TTB

What TTB does

TTB (Totaal Techniek Brekelmans) is a privately held Dutch installation services company headquartered in Apeldoorn, operating since 1895 (under current ownership since 2011 by Leon Brekelmans and rebranded to TTB in 2016). The company delivers total installations across three integrated disciplines: Elektrotechniek (electrical engineering, DALI-controlled lighting, fire detection, access control, security systems), Installatiewerk (mechanical installations including HVAC, cooling, sanitary, zinc/lead metalwork), and Duurzame Technieken (sustainable energy solutions encompassing solar PV, heat pumps, biomass/pellet boilers, battery storage, and ground heat recovery). A distinct specialty is monumental/heritage building installations, supported by Kennis & Kunde registration and training through Gelders Restauratie Centrum, allowing the company to retrofit sustainable technologies into protected structures such as castles, churches, and historic houses.

The business serves commercial, industrial, healthcare, government, and heritage property clients primarily in the Gelderland and Overijssel regions of the Netherlands, with project evidence extending to nationwide work. Notable clients include Geldersch Landschap & Kasteelen (covering 700+ monumental properties since the late 1990s), Gemeente Apeldoorn, Hörmann Nederland, Holland Norway Lines (cruise ferry terminal at Eemshaven), Riwis care apartments, and La Coquerie. TTB integrates third-party technologies — SolarEdge for PV, Froling for pellet boilers, NSC for fire detection, ARAS Security's NOX systems for integrated building management, and Uniview for camera surveillance — within its own design, project management, and maintenance offering.

The revenue model combines one-time project work (design, engineering, installation, execution) with recurring service and maintenance contracts delivered through a Syntess-based customer portal. Pricing is quote-based and not publicly disclosed, structured as multi-year contracts. GTM is direct field sales with a single fixed contact point per customer, supported by a content marketing and project-portfolio-driven website. The company is not funded externally — there are no disclosed funding rounds, parent company, or M&A activity — and operates with roughly 14-16 employees, placing it firmly in the small regional SMB category of the Dutch installation sector.

Its core offering combines sustainable energy systems (PV installations, heat pumps, biomass/pellet boilers, battery storage), electrical engineering (lighting, power, access control, fire detection), and mechanical installations (heating, cooling, ventilation, sanitary, zinc/lead work) under a single point of contact from design through execution to ongoing maintenance. The company holds specialized heritage-building expertise with registered qualification in the Kennis & Kunde restoration database.

Product overview

TTB (Totaal Techniek Brekelmans) is a full-service installation company offering integrated technical solutions for residential, commercial, and monumental buildings. The portfolio is organized around three core disciplines: Elektrotechniek (electrical engineering including lighting, power, security, and fire detection), Installatiewerk (mechanical installation including heating, cooling, ventilation, and sanitary systems), and Duurzame Technieken (sustainable technologies including solar panels, heat pumps, biomass, and battery storage). TTB positions itself as a total installation partner (totaalinstallateur) providing complete solutions from design and engineering through execution to ongoing service and maintenance. Key products include PV-installaties (solar panels), warmtepompen (heat pumps in various capacities), pelletketels (pellet boilers with up to 102% efficiency), accuopslag (battery storage), and airco systemen (split/multi-split AC). Electrical offerings encompass verlichting en krachtinstallaties with DALI control, brandmeldinstallaties (fire detection via NSC partnership), toegangscontrole en beveiliging using NOX Systems, and Energiemanagementsysteem for smart energy optimization. Service offerings include Service & Beheer (maintenance contracts with KIWA and InstallQ certification), Monumentale Werken (heritage building specialists registered in Kennis & Kunde), and Totaalinstallaties providing single-point-of-contact project coordination. A Syntess-based Klantportaal enables customers to manage work orders and submit maintenance requests digitally.
