Builders portable toilet hire cost is one of those small site budget lines that can quietly grow, because the weekly rate you see advertised is rarely the whole bill. Delivery, collection, minimum hire periods, VAT and the type of unit all change the final figure, and the prices published online vary a great deal from one source to the next. This guide brings together current supplier price lists and official Health and Safety Executive (HSE) guidance so you can budget with realistic numbers and compare quotes fairly.
Quick Facts
| Item | Typical figure reported by suppliers | Notes |
|---|---|---|
| Basic cold-water chemical unit | About £25 to £75 per week | Weekly servicing is usually included; the low end is common outside London |
| Hot-water chemical unit | About £42 to £62 per week | Two suppliers’ published lists |
| Mains-connected (240V) unit | £65 to £70 per week | One supplier’s list |
| Accessible unit | £75 to £120 per week | One supplier’s list |
| Delivery and collection | Roughly £24 to £150 per trip | Very wide range; depends on distance and whether pricing is per unit or per job |
| Minimum hire period | Often 2 to 4 weeks | Varies by supplier and unit |
| Toilets needed | 1 for every 7 people on a 40-hour week | HSE guidance for portable chemical toilets |
| VAT | Usually quoted excluding VAT | Add VAT where it applies to your business |
Why the Prices You Find Online Do Not Agree
One price guide aimed at homeowners and tradespeople on MyBuilder lists a standard portable toilet at roughly £75 to £150 per week, while several specialist site-toilet suppliers publish weekly rates for a basic chemical unit of about £25 to £75. The reason for the gap is not publicly confirmed, but a likely explanation is that broad guides blend short event hires, luxury units and site hires together, whereas supplier lists describe long site hires with weekly servicing and a minimum term.
It is also worth treating many of the search results with caution. Most published prices come from the suppliers themselves, and some of the pages that appear for this topic look like republished copies of the same generic article, with figures in dollars or with no named source. Use any single number as a rough guide only, and ask for at least two written quotes before you commit.
What Drives Builders Portable Toilet Hire Cost
Hire length and minimum terms
Longer hires almost always work out cheaper per week, because the delivery and collection charge is a fixed cost that gets spread across more weeks, according to Sitech Loos London. Minimum terms differ between suppliers. Site Equip, which covers the south of England, lists a four-week minimum on its chemical site units, while a supplier whose price sheet appears in a 2025 parish council document applies a two-week minimum.
Unit type
A basic cold-water chemical unit is the cheapest option, and costs rise as you add features. Hot-water units, mains-connected units and accessible units all sit higher on the price lists, and Sitech lists scaffold-mounted installation from £75 per week. The table below shows how the main types compare, and it is the simplest way to see how builders portable toilet hire cost shifts once a job needs more than the basic option.
| Unit type | Reported weekly rate |
|---|---|
| Cold-water chemical toilet | About £25 to £37 at Site Equip depots; £32 to £75 at Sitech (higher end is central London) |
| Hot-water chemical toilet | £42 (Site Equip) and £44 to £62 (Sitech) |
| Mains-connected 240V toilet | £65 to £70 (Sitech) |
| Accessible or disabled-access toilet | £75 to £120 (Sitech) |
| Scaffold-mounted installation | From £75 (Sitech) |
Location and access
London jobs tend to cost more. Sitech quotes £40 to £75 per week in central London compared with rates from £32 elsewhere, and central London deliveries can also pick up congestion charge or ULEZ costs. Outside London, Site Equip notes that the price depends partly on how far the site is from its depots in Hampshire and Kent.
Number of units
Ordering several units at once can lower the per-unit cost when the supplier services them in a single visit. Pricing models differ, though. The parish council document mentioned earlier shows delivery and collection charged per unit, at £24 plus VAT each way for one unit and £48 plus VAT each way for two, which is a very different structure from a flat charge per job.
Delivery, Collection and Other Extras
Weekly hire normally covers servicing, which means waste removal, cleaning, chemical recharge and restocked toilet paper, and suppliers such as Site Equip and Sitech state this on their price pages. The extras are where quotes start to diverge. Sitech lists delivery and collection at around £30 to £40 each way, while another UK rental guide says to expect £50 to £150 per trip depending on distance from the depot, so it pays to confirm whether the charge applies per job or per unit.
Other costs to ask about include VAT, insurance against damage or theft, which one supplier offers as an optional extra without publishing a standard price, and any charge for extra servicing. That last point matters on busy sites, because HSE guidance says daily cleaning may not be enough for site toilets, and a standard weekly service might leave a crowded site short. How much a supplier charges for additional visits is not publicly standardised, so it needs to be asked.
