Free Mini-Mix Concrete Price Estimator – Updated 2026 Prices
Enter your concrete requirements to estimate the cost of volumetric (mini-mix) concrete delivered to your site. Volumetric mixers blend concrete on site at the point of delivery — you pay only for what you use, with no minimum order and no short-load charges. The calculator also shows how volumetric concrete compares in cost to ready-mix truck delivery and bagged concrete for your volume.
Volumetric concrete — commonly known as mini-mix concrete in the UK — is concrete that is mixed on site at the point of delivery, rather than pre-batched at a central plant and delivered in a rotating drum truck. A volumetric mixer (also called a volumetric concrete mixer or mobile mixer) is a specialised lorry that carries separate compartments of dry cement, aggregate (sand and gravel or all-in ballast), water, and admixtures. As the vehicle is stationed at the delivery point, these ingredients are metered into an on-board mixing auger in the correct proportions and discharged as freshly mixed concrete directly into the pour. The customer pays only for the volume of concrete actually discharged — not for a minimum truck load.
Volumetric concrete has become one of the most popular concrete supply methods for UK residential, small commercial, and groundworks projects in 2026, primarily because it solves the two most significant problems with standard ready-mix truck delivery: the minimum order constraint (most ready-mix plants require a minimum of 3–6 m³, with significant short-load surcharges for smaller orders) and the access constraint (a fully loaded 8-wheel ready-mix truck weighs approximately 26–30 tonnes and requires a wide, load-bearing access route). Volumetric trucks are typically smaller and more manoeuvrable than drum ready-mix trucks, and because the customer pays per m³ delivered with no minimum order, there is no financial penalty for ordering the exact quantity needed.
In 2026, volumetric concrete costs between approximately £110 and £200 per m³ depending on mix grade, region, and access conditions, plus a call-out / mobilisation fee of approximately £80–£200. This per-m³ rate is typically 15–35% higher than equivalent drum ready-mix concrete, but the elimination of the short-load surcharge and the no-minimum-order flexibility mean that for pours of 0.5–3 m³, volumetric is often the most cost-effective option overall. For very small volumes (under 0.3 m³), bagged concrete mixed on site may still be cheaper. For pours over approximately 4–5 m³ with good vehicle access, drum ready-mix becomes more economical.
A volumetric mixer carries its raw materials in separate compartments: dry cement in a sealed hopper (typically 2–5 tonnes capacity); fine aggregate (sharp sand) and coarse aggregate (gravel or all-in ballast) in separate bins; water in a tank (typically 500–1,500 litres); and admixtures (plasticiser, retarder, accelerator, fibre, etc.) in small tanks. When concrete is required, the operator programs the control system with the required mix design and discharge rate. The ingredients are metered by weight or volume into a horizontal mixing auger, mixed thoroughly, and discharged into the pour through a chute or short hose.
The principal advantages of the volumetric process over drum ready-mix are: concrete is mixed fresh at the point of discharge, eliminating the 2-hour time limit that applies to drum ready-mix; the mix can be adjusted during the pour (different grades or slumps for different parts of the pour); the exact volume required can be delivered without waste; and the smaller vehicle size improves access to restricted sites. The principal disadvantages are: higher per-m³ cost than drum ready-mix for large volumes; the quality of the mix depends more on the skill of the operator and the calibration of the machine; and conformity documentation is less comprehensive than for QSRMC-certified ready-mix plants.

The biggest advantage of volumetric concrete over drum ready-mix is that there is no minimum order quantity. You pay a call-out fee (typically £80–£200) plus a per-m³ rate for exactly the volume discharged. If your foundation takes 0.7 m³, you pay for 0.7 m³ — not for the minimum 3–6 m³ that most ready-mix plants require. The call-out fee means very small pours (under 0.3 m³) are still often cheaper with bagged concrete, but for 0.5–4 m³, volumetric is almost always the best value.
