Accountants for Engineers

If you’re an engineer working through a limited company or contracting on projects, your accounting needs to be as reliable as the work you deliver.

IR35, VAT, dividends and allowable expenses all require careful handling alongside demanding project deadlines. Small errors can lead to unnecessary tax, penalties or avoidable stress.

As experienced engineering accountants, Mollan & Co supports engineers across the UK with clear, practical advice that keeps things compliant and under control.

Our Accounting Services for Engineers

We provide core accounting and tax services to help engineers run their businesses confidently and efficiently. Our services include:

Accounts & Company Tax: Preparation of annual accounts and submission of your company tax return, ensuring everything is filed correctly and on time.
Bookkeeping & VAT: Cloud bookkeeping and VAT return submissions, including guidance on VAT registration and scheme selection.
Tax Planning & Personal Returns: Ongoing tax planning to structure your income efficiently, alongside support with Self Assessment where required.
Payroll & Workplace Pensions: Directors’ payroll and support for engineering consultancies employing staff, including PAYE and pension compliance.

As your business grows, we can also support with management accounts, new company registrations and broader business advice.

Engineering Contractor Accountants

Many engineers move into contracting for flexibility and higher earning potential. But this means taking responsibility for your own company structure, tax position and reporting.

As engineering contractor accountants, we help you put the right foundations in place and ensure your setup continues to work as contracts and income change.

You stay focused on delivering projects. We make sure the numbers are handled properly.

IR35 Support for Engineering Contractors

IR35 remains one of the most important issues affecting accountants for engineering contractors today.

Both contract wording and working practices determine your status. Getting it wrong can significantly affect how your income is taxed.

We review contracts, explain your position clearly and help you plan appropriately if a contract falls inside the rules. Addressing IR35 early avoids uncertainty later.

Switching to Mollan & Co

If your current accountant feels reactive or difficult to reach, changing firms may be simpler than you expect.

We manage the transition professionally, liaise with your existing accountant and ensure records transfer smoothly. Your reporting and deadlines stay on track throughout.
