Office Address
28 Grangewick Road , Grays , Essex , RM16 2DWWe prepare and file your limited company’s statutory accounts, Corporation Tax return (CT600) and Companies House submission for a fixed fee agreed upfront.
Filing your statutory company accounts shouldn’t slow your business down. Based in Grays, our certified accountants prepare year-end accounts, corporation tax returns and Companies House filings for limited companies and directors across Essex, Thurrock and East London, whether you run a tech firm in Romford or a service business in Barking. Every set of accounts is prepared to UK GAAP standards and checked before it is filed with Companies House and HMRC.
Never billed by the hour.
We manage your regulatory compliance from start to finish, offering transparent, fixed-fee solutions tailored to your business.
We organise your financial records and prepare professional Profit & Loss statements and Balance Sheets to UK GAAP standards.
Our senior accountants review your transactions, claim the deductions you’re legitimately entitled to, calculate your liability and submit your CT600 directly to HMRC.
Avoid late penalties. We prepare, double-check and file your company accounts with the registrar well ahead of your statutory deadline.
HMRC and Companies House enforce strict timelines that trigger automatic fines if missed. Our office tracks these milestones so you can focus on running your business.

“Excellent service. The company managed my business accounts effectively with no mistakes and always kept me posted.”
“Very good, in time and prompt service. Very happy with the work and advice.”
Yes. Whether your numbers are on paper, spreadsheets, or incomplete digital files, we carefully reconcile your books to ensure complete HMRC compliance when preparing your company accounts.
Switching is entirely hassle-free. We handle all communication with your previous agency, safely transfer your financial records, and notify HMRC on your behalf.
If you have missed a deadline, we urgently prioritise your late-filing case to stop escalating fines, before reviewing any legal grounds for an official penalty appeal.
Ideally, within three months of incorporation. This allows us to establish a robust accounting structure, manage your bookkeeping habits, and implement tax-saving strategies from day one.
