Hundreds of new build homes are coming to BA4 - make sure yours is defect-free before you move in








With up to 620 new homes planned at Cannards Grave Road alone - plus active developments at Thorne Lane and Somer Meadows nearby - Shepton Mallet is one of Somerset's fastest-growing new build markets. Our inspectors have caught everything from poorly sealed limestone pointing on barn conversions to drainage failures on brand-new estates backing onto the River Sheppey floodplain.
A snagging survey gives you a documented list of defects your developer must fix before completion - or hand over to rectify under the 2-year builder warranty. Our BA4-based inspectors know the specific issues affecting new builds on Mendip ground, including drainage requirements tied to Somerset's phosphate rules and the ground conditions around the area's historic quarrying sites.
Average house prices in BA4 have reached around £330,000, making this one of the most significant purchases most buyers will ever make. A snagging survey costing from £295 is one of the most cost-effective protections available.

The River Sheppey runs through Shepton Mallet town centre, and several streets carry active Environment Agency flood warnings - including Garston Street, Leg Square, Lower Lane, Longbridge, and Draycott Road. Storm Henk in January 2024 affected over 50 properties across Shepton Mallet, Bruton, Croscombe, Knole, and Nunney. Any new build plot in BA4 should be checked against the EA flood map before exchange. Our inspectors flag drainage design issues - particularly surface water and groundwater management - on new build sites in flood-risk zones.
New build developments on the edge of Shepton Mallet sit on Jurassic limestone - the same Doulting Stone and Downside Stone that has been quarried here since Roman times and used to build Wells Cathedral. This geology has implications for new build sites: drainage engineering must account for limestone permeability, and groundwater conditions vary across plots on the same development. Our inspectors check drainage gradients, soakaway design, and surface water run-off management as standard on every BA4 inspection.
BA4's newer developments - including Thorne Lane and schemes around Cannards Grave Road - use standard brick-and-block construction, which means our inspectors focus on mortar joint quality, cavity insulation continuity, lintel bedding over openings, and window and door frame sealing. We also verify that radon-resistant membranes have been correctly installed: the Mendip Hills area carries moderate-to-elevated radon potential due to the underlying Jurassic limestone, and Building Regulations require protective measures in affected postcodes within BA4.
Internal snagging covers every room systematically: plasterwork finish and paint coverage, tiling alignment and grouting in kitchens and bathrooms, floor levelness, door and window operation, stair balustrade fixings, and all fitted appliances. Our inspectors photograph every defect and organise findings by room so you can present the report to your developer's customer care team in a format they cannot dispute or dismiss.

Somerset's phosphate neutrality rules - which paused thousands of new build approvals across the county - have shaped how the 620-home Cannards Grave Road development in Shepton Mallet has been designed. Developers in this area must demonstrate that new properties will not increase phosphate loading in the Somerset Levels waterways. In practice, this means specific drainage and landscaping arrangements are built into new schemes.
Our inspectors check that drainage infrastructure matches approved plans and that no shortcuts have been taken on surface water management - particularly critical on sites backing onto the River Sheppey catchment. Phosphate mitigation measures are a relatively new requirement, so build quality on these points benefits from independent verification before you complete.
Alongside phosphate compliance, we check standard snagging items: plasterwork finish, paintwork coverage, tiling alignment, door and window operation, floor levelness, and utility connections. On average, our inspectors find between 100 and 400 individual defects on a new build - all documented in your written report.

Select a date that works around your developer's schedule. Our inspectors cover Shepton Mallet, Evercreech, Castle Cary, Pilton and all BA4 postcodes with flexible appointment times including weekdays and Saturdays.
Our inspector arrives at the agreed time and carries out a detailed inspection of all accessible areas - inside and out. The inspection typically takes 2-4 hours depending on property size. The developer or sales agent can be present if you prefer.
Your full snagging report arrives within 24-48 hours. It lists every defect with photographs and descriptions, organised by room and area. You use this report to formally request repairs from your developer.
Present the report to your developer before completion - they are legally obligated to address genuine defects. If completing before fixes are done, your report supports warranty claims during the 2-year developer liability period.
Snagging surveys in BA4 and the wider Shepton Mallet area start from £295 for smaller properties and range up to around £500 for a 5-bedroom house. The national average is £377 (Compare My Move, 2025). Prices depend on property size and complexity - a flat in a Shepton Mallet town-centre conversion typically costs less to survey than a 4-bed detached on one of the larger new build estates. Our quotes are fixed price with no extras.
New build properties in BA4 are not automatically inspected to the standard that an independent snagging surveyor provides. Developers run their own quality checks, but these are conducted by people employed by the developer. Our inspectors consistently find 100-400 defects on new build properties - defects that are the developer's responsibility to fix. Given the scale of new build activity planned around Shepton Mallet, including the 620-home Cannards Grave Road development, having an independent inspection before completion is strongly recommended.
A standard snagging inspection on a 3-bedroom new build in BA4 takes approximately 2-3 hours on site. Larger 4 or 5-bedroom properties typically take 3-4 hours. Your written report follows within 24-48 hours. The inspection covers all accessible rooms, the loft, the external envelope including brickwork, roof, windows and drainage, and all fitted items including kitchen, bathroom, and utility room.
Yes - and this is generally the best time to have it done. Most developers will allow access for an independent snagging inspection in the two weeks before your legal completion date. Having the report before completion gives you the strongest negotiating position: you can formally request repairs before you hand over your money. If the developer refuses access before completion, you can still use the snagging report to make warranty claims during the 2-year liability period.
Our inspectors pay particular attention to drainage design and surface water management on BA4 sites, given the River Sheppey flood history and the limestone geology that affects water movement through the ground. Radon-resistant membrane installation is another BA4-specific check: the Mendip Hills area has moderate-to-elevated radon potential, and Building Regulations require protective measures in affected postcodes. Standard checks also cover cavity insulation continuity, mortar joint quality, roof tile and ridge finish, and all internal fit-out items.
Snagging surveys are designed for new build homes, not traditional conversions or older properties. If you are buying a converted barn or farm building in one of the BA4 villages - Batcombe, Ditcheat, Pilton, Evercreech or surrounding areas - you would typically need a RICS Level 3 Building Survey rather than a snagging inspection. A Level 3 survey is designed for older properties, non-standard construction, and significantly altered buildings. We can provide quotes for both survey types.
Your snagging report is a formal document you own, not something the developer has any control over. You can submit it directly to your developer's customer care team and request a written response to each individual item. If the developer disputes defects or fails to act, you can escalate to the New Homes Ombudsman Service (NHOS), which all registered developers are required to participate in under the New Homes Quality Code. Your solicitor can also use the report if legal action becomes necessary. Developers generally respond to clearly documented reports because ignoring them creates legal exposure and reputational damage on local Facebook groups and community forums.
On properties where the purchase price runs to several hundred thousand pounds, a snagging survey costing from £295 represents a small fraction of the transaction value. Our inspectors typically identify defects that cost developers significantly more to fix than the survey fee - which is why the financial case is strong regardless of property size. For smaller homes in Shepton Mallet town centre or the more affordable parts of BA4, the survey still pays for itself if even a handful of defects are identified and properly rectified before you complete.
