MB Corporate Services owns and operates the platform and provides registered office, business address, digital mailroom and portal services. Accountants4All is the professional accountancy practice that delivers AML/KYC onboarding, company formation, HMRC registrations, accounting, VAT, payroll and all statutory compliance work. Both operate under their respective professional and regulatory frameworks.
Yes. The platform is specifically designed to handle UK and non-UK resident directors, shareholders and PSCs. Non-UK clients follow an enhanced onboarding pathway that includes source of funds and wealth checks, jurisdiction risk review and, where required, enhanced due diligence. All checks are completed by Accountants4All before any services commence.
No. Company formation, registered office activation and all professional accountancy work are subject to successful completion of Accountants4All's AML/KYC onboarding and client acceptance process. This is a regulatory requirement and cannot be bypassed regardless of the urgency of the client's situation.
No. Banking support is limited to application-pack preparation and introductions where available. The decision to open any account rests entirely with the bank. We do not guarantee approval. Clients should be aware that UK banks apply their own due diligence processes, which are entirely separate from the AML/KYC performed by Accountants4All.
The client portal is the central hub for your relationship with MB and Accountants4All. Through it you can view scanned mail, upload financial records, approve accounts and filings, track compliance deadlines and send secure messages. The portal has separate sections for MB address and mailroom services and A4ALL compliance work, presented as one coherent experience.
The platform supports new UK limited companies, overseas-owned UK companies, existing UK limited companies requiring address or compliance support, sole traders, partnerships and LLPs. Charities, CICs and other special entities are accepted subject to enhanced review and specialist approval from Accountants4All.
