5 Best Home Security Systems in London (2026)

Independently ranked by our review of ratings, reviews and reputation · How we chose

By Brad Smith, Home Services Expert · ✓ Data verified August 2026 · 7 min read

Home security systems in London range from national monitored-alarm chains to independent CCTV fitters who show up the next day, and the ratings here make the split obvious. SatFocus has logged 203 reviews at 4.9 stars, while Verisure, the biggest name here with 644 reviews, sits at just 3.4, so review volume alone tells you almost nothing about who actually gets the install right.

Short answer: SatFocus and Secure House Ltd both hold 5.0 or near-perfect ratings, with SatFocus the deeper track record at 203 reviews (4.9 stars). National chain Verisure has the most reviews at 644 but the lowest rating on this page at 3.4, driven largely by cancellation and billing complaints. Independent installers here typically offer a free site survey and quote before any work begins.

How we score

Every number on this page comes from public Google data as of the date shown, not opinion or payment. Rating is the business’s live Google star average. Review volume measures how many customers have rated them, ranked against other London home security providers. Confidence weighs the rating by that volume, so a 4.9 built on hundreds of reviews carries more weight than a 4.9 built on a few dozen. Recency reflects how recently customers are still leaving reviews. No business can pay to change these numbers.

How much does a home security system cost in London? (2026)

Costs vary significantly between a one-time installed system and a subscription-based monitored alarm. Several of the independent installers on this page offer a free site survey and quote before any work begins, while the national monitored chain on this list charges ongoing monthly monitoring fees on top of equipment costs. Ask each provider directly whether pricing is a one-off installation fee, a subscription, or both, and read cancellation terms carefully before signing a monitoring contract.

What to ask before you choose a home security provider

Is pricing a one-off installation fee, a monthly subscription, or both?
What’s the cancellation process, and are there any early-termination fees?
Does the system include 24/7 professional monitoring, or is it self-monitored?
How long does installation typically take?
Is the equipment mine to keep, or does it remain the company’s property?

Frequently asked questions

How did you choose these London home security providers?

We started from home security providers 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 public Google data. 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.

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.

What’s the difference between a monitored alarm and a self-installed CCTV system?

A monitored alarm connects to a 24/7 monitoring center that can dispatch a response, typically at a monthly subscription cost. A self-installed CCTV or alarm system gives you direct control without ongoing monitoring fees. Providers on this page offer both models.

Which provider specializes in bespoke security doors?

Secure House Ltd specializes specifically in bespoke high-security doors, windows, and shutters, separate from the electronic alarm and CCTV installers on this page.

The bottom line

SatFocus is the safe default for CCTV and alarm installation given its review depth and near-perfect rating, while Secure House Ltd is the specialist if physical door security matters most. Read cancellation terms closely before signing any monitored-alarm subscription.
