Free Ready-Mix Volume, Mix Quantities & Cost Estimator – Updated 2026 NI Prices
Whether you are pouring foundations for a detached house extension in Belfast, a new shed base in Ballymena, a reinforced driveway in Derry, or an industrial hardstanding at a manufacturing facility in the Antrim economic corridor, our Northern Ireland concrete calculators give you accurate volume estimates, ready-mix order quantities, and updated 2026 Northern Ireland concrete prices from local suppliers. Northern Ireland consistently records the lowest ready-mix concrete prices in the United Kingdom, typically running 12–18% below South East England prices and 5–10% below the North of England and Scotland. This price advantage reflects Northern Ireland's abundant local aggregate resources, relatively lower operating costs, and a well-developed network of local ready-mix producers that keeps inter-supplier competition strong across the province.
Northern Ireland's construction market in 2026 is active across all sectors. Belfast continues to attract major investment, with ongoing residential development at Titanic Quarter, commercial expansion around the City Quays and Weavers Cross transport hub, significant student accommodation construction around Queen's University and Ulster University, and major public sector investment including the new Royal Victoria Hospital developments. Outside Belfast, the regional towns of Derry/Londonderry, Ballymena, Antrim, and Newry all have active construction markets, while the rural economy generates steady demand for agricultural and farm concrete across Antrim, Down, Tyrone, Fermanagh, and Armagh.
In 2026, ready-mix concrete prices in Northern Ireland range from approximately £80–£118 per m³ for standard grades (C20/25 through C30/37) — the lowest range of any UK region covered in this series of calculators. Our calculator uses Northern Ireland-specific pricing benchmarks adjusted for your area to give you an accurate estimate before you contact local suppliers.
Northern Ireland operates its own distinct building control system, separate from both the English and Welsh Building Regulations and the Scottish Building Standards. In Northern Ireland, building control is governed by the Building Regulations (Northern Ireland) 2012 (and subsequent amendments), administered by the relevant district council building control department or by approved inspectors registered with the Building Control Northern Ireland (BCNI) scheme. The principal differences from the English system that affect concrete work are:
Northern Ireland has a well-developed ready-mix concrete industry with both national operators and strong local producers serving the province. The main suppliers in 2026 include:

Northern Ireland records the lowest ready-mix concrete prices in the UK. In 2026, C20/25 costs approximately £82–£106/m³ — approximately 12–18% below South East England, and 5–8% below North England. C25/30 is approximately £88–£114/m³.
Northern Ireland sits on the Antrim Basalt Plateau — one of the UK's richest aggregate resources. This abundant, high-quality crushed basalt is the primary aggregate in NI ready-mix concrete, and its proximity to Belfast and east NI eliminates long haulage costs that inflate prices in aggregate-scarce regions.
Northern Ireland uses the Building Regulations (Northern Ireland) 2012 with Technical Booklets (not English Approved Documents). Building control is administered by district council building control departments. Always check the current NI Technical Booklets for the correct standards.
All Northern Ireland postcodes begin with BT — the only UK region with a single postcode prefix covering the entire province. BT1–BT5 cover central Belfast; BT47–BT48 cover Derry; BT71–BT82 cover the west (Tyrone and Fermanagh).
Northern Ireland has a very large agricultural sector relative to its population. Farm hardstandings, silage bases, slurry stores, and dairy wash-down areas generate major ready-mix demand across counties Antrim, Down, Armagh, Tyrone, and Fermanagh. Agricultural SRPC mixes are a standard product line for all NI suppliers.
Central Belfast and low-lying areas near Belfast Lough are underlain by soft estuarine alluvial clays. These can be weak and compressible, requiring deeper foundations than the Technical Booklet D simplified rules. Ground investigation is recommended for any significant building project in low-lying Belfast.
Significant areas of deep peat and bogland across County Fermanagh, west Tyrone, and parts of Armagh are completely unsuitable for standard strip foundations. Any construction in these areas requires ground investigation and specialist foundation design — raft or piled foundations are common.
