How we score

Every number on this page is computed from public Google data on the date shown, not from opinion or payment. Rating is the business’s live Google star average. Review volume is how many customers have rated them, ranked against other London home automation companies. Confidence weighs the rating by that volume, so a 4.9 from over 200 reviews carries more weight than a perfect score from a smaller base. Recency reflects how recently customers are still leaving reviews. No business can pay to change these numbers.

How much does home automation cost in London? (2026)

Pricing for smart home automation in London depends heavily on the scope, from a single-room lighting or AV setup to a full whole-home Control4 or Crestron integration, and none of the companies on this page publish a fixed public rate we can verify. We are not printing figures here. Ask each company for a site visit and written quote based on your specific requirements.

Serving all of London

The companies above cover Harrow, White City, Wembley, Westminster and Fitzrovia, with several serving Greater London and beyond. Searching for a home automation installer near me? Every listing below shows a live phone number so you can check current availability and coverage for your address.

What to ask before you hire a home automation installer

Which system platforms do you work with, such as Control4, Crestron or Lutron?
Do you offer ongoing support and maintenance after installation, and what does that cost?
Can you provide a written quote before starting, with no surprise add-ons?
How do you handle emergency call-outs if something stops working?
Will the system integrate with equipment I already have installed?
Do you offer training so I can manage basic settings myself?

Frequently asked questions

How did you choose these companies?

We started from every home automation and smart home company in London with a public Google presence, then ranked by rating, review volume, consistency, and recency. See How we score above.

Are these rankings paid?

No. Rankings come from the public Google data in the scorecard. A business can pay to be a Featured Partner, which adds a badge and top placement, but that never changes another business’s score or position on the underlying data.

How often is this updated?

The data carries a verified date (August 2026 on this page). We refresh listings periodically so ratings and review counts stay current.

Which company is best for Control4 support specifically?

London Smart Homes and Avitha both have detailed, specific reviewer praise around Control4 troubleshooting and installation.

Is SatFocus a dedicated smart home automation company?

SatFocus is primarily a CCTV, alarm and networking installer that also covers some automation and networking work. For a full whole-home Control4, Crestron or Lutron system, IntelliCasa, London Smart Homes, Avitha or Liv Technology are closer specialists.

The bottom line

SatFocus is the safe default if your needs center on CCTV, alarms and general networking, while IntelliCasa and London Smart Homes are the stronger picks for a full, bespoke smart home build with Control4, Crestron or Lutron. Whichever you choose, get a written quote covering ongoing support before you commit.
