1. CloudTech 24
Address: 36 Albert Embankment
Phone: +44 20 7099 0740
Business hours: Available 24/7
What sets CloudTech24 apart from competitors is its 24/7 support. It’s reassuring to have reliable people who can help your team when something unexpected happens during your daily operation at any time of day or night.
Another great aspect of them is their comprehensive IT support services. They can support platforms, including Google Cloud and Microsoft 365. Some of their services are Google Workspace support, server support, and website hosting.
What’s even better is that they have extensive cybersecurity support services. They offer advanced domain security, firewall security audit, and more. With them, your business would be highly protected from cyber threats.
Last but not least, we appreciate their responsiveness. They replied to all our questions in a very timely manner. Combined with their 24/7 support, this provides peace of mind that we all want.
The only drawback is that they only offer commercial IT support services. They don’t have a single service dedicated to a household.
They have exceeded our expectations
“I cannot recommend CloudTech24 highly enough. We’ve worked with various members of the team at CloudTech24 on different projects for some time, and they are always professional, knowledgeable, friendly, and patient whatever the subject or issue.

In summary, our all-round experience with CloudTech24 has been excellent – they have exceeded our expectations, and become a valued strategic partner.”

Thank you for such outstanding support
“Ethan from CloudTech 24 was absolutely fantastic! Despite only receiving the brief moments before our call, he came fully prepared and handled everything with incredible professionalism.

I cannot recommend Ethan and CloudTech 24 highly enough. Their expertise will save you time, money, and countless headaches! Thank you for such outstanding support!”

2. Solid Rock IT UK
Address: 38 Grove Vale
Phone: +44 7951 878703
Business hours:
- Mon-Fri: 8 AM – 7 PM
- Sat: 10 AM – 5 PM
Solid Rock is a versatile company, offering support for both commercial and residential establishments. This makes them a one-stop shop, whether you need IT-related assistance for your home or your business.
Many people our researchers talked to expressed their appreciation for the team’s punctuality. They said that the team arrived on the agreed time—not too early, not too late.
In addition, the same set of people stated they work quickly. They can repair devices, install systems, and even upgrade hard drives in just a couple of hours.
For IT support services, they specialise in repairing a range of devices and installing WiFi in offices or homes. You can contact them if your laptop is malfunctioning or if you need help configuring a wireless network at your place.
However, most of their services are suitable for small businesses, so they have limited capabilities to help big establishments.
I highly recommend Solid Rock
“I recently had the pleasure of having Solid Rock visit my home to help set up my computer and screens. Their expertise and professionalism were evident from the moment they arrived. They quickly diagnosed the issues and provided efficient, clear solutions. The engineer also took the time to explain everything to me, ensuring that I felt comfortable with my new setup. Their friendly demeanor and willingness to answer all my questions made the experience stress-free and enjoyable. I highly recommend Solid Rock for any IT needs—top-notch service!”

I’m so happy that I used this company
“I am so happy that I used this company to fix my PC. The engineer booked me in for same day service which was so helpful because I had a fast approaching university deadline. The engineer came to my house and had my computer fixed in a few hours. There were a lot of things wrong with my PC and it was a challenging fix- he handled it with great skill and now it runs with zero problems. He was also very friendly and great to talk to. He went above and beyond by helping me after the service- my university asked for a repair note and he wrote me the document which was a massive help. I highly recommend Solid Rock and I will definitely be coming to them again if I need their help.”

3. Lucidica
Address: Unit 219, Brickfields, 37 Cremer St
Business hours:
- Mon-Fri: 8:30 AM – 6 PM
We were very impressed by Lucidica’s over 25 years of excellence. They’ve been providing top-quality services in various sectors since 1999. Their longevity and continued success are a strong testament that they’re one of the best.
Their flexible, tailored contract offering is one of their advantages over competitors. You can pick the support you need, and they’ll include it on the customised contract. This is great because some companies offer a one-size-fits-all contract, which isn’t practical.
When it comes to their services, they offer a decent number of IT support services. Some of them are on-site and remote IT support, system optimisation, and technology empowerment.
What we love most is that they offer IT support to charities and non-profit organisations. They help these social enterprises do more with less by providing discounted IT support packages.
The only problem is they’re not available on weekends. It’s just a minor problem, though, if you consider the kind of service you’ll get from them.
Greatly appreciated
“Lucidica have looked after our IT systems for a few years now and have even offered on-site support for our 24-hour hackathons, not an easy task! Their team is friendly, fast, and efficient. Simone is always available even for the most trivial of questions, and is always smiling when he enters our venue. Edoardo also helped to expedite an urgent website issue recently which was greatly appreciated. We look forward to continuing our partnership with them well into the future.”

