Bills of Quantities (BOQ)
A Bill of Quantities is a detailed list of every material and task required to complete your project. Our BOQs follow NRM and SMM7 standards. These are industry-recognised measurement rules that support tendering and procurement. A well-prepared BOQ allows contractors to price work accurately and consistently. It also forms the basis for contract administration, interim valuations, and final account settlement. We deliver in Excel and PDF formats with trade-specific breakdowns. Each BOQ includes quantity take-offs, unit rates, and detailed descriptions that comply with RICS standards.
- NRM & SMM7 compliant BOQs
- Excel & PDF formats
- Procurement-ready documentation
Tendering & Bid Support
We help contractors submit competitive and accurate tenders. Tendering is one of the most critical stages in winning construction work. An accurate tender price protects profit margins while remaining competitive enough to win the job. Our services include tender analysis, subcontractor comparisons, cost risk review, and bid optimisation support. We review tender documents for ambiguities, assess the completeness of pricing, and identify areas where costs can be reduced without compromising quality. For developers, we provide independent tender evaluation to ensure received prices represent fair market value.
- Tender analysis
- Subcontractor comparisons
- Bid optimisation support
Cost Reporting
Detailed financial reporting throughout the construction lifecycle. Cost reporting ensures that project finances remain visible and controlled from start to finish. This covers interim valuations through to final account. Interim valuations establish the value of work completed at each stage, forming the basis for monthly payments. Cash flow forecasting predicts when costs will arise, helping clients plan their funding. Final account reporting reconciles all costs against the original budget, identifying variations and ensuring every pound is accounted for. You keep full control of project spend at every stage.
- Interim valuations
- Cash flow forecasting
- Final account reporting
Eco Works & CESP
CESP services and eco-building works to help clients meet sustainability and regulatory requirements. The construction industry is under increasing pressure to reduce carbon emissions and improve energy efficiency. We provide practical, cost-effective solutions that meet regulatory standards without inflating budgets unnecessarily. Our CESP (Carbon Emission Savings Programme) services help public sector and commercial clients achieve their carbon reduction targets. We also advise on eco-friendly building materials, insulation upgrades, and renewable energy integration. All recommendations are grounded in realistic cost analysis so sustainability goals remain financially viable.
- CESP services
- Eco-building works
- EPC compliance support
How It Works
How does the construction estimating process work?
The estimating and cost planning process is designed to be direct. Clients submit drawings or a brief, receive a detailed cost forecast typically within 24 hours, and review the output with the surveyor. The practice combines traditional quantity surveying methods with modern estimating software. Cost forecasts are based on cost data updated daily for the most accurate estimates.
01
Submit Your Drawings
Send us your architectural drawings, plans, or project brief by email or through our contact form. We work with projects of every size. This includes single-room extensions and multi-million pound commercial developments.
- Drawings, PDFs, or project brief
- Any stage — concept to planning
- Residential, commercial & industrial
02
Receive Your Estimate
We analyse your project and produce a detailed cost estimate. Most estimates are ready within 24 hours. A cost estimate shows what your project will cost before work begins. It breaks costs down by trade and by building element. We use cost data that is updated daily to produce the most accurate estimates.
- Turnaround within 24 hours
- Daily updated cost data
- Full trade-by-trade breakdown
03
Review & Refine
We walk you through the estimate on a call. If your scope changes, we revise the document quickly. A Bill of Quantities turns your estimate into a detailed list of every item of work. Contractors use this for pricing and contract administration. You receive a final document ready to send to contractors.
- Plain-English review call
- Revisions included as standard
- Contractor-ready documentation
Behind the Numbers
How We Source Our Cost Data
Accuracy starts with the data. We combine live market feeds, daily refreshed supplier pricing, UK regional cost indices, and four decades of project history to produce estimates you can trust.
Real-time feeds
Live Market Monitoring
We monitor pricing from major UK building material suppliers, merchant databases, and trade-specific cost indices every day. This includes timber, steel, concrete, insulation, and M&E components. Our monitoring covers national suppliers such as Travis Perkins, Jewson, and Wickes, as well as specialist merchants for roofing, electrical, and plumbing materials. By tracking live price movements across the entire supply chain, we ensure our estimates reflect current market conditions rather than outdated published rates.
Updated every 24hrs
Daily Data Refresh
Our estimating software pulls updated rates every morning before any estimate is produced. If a material price moves overnight — for example, if timber costs increase due to supply chain disruption or steel prices fluctuate with global demand — that change is reflected in your cost forecast the same day. This daily refresh cycle is what separates our estimates from those based on static price books that may be months out of date.
Location accurate
UK Regional Adjustments
Construction costs vary significantly between London, Birmingham, Manchester, and rural areas. London and the South East typically command 15–25% premiums over Midlands and Northern rates due to higher labour costs, transport expenses, and site access constraints. We apply location-specific adjustment factors derived from BCIS indices and our own project database so your estimate reflects true local market rates rather than national averages that can be misleading.
38+ years history
Project Validation
Every estimate is cross-referenced against our database of recently completed projects before delivery. With 38+ years of historical cost data spanning residential extensions, commercial developments, public sector refurbishments, and infrastructure schemes, we spot discrepancies and fine-tune forecasts. If a calculated rate deviates significantly from comparable recent projects, we investigate the cause — whether it is a specification difference, a regional variation, or a market anomaly — and adjust accordingly.

