Who are the best smart home installers in London?

Custom Controls are one of London's most experienced and most awarded smart home installers, with 25 years of Crestron and Lutron installation experience, five consecutive Crestron Integration Award wins and Crestron Dealer of Distinction status.

How much does a smart home installation cost in London?

A single-system Lutron lighting installation for a London home starts from approximately £8,000. A whole-home Crestron and Lutron system for a substantial London townhouse typically starts from £60,000 and can reach £150,000 or more for complex multi-floor properties.

Can you take over an existing smart home system in my London property?

Yes — smart home system takeovers are one of our most common London services. We audit the existing installation, diagnose faults, reprogramme to our standard, replace outdated hardware and enrol the system in our remote monitoring service.

Do you offer smart home support and maintenance in London?

Yes. Every Custom Controls smart home installation is enrolled in remote monitoring from day one. We offer annual maintenance contracts for London properties with scheduled visits, software updates and priority response, and pay-as-you-go support for properties without a contract.

Can a smart home system be retrofitted to an existing London property?

Yes. Crestron retrofits well into most existing properties. For lighting, Lutron RadioRA 3 is fully wireless — no rewiring required. It is our standard recommendation for retrofit projects in London's period properties and listed buildings.

Do you install smart homes in listed London properties?

Yes. We select wireless Lutron lighting control, plan all cable routes to avoid damage to historic fabric, and work with conservation officers where required. Our installations in listed London properties are reversible and leave the historic fabric untouched.

Smart Home Installer London — Crestron & Lutron Home Automation

London’s most experienced smart home company. Certified Crestron Dealer of Distinction & Lutron dealer since 1998. Design, installation, programming & ongoing support.

Custom Controls are a London-based smart home installer and home automation company with 25 years of experience delivering bespoke Crestron and Lutron systems for luxury residential properties across the capital. We are five-time Crestron Integration Award winners and hold Crestron Dealer of Distinction status — one of a very small number of London smart home installers with this credential. Our London office is in the City of London, EC2V, and our engineers are active across all prime London residential postcodes and the wider Home Counties.

We do not offer smart home as one service among many. It is the core of everything we do — and has been since 1998. Every system we design is bespoke, every programme is written from scratch, and every installation is pre-built and tested at our workshop before arriving on site.

Smart Home Installation in London — What We Deliver

Crestron Home Automation. The central intelligence. Crestron manages everything — lighting, AV, climate, security, access and blinds — from a single bespoke interface. We install both Crestron Home (faster deployment, ideal for most London residential projects) and Crestron Custom (fully bespoke programming for complex multi-floor or multi-building projects).

Lutron Lighting & Shading. Lutron Homeworks QSX for new builds and major London renovations. Lutron RadioRA 3 — fully wireless, no rewiring — for retrofit projects in existing London homes, period properties and listed buildings. Sivoia motorised blinds and curtains for privacy, solar gain management and scene control.

Whole-Home Audio Video. Any source to any room in the London property. Crestron NVX for 4K video distribution; Crestron NAX or Bluesound for multi-room audio; Kaleidescape for reference-quality cinema source material; Sonos for streaming convenience in every zone.

Home Cinema. Dedicated cinema rooms, living room cinema systems and media rooms — acoustically designed, installed and calibrated by our own team. We specialise in basement cinema rooms, living room retractable screen systems and loft cinema conversions across London.

Enterprise WiFi & Network. Ubiquiti UniFi or Cisco Meraki access points on a wired PoE backbone, with VLAN segmentation separating smart home, personal, security and guest traffic. Essential for London townhouses with thick masonry construction and basement levels.

Security & Access Control. CCTV, video intercom, intruder alarm and smart access control integrated within the Crestron system. For London properties with multiple entry points — front door, tradesman’s entrance, basement access, garage — Crestron manages each with individual credentials from a single interface.

Smart Home System Takeovers London

London has a significant concentration of smart home systems installed by companies that have since closed, moved on or been unable to continue supporting their installations. System takeovers are a major part of our London workload. We audit the existing system, diagnose what is working and what is not, reprogramme to our standard, replace outdated hardware where necessary, integrate previously disconnected systems into a unified interface and enrol the system in our remote monitoring service. If you have a smart home in London that is underperforming, partially broken, or no longer supported by the original installer, contact our London office.

Smart Home Support & Maintenance London

Every smart home system we install in London is enrolled in our remote monitoring service from day one. We receive automatic alerts when any element of the system degrades and resolve the majority remotely before the client notices anything. We offer annual smart home maintenance contracts covering scheduled preventative maintenance visits, software updates, programming refinements, system health checks and priority response. Our London support clients include some of the most technically complex residential installations in the capital — systems we have been actively maintaining since the early 2000s.

London Smart Home Case Studies

Primrose Hill, London

A complete Crestron Digital Media smart home installation across a six-storey north London townhouse. Crestron NVX video distribution to nine rooms, multi-room audio across eight zones, Lutron Homeworks QSX lighting throughout, full security integration with video intercom distributed to every floor and a Crestron touchpanel on each level. One of our most complete London townhouse installations and a reference point for what Crestron and Lutron deliver together in a large residential property.

Baker Street, London

The first Crestron Digital Media installation in the UK, delivered by Custom Controls and subsequently expanded across multiple project phases over more than fifteen years. Kaleidescape movie servers, full CCTV integration, a redesigned control interface, new multi-room audio and a complete Lutron lighting rework across multiple renovation stages. A project that illustrates both the longevity of a well-designed Crestron system and the depth of the client relationship that a committed smart home installer sustains over time.

Claridge’s Hotel, Mayfair

A Crestron installation in a Claridge’s suite, delivered to the exacting standards of one of London’s most prestigious hotels. AV control, lighting management and system integration within an active luxury hotel environment. Awarded Best Commercial Project at the Crestron Integration Awards — one of the five consecutive award wins that earned Custom Controls its Dealer of Distinction status.

Canaletto Tower, City Road

A system takeover and upgrade in a high-specification City Road apartment. The original developer-installed Crestron system was frustrating to use and poorly maintained. We replaced the control interface, reprogrammed the system, added Origin Acoustics audio, full HVAC integration and enrolled the property in remote monitoring. The client describes the experience of using the system after the upgrade as entirely different from living with it before.
