Construction has its own rules, its own deadlines, and its own ways of catching you out.
Construction accounting isn’t like other trades
Verifying subcontractors. Filing monthly CIS returns. Tracking deductions. Reclaiming overpaid tax. Managing retention and the Domestic Reverse Charge on VAT. The admin in construction is relentless, and the penalties for getting it wrong are immediate.
Most general accountants treat construction like any other business. It isn’t. The deduction rules, the cash timing, and the level of HMRC scrutiny all work differently, and they punish anyone who treats them casually.

Common Questions
What’s the difference between this and your CIS service?
CIS is the returns and compliance. Contractor Support is the wider day-to-day service around it — bookkeeping, tax, accounts, and advice, all built for the way construction works.
I’m a subcontractor — can you reclaim my CIS deductions?
Yes. We track the tax deducted from your payments and reclaim any overpayment through your self assessment or company return.
Do you handle the Domestic Reverse Charge?
Yes. We make sure VAT is applied correctly on construction services, so neither you nor your customer gets it wrong.
Can you do my monthly CIS returns and my accounts?
Yes — that’s the point of this service. One accountant covers the lot, rather than splitting it across different people.
I’m always chasing retention and stage payments. Can you help?
Yes. We set your bookkeeping up around how construction actually gets paid, so you can see what’s owed and when.
