The challenge: Southern Housing needed to bring 33 Independent Living Schemes through the UK PSTN digital transition, replacing or upgrading legacy warden call and door entry infrastructure before analogue connectivity is switched off. With residents living in every scheme throughout the works, the programme had to deliver full system replacements and digitalisation upgrades without compromising resident safety, comfort or day-to-day routine.

Our approach: We structured the programme as two parallel streams: complete system replacements at designated properties and targeted digitalisation upgrades at others - in both cases installing Tynetec Advent XT2 systems with KMS Cloud Access Control. Every scheme's existing cabling infrastructure was assessed against 18th Edition IET Regulations; where routes met performance and safety standards, they were retained and integrated, reducing disruption within occupied schemes while maintaining full compliance. Temporary pendant coverage was provided throughout to maintain resident safety at every stage of the works and each scheme underwent full testing, commissioning, staff training and O&M handover before sign-off.

What we delivered under this contract

• Complete removal and replacement of legacy warden call and door entry & access control systems

• Structured cabling upgrades compliant with 18th Edition IET Regulations

• IP Digital Communicator integration to Alarm Receiving Centres

• Full IP DECT deployment ensuring 100% site coverage

• Temporary pendant coverage to maintain resident safety during works

• Full testing, commissioning, training and O&M handover

• Retention and integration of existing cabling routes where compliant, minimising disruption in occupied schemes

The programme achieved 618 flat installs, with schemes now successfully completed and operating on modern, IP-ready life safety systems. Resident satisfaction feedback across more than 500 completed survey responses has consistently reflected high levels of customer satisfaction, particularly around engineer professionalism, quality of workmanship, communication and resident engagement during works in occupied schemes.

Client feedback consistently recognised S.E.A Limited's ability to deliver complex warden call and digital upgrade works within live, occupied environments while maintaining high standards of professionalism, communication and resident consideration - with particular praise for engineer conduct on site, cleanliness of completed works and the collaborative approach taken throughout.