Why Your Building Cost Estimate Is Probably Wrong
A 40-year quantity surveyor explains the three most common ways estimates fail — and what a proper cost plan should actually include.

Budget Range
15–30 m²
Typical Size
10–16 weeks
Build Time
A single storey rear or side extension is the most popular home improvement in the UK. Typically used to create an open-plan kitchen-diner, utility room, or additional living space. Costs vary significantly based on size, specification, and location.
Also budget for:
- Planning & building regs fees (approx. £1,200–£2,500)
- Architect / designer fees (approx. £1,500–£4,000)
- Structural engineer (approx. £500–£1,500)
- VAT at 20% on most works

Who We Work With
Who do we work with?
The practice works with contractors, private homeowners, property developers, architects, engineers, and public sector organisations across the UK. The desk-based approach allows support for projects of any size and complexity, anywhere in the United Kingdom. Services are tailored to the specific requirements of each client type. We also serve subcontractors seeking tender support, investors requiring feasibility analysis, and public sector bodies managing capital programmes. Whether you are a sole trader building a single extension or a national developer planning a housing estate, our estimating and quantity surveying services scale to match your needs.
Main Contractors
Accurate tender pricing and Bills of Quantities to help main contractors win work and manage costs throughout the project lifecycle. Main contractors face intense pressure to price work competitively while protecting profit margins. Our detailed estimates and BOQs give contractors the confidence to submit tenders knowing every cost element has been accounted for. We also provide ongoing cost management during construction, including interim valuations and cash flow forecasting, so contractors maintain financial control from first dig to final handover.
Property Developers
From feasibility budgets to full cost plans — we help developers understand and control costs at every stage of residential and commercial development. Developers need accurate cost information before committing to land purchases or financing. Our feasibility studies provide the early numbers that shape investment decisions. As projects progress, we produce detailed cost plans and cash flow forecasts that help developers manage drawdowns and monitor profitability. At completion, our final account services ensure every variation and additional cost is properly documented and agreed.
Architects
Cost planning support at design stage to ensure projects remain within budget. We work alongside architects to provide reliable cost information from concept to completion. Architects frequently need cost feedback during the design development phase to ensure creative visions align with client budgets. We provide elemental cost plans that break projects down by building element — substructure, superstructure, finishes, services — allowing architects to see where costs are concentrated and identify savings opportunities without compromising design intent.