Belfast's Titanic Quarter — built on former Harland and Wolff shipyard land — is among the UK's largest urban regeneration zones. Ground conditions include made ground, former industrial infrastructure, and tidal alluvium requiring specialist foundations. Active development continues with offices, hotels, and residential buildings through 2026.
Northern Ireland has no Clean Air Zone or ULEZ charging scheme in 2026. Concrete delivery vehicles across the province are not subject to any clean air charge — a cost advantage compared to London, Bristol, and Birmingham.
Construction near the Republic of Ireland border (south Armagh, south Down, Fermanagh, Tyrone) can involve cross-border logistics. Ready-mix from NI plants is the norm for border area projects — Irish Republic concrete prices are set in Euros and typically slightly higher than NI prices due to higher VAT (13.5% ROI vs 20% NI/UK).
Northern Ireland's Atlantic climate brings cold and wet conditions from October to April. Temperatures below 5°C are common, making cold weather concreting precautions (accelerator admixtures, frost blankets, warm water) a routine requirement from autumn through spring.
NI ready-mix suppliers typically apply a short-load surcharge of £40–£130 for orders under 4 m³ — generally slightly lower than equivalent GB surcharges, reflecting lower NI operating costs. Many small domestic NI pours (under 2 m³) still trigger this surcharge.
For small pours under approximately 1 m³ where ready-mix short-load surcharges make delivery uneconomical, site-mixing using basalt ballast and cement from Northern Ireland builders' merchants provides a practical alternative. The table below gives material quantities and estimated 2026 NI costs per m³ for the most common mixes.
| Mix | Equiv. Grade | Cement / m³ | Ballast / m³ | Water / m³ | Cement Bags (25kg) | Est. Materials Cost / m³ (NI 2026) |
|---|---|---|---|---|---|---|
| GEN 1 (1:3:6) | C8/10 | ~220 kg | ~1,920 kg | ~110 L | ~9 bags | ~£148 |
| GEN 3 (1:2:4) | C20/25 | ~310 kg | ~1,750 kg | ~170 L | ~13 bags | ~£179 |
| RC25 (1:1.5:3) | C25/30 | ~370 kg | ~1,650 kg | ~185 L | ~15 bags | ~£196 |
| RC30 (1:1:2) | C30/37 | ~480 kg | ~1,500 kg | ~215 L | ~19 bags | ~£220 |
Costs based on NI 2026 merchant prices: CEM I 42.5 N at £7.80/25kg bag (NI cement prices are slightly below GB levels); crushed basalt all-in ballast at £38/tonne delivered. NI basalt aggregate produces concrete with excellent compressive strength and durability characteristics. Note that basalt ballast produces a stiffer, darker-coloured mix than limestone or gravel-based concrete — this is normal and does not indicate any quality issue.

Northern Ireland has the lowest ready-mix concrete prices in the UK. In 2026, C20/25 (GEN 3) costs approximately £82–£106/m³ and C25/30 (RC25) approximately £88–£114/m³ — approximately 12–18% below South East England prices and 5–8% below North England equivalents. These prices are for weekday deliveries of 4 m³ or more. For orders under 4 m³, a short-load surcharge of £40–£130 applies. Northern Ireland's low prices reflect abundant local basalt and limestone aggregate resources, lower operating costs, and strong competition from local and family-owned concrete producers.
Northern Ireland operates its own building control system under the Building Regulations (Northern Ireland) 2012, which is separate from England's Building Regulations 2010. Applications are made to your local district council building control department — not to a generic Building Control Body as in England. The technical standards are set out in Northern Ireland Technical Booklets (published by the Department of Finance NI) rather than English Approved Documents, though the technical content is broadly similar. Key NI-specific differences include slightly different flood risk assessment requirements, some different fire safety prescriptions, and NI-specific provisions relating to ground conditions and subsoil drainage. The Building Control (Amendment) Regulations (Northern Ireland) 2023 introduced enhanced inspection requirements for certain complex buildings. For standard domestic concrete work, the process is essentially: submit application → receive approval or acknowledgment → notify building control before key stages → arrange inspection → receive completion certificate.
