Managing Contractors - A guide for Residential Property Owners [Hardfacts]


Failing to ensure that contractors work safely can and does lead to many accidents and injuries to the contractor's employees, tenants, their visitors and people living nearby. This has resulted in civil claims for compensation and criminal prosecution against landlords. It is important to understand what the law requires of landlords and how to put this into practice to avoid such incidents.

Legal Duties

The legal situation is spelt out in the Health and Safety at Work etc Act 1974:

Section 3 requires employers, and the self employed to ensure that the way they conduct their undertaking does not endanger persons not in their employ.

Using a contractor is one way in which a landlord "conducts" his or her "undertaking". You can therefore be criminally liable should the contractor cause injury for example, to a tenant.

It is important to show that you have done what is reasonably practicable to reduce any such risk.

In its widest sense, the term "Contractor" does not merely refer to building contractors.
It includes any individual or company who comes onto your property to fulfil a contractual obligation between the landlord and a third party company.

"Contractors" could include:

  • Telephone engineers
  •  Window cleaners
  •  Contract cleaners
  •  Plumbers
  • Electrical/mechanical maintenance engineers
  •  Grounds Maintenance/Gardeners.

There are other more detailed legal requirements for construction work. If you are engaging contractors to undertake construction or demolition work (as defined), the Construction (Design and Management) Regulations will apply.

Selection of Contractors

Firstly, it is necessary to clearly identify all aspects of the work the contractor is required to undertake.

When selecting contractors, health and safety aspects must be taken into account as well as the competence of the contractor to complete the work. Landlords or their agents need to satisfy themselves that contractors are competent (i.e. they have sufficient skills and knowledge) to do the job safely and without risks to health and safety.
The landlord questioning a potential contractor should establish:

 What experience they have in the work required.

  • Their health and safety performance (number of accidents, etc)
  • What qualifications and skills they have
  • If they have any independent assessment of their competence
  • If they are a member of a reputable trade or professional body (details of such organisations are given in the Yellow Pages Telephone Directory).

Landlords or their agents are then in a position to decide how much evidence (such as taking up references) they need to take in support of what they have been told by the prospective contractors.

Insurance Checks

As part of the selection procedure landlords should also include a check that the contractor has adequate employers' liability and public liability insurance cover. It is recommended that Public Liability insurance should give at least £5 million cover and ideally should be sufficient to cover the full reinstatement value of the property where the work is being undertaken.

Many accidents involving contractors have happened because of a failure to plan the job properly. i.e. taking account of health and safety aspects which are likely to arise. A risk assessment needs to be made by the contractor and communicated to all involved.
Landlords should make any relevant information they have, available to the contractor.

Tenants need to be consulted on the nature of the work and how it will affect their occupation of the premises. It is helpful to seek their co-operation.

Clear Responsibilities

The work to be done, the areas in which the contractors can operate, together with what can and cannot be done, should be clearly defined.

Monitoring and Contractor Appraisal

The client is responsible for monitoring the health & safety performance of the contractor as work progresses. This could include periodic inspections. If the contractor is undertaking their work in a way that endangers your tenants or the public, it is essential that you draw it to their attention.

When the contractor has finished the work, an important decision has to be taken: In the light of our experience, would we offer the particular contractor the job again?

A simple log should be kept by the landlord or their agent of any incidents or concerns arising during the course of the works, which should be reviewed with the contractor with a view to improving performance.

Key Action Steps

  • Adopt a structured approach to the selection of contractors
  • Check contractors carry adequate Employers and Public Liability Insurance
  • Consult tenants on what work is to be carried out to ensure access etc. and segregation of tenants from the work activities where appropriate
  • Require that contractors adopt formal procedures to ensure that works are carried out with due regard to health & safety
  • Keep a record of incidents occurring during the works and review with the contractor
