Six active developers, one of the fastest-growing towns in Essex - our inspectors cover every CM6 new build scheme








Great Dunmow currently has six active developers operating simultaneously: David Wilson Homes and Bellway at Great Dunmow Grange, Dandara launching St Mary's Park in Spring 2026, Taylor Wimpey at Maynard Park, Wickford Development at Woodlands Meadow, and Bloor Homes on Stortford Road. Uttlesford district grew by 14.9% between 2011 and 2021 - more than double the England average - and Great Dunmow is absorbing much of that growth.
High build volume creates snagging risk. When multiple large sites run simultaneously, subcontractors move between developments, completion pressure builds, and quality control is stretched across sites. Our inspectors cover all active CM6 schemes and consistently find 50 to 200 defects per property - even from NHBC Pride in the Job award-winning site managers like those at Great Dunmow Grange.
CM6 also sits on Anglian glacial boulder clay, the dominant geohazard across north-west Essex. Our inspections include specific checks for drainage management and ground movement indicators particular to clay-heavy sites.

Great Dunmow Grange is the most established new build cluster in CM6. David Wilson Homes is selling final homes from £482,500, with savings advertised of over £80,000 on selected plots. Bellway's Sapphire Fields section offers 2, 3 and 4-bed homes from £464,995 to £674,995. Both sites have NHBC Pride in the Job award-winning site managers - DWH's Connor Bellyou and Bellway's Adam Hawkes both received recognition in 2025.
Award recognition does not mean defect-free properties. Our inspectors attend award-winning sites regularly and find issues at similar rates to other developments. Common findings on large mixed-tenure Essex estates include: incomplete fire stopping between terraced properties, missing vapour barriers in loft eaves areas, kitchen drawer runners that catch, silicone lines that are unfinished, and drainage channels on driveways that run toward rather than away from the garage threshold.

Anglian glacial till (boulder clay) blankets CM6 to considerable depth. The British Geological Survey describes this area as a broad plateau largely composed of boulder clay - a clay-rich substrate with high plasticity and strong shrink-swell behaviour. It expands when wet and contracts in dry summers, causing seasonal ground movement that affects shallow-founded properties.
This matters for new build buyers in Great Dunmow in two ways. First, clay soils drain poorly. A ground investigation in CM6 confirmed that 'a new soakaway would not be possible due to poor ground conditions', which means surface water management cannot rely on simple soakaways. Current planning policy requires Sustainable Drainage Systems (SuDS) on all new estates, but implementation quality varies. Poorly designed SuDS translate into pooling gardens and waterlogged lawns in the first winter after move-in - items that should be flagged as defects within the NHBC warranty period.
Second, clay shrinkage in dry summers causes differential settlement in early-years properties. Hairline cracking at skirting board junctions and slight binding of internal doors are common early indicators. These are warranty items if reported within the NHBC 2-year defects period - the primary reason to get your snagging report documented before completion, not after.
The Environment Agency designates a formal flood alert area covering the River Chelmer from Great Dunmow through to Chelmsford, and a flood warning area from Churchend through Great Dunmow to Little Waltham. Properties near the River Chelmer corridor within CM6 fall within Flood Zone 3 - the highest risk designation. Most active new build estates are on higher plateau ground, but buyers at riverside or low-lying plot positions should check the EA flood map before exchange. Boulder clay's poor drainage also creates surface water flooding risk across plateau areas during heavy rainfall - a separate risk from the fluvial zone.
Dandara's St Mary's Park on Stortford Road is the largest single scheme launching in CM6 in 2026 - 272 homes in total, with 109 affordable units and a show home now open. All properties use air source heat pumps and are designed to high insulation standards under current Building Regulations. Dandara's nearby Little Dunmow scheme prices homes from £350,000 to £755,000, giving a comparable price range for St Mary's Park.
ASHP systems are standard across CM6 new builds but generate their own snagging checklist. Our inspectors check: refrigerant line lagging and UV protection on external pipe runs, adequate clearance around the external unit, commissioning documentation and thermostat settings, hot water cylinder temperature and pressure relief valve, and whether the underfloor heating or radiator system has been balanced correctly for the lower flow temperatures ASHPs require. Incorrectly balanced heating systems are among the most common ASHP-related defects on new estates.