Northern Ireland's consistently lower concrete prices result from several structural factors: abundant local aggregate — the Antrim Basalt Plateau provides high-quality crushed basalt within short haulage distances of the main population centres, eliminating the long-distance aggregate transport costs that inflate prices in southern England; lower labour and operating costs — NI wages and business operating costs are generally lower than England, particularly compared to London and the South East; strong local competition — Northern Ireland has a high proportion of well-established local and family-owned ready-mix operators alongside national chains, maintaining competitive tension in the market; and no clean air zone charges — NI delivery vehicles face none of the ULEZ or CAZ charges that add to concrete delivery costs in London, Bristol, and Birmingham.
The main ready-mix concrete suppliers serving Northern Ireland in 2026 are Breedon Group (with a strong NI presence including former local NI businesses), Tarmac / CRH (CRH plc is Irish-headquartered with long-established NI operations), and Hanson UK. Local NI operators including Creagh Concrete, Quinn Building Products, and Acheson and Glover are important regional players and often offer the most competitive pricing for domestic and agricultural projects. Jewson and Travis Perkins have NI branches for site-mix materials. For specialist mixes (GGBS, SRPC agricultural, rapid-hardening winter mixes), check availability with your specific supplier as not all NI plants produce the full range.
For farm hardstandings, yard surfaces, and feed passages in Northern Ireland, the recommended specification is C25/30 with sulphate-resisting Portland cement (SRPC) or a high GGBS blend (40–50% GGBS replacement). Agricultural concrete is exposed to an extremely aggressive chemical environment — livestock slurry and silage effluent are highly acidic and contain organic acids and sulphates that attack standard OPC concrete. For silage bases and silos, the specific requirements of the Water Resources (Northern Ireland) Order 1999 and the Silage, Slurry and Agricultural Fuel Oil (SSAFO) Regulations (Northern Ireland) must be met — these specify minimum slab thickness, impermeable construction, and drainage requirements to prevent pollution of watercourses and groundwater. Consult the DAERA (Department of Agriculture, Environment and Rural Affairs NI) for current requirements before specifying agricultural concrete in Northern Ireland.
Belfast sits in a river valley at the mouth of Belfast Lough, and much of the city — particularly the central and northern areas — is built on soft estuarine alluvial clays and silts laid down when the Lough extended further inland. These clays can be soft, compressible, and sensitive to disturbance, meaning that standard strip foundations from the Technical Booklet D simplified rules may be inadequate on many central Belfast sites. The former Harland and Wolff shipyard area (now Titanic Quarter) and adjacent former industrial lands along the Lagan and the Lough shore have additional complications from made ground, buried industrial structures, and contaminated land. In contrast, the southern Belfast suburbs (Malone, Stranmillis) and the Lagan Valley are underlain by gravel river terraces providing better foundation conditions. Ground investigation is always recommended in Belfast, particularly for any project in low-lying areas or on former industrial land.
Yes — any structural concrete work forming part of a building in Northern Ireland requires a Building Regulation Application to the relevant district council building control department. In Belfast, this is Belfast City Council Building Control; in Derry / Londonderry, it is Derry City and Strabane District Council; in Antrim and Newtownabbey, it is Antrim and Newtownabbey Borough Council Building Control — and so on for each of Northern Ireland's 11 district councils. The building control inspector must be notified before foundation concrete is poured and must inspect the excavation at the appropriate stage. Retain all ready-mix delivery tickets confirming the concrete grade and BS EN 206 conformance for the building control file. Do not cover foundations without building control inspection sign-off.
