New homes above 300 years of coalfield workings need a specialist check - our inspectors cover every NHBC standard








Whitehaven has two active volume new-build developments in 2026: Story Homes' Edgehill Park on Wilson Pit Road (2-5 bedroom homes from £164,950) and Gleeson Homes' Ivy Mills on Main Street (2-4 bedroom homes from £165,995). Both sit on ground with a 300-year coal mining history. The street name Wilson Pit Road is a direct reference to a former colliery - Whitehaven is the historic heart of the Cumberland Coalfield, where over 70 pits were sunk across three centuries.
Our snagging inspectors check every new home against NHBC Buildmark standards before legal completion. On a CA28 site, specific checks include drainage performance on glacial and colliery-disturbed ground, wall crack patterns consistent with differential settlement, correct installation of cavity wall insulation, and thorough commissioning of all mechanical systems. Both Story Homes and Gleeson Homes carry NHBC Buildmark warranty - confirming your snagging items in writing before completion creates a legal record for the full 10-year warranty period.
The average house price in CA28 is £178,542. Story Homes' 4-bed detached plots at Edgehill Park reach £329,950. A snagging survey from £295 is the smallest line item in your moving budget and the one that protects the largest.

Story Homes is running their Edgehill Park development on Wilson Pit Road in Whitehaven. The scheme offers 2, 3, 4 and 5-bedroom detached and semi-detached homes plus townhouses, priced from £164,950 for a 2-bed semi (The Oxley) to £329,950 for a 4-bed detached (The Sanderson). Story Homes' CA28 offering targets a broad range of buyers including first-time buyers through to families upgrading - the site has fell views and is within walking distance of the town centre.
Gleeson Homes' Ivy Mills development at Main Street CA28 covers 2, 3, and 4-bedroom homes priced from £165,995 (The Boston, 2-bed semi) to £297,995 (The Dalkey, 4-bed detached). Gleeson operates a 5% deposit contribution incentive. Both Edgehill Park and Ivy Mills carry NHBC Buildmark 10-year warranty.
Boutique schemes are also active in CA28: Hilltop Heights at Kells offers 3-bed semis at £265,000, while Cantle Grove at Harras Moor has 3-bed bungalows at £459,950 and High Stile Gardens at Hensingham features dormer bungalows at £425,000. On smaller schemes, warranty registration is worth confirming explicitly - Premier Guarantee, LABC Warranty, and Build Zone are alternatives to NHBC used by some local developers.

Whitehaven is the historic heart of the Cumberland Coalfield. Over 70 colliery shafts were sunk in the Whitehaven area across three centuries of coal extraction. Underground workings extend up to 5 miles out under the Irish Sea from both Haig Colliery (closed 1986) and the earlier William Pit. All CA28 property transactions require a Coal Mining Report (the CON29M from the Mining Remediation Authority) as standard - no mortgage lender will proceed without one in this area. The CON29M flags historic underground workings, former shaft locations, and recorded subsidence claims. Wilson Pit Road - the address of Story Homes' Edgehill Park development - references the former colliery infrastructure in that part of the town. Developers building on CA28 land must demonstrate to NHBC that adequate ground investigation has been carried out. NHBC Buildmark warranty includes cover for mining subsidence within the 10-year warranty period, which is one of the most important protections you hold as a new-build buyer in this postcode.

Whitehaven holds a remarkable distinction: it was one of the first post-medieval planned new towns in England, laid out from 1680 by Sir John Lowther on a right-angled grid. The town predates Edinburgh New Town by 80 years and is described by some architectural historians as the most complete example of Georgian planned architecture in Europe. Over 170 listed buildings stand in CA28 - an extraordinary density for a town of 24,000 people.
The Georgian core is built in St Bees sandstone - a red-pink Triassic sandstone quarried 3 miles south at St Bees Head. Lowther's original specifications required houses 'to be of hewn stone' with specific facade dimensions. The conservation area covering the Georgian grid means any works to these properties require Cumberland Council approval. Listed building consent is needed for alterations to the fabric.
This heritage context matters for new-build buyers too. New homes at Edgehill Park and Ivy Mills are built in standard brick - not sandstone - but they sit within or adjacent to a townscape with a very specific character. Planning conditions on these sites may require brick colour matching and external material constraints. A snagging inspection does not review planning compliance, but if your plot is subject to an architectural design code, your solicitor should confirm compliance before completion.

