What Determines Renovation Costs Per Square Metre?
Several factors influence the final price per square metre. Being aware of these helps you understand why quotes differ and where your money goes.
- Scope of work: A simple redecoration is far cheaper than moving walls, rewiring, or replacing structural elements.
- Property type and age: Victorian terraces often hide damp, outdated wiring, or asbestos, adding to the base cost. Newer builds may require less preparation.
- Quality of materials: Laminate flooring costs under £20/m², while solid hardwood can exceed £80/m². Similar ranges apply to kitchens, bathrooms, and finishes.
- Labour rates: Tradespeople in London and the South East typically charge 30–50% more than those in northern England or Wales.
- Access and location: Difficult access (e.g., upper‑floor flats without a lift) or congestion‑charge zones can increase labour time and disposal costs.
- Planning and regulations: Listed buildings or conservation areas may require specialist materials and extra permissions, pushing up costs.
Average Building Renovation Costs Per m²
The table below gives typical price ranges for different renovation levels. These are estimated market averages and include labour and materials (excluding VAT).
| Renovation Level | Typical Cost per m² | What’s Included |

Note: Prices are indicative and can vary significantly with project complexity and location. Always obtain multiple detailed quotes.
Renovation Cost by Room Type
Different rooms demand different levels of expenditure due to plumbing, electrics, and specialised fittings.
| Room | Typical Cost per m² (mid‑range) | Key cost drivers |
|---|---|---|
| Kitchen | £1,500 – £2,500 | Units, worktops, appliances, plumbing & gas works |
| Bathroom | £1,200 – £2,200 | Sanitaryware, tiling, waterproofing, plumbing |

Regional Price Variations Across the UK
Labour rates and material logistics cause notable differences across the country. Below are estimated average per‑square‑metre costs for a mid‑range renovation.
| Region | Average Cost per m² (mid‑range) |
|---|---|
| London | £1,800 – £2,500 |
| South East | £1,600 – £2,200 |
| Midlands | £1,300 – £1,800 |
| North England | £1,100 – £1,600 |
| Scotland | £1,000 – £1,500 |
| Wales | £1,000 – £1,500 |
| Northern Ireland | £950 – £1,450 |
Costs in rural areas can be higher due to travel surcharges. Always confirm whether quotes include VAT.
Labour vs Material Cost Breakdown
For a typical mid‑range renovation, the split between labour and materials is roughly 60% labour / 40% materials. This varies by trade – tiling and plastering are labour‑intensive, while kitchen units are more material‑heavy.
| Cost Component | Percentage of Total |
|---|---|
| Labour | 55 – 65% |
| Materials & Finishes | 30 – 40% |
| Waste removal & contingency | 5 – 10% |
Additional Costs to Consider
- VAT: Most renovation work is subject to 20% VAT unless it qualifies for reduced rates (e.g., certain conversions or work on empty properties). Always ask whether the quote is VAT‑inclusive.
- Skip hire / waste disposal: Budget £200–£500 depending on skip size and location.
- Building regulations fees: For structural work, expect to pay £200–£800 for inspections.
- Architect / structural engineer: If you change layouts, fees can be £500–£2,000+.
- Temporary accommodation: If the property is uninhabitable during work, factor in rental costs.
How We Estimated These Prices
The figures in this guide are compiled from a combination of UK contractor quotations, supplier catalogues, industry market research, and regional labour rate surveys. They represent estimated market averages and not official government statistics. Prices are reviewed periodically and reflect realistic contractor pricing rather than theoretical minimums.
We considered factors such as average day rates for electricians (£200–£250), plumbers (£180–£230), plasterers (£150–£200), and general builders (£180–£250), alongside material costs from major UK retailers.
Common Mistakes That Increase Project Costs
- Choosing unsuitable materials: For example, using non‑breathable paint on old solid walls can lead to damp problems, requiring expensive repairs later.
- Ignoring preparation work: Skipping proper plaster preparation or damp proofing can ruin a renovation.
- Hiring only on price: The cheapest quote may cut corners or exclude essential tasks.
- Forgetting VAT and hidden charges: Always clarify what is included in the quoted figure.
- Ordering insufficient materials: Last‑minute purchases often cost more and cause delays.
- Not getting written contracts: Verbal agreements can lead to disputes over scope and price.
How to Save Money on Your Renovation
- Get at least three itemised quotes and compare like for like.
- Do some preparation work yourself, such as stripping wallpaper or clearing the site, if safe.
- Source materials during sales or from trade suppliers – but ensure quality isn’t compromised.
- Consider a phased renovation if the budget is tight; prioritise structural and essential works first.
- Hire a reputable main contractor who can coordinate multiple trades, often saving time and money.
Hiring Checklist
- ✓ Get at least three written quotations.
- ✓ Check previous work and ask for references.
- ✓ Confirm insurance (public liability).

- ✓ Ask what is and isn’t covered (waste removal, materials, etc.).

Frequently Asked Questions
The average cost for a mid‑range renovation is £1,200–£1,800 per square metre, including labour and materials. Basic cosmetic work starts around £800/m², while high‑end structural renovations can exceed £2,500/m².
Not always. Many contractors quote ex‑VAT, so always check. Most renovation work attracts 20% VAT unless it qualifies for a reduced rate (e.g., converting a property from commercial to residential).
A full structural renovation typically costs £1,800–£2,500+ per square metre. This includes new plumbing, electrics, plastering, kitchen, and bathroom. For a 100 m² property, the total would range from £180,000 to £250,000+.
Higher labour rates, congestion charges, parking restrictions, and higher disposal fees push London prices up. Labour alone can be 30–50% more than in the North.
Get multiple quotes, do some preparation work yourself, buy materials in sales, and prioritise structural works over cosmetic finishes. A phased renovation can also spread the cost.
Renovation is usually cheaper than a new build if the existing structure is sound. However, extensive structural issues can make a full rebuild more cost‑effective in the long run.
