Our Approach

An ethical approach to every undertaking

Surveyor on site representing professional ethics and standards.
01

Ethics

We are regulated by the Royal Institution of Chartered Surveyors and professional ethics are central to our ethos.

Surveying and inspection work that reflects efficient professional practice.
02

Efficiency

As an RICS Tech Partner we build surveying software, including in-house tools that shorten the gap between site inspection and issued report.

Detailed building inspection image representing transparency and integrity.
03

Integrity

Advice is given against the lease and the evidence on site, not against the outcome a client prefers. Where a defect is overstated or outside tenant liability, we say so in writing.

Property survey image used to represent sustainability and responsible project delivery.
04

Sustainability

Inspection routes are planned to limit site visits. Reports are delivered digitally and reuse photographs and CAD data already gathered for the survey.

Where Roof Design Meets Condensation Risk

Two timber-framed roof lanterns formed part of a recent external inspection we undertook on a mansard roof in West London. Both featured single glazed elements, limited overhangs, and decorative paint finishes in poor condition.

The presence of condensation to internal glazing, along with signs of historical repair and timber exposure, highlights a common set of issues—particularly in traditional or poorly detailed roof structures.

Where single glazed rooflights are retained in occupied spaces, internal dampness is frequently the result of thermal bridging or trapped moisture, rather than rainwater penetration alone.

In such cases, replacement offers the opportunity to introduce modern, thermally efficient materials and more robust junction detailing—reducing risk and improving long-term performance.

About Heathrow

Heathrow Industrial Units

Heathrow Airport and its surrounding industrial perimeter sit at the western edge of Greater London, across the London Boroughs of Hillingdon and Hounslow and extending into Slough in Berkshire, with major clusters at Hatton Cross, Bath Road, Colnbrook, Stanwell, and the cargo area at the southern perimeter. The Heathrow industrial belt accommodates thousands of units across air cargo and freight forwarding warehouses, in-flight catering production, ground services, vehicle and plant servicing, hotels, and substantial car parking, with proximity to the airport generating the highest concentration of logistics and distribution floorspace in west London. The stock spans general industrial (B2) production buildings, storage and distribution (B8) high-bay air cargo warehouses, light industrial workshops, specialist in-flight catering premises, mid-century freight sheds with asbestos-cement sheeting, and recent composite-panel high-bay warehouses with dock-leveller loading and integrated customs and security installations. Surveying instructions commonly include terminal dilapidations on industrial leases, schedules of condition at lease commencement, reinstatement cost assessments on large-span buildings, party wall awards arising from neighbouring intensification, and asbestos surveys on mid-century premises.

Air Cargo and Logistics Stock

The cargo and logistics buildings around Heathrow span several generations of construction. Mid-century freight sheds are typically steel portal frames with profiled metal or asbestos-cement sheeting, limited insulation, and single glazing. Recent stock comprises composite-panel high-bay warehouses with insulated standing-seam roofs, dock-leveller loading, secure airside access, and specialist customs and security installations. Common defects include asbestos-cement sheeting on the older premises, corroded steelwork at gutter and eaves, failed rooflights, water ingress at roof junctions, racking and fork-lift impact to perimeter walls and steel columns, cracked or displaced concrete floor slabs from heavy air-cargo handling, worn dock-leveller installations, and end-of-life electrical and sprinkler systems. Dilapidations exposure in the air cargo belt is frequently driven by roof and cladding condition, floor slab repair, yard surfaces, and asbestos management obligations. Reinstatement cost assessments need to reflect the replacement cost of large-span buildings together with specialist customs, security, and air-cargo handling installations.

Dilapidations and Schedules of Condition

Tenants around Heathrow face material dilapidations exposure on industrial leases because of the age of much of the building stock and the heavy use that floor slabs, yards, and dock-levellers experience. A schedule of condition recorded at lease commencement is intended to limit terminal dilapidations liability and is routinely instructed for new leases. Terminal schedules require assessment of repair, reinstatement, and statutory obligations, including asbestos management, fire compartmentation between adjoining units, and Minimum Energy Efficiency Standards on the building.

Hotel Stock, Planning Constraints, and Party Wall Work

Alongside the industrial market, the hotel cluster along Bath Road and around Hatton Cross generates external wall system assessments (EWS1) and Building Safety Act compliance work on higher-rise stock. The Heathrow perimeter is subject to planning constraints including aircraft noise contours, public safety zones, and height restrictions, which affect redevelopment options and the cost of statutory compliance. Party wall awards and schedules of condition on adjoining buildings are routine where the airport operator, neighbouring landowners, or large logistics developers undertake construction adjoining established occupiers.
