Why construction needs a specialist accountant

Construction tax is its own world. Generalist firms get it wrong.

Construction has its own deduction scheme, its own VAT rules, its own gross-status regime, and its own cash-flow timing. The four problems below show up in nearly every onboarding call from a builder, plumber, electrician, scaffolder or groundworker who's been with a generalist firm.

Symptom #1

"My old accountant didn't claim half my expenses."

Tools, vehicle costs, mileage at 45p, PPE, training, public liability, work clothing, phone, materials, sometimes home office - most generalist firms tick the obvious boxes and miss £500-£2,000 of allowable expenses on a typical sub-trade return. We prompt for everything claimable line by line.

Symptom #2

"I waited 4 months for my CIS refund."

HMRC pays CIS refunds in days when the return is correct and complete. Slow refunds usually mean records gaps, missing contractor verifications, or the accountant simply not chasing. We file complete returns from May to October, pull deductions direct from HMRC where contractor slips are missing, and chase the refund into your account.

Symptom #3

"I can't get a mortgage because my accountant won't issue an SA302."

Every UK lender accepts SA302 + Tax Year Overview as proof of self-employed income. Generalist firms often don't know how to produce them or charge £40-£80 each. We produce both, certify them on chartered headed paper and email them within 24 hours - included in the £350 annual fee.

Symptom #4

"Nobody told me about Domestic Reverse Charge VAT."

Since March 2021, VAT-registered subcontractors providing services to other VAT-registered contractors do not charge VAT on their invoices. Plenty of trades still invoice VAT incorrectly and have to refund it later. We review your invoice templates, set up DRC handling in your software and adjust your VAT return treatment.

Real construction outcomes

What our construction clients actually got back. Real numbers.

Three recent examples from sole trader subbies, growing contractors and multi-trade businesses across London. Names changed, numbers real.

Stage 1 - Sole trader subbie

£4,200 CIS refund the previous accountant missed

Marcus had been with a £40/month online firm for three years. They filed his SA but never reconciled CIS deductions properly and missed several months of contractor verifications. We pulled the data direct from HMRC, identified £4,200 of unrecovered CIS, filed a corrected claim and chased the refund into his account in 23 days. We also issued his SA302 for a buy-to-let mortgage application - same day.

Year-1 net benefit
+£12,400
Stage 2 - Sole trader → Ltd Co

Saved £6,800/year by incorporating at the right moment

Sarah was running £75K of net profit through self-assessment, paying full income tax and Class 4 NIC. We modelled the limited company position in a free 15-minute call - optimal salary plus dividends saved £6,800/year on the same profit level. We handled the formation (£400 one-off), set up payroll, registered for CIS as a contractor, and onboarded her onto Tier 2 accounts at £2,200/year. Net saving year one: £4,200 after fees.

Net annual saving
+£4,200/yr
Stage 3 - Contractor with team

GPS application unlocked £140K of tied-up cash flow

Daniel ran a £1.4M turnover groundworks business with 12 subbies on the books. Without Gross Payment Status, his contractors were deducting 20% from every invoice - about £140K tied up across the year, repaid only via annual reconciliation. We reviewed his eligibility (clean compliance, turnover well above threshold), submitted the application, and HMRC granted GPS within 6 weeks. Cash flow uplift was immediate. We also moved him from a £2,000/month firm to our full bundled service at a saving of £700/month.

Cash flow uplift + fee saving

Construction accounting questions answered

Frequently asked questions.

If your question isn't here, message us on WhatsApp or book a free 15-minute call.

Do I need to register for CIS as a sole trader subcontractor?+
Yes - anyone working in construction as a subcontractor must register with HMRC under the Construction Industry Scheme. Without registration, contractors must deduct 30% from your invoices instead of 20%. Registration is free and takes about a week. We handle it for you as part of onboarding at no separate charge for new clients.
How much does a construction accountant cost in London?+
Sole trader CIS subcontractors pay a fixed £350/year for the full self-assessment service including refund chasing and free SA302 for mortgages. Limited company contractors with monthly CIS returns typically pay £1,200/year for accounts and corporation tax plus £95/month for monthly CIS returns. Larger multi-trade businesses with payroll, VAT and bookkeeping typically settle between £400 and £750/month for the full service. All prices exclude VAT and quotes are issued in writing within 24 hours.
What is Gross Payment Status and should I apply?+
Gross Payment Status (GPS) means contractors pay you in full with no 20% CIS deduction at source. You instead pay your tax annually through self-assessment or corporation tax. To qualify HMRC checks your turnover (must be above £30K for sole traders or £30K per director for limited companies), your tax compliance history (no late filings or unpaid liabilities in the last 12 months) and your business activity. GPS dramatically improves cash flow and is usually worth pursuing once your turnover and compliance are clean. Our fee for handling the application is £400 one-off.
What is Domestic Reverse Charge (DRC) VAT for construction?+
Since March 2021, VAT-registered subcontractors providing services to other VAT-registered contractors do not charge VAT on their invoices. Instead the contractor accounts for the VAT under the reverse charge mechanism. Most subcontractors who became VAT registered after the change have never invoiced VAT to construction contractors. We review your invoice templates, set up DRC handling in your accounting software, and adjust the VAT return treatment correctly. £250 one-off setup.
When should I switch from sole trader to limited company in construction?+
For most construction trades the tipping point is around £40,000 to £50,000 of net profit (after expenses but before tax). Below that figure the tax saving from incorporating is usually too small to justify the extra admin and £1,200/year accountancy cost. Above that figure you typically save several thousand pounds per year by drawing optimal salary plus dividends instead of paying full income tax and Class 4 National Insurance on self-employment profits. We model your specific numbers in a free 15-minute call before you commit to anything.
Do you handle CIS investigations and HMRC enquiries?+
Yes. CIS investigation support starts from £695 per case and covers records review, response drafting and HMRC representation. Most CIS enquiries focus on subcontractor verification status, deduction calculations, and Gross Payment Status compliance reviews. Tax Investigation Insurance is £15/month and covers up to £100,000 of professional fees if HMRC opens an enquiry.
What's the difference between this and your CIS service page?+
The dedicated CIS Construction Specialists page covers our specific subcontractor self-assessment service in detail - fixed £350/year, what's included, the process, the SA302 for mortgages. This industry page covers the full construction journey from sole trader to multi-trade limited company including formations, monthly CIS for contractors, GPS applications, DRC VAT, payroll for site teams, and ongoing accounts. Use the CIS service page if you are a sole trader subbie wanting one annual filing. Use this page if you are growing, hiring, incorporating or running a contractor business.
Do you work with subcontractors who use multiple contractors?+
Yes - that is the typical CIS subcontractor pattern. We pull deductions directly from HMRC where some contractors fail to send monthly statements, reconcile every payment, identify any overdeductions, and submit the refund claim with your annual self-assessment. The fixed £350 fee covers any number of contractors you worked for during the year.