To see how builders portable toilet hire cost builds up over a month, take a single standard unit on a four-week hire, using the published ranges above and excluding VAT:
- Outside London: four weeks at £32 is £128, plus £60 to £80 for delivery and collection, which gives about £188 to £208.
- London: four weeks at £40 to £75 is £160 to £300, plus the same £60 to £80 for transport, which gives about £220 to £380.
These are illustrative calculations based on one supplier’s published rates, not quotes, and your own figure will depend on the supplier, distance and unit type.
How Many Toilets a Building Site Needs
HSE says that if you use portable chemical toilets, you need one for every seven people working a 40-hour week. A site with ten workers would therefore need two units, and the number rises in steps of seven, so fifteen workers would need three. Some supplier pages and blogs quote different ratios, such as one toilet for every five people or one for every 25, and these do not match the HSE construction guidance, so it is safer to plan around the HSE figure and the legal standard that facilities must be suitable and sufficient.
HSE also describes chemical toilets as a last resort. Its preferred order is flushing toilets connected to mains water and drainage, then units with a built-in water supply and drainage tank, and only then portable chemical toilets. On a longer project where a mains connection is realistic, it is worth asking whether a mains-connected unit, at around £65 to £70 per week on the one list that publishes it, is a better fit than several basic chemical units.
Ways to Keep Builders Portable Toilet Hire Cost Down
Match the hire period to the real programme
Because delivery and collection are largely fixed charges, booking for a realistic duration and avoiding a series of short hires usually gives a better weekly rate. If the job may overrun, ask what the weekly rate is after any minimum term ends, since several suppliers say they keep extra-week costs low for long hires.
Compare quotes like for like
When you compare builders portable toilet hire cost across suppliers, line up the same details in each quote: the weekly rate, the minimum term, whether delivery and collection are charged per unit or per job, how often the unit is serviced, whether consumables are included, and whether VAT is on top. A quote that looks cheap per week can end up costing more once a four-week minimum or a per-unit transport charge is added.
Group units and keep the site ready
A single servicing visit for several units tends to keep the per-unit rate lower, so placing units together where the layout allows is sensible. Having the site ready on delivery day also helps you avoid wasted trips, which is covered in the FAQ below.
Frequently Asked Questions
Can I hire a portable toilet for just a few days?
Yes, but the economics change. Sitech says its hire is priced by the week and that short or weekend hires are quoted per job, because delivery and collection make up most of the cost on short stays. Some suppliers also set a minimum of two or four weeks, so a few days on site may still be charged as the minimum term.
Do I pay for weekends?
It depends on the supplier. The supplier in the parish council document charges for five days, Monday to Friday, and not the weekend, while many others quote a flat weekly rate. Ask which basis your quote uses, especially if the site only runs on weekdays.
Do site toilets need hot water?
HSE guidance says there should be washbasins with hot and cold, or warm, running water next to the toilets, along with soap and towels or hand dryers. One supplier describes hot water as strongly recommended rather than legally required on every site, so the wording differs between sources, but a hot-water unit at about £42 to £62 per week is the simple way to meet the HSE expectation.
Where can the toilet be placed?
Site Equip says its units must sit on flat ground within three metres of vehicle access, and that its drivers cannot lift a toilet over a fence. If your site is tight, a walled garden or a rear plot, check with the supplier first, because an unsuitable position can mean a failed delivery.
How much does a welfare unit cost compared with a single toilet?
A towable or cabin-style welfare unit, which combines a toilet with a rest area, is priced differently from a single toilet, and Site Equip says most have a four-week minimum with delivery, collection and VAT added on top. A standard weekly figure is not publicly confirmed across suppliers, so you will need a quote based on your location and hire length.
Should I take the optional insurance?
One supplier offers insurance on its portable toilets at an extra cost, but a typical price is not publicly confirmed. Read the hire terms for who is responsible for damage, theft and vandalism, then decide whether the extra premium is worth it for your site’s security.
Conclusion
Builders portable toilet hire cost depends far less on the headline weekly rate than on the hire length, unit type, location and how delivery is charged, so the most reliable way to budget is to plan toilets around the HSE ratio and then compare written quotes on identical terms. Published supplier rates suggest that a basic unit starts at about £25 to £32 per week outside London and rises with extra features, but the numbers online conflict, and a firm quote for your postcode and programme will always be more useful than an average.
