Buying older homes can come with plenty of character, history and charm. It can also come with a rather alarming-looking survey.
The survey arrives as a PDF, usually late in the afternoon, and it is longer and more worrying than anybody expected.
Somewhere in it, there is a good chance you will find a recommendation to have the electrical installation inspected and tested by a qualified electrician, and the gas installation and boiler checked by a registered engineer. Sometimes both will be highlighted as requiring further investigation.
It is easy to read that and assume the worst. But in many cases, it does not mean what buyers initially think it means.
Which property survey are you actually getting?
There are three levels of RICS Home Survey, and understanding which one you have commissioned explains a great deal about what you are reading.
Level 1 is the most basic. It provides a visual overview of the property and is generally suited to conventional properties in good condition.
Level 2 is the option many buyers choose. It provides a more detailed inspection, including condition ratings for different elements of the property and advice on repairs and ongoing maintenance.
Level 3 is the most comprehensive. It is particularly suitable for older, larger, altered or unusual properties, or homes where significant work may be required.
If you are buying a Victorian property, a home that has been substantially extended or anything that raised questions during the viewing, a Level 3 survey may be worth considering. For older homes, choosing a surveyor with relevant experience can be just as important as choosing the right survey level.
Why does the survey flag gas and electrics?
Because your surveyor has limitations on what they can inspect and test.
RICS explains that services are often hidden within the construction of a property, meaning a surveyor can generally inspect only visible elements. A standard survey does not include specialist testing of electrical, gas or other energy systems, nor does it establish whether installations comply with current regulations.
Read that again without the panic.
The surveyor is not necessarily saying your wiring is dangerous. They may simply be telling you that they have not tested it and that a specialist should assess it.
A qualified electrician tests electrics. A registered gas engineer checks gas appliances and installations. A surveyor assesses the building.
A recommendation for further investigation can therefore be the surveyor doing their job properly, rather than sounding an alarm.
How do you tell a real problem from a standard caveat?
Look carefully at how the issue is worded and rated.
RICS Home Surveys use condition ratings to help buyers understand the significance of what has been found. Broadly, Condition Rating 1 means no repairs are currently needed, Rating 2 identifies defects that require repairing or replacing but are not considered serious or urgent, and Rating 3 identifies defects that are serious or require urgent attention.
You may also see NI where something has not been inspected.
The important distinction is between a general limitation and a specific observation.
“Services were not tested and we recommend inspection by a qualified person” is very different from the surveyor identifying visible evidence of a potential electrical problem.
If you are unsure which you are looking at, speak to the surveyor. They can explain what they observed, what is a standard limitation and which findings deserve further investigation.
What can you do without immediately spending more money?
Start with the paperwork.
Ask the seller whether they have relevant documentation, such as a recent boiler service history, electrical reports or certificates relating to previous work.
Find out when the consumer unit and boiler were last replaced and whether certification is available.
You can also ask for building regulations documentation relating to relevant alterations or installations where applicable.
If suitable documentation is unavailable and the survey recommends further investigation, you can then consider arranging the appropriate specialist inspection.
What can a survey flag in older homes that may simply reflect their age?
Quite a lot. This is where buyers of period properties can understandably become nervous.
Older buildings were constructed differently from modern homes and need to be understood in that context.
Solid walls, traditional lime mortar, historic timber movement and uneven floors can all be features of an older property. Moisture readings also need to be interpreted appropriately for the age and construction of the building rather than automatically judged against the expectations of a modern home.
That does not mean every issue should be ignored. It means context matters.
A surveyor experienced with older homes should be able to distinguish between characteristics associated with the property’s age and defects that warrant further investigation or repair.
It is another reason to consider a Level 3 survey for a period property and to ask whether your chosen surveyor regularly works with buildings of a similar age and construction.
Should you use the survey to renegotiate?
Sometimes.
If the survey uncovers a significant issue that you could not reasonably have known about when making your offer, it may be appropriate to discuss it with the seller.
However, a survey can be more useful as a practical to-do list than as a negotiation tool.
Returning to the seller with a long list of standard caveats and maintenance recommendations is unlikely to be as productive as highlighting a small number of significant, unexpected issues supported by specialist advice or quotations.
“The report mentions the roof” starts a conversation.
“Here is a written quotation for the work identified” gives both sides something concrete to discuss.
Buying an older property locally?
If you are considering a property with a little age and character and would like some guidance on what you might expect from older homes in the local area, speak to us.
We see plenty of survey reports and understand that a long list of observations does not necessarily mean you have chosen the wrong property. We would rather help you understand what you are buying so you can make your decision with your eyes open.
Frequently asked questions
Why does a survey recommend checking the gas and electrics?
A standard RICS Home Survey does not include specialist testing of electrical and gas installations. A recommendation for further inspection may therefore reflect the limitations of the survey rather than evidence that something is necessarily wrong.
What do the condition ratings in a survey mean?
Condition Rating 1 indicates that no repair is currently needed. Rating 2 identifies defects that require repair or replacement but are not considered serious or urgent. Rating 3 identifies serious defects or issues requiring urgent attention. NI means an element was not inspected.
Which survey should I get for an older house?
A Level 3 Home Survey is designed for properties where a more detailed assessment is appropriate, including older, larger, unusual or significantly altered homes. The right survey will ultimately depend on the individual property, so it is worth discussing your choice with a RICS surveyor.
What should I ask the seller after a survey?
Ask what documentation is available for relevant installations and previous work. This could include boiler servicing records, electrical reports and certificates, and building regulations documentation for relevant alterations.
Can I reduce my offer because of the survey?
You can renegotiate following a survey, although the seller is not obliged to accept a revised offer. A discussion is likely to be more constructive when it focuses on significant, previously unknown issues supported by specialist advice or written quotations.
