Excellent Service – Professional, Helpful and Reliable
We’ve had a very positive experience with Sleek managing the accounting for our limited company. The team are professional, helpful and responsive whenever we have questions.
They’ve made managing our company accounts, VAT returns and other accounting requirements much easier, allowing us to focus on growing our business.
We’re very pleased with the service and would happily recommend Sleek to other small business owners looking for reliable accounting support.

Terrible experience and NOT recommend…
Terrible experience and NOT recommended, process is slow and unreliable, takes them forever to reply and even longer to address it. My company have been paying for accounting services sine July and in November they haven't even started it yet.

Great assistance without a fuss.
I moved over from one accountant to Sleek and once I had my Zoom meeting with Abu and Tobie everything just fell into place. They assisted me with the transfer and took me through the process step by step with the new software. Once that was all done, Abu speedily completed my bookkeeping and VAT return, reminding me of the deadline for payment. Had he not done that I would have made a late payment as I had my dates mixed up. Thank you for that Abu.

Hi Andre,
Thank you for taking the time to share this. Switching accountants can feel like a big step, so we’re really glad your Zoom session with Abu and Toby made the move to Sleek and our software so smooth. It’s great to hear Abu got your bookkeeping and VAT return done quickly, and that his reminder saved you from a late payment. Abu and Toby are both valued members of our team, and I’ll make sure they see your kind words. If there’s anything we could do to earn that fifth star, we’d love to hear it at resolve[at]sleek.com.

I had an excellent experience working…
I had an excellent experience working with Renita Crasto from Sleek’s UK Incorporations team.
Renita has been extremely professional, responsive, and supportive throughout the process. She handled our requests promptly, kept me clearly informed at each stage, and always followed up to make sure everything was completed correctly.
What I particularly appreciated was her friendly communication and willingness to help whenever I had questions or needed clarification. Her support made the whole process smooth and straightforward.
I’m very satisfied with the service I received from Renita and Sleek, and I would definitely recommend them to anyone looking for reliable and professional corporate services in the UK.
Thank you, Renita, for your excellent support and service!

Not recommended, no clear communciations, no service
I have registered with them on September 27th and they haven't yet finalized my incorporation sadly.
1/ They assigned an account manager who is not responding to my message on Whatsapp - which means 0 onboarding
2/ The pace of incorporation is incredibly slow - Most other services do it within 1 week, for me, it's been 3 weeks already and spilling into the 4th week
3/ They apparantly missed onbaroding me into a critical part of the process, so they had to re-do some of the documents and asked me to find a "foreign director" - which added to the overall waiting time
Overall not recommended at all - no clarity, no service.

Hi Danial,
This is Johnathan from Sleek’s Customer Experience team. Thank you for your feedback, and I’m sorry your incorporation has taken so much longer than it should have. That isn’t the onboarding experience we want for anyone.
We’ve received the details of your new director, and our team is prioritising their verification so your incorporation can be completed as quickly as possible. If you have any other concerns, please reach me directly at resolve[at]sleek.com. Please allow us to put things right.

Good start but has become poor service
Started off great but as I've been with them over a year they seem to be not bothering to proactively do things anymore.
Disappointing. They used to be quite quick at responding and calling. Now I have to book an appointment in 2 weeks time. They'll contact me about something that's urgent.
Fairly unhappy now

Thank you for your response.
To clarify, your explanation indicates that as your client base has grown, staffing has not kept pace with demand. The result is that despite paying the exact same monthly subscription fee, I now have significantly less access to my designated accountant—moving from prompt, direct communication to a required two-week wait for a scheduled call.
From a client perspective, paying the same price for a reduced level of service simply means less value for money.

Hi Matthew,
Thank you for your feedback. We appreciate your loyalty over the past year, and we are truly sorry to hear that your recent experience has not met the high standard of service you came to expect from us.
As our client base grows, we have introduced scheduled appointments to ensure our team has dedicated time to thoroughly review each client's file before speaking, rather than rushing through calls. However, we completely understand your frustration when urgent matters arise and a standard booking window feels too distant.
Urgent matters should always be handled promptly, and we regret if communication fell short in this instance.
Thank you again for bringing this to our attention—your long-term relationship with us is important, and we hope to regain your confidence.
