Edge protection is one of the most price-sensitive procurement decisions on a construction site — and one of the most consistently misunderstood. Comparing systems on day rate or purchase price alone systematically ignores the operational, financial, and safety costs that accumulate across the life of a project and the life of a fleet. This article sets out the full cost picture — and explains why an engineered system with a 20+ year lifespan is not an expensive choice. It is the most cost-effective one.
Why Purchase Price Is the Wrong Starting Point
The instinct to minimise the unit cost of edge protection is understandable. On a construction budget under pressure, every line item is scrutinised, and temporary works are often treated as a commodity. But edge protection is not a commodity. It is a structural safety system that interacts with your programme, your labour costs, your slab finishes, your site health management, and your fleet economics, in ways that a day rate comparison will never capture.
The question is not what does this system cost to hire or buy? The question is what does this system cost to own and operate across the full life of a project, and across the full life of a hire fleet?
When that question is asked properly, the answer changes the procurement decision.
The Five Cost Categories That Day Rate Ignores
1. Installation and Strike Labour
Labour is the largest cost on most construction sites, and it is rising. According to the BCIS, construction labour costs rose by 7.1% year-on-year by mid-2025, driven by rising employer National Insurance contributions and a higher National Living Wage. The CITB’s Construction Workforce Outlook 2025–29 projects a need for nearly 48,000 additional workers per year through to 2029, keeping skilled labour tight and expensive.
An edge protection system that installs in seconds per post rather than minutes directly reduces the labour cost of every installation and strike cycle. On a 30-storey concrete frame where edge protection must move upward with the build, installed and struck on every floor, the cumulative saving over the programme is significant.
A drill-and-fix post requires a team to drill into the slab, insert chemical or mechanical anchors, torque to specification, and reverse the process on removal. A tool-free compression post installs by hand, without any of those steps, and strikes just as quickly. The Rapid Post installs ten times faster than a conventional drill-and-fix post, and six times faster than any other compression post on the market. On a live programme, that differential is a measurable labour cost saving, not a specification detail.
2. Slab Remediation Costs
Drill-and-fix edge protection leaves anchor holes in the slab that must be made good before floor finishes can proceed. On a residential high-rise, where each floor will be handed over to screeding or fit-out contractors, remedial repair to a standard acceptable for floor finishes must be completed, in materials, labour, and programme time.
This cost is almost never included in the procurement comparison. On a 200-post floor across a 30-storey programme, it is not a rounding error. It is a material cost that belongs in the total cost analysis, and that is entirely eliminated by a compression post system that leaves no slab penetration.
3. COSHH Obligations and Silica Dust Management
Drilling into concrete generates respirable crystalline silica (RCS) dust, a serious and well-documented occupational health hazard. The HSE links prolonged RCS exposure to silicosis, lung cancer, and COPD, and estimates over 500 construction workers die from silica-related disease every year. COSHH Regulations require that exposure is controlled, which means respiratory protective equipment (RPE), local exhaust ventilation (LEV), wet suppression, and documented risk assessments.
All of this takes time, costs money, and adds administrative overhead to site management. For a hire company whose operatives install and strike edge protection repeatedly across multiple sites, the cumulative cost of managing silica dust from edge protection installation is not trivial, and the health liability is real.
A compression post system eliminates the need to drill entirely. No drilling means no silica dust from edge protection installation, which removes the associated COSHH obligations, reduces the RPE burden on operatives, and simplifies site health management.
4. Programme Time — The Compounding Cost
Analysis by Elecosoft notes that on a project valued at £25 million running over two years, even modest programme delays can translate into hundreds of thousands of pounds in additional costs when cascading effects, equipment hire extensions, insurance premium increases, management overhead, are fully accounted for.
Edge protection is not typically the primary driver of programme delay. But it is one of the factors that quietly absorbs time on every floor cycle. A system that installs and strikes in a fraction of the time of an alternative does not just save a few hours. Across a 25-storey programme with weekly floor cycles, that efficiency compounds into days saved on the overall schedule, which translates into real programme value.
The fixing centre of the post compounds this further. A system with 2.7m fixing centres, the widest in the market, offered by the Rapid Post, requires fewer posts per metre of edge than a 2.4m system. Fewer posts means fewer deliveries, less crane time, less site storage, and a faster installation on every cycle.
