Getting on site with your self build or renovation is often the most exciting phase of a project, as plans start to become reality – but it’s also when your build is most exposed to risk. Ground is broken, trades arrive and materials deliveries start, all before the structure is weathertight or permanent security is in place. Understanding the common risks at this stage and arranging the right protection from the outset can prevent costly delays and financial strain.
At the start of a build, sites are open, partially developed and busy. Materials need to be delivered before installation and structural elements may be temporarily unsupported while alterations take place. Multiple trades working in close succession increases the chance of accidental damage. Renovation and conversion projects carry added uncertainty. Once walls or roofs are opened up, hidden defects such as damp, poor workmanship or structural weakness can emerge. These issues often appear before the project is fully stabilised, increasing cost and complexity.
Structural alterations are a common source of early claims. Works such as removing load-bearing walls, inserting steel beams or altering roof structures all introduce risk. If something goes wrong, repair costs can be significant.
On renovation projects, damage can also affect parts of the existing building that were not due to be altered. Site insurance can include cover for accidental damage to both the new works and the existing structure during the build period.
Construction sites are attractive targets, particularly before security is fully established. High-value items such as tools, copper, heating systems and kitchen units are often stored on site ahead of installation. Theft can cause immediate financial loss and delays, especially if replacement items have long lead times. A suitable site insurance policy can cover stolen materials and, in some cases, plant and equipment – helping to reduce disruption.
Early works are especially vulnerable to the elements. Excavations can flood, high winds can damage partially completed structures, and heavy rain can affect stored materials before the building is sealed. Specialist site insurance can provide cover for storm and flood damage during construction, offering protection when the project is most exposed.
As the homeowner or developer, you are responsible for what happens on your site. Open trenches, uneven ground and temporary access increase the risk of injury. If a contractor, visitor or member of the public is injured, you could face a claim. Site insurance typically includes public liability cover, which protects against injury or property damage arising during the works.
Many homeowners assume their existing buildings policy will be able to accommodate a renovation project. In reality, most standard home insurance excludes or restricts cover once major structural work begins. Claims for theft, storm damage or liability may be declined, leaving homeowners exposed at the point when risk is highest. Arranging specialist site insurance before work starts helps ensure there are no gaps in protection.
Risk is an inevitable part of home construction, particularly in the early stages. Recognising this and putting the right insurance in place from day one protects your investment, your programme and your peace of mind. Specialist site insurance is designed for projects under construction, giving you the confidence to move forward as your build takes shape.
