Why is Building Work So Expensive in the UK?

If your recent building quote left you shocked, you’re not alone. Whether you’re a homeowner, developer, or contractor in the UK, many are asking the same question: why are construction costs so high? The answers are complex—but this guide breaks them down clearly.

As RICS-chartered quantity surveyors, we see firsthand how rising costs affect projects across residential, commercial, and public sectors.

Let’s dive into the main reasons driving up prices—and how to manage them.

The Real Reasons Behind the Rising Costs

From global material shortages to compliance rules and labour shortages, many factors are pushing UK construction prices up. Here’s what’s driving the increases—and how they affect your project:

1. Material Price Inflation

Costs for basics like timber, bricks, steel, insulation, and concrete have surged—some by 20% to 80%—due to ongoing global instability, supply chain issues, and post-Brexit/pandemic effects. Overall, material prices rose over 40% from 2020 to 2023.

2. Skilled Labour Shortages

With fewer skilled tradespeople (bricklayers, electricians, carpenters), wages are rising—sometimes by 10% to 25%—because demand exceeds supply. Brexit and an aging workforce have worsened this shortage.

3. Regulatory and Compliance Costs

Modern building regulations around fire safety, energy performance (Part L), ventilation (Part F), and more all increase costs. CDM and environmental compliance add further layers of expense.

4. Professional Fees and Statutory Costs

Projects now often require input from many professionals—architects, engineers, energy assessors, quantity surveyors—and include fees like planning, building control, CIL, and Party Wall Awards. These can quickly reach five figures before any foundation is laid.

5. Finance and Risk Premiums

Uncertainty in material supply and inflation causes contractors to build higher risk allowances into their bids. This means higher upfront quotes or costly change orders later on.

6. Poor Planning and Scope Creep

Without clear early definitions and strong management, little changes or vague briefs can escalate costs. That’s why professional cost planning is so valuable.

Real-World Cost Impact

As an example, a modest rear extension that cost around £1,500/m² in 2019 may now be priced at £2,000–2,500/m². Medium housing projects that were £1,400/m² are now approaching £1,700–1,800/m², especially when high-tech or energy specs are involv

How You Can Control Costs
You can’t control global trends—but you can plan smartly:

• Engage a Quantity Surveyor Early to help set realistic budgets, value-engineer designs, and manage competitive tendering.

• Finalise your Design Early to avoid costly late changes.

• Use Competitive Tendering with multiple qualified bids overseen by a QS.

• Avoid Unqualified Contractors—cheap quotes often lead to delays and extra expense.

• Plan in Phases if budgeting is tight—this spreads costs and risk..
