Independent new build inspections across Stratford, West Ham and the Olympic Park area








Stratford is one of the most active new build markets in London. The Olympic Park legacy programme, now joined by TwelveTrees Park, Legacy Wharf, Sugar House Island, Pudding Mill Lane, and the Carpenters Estate regeneration, is delivering over 8,000 new homes across E15 between 2024 and 2033. With new build flats averaging £393,626 and houses £635,313, the financial stakes for buyers are high.
Our inspectors cover every new build and recently converted property in E15. We know the specific conditions here: former industrial land that required over two million tonnes of remediation before the Olympics, River Lea flood risk, and the hard-learned lessons from East London's largest building safety failures. An independent snagging survey before you complete costs a fraction of your purchase price and identifies every defect while your developer is still obligated to fix them.

E15 currently has more active new build development than almost any other postcode in England. The schemes currently on the market and building include:
On developments of this scale - built by multiple contractors across multiple phases - snagging defects are routine, not exceptional. The HBF National New Homes Survey (2025) found that 93.7% of new build buyers across England reported problems to their builder after moving in, with over 25% reporting more than 15 defects.

The East Village - 66 residential blocks built as the 2012 Olympics Athletes' Village and converted to residential use - is currently facing a £432.7 million fire safety remediation bill. Defects identified include ACM cladding, combustible insulation, missing cavity barriers, and combustible timber on external balconies. The first-ever Remediation Contribution Order under the Building Safety Act 2022 was issued against the developer in January 2024, ordering payment of £18 million. Around 200 shared-ownership leaseholders have been unable to sell since 2020. This scheme was built on one of the most scrutinised development sites in UK history. It is evidence that developer scale and prestige do not guarantee defect-free builds. For all E15 new build buyers - on any scheme, with any developer - independent inspection before completion is not optional. It is the only way to establish a documented record of defects while the developer is still obligated to fix them.

The Lower Lea Valley - where E15's largest developments now stand - was described by the Environment Agency as among the most contaminated land in Britain before the Olympic remediation programme. Former uses included chemical manufacturing, gas works, fertiliser plants, rendering works, engineering depots and metal processing. The pre-2012 remediation treated over two million tonnes of soil using bioremediation, soil washing, and thermal desorption, removing ammonia, arsenic, heavy metals, hydrocarbons, and asbestos. A 450mm cover layer of clean material was placed across the Park site.
The Stratford Gasworks site - adjacent to the Olympic Park - remains a development allocation with contamination considerations. New builds on any former industrial land in E15 should be built with specifically engineered foundations and drainage. Our inspectors check for drainage performance failures, cracking patterns suggesting differential settlement, and any signs of ground movement that might indicate sub-base preparation issues on your specific plot.
E15 also sits within the River Lea and Thames floodplain. Parts of the West Ham area (E15 4) are in Flood Zone 2 or 3. The area is protected by the Thames Barrier and secondary flood defences, but developers building in flood risk zones must incorporate specific mitigation measures. Our inspectors verify that these are correctly installed on new builds in the affected flood zone areas.
Snagging survey pricing for E15 includes London surcharge (standard for providers). Based on HomeSnag London pricing (homesnag.co.uk). A snagging survey costing 0.08-0.11% of purchase price can identify defects worth thousands in remediation.
With 76% of E15 housing stock being flats, the great majority of snagging work in Stratford covers apartment buildings rather than houses. The defect patterns in high-density urban flatted development are different from those in a detached house. Our inspectors pay particular attention to:

Enter your Stratford address and flat or house type online. You get a fixed price immediately. London pricing for E15 starts from £400 for a 1-3 bedroom apartment and is confirmed within minutes.
Snagging surveys must be completed before you exchange or complete. Our inspectors cover the full E15 postcode including Stratford, West Ham, Maryland, and all developments along the Olympic Park fringe. Appointments within 5-7 working days.
Our inspector spends 2-4 hours on your property. For a new build apartment, that includes every room, balcony or terrace surfaces, all services including MVHR and heat pump connections, fire door checks, and a communal areas review relating to your unit's access and egress.
Your detailed snagging report is delivered within 48 hours. Every defect is photographed and precisely located. Present it to your developer before completion - under NHBC Buildmark or LABC warranty they must address all defects. After completion, that leverage significantly weakens.
Snagging surveys in E15 start from £400 for a 1-3 bedroom apartment, reflecting the London surcharge applied by most providers. A 3-bedroom flat or small house typically costs £450-£500, and larger properties £550-£650. The national average is £377 (Compare My Move, 2024), so London pricing runs approximately £25-£75 higher. At TwelveTrees Park, where 1-bed flats start from £495,000, the survey cost is under 0.1% of purchase price. On Legacy Wharf riverside apartments from £375,000, it is 0.11%. The return on that investment is the documented defect list you hold before completion.
The fire safety remediation programme for East Village is underway. If you are buying a resale East Village flat rather than a new build in another E15 development, the relevant survey is a RICS Level 2 or Level 3 survey, not a snagging survey - snagging applies to brand-new or near-new properties under 10 years old. For new developments in E15 being built now - TwelveTrees Park, Legacy Wharf, Pudding Mill Lane, etc. - a snagging survey before completion is the appropriate and recommended inspection. The East Village situation demonstrates why waiting until after completion to investigate quality is a costly mistake.
A 2-bedroom apartment in Stratford E15 takes approximately 2-3 hours to inspect properly. A 3-bedroom flat takes 2.5-3.5 hours. For a new build house, allow 3-4 hours. Our inspectors do not work to a time limit and complete the full checklist regardless. The written report, with photographs, precise defect locations, and recommended actions for each item, is delivered within 48 hours. For large apartment blocks where multiple units need inspecting, we can coordinate group bookings with other buyers in the same development.
On E15's high-density flatted developments, our inspectors most frequently find: inadequate acoustic separation between floors and party walls (the most common complaint post-completion, and very difficult to remediate after handover); fire stopping details that are incomplete or incorrectly installed; MVHR ventilation systems not commissioned to design specification; balcony waterproofing penetrations at fixings and balustrade posts; wet room waterproofing continuity gaps behind fitted units; and external cladding penetrations that are not fully sealed. On ground-level and basement units, drainage fall gradient errors and sump pump commissioning omissions are also common.
The Lower Lea Valley - where the Olympic Park and most of E15's major developments now sit - was among the most contaminated land in Britain before the 2007-2012 Olympic remediation programme. Over two million tonnes of soil were treated to remove heavy metals, hydrocarbons, asbestos, and other contaminants. A 450mm cover layer of clean material was placed across the Park site. Residual contamination is managed rather than fully absent on former industrial plots in E15. For new build buyers, the relevant check is that your developer has obtained appropriate environmental certifications for the site and that drainage and foundations meet the specifications required for that ground. Our inspectors note any signs of differential settlement or drainage performance issues that may indicate sub-base problems.
Most build-to-rent schemes in E15 (like Stratford Mill by Greystar) sell individual units via shared ownership or to investors, as well as letting directly. If you are buying a unit - whether as an investor or shared ownership purchaser - a snagging survey is as valuable as for any other new build. The defects that build-to-rent operators may accept as within-tolerance are not necessarily within your tolerance as an owner. The report documents the condition at handover, which matters for warranty claims during the 2-year developer period and beyond.
Our inspectors cover the full E15 postcode district: Stratford town centre, West Ham, Maryland, Temple Mills, Hackney Wick border, and all sites within or adjacent to the Queen Elizabeth Olympic Park.
