Frequently Asked Questions
Answers to common questions about choosing and working with an IT support company in London.
Reliable managed services give businesses access to expert support without the cost of assembling a full in-house IT team. Sereno helps with day-to-day issues, ongoing IT management and longer-term planning, with support that can be adapted to your business needs.
Sereno puts your experience at the centre of IT support, rather than judging good service by response times alone. Our Customer Experience Agreement (CXA) measures how well we communicate, take ownership and resolve issues, based on feedback from your team. We also look beyond individual support requests, fixing recurring problems and providing proactive guidance through a dedicated Technology Advisor.
Yes. Sereno offers fully managed IT support and can work as your outsourced IT team, taking ownership of day-to-day support, IT admin, cyber security and ongoing management. This takes routine IT work off your CTO or founder while still giving them access to advice when important technology decisions need to be made.
Sereno’s service desk prioritises quick response times and minimising disruption. Around 75% of issues are fixed remotely within minutes, while more complex problems are passed to experienced engineers for further support.
The cost of IT support depends on your team size, current setup, security needs and the level of support you require. Sereno offers fixed monthly pricing tailored to your business, so you know what is included before you get started. Any on-site support, projects or one-off work is agreed upfront. See our IT support pricing for more information.
As a London company, we support businesses across the whole of London and its outer areas. We also work with UK companies that have a London office or branch and need a local managed IT service provider for hands-on support.
Sereno helps make sure your IT keeps pace as the business grows. We streamline onboarding, offboarding and device management, while your support can flex with your headcount month by month. Every quarter, your dedicated Technology Advisor reviews your IT environment, service performance, cyber security and assets to identify priorities, reduce risk and keep your technology roadmap aligned with the business.
We use remote support as the most cost-effective first step, with 75% of IT issues resolved remotely. If an issue cannot be fixed remotely, we arrange scheduled on-site support to resolve it in person.
Yes. Sereno works with remote and hybrid teams, providing day-to-day user support for employees working from different locations.
Sereno streamlines onboarding and offboarding so accounts, licences, devices and access are set up or removed consistently and on time. Automation around device builds and employee changes reduces manual admin and helps avoid delays. For new starters, a dedicated onboarding engineer manages the process end to end, making setup as smooth and non-disruptive as possible.
Sereno is Cyber Essentials certified at Plus level, demonstrating that its security controls have been independently verified. Our cybersecurity services include endpoint protection, email security, secure configurations and ongoing monitoring to help safeguard your business data.
