Construction firms can set up group health insurance from just 2 employees, typically at £35–£110 per employee per month. The big win is musculoskeletal care: private physio and scans within 1–2 weeks, against an NHS trauma and orthopaedics median wait of 14.1 weeks. Employees on payroll qualify; self-employed CIS subcontractors generally need their own policies.
- ✓NHS trauma and orthopaedics median wait is 14.1 weeks — private scans take 1–2 weeks.
- ✓Group schemes start at 2 employees; CIS subbies generally aren't eligible and need personal cover.
- ✓Cash plans from a few pounds per head suit high-turnover crews who need physio, not surgery cover.
Why construction firms buy health insurance
Musculoskeletal problems — backs, knees, shoulders, hips — are the dominant cause of ill health in construction, and they're exactly the conditions the NHS is slowest to treat. The median NHS wait for trauma and orthopaedics is 14.1 weeks, and around 1 in 12 patients wait 41.8 weeks or more. For roughly 1 in 4 diagnostic tests, the wait is six weeks-plus before anyone even knows what's wrong.
The NHS is brilliant. The waiting isn't — and in a trade where people earn with their bodies, waiting is expensive twice over. UK employees average 9.4 sick days a year, and absence costs employers around £103bn annually. On site, one missing bricklayer or electrician can stall a whole sequence of work.
There's a commercial angle too. Main contractors increasingly ask about workforce wellbeing in pre-qualification questionnaires, and a health scheme is concrete evidence rather than a policy statement. It also helps recruitment in trades where skilled labour is scarce: health cover is consistently the most-valued voluntary benefit among UK employees, and relatively few small construction firms offer it — so the ones that do stand out.
What a construction scheme costs
Group health insurance for a construction firm sits in the same range as other small businesses: £35–£110 per employee per month, with a UK average around £57. Age is the biggest driver — a young site crew prices well below an office of fifty-somethings. Insurance premium tax at 12% is included in quotes.
| Team profile | Sensible cover shape | Indicative cost per person/month |
|---|---|---|
| Young crew (20s–30s), 3–5 people | Core cover plus outpatient limit for physio and scans | £38–£55 |
| Mixed-age firm of 8–15 | Mid-range with full diagnostics and therapies | £55–£80 |
| Directors and senior staff only | Comprehensive, low excess | £75–£110 |
| High-turnover labour force | Health cash plan instead | £5–£15 |
For most construction firms the priority is outpatient cover — that's where physiotherapy, consultations and MRI scans sit. A policy with good outpatient and therapies cover but a sensible excess usually beats a gold-plated hospital plan for a site-based team. Our business health insurance cost guide breaks down the levers in detail.
Employees vs CIS subcontractors: who can actually join
Employee-versus-subcontractor eligibility is the question that trips up most construction firms. Group health insurance covers employees — people on your payroll. Genuinely self-employed subcontractors paid under the Construction Industry Scheme (CIS) are running their own businesses, and insurers generally won't let you add them to your group policy.
- PAYE employees. Eligible. Site managers, direct labour, office staff, apprentices — anyone on payroll can join from 2 employees upwards.
- Directors. Eligible, including working directors of the firm. Many construction schemes start as director-plus-key-staff cover and grow from there.
- CIS subcontractors. Generally not eligible for your group scheme. They can buy personal cover as self-employed workers — a healthy 30-year-old pays from around £38 a month.
- Long-term labour-only subbies. A grey area. A few insurers will consider regular, exclusive subcontractors case by case, but don't assume — and be careful, because treating subbies like employees for benefits can muddy their employment status.
Compare health insurance for your firm
Does manual work make cover harder to get?
Less than you'd think — but it's worth being honest about how underwriting works. Private medical insurance prices mainly on age, location and cover level, not occupation, so a scaffolder and an accountant of the same age typically pay similar premiums. What matters is medical history.
Small construction groups (typically 2–14 employees) are usually offered moratorium underwriting: conditions from the last five years are excluded, but generally become eligible again after two years without symptoms, treatment or advice. If half your crew has an existing bad back on their records, those specific backs won't be covered at first — new injuries and unrelated conditions will be. Larger groups may qualify for medical history disregarded terms, which cover pre-existing conditions from day one. Our underwriting guide explains both.
One honest caveat: health insurance is treatment cover, not injury compensation. Accidents at work still go through your employers' liability insurance; PMI's job is getting the person diagnosed, treated and back on site quickly, whatever the cause.
The cash plan alternative for high-turnover crews
If your labour force changes month to month, full medical insurance can feel like the wrong shape — you're adding and removing members constantly, and the people you cover in March may be on someone else's site by June. A health cash plan is often the better fit: for a few pounds per person per month it pays fixed cash amounts towards physiotherapy, osteopathy, chiropractic, dental and optical costs.
It won't fund private surgery or jump a diagnostic queue, but for a workforce whose main need is quick access to physio, it delivers most of the day-to-day value at a fraction of the price. Plenty of construction firms run a hybrid: full group health insurance for directors, managers and long-serving staff, and a cash plan across the wider crew.
Frequently asked questions
Can a construction company get group health insurance?
Yes. Insurers including Bupa, AXA Health, Aviva and Vitality offer group schemes to construction firms from just 2 employees on payroll. Manual trades aren't excluded, and premiums are driven mainly by age and cover level rather than occupation. Typical cost is £35–£110 per employee per month.
Can CIS subcontractors join a construction firm's health insurance scheme?
Generally no. Group schemes cover employees on payroll, and genuinely self-employed CIS subcontractors don't qualify. They can buy personal policies instead — from around £38 a month for a healthy 30-year-old. A few insurers consider long-term labour-only subbies case by case, but it's the exception.
Is health insurance more expensive for builders and manual trades?
Not usually. Private medical insurance prices on age, postcode and cover level rather than occupation, so tradespeople typically pay similar premiums to office workers of the same age. Where manual work does raise prices is income protection and life cover — different products with occupation-based underwriting.
Does construction health insurance cover back injuries and joint problems?
New musculoskeletal conditions, yes — that's the main reason construction firms buy it. Physio, consultations, MRI scans and surgery for backs, knees, shoulders and hips are core benefits. Existing injuries from the past five years are usually excluded under moratorium terms until two trouble-free years have passed.
How fast can an injured worker get an MRI scan privately?
Typically within 1–2 weeks of a GP or consultant referral, with the consultation itself often within days. On the NHS, around 1 in 4 diagnostic tests involves a wait of six weeks or more, and the trauma and orthopaedics median wait is 14.1 weeks.
Are injuries that happen on site covered by the company's health insurance?
Treatment for the injury is generally covered like any other eligible condition — the policy doesn't ask whether it happened at work. But health insurance isn't compensation: workplace accident claims still run through your employers' liability insurance. PMI's role is speeding up diagnosis, treatment and return to site.
Is a health cash plan better than health insurance for a construction crew?
For high-turnover crews, often yes. Cash plans cost a few pounds per person monthly and pay towards physio, osteopathy, dental and optical — the things site workers actually use most. They don't cover private surgery. Many firms run PMI for the core team and a cash plan for the wider workforce.
Is health insurance for construction staff tax deductible?
Generally yes — premiums for employees are normally an allowable business expense for corporation tax. Employees pay benefit-in-kind tax on the cover, and the company pays Class 1A National Insurance at 15%. Our tax deductibility guide has the full picture; this isn't tax advice.
How many employees does a construction firm need for a group scheme?
Two. A husband-and-wife building firm, a director plus one site manager — that's enough for group pricing, which typically runs 10–30% cheaper per head than individual policies. There's no need to cover every employee, provided you use objective criteria such as role or length of service.