Let us know which CM6 scheme you are buying on. Our inspectors are familiar with Great Dunmow Grange, Sapphire Fields, St Mary's Park, Maynard Park, Woodlands Meadow, and the Bloor Homes Stortford Road site.
We book the inspection 1-2 weeks ahead of your legal completion date. Great Dunmow Grange is on final homes, so completion dates can move quickly - confirming your slot early gives you a reliable window.
Our inspector works through a methodical checklist covering all rooms, external elevations, roof visible areas, drainage, utilities, ASHP installation, and finish quality. All CM6 inspections include standard checks for boulder clay drainage management.
A written report with photographs of every defect is sent within 24-48 hours. Forward it directly to your developer's customer care team. Under the New Homes Quality Board Code, builders must respond formally to reported defects.
NHBC Buildmark provides a 2-year builder warranty covering all defects reported from legal completion. Keep your snagging report and developer correspondence - if issues are not resolved, you can escalate to the New Homes Ombudsman Service.
Snagging surveys in CM6 are priced from £299 for a smaller property, £399-£439 for a 3-bedroom, £449 for a 4-bedroom, and £559 for a 5-bedroom home. On a David Wilson Homes or Bellway property at £500,000-£675,000, the survey costs less than 0.1% of the purchase price. There is no regional premium for the Uttlesford area - CM6 pricing is in line with national averages.
We cover all active CM6 schemes: Great Dunmow Grange (David Wilson Homes final homes), Sapphire Fields (Bellway), St Mary's Park (Dandara launching 2026), Maynard Park (Taylor Wimpey), Woodlands Meadow (Wickford Development), and the Bloor Homes Stortford Road site. We also cover smaller schemes such as Scholars' Green, Venmore Court, and Easton Park as it comes forward. If you are unsure whether your development is covered, contact us with the address.
A 3-4 bedroom property takes approximately 2.5 to 3.5 hours. A 5-bedroom home with multiple en-suites - like the Warwick or Balmoral house types at Woodlands Meadow - typically takes 3.5 to 4 hours. Our inspectors do not rush through rooms; methodical coverage of every wet room, every external junction, and every utility connection is what makes the service effective.
Yes, in two ways. Anglian boulder clay has poor permeability, meaning surface water cannot drain away naturally - new estates require SuDS drainage systems, but implementation quality varies. Poorly graded gardens and blocked drainage channels are among the most common issues on Essex clay-site new builds. Clay also shrinks in dry summers, causing differential settlement in the first few years of a new home. The 2022 heatwave drove a spike in Essex subsidence insurance claims. Our CM6 inspections check drainage gradients and look for early clay movement indicators as standard.
Most are, yes. Dandara explicitly states ASHPs for St Mary's Park, DWH and Bellway use them at Great Dunmow Grange, and Taylor Wimpey installs them as standard across their current national programme. ASHPs create a specific set of snagging items our inspectors check: commissioning documentation, refrigerant line UV protection, ASHP-compatible heating system balance, and hot water cylinder pressure relief valve installation. Incorrectly balanced heating systems - particularly with underfloor heating at low flow temperatures - are among the most reported ASHP-related defects on current new build sites.
Significantly so. Uttlesford district grew by 14.9% between 2011 and 2021, versus 6.6% for England as a whole - more than double the national rate. Great Dunmow has absorbed much of this growth, with six active developers currently building simultaneously. The pipeline includes a 1,200-home government-approved scheme at Easton Park (Landsec) and further strategic allocations that could bring thousands more homes to the area over the next decade. High growth rates mean sustained snagging demand in CM6 for years to come.
The best window is 1-2 weeks before legal completion. At this point your property is in its finished state, your developer still has the strongest obligation to address defects before you take ownership, and your solicitor can confirm the exact completion date. For Great Dunmow Grange where final homes are selling, completion dates can be confirmed quickly once a plot is released. Under the New Homes Quality Board Code of Practice, your developer must allow a Pre Completion Inspection - a professional snagging survey satisfies this requirement.
The Dunmow Flitch Trials is one of the oldest living traditions in England - couples who can convince a jury of six bachelors and six maidens they have not wished themselves unmarried for a year and a day win a flitch of bacon. The custom dates to around 1120, was mentioned in Chaucer's Canterbury Tales, and is still held every four years in Great Dunmow. It does not directly affect property values, but it is a marker of the town's strong local identity and heritage - which, combined with 167+ listed buildings in the conservation area and proximity to Stansted Airport, makes CM6 one of the more distinctive and stable property markets in Essex.
