Brick and block laying projects can range from a garden wall to a full house extension, and knowing what to expect helps you budget, plan, and hire the right tradesperson. Whether you're comparing quotes or just figuring out if you need a professional, these answers cover the practical details that matter most. Read on to get clarity on costs, timelines, and what separates quality work from cut corners.
How Much Does Block Laying Cost?
Pricing varies significantly by region, project complexity, and material choice. In the UK, expect to pay between £80–£150 per day for a skilled bricklayer, or £40–£60 per square metre of rendered blockwork, depending on whether the wall is single-skin, cavity, or decorative. Specialist work—like Flemish Bond patterns, curved brickwork, or restoration of listed buildings—costs more. Add 15–20% if you're supplying your own materials versus the tradesperson sourcing them.
For a rough estimate: a single-storey brick extension might run £8,000–£15,000 in labour alone, while a simple garden wall of 10 square metres could be £400–£600. Always ask for a fixed quote rather than a day rate to avoid surprises.
What's the Difference Between Brick and Block?
Bricks are smaller, denser, and typically used as a facing material or in visible areas because of their uniform appearance and colour range. Blocks (usually concrete) are larger, faster to lay, and more commonly used for internal walls, foundations, or where they'll be covered with render or plaster.
Brick is more labour-intensive to lay because each unit is smaller, so jobs take longer but look finished immediately. Blocks allow faster progress but usually need covering. Your choice depends on the building's design, your budget, and whether you want the exposed masonry aesthetic.
How Long Does a Project Take?
A skilled bricklayer covers roughly 300–500 bricks or 60–100 blocks per day, depending on the mortar mix, weather, and complexity. A simple cavity wall for a single-storey extension (1,000–1,500 square metres of wall area) typically takes 4–6 weeks, including drying time between lifts.
Weather matters. Frost, heavy rain, and high winds all slow progress. Winter projects take longer than summer ones. Always factor in at least 2–3 weeks for mortar to cure before applying any finishes.
What Should You Look for in a Tradesperson?
The best brick and block layers show:
- Verifiable experience: Ask for references from recent similar projects, not just testimonials
- Insurance and qualifications: Public liability and CSCS card (Construction Skills Certification Scheme)
- Clear written quotes: Breakdown of labour, materials, scaffolding, waste removal, and timelines
- Portfolio photos: Proper mortar joints, consistent colour matching, square corners, and clean pointing
- Site management: How they'll protect existing structures, manage waste, and maintain safety
- Warranty terms: What happens if cracks appear within 12 months?
Don't hire on price alone. A quote 30% lower than others is often a red flag—it may mean shortcuts on mortar quality, rushed work, or hidden costs later.
When Do You Need Planning Permission?
Most brick and blockwork is covered under Building Regulations rather than Planning Permission, but the rules vary by project type and location. A garden wall under 1 metre is usually exempt; one over 2 metres in a conservation area or near a listed building may need Planning Permission.
Any structural wall inside your home—like converting a room—absolutely needs Building Control approval. Your local council's website has the specifics, or ask a surveyor before hiring a bricklayer to avoid costly delays.
What Preparation Is Needed?
The site must be level and compacted. For new builds, foundations should already be poured and checked. For extensions, the existing wall needs cleaning and any old mortar chasing out if you're tying new work in.
Materials should be delivered and stacked on-site a few days early so the bricklayer isn't waiting. You'll also need proper scaffolding (typically £2–4 per square metre per week for hire), which adds to the timeline and cost.
Can You Compare Quotes Easily?
Yes, but only if you're comparing like with like. Ensure all quotes cover the same scope: is scaffolding included? Who supplies materials? What's the finish specification? Platforms like Mercoly let you find and compare trusted brick and block laying providers in one place, making it easier to spot fair pricing and genuine expertise.
Frequently Asked Questions
Q: What's the best mortar mix for brickwork? A: Standard 4:1 (sand to cement) is typical for general brickwork; softer mixes (5:1 or 6:1) suit heritage or lime mortar restoration. Always follow the specification in your Building Control documentation.
Q: How long before I can plaster or render over blockwork? A: Wait at least 2–3 weeks for the mortar to fully cure, longer in cold or damp conditions. Applying finish too early risks cracks and poor adhesion.
Q: Should I hire a one-person operator or a small team? A: Teams finish faster (better for your timeline), but single operators often charge less daily and suit smaller projects. For walls over 4 metres high, a team with proper scaffolding management is safer and more efficient.
