Safety Testing & Certification for Property Developers in Portsmouth

Start with the planning and demolition paperwork. Some planning permissions and local authority demolition responses ask for pest control before a building comes down, and the Building Act 1984 gives the authority powers over demolition that include requiring drains to be disconnected and sealed. Under the Prevention of Damage by Pests Act 1949, the authority can also require the owner or occupier of land to deal with rats or mice. Share any conditions and correspondence with bidders so each proposal responds to what has actually been required.

A pre-start survey should record signs of activity, likely harbourage, the condition of drains and manholes, neighbouring uses that could be affected, and any evidence of birds or bats. Ecology is a separate discipline. The Wildlife and Countryside Act 1981 protects nesting birds and the Conservation of Habitats and Species Regulations 2017 protect bat roosts, so if the survey finds signs of either, the developer's ecologist needs to advise before work proceeds. Pest control cannot be used as a way around those protections.

Treatment before demolition usually runs for a set period of baiting and trapping, followed by checks that activity has fallen before the structure is disturbed. The rodenticide stewardship code expects bait to be used for a defined purpose and period and then removed, with any bodies found collected and disposed of. The technician should also look at redundant drains, because rats commonly live in and travel through them, and a disconnected drain that is not properly sealed gives them a route into the site and beyond.

During construction, monitoring points around welfare cabins, skips and site boundaries show whether activity is returning. The principal contractor controls site access and induction under the Construction (Design and Management) Regulations 2015, so the pest control firm's visits, risk assessments and method statements need to fit those arrangements. Food waste from welfare areas is one of the most common attractants and is controlled by site housekeeping rather than by pest control; covered skips and daily clearance make monitoring results easier to read.

Before handover, attention moves to the finished building. New drainage, cable ducts, service entries and gaps around pipework can all let rodents into completed homes or units. Approved Document H includes guidance on rodent control in drainage, and a final inspection can check that redundant connections are sealed, access covers are secure and service penetrations have been closed. The result is a dated record of what was inspected and found, not a certificate that the building will stay free of pests.

Proposals worth comparing set out the survey scope, how long pre-demolition treatment is planned to run and what would extend it, the frequency of construction-phase visits, how records will be provided for planning or local authority purposes, and what is excluded, such as bird proofing at height or drain repairs.
