TL;DR: UK construction businesses need software that handles estimating, project management, CIS deduction workflows, and CDM 2015 documentation in a single ecosystem. Generic SME accounting packages alone do not cover the sector's compliance obligations.
Last reviewed: 12 May 2026
The Compliance Layer That Makes Construction Software Different
Construction is one of the most heavily regulated industries in the UK. The Construction (Design and Management) Regulations 2015 (CDM 2015) impose documentation duties on every project with more than one contractor. The Health and Safety Executive (HSE) enforces RIDDOR (Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 2013) across all sites. HMRC's Construction Industry Scheme (CIS) requires verification, deduction, and monthly return filing for every subcontractor payment. None of these obligations fit neatly into a standard SME accounting package. Construction software earns its cost by embedding these workflows rather than leaving site managers and finance teams to manage them manually.
The HSE's CDM 2015 Guidance makes the principal contractor responsible for coordinating the health and safety plan, maintaining the construction phase plan, and ensuring a health and safety file is handed over at project completion. Software that cannot generate, version-control, and store these documents creates a documentation gap that HSE inspectors will identify during site visits.
Estimating and Quantity Surveying Software
Accurate estimating is the financial foundation of every construction project. UK estimating software should accommodate the standard approaches recognised by the Royal Institution of Chartered Surveyors (RICS): elemental cost plans, bills of quantities (BOQ), and schedule of rates. The RICS Construction Standards provide the measurement rules (NRM2 for building works, CESMM4 for civil engineering) that software libraries should reflect.
For SME contractors, the most practical estimating features are: a material price database that can be updated against current supplier quotes, a labour rate builder that incorporates PAYE oncosts and subcontractor CIS deductions, and a markup and margin calculator that distinguishes between preliminaries, measured works, and contingency. Estimating software that exports directly to a project management module, and then feeds actuals back for cost-to-complete reporting, closes the loop between tender and delivery.
Project Management and CDM 2015 Documentation
Construction project management software must handle two distinct compliance requirements that general project management tools do not address.
First, CDM 2015 documentation. Any project where construction work is likely to last longer than 30 working days with more than 20 workers simultaneously, or exceed 500 person-days, must be notified to the HSE via F10 notification. The principal contractor must produce a construction phase plan before work starts and maintain it throughout. Software that generates an F10 directly from project data and stores it against the project record eliminates the risk of late notification, which carries enforcement action under CDM 2015 Regulation 6.
Second, RIDDOR reporting. Under RIDDOR 2013, specified injuries (fractures, amputations, loss of consciousness) must be reported to the HSE within the same working day via RIDDOR Online. Over-seven-day injuries must be reported within 15 days. Construction software with a site incident log that triggers RIDDOR reporting workflows and retains records for the mandatory three-year period supports the principal contractor's legal duty.
The Chartered Institute of Building (CIOB) notes in its Contract and Procurement Guidance that programme management, resource scheduling, and change control are the three areas where construction projects most commonly overspend. Software that tracks these in real time against the original estimate, and produces a formal variation order workflow, protects the contractor's margin on JCT and NEC contract forms.

CIS Software Requirements and HMRC Integration
The Construction Industry Scheme is one of the most administratively intensive tax obligations in UK business. Every month, a contractor must verify each new subcontractor with HMRC (either online or via the CIS API), apply the correct deduction rate (gross for verified registered subcontractors with good compliance history, 20% for standard registered, 30% for unregistered), and submit a CIS300 monthly return. Subcontractors must receive a deduction statement by the 19th of the following month.
Construction software with an integrated CIS module should handle all of these steps. For detailed guidance on CIS software requirements specifically, see Construction CIS Software UK. The key integration test is whether the software calls HMRC's CIS verification API directly, rather than requiring manual entry of verification numbers, and whether the CIS300 submission is filed via the Government Gateway API or requires manual re-entry into HMRC's online service.
