What JK+ does
JK+ is a Danish multi-disciplinary technical installation company with more than 45 years of operating history, headquartered in Glamsbjerg on the island of Funen and operating four regional branches in Middelfart, Faaborg, and Nyborg. The business is structured as two wholly-owned Danish public limited companies — JK+ Elinstallation A/S and JK+ Alarmteknik A/S — and runs five integrated service divisions: electrical installation, certified alarm and security systems (ABA fire alarms, ABV fire ventilation, AVA evacuation, AIA intrusion, ADK access control, and TVO video surveillance), ventilation with heat recovery, IT/fiber/telephony, and renewable energy (solar panel systems and heat pumps). The technology stack is anchored by ISO 9001 certified alarm installations, DBI AVA certified work, VE-approved (Energistyrelsen) solar and heat pump installations, Rigspolitiet- and F&P-authorized security systems, and CTS-anlæg (building management systems) that integrate heating, ventilation, lighting, and security into a single automation layer for energy optimization.
JK+ serves residential, commercial, industrial, educational, and public-sector customers across Funen and the Trekantområdet via direct field sales from its four branches, supported by named project and account managers. Revenue is generated through a hybrid model combining one-time project work (new installations, renovations, EV chargers, solar and heat pump installations) with recurring service contracts (annual ventilation, heat pump, and managed IT maintenance), supplemented by government-subsidized residential work (e.g., 2023 subsidies of 17,000-27,000 DKK for heat pumps) and exclusive-partnership placement of Midea heat pumps in Denmark via the Lemvigh-Müller wholesale channel. Pricing is project-based and quote-driven for most engagements, with subscription billing for managed IT and selected service agreements.
Distribution is exclusively direct, with no reseller or channel partner model. Notable project clients include Tietgen Skolens Erhvervsuddannelse (DGNB Gold certified), Fredericia Kommune, United Components A/S, Sports Academy Denmark, Assens Fjernvarme, Borgvold Hotel, Nyborg Gymnasium, and Danske Veteranhjem, with the company citing more than 800 completed project references. JK+ is privately held, owner-managed (CEO Anders Kristensen and Alarm-Director Daniel Küster), and operates with no disclosed external funding or institutional shareholder.

JK+ competitors and assessment
Company assessmentDirect peers
- Kemp & Lauritzen: Kemp & Lauritzen is one of Denmark's largest electrical and technical installation companies, offering electrical, security/alarm, ventilation, and energy solutions — directly comparable to JK+'s five-division model with national coverage versus JK+'s regional Funen/Trekantsområdet focus.
- Bravida Danmark: Bravida Danmark is the Danish arm of Nordic technical installation firm Bravida, providing electrical, HVAC, fire/security, and telecom services to commercial and public-sector customers — a direct competitor for the same multi-trade installation and service-contract opportunity JK+ targets.
- Caverion Danmark: Caverion delivers building technology, electrical, HVAC, and security installations across Denmark, closely overlapping JK+'s integrated multi-trade service offering and energy-optimization (CTS/BMS) focus for commercial and public-sector clients.
- Lindpro (Søndergaard Holding): Lindpro is a Danish electrical installation and automation contractor with offices across regions of Denmark, comparable to JK+ as a regional technical installer competing for the same industrial, commercial, and public-sector project pipeline.
- El:Con (El-Installatørernes Landsforening cooperative members / Elcon group): El:Con is a Danish electrical and technical installation group with multiple regional entities offering electrical, automation, and security services; competes head-to-head with JK+ for project and service business in Jutland/Fyn.
- SikkerhedsBranchen member installers (e.g., Dansikring): Dansikring and similar SikkerhedsBranchen-member installers offer certified alarm, access control, and video surveillance installations in Denmark, directly comparable to JK+ Alarmteknik's ISO 9001 certified alarm portfolio (ABA, AIA, ADK, ABV, AVA, TVO).
- Wicotec Kirkebjerg: Wicotec Kirkebjerg is a Danish technical installation company offering electrical, plumbing, HVAC, and security solutions with strong public-sector and industrial project exposure — directly comparable in service breadth and customer profile to JK+.
Broad incumbents
- Solar A/S (Solar Danmark): Solar Danmark is a major Danish technical wholesaler and installation-services provider with a broad nationwide portfolio overlapping solar, heat pump, and electrical categories where JK+ competes, but at significantly larger scale and broader geographic reach.
- ISS A/S: ISS is a large Danish-headquartered global facility services company whose technical services and building-maintenance offerings span many of the same electrical, HVAC, and security maintenance contracts that JK+ services — a much larger incumbent with broader scope.
Regional players
- Eltel Group: Eltel is a Nordic electrical-infrastructure and installation services company active in Denmark and the Nordics, comparable in core electrical-installation capability but primarily focused on power and telecom infrastructure versus JK+'s building-services focus.
