We deliver construction bookkeeping, CIS accounting services, construction domestic reverse charge VAT handling, payroll, and year-end accounts so your team focuses on review and client relationships, not data entry. Twelve years of UK construction accounting experience sits behind every file we return.

Why it works · What you get
Built for Construction Practices. Not Adapted - Purpose-Built.
01 - CIS, DRC and CT600 - sorted.
The CIS paperwork nobody wants to do.
Subcontractor verifications, monthly CIS300 submissions, CIS bookkeeping, and suffered deductions reconciled to the penny. The work that quietly eats up an accountant's week - we take it off your desk and hand it back review-ready.
02 - Retentions and construction industry reverse charge - daily work.
We've untangled enough retention schedules to know the patterns.
Construction domestic reverse charge VAT on mixed supplies, applications for payment versus valuations, retention release timing, project margin shifts on long contracts - construction throws curveballs other sectors don't. We've seen most of them already.
03 - When the tender deadline is Friday.
Five working days. Faster when a contractor needs CT600 figures for a tender.
Construction accounting UK work is deadline-driven, and standard delivery is 5 working days from source data to working papers. When something is urgent - a tender, a bank covenant check, an HMRC enquiry - we move faster. You'll never hear that we're waiting on the next slot.

Real questions from UK accountancy practices answered honestly.
If you're considering construction accounting outsourcing UK support for your construction clients, you probably have a few questions. Here are the ones we get asked most, with straight answers.
Still have questions? Get in touchYes - construction accounting is one of our core specialisms. We work with UK accountancy practices that have anywhere from a handful of construction clients to entire portfolios built around contractors, subcontractors, and developers. Whether your clients are sole traders, limited companies, or multi-site developers, we know the work and we're set up to handle it.
Yes. We deliver the full recurring workflow - construction bookkeeping, CIS bookkeeping, bank reconciliations, VAT services (including the construction industry reverse charge), management accounts, payroll, and year-end preparation. You can bring us in for one workflow or hand over the whole lot - it's entirely up to you and what your practice needs.
Yes - DRC VAT is something we deal with regularly. We understand which supplies fall within the reverse charge rules, how to apply them correctly on invoices and returns, and how to handle mixed supplies where some elements are standard-rated and others are not. If your construction clients have been getting this wrong, we can help clean it up and make sure it's right going forward.
We track retentions, applications for payment, and valuations through the bookkeeping workflow so revenue recognition stays accurate and the reviewer sees project-level margin movement clearly. Management accounts can be tailored to show project margin and contract performance.
Moving construction accounting UK work across to us is straightforward and designed not to disrupt your practice. We start with a short call to understand your client portfolio and how you currently work. From there, we agree on workflows, access, and turnaround expectations - usually within a week. Most practices are fully up and running with us within two weeks of that first conversation. We work around your systems, not the other way around.
Yes. We prepare the CIS tax return and the CIS self assessment tax return for subcontractor clients, reconciling deductions suffered against the payment and deduction statements from each contractor before anything is filed. Where too much has been deducted, the repayment is claimed through the return rather than left sitting on the account. Limited company subcontractors are handled differently - deductions suffered are reported through the EPS and set against the PAYE liability, not the self assessment return - and we keep the two routes separate so nothing is claimed twice.
No, although the two are linked and the terms get used interchangeably. CIS governs the deduction a contractor takes from a subcontractor's labour and reports on the monthly CIS300. The construction industry reverse charge VAT rules govern who accounts for the VAT on that same supply. What connects them is scope: the domestic reverse charge applies to supplies that fall to be reported under CIS, between VAT-registered businesses, where the customer is not an end user. Get the CIS status wrong and the VAT treatment usually goes wrong with it, which is why we look at both together rather than in isolation.
Pricing for construction accounting UK support is per client, per workflow, based on transaction volume, how many subcontractors sit on the CIS scheme, and whether reverse charge supplies are in the mix. There is no retainer, no minimum volume, and no separate charge for the senior review. Send us one real client and we will price it properly rather than quote a headline rate that changes at month three.