Volumetric concrete is mixed at the point of delivery — not at a plant hours beforehand. This means there is no 2-hour drum-rotation limit (the statutory time limit for drum ready-mix after water is added at the plant). A volumetric truck can sit on your drive all day and mix concrete on demand, allowing unhurried pours without the pressure of a tight discharge window. It also means the mix is genuinely fresh, with no risk of partial hydration or stiffening during transit.
A volumetric mixer can change mix grade between deliveries during the same visit. If you need GEN 0 for a blinding layer and then GEN 3 for a foundation, a single volumetric truck can deliver both by reprogramming the mix proportions between pours — with no additional call-out fee. This flexibility is unique to volumetric concrete and is not possible with drum ready-mix, where a separate truck is needed for each mix grade.
Volumetric trucks are typically narrower and more manoeuvrable than standard drum ready-mix lorries. Most are available as rigid or articulated vehicles of 3.5–18 tonnes GVW — significantly lighter and smaller than a fully loaded drum truck (26–32 tonnes). This enables access to sites with narrow lanes, low-clearance bridges, or weight-restricted roads where a drum truck cannot go. Always confirm the vehicle dimensions and axle weights with the supplier before booking if access is marginal.
Volumetric concrete's per-m³ rate is typically 15–35% higher than equivalent drum ready-mix concrete — approximately £128–£158/m³ for GEN 3 volumetric vs £98–£140/m³ for drum ready-mix in South East England in 2026. This premium reflects the higher operating cost of the volumetric truck (more sophisticated machinery, smaller batch capacity, higher fuel use per m³ delivered). However, once the short-load surcharge and minimum order constraints of drum ready-mix are accounted for, volumetric is often cheaper in total for pours under approximately 4 m³.
Volumetric concrete is regulated under BS EN 206 and must meet the same strength and durability requirements as drum ready-mix. However, the quality assurance regime at volumetric suppliers is generally less comprehensive than at QSRMC or BSI-certified ready-mix plants — calibration of metering systems is critical and less consistently third-party verified. For routine domestic work (foundations, slabs, garden walls), volumetric quality is entirely adequate. For structural concrete subject to Building Regulations or engineering specification, check that the supplier can provide mix design certificates and cube test results, and confirm the supplier's quality accreditation before ordering.
Most drum ready-mix plants charge a short-load surcharge of £100–£200+ for orders below their minimum (typically 3–6 m³). At 1 m³, the total cost of drum ready-mix including short-load surcharge is often £350–£520 — comparable to or more than volumetric concrete for the same volume. Volumetric concrete has no such surcharge: the call-out fee is the equivalent, and at £80–£200, it is generally lower than ready-mix short-load penalties while also buying access to a fully functional concrete mixer and unlimited additional volume.
Many volumetric concrete suppliers offer Saturday delivery as standard, and some offer Sunday or evening delivery at a premium. This is significantly more flexible than drum ready-mix plants, many of which close on Saturdays or charge substantial weekend premiums. For self-builders and DIYers who can only work at weekends, volumetric concrete is often the only practical option for freshly mixed concrete without the expense of a Saturday ready-mix premium.
Volumetric trucks carry admixture tanks and can add plasticisers, retarders, accelerators, fibre reinforcement, and air-entraining agents at the point of mixing on customer request. This on-demand admixture capability is a significant practical advantage — particularly for summer pours requiring a retarder to extend workability, winter pours needing an accelerator, or slabs requiring polypropylene fibres for crack control. Confirm what admixtures are available with your local supplier before booking.
Unlike drum ready-mix trucks that require a designated washout area with proper drainage or a skip to receive drum washout water, volumetric trucks wash out the mixing auger in a much smaller, more controlled quantity of water and cement residue. Most suppliers wash out directly onto soil or gravel at the site — the small quantity of alkaline washout is not a significant environmental concern for domestic sites. No skip hire is required for washout, unlike drum ready-mix.
