A property valuation forms the first impression of your sale. The figure provided by your estate agent will establish your asking price, influence the speed at which your property attracts interest and shapes the path for your onward purchase. Preparing for a valuation is not about creating a misleading sense of perfection; rather, it is about removing distractions to enable the agent to assess your property as clearly and accurately as possible.
At John D Wood & Co. we have been valuing London and South East homes for over 150 years, and the difference between a well-prepared property and one that is not can often amount to thousands of pounds. Follow these tips to ensure your valuation delivers the best possible outcome.
What happens during a house valuation?
Your estate agent will typically spend between 30 minutes and an hour inspecting your property, taking time to review each room and assess its condition, layout, natural light, and the quality of key areas such as the kitchen and bathrooms. Above all, they will consider how your home compares to similar properties they have recently valued or sold locally.
This is not the same as an online estimate. Online tools gather information from your postcode and national averages; they cannot account for individual factors such as the need for repairs or the addition of a newly fitted kitchen. An in-person valuation captures these nuances and provides a far more accurate assessment.
Your agent will also ask a series of practical questions, such as whether the property is freehold or leasehold, when the boiler was last serviced, and whether any structural work has been carried out. Preparing this information in advance can help avoid unnecessary follow-up and ensure a more efficient valuation process.
What affects the valuation of your property?
Some of this you can control, some you simply cannot.
Location is the single biggest driver of value. A desirable school catchment, easily accessible transport links, parks and local shops nearby will impact the value of your property. In some areas of London, even the side of the street you live on can change the figure. That is just the way the market works.
Condition is the second major factor.Estate agents are adept at identifying it, and it will be reflected throughout the valuation, from signs of damp and cracked plaster to bathrooms that appear dated. A property that presents as well maintained generally inspires confidence and suggests there are unlikely to be significant issues concealed beneath the surface.
Layout and space have a significant impact on what buyers are willing to pay. In the UK, buyers tend to place greater value on well-proportioned, practical rooms than on total square footage alone. A bright, spacious sitting room that feels comfortable and easy to furnish will command more interest than a room that is technically large on paper but awkwardly shaped, cramped, or lacking in natural light. Ultimately, it is the flow and liveability of the space, rather than the measurements, that drives perceived value.
Comparable sales form the foundation. Your agent will check what similar properties have sold for in recent months, sometimes down to a specific street. If something comparable went for a certain figure three roads away, that becomes the starting point for yours.
Development potential is worth flagging if you have it. Planning permission for an extension or a loft conversion not yet undertaken can increase the value of the property significantly.
How to prepare your home before a valuation
No one expects a show home. However, there is a clear difference between a property that feels comfortably lived in and one where clutter prevents the agent from appreciating the space. Aim to strike the right balance so your home can be viewed clearly and to its full potential.
Declutter and clean. Tidy surfaces, clear floors, vacuumed carpets. Kitchens and bathrooms in particular get very heavily weighted in any valuation, so it is worth putting some effort into these rooms. You do not have to prepare your property for a photo shoot, but it should be clean and tidy so that the rooms feel spacious and the agent can concentrate on the property itself.
Fix the small things. Minor issues such as a leaky tap, a cracked tile, or a loose door handle are often inexpensive and straightforward to fix. Left unattended, however, they can suggest a lack of ongoing maintenance and influence how your property is perceived. Estate agents are quick to pick up on these signals, and they can subtly affect the overall valuation.
Consider a fresh coat of paint. Peeling wallpaper or a bedroom still decorated in your teenager's colour choices from 2012 can drag an impression down. Neutral tones like off-whites and warm greys brighten rooms, make them feel larger, and give the valuer less to mentally subtract from.
Sort out the front of the house. Kerb appeal is not just estate agent speak; it does affect first impressions. Sweep the path, trim the hedge, wash the windows. If your front door has seen better days, a tin of paint costs next to nothing and changes the entire feel of arrival.
Let the light in. Pull all curtains aside and lift every blind. Place lamps on in rooms that tend towards darkness. A bright, airy home photographs better and values higher — two things you want working in your favour.
Have your paperwork to hand. If you have had the roof completed, installed a new boiler, or had an extension built, gather the certificates and receipts together before the appointment. They allow the agent to value improvements that may not be immediately obvious.
How to get a higher house valuation
Presentation helps, but there are more strategic moves you can make.
Invite more than one agent. Getting two or three valuations is standard practice, and it costs nothing. The range of figures tells you something useful about the market, and comparing how agents justify their numbers helps you spot who really knows your area.
Do your own research first. Check what similar properties have sold for recently — Land Registry data is freely available. Coming to the valuation with this knowledge means you can have an informed conversation about price, rather than simply accepting a figure.
Make sure the agent knows about improvements. New kitchen? Rewired electrics? Double glazing? If the receipts and certificates are in a folder ready to go, your agent can factor them in properly. Undocumented improvements carry far less weight.
Do not neglect the garden. Outdoor space in London is as valuable as gold, yet homeowners consistently underestimate the importance of presenting it well. Mow the lawn, tidy the patio, and make sure the back of the property looks as considered as the front.
Questions to ask your estate agent at a valuation
Remember, a valuation is a two-way conversation. You are assessing whether this is the right agent for your sale, not just listening to a number. A few worth asking:
- How did you arrive at this figure, and which comparable sales informed it?
- What does your fee include, and are there any additional charges?
- How would you market this property specifically — beyond the standard portal listing?
- Realistically, how long do you expect it to take to sell in the current market?
- What similar properties have you sold recently, and what did they achieve versus asking price?
Good agents welcome these questions. If yours seems uncomfortable answering them, that in itself tells you something.
Frequently asked questions
Should I clean my house before a valuation?
Yes, but you are not required to hire a professional cleaning company. A well-maintained, clearly presented home allows the estate agent to focus on the property's actual features. Dirty kitchens, messy hallways, and untidy bathrooms create mental deductions, even unconsciously.
What devalues a house valuation?
Deferred maintenance is the main culprit. Visible damp, outdated electrics, a roof in poor condition, or structural cracks will all pull a valuation down. External factors like a busy road past the front or complications with the lease on a leasehold property also have an impact that preparation alone cannot fix.
How long does a house valuation take?
Most in-person valuations take between 30 minutes and an hour, with larger properties or those with significant recent work running slightly longer. You will normally receive the valuation figure within a few days of the visit.
Can I get a valuation without selling?
Of course. Many homeowners want to establish their property's current market value for remortgage purposes, financial planning, or simply to see where they stand. We offer no-obligation valuations for exactly this reason — there is never any pressure to put the property on the market.
