Experience, expertise and a reputation built on recommendation

Mosaic Audio & Visual is a multiple award-winning, London-based specialist in KNX, smart home technology, building management systems, lighting control, audio-visual systems and IT infrastructure.

With 300+ successfully completed residential and commercial projects, more than 200 years of combined experience within the Mosaic team, a long-standing CEDIA membership since 2012 and accredited KNX Partner status since 2018, Mosaic has become one of London’s most experienced independent building-technology integrators.

Experience demonstrated by the numbers

Across our completed portfolio, Mosaic has integrated more than 500,000 sq. ft. of residential and commercial space. Approximately 70% of our work comes from repeat appointments and recommendations, while our engineers have installed, programmed and commissioned thousands of KNX devices during their careers.

These figures demonstrate both the scale of our experience and the confidence clients and project teams continue to place in Mosaic.

A reputation built through repeat business

A large part of Mosaic’s success has come through repeat business, client recommendations and professional teams choosing to work with us again and again.

Around 70% of our work is generated through repeat appointments and recommendation. For us, this continued confidence is every bit as important as an industry award. It demonstrates that clients, architects, designers, consultants and contractors value not only the systems we deliver, but also the way our team works throughout the design, construction and commissioning process.

Our growth has been built steadily through honest advice, technical competence, hard work and a willingness to take responsibility.

300+ successfully completed projects

Mosaic has now successfully completed 300+ projects across London and the surrounding counties. Our experience ranges from luxury private homes, apartments and listed-property refurbishments to major commercial buildings, CAT A fit-outs and fully integrated building-management projects.

Every completed project adds to our practical understanding of how lighting, heating, cooling, ventilation, shading, AV, networking and security systems must work together.

Collectively, these projects represent more than 500,000 sq. ft. of integrated space, including prestigious homes and developments in Belgravia, Chelsea, Kensington, Mayfair and Holland Park.

Multiple industry awards

Recognition for residential and commercial excellence

Mosaic’s industry awards reflect the breadth of our work, from beautifully integrated private homes to complex commercial building-control projects.

CEDIA Best Integrated Home Award 2025

In 2025, Mosaic’s work was recognised with a CEDIA Best Integrated Home Award. The achievement reflects the quality of our design, engineering, installation, programming and project delivery.

A genuinely successful smart home should feel natural to use. Lighting, climate control, entertainment, networking and security should work together without the property feeling dominated by technology.

The award also recognises the importance of collaboration. The strongest integrated homes are created when technology is considered alongside architecture, interior design, mechanical services, lighting and construction.

KNX UK Best Commercial Project Award 2022

Mosaic received the KNX UK Award for Best Commercial Project of the Year in 2022 for the delivery of a major 130,000 sq. ft. full CAT A refurbishment. Mosaic provided the complete BMS, audio-visual, lighting-control and IT integration for the project.

Delivering a building of this scale required detailed system design, panel engineering, software development, testing, commissioning, documentation and close coordination with the consultant and construction teams.

This 130,000 sq. ft. member-space office refurbishment remains our largest commercial KNX project to date.

Control4 Award winner at Integrated Systems Europe

Mosaic has also been recognised as a Control4 award winner at Integrated Systems Europe, one of the world’s leading exhibitions for professional audio-visual and systems-integration technology.

Our Control4 experience allows us to bring entertainment, lighting, climate control, security and connected technology into a straightforward user experience. Combined with our KNX, Lutron, AV and networking knowledge, this enables Mosaic to deliver a truly coordinated solution.

London KNX experience

One of London’s most experienced KNX integrators

Mosaic has been an accredited KNX Partner since 2018 and provides complete KNX design, engineering, programming and support throughout London and the surrounding counties.

KNX is an internationally recognised building-control standard approved as ISO/IEC 14543-3. It provides a dependable and flexible platform for integrating lighting, heating, cooling, ventilation, shading and energy management.

Because KNX is an open global standard, clients are not tied to a single manufacturer. Products from a wide range of established manufacturers can be selected to suit the building, design requirements and budget.

Our experience enables us to design KNX systems that are practical, robust and maintainable.

More than a KNX programmer

Mosaic does not treat KNX programming as an isolated service. We understand the wider building-services and technology environment, including HVAC plant, underfloor heating, fan-coil units, lighting drivers, shading, energy monitoring, AV control, wired networks, Wi-Fi and security integration.

This broader knowledge is particularly valuable on complex London properties, where space is limited, finishes are highly detailed and several specialist contractors must coordinate their work.

Our team brings more than 200 years of combined industry experience, allowing younger engineers to work alongside highly experienced designers, programmers and project managers.

One experienced team across BMS, AV, lighting and IT

Modern properties depend on several connected technologies. Mosaic’s strength is our ability to understand how those systems interact and coordinate them as one complete package.

Our integrated services include:

KNX building management and environmental control
Smart home automation and Control4 integration
Lutron lighting and automated shading
Heating, cooling and ventilation control
Multi-room audio, television and cinema systems
High-performance wired networks and managed Wi-Fi
CCTV, access control and door-entry integration
Energy monitoring, remote access and intelligent system management

By coordinating these disciplines, Mosaic can reduce gaps between contractors, improve design clarity and simplify responsibility for the client. Our objective is not to add unnecessary complexity. It is to select appropriate technology and make it work reliably as part of the building.

Trained, experienced and fully insured

Mosaic projects are delivered by trained and experienced designers, project managers, engineers and programmers with more than 200 years of combined industry experience.

We maintain strong relationships with the manufacturers whose products we specify, giving the Mosaic team access to product training, current technical information and direct manufacturer support.

We are fully insured and accustomed to working as part of a professional project team. We understand the importance of accurate quotations, coordinated drawings, programme commitments, site communication, testing records, commissioning information and a thorough handover.

We do not simply supply and install equipment. We take responsibility for understanding the brief, coordinating our scope, identifying technical issues and helping the wider team reach the right outcome.

An honest and hardworking partner

Awards, accreditations and completed-project numbers provide valuable reassurance, but our reputation ultimately depends on how we treat people.

We provide straightforward advice, explain the available options and recommend systems that are appropriate for the property. When a challenge arises, we work constructively with the project team to find a solution.

Our willingness to support clients beyond the immediate installation is equally important. Buildings evolve, families’ requirements change and technology develops. A well-designed system should provide a strong foundation, and the integrator should remain available to help it adapt.

Designed for the way people live and work

Technology is only successful when it improves the building for the people using it. Our systems are designed around real routines, comfort, convenience, energy use and long-term reliability.

Controls should be intuitive, interfaces should be clear and essential functions should continue to work dependably.

For residential clients, that may mean a home where lighting, temperature, music and security are simple for every family member to use. For commercial clients, it may mean efficient environmental control, clear monitoring, adaptable workspaces and a system that facilities teams can manage confidently.

Early involvement creates better projects

The best results are achieved when Mosaic is involved at an early design stage. Early coordination allows the BMS, lighting, AV, networking, security and control requirements to be considered before construction decisions restrict the available options.

We can work directly with the client or alongside architects, interior designers, developers, M&E consultants, quantity surveyors and main contractors.

Our role is to provide clear technical information, protect the design intent and ensure the technology package is properly coordinated from concept through to handover.
