Accountants for engineering contractors

Limited company accounting for engineering contractors in London and the surrounding areas, built around how the sector actually trades.

What this means for your company

Engineering, energy and infrastructure contractors on day rates through a limited company face the same statutory deadlines as any UK company, plus a handful of issues that are specific to the sector. We set the bookkeeping, VAT and reporting up around those issues rather than treating every company the same.

Long site-based contracts and the temporary workplace test for accommodation and travel

03

04

Income arriving in large irregular payments, and reserving tax before it is spent

05

Company pension contributions as the most efficient extraction route on high day rates

Year-end accounts, corporation tax and director Self Assessment

What matters most for engineering contractors

Engineering, energy and infrastructure contractors on day rates through a limited company.

• Long site-based contracts and the temporary workplace test for accommodation and travel

• Overseas assignments, double tax treaties and residence for the director

• Professional indemnity, licences and subscriptions claimed correctly

• Income arriving in large irregular payments, and reserving tax before it is spent

• Company pension contributions as the most efficient extraction route on high day rates

The compliance baseline

Whatever the sector, the company must file accounts with Companies House nine months after the accounting reference date, file a CT600 within twelve months of the period end, pay corporation tax nine months and one day after the period end, and file a confirmation statement each year.

Once taxable turnover passes £90,000 in a rolling 12 months, VAT registration and Making Tax Digital filing follow. Employing anyone, including a director on a salary, brings PAYE, RTI reporting and auto-enrolment pensions.

Thresholds, rates and deadlines quoted here reflect the 2026/27 UK position. Check current GOV.UK guidance, or ask us, before you rely on them for your own company.

Working with us

We agree the scope and monthly fee before starting, set up bookkeeping that fits how you invoice and buy, and send reminders ahead of every filing date.

You get plain answers to sector questions in normal language, and we say clearly when something needs specialist advice rather than guessing.

Frequently asked

Accountants for engineering contractors: questions directors ask

Can my company pay for accommodation near a long contract?

Yes while the site is genuinely a temporary workplace, but once you expect to be there for more than 24 months the relief stops from the date that expectation arises, not the date you pass 24 months. That timing catches most engineering contractors out.

Do you work with engineering contractors outside London?

Yes. Our focus is London, Morden, Croydon and the surrounding boroughs, but filing is digital and we work with engineering contractors across the UK.

What records are needed for accountants for engineering contractors?

Keep bank statements, sales and platform reports, purchase invoices, payroll records, VAT workings, finance agreements and Companies House correspondence. We confirm the exact list at onboarding and identify gaps before a filing deadline becomes urgent.

How much does help with accountants for engineering contractors cost?

The fee depends on transaction volume, record quality, VAT and payroll requirements, historic catch-up and the level of reporting needed. We agree a fixed scope and price before technical work starts, with published packages available on our fees page.

Can you take over accountants for engineering contractors from another accountant?

Yes. We request professional clearance, collect the prior records and authorities, check the next Companies House and HMRC deadlines, and give you one clear handover list. The process is normally completed remotely.

Can accountants for engineering contractors be handled online?

Yes. We work through secure cloud records, scheduled reviews and digital approvals, while keeping a named team available by phone, video call and email. Clients can also visit our Morden office by appointment.

Which accounting software works best for accountants for engineering contractors?

We regularly work with Xero, QuickBooks, FreeAgent, Sage and connected sales or expense apps. The right setup depends on transaction volume, integrations and the reports you need, not simply the software brand.

What tax deadlines matter for accountants for engineering contractors?

The relevant calendar may include annual accounts, Corporation Tax payment and return dates, confirmation statements, VAT returns, payroll submissions and Self Assessment. We map the dates from your company year end and registrations.

Can I get free basic tax advice about accountants for engineering contractors?

Yes. You can ask a straightforward initial question without charge. Calculations, filings, written advice, planning and HMRC correspondence are scoped and quoted before work begins.