Accounts and Financial Reporting for Construction
Construction accounting has two features that generic accounting software handles poorly. The first is job costing: the ability to track revenue, labour, materials, plant, and subcontractor costs against individual projects or cost codes. The second is application for payment and valuations: the construction payment cycle runs on monthly applications, architect's certificates, and retentions, which do not map to standard sales invoice workflows.
A construction accounting module should support: application for payment drafts linked to the project programme, retention tracking (5% standard, reducing to 2.5% at practical completion under standard JCT terms), and profit-and-loss reporting by project. VAT treatment in construction is complex; the domestic reverse charge introduced in March 2021 applies to most B2B construction supplies, and the software should handle this automatically, posting the correct VAT entries without manual override.
Businesses with employees on site will need payroll integration, particularly for CIS gross payment status employees whose income tax and NI must be deducted by the employer in the normal way, unlike self-employed subcontractors. Integration with payroll software (see Best Payroll Software UK) ensures that operatives on the PAYE register are correctly distinguished from subcontractors on the CIS register.
Site Safety and HSE Compliance Features
Digital site safety management is increasingly expected by main contractors and clients as a condition of appointment. Construction software in this category should handle: induction records (including evidence of CSCS card checks), plant inspection certificates, scaffold inspection logs, method statements, and risk assessments. The HSE's enforcement approach under CDM 2015 focuses on whether the principal contractor has a documented system for managing these records, not simply whether individual documents exist.
Software that generates automatic prompts for certificate renewals (LOLER inspections for lifting equipment every six months, thorough examination of pressure systems annually under PSSR 2000) reduces the compliance exposure that arises when certificates lapse unnoticed on busy sites. HSE inspectors conducting a project visit will request the current construction phase plan and the most recent scaffold and plant inspection records; software that surfaces these instantly from the project record is a practical advantage.

Frequently Asked Questions
What is the CDM 2015 F10 notification and which software generates it?
The F10 is the statutory notification to HSE required under CDM 2015 Regulation 6 for notifiable projects: those lasting more than 30 working days with over 20 simultaneous workers, or exceeding 500 person-days. Construction project management software with a CDM module should generate the F10 from project data (client details, principal designer, principal contractor, site address, start date, planned duration) and submit or export it for HSE Online submission. HSE must receive notification before the construction phase begins.
Does construction software handle the domestic reverse charge for VAT?
The domestic reverse charge for construction services, which came into effect in March 2021, requires the recipient of most B2B construction supplies to account for VAT rather than the supplier charging it. Quality construction accounting software should identify transactions that fall within the reverse charge rules and post the correct VAT entries automatically. Businesses should verify with their accountant whether their specific supply chain arrangements are within scope before relying on software automation.
How does construction software differ from standard SME accounting software?
Standard SME accounting software handles invoicing, bank reconciliation, and VAT returns but does not natively support job costing by project, applications for payment, retention tracking, CIS verification and deduction, or CDM documentation. Construction software either replaces the accounting function entirely or integrates with a standard package and adds these construction-specific modules on top. For businesses above a modest turnover, the integration approach usually provides a better audit trail.
Is RIDDOR reporting built into construction project management software?
Some construction software includes an incident reporting module that logs site accidents and generates RIDDOR-compliant records, but the actual RIDDOR notification to HSE must be made via RIDDOR Online or by telephone for fatal and specified injuries. Software can prompt the correct reporting timeline (same day for specified injuries, within 15 days for over-seven-day injuries) and store the notification reference number against the project record, but it cannot substitute for the statutory notification itself.
What RICS measurement standard should UK estimating software follow?
For building works, the RICS New Rules of Measurement Volume 2 (NRM2) governs detailed measurement for bills of quantities. For civil engineering works, the Civil Engineering Standard Method of Measurement (CESMM4) applies. Estimating software used for public sector or main contractor tendering should support the measurement library relevant to the work type. The RICS publishes current guidance on measurement standards at rics.org.
