Construction Accident Claims UK
Construction is the most dangerous industry in the UK. Builders, scaffolders, electricians, plumbers, plasterers, labourers and apprentices face risks every working day from falls, machinery, falling objects, and a hundred other hazards. When a contractor fails to plan or supervise the work properly and a worker is injured as a result, a compensation claim usually follows — whether the worker is directly employed, subcontracted, or self-employed.

Who Can Claim After a Construction Accident?
Almost anyone hurt on a UK construction site has a potential claim. The most common claimants are:
- Directly-employed construction workers — claiming against their employer
- Subcontractors and self-employed tradespeople — claiming against the main contractor or site occupier (see our self-employed accident claims guide)
- Agency workers — claiming against either the agency, the host employer, or both
- Apprentices and trainees — claiming against the contractor responsible for their training and supervision
- Visitors to the site — surveyors, inspectors, clients’ representatives, delivery drivers
- Members of the public — passers-by injured by falling materials, scaffold collapses, or unsafe site perimeters
- Families of workers killed on site — through the estate and as dependants under the Fatal Accidents Act 1976
CDM 2015 — The Backbone of Construction Safety
The Construction (Design and Management) Regulations 2015 set out duties for every party involved in a construction project — from the client who commissions the work, to the principal designer, to the principal contractor, to individual contractors, to workers themselves. Construction accident claims usually turn on whether one or more of these parties met their CDM duties.
Key duties under CDM 2015 include:
- The client must appoint a competent principal designer and principal contractor for projects involving more than one contractor
- The principal contractor must plan, manage and monitor the construction phase, including providing site induction and safe access
- Contractors must plan, manage and monitor their own work, including by providing competent supervision
- Designers must eliminate foreseeable health and safety risks where possible, and reduce remaining risks
- Construction Phase Plans must be in place before work starts and updated as the project develops
- For “notifiable” projects, the HSE must be informed in advance
- Workers must receive appropriate site induction, information and training
On top of CDM 2015, sites are covered by the Work at Height Regulations 2005 (see our falls from height claims guide), the Provision and Use of Work Equipment Regulations 1998 (PUWER), the Personal Protective Equipment at Work Regulations 1992, the Control of Substances Hazardous to Health Regulations 2002 (COSHH), and the Manual Handling Operations Regulations 1992 (see our manual handling injury claims guide). Most successful claims involve breaches of one or more of these.
Common Causes of Construction Accidents
The HSE’s annual statistics consistently show the same patterns. The most common causes of construction accidents in UK claims include:
- Falls from height — from scaffolds, ladders, roofs, MEWPs, and unguarded edges
- Being struck by moving vehicles or plant — particularly during reversing or in confined site areas
- Being struck by falling objects — tools, materials, or equipment dropped from height
- Manual handling injuries — particularly back injuries from lifting heavy materials
- Caught in or between moving machinery — excavators, dumpers, telehandlers
- Slips, trips, and falls on the same level — cluttered walkways, muddy surfaces, trailing cables
- Electrical injuries — particularly from contact with overhead or underground services
- Collapse of structures, scaffolds, or excavations
- Hand-arm vibration injuries — from grinders, breakers, hammer drills (see our VWF compensation claims guide)
- Dust and chemical exposure — silica, asbestos in older buildings, paint solvents
- Noise-induced hearing loss — from prolonged exposure to power tools and plant
What Compensation Could You Receive?
Construction accident compensation typically covers two strands — general damages for the injury and special damages for the financial impact. Typical ranges across common construction injuries:
- Moderate back injury — typically £12,000 to £30,000
- Severe back injury with permanent symptoms — typically £40,000 to £170,000
- Multiple fractures with prolonged recovery — typically £15,000 to £60,000
- Traumatic brain injury — typically £15,000 (minor) to £493,000+ (severe)
- Spinal cord injury with paralysis — typically £230,000 to over £400,000
- Amputation of a limb — typically £100,000 to £290,000 depending on which limb
- Hand or finger injuries from machinery — typically £5,000 to £75,000
- Hearing loss from prolonged noise exposure — typically £8,000 to £45,000
- Fatal accident — bereavement award plus loss of dependency under the Fatal Accidents Act 1976
Special damages cover lost earnings (past and future), pension loss, rehabilitation, prosthetics, home and vehicle adaptations, and any private medical treatment. For working-age tradespeople forced into early retirement, the loss-of-earnings figure is often the dominant component. Use our workplace accident calculator for a directional estimate.
Who Can You Claim Against?
Most construction accidents involve multiple potential defendants. A solicitor will identify all of them and bring the claim against the right combination. Defendants commonly include:
- Direct employer — for directly-employed workers
- Principal contractor — for site-wide management failures, applying to all workers on site
- Main contractor or subcontractor — for failures in their specific work
- Plant or equipment hirer — for defective or unsuitable equipment
- Designer or principal designer — where design failures created the hazard
- Manufacturer — where equipment had an inherent defect
- Site client — in some circumstances under CDM 2015
Construction defendants are usually well-insured. Most main contractors carry Employers’ Liability Insurance (mandatory) and Public Liability Insurance (industry-standard), typically at £5 million or £10 million per claim. Even where the construction company has gone out of business, the Employers’ Liability Tracing Office (ELTO) can usually identify the historic insurer.
