Professional service - Always quick to respond to call outs and always prompt with routine maintenance. Engineers always thorough and answer any questions.

Polite friendly engineer left the premises clean and tidy

Have been using this company for years and always arrive early / on time for annual maintenance. Today had an upgraded alarm fitting which went well. Paul was very professional sorting out the installation and walking me through the operation. Happy to recommend them to others.

We have been with Mercury for years. They are always on time, fixes anything that goes wrong last minute and are very competitively priced. The guys that come out on call outs are friendly and better still - know what they are doing! I would going anywhere else for my security needs.

Had a CCTV system installed on our office premises. Mercury were brilliant from start to finish. highly recommend

Had to call out due to alarm bell fault. Quoted a price for call out that doubled yes doubled when invoiced. We seem to having to pay for engineer not knowing what engineer code had been set by previous Mercury engineer. Then claimed other faults with system which were ok until Mercury attended, engineer basically said system needs to be completely changed then spent time checking what we had to organise quote. Best not to use this company as appear to inflate charges and do not resolve issue other than to suggest a totally new system, what a surprise!! Use this company at your peril

Very poor alarm systems and customer service. We purchased our alarm in November 2014. We have had the alarm serviced annually for each of 7 years. We have had to call them out, on an additional 4 occasions for further work, in year, because they have either failed to carry out the service properly or faults have occurred. On the last two occasions we have made appointments for repair (again) in July and service in December. On both occasions they have contacted me, on the morning of the appointment and asked to reschedule, because the engineers were unwell. On the first occasion I agreed to reschedule and was very understanding. On the second occasion my husband had taken time off work, in order to discuss issues with the engineer. The company accepted no responsibility for, their failure, to send an engineer at the agreed time. There is obviously no contingency planning or consideration for any inconvenience caused to the customer, for their failings. I will take my business elsewhere.