For phased construction projects where concrete is needed in small quantities over an extended period, volumetric concrete is ideal — a single supplier relationship and call-out fee structure means you can order exactly what you need for each phase without over-ordering. For rural or remote sites far from a ready-mix plant, volumetric trucks can travel further and still deliver mixed fresh concrete without the transit time problems that affect drum ready-mix in hot weather or on long routes.
Volumetric concrete supply is subject to 20% standard rate VAT in most construction contexts — the same as drum ready-mix. For new residential dwellings, concrete supply (whether volumetric or drum) is zero-rated for VAT under HMRC's new build relief — a significant saving on larger projects. Extensions, repairs, and commercial works are always standard-rated. Confirm the applicable VAT rate with your supplier, particularly for new build and self-build projects where the VAT difference can be substantial.

Volumetric concrete (also called mini-mix concrete) is concrete that is mixed at the point of delivery using a specialised lorry that carries dry cement, separate aggregates, water, and admixtures in individual compartments. The ingredients are metered and mixed on-board as the concrete is discharged. Standard drum ready-mix concrete is batched and mixed at a central plant, loaded into a rotating drum truck, and delivered to site — where it must be discharged within 2 hours of water being added at the plant. The key practical differences are: volumetric has no minimum order and you pay only for what is discharged; volumetric concrete is freshly mixed with no transit time limit; and volumetric trucks are typically smaller and better suited to restricted-access sites. The trade-off is that volumetric concrete costs 15–35% more per m³ than drum ready-mix for equivalent grades.
Volumetric (mini-mix) concrete costs approximately £115–£200 per m³ depending on mix grade and region in 2026, plus a call-out / mobilisation fee of approximately £80–£200 per visit. For the most common domestic mix — GEN 3 / ST4 — expect to pay approximately £128–£158/m³ in South East England, giving a total cost of approximately £228–£318 for 1 m³ (including call-out fee). In North England, Wales, and Scotland, deduct approximately 10%. In Greater London, add approximately 15–20%. The per-m³ rate is higher than drum ready-mix (£98–£140/m³ for GEN 3) but the elimination of short-load surcharges means volumetric is often cheaper in total for pours under 3–4 m³.
There is no minimum order for volumetric concrete — you pay a call-out fee (typically £80–£200) and then a per-m³ rate for exactly the volume discharged. If your pour only uses 0.6 m³, that is exactly what you pay for. This is the primary commercial advantage of volumetric over drum ready-mix, where minimum orders of 3–6 m³ are typical and short-load surcharges of £100–£200+ apply for smaller volumes. The call-out fee structure means that very small volumes (under approximately 0.2–0.3 m³) may still be cheaper using bagged concrete mixed on site, but for pours of 0.5 m³ and above, volumetric is almost always more economical than bagged concrete and more flexible than drum ready-mix.
Volumetric concrete is the best choice in these situations: when your pour volume is between 0.3 and 4 m³ (the sweet spot where volumetric beats both bagged and ready-mix); when vehicle access is restricted and a full-size drum truck cannot reach the pour point; when you need flexibility on volume (you can stop the pour at any point and pay only for what was discharged); when you want to pour multiple mix grades in one visit without multiple truck visits; when you need concrete on a weekend or Saturday when ready-mix plants may be closed or expensive; and when the pour point is far from a ready-mix plant and transit time would compromise drum concrete quality in hot weather.
Volumetric concrete can produce concrete of equivalent strength and quality to drum ready-mix when the machine is properly calibrated and operated by an experienced driver. Volumetric concrete must conform to BS EN 206 and is subject to the same standard specifications as drum ready-mix. However, the quality assurance regime at volumetric suppliers is generally less comprehensive than at QSRMC-certified ready-mix plants — third-party verification of metering accuracy is less consistent, and mix design documentation may be less detailed. For routine domestic work (foundations, slabs, garden walls), volumetric quality is entirely adequate. For structural concrete subject to Building Regulations or engineering specification, verify that your volumetric supplier can provide mix design documentation, water/cement ratio confirmation, and cube test results, and check their quality certification before ordering.