Tell us the development name, plot number, and property type. We confirm price and availability within 2 hours. Whitehaven inspections start from £295 for a 2-bed. We cover the full CA28 district including Hensingham, Kells, Mirehouse, Sandwith, and Harras Moor.
Our inspector contacts Story Homes or Gleeson directly to arrange access before your legal completion date. Developers are required to allow a pre-completion snagging inspection. We handle the scheduling and confirm the date with you in advance.
Our inspector works through every room, all external elevations, the roof and loft (where accessible), drainage connections, and all installed systems. On CA28 sites, we pay particular attention to crack patterns and floor levels as indicators of early differential settlement. A standard 3-bed takes 3-3.5 hours.
A detailed PDF report with photographs and NHBC standard references for every defect. You send this to your developer and solicitor before exchange or completion. Items identified before completion have maximum legal weight.
Your developer's NHBC Buildmark responsibility period runs for 2 years from legal completion for most defects. Our snagging report creates a clear record from day one. If the developer disputes any item, we can provide a supplementary technical note.
Snagging surveys in CA28 start from £295 for a 2-bed property. A 3-bed semi at Gleeson Ivy Mills or Story Homes Edgehill Park is typically £345-£375; a 4-bed detached is £375-£420. We confirm your exact price when you request a quote. On a Story Homes Sanderson (4-bed, £329,950), the snagging fee is less than 0.1% of the purchase price. On a Gleeson Boston (2-bed, £165,995), it is under 0.2%.
They are different products that complement each other. The CON29M (Coal Mining Report) is a legal search commissioned by your solicitor from the Mining Remediation Authority. It confirms whether the property sits on or near recorded underground workings, former shafts, or areas with subsidence claims history. CA28 is firmly in the Cumberland Coalfield and a CON29M is mandatory for any mortgage lender. A snagging survey is a physical inspection of the finished building - it looks at construction quality, workmanship defects, and early signs of any differential movement. The CON29M tells you about the ground history; the snagging survey tells you about the building quality. You need both.
Book as soon as the developer confirms a legal completion date and the property is substantially finished. The ideal timing is 2-4 weeks before the planned completion date. This gives time to receive the report, send it to your developer, allow the developer to respond, and - if any critical items remain - for your solicitor to use the report in completion negotiations. Booking early in the completion window means you are not racing against a countdown. Call us as soon as you have a completion target from Story Homes or Gleeson.
This is a reasonable question for any CA28 buyer. NHBC requires that any new-build developer on land with a mining legacy carries out adequate ground investigation before construction. If the developer used NHBC-approved design and build standards, their foundations will have been designed for the ground conditions identified. The NHBC Buildmark warranty covers mining subsidence for the full 10-year period. Our snagging inspection looks for early signs of differential movement - internal plasterboard cracking at junctions, door and window frames out of square, floor level variation. These can be early indicators on any new build, including sites with no mining history. On CA28 sites, we document the baseline condition carefully so any subsequent movement can be measured against it.
Yes. A snagging survey can be commissioned for any new-build property within NHBC warranty - including harbourside apartment conversions or new-build flats. For harbour-front properties in CA28, we add specific checks for salt-exposure corrosion on external metalwork, balcony drainage, weep vents in masonry, and window seals on sea-facing elevations. Harbourside flats in Whitehaven (such as those on West Strand and Strand Street) also sit in or near Environment Agency Flood Zone 2/3 - flood resilience features such as flood doors or airbrick covers should be installed and operational if specified in the planning consent.
A snagging survey is exclusively for new-build properties, typically within the first 2 years of an NHBC warranty. For a Victorian sandstone terrace in Whitehaven's conservation area, a RICS Level 2 or Level 3 building survey is the right product. A Level 3 is strongly recommended for any pre-1919 property given the construction type (St Bees sandstone with lime mortar, solid floor construction, no cavity walls), the potential for ground movement from underlying coal workings, and the complexity of assessing older building fabric. Whitehaven has around 170 listed buildings - for any listed property, a RICS Level 3 and a separate specialist heritage report may be appropriate.
Both Story Homes and Gleeson operate at volume with standardised house types and construction processes. On Story Homes builds, our inspectors most commonly find finishing-trade inconsistencies - kitchen unit alignment, bathroom tile grouting, and plasterboard finishing around service penetrations. On Gleeson builds (which target the affordable market and build at faster pace), we more frequently find drainage fall issues, cavity insulation gaps detectable by thermal imaging, and ASHP or heating system commissioning that is incomplete at legal handover. Whitehaven's west-coast weather exposure means external sealant quality matters more here than in more sheltered locations.
West Cumbria has elevated radon potential compared to the England average, reflecting the underlying Carboniferous geology. Whitehaven itself is not typically classified as a primary Radon Affected Area requiring mandatory action-level assessment under Building Regulations - that designation applies primarily to granite-underlain areas such as Cornwall, Devon, and parts of Derbyshire. However, the probability is non-zero, and any new build constructed since 2000 in a moderate radon area should have a radon-resistant membrane installed. Our snagging inspection confirms whether radon protection measures have been correctly installed where specified. Post-occupation radon testing (UKHSA-approved detector kits) is a separate step worth taking 6 months after moving in.
