How much does a home extension cost in Bath?

Homeowners in Bath usually spend in the region of £20,000–£70,000 on a home extension. South West costs are broadly around the national average — Somerset labour and materials are a real factor. Expect single vs double storey and floor area and planning, glazing and finish quality to move the price most, along with foundations and structural work. Getting two or three quotes is the best way to see a fair local price, which is exactly what our free matching service arranges.

Figures are a 2025 guide only — your matched installer will give you an accurate, no-obligation quote.

How long does it take?

In Bath, expect a typical home extension to take about 3–6 months once work begins.

  • Hire a structural engineer. Essential where load-bearing walls are removed, for safety and compliance.
  • Match your materials. Choose brick and finishes that harmonise with your existing home.
  • Plan for the long term. Design for how you’ll use the space in five and ten years, not just now.

Home Extensions in Bath: the 2025 guide

Why a home extension makes sense in Bath

For many Bath homeowners, a home extension is the practical alternative to moving. A well-built extension typically adds both significant living space and long-term property value.

Planning your home extension in Bath

Good preparation pays off: nail down your must-haves, keep a contingency in reserve, and choose a Bath installer on reputation and paperwork rather than the lowest number.

Local know-how for Bath

Property in Bath tends to reflect Somerset: Bath-stone and rendered cottages, Levels farmhouses and Georgian terraces. Getting a home extension right in Bath means working with that character — the somerset levels’ flood risk and mendip aonb are worth checking early. A local specialist who knows Bath will factor all of this into your quote and design.

Choosing the right Bath professional

Choosing the right person is the hardest part. Rather than sifting through directories and reviews, Renomate does the legwork — we match you with a vetted Bath specialist for your home extension, check their credentials, and introduce you personally.
