Residential Surveys
Residential Surveys London
A mortgage valuation tells your lender what the property is worth. It tells you almost nothing about its condition. A residential survey from a RICS chartered surveyor is what tells you what you are actually buying.
Somerset & Sinclair offer Level 2 and Level 3 surveys for residential buyers across London and nationwide. If you also need a formal valuation, we can arrange that alongside your survey.
RICS Level 2 Homebuyer Survey
The Smart Check Before You Hand Over Your Deposit
Most London properties look fine on a viewing. That’s the point. A Level 2 Homebuyer Survey gets past the surface — identifying defects, flagging repairs and giving you documented evidence to negotiate with or walk away from.
Clear traffic light ratings, plain-English findings and a surveyor you can actually call. If you’re buying a conventional property and want to go in with your eyes open, this is the survey you need.
What you receive:
Traffic light condition ratings across all major elements
Urgent defects and repair priorities clearly identified
Legal issues flagged for your solicitor
Optional market valuation available
RICS Level 3 Building Survey
Know Exactly What You're Buying Before You Sign
London’s older housing stock hides problems. Subsidence, damp, structural movement, poor extensions — issues that cost tens of thousands to fix and that no mortgage valuation will ever flag. A Level 3 Building Survey uncovers them before you commit.
Every accessible area is inspected in detail. You get repair cost guidance, a clear priority order and a surveyor available to talk you through the report. Not a form. A proper inspection by someone who knows London property.
What you receive:
In-depth report covering all accessible areas including loft and cellar
Defect diagnosis with estimated repair costs
Advice on alterations, extensions and structural concerns
Optional market valuation available

Which Survey Do You Need?
There are two RICS survey levels for residential buyers. The right one depends on the property, not personal preference.
RICS Level 2 Home Survey
A visual inspection of the property’s main elements, rated using the RICS condition system. Suited to modern or conventional homes in reasonable condition. It will identify defects, flag concerns, and tell you where further investigation is needed. If the property is straightforward, a Level 2 is usually the
right starting point.
RICS Level 3 Building Survey
A detailed structural assessment covering the cause, consequence, and recommended action for every defect found. The appropriate survey for older properties, period homes, converted buildings, or anything with visible issues. If you are buying a Victorian or Edwardian property in London, a Level 3 is the standard recommendation, not an upgrade

Need a Valuation Too?
A survey assesses condition. A valuation determines market value. They are separate instructions. If you need both — for mortgage purposes, Help to Buy, shared ownership, or estate reasons — we can arrange a RICS Red Book Valuation alongside your survey. Just let us know when you get in touch.

FAQ
Frequently Asked Questions
Do I really need a survey when buying a house?
Yes, and the mortgage valuation your lender arranges is not a substitute. A mortgage valuation is instructed by the lender to protect their security, not yours. It typically involves a brief inspection or a desktop assessment and will not tell you whether the roof is failing, whether there is structural movement, or whether the drainage is in a state that will cost you thousands after you move in. A residential survey is instructed by you, carried out in detail, and written to give you an accurate picture of what you are buying before you are legally committed to it. Many buyers skip a survey to save a few hundred pounds and then discover far more expensive problems once they have moved in. The survey exists to prevent exactly that.
What is the difference between a Level 2 and Level 3 survey?
A Level 2 Home Survey is a visual inspection. Your surveyor will assess the main elements of the property, assign RICS condition ratings, and flag anything that needs attention or further investigation. It is suitable for modern homes or properties in reasonable condition with no obvious structural concerns. A Level 3 Building Survey goes considerably further. It looks at the structure in detail, explains why defects have occurred, what the likely consequence is if they are left unaddressed, and what action is needed. It is the appropriate survey for older properties, period homes, converted buildings, or any property where the condition is uncertain. The difference in cost between a Level 2 and Level 3 is usually modest. The difference in what they tell you is significant.
I'm buying a Victorian property in London. Which survey do I need?
A Level 3 Building Survey. Victorian and Edwardian properties have specific characteristics that a Level 2 survey is not designed to fully assess. Older construction methods, original materials, previous alterations, and the defect patterns common to period stock all require the detailed investigation that a Level 3 provides. Things like chimney stacks, original timber floors, older roof structures, solid wall construction, and historic damp issues are all areas where a surface-level inspection can miss what a structural assessment would catch. In London, where period property makes up a large proportion of the housing market, a Level 3 is not an optional extra for older homes. It is the standard appropriate instruction.
The survey has flagged issues with the property. What should I do?
Read the condition ratings carefully. A Condition Rating 3 means the issue is serious and requires immediate attention or further specialist investigation before you commit. A Condition Rating 2 means there are defects that need addressing but are not urgent. Not every flagged item is a reason to walk away, but each one is information you can use. If the survey identifies defects with a material repair cost attached, you have a factual basis to renegotiate the agreed price, ask the seller to carry out works before exchange, or request a specialist report before deciding whether to proceed. Your surveyor can help you understand the relative significance of what has been found and, where relevant, give a broad indication of likely repair costs. The survey is not just a document. It is a negotiating tool.
Does a house survey include a valuation?
No. A RICS Level 2 or Level 3 survey is focused entirely on the physical condition of the property. It does not include a formal market valuation as standard. The two are separate instructions that serve different purposes. A survey tells you what state the property is in. A valuation tells you what it is worth. If you need both — for example, because your mortgage lender requires a RICS valuation, or because you are purchasing through Help to Buy or shared ownership — we can arrange a RICS Red Book Valuation alongside your survey. Just mention this when you get in touch and we will confirm what is involved.
How long does a residential survey take, and when will I get the report?
The time spent inspecting the property depends on its size, age, and condition. A Level 2 survey on a standard flat or modern semi-detached house typically takes one to two hours on site. A Level 3 survey on a larger or older property can take three to five hours or more. The written report is usually delivered within three to five working days of the inspection, though timescales can vary depending on complexity. If you are working to a tight deadline because of an exchange date or a chain, tell us when you instruct and we will do what we can to accommodate it.
How much does a residential survey cost and is it worth it?
Survey fees vary depending on the type of survey, the size of the property, and its location. A Level 2 survey will generally cost less than a Level 3. As a rough guide, fees for residential surveys in London typically range from a few hundred pounds for a Level 2 on a smaller property to over a thousand for a Level 3 on a larger or more complex one. Whether it is worth it depends on what it finds. If a survey identifies a defect that costs more to fix than the survey fee, it has already paid for itself. If it identifies something that changes your decision to proceed, it may have saved you considerably more. The more relevant question is what it costs you to buy a property without knowing its condition.
Do I need a survey if I'm buying a flat?
Yes. Flats, particularly those in older converted buildings, can have significant structural, damp, and maintenance issues that are not visible during a viewing. A survey will assess the condition of the fabric of the building as far as it is accessible, identify any defects within the flat itself, and flag concerns about common areas or the wider structure. For converted period buildings in London, a Level 3 survey is often appropriate. For newer purpose-built flats in reasonable condition, a Level 2 may be sufficient. It is also worth reviewing the lease, service charge history, and any planned major works separately, as these can affect the cost and viability of ownership independently of the property’s physical condition.
Do you carry out residential surveys across London?
Yes. We are based in Covent Garden and carry out Level 2 and Level 3 surveys across London and nationally. If you are unsure whether we cover your area, contact us and we will confirm. We also carry out surveys outside London for clients purchasing nationally, so if the property is outside the city, it is still worth getting in touch.
