On-Site Survey · London
On-site reinstatement cost assessment in London.
The most accurate rebuild cost available — a full physical survey by a RICS-regulated surveyor. Essential for London’s listed, period, complex and high-value buildings, delivered with full site evidence.
What it is
A surveyor on site, measuring every detail.
An on-site reinstatement cost assessment is the gold standard. A RICS-regulated surveyor attends your London property in person, measures every element, and assesses the specification and construction first-hand. Nothing is estimated from records alone.
This level of detail matters most where a building is out of the ordinary — a listed townhouse, a period conversion, a mixed-use block, or an industrial unit with significant plant. The result is a comprehensive, evidenced rebuild figure that stands up to insurer and legal scrutiny.

Who needs it
Built for London’s harder buildings.
Listed & period buildings
Heritage detailing and traditional materials that generic indices cannot value accurately.
Non-standard construction
Timber frame, steel frame, concrete and other builds that need expert on-site judgement.
Complex commercial & industrial
Large floor plates, plant rooms, M&E installations and mixed-use premises across London.
High-value assets
Prime central London property where an accurate, evidenced figure protects a significant sum.
Why it matters
Detail is where the value hides.
London holds some of the most complex building stock in the country — Georgian and Victorian terraces, mansion blocks, converted warehouses and prime commercial premises. On these buildings, generic calculators and desktop indices routinely miss six-figure sums in specialist materials, heritage detailing and services.
Underinsurance on a high-value asset is a serious exposure. Under a policy’s condition of average, a shortfall reduces every claim proportionally. An on-site survey removes the guesswork and gives owners, freeholders and managing agents a figure they can defend with total confidence.

Frequently Asked Questions.
Common questions about on-site reinstatement cost assessments for London property.
What is an on-site reinstatement cost assessment?
An on-site reinstatement cost assessment is a full physical survey carried out by a RICS-regulated surveyor who attends your property, measures every element in person, and assesses specification and construction. It is the most accurate way to establish a rebuild cost, and is essential for listed, complex or high-value buildings.
When do I need an on-site survey rather than a desktop assessment?
An on-site survey is recommended for listed buildings, non-standard or period construction, complex commercial and industrial premises, and high-value assets where a desktop assessment cannot capture the full detail. If your London property has specialist materials, curtilage structures, M&E installations or a large floor plate, an on-site survey is the right choice.
How long does an on-site assessment take in London?
The inspection itself typically takes a few hours depending on the size and complexity of the building. The full written report, including site notes and photographic evidence, is usually delivered shortly after the visit. We arrange appointments across London to suit access and management schedules.
Will the report stand up to insurer or legal scrutiny?
Yes. An on-site RICS assessment provides a comprehensive, evidenced rebuild figure with full site notes and photographs. It is BCIS-indexed, broker-ready, and prepared to withstand insurer challenge or legal scrutiny.
Do you survey listed and period buildings in London?
Yes. Our surveyors are experienced in listed building requirements, specialist materials, period detailing, curtilage structures and complex M&E, which are common across central and inner London.