A fantastic company doing fantastic work
“Our company loves working with Lucidica – they are always extremely responsive to our requests, always willing to try and figure things out, and make sure to follow up with us and ensure we’re happy with any resolution. They are a very friendly group of people and we never feel like anything is too much bother for them. Because of their responsiveness and excellent customer service, we are able to deliver for our clients too. A big thank you must go to Nikita too – he’s brilliant and we are thoroughly glad to have him support us! We would highly recommend Lucidica to anyone needing IT support – a fantastic company doing fantastic work.”

4. Sonar IT
Address: 124 City Rd
Phone: +44 20 3011 0805
Business hours:
- Mon-Fri: 7:45 AM – 6:30 PM
We find Sonar IT very suitable for people or businesses that have very little knowledge about the IT industry. They’re great communicators who discuss things without jargon.
Another good thing about them is their extensive IT optimisation services. For example, they can optimise the software you use in your organisation by techniques like code optimisation, algorithm upgrades, and building efficient data structures.
What’s even better is that they offer their services at a fixed, monthly rate. This is cost-effective, as you get unlimited support during a particular period without paying an additional fee when IT-related problems occur more than they usually do.
What we love most is the 30-day free trial offer. This allows you to test if they could be a great long-term partner.
That said, they have a relatively small team. This means a possible delay when they have multiple clients at the same time.
Sonar IT is the team to trust
“Seamless Microsoft 365 Migration – Highly Recommended! We partnered with Sonar IT for a full Microsoft 365 migration and setup, and the experience was outstanding. From initial planning through to execution, their team was professional, responsive, and incredibly knowledgeable. They ensured minimal downtime, handled data migration with precision, and set up our entire business with Teams, Outlook, and OneDrive in a way that instantly improved productivity. Post-migration support was equally impressive. If you’re looking for a smooth transition to Microsoft 365, Sonar IT is the team to trust.”
-Meekhil Patel, Google Review
I highly recommend them to any business
“SonarIT has been an excellent IT service provider for our business. Josh, Nick and the team are responsive, knowledgeable, and professional. They quickly resolved technical issues and provided valuable guidance on improving our systems. What helped me the most was their ability to explain M365 overly complex packages and their functionality concepts in simple terms. The pricing is fair for the quality of service received. I highly recommend SonarIT to any business looking for reliable IT support.”

5. Air IT
Address: 75 Farringdon Rd
Phone: +44 20 7101 0544
Business hours:
- Mon-Fri: 8 AM – 6 PM
We were amazed by the awards Air IT has received. This is a strong indication that they’re worth the people’s attention. Recently, they claimed the Channel Futures MSP 501 award and ranked number 2 in Cloudtango MSP Select UK 2025.
Living up to their reputation, most of the people our researchers spoke to stated that the team is very knowledgeable. They said that the team that visits on-site always finds ways to keep things simple when auditing their IT infrastructures.
For their IT support services, they can manage your cloud platform, provide an outsourced IT team as support for your in-house team, and more. They offer more than enough services to keep your business running smoothly.
Lastly, it’s worth mentioning that their processes are always aligned to the Information Technology Infrastructure Library (ITIL) framework. Following this framework benefits you as a client in a way that it streamlines every IT operation within your business.
However, they mainly work with large companies. This means you don’t have a chance to hire them even if you run a medium-sized enterprise.
Hands down five stars
“We have used their services for almost 4 years now and have to say that they are impeccable at the level of support they provide. They always go out of their way to solve the issues as soon as possible and also make an effort to explain in the simplest way possible as to what happened, instead of just saying ”Its all sorted”. They have a very structured hierarchy in terms of the levels of support required and everyone is very friendly & professional. They audit our infrastructure regularly and always find ways to keep everything simple, secure and most importantly cost effective. I would highly recommend, hands down five stars.”
