Local insights
What Affects Builder Costs in Exeter?
The South West has a mix of housing styles, from Victorian and Edwardian semis to 1930s suburban developments and modern estates. In and around Exeter, many properties in areas near Surrey and Kent vary in age and condition. Older properties with original features typically cost more for builder work due to additional preparation and access challenges.
The South West sits above the national average for trade costs, influenced by proximity to London and the generally higher cost of living. Labour rates in Exeter are typically 12% below the UK average. Despite this, there's a strong supply of qualified builder professionals across the region. Prices can vary 30-50% between different tradespeople for the same job, so getting multiple quotes is essential.
What you pay for builder work in Exeter depends on the complexity of the job, the materials used, and the condition of your property. Older detached and semi-detached homes often present more challenges that add to the cost. For larger jobs, expect to pay £43,950 to £123,060 for double storey extension in Exeter. Coastal properties in the South West may face additional considerations that affect pricing.
When getting quotes in Exeter, aim for at least three from different qualified professionals. Ask each one to visit and assess the work rather than quoting over the phone. A good builder will check the existing setup, identify complications, and provide a detailed cost breakdown. Be wary of quotes that seem significantly cheaper — they may be cutting corners on materials or quality. Always check qualifications, insurance and recent reviews.
