How to Plan a Home Extension in the UK
Where to start, planning permission, and a realistic timeline.
Read the guide →FAQ
How much does a home extension cost in the UK?+
£1,500–£3,500/m²
Typically £1,500 to £3,500 per square metre depending on the type and spec. A standard single-storey rear extension of around 20m² usually costs £40,000 to £56,000 before VAT and professional fees. See our full extension cost guide for a spec-by-spec breakdown.
How do I calculate a home extension cost?+
Area × Rate
Multiply your extension's floor area in square metres by the per-m² rate for your extension type and spec level, then add 20% VAT, professional fees of roughly £3,000 to £10,000, and a 10–15% contingency on top.
Is a double-storey extension cheaper per square metre than a single-storey one?+
Yes
A double-storey extension typically costs £1,500 to £2,400 per square metre, compared with £1,800 to £3,000 for a single-storey extension, because the foundations and roof are shared across two floors.
Do I need planning permission for a home extension?+
Often Not
Many single-storey rear extensions fall under Permitted Development and don't need planning permission, but there are size and boundary limits. Larger extensions, side returns near a boundary, and most two-storey extensions usually do need planning permission.
What's included in the per-square-metre extension price?+
Labour & Materials Only
The per-m² build rate covers labour and materials only. VAT, architect and structural engineer fees, Building Regulations fees, and any planning application fee are usually on top, not included in the headline £/m² figure.
How much do professional fees add to an extension cost?+
£3,000–£10,000
Budget roughly £3,000 to £10,000 for architect drawings, a structural engineer, and Building Regulations approval, depending on the complexity of the extension.
