Independent new build inspections for buyers at Corelli and across the DT9 postcode in Sherborne, Milborne Port and the surrounding villages








Sherborne is best known for its medieval abbey, independent schools and Georgian stone townhouses - but the DT9 postcode has seen significant new build activity over the past decade, most notably through Persimmon's Corelli development. With over 450 homes built on that estate alone, plus smaller schemes across Milborne Port and the surrounding villages, there is a substantial stock of new build properties in DT9 whose buyers needed a thorough pre-completion inspection.
An independent inspection by a Channel 4 programme found 295 snags in a Persimmon property, with 70% so serious they fell outside building regulations tolerance limits. That figure is an industry benchmark now. Our inspectors use that context when arriving at a Persimmon property - they know what to look for, where builders cut corners, and how to document defects in the format that triggers a repair response.

2021 Census - historic market town with active new build pipeline
Sherborne occupies a distinctive position in the Dorset property market. The town centre is largely built from Ham stone - the warm golden limestone quarried at Ham Hill near Yeovil - giving it a heritage character that contrasts sharply with the brick and render of the new build estates on its fringes. Buyers moving into Corelli or similar schemes are entering a very different type of property to the period townhouses of the town centre, and the defect profile reflects that difference.
New builds in DT9 are predominantly constructed with cavity brick walls, timber roof trusses, and increasingly, heat pump installations replacing gas boilers. Each of these elements has a set of common defect patterns: inadequate cavity insulation, poorly fitted roof bracing, and heat pump systems commissioned without the correct settings. A snagging inspection checks all of these areas systematically.
The Corelli development in Sherborne - Persimmon's 450-home estate - has generated well-documented resident complaints. After close to 10 years on site, residents reported incomplete roads, blocked drains, hazardous pavements, unsafe metal fencing and streetlighting that was never installed. Ward councillors raised concerns with Dorset Council, and a Dorset Live investigation documented soil heaps, piles of building rubble and unfinished communal areas left in place as residents moved in.
The site-level infrastructure issues are one dimension of the problem. Individual property defects are another. A Channel 4 Dispatches investigation found 295 snags in a Persimmon property independently inspected for the programme - 70% of which were serious enough to fall outside building regulations tolerance. Buyers at Corelli who had a professional snagging inspection before or immediately after completion were significantly better placed to use their two-year warranty entitlements than those who waited.

Persimmon's two-year builder warranty covers defects in workmanship and materials for the first two years from legal completion. After that, you are left with the NHBC structural warranty only. If you bought at Corelli and have not yet had a professional snagging inspection, the clock is running. Defects identified and reported to Persimmon within the two-year window must be rectified at their cost. Defects reported after this period become the homeowner's liability. Book an inspection before your warranty expires - do not wait until you notice a problem.
Enter your DT9 property type and address on our quote form. Prices are fixed based on property size - no hidden fees, no additional charges unless you add optional extras like thermal imaging.
We offer inspection slots across the week including weekends. Coverage extends across the full DT9 postcode including Sherborne, Milborne Port, Bishops Caundle, Stalbridge and all surrounding villages.
Armed with moisture meters, socket testers, laser levels and a digital reporting system, our inspector works through 400+ check points covering every accessible part of the property. On a three-bedroom semi this takes around 2.5 hours.
The digital report is structured with photographs, defect severity ratings and precise room-by-room locations. A summary list is formatted for sending directly to your developer's customer care team.
We provide guidance on how to submit your report to Persimmon or any other developer, and what response timelines to expect under the New Homes Quality Code. If your builder fails to respond, escalation routes to the NHBC Resolution service are clearly outlined.
All prices include full written report with photographs, delivered digitally within 24 hours. Thermal imaging add-on available for buyers concerned about insulation quality or MVHR systems.
The inspection covers every room and every accessible external area. At Corelli and similar DT9 new builds, our inspectors pay specific attention to the areas that have generated the most complaints in Persimmon properties nationally - fire stopping in party walls, cavity barrier installation, drainage falls and structural connections at roof level.
After the inspection, our inspector confirms verbally which items they consider most significant before the full written report is delivered. This gives you a head start in deciding which defects to prioritise in discussions with your developer.

Our snagging surveys in DT9 start at £295 for smaller properties including one and two bedroom flats. A typical three or four bedroom semi-detached house at Corelli or similar developments costs from £355. Larger detached properties start from around £420. All prices include a full written report delivered digitally within 24 hours. Thermal imaging is available as an add-on for buyers wanting to check insulation quality, cold bridges or heat pump performance.
Based on the documented record at Corelli and Persimmon developments nationally, yes - and strongly so. A Channel 4 Dispatches investigation found 295 snags in a Persimmon property, 70% of which fell outside building regulations tolerance. The Corelli estate has also generated complaints about drainage, roads and site infrastructure that suggest systemic quality control gaps. Our inspectors find an average of 80-150 individual items in new build properties - at a Persimmon development, the report typically pays for itself several times over in repairs carried out at the developer's expense.
A two or three bedroom semi-detached property at Corelli typically takes around 2.5 to 3 hours. A larger four or five bedroom detached house may take up to 4 hours. Our inspectors do not rush the process - every area on the checklist is completed before the inspection closes. Inspections requiring access to loft spaces, garages and rear gardens take longer than properties without these features, and we factor this into our scheduling.
Yes. While pre-completion inspections are the most effective timing, a snagging survey at any point within the two-year builder warranty period is valuable. If you bought at Corelli or another DT9 development within the last two years, you are still within the window where Persimmon or your developer is obligated to fix defects in workmanship and materials. Our report provides the evidence base you need to formally raise those defects and require a response under the New Homes Quality Code.
Our reports are formatted to meet NHBC standards and the New Homes Quality Board code of conduct, making them directly usable in any formal dispute process. If your builder does not respond within the timeframe required under the code, you can escalate to the New Homes Ombudsman or, for NHBC registered properties, use the NHBC Resolution service. Our team can advise on which escalation route applies to your property and provide supplementary documentation if required.
DT9 is a large postcode district covering Sherborne town, Milborne Port, Bishops Caundle, Stalbridge, Templecombe, Long Burton, Nether Compton, Over Compton and numerous surrounding rural villages. We cover all of these areas without additional travel charges. If your property sits just outside the DT9 boundary - for example in adjacent TA or SP postcodes - contact us with your exact address and we will confirm coverage within the hour.
Our inspection focuses on the individual property and its plot boundary - the building itself, drainage connections to the highway, the private garden and any garage or outbuilding included within the sale. We do not inspect communal infrastructure such as estate roads, shared lighting columns or management company-maintained areas. However, if we identify that a drainage connection between your property and the highway appears incomplete or non-compliant, we note this in the report and recommend you raise it with both your conveyancer and the developer before completion.
Reports are delivered digitally within 24 hours of the inspection completing. Friday inspections receive reports by Monday morning. For buyers approaching a legal completion deadline - when 24 hours is too long - we offer a 4-hour expedited delivery for a small additional charge. Please mention this at the time of booking and we will allocate an inspector and time slot accordingly.
