By Linus Palmqvist, Head of Operations Reviewed by Simon Nilsson Last reviewed Sector Alarm runs its own monitoring centre in Mijas and bought ADT Spain in 2026, so it now sells under both names. It rents you the equipment rather than selling it, and asks for one month of notice at renewal.
One of the best reviewed of the six, though the equipment stays theirs rather than becoming yours.
The facts worth knowing before you talk to them, and the ones you can check yourself.
Sector Alarm absorbed the ADT Spain business in June 2026 and now contracts for both.
No published monthly rate. Ask for the opening and standard figures in writing.
That is where the centre is, not a statement of where they install. Check your address.
The equipment stays theirs unless you take a purchase option at the end.
Notice is one month before the renewal date. Deferred setup costs can fall due if you leave early.
A callout is a separate service. Timing depends on traffic, workload and distance.
The name that should appear on your contract. Registered as DGP 1557.
Go to Sector Alarm yourself, or let us handle the Spanish side. Both work.
Free, and you are not committed to Sector Alarm.
Straightforward to sign up with. These three are the ones worth pinning down first.
Someone attending the property is a separate service here. Ask whether your quote includes it, and what each visit costs if not.
It stays theirs unless you buy it at the end. Ask what you would return, and what the purchase option costs.
Setup costs can be spread and then brought forward on termination. Ask for the figure at month 14.
Sector Alarm publishes manuals and forms in English, and serves customers across several countries.
Available in English, so the paperwork around the system is readable.
No company in this market promises an English-speaking operator when an alarm goes off. Plan on that conversation being in Spanish.
Spanish, like every alarm contract here. That is the part we do with you.
Worth reading a few yourself rather than going on the number alone.
around 11,000 reviews. One of the highest scores of the six. Checked 25 July 2026.
The service and the installers review well. The app is the weak point, and it scores noticeably lower in the app stores than the company does on Trustpilot.

Head of Operations at Settlewell
Linus moved from Sweden to Málaga in 2021 and set his own home up here, so most of this he has already done the hard way once. Before Settlewell he spent years at Workwide, the cross-border recruiter that has helped over 10,000 people into jobs abroad, latterly as its Head of Recruitment and Operations. He speaks Spanish, lives in Málaga with his partner, and spends his days on the phone to Spanish providers.
Company identity and registration come from the national register of security companies, and the merger from the official BORME filing. Contract points come from Sector Alarm published general terms, and review figures are a dated snapshot from one named platform.
