CSS LTD have been invited to Italy for a technical visit

CSS LTD can provide smart home security systems that are tailor made for each customer at their budget

Mr Ian Bradley

Simply the best

We required a new intruder alarm system to replace the existing obsolete one. Contacted Tony Leck of Complete Security Systems and he promised to get a quote over the same day and he did exactly that with a smart home security price which we were very happy with. CSS LTD gave a installation date and installed it as per the date. The system has a smart App and completely wireless system which we are really happy with and glad we switched to CSS LTD, well done lads keep up the great work and service.

Our existing intruder system needed a new service provider due to the existing maintenance contract was ending. We contacted CSS LTD which responded same day with a new intruder alarm and monitoring package price with Police Response. CSS LTD took over the system with a new monitoring system and we are very happy with their service and speed they completed the takeover without any loss of cover. Highly recommend this company.
