The UK company formation market includes several established players. TaxRoot, Companies Made Simple, 1st Formations, and Rapid Formations are among the most popular. Each offers different pricing tiers and additional services. The key differentiator is often what happens after formation: do you get ongoing accounting support, or is it purely a one-off filing service?

• Transparent pricing with no hidden fees
• Fast turnaround (same-day or next-day formation)
• Registered office address service if needed
• HMRC registration assistance for Corporation Tax, VAT, and PAYE
• Business bank account introductions
• Ongoing accounting packages available
• Good customer reviews and support
• Free company name check and availability search

Basic formation packages range from free (with paid add-ons) to around £50 for a standard package. Premium packages with registered office addresses, document templates, and additional services typically cost £50 to £200. TaxRoot offers company formation as part of its startup accounting packages, meaning formation is included when you sign up for ongoing accounting support. This provides significantly better value than standalone formation followed by a separate accountant.

TaxRoot differentiates itself by combining company formation with ongoing accounting support. When you form a company through TaxRoot, you get not just the formation but also HMRC registrations, accounting software setup, and a dedicated account manager from day one. This end-to-end approach eliminates the common problem of forming a company through one provider and then scrambling to find an accountant before your first filing deadlines.

Company formation is just the beginning. Within the first few months, you need to register for Corporation Tax, set up a business bank account, implement accounting software, and potentially register for VAT and PAYE. Many formation-only services leave you to handle all of this yourself. TaxRoot manages the entire process, ensuring nothing is missed and your company is fully set up and ready to trade.
