Private Homes
Controls should be intuitive, equipment discreet and everyday operation clear to the household. We consider the architecture and interiors alongside entertainment, lighting, security and connectivity.
Modal AV is a UK technology integration company. We bring automation, audio visual, lighting, security and network systems together around the way a space will be used
Our work spans private homes, care environments and commercial projects. We coordinate the technical detail, make the choices clear and deliver systems that are straightforward to operate, maintain and adapt.


A useful system begins with the building, the people using it and the responsibilities behind it—not with a list of products. Those conditions shape the cabling, equipment locations, interfaces, access and support model.
Modal AV works through those decisions with clients, architects, designers, contractors and internal teams. We explain the trade-offs, coordinate the technical detail and keep the finished system aligned with the original brief.
The result should feel considered in the room and remain understandable behind the scenes.
Similar technology can carry very different responsibilities. We adapt the brief to the people, routines and operational needs of each environment.

Controls should be intuitive, equipment discreet and everyday operation clear to the household. We consider the architecture and interiors alongside entertainment, lighting, security and connectivity.

Reliability, accessibility and clear staff operation shape the brief. We consider residents, care teams, communal spaces and the practical demands of maintaining technology in an occupied environment.

Systems need clear ownership, resilient infrastructure and documentation that supports operators and internal teams. We coordinate with the wider project so the technology remains manageable after handover.
Modal AV Ltd was incorporated on 5 April 2019. Billy Hilton and Costa Grigoras were appointed as directors when the company was formed and lead it today.
Modal AV Ltd · Company 11928749 · Registered office: Maidenhead, England
The company brings experience from audio visual engineering, system installation, live production and broadcast into integrated technology projects. That background shapes a practical approach: understand what the system must do, account for the realities of the site and make operation clear for the people who inherit it.
It also connects the visible experience of a space with the cabling, equipment, testing and documentation behind it.

Co-founder and Director
Costa designs Modal AV’s systems, works alongside the engineers throughout installation and remains involved when a client calls years later. He also specifies and calibrates every home cinema, carrying each room from technical planning through to its final performance. Costa moved from electrical installation into smart-home technology in 2007. That practical background still shapes his approach: every system must work as well in the finished space as it does on paper.

Co-founder and Director
Billy's background includes audio, event production and live broadcast. At Modal AV, he applies that experience to audio visual systems, integrated control and the way a finished space should perform for the people using it.
The details change with every brief.
These spaces show how lighting, audio visual
systems, control and infrastructure can be
integrated without becoming the focus of the room.
