How Our Emergency IT Support Service Works:

Immediate Contact: As soon as you experience an IT emergency, contact our computer emergency support team on 020 3005 4440 or email us at
Initial Assessment: Our team of experienced IT professionals will perform an initial assessment to understand the severity and nature of the issue. This helps us determine the appropriate level of urgency and resources required to address the problem effectively.
Remote Assistance: In many cases, we can resolve IT emergencies remotely. Our team will use secure remote access tools to troubleshoot and fix the problem directly on your affected devices or systems. This approach allows us to address the issue without any delay, saving valuable time.
On-Site Support (if required): If the issue cannot be resolved remotely, we will dispatch a team of skilled technicians to your location for on-site support (available to London, Essex, Cambridgeshire clients). Our technicians come prepared with the necessary tools and expertise to diagnose and fix the problem promptly.
Continuous Monitoring: Once the initial emergency is resolved, we don't stop there. Our computer emergency support team will continue to monitor your systems closely to ensure there are no lingering issues or potential vulnerabilities that could lead to future emergencies. Proactive monitoring helps prevent future disruptions.
Documentation and Reporting: Throughout the entire process, we keep detailed records of the emergency and the steps taken to address it. After resolving the issue, we will provide you with a comprehensive report that outlines the incident, the actions taken, and any recommendations for preventing similar emergencies in the future.
Follow-up and Customer Care: Our team will follow up with you to ensure that everything is running smoothly after the emergency resolution. Note that we also offer IT support 24 hours per day and remote monitoring services for IT systems.

Commonly Questions Answered

What is emergency IT support?
Emergency IT support provides rapid assistance to address critical issues in a computer or network. A good provider will resolve urgent technical problems promptly, ensuring minimal downtime and preventing disruptions to business operations. An emergency IT support service will deal with unexpected IT emergencies such as system failures, data breaches or network outages.

Our emergency IT support phone number is 020 3005 4440.
How quickly can I expect a response when facing an IT emergency?
We’ll typically respond within 30 minutes and solve critical issues within two hours. Depending on your issue, we resolve problems either remotely or onsite for clients in the southeast.
Why is a disaster recovery plan essential for businesses?
A disaster recovery plan (DRP) is a step-by-step guide revealing what to do in the event of a crisis. It is essential for businesses as it ensures continuity, protects data from loss, mitigates risks, meets compliance requirements and provides financial protection by minimising downtime.

However, we won’t leave you high and dry if you don’t have one in place. We’ll work to get you up and running as quickly as we can. We’ll also provide you with some advice on setting up a DRP, to protect you in the future.
How can I ensure my data is properly backed up?
This is the right question to ask. Ensuring you have your data backed up could save you from a world of pain in the event of an IT emergency. Steps to take include:

Identifying a data manager within your organisation, to take responsibility for back-ups.
Understanding your data loss risk.
Identifying clear objectives for your data back-up plan.
Following the 3-2-1 rule: Make at least three copies of the data; use two different storage formats; ensure at least one copy is stored offsite.

Intersys offers complete cloud backup services including disaster recovery. We've also written a useful blog post about why you must start your business data backup plan now.
How do you ensure data safety during an emergency?
Ensuring data safety during an emergency involves following data integrity best practice. Intersys is an ISO 27001-certifed cyber security and IT compliance expert. All of our team undergoes appropriate training in data handling and follows tried-and-tested procedures for data recovery.
