Sirus Ltd Avis 

Our overall experience with Sirus has been great. Jordan and Dan set up the phone systems efficiently and answered all our questions with no problems.
Our sales contact, Ed, has also been great to work with.

Very helpful, prompt and informative salesman. Customer support also very helpful often going above and beyond their obligations to me.

We joined Sirrus in December 2025. Ed, the sales manager, was a decent bloke who explained how everything would work, and initially it all sounded great, including some potential cost savings compared to our previous system. Unfortunately, that’s where the positives largely ended.

The installation itself went smoothly, but the engineer left before even a temporary divert was working properly. The system seemed fine for the first week or so, but then the call quality dropped dramatically. We now really struggle to understand calls on the supplied handsets.

We were told this is due to the broadband line rather than the phone system, as the broadband is supplied by another provider. However, we were under the impression that Sirrus would be handling the switch of both lines and broadband together, which turned out not to be the case. We have since been offered broadband through them at additional cost, which we feel should have been made clear and included as part of the original discussions.

We reported the call quality issues in early January 2026 and, as of the end of February 2026, we are still waiting for a proper resolution.

Based on our experience, I would recommend others carefully consider their options before committing to this provider.

They provide us an excellent service. I have been dealing with Jordan Cull. Very helpful and quick to respond to queries.
5 Star.

Like a lot of businesses, leaving a positive review for a telecom company is not always easy! We spent a lot of time with John who explained what we needed, what we could have and let us decide the route we wanted. No hard sell and a plan that was very suitable for us.
Would genuinely recommend.

John spent a lot of time with us making sure the plan was right for our business needs. The process was easy and I would recommend Sirus.

I asked for help from Sirus with Spy calls and within 1/2 hour it was all sorted.

Sirus have provided and maintained our security cameras for the past 4 years. Excellent service from the off and have never had a single issue. Knowledgeable sales staff and professional installers. Would highly recommend!

Was expecting the usual faff with installation etc but it was surprisingly painless. Up and running straightaway. Would recommend to anyone.

Avoid this company. They are for you if you can afford extortionate rates applied 2 years into your contract unless you sign up for even longer than the 7 years you have been cajoled into. READ THE SMALL PRINT! Do not fall into the same trap as many other companies. They will not reduce the number of handsets, even if you have downsized your team. They are hard selling on another level

We've worked with Sirus for many years now and always had great service and quick response to any faults that may have cropped up. Jordan always goes above and beyond to make sure that installations go smoothly.

Great service from Sirus Telecoms - thank you. It is nice to have a friendly voice at the end of the phone - when we have had queries about how to use the new system, it has been dealt with quickly and efficiently. Pricing is straight forward and we know what we are getting. Engineers have been friendly and professional on their visits. Happy to recommend them.

Moved over to Sirus several years ago for our office phone system, and from day one any help we needed was there straight away, i then had a problem with our Mobile network supplier (they got bought out by ONECOM), very unhelpful, reached out to John at Sirus and in 2 days had 20 new sim cards on there network and saved money. Great business to work with.

This was a very unpleasant experience
This was a very unpleasant experience. Didn't get to see the contract for weeks, the email was being sent incorrectly, then found out I had an expensive 7 year lease I cant get out of. Over priced and oversold 3 phones, even though they only set up two lines. Now my small business is suffering as the costs go up.
They came in for a review and I explained it was too much money, they offered me an additional phone and to start my 7 year lease all over again. It’s a scam. They use high pressure techniques to try and get you to sign quickly and on the spot before you can process the informationand check it carefully. The monthly cost I was originally shown was not the actual figure. And the 7 year lease was never explained! Please avoid at all costs !!

I had a contact with Sirus and after 3 years a member of their sales team visited and said he could cut my monthly charge, saving my company £1,200 over the remaining contract. I asked and he confirmed that there was no new contract - a blatant lie!
Now i have a new 7 year contact and my bill has risen to over an extra £50 per month.
Made a formal complaint and told it would take 8 weeks to determine. Next stop Ofcom!
Think twice before you out pen to paper. For me the journey hasn't been a pleasurable one and look forward to seeing the back of this company.

Offered a review of services in October 2024 to reduce costs for us - sold the usual sales speal with emails guaranteeing huge savings and then when we signed up to a new contract was hit with a number of 'extras' which took our monthly cost back up to same original cost - complete lack of accountability and poor customer service - would definitely not recommend

They are liars. Don’t believe paid reviews

Sirus have always been an excellent telecoms partner to JD Yachts Limited and have gone over and beyond to provide the very best service even out of hours ! Would thoroughly recommend them to any business

Sirus are absolute charlatans. Having been with them for 4 years and been voicing concerns about broadband speeds and IPT service quality they moved me into a ridiculously expensive 5 year contract with seperate phone leasing agreement with Grenke (also for 5 years). The combined package ended up costing more than twice what I was paying previously (despite promising I would pay less!). All in my bills rose to £250 per month which for a 1 man band was far too much. Despite trying to trim the service back and lose the IPT service they've refused and keep waiving the contract that they gained signatures off me on under false pretences. Horrible people, horrible service. Do not use them ever!

READ PAST THE FAKE REVIEWS – CLASSIC 4COM-STYLE STITCH UP!
Signed a deal thinking I was getting a good package – turns out I’m locked into a 7-year contract and the phones? I’ll never even own them!
Paid for 5 phones over the contract length, could’ve bought a range rover for the same price 🤯
Clearly full of fake 5-star reviews – don’t fall for it. Avoid this cowboy outfit at all costs
