Figures are typical UK averages including labour, materials, and VAT at 20% for standard-rated work.

Typical UK Cost Ranges for Cost per m²

All prices are approximate UK averages including labour, materials, and VAT at 20% (2026). Some qualifying renovations for empty homes may use the reduced 5% VAT rate.

Real UK Cost Examples

• Budget scenario (70m² 2-bed flat, North East): Cosmetic update with decorating, flooring and limited service upgrades. Effective range: about £700 to £1,000 per m² (around £49,000 to £70,000 total).
• Mid-range scenario (95m² 3-bed semi, West Midlands): Balanced renovation including kitchen, bathroom, flooring and partial service updates. Effective range: about £1,100 to £1,600 per m² (around £105,000 to £152,000 total).
• High-end scenario (140m² period detached, South East): Structural changes, premium materials and whole-home service upgrade. Effective range: about £1,800 to £2,600 per m² (around £252,000 to £364,000 total).

What You Can Get For Your Budget

• Around £800 per m²: mainly cosmetic work plus selective compliance upgrades.
• Around £1,300 per m²: balanced renovation with meaningful specification improvements and some service work.
• £2,000+ per m²: complex or premium renovation where structural and service scope is significant.

Hidden Costs to Watch For

• Per-m² shortcuts often miss fixed costs such as scaffolding, design fees and preliminaries.
• Small floor areas can look expensive per m² because setup costs are spread over fewer metres.
• Access constraints and programme delays distort headline m² assumptions quickly.
• Regional labour variance can override generic national m² benchmarks.

Should You Use a per m² Model?

• Worth using at planning stage to compare options quickly and set guardrails.
• Not enough on its own for final commitment; detailed scope-based quotes are still essential.
• Per-m² planning improves decision quality, but return depends on specification discipline and local value ceilings.

Common Cost Mistakes

• Treating per-m² numbers as fixed prices rather than range indicators.
• Ignoring fixed-cost items that do not scale with floor area.
• Comparing quotes with different scope and calling one “cheaper per m²”.
• Skipping a contingency because the m² figure appears precise.

Key Cost Factors

• Scope of work — cosmetic updates cost far less per m² than structural changes.
• Finish level — budget, mid-range, or premium materials and fixtures.
• Property type — flats are typically cheaper per m² than houses due to fewer external elements.
• Age and condition — older properties with damp, asbestos, or outdated wiring cost more.
• Room type — kitchens and bathrooms are the most expensive rooms per m².
• Location — London and the South East add 15–40% to per-m² costs.

Why Cost per m² Often Misleads Homeowners

• Per-m² figures are useful for feasibility, but they hide fixed costs such as preliminaries, skips, scaffolding and design fees.
• Two homes with the same floor area can have radically different totals if one needs rewiring, damp treatment or major layout change.
• Room mix matters: kitchens, bathrooms and structural alterations cost far more per m² than bedrooms and simple decorative areas.

Ways to Reduce Costs

• Focus on high-impact rooms (kitchen, bathroom) and keep other areas cosmetic.
• Use the cost-per-m² figures to set a realistic budget before getting quotes.
• Compare quotes on a per-m² basis to identify good value.
• Reduce per-m² costs by doing painting and flooring yourself.
• Plan all work together to avoid tradespeople revisiting.