5. Fleet Replacement Cost — The Biggest Long-Term Factor
For hire companies and contractors who own their fleet, the lifespan of edge protection equipment is the single biggest determinant of total cost of ownership. A system that lasts three to five years before requiring significant component replacement will be purchased multiple times over the life of a hire business. A system engineered to last 20 years or more represents a fundamentally different capital commitment.
Rapid-EPS products are engineered for a 20+ year product lifespan, the longest in the industry. This is not a marketing position. It is an engineering decision built into the specification of every component: the substrate preparation and coating systems used to resist site environment degradation; the structural design of connections that can withstand hundreds of hire cycles; the material specification of every structural element.
Over a 20-year period, the total cost of ownership of a well-maintained, premium-engineered system is significantly lower than a cheaper alternative purchased multiple times. The comparison is not the same system at different price points. It is a different system over a different lifetime.
What ‘Cheap’ Actually Costs Over Time
A system priced at 30% less than a premium alternative is not 30% cheaper if it lasts a third as long, costs twice as much to install per cycle, requires slab remediation at every removal, and generates COSHH obligations that add management time and health risk to every job.
The real cost of a cheap edge protection system is rarely visible at the point of purchase. It emerges gradually, in the labour hours spent on slow installations, the repairs to slab finishes, the COSHH documentation, the equipment that needs replacing sooner than expected, and the programme days lost to slower floor cycles. By the time these costs are visible, they are already spent.
This is why the most commercially sophisticated hire companies and contractors in the UK have moved away from day-rate comparisons and toward whole-life cost analysis when evaluating edge protection systems. It is also why projects like Karlatornet in Gothenburg, Atlantis The Royal in Dubai, and One Blackfriars in London chose Rapid-EPS, because on a complex, high-value build, the true cost of getting edge protection wrong is not the invoice. It is the programme.
The Rapid-EPS Cost Equation
Rapid-EPS is not the cheapest edge protection system on the market. It is the most cost-effective over time. The distinction matters.
When the full cost picture is considered, labour, remediation, COSHH, programme time, and fleet replacement, a system that installs ten times faster, requires no drilling, leaves no slab damage, and lasts 20+ years with proper maintenance delivers a total cost of ownership that a cheaper, shorter-life alternative cannot match.
Here is what that means in numbers:
- A 30-storey high-rise with a 200-metre perimeter uses approximately 75 posts per floor at 2.7m fixing centres, versus 84 posts at 2.4m. Over 30 floors, that is 270 fewer posts to handle, move, and store.
- Installing and striking each post 10x faster than drill-and-fix, across 30 floor cycles, represents a substantial reduction in installation labour — on a programme where that labour is both expensive and in short supply.
- Zero slab penetration means zero remedial repair cost across every floor — a cost that is consistently underestimated at procurement but consistently appears in final accounts.
- A 20+ year product lifespan means a hire fleet purchased once performs across two decades — rather than being replaced every three to five years at significant capital cost.
The Procurement Conversation That Changes the Decision
The most effective way to change an edge protection procurement decision is to change the question being asked. Instead of: what is the day rate? ask:
- What is the total installation and strike labour cost across the full programme?
- What are the COSHH obligations associated with the installation method, and what do those cost to manage?
- What are the slab remediation costs on removal?
- What is the expected product lifespan, and what is the replacement cost profile over 10 and 20 years?
- What is the programme impact of a faster installation system across the full floor cycle count?
When procurement decisions are framed by these questions rather than the invoice price, the Rapid-EPS value proposition is not a difficult one to make. It is the one that the numbers support.
In Summary
The true cost of edge protection is not on the invoice. It is in the labour, the programme, the slab, the site health management, and the fleet. Buyers and specifiers who evaluate systems on day rate alone will consistently undervalue what a genuinely engineered system delivers — and overpay for the consequences of a cheaper one.
Rapid-EPS products are engineered for a 20+ year lifespan, install ten times faster than drill-and-fix, require no slab penetration, and carry industry-leading 2.7m fixing centres. The total cost of ownership over the life of a project and the life of a fleet is consistently lower than alternatives that appear cheaper on the initial invoice.
That is not a claim. It is the arithmetic.
