Bricklayers & Groundworkers: running the business side
Running a bricklaying and groundwork business in the UK presents unique business challenges. The demand for intricate brickwork, alongside large scale groundwork projects, requires both precision and efficiency. Pricing can be tricky, as you're often dealing with variables like weather conditions and site accessibility. Groundworkers need a solid grasp of plant machinery costs, while bricklayers must perfect their per-thousand brick pricing. Cash flow can become tight due to lengthy payment terms typical in larger contracts. Effective management of labour, equipment hire, and material costs will determine your profit margins. Staying on top of these elements can mean the difference between a profitable project or a financial headache.

Cost structure
What this trade has to recover
Miss any of these in your rate and the shortfall comes out of your own wages.
- Labour Costs
- Bricklayers and groundworkers generally work in gangs, requiring payment for multiple team members. Labour costs can quickly escalate if there's an unexpected delay or if additional manpower is needed. Calculating the true hourly rate for each worker, including any on-costs like National Insurance contributions, is crucial for precise pricing.
- Materials
- The cost of materials such as bricks, concrete, stone, and aggregates can fluctuate based on market conditions. It's vital to keep an eye on these prices regularly, ordering in advance during stable pricing periods. Adding a markup of 10-15% on materials helps cover the risk of wastage or unexpected price spikes.
- Plant and Equipment Hire
- Heavy machinery like excavators and dumpers can be costly to hire. Ensure your pricing strategy covers not just the hire but also fuel, delivery, and potential downtime costs. Negotiating longer-term rental agreements might reduce short-term hire costs.
- Muck Away Services
- Disposing of spoil and waste materials often requires hiring grab lorries or skips. The cost can vary significantly depending on the volume and frequency of services required. Incorporating a 10% contingency into your pricing helps cover unexpected muck away needs.
- Insurance
- Public liability and employer’s liability insurance are essential for protecting your operations. Premiums can be a significant outlay, influenced by the nature of your projects, the size of your team, and your claims history. Annual review and competitive quotes help manage these costs.
- Transport and Fuel
- Fuel costs for moving between jobs, as well as running machinery on-site, can add up. With the ongoing fluctuations in fuel prices, it’s wise to include a cushion in your budget. A fleet fuel card can help track and manage these expenses efficiently.
- Standing-time Allowances
- Unexpected delays, whether due to weather or client indecision, can halt progress. Allocating around 5% of your total labour costs as a standing-time allowance can safeguard against such eventualities without heavily impacting your bottom line.
- Site Overheads
- Site establishment costs such as temporary site offices, toilet facilities, and security contribute to your overall project cost. These are typically proportionate to the scale and duration of the job, but should always feature in your initial project pricing.
- Tool and Equipment Maintenance
- Regular maintenance of tools and smaller plant equipment is essential to avoid downtime. This involves replacement parts, servicing, and eventual replacement of aged equipment. Budgeting for this recurring expense helps maintain smooth project progression.
- Professional Services
- Engaging architects, engineers, or surveyors for more complex groundwork and bricklaying projects incurs additional costs. These services need to be factored into your pricing from the outset to prevent surprise deductions from your profit margin.
How the money normally arrives
- Payment upon completion: Common in smaller domestic projects, this pattern leaves tradespeople covering upfront costs but simplifies financial management upon receipt.
- Staged payments: For larger projects, securing payments at key phases (e.g., foundation, walls, roofline complete) maintains cash flow and reduces risk.
- Retention clauses: Common in commercial contracts, they withhold 5-10% of payment pending satisfactory project sign-off, affecting cash availability.
- Late payment norms: Especially in real estate markets, 30-60 day terms are typical. Being prepared for these delays helps manage cash flow expectations.
- Deposits for materials: Requesting a portion of the project cost upfront to cover material purchase reduces the initial financial burden.
- End-of-month billing: Some clients prefer monthly invoices to align with their financial accounting; this regularity aids in predicting cash flow.
- Direct bank transfers: Fast and efficient, reducing administrative tasks. Ensures prompt payment once work is signed off.
- Retention release periods: Usually six months to a year post-completion, requiring forward planning to ensure cash flow isn’t disproportionately affected.
- Final account settlement: The last portion of payment upon job completion, commonly requiring follow-up and negotiations to settle.
Where the margin leaks
- Weather delays: Bad weather can halt outdoor work, squeezing timelines and cash flow when labour is already committed.
- Plant hire overruns: If projects overrun, extra plant hire days quickly eat into the profit margin unless terms are carefully managed.
- Material cost increases: Sudden increases in raw material prices can slash profits unless a buffer is built into the pricing.
- Labour shortages: In an ongoing skills shortage, failure to secure skilled bricklayers or groundworkers can delay projects and incur additional costs.
- Payment delays: Especially in commercial work, payment can be slow, requiring robust management to prevent cash flow problems.
- Costly rework: Mistakes in brickwork or groundwork can be expensive to rectify, emphasising the importance of initial precision.
- Client changes: Alterations in project specifications mid-way can lead to increased costs and extended deadlines if not managed contractually.
- Safety incidents: Accidents on sites can halt operations and incur insurance costs, affecting project timelines and financial stability.
- Project disputes: Disagreements over quality or timelines can delay final payment and strain cash resources, highlighting the necessity for clear contracts.
Worked example
Extension Substructure Priced with Plant and Muck Away
- Gang labour: 3 people, 6 days = 144 hours
- True hourly rate needed per person: £38
- Labour recovery: 144 × £38 = £5,472
- Concrete, blocks, and stone at cost: £3,400, at 12% markup = £3,808
- Excavator and dumper hire: £980 plus 10% = £1,078
- Muck away, 6 grab loads: £1,320 plus 10% = £1,452
- Standing-time allowance at 5% of labour: £274
Quote £12,084 plus VAT if registered, and ensure you hold enough cash to cover four to six weeks before the first payment.
