What Clients Say

Experiences Shared by UK & Overseas Clients

★★★★★
I emailed Sirius at 9:15 am and had a call from a specialist by 10:45 am the same morning. Within two days my VAT registration was submitted and I had my VAT number within the week. That's the kind of responsiveness I expected but rarely get from professional services firms.
E-commerce Owner — Harrow, UK
★★★★★
Based in Mumbai, I needed a UK company for my tech consulting work and had no idea where to start. Sirius Global Solutions handled everything remotely — registered office, ECCTA director verification, Corporation Tax registration. Never had to travel to London. Completely professional from first WhatsApp to receiving my Certificate of Incorporation.
Technology Consultant — Mumbai, India
★★★★★
I came to Sirius after receiving an HMRC compliance check notice — I was genuinely worried. The team explained my options clearly, managed all the correspondence, and the matter was resolved without any penalty. Their Stanmore office was easy to reach by tube. I now use them for all my accounting and payroll as well.

Frequently Asked Questions

Your Questions About Contacting Us — Answered

Everything you need to know before reaching out — from response times to consultation fees, languages, and what to prepare for your first call.

For enquiries submitted via the website form or by email, we respond within 2 business hours during office hours (Mon–Fri 09:00–18:00 GMT, Sat 10:00–14:00 GMT). Urgent HMRC compliance deadlines or same-day company registration needs should be handled by calling us directly on +44 74 8275 5633. Enquiries submitted outside office hours receive a response by 10:00 the next working day morning.
Absolutely. A large proportion of our clients are overseas-based — in India, the UAE, Hong Kong, and beyond — who manage their entire engagement with us remotely via phone, video call, WhatsApp, and email. All company registration, HMRC compliance, VAT registration, and accounting services are delivered digitally. Where physical documents are required (such as apostilled UK company documents), we co-ordinate their preparation and dispatch on your behalf.
You do not need to prepare formal documents for the first call — we identify what is needed once we understand your situation. It helps to have a brief description of your business activity, any Companies House or HMRC reference numbers if you are already registered, an indication of annual turnover or projected revenue, and details of any specific deadlines or correspondence you are facing. For international incorporation enquiries, knowing your target country and business sector is sufficient to begin the conversation.
We offer a free 30-minute initial consultation — by phone, video call, or in person at our Stanmore office — for all new enquiries. This allows us to understand your requirements and provide an indicative scope and fixed-fee quote with no obligation. For complex matters requiring in-depth document review before advice can be given (such as an HMRC compliance notice or a multi-jurisdiction corporate structure), a brief paid review session may be recommended — quoted transparently in advance and credited against any subsequent engagement.
Yes. Our team advises and corresponds in English, Hindi, and Gujarati — particularly useful for British Indian business owners and entrepreneurs from South Asia who prefer to discuss complex regulatory matters in their first language. For other languages, we work with professional interpreter partners. All formal written advice, engagement letters, and compliance documents are issued in English, as required by HMRC, Companies House, and all regulatory filings.
We recommend booking in advance to ensure the right specialist is available for your service area. Our Stanmore office at Devonshire House, 582 Honeypot Lane, HA7 1JS is accessible by tube (Stanmore on the Jubilee Line, approx. 10 minutes' walk) and has parking nearby. Walk-ins are welcome during office hours for straightforward queries, but appointment booking guarantees uninterrupted time with a dedicated adviser.
You do not need to pre-select a service — that is our job. When you contact us, simply describe your situation and goal. Our intake process asks structured questions to route your enquiry to the right specialist. Starting a UK business for the first time is typically company formation plus Corporation Tax and VAT registration. Receiving an HMRC letter means compliance assistance. Expanding into India, Hong Kong, UAE, or Australia means international incorporation. Many clients need multiple services simultaneously, and we are well positioned to co-ordinate across all of them from a single point of contact.
Yes. Our Stanmore address — Devonshire House, 582 Honeypot Lane, HA7 1JS — can serve as your UK company's registered office for Companies House purposes and as a director service address. The service includes scanning and forwarding of all statutory and legal correspondence, prompt notification of HMRC letters or Companies House deadlines, and secure digital storage of your statutory books. Available to both UK-resident and non-UK-resident directors. This service is included in our UK Complete company registration package and available as a standalone annual subscription.
