Intrusion protection is an investment in security, quality of life and the value of your property. What many do not know: the German state supports you in this. Through the KfW banking group you can finance alarm systems, smart door locks, camera systems and further security technology at favourable interest rates – with loan amounts of up to 50,000 euros per residential unit. "Security is not an expense – it is an investment that pays off twice."
KfW funding for intrusion protection – what is it?
The KfW banking group (Kreditanstalt für Wiederaufbau) is Germany's largest national development bank. It supports private individuals, businesses and municipalities with low-interest loans and grants – including for measures aimed at intrusion protection and barrier reduction.
For several years, KfW has explicitly funded security technology as part of its programme "Age-Appropriate Conversion". The background: barrier-free living and intrusion protection go hand in hand – because secure dwellings enable older people in particular to live independently in their own home for longer.
The KfW Programme 159 in detail
The programme relevant for intrusion protection is KfW 159 "Age-Appropriate Conversion – Loan". Despite its name, the programme is not tied to any age – every owner and tenant (with the landlord's consent) can use it, regardless of age.
What the programme offers:
- Low-interest loan of up to 50,000 euros per residential unit
- No age limit – for owners and tenants
- Can be combined – intrusion protection can be combined with barrier reduction
- Repayment-free start-up period – depending on the variant, up to 2 years
- No proof of own capital required
The KfW loan must be applied for before the measure begins. Do not sign an installation order before the application has been submitted. Protexium will gladly support you with the timing.
Which security technology is eligible?
Under Programme 159, KfW funds a wide range of security measures. Particularly relevant for Protexium customers:
Intrusion detection systems
Alarm systems with door and window contacts, motion detectors, glass-break sensors and sirens. The system must be professionally installed – self-installation is generally not eligible for funding.
Video surveillance systems
Outdoor and indoor cameras with recording, night vision and remote access. Door cameras and video intercom systems are also covered by the funding.
Smart door locks
Electronic locking systems with app control, fingerprint sensor or keypad code. These replace conventional locks and also provide access logging.
Lighting systems with motion detection
Automatic outdoor lighting that is activated by movement and can be integrated into the overall system as a Smart Home component.
Intercom systems
Modern video intercom systems with remote access that allow visitors to be identified and spoken to even from elsewhere.
Application step by step – how it works
The route to KfW funding is simpler than you might think:
- Step 1 – Security analysis: Start with a free security analysis to determine the exact requirements. This will tell you which components are eligible.
- Step 2 – Obtain quote: Protexium prepares a detailed quote that shows the eligible components separately – ideal for the KfW application.
- Step 3 – Apply for the KfW loan: You submit the application through your own bank. Protexium's quote serves as proof of costs.
- Step 4 – Await approval: Once the loan is approved, you can issue the installation order.
- Step 5 – Installation & proof: After professional installation, you submit the invoice to KfW.
Bonus: lower insurance premiums
A professional security system saves money not only through KfW funding – it also reduces your insurance premiums. Many building and home contents insurance policies grant discounts of 5 to 15 per cent when a certified alarm system is installed. With an annual premium of 800 euros, that means savings of up to 120 euros per year – permanently.
Requirement: the system must be installed to recognised standards. Protexium systems meet EN 50131 and are supplied with full documentation that your insurer accepts as proof.
Worked example: what you actually save
Let us look at a specific example – a typical detached house with alarm, cameras and a smart door lock:
With a KfW loan of 6,500 euros at 2.86% effective annual interest and a 5-year term, you pay around €115 per month – less than many streaming subscriptions combined. Add to this the annual insurance savings and the priceless value of being able to sleep soundly at night.
Frequently asked questions on KfW funding
Is KfW funding for intrusion protection still available in 2026?
Yes. Under the KfW Programme 159 "Age-Appropriate Conversion" alarm systems, smart door locks, camera systems and intercom systems can be financed with a low-interest loan of up to 50,000 euros per residential unit. The programme applies only to properties located in Germany.
Does the alarm system have to be installed before applying for KfW funding?
No – on the contrary: the KfW loan must be applied for before the measure begins. Start the application first and then commission the installation.
Is retrofitting existing buildings also eligible?
Yes. The KfW Programme 159 is expressly aimed at existing properties. New builds are eligible for funding through other programmes.
Can I combine KfW funding with other grants?
In principle yes, provided that the total funding does not exceed the investment costs. Ask your own bank about specific combination options.
