Construction Accountants for Growing Builders, Contractors & Construction Firms
At Julian Hobbs & Co., we work with builders, contractors, property developers and growing construction firms across Hertfordshire and Welwyn, not only gaining control over their financial and regulatory aspects, such as CIS obligations and cash flow – but also with managerial & project specific accounting — promoting growth that withstands the test of time and financial pressures.
Gain Financial Clarity Across Projects
Your portfolio may include projects reporting losses and financial strains. With project-level reporting, forecasting and WIP tracking, you gain an upper hand - regaining control and guaranteeing healthier outcomes.
Stay CIS & VAT Compliant
Contractors and subcontractors alike need an in-depth understanding of CIS reporting and reverse VAT rules if they are to avoid HMRC fines and penalties. We help construction businesses with exactly that, and more.
Strategic Finance Support for Growth
Growth comes with a demand for precise financial and management reporting - no longer optional. Outsourcing your finance function enables smarter, strategic decision-making and control at a fraction of the cost.
Construction Accountants for Businesses Across Hertfordshire & North London
The construction sector in the UK is the most unstable market, marked by fluctuating costs, rising subcontractor mismanagement and payment delays. Whether you’re operating in Welwyn, Hertford or other North London corridors, maintaining financial clarity while adhering to CIS, VAT, HMRC compliance, and workplace safety and employment regulations is nearly impossible without specialist support.
Your accounts deserve a partner that does all this— someone who can effortlessly work alongside you – navigating behind-the-scenes complexities and strengthening your portfolio profitability, year round.
Construction Businesses We Support
Builders & Construction Companies
We work with builders and construction companies, helping them with management accounts, customised CIS bookkeeping, and forecasting - providing a full-fledged solution that grows with them.

Property Developers
Developers are expected to have detailed project accounting and forecasting due to their capital-intensive nature. Our chartered accountants help with this, regaining control from start to finish.
Trade Businesses
Trade businesses like electricians and plumbers, require clear and accurate accounts at all times, with stronger cash flow control. Our team can help with this - ensuring structure and consistency.

Growing construction SMEs require monthly management and financial reporting that grows with their business stage. Outsourcing this helps streamline processes, driving data-backed investment decisions.
Multi-Project Construction Firms

Frequently Asked
What does a construction accountant do?
A construction accountant does the accounting and financial work that’s specifically for the construction industry. This includes things like CIS accounting, management accounts, bookkeeping, VAT returns, forecasting, project profitability reporting and tax planning.
Can you help with CIS returns?
Yes we can help contractors and subcontractors with their CIS returns, verifying subcontractors reporting deductions and making sure they are following the rules. We make sure the submissions are accurate and on time and records are organised all year round.
What is reverse VAT in construction?
The domestic reverse charge VAT system changes how VAT works between contractors and subcontractors in the construction industry. Now subcontractors do not charge VAT on services and instead the contractor handles the VAT through their own VAT return.
Because the rules can be complicated it is important to get invoicing and reporting right. Construction accountants help reduce errors and keep VAT compliance on track.
What expenses can construction businesses claim?
Construction businesses can claim a variety of expenses depending on how they work, including:-Materials and supplies
- Labour and subcontractor costs
- Vehicle and travel expenses
- Tools and equipment
- Protective clothing
- Office expenses
- Software subscriptions
- Insurance
- Training and professional fees
How do management accounts help builders?
Management accounts give builders and construction businesses financial updates throughout the year rather than just at the end of the year.
For businesses with multiple projects this level of reporting really improves financial control and decision-making.
What accounting software is best for construction companies?
Many construction businesses use cloud platforms like Xero and QuickBooks because they give time, financial visibility and make bookkeeping easier. The right choice however, depends on the size and complexity of the business. Julian Hobbs & Co. can help with this, ensuring the chosen software solution is performing what’s required, and more.
Can you provide finance department support?
Yes. We provide outsourced finance support for growing construction businesses that need stronger financial control without hiring a full in-house team.
