The Complete UK Guide to Correx Costs, Quantities, Reuse and Buying Decisions
Last reviewed: July 2026 Author: M Zelouf, Trades International
Executive Summary
When UK tradespeople ask questions like:
- Is correx worth the money?
- How much correx do I need?
- Is it cheaper to buy in bulk or pick up as needed?
- Can correx be reused?
- Should I buy 2mm or 3mm?
- Does free next working day delivery actually save money?
they're really asking one question: what's the most economical way to protect finished floors on a job?
At Trades International, we supply TI-Pro® Protection Boards to builders, decorators, flooring installers, kitchen fitters and refurbishment contractors across the UK. This guide sets out the actual maths behind those decisions. We discuss coverage per sheet, quantity per project type, bulk vs trade counter pricing, and the hidden costs that matter more than the price on the sheet.
Quick Answers
| Question | Answer |
|---|---|
| Is correx worth it? | Yes. Protecting a finished floor costs a fraction of repairing or replacing one. |
| What thickness should I buy? | 2mm suits most decorating, refurbishment and second-fix work; 3–4mm suits heavy foot traffic or plant/equipment crossing the surface. |
| How much do I need? | Measure the area being protected (not total floor area), add 10% for waste, divide by 2.88 m² per standard sheet. |
| Is bulk buying actually cheaper? | Yes. Bulk online pricing runs roughly 50% below typical trade counter pricing per sheet. |
| Can correx be reused? | Yes, if stored flat, dry, and handled carefully when removing tape. |
| Does free next-day delivery matter? | Yes. Avoiding labour downtime while waiting on stock usually outweighs any saving from shopping around. |
Is Correx Worth the Money?
Short answer: yes. Temporary floor protection is one of the cheapest materials on most jobs, yet it sits between the trade and some of the highest-value finishes on site — engineered timber, porcelain tile, LVT, natural stone.
When weighing up the cost of correx against the alternative, the comparison isn't "£2 a sheet vs nothing" . It's £2 a sheet against the cost of:
- replacing damaged flooring
- an unplanned return visit
- a dissatisfied client
- a delayed handover
The Health and Safety Executive also treats good housekeeping and safe, unobstructed walking surfaces as a standard part of site safety practice, which floor protection contributes to directly on active sites. If you want to dive deeper into HSE, read these articles:

What Does Correx Really Cost? (The Full Picture)
Professional contractors rarely judge floor protection on the price of a single sheet. The real comparison is the total cost of protecting the project:
| Cost component | Included in "per sheet" price? |
|---|---|
| Product price | ✓ |
| Delivery | Sometimes |
| Labour downtime waiting on stock | ✗ |
| Emergency re-orders | ✗ |
| Replacement flooring if unprotected | ✗ |
| Return visits | ✗ |
| Reuse value across future jobs | ✗ |
This is why the cheapest sheet isn't automatically the cheapest decision. Also it's important to factor in how you buy as well as the unit price.
Bulk Buying vs Trade Counter: What's the Saving?
This is the single biggest item that most contractors haven't calculated properly.
Trade counter / cash-and-carry pick-up: pricing varies a lot by branch and whether a trade account discount applies, but a realistic range for casual pick-up is roughly £4.00–£4.50 per sheet.
Buying online in bulk: standard 2mm sheets are typically listed from around £2.99 per sheet in small packs, dropping to roughly £2.00 per sheet at full bulk/pallet tiers.
| Method | Price per sheet | Saving vs counter |
|---|---|---|
| Trade counter pick-up | ~£4.25 (midpoint) | — |
| Online, small pack | ~£2.99 | 30% |
| Online, bulk/pallet tier | ~£2.00 | 53% |
What this looks like per year
Using sheets/year × price difference per sheet:
- A decorator using ~480 sheets/year (roughly 2 jobs a month, 20 sheets a job) saves approximately £1,080/year buying bulk instead of counter pick-up.
- A fit-out contractor using ~1,800 sheets/year saves approximately £4,050/year.
Of course, these are illustrative savings but the level of savings (~50%) holds fairly consistently across volumes. You can calculate your own sheets-per-job and jobs-per-year for an accurate figure.
How Much Correx Do You Need?
Every standard correx sheet measures 2.4m x 1.2m giving 2.88 m² of coverage per sheet. The working formula:
Area to protect (m²) × 1.1 (waste allowance) ÷ 2.88 = sheets needed
Measure the area actually being protected. Sometimes it will be the hallways, stairs and the rooms being worked (but of course not the total floor area of the property), since furnished or untouched rooms typically aren't covered.
| Project type | Typical area protected | Sheets needed |
|---|---|---|
| Single room + access route | 15–20 m² | 6–8 |
| Small terrace, full redecoration | 45–55 m² | 17–21 |
| Average semi/terrace, whole-house job | 60–75 m² | 23–29 |
| Small office fit-out | 30–90 m² | 12–34 |
| Full-floor office fit-out | ~380 m² | ~145 |
What's the Biggest Hidden Cost?
Running out of stock mid-job. An unplanned order typically means:
- emergency delivery charges
- a delayed trade waiting on materials
- rearranged scheduling
- customer frustration at a stalled job
This is why we recommend calculating quantity properly up front and adding roughly 10% for cuts, waste and awkward layouts. While this feels like waste, the costs of coming up short are even higher.
Does Free Next Working Day Delivery Actually Save Money?
Delivery reliability is often treated as a convenience. In practice, it's part of the job's economics. If protection boards (or any critical supplies) don't arrive on time, contractors can face idle labour, a delayed handover to the next trade, or a wasted return journey to collect more stock.
Compare the costs of bulk buying, online and trade counter Correx purchases.
Trades International keeps Correx, TI-Pro® Protection Boards in stock for free next working day delivery across most of the UK, precisely because a missed delivery slot usually costs a contractor more in downtime than any saving from shopping around on price.

Why Is 2mm Correx the Most Common Choice?
For most residential and light-commercial work, 2mm strikes the best balance of protection, weight and cost. Typical applications:
- Decorating and painting
- Kitchen installation
- Residential refurbishment
- Property maintenance
- Second-fix carpentry
For heavier traffic, you'll want something that can hold up better. For pallet trucks, ongoing multi-trade sites you may want something thicker like a 3mm or 4mm board.
Can Correx Be Reused?
Yes, and it should be in order to save margin. Provided Correx has been looked after:
- Store sheets flat, not leant or curled
- Keep them dry
- Remove tape carefully to avoid tearing the surface
- Separate damaged boards from stock still fit for reuse
- Avoid unnecessary cutting where a smaller offcut would do
Reusing boards also supports the UK's waste goals, which prioritises reuse ahead of recycling or disposal. Read more about that initiative at the gov.uk guidance on applying the waste hierarchy
Should You Buy Extra Correx?
Usually, yes. Ordering roughly 10% over your calculated quantity is typically far cheaper than a mid-job emergency order when you consider the direct cost and lost time.
Should You Buy the Cheapest Correx?
Price matters, but so do stock availability, delivery reliability, and whether the boards are fit for reuse afterwards. The lowest price per sheet isn't always the lowest-cost outcome once downtime and reorders are factored in.
How Do Professional Contractors Reduce Their Floor Protection Costs?
- Measure the area accurately before ordering
- Choose the right thickness for the job
- Order the full project quantity in one delivery
- Avoid emergency reorders
- Store boards properly for reuse
- Buy from a supplier with reliable stock and delivery
