/year, gain in %, works cost | Demonstrates value, supports your fees | Must-have |
| Commercial building compliance page | EPBD renovation targets, energy certificates, reporting duties | Captures portfolio managers | Must-have |
| Pre-assessment form | Floor area, use, construction year, energy bills | Qualifies the lead before the first call | Must-have |
| New-build compliance page | GEG requirements, energy calculations, permit support | Captures developers and architects | Recommended |
| Team and accreditations | Engineers, certifications, software used | Credibility in tenders | Recommended |
| Regulatory blog | 1 to 2 articles per month on 2026 to 2028 changes | Lasting qualified organic traffic | Recommended |
The pre-assessment form is the most profitable module: it turns an anonymous visitor into a usable file, with the data needed to price a proposal in a day.

Mini case study
Need a professional website?
Kolonell builds websites that attract clients, optimized for the Sénégalese market. Free quote in 2 minutes.
Thomas, managing director of a 9-engineer MEP consultancy in Berlin, bills an average of 9,000 EUR per mission. He invests 2,500 EUR in a Growth tier website and 300 EUR per month of SEO for 12 months, so 6,100 EUR in year one. Conservative assumption: the site generates 2 additional missions over the year, 18,000 EUR in fees. With a 35% margin, that is 6,300 EUR of margin, which covers the investment in year one; the third mission becomes net profit.
FAQ
How much does an engineering consultancy website cost in Berlin in 2026?
A Berlin agency typically charges 5,000 to 12,000 EUR excluding VAT. At Kolonell, the Growth tier ranges from 1,830 to 3,050 EUR, with blog and analytics included.
How long does it take to go live?
Count 4 to 6 weeks if your references and case studies are ready. Collecting project figures is often the longest step.
Should we publish client project consumption data?
Yes, with the owner's consent or in anonymised form: a stated 35% gain in kWh/m²/year is far more convincing than a general description.
Does regulatory SEO really work?
Queries tied to energy compliance are not very competitive locally. Count 3 to 6 months for first rankings with a plan starting at 100,000 FCFA, about 150 EUR per month.
Can we add an energy savings calculator?
Yes, as a custom tool. A simple application starts at 3,810 EUR according to our grid; a pre-assessment form is often enough at launch.
