RICS Level 2 Survey in BB11

Burnley expanded rapidly during the nineteenth century as the cotton weaving industry drove demand for workers' housing. The result is a town where Victorian and Edwardian terraced rows account for the overwhelming majority of the housing stock. Many of these properties were built speculatively in back-to-back and through-terrace arrangements using local brick and, in some streets, millstone grit stone. Construction quality varied enormously between developers and decades - some terraces were solidly built and have lasted well with basic maintenance, while others were put up quickly and cheaply and have accumulated significant defects over 130 years.

Our surveyors carry out regular inspections across BB11 and consistently find these issues in Burnley terraces:

• Damp penetration through solid brick or stone walls on exposed north and west elevations, accelerated by Burnley's high annual rainfall
• Chimney stack deterioration - Victorian terraces with multiple original stacks often have deteriorating flashings, cracked pots, and loose or missing pointing
• Roof covering condition - Welsh slate, concrete tile, and clay plain tile on older terraces frequently reaches end of serviceable life without visible signs from street level
• Timber decay in floor joists and roof structures where sub-floor and loft ventilation have been reduced or blocked
• Rising damp at ground floor level in properties where the original slate damp proof course has failed or been bypassed by raised external ground levels
• Settlement cracking consistent with ground movement above historical mine workings in east Lancashire coalfield areas
• Outdated electrical installations with round-pin sockets, rubber-insulated wiring, or consumer units without residual current device protection

The interwar period added a substantial wave of semi-detached housing to the outer parts of BB11, with brick construction becoming standard and cavity walls appearing progressively through the 1930s. These properties carry their own set of potential issues, including failed cavity wall insulation introduced during the 1980s and 1990s, corroded lintels over door and window openings, and cracking associated with shallow foundation depths in clay-bearing ground.

Post-war council housing from the 1950s and 1960s, including non-traditional construction types, is also present in parts of BB11. These properties may contain asbestos-containing materials in textured coatings, floor tiles, and pipe insulation. If you are purchasing a property from this era, an asbestos survey alongside the Level 2 is advisable.

Burnley sits in the Calder Valley in east Lancashire, an area with a complex industrial history and a physical geography that creates real risks for property buyers. Understanding these risks before exchange is exactly what our Level 2 Survey is designed to do.

Coal mining was a major industry across east Lancashire for over two centuries, and BB11 falls within the historical coalfield. Bank Hall Colliery, located within Burnley town itself, operated from 1854 to 1971. Historical drift mines, shallow workings, and bell pits underlie parts of the town, and ground movement above these old extraction zones remains a genuine risk after wet winters. Our surveyors identify cracking patterns consistent with mine-related differential settlement and recommend a Mining Remediation Authority search where there is any doubt. Your conveyancer should include coal mining as a standard search for any BB11 property purchase.

Flood risk is a significant issue in parts of BB11. The River Brun runs through central Burnley and has a history of flooding low-lying streets following periods of heavy Pennine rainfall. The River Calder, which joins the Brun at Burnley, brings additional catchment volume from the upland areas to the east. The Environment Agency maintains two active flood warning areas covering central Burnley: 012FWFL30A (River Calder at Burnley Town Centre, around Cow Lane and St James's Street) and 012FWFL30B (River Calder between Centenary Way and Holme Road). Streets at risk include Parker Lane, Hammerton Street, St James's Street, and Calder Vale Road. Our surveyors check visible evidence of historical flooding during every inspection - tide marks on internal walls, replaced floor coverings, and plaster damage at skirting level. We strongly advise buyers to check the Environment Agency flood map for the specific property address and to confirm flood insurance availability and cost before exchange. Two active Environment Agency flood warning areas cover central BB11: reference 012FWFL30A (River Calder at Burnley Town Centre, around Cow Lane and St James Street) and 012FWFL30B (River Calder at Burnley Town Centre, Centenary Way to Holme Road). Buyers can check flood zone status for any specific property at check-for-flooding.service.gov.uk before proceeding.

Indicative repair costs our surveyors regularly cite for BB11 properties:

• Chimney stack rebuild or major repoint: £1,200 to £3,500 depending on height and access requirements
• Full roof re-cover on a standard terrace with Welsh slate: £4,500 to £10,000
• Penetrating damp treatment and internal replastering: £1,500 to £7,000 depending on affected area
• Rising damp DPC injection with associated plaster hack-off and re-render: £1,500 to £4,000
• Full rewire of a two-up two-down Victorian terrace: £3,500 to £7,000
• Partial floor joist replacement and timber treatment: £2,500 to £8,000

Burnley Borough has ten designated conservation areas, several of which fall within or adjacent to BB11: Burnley Town Centre, Burnley Wood, Canalside (Weavers Triangle), Top O' T' Town, Palatine, Harle Syke, Jib Hill, Hurstwood, Worsthorne, and Padiham. The Canalside and Weavers Triangle area is currently on the Historic England Heritage at Risk Register (reference 4426) - a nationally significant industrial heritage site covering 34 listed buildings along the Leeds and Liverpool Canal corridor. The borough also contains 191 listed buildings, including the Grade I listed St Peter's Church and Grade I Towneley Hall (14th century). Properties within these areas are subject to additional planning restrictions on alterations, and any works carried out without listed building consent or planning permission create a legal liability that passes with the property. Our surveyor notes visible evidence of unauthorised alterations and flags them for your solicitor to investigate.