Volumetric concrete suppliers are widely available across the UK in 2026. The most effective ways to find a local supplier are: search online for "mini-mix concrete" or "volumetric concrete" followed by your town or postcode; ask your builder, groundworker, or landscaper for their preferred supplier; check Checkatrade or TrustATrader for concrete suppliers in your area; or contact your local builders' merchant who will usually have supplier recommendations. When requesting a quote, provide: the approximate volume required; the mix grade needed; your postcode; and any access restrictions. Ask specifically whether the quote includes the call-out fee and VAT, and what additional charges apply for weekend delivery, admixtures, or difficult access.
Yes — volumetric concrete can be used for domestic strip foundations, pad foundations, and ground floor slabs requiring compliance with Building Regulations. For standard domestic applications, specifying GEN 3 (equivalent to C25) from a reputable volumetric supplier is straightforward and widely accepted by building inspectors. For larger or more complex structural applications — reinforced concrete beams, columns, or basement walls under engineering design — confirm with your structural engineer that volumetric supply is acceptable, and verify that the supplier can provide adequate QA documentation (mix design certificate, water/cement ratio, and cube test results to confirm conformity). Some structural engineers and building control officers prefer QSRMC-certified drum ready-mix for structural applications; discuss this with your professional team before committing to volumetric supply on complex projects.
A volumetric concrete truck can typically discharge at a rate of approximately 0.5–1.5 m³ per minute depending on the consistency specified and the distance from the truck to the pour point. For a typical domestic pour of 1–2 m³, the actual concrete delivery time is approximately 5–15 minutes from the start of discharge. However, the total site time — including arrival, set-up, pour, and washout — is typically 30–60 minutes for a small domestic pour. Unlike drum ready-mix, there is no pressure to discharge quickly: the volumetric truck can mix at whatever rate the placing crew needs, pausing between sections of the pour if required.
A call-out fee (also called a mobilisation fee or visit charge) is the fixed charge made by a volumetric concrete supplier for each visit to your site, regardless of the volume of concrete delivered. It covers the cost of the driver's time, vehicle fuel, and operating costs for the journey to your site and back. In 2026, UK call-out fees range from approximately £80–£200 depending on the supplier and distance from their base. When comparing volumetric quotes, always confirm whether the quoted price is the per-m³ rate alone or includes the call-out fee — quotes given as an all-in price per m³ for a specified volume are easier to compare. Note that if you order a second delivery in the same day for a top-up pour, most suppliers will charge a second call-out fee.
Yes — volumetric concrete requires exactly the same curing regime as equivalent drum ready-mix concrete. Curing (maintaining adequate moisture and temperature in the fresh concrete while it gains strength) is not a function of how the concrete was supplied but of the concrete's constituent materials and the curing conditions. For standard GEN 3 / C25 concrete in typical UK conditions (15–20°C), maintain moisture for a minimum of 3–5 days by covering with polythene sheeting, wet hessian, or a curing compound applied to the surface. In cold weather (below 5°C), extend curing and protect from freezing. In hot or windy weather, begin curing as soon as the bleed water has disappeared from the surface — earlier than in cooler, still conditions.
Yes — this is one of the most useful features of volumetric concrete. A single volumetric truck can deliver multiple mix grades during the same visit by reprogramming the mix proportions between pours, with no additional call-out charge. For example, you can order GEN 0 for a 50mm blinding layer, then immediately follow with GEN 3 for the main foundation pour from the same truck. Or you can start a foundation in GEN 3 and finish it in a slightly wetter consistency for the last pour without difficulty. This flexibility is impossible with drum ready-mix, where a separate truck and delivery charge are required for each different mix grade. It is particularly valuable for projects with multiple concrete specifications (blinding + foundation + slab) that can all be combined into a single volumetric visit.
