Home surveys explained: 5 common buyer questions answered

Although property professionals are not expected to provide technical surveying advice, understanding the purpose of a survey can help them clear up common misconceptions and direct buyers towards appropriate professional guidance.

Here are five of the most common questions buyers ask about home surveys.

1. “Do I really need a home survey?”

In England and Wales, buyers are not legally required to arrange a home survey. However, purchasing without one means proceeding with limited independent information about the property’s condition.

A viewing can help someone decide whether they like a property, but it is not a detailed inspection. Issues such as damp, roof defects, timber deterioration or structural movement may not be obvious during a short viewing.

A suitable RICS home survey can provide a clearer understanding of the property’s condition, identify areas requiring further investigation and highlight potential maintenance or repair requirements before the purchase is completed.

Property professionals do not need to recommend a particular survey themselves. Where a buyer is uncertain, they can be encouraged to speak to a qualified surveyor about the property and their circumstances.

2. “Isn’t the lender’s mortgage valuation enough?”

A mortgage valuation is commissioned primarily to help the lender determine whether the property provides suitable security for the proposed loan. It is not the same as a detailed home survey undertaken for the buyer.

The valuation may be completed through a physical inspection, desktop assessment or another method selected by the lender. Its scope is generally much more limited than a Level 2 or Level 3 Survey, and the buyer may not receive a detailed report about the property’s condition.

Making this distinction clear at an early stage can prevent buyers from assuming that the lender’s valuation has assessed every aspect of their prospective home. Buyers who want an independent assessment of the property’s condition should consider arranging a separate home survey.

3. “Which level of home survey should I choose?”

The appropriate survey depends on the property’s age, construction, condition and complexity, as well as the buyer’s plans for it.

A RICS Level 2 Survey is generally suited to conventional houses, flats and bungalows built using common construction methods and appearing to be in reasonable condition. It provides a clear overview of the property and highlights visible defects, their urgency and relevant maintenance requirements.

A RICS Level 3 Survey provides a more comprehensive assessment. It may be appropriate for older, altered, unusual or visibly deteriorated properties, as well as homes requiring extensive renovation. It offers greater detail about identified defects, their possible causes and recommended remedial work.

These are general guidelines rather than a definitive recommendation. A qualified surveyor can advise which level is most appropriate after considering the specific property and the buyer’s requirements.

4. “Will the survey tell me how much repairs will cost?”

A home survey can identify visible defects, explain their significance and advise whether repairs or further investigation may be required. However, buyers should not automatically expect it to provide exact quotations for remedial work.

The cost of a repair can depend on its full extent, the chosen solution, access to the property, materials and local contractor rates. In some circumstances, the surveyor may recommend obtaining specialist advice or contractor quotations before exchanging contracts.

A Level 3 Survey provides more extensive information about repair and maintenance options than a Level 2 Survey, but buyers should check the agreed scope of the service if detailed cost advice is particularly important to them.

The report can help a buyer understand which issues require attention, but further quotations or investigations may still be needed to establish the likely cost of the work.

5. “What happens if the survey uncovers a serious issue?”

A serious finding does not necessarily mean the transaction will fall through.

The first step is for the buyer to understand what has been identified and whether further investigation is recommended. Depending on the issue, they may need to speak to the surveyor, obtain specialist advice, request quotations or raise relevant matters with their solicitor.

Once the buyer has more information, they can decide whether to proceed as planned, budget for future work, discuss the findings with the seller or reconsider the purchase.

Estate agents and mortgage brokers can support this process by helping communication continue between the relevant parties. However, questions about the nature or severity of a defect should always be directed to the surveyor.
