CB24 is home to two of England's most ambitious new towns. Independent snagging inspection protects your investment in Northstowe and Waterbeach.








The CB24 postcode district, stretching north from Cambridge through Histon, Cottenham, Longstanton, and Waterbeach, contains two of the most significant new settlement projects in England. Northstowe - planned to reach 10,000 homes and become Cambridgeshire's largest town - is already occupied by 1,750 households. Waterbeach New Town has outline planning consent for 11,000 homes across two phases, with CALA Homes delivering the first 111 properties and a new railway station scheduled for 2027.
We have been inspecting new builds at Northstowe since the earliest phase completions. Both settlements were planned to be exemplars of sustainable placemaking. Both have experienced the gap between ambition and delivery. Northstowe residents waited years for a single shop, cafe, or GP surgery. Bovis Homes - one of the major builders at Northstowe - paid \u00a37 million in compensation to new build customers in 2017 following national complaints about build quality and customer service. At these prices and at this scale, an independent snagging survey is not optional - it is the only way to ensure your home has been built to the standard you paid for.
Our inspectors cover all developments across CB24, from the established villages of Histon and Cottenham to the active phases at Northstowe and Waterbeach. We check 150+ items per property, use thermal imaging cameras, and deliver your report within three working days.

Bovis Homes - one of the principal housebuilders at Northstowe in CB24 - agreed to pay £7 million in compensation to new build customers in 2017 following widespread complaints about build quality, incomplete snagging rectification, and poor customer service. The company was forced to take back properties, offer refunds, and provide additional payments to hundreds of affected buyers. While Bovis has since undergone changes as part of the Vistry Group, the case remains the most significant builder accountability episode in modern UK housebuilding. HomeViews residents at Northstowe continue to note variability in build quality and customer service between individual developments. An independent snagging survey, carried out before or immediately after your completion, is the most effective tool available to document defects while the NHBC warranty obligation remains fully enforceable.
CB24 contains two strategic development sites that between them will eventually deliver 21,000 new homes - the largest concentration of new build construction in the Cambridge sub-region:
In the established villages of Histon, Impington, Cottenham, and Bar Hill, the picture is different: fewer volume housebuilder sites and more individual plots or small private developments. Buyers in these villages may be purchasing properties from a wider age range of stock, where a Level 2 or Level 3 survey may be more appropriate than a snagging inspection.
The CB24 postcode district spans the edge of the Cambridgeshire Fens - one of the most geologically complex areas for construction in England. The Fen lowlands are characterised by peat, silt, and alluvial clay: soft, compressible soils that can cause differential settlement over time. At Northstowe and Waterbeach, developments are sited on the slightly higher Fen edge, but the boundaries between competent ground and soft Fen deposits are not always obvious and require careful geotechnical investigation.
Surface water drainage is a critical concern on Fen edge sites. Unlike chalk or gravel areas, water does not drain quickly through the subsoil. Inadequate surface water management around new properties can result in standing water, damp DPC conditions, and blocked gullies within the first year of occupation. Our inspectors check the falls of hard landscaping, the height of damp-proof courses above finished ground level, and the outlet points of all surface water drainage routes.

A snagging survey costs less than 0.1% of the purchase price on every CB24 new build. Defects resolved under NHBC warranty at zero cost to the buyer - avoiding post-warranty repair bills that can exceed £10,000.
In our inspections across new build sites in the Cambridge sub-region, the most common defects we find on CB24 properties fall into predictable categories. Across high-volume sites like Northstowe, where multiple non-qualified tradespeople work alongside qualified site managers, workmanship consistency varies between plots.
The Keepmoat Stirling Fields development uses closed-panel timber frame construction - a modern method that, when installed correctly, delivers excellent airtightness and energy performance. However, site-installed components such as service penetrations, socket back-boxes, and partition walls require careful sealing to maintain the thermal envelope. Our inspectors are experienced with timber frame properties and know where to look.

Snagging surveys in CB24 start from £295 for a one-bedroom flat and range to around £445 or more for a four-bedroom house. At Northstowe, where Bovis Homes properties are priced from £450,000-£542,000, the survey cost is less than 0.1% of the purchase price. This makes it one of the most cost-effective forms of due diligence available to a new build buyer. Defects identified and submitted to the developer under the NHBC warranty are resolved at no cost to you - often far exceeding the survey fee in value.
Yes - and the case is particularly strong at Northstowe given the history of build quality concerns at the development. Bovis Homes paid £7 million in compensation to customers in 2017 following national reports of substandard build quality, and HomeViews reviewers at Northstowe continue to note variable workmanship and customer service. Even where individual build standards have improved, the scale and pace of construction at a 10,000-home new town increases the statistical likelihood of individual defects. An independent inspection gives you a documented record to enforce your NHBC warranty rights.
Most snagging surveys on CB24 new builds take 3 to 5 hours on site depending on property size. A two-bedroom flat at Keepmoat Stirling Fields may be completed in 2.5 to 3 hours. A four-bedroom detached house at Bovis Homes Northstowe will typically take 4 to 5 hours, including a full roof space inspection, exterior elevation check, and garage if included. Your written report is delivered within three working days of the inspection.
Yes - pre-completion inspections (PCIs) are available and strongly recommended at both Northstowe and Waterbeach. Under the New Homes Quality Board (NHQB) code, buyers have a legal right to request a pre-completion inspection with two weeks' notice to the developer. This gives you maximum leverage: any defects identified before legal completion can be formally listed as conditions of exchange, preventing your developer from dismissing them as 'move-in damage' later. Both Northstowe and Waterbeach are live construction sites with regular completions, and we typically have good availability within 5 to 7 days of your preferred date.
Based on snagging surveys across Cambridge sub-region new builds, the most common defects at large-scale developments like Northstowe include: missing or displaced loft insulation (visible on thermal camera), inadequate mastic sealing around windows and doors, surface drainage gradients too shallow causing water accumulation near the property, plasterboard fixed to timber studs at insufficient intervals causing hollow sections, and cosmetic finishing issues including poorly applied emulsion and misaligned skirting boards. At Keepmoat's Stirling Fields development, which uses timber frame construction, air leakage around electrical back-boxes and service entries is a particular area to check.
The Waterbeach New Town site sits largely within Flood Zone 1 (lowest risk), but the adjacent Fen landscape means the site edges are managed as transition zones with specific drainage requirements. At Northstowe, the site is on slightly elevated ground above the Fen, but surface water drainage is still a design challenge given the low permeability of the Fen-edge soils. Our snagging inspections check damp-proof course height relative to external ground levels and hard landscaping falls, which are the primary indicators of whether drainage has been properly designed for the specific plot.
Yes - all new homes built by Bovis Homes, CALA Homes, Keepmoat, and other active housebuilders at Northstowe and Waterbeach come with a 10-year NHBC Buildmark warranty. The first 2 years cover all defects reported to the developer, with the developer obliged to repair at no cost to you. Years 3-10 cover major structural defects directly through NHBC. A snagging report creates a formal, dated record of defects that you submit as a written defect notice to your developer - which is far more effective than an informal complaint and gives you a clear paper trail for escalation to NHBC if needed.
Yes - we cover all areas within the CB24 postcode district including the established villages of Histon, Impington, Cottenham, Longstanton, Willingham, Over, Milton, and Bar Hill. In these villages, most properties are not new builds, and a RICS Level 2 or Level 3 survey may be more appropriate than a snagging inspection.
