Onsite IT Support in London

Many IT providers offer unlimited onsite IT support as part of their contracts. However, here’s the reality: most businesses rarely need it. With today’s advanced remote support capabilities, many technical issues can be resolved without the need for IT engineers to visit your office. Paying for unlimited onsite support services might seem reassuring, but in most cases, it’s an unnecessary cost. 

As an experienced IT service provider, Sereno offers a practical, cost-effective approach: onsite IT support only when you need it, ensuring you get expert help without overpaying for services you hardly use.

When You Need Onsite IT Support

For day-to-day troubleshooting, remote support is often the fastest and most cost-effective solution. We can usually resolve issues within minutes without the need for an onsite visit. However, onsite support is recommended in the following scenarios:

Hardware Failures

Replacing faulty devices, fixing servers or repairing networking hardware.

Network Setup & Troubleshooting

Configuring routers, switches and cabling to ensure smooth operations.

Security Measures & Compliance

Physical security checks, security patches and compliance audits.

Office Moves & IT Upgrades

Seamless relocation or upgrading of IT infrastructure.

In-Person Support & Training

Helping employees with new systems and technology.

The Smart Way to Use Onsite IT Support

Rather than paying for unlimited visits, we recommend a flexible IT support plan that includes:

Remote First, Onsite When Needed

Most IT issues can be resolved quickly and efficiently with remote support. However, when complex issues arise, such as hardware failures or network outages, onsite visits are unavoidable. Our support team comes to your location to diagnose and fix the problem in person. 

Scheduled Preventative Visits

Why wait for things to go wrong? A preventative approach helps address potential issues before they grow into major problems. Scheduled visits allow our onsite team to regularly assess and fine-tune your IT infrastructure. From updating software to implementing backup solutions, our IT specialists keep your systems in top shape.

Affordable Ad-Hoc Onsite Support

Sereno offers affordable, pay-as-you-go onsite IT support services. If something comes up that can’t be solved remotely — like a technical emergency or a larger issue that requires hands-on attention — you only pay for the time and services you actually need.

Scalable IT Solutions

Every business has different IT needs, which is why our onsite IT services are designed to scale with you. For example, we provide more frequent visits to companies with growing teams or expanding networks. Conversely, if you’re a smaller operation with minimal IT requirements, we can scale back and offer support on a less frequent, as-needed basis.

Why Our Clients Love This Approach

Cost-Effective

No wasted money on unused onsite visits.

With a hybrid IT support model, you’re only paying for what you actually need. Remote support handles most issues quickly, keeping costs low. When an onsite visit is necessary, you get expert assistance without the extra cost of maintaining full-time IT staff.

Fast Resolutions

Remote support fixes issues in minutes.

Remote support is your first line of defense. Most technical problems, from software bugs to network issues, can be diagnosed and resolved within minutes. Our IT specialists connect securely to your systems, troubleshoot the problem, and get everything running smoothly again, all without disrupting your workflow.

Proactive IT Management

Regular IT checkups prevent problems before they happen.

Fixing IT issues as they occur is one thing, but preventing them in the first place is even better. Regular system checkups, software updates, and security monitoring ensure that small problems don’t turn into major disruptions.

Local Onsite Engineers

Available when hands-on support is truly needed.

Sometimes, there’s no substitute for an onsite visit. When you need to replace a failing hard drive, troubleshoot complex network issues, or set up new office equipment, we are ready to assist.

I have known Sereno (and their previous business) since 2016 as they are the IT solutions providers of our private credit fund with complex operations. Sereno are exceptional in solving issues in a prompt manner. Most recently I have dealt with Sahaj who set me up on the company IT infrastructure within few hours which can take days in a similar business with the complexity that the fund has. Furthermore, Sahaj resolved more issues for me with 2fa, mobile and security set-ups. Team members are available as soon as an issue pops up and generally relationship is managed by a single person making things streamlined with the single person with all knowledge of issues and set-ups to date. I would highly recommend Sereno based on my personal experience of them solving multiple problems for me at the credit fund.

My company moved to Sereno IT over the new year and we have found the process not only to be painless but i would describe it as enjoyable. They have kept me and my team updated and in the process managed to save us money by developing our systems and removing unnecessary expenses on services that were no longer required. Great to find a partner that proactively works in the background with the best interests of my company at the forefront of their work.

We have been clients of Sereno IT's since summer 2023 and we have been extremely happy with the service we have received to date. Sereno have built their business with a direct aim to fix the issues that are notoriously problematic with MSPs, and having experienced some of these problems with our previous MSP, Sereno are truly achieving in their efforts.

Everything is so streamlined and easy for clients to use - their partner portal has truly thought of everything, from ordering IT equipment, to scheduling calls with engineers. The team always make sure everything is very clearly explained, and when things are a little more technical/ difficult to put into an email, we have received personal video explanations which have been so useful.

Highly recommend Sereno's services!

These guys are new in the market, but they provide outstanding service service. What is important to our company, that they comprehend hierarchy of team and therefore importance despite the issue is applied. When we need something urgent, they find a manpower to resolve it asap. And most important for me as an assistant, i don't have to have IT language to explain the issue, they know issue is there and they find it and fix it - i do not have to answer 10 questions if i have done this or that, but they fix it by jumping on the system, with in short time all is done and you can move on with your day. And they are always positive 🙂

We have been a customer of Sereno since Summer 2023 and the experience since has been overwhelmingly positive. We are an SMB working in a complex, safety-critical industry, where stable and reliable IT services are paramount. Sereno have never let us down, with their team of highly competent, customer-focused technicians, who always go the extra mile.

As well as high quality services, they are also proactive in identifying areas for improvement and where they can add value. Compared to many other traditional IT suppliers, they are interested in establishing a true partnership, where the needs of both parties are taken into consideration.

I really can't recommended Sereno IT highly enough, as the other 5* reviews on here will also testify.

Great company, full of energy and very attentive to our needs. You really get a personalised service, with the technical ability of a much larger company.

My business has recently adopted Sereno IT Support as our ITSM partner over the last quarter. This has been a sensible move for us as we scale, and the moving parts will become more complex as we grow. I have experienced a few issues, but these have been quickly addressed. One particular, tricky item involving my work mobile was a challenge - but, “We got there in the end! Thank you Tamim - your support has been very helpful and much appreciated”

Excellent, speedy, friendly and very 'human' service. Intuitive and easy to use platform. I'm the type of person who normally puts off raising IT tickets but Sereno has actually changed that for me because it's so easy and straightforward, and everything gets actioned quickly.

I've had the pleasure of working with Sereno for several months now, they are honestly absolutely fantastic. The service really is better than I have experienced from other support organisations.

The team is incredibly easy to work with. Everyone I have interacted with is friendly, seems to listen and is generally responsive. They also have a high level of understanding of industry specific problems which helps a lot.

We've has issues in the past with really slow response times but this an area where Sereno does really well. We're usually able to get an answer to queries within minutes, and resolutions within hours at most.

We have also used them for advisory services on security and are really happy with the results. It's been a much more efficient process than the in house team we have previously.

Highly recommend!
