Customer service is top-notch! We had a small issue with our network connectivity and Sirus responded immediately. Their support team was polite, professional, and had the problem sorted within the same day. Really impressed with their efficiency.

One Star – Avoid Sirus Telecom at All Costs

My experience with Sirus Telecom has been nothing short of frustrating and disappointing. From the beginning, I was pressured by a pushy sales rep into signing a long-term contract with the promise of "locked-in low rates." What they don't tell you is that those rates skyrocket after a few months, and you're stuck in a contract that’s nearly impossible to get out of without paying massive early termination fees.

The charges keep increasing with no clear explanation. Every bill seems to come with new fees and surcharges that weren’t part of the original agreement. Customer service is nearly impossible to reach, and when you do get through, they’re more interested in upselling or extending your contract than resolving the issue.

Sirus Telecom locks you in with multi-year commitments while providing a service that doesn't reflect the cost. I regret ever signing up. If you're considering Sirus, do yourself a favor and look elsewhere. The long contracts, hidden fees, and never-ending bills simply aren’t worth it.

I really cannot stress enough about NOT using this company, you may see some reviews that are OK but I am sure in 6 months they will be eating their words.

The costs that your sold are NOT the costs you will get, the sales guy Rob, at even a hint of a problem, becomes tone deaf and can't seem to use his hands to answer the phone...

You are sold 'robust phones' yet when one breaks you are asked to tie into a further 7 year contract for them to renew it, so currently we only have one handset working as I would rather do that than sign for one more second with these people

We picked these sharks as they were a local company to us and in my craziness I thought I was doing the right thing.... Clearly not!

The telephone costs now are ridiculous for 1 line into a small business, as an example, £139 to them and £80 odd quid to GRENKE, this is BY FAR way way over anything BT would charge you!!! Then you get a yearly fee also just as a brucie bonus...

I have spoken to people there who have promised to look into things but never do I get a response or a call back...

Seriously shocking and if you sign with them be sure to come back and re-read what I have warned you of!!!

Never in 30years of business have I come across a company so horrendous as Sirus. Be very wary of signing anything with this company.

Do not sign anything this company gives you. I wish I had read some of the reviews before I allowed them to come in and see me.
They do not disclose the full price and make out they are offering you a good deal, which is twice as much as I was paying. The sales man led me to believe the full price he was quoting included everything. However, it did not even include the broadband and there seem to be many other charges.
Then he pulled out finance documents which needed signing, not pointing out any of the extra costs or that this would cost thousands of pounds more than if we just bought the phones. This was not part of the cost he said would be the monthly cost. On top of that they extend the contract which is makes you wave your rights as a small business.
All in all how they treat small businesses and customers deceitful. They do not talk to you reasonably and I would avoid at all costs.
I have been so distressed about how they have coned our company it has affected my sleep and ability to function.
Please do not sign anything they give you or let them come and see you.

As a Sirus customer for over 5 years now I can say it’s always been a pleasure.

Nothing has been too much of a problem, from sales to installation to customer services.

I couldn’t recommend anyone more than Sirus, on my second upgrade now and it has been just as hassle-free as the first.

I rarely leave negative reviews, but my experience with Sirus Telecoms has been frustrating enough that I feel compelled to warn others.

Most concerning is their billing practice. Charges for services I never requested or agreed to were regularly added to my bill. When I contacted customer service, I received vague, unhelpful responses and no real resolution. It feels like they’re hoping customers won’t notice or will just give up trying to dispute the charges. They refuse to remove the added (not requested) charges without paying termination costs.

To make matters worse, the salesperson who signed me up outright lied about the plan details. What was promised during the sign-up process—pricing, data allowances, and contract terms—was completely different from what I actually received. When I tried to raise the issue, I was given the runaround.

Sirus Telecoms appears to lack transparency, accountability, and even basic respect for their customers. I’ve since switched providers, and the contrast in service and honesty is stark. My bill is now 80% lower now from when I was with Sirus for the same number of phones and free calls.

I strongly advise others to be cautious and read every detail of your agreement—if you still choose to go with them. Look at Google reviews as well!

If you are considering using or signing into a contract with this company please don't.
They are the biggest scammers going.
I work for a company that was conned by these guys a few years ago and our company is still paying the price for it.

Would advise everyone to avoid this company, they have a very misleading sales approach and additional extras charges which are perceived to be included, now being charged twice as much as previous operator.
Very frustrating!!!!!!

I have had an incredibly frustrating experience with Sirus Telecom. Initially, I was misled into signing a long-term contract under unclear terms. Recently, I was pressured into signing a new agreement, only to find out it involved a separate leasing company (Grenke), which was not made clear at the time.

When I raised concerns and tried to cancel the agreements, I was met with vague responses, no clear resolution, and even threats of additional charges for "liquidated damages." Customer service has been dismissive and unhelpful.

To make matters worse, an email address provided for their customer services was non-functional, adding to my frustration. Despite my efforts to resolve this amicably, I’ve been left feeling ignored and unsupported.

I strongly urge anyone considering Sirus Telecom to think twice and carefully scrutinize any agreement they are asked to sign. Their lack of transparency and poor communication have been extremely disappointing.

Sirus have to be one of the best providers in the UK we have worked with them now for over five years and I cant fault them ! the whole team is excellent from customer service to technical

great service, would recommend.

Extra charges soon mount up

They charged me extra for calling UK mobile networks. It has been going on for the best part of a year. Queried it they said they made a mistake and credited me a very small amount back, but they still charge extra every month for calling UK mobile networks. It's not right.

Cannot wait for my contract with them to finish.

Thank you for providing us a service over the past 5 years

I have been with Sirus six years and they have provided a first class and uniterupted telephone service for us.

We have been with Sirus Telecom a number of years, and their dealings with us have always been clear, straightforward and professional. Any problem with our system has always been sorted out quickly and easily enabling us to keep in contact with our clients which is so important to us.

We have been with Sirus since 2019, we have found their care to be 10/10. The communication and help has been very good.

My business has been with Sirus for 6 years and I would highly recommend them very professional and very efficient

Very happy with the service, great communication and timely service of the alarms and CCTV.
