Most market appraisal house valuations carried out by estate agents for homeowners preparing to sell take between 15 and 60 minutes when an estate agent visits in person, though the actual time depends on your property. A compact flat in Fulham and a five-bedroom family house in Richmond will naturally require different levels of property assessment, especially when discussing local markets, comparable sales and pricing strategy. Mortgage valuations follow a different process, with the timeline from instruction to report taking between one and two weeks.
Understanding how each type of property valuation works can help make the entire process clever and easier to plan when preparing to sell. For the purpose of this guide, we are referring to market appraisal valuations rather than formal RICS valuations, which serve a different purpose and are mostly used for legal, financial or surveying needs.
How long does an estate agent valuation take?
This is the valuation that most sellers deal with first. An estate agent market appraisal involves your agent arriving at the property, assessing the overall condition and layout, taking into account any improvements or upgrades, reviews outdoor space where relevant, and compares the property with similar homes that have recently sold nearby.
A standard two- or three-bedroom home usually takes 20 to 40 minutes. Larger properties can take up to an hour, particularly if there are multiple floors, period features or outbuildings to assess. There is considerable variation across London and the South East. For example, a mansion flat in Chelsea requires a different approach to valuing a detached family house in Esher, and the time needed will reflect that.
An important part of the appointment is the discussion around pricing and market positioning. A thorough valuation should include a conversation about how house valuations work, comparable sales in the local area, and the asking price strategy that best suits your circumstances. Depending on the property and the level of advice required, this may add additional time to the appointment.
Your agent will often share an initial figure during the visit itself. A written report with supporting market evidence and pricing guidance will usually follow within a day or two.
How long does a mortgage valuation take?
Mortgage valuations sit in a different category because they relate to a property being purchased rather than sold and are arranged by the lender on behalf of the buyer. This means you do not get to choose the surveyor and their purpose is to confirm that the property provides adequate security for the loan. This differs from a survey, which examines the structural condition in detail.
Unlike a market appraisal valuation, which helps to establish an achievable asking price and selling strategy, a mortgage valuation exists solely for lending purposes. Please note that professional RICS valuations are separate and should not be confused with either.
The physical visit takes 15 to 30 minutes, generally. Some lenders skip it altogether and rely on desktop valuations built from Land Registry data and recent comparable sales. These can be near-instantaneous, but miss things you can only pick up in person.
The overall timeline is usually influenced more by administration and lender processing times than the valuation appointment itself. Booking the surveyor after the lender instructs the valuation can take a few days, and the written report is typically returned to the lender within around five working days. In most cases, it is reasonable to allow one to two weeks between the valuation being instructed and the mortgage offer being issued, although timelines can be longer during busier periods of the year.
A down valuation, where the surveyor values the property below the agreed purchase price, can extend the process further. In these situations, additional discussions may be needed between the buyer, seller and lender before the transaction can move forward.
What affects how long a house valuation takes
There is no single answer, but a handful of factors make the biggest difference:
- Property size and layout. More rooms, more time. This is the straightforward one.
- Unusual or period features. Listed buildings and properties with non-standard construction need closer inspection. The agent or surveyor has to consider elements that do not show up on a floor plan.
- Condition. A well-maintained home is quick to assess. One that clearly needs work generates more notes, more discussion, and a more cautious figure.
- Whether every space is accessible. If the valuer cannot get into the loft, the garage, or a locked room, they cannot include it in their assessment properly. That sometimes leads to a second visit.
- Agent or surveyor availability. In a busy market, it may take a few extra days to secure the appointment itself.
London properties, especially those in prime central areas where individual features can swing value by hundreds of thousands, tend to require more time at the inspection stage.
How to prepare for a house valuation
Your property does not need to be in show-home condition for a valuation. Agents and surveyors are inspecting structure, layout, and potential, not whether your cushions match the curtains.
However, a few things may help the overall process:
- Make sure every room is accessible. Loft hatches, cellars, garden sheds, if the valuer cannot get in, that part of the property goes unassessed. It is frustrating for everyone involved.
- Clear enough clutter that the agent can see walls, floors, and fittings. You do not need to deep-clean, but being able to walk through without stepping over boxes makes the visit faster and more accurate.
- Have your documents ready. Planning permissions for that kitchen extension, the lease if you are in a flat, building regulations certificates, all of these speed things up and help the agent give a more precise figure.
- Think about what you want to ask. The valuation is a two-way conversation. Come prepared with questions about local demand, comparable sales, and whether any improvements might lift the price before you list.
One thing worth doing before you even book the valuation: check whether you have a current Energy Performance Certificate. You need one in place before marketing the property, and arranging it early means one fewer delay between valuation and going live.
What happens after a house valuation?
For estate agent valuations, the written report usually arrives within a few days. It will typically include a suggested asking price supported by comparable market evidence, along with guidance on positioning the property for sale, including marketing recommendations and launch timing. The valuation should provide a clear picture of where the property sits within the current market, although values may need reviewing if market conditions change or the property is not listed for some time.
Mortgage valuation reports are sent directly to the lender rather than the buyer or seller. If everything progresses smoothly, a mortgage offer may follow within a few days to a week. However, issues such as a down valuation, concerns about the property’s condition, or requests for further checks can extend the process while matters are reviewed and resolved.
Once the valuation stage has been completed, the next steps generally involve finalising marketing materials, arranging photography, and agreeing on a launch date for the property. At this point, the sales process becomes more active and preparations for bringing the property to market can begin.
Frequently asked questions
Does my house need to be tidy for a valuation?
Not particularly. The valuer is primarily concerned with the property's layout, condition, and features. How neat you have kept the place is not the main concern, simply having rooms accessible and reasonably tidy will suffice. Presentation becomes more important once viewers begin to arrive.
What happens during a house valuation?
The agent or surveyor moves from room to room, recording condition and features, taking measurements where needed, and comparing the property against recent sales in the area. In an estate agent valuation, there is usually a conversation about pricing strategy and your plans for selling.
What devalues a house valuation?
Repairs are the main factor. Damp, subsidence, a roof approaching end of life, outdated electrics, any of these will pull the figure down. Building work carried out without proper approval, such as extensions or loft conversions, creates problems too, because both buyers and mortgage lenders will flag it.
Is a mortgage valuation the same as a survey?
No. The mortgage valuation confirms that the property is worth the price being offered, primarily for the lender's benefit. A home survey, a Level 2 or Level 3 RICS survey, is an in-depth report on structural condition, carried out for the buyer. It is sensible to commission your own survey even if the mortgage valuation goes through without a hitch.