Yes — deep peat is a significant ground condition risk across substantial areas of Northern Ireland, particularly in County Fermanagh (around Lough Erne), west County Tyrone, parts of County Armagh, and the Antrim uplands. Peat is highly compressible and provides virtually no bearing capacity for conventional strip or trench fill foundations — attempting to pour standard domestic foundations onto peat will result in differential settlement and structural damage to the building. Any project on suspected peat ground requires: a professional ground investigation to confirm the presence and depth of peat; a structural engineer's foundation design appropriate for the conditions — typically raft foundations, ground improvement, or piled foundations extending through the peat to the firm stratum beneath; and Building Regulation approval confirming the design is adequate. Do not attempt to pour concrete foundations on peat ground without specialist engineering advice.
For external concrete within approximately 1 mile of the North Atlantic coast or the major sea loughs (Belfast Lough, Strangford Lough, Lough Foyle, Carlingford Lough), a frost-resistant and chloride-resistant specification is required. For external slabs, paths, and drives, specify C28/35 with air-entraining admixture (PAV1 or PAV2 under BS 8500) to resist freeze/thaw damage and sea spray chloride penetration. For structures directly at the coast — sea walls, harbour walls, slipways — specify C32/40 with 50% GGBS replacement, maximum water:cement ratio of 0.40, and XS2–XS3 exposure class concrete per BS 8500, with appropriate reinforcement cover (50–60mm nominal). The Giant's Causeway area, Causeway Coast, and exposed North Antrim cliffs represent the most severe marine exposure environment in Northern Ireland.
For construction projects near or straddling the Northern Ireland / Republic of Ireland border — in south Armagh, south Down, Fermanagh, and Tyrone — there are several practical considerations. Building regulations: the NI Building Regulations apply to any building in Northern Ireland, and the ROI Building Regulations (enacted by the BCMS/SEAI system) apply to buildings in the Republic — two entirely different regulatory systems. Concrete supply: it is generally more practical to source ready-mix from a Northern Ireland plant for NI-side work and from a Republic plant for ROI-side work, avoiding currency exchange complications and different VAT systems (NI: 20% UK VAT; ROI: 13.5% ROI VAT on construction materials). There is no tariff or physical border control on goods or vehicles crossing the Ireland / Northern Ireland border under the post-Brexit Windsor Framework, so cross-border concrete deliveries are logistics-practical — it is simply the commercial, tax, and regulatory considerations that make using a plant on the same side of the border the more straightforward choice.
Most Northern Ireland ready-mix suppliers have a minimum order of 1.0 m³, with short-load surcharges of £40–£130 applying for orders below their standard minimum load (typically 4–6 m³). NI short-load surcharges are generally slightly lower than equivalent GB surcharges, reflecting NI's lower operating costs. For pours of 0.75 m³ or less, site-mixing from an NI builders' merchant using NI-sourced basalt ballast is often more economical. The crossover point where ready-mix becomes more economical than site-mixing (even with the surcharge) is typically around 0.75–1.0 m³ in Northern Ireland. Local independent NI operators sometimes offer more flexible minimum orders than national chains — worth calling a local plant directly for small domestic pours.
Northern Ireland's Atlantic maritime climate — with cool, wet winters and temperatures regularly below 5°C from October to April — means that cold weather concreting precautions are a routine seasonal requirement for most of the year. Standard CEM I 42.5 N concrete hydrates very slowly below 5°C and can be permanently damaged if frozen before achieving adequate early strength. When temperatures are forecast below 2°C within 24 hours of a planned pour: specify a rapid-hardening mix (CEM I 42.5 R) or request an accelerator admixture from your NI supplier (typically £5–£8/m³ additional); use warm mixing water; immediately cover the fresh concrete with insulating frost blankets or polythene; avoid pouring onto frozen ground; and extend the curing protection period beyond the standard 3–7 days. All major NI ready-mix suppliers offer rapid-hardening and accelerated winter mixes as a routine product, reflecting how frequently they are needed across the province's construction season.
