Vendor liaison checklist

Vendor liaison checklist

This content outlines some tips on liasing with vendors.

This is live content and is supporting information only. It is not intended to be mandatory or prescriptive guidance.

Before the inspection, get as much information from the vendor, occupier or the person in charge of the property as possible. The exact process and timing of this depends on the circumstances, but the more upfront information you obtain, the better informed you will be.

RICS members/ regulated firms can find further supporting information on the Health & Safety and Equipment checklist.

Where relevant and practical, the vendor and/or the owner or their agent should be asked to provide appropriate information as outlined in the RICS Home Survey Standard 1st edition Professional Statement, section 3.2. Where information is offered, the RICS member and/or regulated firm should keep a clear record.

RICS has produced a range of practical guides to enable RICS professionals to work safely and in line with government guidelines through the COVID-19 pandemic.

The RICS COVID-19 guide to surveying services: Physical inspections for the purpose of residential valuations and condition-based surveys includes recommendations for before, during and after a physical inspection.

COVID-19 is having an impact on industry professionals whose work involves direct contact with clients, occupiers, tenants and home movers whether in an office or through visits to a private residential property. This is causing significant uncertainty for many, especially as Government guidance continues to evolve.

The guidance focuses on physical contact points in the home moving process whereby professionals delivering services will need to come into contact with people and/or enter private residential properties. This includes guidance for consumers and recommended questions to ask vendors/occupiers prior to physical inspections. The guidance can be found here COVID-19 guides to surveying service.

In addition, RICS members and / or regulated firms may find the Home Buying and Selling Group industry guidance on COVID-19, which contains useful consumer guidance on safe home moving to ensure clarity, transparency and a smooth process for all parties.

Please note as the situation and guidance in this area is constantly evolving, we intend for this information to be updated regularly.

Many firms will have their own policies on engaging with vendors. Please refer to your company’s policy throughout the delivery of your service.

Using vendor questionnaires

The surveyor will use reasonable endeavours to capture relevant information pre-inspection to support the service. A questionnaire completed by the vendor should be regarded as one of the pre-inspection checks. The process of developing and implementing your own questionnaire largely depends on how you are instructed and the procedures you prefer to follow. Completing the questionnaire in advance of the inspection can save time on the day and it gives the vendor time to locate all the necessary information (guarantees, certificates, etc) at their convenience. However, it is important to remember that the questionnaire has been written and presented in plain, easy to digest language.

If the vendor has completed the questionnaire, you may need to refer to the responses during your time at the property because many of the answers can give an insight into condition and may have to be followed up.

Alternatively, if the questionnaire isn’t completed in advance, it could be completed at the time of inspection:

  • If practical to do so, give the questionnaire to the occupier at the start and ask them to complete it while you inspect the property. This gives them some time to complete the form and find all the necessary information. Read the completed form to make sure you have the necessary information; or
  • If practical, talk to the vendor as soon as you arrive and go through each question verbally. This allows you to explain and discuss the topics in more depth, gives you a good insight into the property, and establishes a positive relationship with the vendor.

Building a relationship with the vendor – on arrival

A positive relationship with the vendor can reveal a lot of useful information about the property. It may be useful to follow a systematic procedure to build a positive relationship and demonstrate responsible, professional behaviours:

  • Arrive on time with proof of your identity.
  • Explain the purpose of the inspection.
  • Outline your approach to the inspection – how long it will take (you should already have confirmed the probable length of your inspection prior to inspection), what rooms and spaces you will need to inspect, etc.
  • Deal with the vendor's questionnaire if appropriate (see above).
  • Ask the vendor to briefly show you around the property. This introduces you to the property, allows you to ask gentle but probing questions, enables you to assess any safety risks, and make arrangements for inspecting occupied areas, for example, bedrooms with sleeping occupants, etc.
  • Ask the vendor to open any hatches and access panels that they would open during the normal use of the property – this will not only save you time, it will help you carry out a more thorough inspection.
  • Ask the vendor to remove any obstructions from hallways, windows if practical etc.
  • Ask the vendor if there are any defective elements that may be damaged if operated or checked, such as windows that do not shut, taps that cannot be operated.
  • If the only person in the property during the inspection is below the age of 18, or is someone who you judge to be vulnerable in some way, you must postpone your inspection until an adult or carer can be present. In this instance, please also refer to your company policy.

Once the initial and brief walkabout is complete, politely inform the vendor you want to carry out the rest of the inspection on your own.

Dealing with vendor enquiries

Whatever the circumstances, many sellers will be very interested in what you thought of their home and what you might include in your report. This can be a difficult discussion because you are there working for the buyer to whom you owe the primary duty.

Avoid being drawn into discussing controversial issues you may have just spotted or commenting on the findings during the inspection. One of the best explanations is to say you cannot come to instant judgments and need to review your notes before you come to any firm conclusions. It will help everyone if you stay as neutral as possible.

Where information is offered by the vendor/occupier, the RICS member should keep a clear record. This must be securely stored and accessible in compliance with current data protection legislation and regulations.

RICS professionals and RICS regulated firms are expected to behave ethically and professionally, while taking adequate steps to consider health and safety at all times for all parties involved.

The information contained here is regularly reviewed to support members in safely delivering the highest level of service.