Self-Employed Tradespeople — Do You Have a Claim?
Most successful claimants in UK construction accident litigation are self-employed or labour-only subcontractors. The legal position is clear: even if you are not an employee in the strict sense, the main contractor or site occupier owes you a duty of care for the safety of the site. CDM 2015 imposes site-wide duties that benefit all workers regardless of their employment status.
There are some practical differences for self-employed claimants:
- Loss of earnings has to be evidenced through accounts, invoices, and tax records rather than payslips
- Sick pay is not paid (most self-employed tradespeople have no employer-funded sick pay), so the time-off-work loss is usually a direct loss claimable as special damages
- The “employer” defendant is usually the main contractor or principal contractor, not your own limited company
- Public liability and CDM duties create the duty of care, not employer-employee responsibility
See our self-employed and subcontractor claims guide for more.
Time Limits
You generally have three years from the date of the accident. For cumulative injuries that develop over time (such as HAVS, hearing loss, or chronic back conditions), the three-year clock often starts from your date of knowledge — when you first realised the injury was work-related. For children injured on site, the clock does not start until their 18th birthday. In fatal cases the three years runs from the date of death. See our time limits guide for the full rules.
Evidence That Strengthens a Construction Accident Claim
A solicitor will obtain the evidence for you. Strong claims usually include:
- The accident book entry from your employer or the principal contractor
- Any RIDDOR report submitted to the HSE
- The site’s Construction Phase Plan and any risk assessments for the task
- Method statements for the work
- Photographs of the scene immediately after the accident — including conditions, equipment, and any defects
- Names of colleagues and other site workers who witnessed the accident
- Site induction records (or their absence)
- Training records for the equipment or task involved
- Equipment inspection and maintenance records
- Toolbox talk records and other safety briefings
- Any HSE investigation report or prohibition notice
- CCTV from the site if available
- Your medical records, scans, and specialist reports
Our evidence guide explains how this is then used to build the case.
No Win No Fee Construction Accident Claims
Construction accident claims run on a no win no fee Conditional Fee Agreement. You pay nothing upfront, nothing during the case, and nothing if the claim fails, provided you keep to the terms of your agreement. If the claim succeeds, the success fee — capped by LASPO 2012 at 25 per cent of general damages and past losses (future losses excluded) — is deducted from your compensation. After-the-Event insurance protects you from the other side’s costs if the case is lost. The ATE premium is normally payable only if you win, deducted from your compensation — it is no longer recoverable from the defendant — and your solicitor must explain how the premium and disbursements are treated before you sign (see how ATE insurance works). See our how no win no fee works guide.
For serious injury claims interim payments are usually available within months of the claim being notified — to fund rehabilitation, private treatment, lost earnings, and any necessary equipment.
Common Questions About Construction Accident Claims
I am self-employed. Surely I cannot claim against a main contractor?
You almost certainly can. CDM 2015 imposes duties on principal contractors and site occupiers that benefit every worker on site, not just direct employees. Most successful construction accident claims in the UK are brought by self-employed or labour-only subcontractors. See our self-employed accident claims guide.
I was at fault for the accident as well. Can I still claim?
Possibly. Construction sites involve shared responsibility — workers must take reasonable care for their own safety. If you were partly at fault, the principle of contributory negligence means your compensation may be reduced, but you can still recover most of it provided the contractor’s failures were a significant part of the cause. See our contributory negligence guide.
The HSE prosecuted my employer after my accident. How does that affect my claim?
It generally helps your claim substantially. An HSE prosecution and conviction is strong evidence of breach of duty in a civil claim. The investigation report, prosecution evidence, and any court findings can be relied on without re-proving the breach. Your solicitor will request the HSE file early in the case.
The accident was a long time ago and the company has gone bust. Can I still claim?
Possibly, depending on the time elapsed and the type of injury. For sudden accidents the three-year limit runs from the accident. For cumulative or “creeping” injuries — like HAVS, hearing loss, or some back conditions — the clock runs from your date of knowledge, which may be much later. The Employers’ Liability Tracing Office can usually identify the historic insurer of a defunct company. A free initial conversation with a specialist solicitor will give you a clear answer.
How much is a construction accident claim worth?
It depends entirely on the injury and its long-term impact. Minor injuries with full recovery may be worth a few thousand pounds. Severe injuries involving permanent disability, brain damage, or paralysis can run into hundreds of thousands or even seven figures when lifetime care and accommodation needs are factored in. Use our workplace accident calculator for a directional estimate.
How long does a construction accident claim take?
Straightforward cases that settle without court can take 9 to 18 months. More complex cases with severe injury or disputed liability can take 2 to 4 years, with interim payments available during the case for serious injuries. See our how long does a claim take guide.
