List Your Business

Andover's expanding residential landscape — from the Victorian terraces around the town centre to the sprawling post-war estates towards Picket Twenty and beyond — means homeowners increasingly seek space without moving. Whether you're adding a rear extension to a traditional High Street townhouse or converting a loft above a 1970s semi in Cricklade or Shenley Church End, finding a reliable extension builder in Andover matters. The town's strong property market, fuelled by commuters to London and professionals working across the aerospace and engineering hubs in the wider Test Valley region, has created genuine demand for quality home extensions. If you're a self-employed extension builder serving Andover and the surrounding villages — Abbotts Ann, Penton, Weyhill — BizHub365 helps you quote faster, invoice professionally, track materials costs, and manage cash flow so you can focus on building.

Extension Builders Serving Andover and Surrounding Areas

Andover's rapid residential expansion has driven strong demand for extension builders. The town's Victorian and Edwardian properties across the central conservation area and newer estates in the Charlton and Picket twenty neighbourhoods require skilled building work. Extension builders here serve beyond town limits into Hampshire's prosperous commuter belt, Amesbury, and the villages of the test valley, where period properties command premium extension projects.

Frequently Asked Questions

How much does a house extension cost in Andover?
Single-storey extensions typically cost £1,500–£2,500 per square metre in Andover depending on specification, materials, and existing property condition. Two-storey work runs higher. Always ask for itemised quotes breaking materials and labour separately.
What planning permission do I need for an extension in Andover?
Single-storey rear extensions under 3 metres (or 4 metres for corner plots) with a pitched roof may qualify for permitted development. Most other extensions need planning approval from Test Valley Borough Council. Check your property's location before committing.
How long does an extension build take in Andover?
Small single-storey extensions typically take 8–12 weeks from foundation to completion. Larger two-storey builds run 16–24 weeks. Weather, material delays, and inspection timings all affect the schedule. Your builder should confirm dates in writing.
Is my extension builder VAT registered in Andover?
Ask to see their certificate. VAT-registered builders must charge 20% on labour and materials unless building a new dwelling (zero-rated). Sole traders turning over under £85,000 may not be registered—always clarify this upfront.
