Does this sound familiar?

Four service businesses facing the succession question

We know these situations from talks with owners. One of them may be yours.

Your testing service comes back every year

Your inspectors test equipment and installations under DGUV Regulation 3. Clients book again every year. There is no successor in the family.

Your maintenance contracts have run for years

You maintain ventilation, refrigeration, compressed air or doors for commercial clients. The contracts renew every year. The knowledge about each system sits with your master technicians.

Your electrical business lives on service

Besides installations, you look after your clients' systems under maintenance contracts. This part carries your result. A buyer should understand exactly this part.

Your energy service looks after existing systems

You maintain heating systems, combined heat and power plants or photovoltaics for commercial clients. Orders keep coming, technicians are scarce.

Why we buy this sector in particular

Three reasons why we buy in this sector

Operator obligations create recurring orders

Businesses must have electrical installations and work equipment tested regularly. DGUV Regulation 3 and the Industrial Safety Regulation (BetrSichV) set this out. These orders come even in weak years.

Maintenance contracts make revenue predictable

A maintenance contract usually renews every year. The client rarely switches as long as dates and reports are right. That carries the value of your business.

Many service businesses are looking for a successor

Most providers are regional and owner-managed. Often there is no successor in the family or team. We buy these businesses and keep running them independently.

Our acquisition profile

Criteria for this core sector

What we require

  1. EBITDA €0.5m to €5m, profitable and owner-managed.
  2. Based in Germany, succession or majority sale.
  3. Mostly recurring service under contract.
  4. A team of technicians and master technicians that works without the owner.
  5. Digital documentation of tests and maintenance, or a clear path to it.

Value drivers

  • Framework and maintenance contracts with industry and commerce
  • Specialists with their own qualifications and their own client contact
  • Test and maintenance data in a database
  • Clients from several industries and regions

What lowers the value

  • Mostly project and installation business
  • The owner personally holds the key customers
  • If a large share of revenue depends on one customer, the price goes down.
  • Reports completed by hand afterwards

What you get in the first call

The first call takes 30 minutes, is confidential and is held with a partner. We work out your value in the first call using your numbers. Afterwards you get our assessment in writing, even if we decline.

What we plan

After the acquisition: what stays and what is added

We build a group from several owner-managed businesses. Each business stays independent and shares back office and purchasing with the others.

Independent, as before

  • Name, brand and your phone number
  • Location, workshop and vehicles
  • Your team and local management
  • Client contracts and the familiar contacts
  • Your prices and your professional signature

What applies to your company, we put in the purchase agreement.

New in the group

Back-office relief
The system handles invoicing runs, test reports and standard correspondence. Your people check and approve.
Recruiting
Joint job postings, training paths and cover between the businesses in the group.
Joint client development
Your clients often need services from the sister businesses too. We only recommend them with your consent.
Purchasing
Measuring equipment, vehicles, spare parts and insurance on terms for the whole group.
Capital
Equity from the fund is available for filling positions, expanding locations or add-on acquisitions.
Why this route

Succession is settled, and your business stays independent under its own name. In the group it buys more cheaply and finds staff more easily. You decide whether you keep leading or leave after the handover.

Why we buy this sector
A service business lives on clients who have come back for years. We buy these businesses with their technicians and master technicians and run them on under their own name.

Frequently asked questions

What owners ask us

Do you also buy electrical or metalworking businesses with project work?

Yes, if a service unit with maintenance contracts delivers a substantial part of the result. We do not buy pure installation and project businesses.

How large does my company have to be?

Our acquisition profile starts at €0.5m EBITDA. For electrical testing, we look for at least 10 field inspectors. We buy smaller businesses as add-ons to an existing platform.

What happens to my technicians?

All employment contracts remain in place. The system creates the documentation, your technicians check and approve it. Your people stay in the field with the clients.

How long do I have to stay after the sale?

You decide. 6 to 24 months as interim managing director is common, often followed by an advisory board seat.

How quickly do I get an answer?

Usually within 72 hours after the first call. An indicative offer follows 2 to 4 weeks after we have seen your documents. We usually expect 6 to 9 months to closing.

What is my company worth?

The value is determined by the adjusted EBITDA of recent years. Recurring contracts and an independent team raise it. We work out your value in the first call using your numbers.

Should I sell with an M&A advisor?

That is your decision. Many owners work with an advisor, and we are happy to work with them. A good advisor prepares documents and saves both sides time. If you come directly, the partners run the process themselves. In any case, you should bring in your own lawyer and tax advisor.
