💡 *A little light when you need it most*

With the mornings getting darker and the evenings drawing in, outdoor lighting becomes useful for much more than simply illuminating a property.

PIR security lights detect movement and automatically provide light when it’s needed, whether that’s helping you find your way to the front door, lighting a driveway or pathway, or providing an additional security measure around your home or business.

Simple, practical and particularly useful at this time of year.

Welwyn Garden Alarms can supply and install PIR security lighting as part of a wider approach to protecting your property.

Gemma at Hyfire had a great a new idea… and Pete was unfortunate enough to be the first victim. 😂 Gemma wanted to find out a bit more about the people behind the Hyfire partners, their career, their journey, the lessons they’ve learned… So obviously, I put Pete Goodchild of Welwyn Garden Alarms on a ladder and started asking questions. 🤣

Because why have a normal business chat when you can take it to new heights? 👀

⭐⭐⭐⭐⭐ From first estimate to final fix

Home refurbishment projects do not always run to plan, so it means a lot to receive feedback like this from a customer whose project stretched over 18 months. Thank you for the kind words and, especially, for continuing to recommend us to others. That really is one of the best compliments we can receive.

We are proud to have established a strong and ongoing relationship with Wheatley Homes, supporting their developments through the delivery of reliable, compliant and professionally installed fire and security systems.

Working closely with Wheatley Homes and their wider project teams, we provide a complete range of fire and security solutions designed to meet the specific requirements of residential developments. Our involvement covers the design, supply, installation, commissioning and ongoing support of systems, ensuring that each development is delivered to the required standards and provides residents with a safe and secure environment.

Our approach is based on collaboration, quality and consistency. We work closely with Wheatley Homes throughout each stage of a project, from initial requirements and coordination through to completion and handover. This enables us to identify potential challenges early, coordinate effectively with other contractors and ensure that systems are installed efficiently with minimal disruption to the wider construction programme.

Through our continued relationship with Wheatley Homes, we have developed a clear understanding of the standards, expectations and practical requirements associated with their developments. This experience allows us to provide a responsive and dependable service, while maintaining a strong focus on compliance, workmanship and long-term system performance.

We see our relationship with Wheatley Homes as a long-term partnership rather than simply a contractor arrangement, and remain committed to supporting the successful delivery of safe, secure and high-quality homes across their developments.

🌙 The darker evenings are starting to creep in...

As autumn approaches and the evenings get shorter, it’s a good time to make sure your home security is working exactly as it should.

That might mean checking your intruder alarm, making sure CCTV cameras still have a clear view, testing security lighting or simply reviewing whether your current system still suits the way you use your home. A few small checks now can help make sure everything is ready for the darker months ahead.

If you’re unsure about your existing alarm or CCTV system, or think it might be time for a service or upgrade, the Welwyn Garden Alarms team is always happy to help.

⭐⭐⭐⭐⭐ Knowledgable, friendly and efficient

Moving into a new home can come with plenty to get used to, including an alarm system you’ve never seen before.

We were really pleased to receive this feedback from a customer who contacted us to service their existing system and help them understand exactly how everything worked.

Taking the time to explain each sensor, answer questions and make sure our customers feel comfortable using their security system is an important part of the service we provide.

And, as they discovered after an accidental activation, knowing there’s someone there to respond quickly can provide a little extra reassurance too!

Thank you for the fantastic feedback. It’s always appreciated.
