Mortgage Valuation (2026): Timeline, What They Check & Down Valuations
A mortgage valuation isn’t a survey for you — it’s a quick check for the lender to confirm the property is worth what you’re paying. Most cases sail through, but a down valuation can throw a purchase off course. Here’s what happens at each stage, how long the offer takes afterwards, and exactly what to do if it comes back low.
Quick Answer
A mortgage valuation is an assessment the lender arranges to confirm the property you’re buying is worth roughly what you’ve agreed to pay — so they know their loan is secure. It’s not a survey for your benefit: it’s brief (often 15–45 minutes on site, or done remotely), and you may never even see the report. Its job is to confirm the lender’s loan-to-value.
After the valuation, a formal mortgage offer typically arrives within 2–4 weeks, though it isn’t guaranteed — underwriting runs alongside and can still raise questions. The big risk is a down valuation (the property valued below your agreed price), which affects roughly 1 in 5 applications and leaves a shortfall you’ll need to resolve. The good news: a down valuation rarely ends a purchase — there are five clear options, and switching to a lender that uses a different surveyor is often the fix. Your home may be repossessed if you do not keep up repayments on your mortgage.

What Is a Mortgage Valuation?
A mortgage valuation is a property assessment carried out for your mortgage lender to confirm the home you’re buying (or remortgaging) is worth what you’ve agreed to pay. From that figure, the lender calculates your loan-to-value ratio — the size of the loan relative to the property’s value — which underpins how much they’ll lend and at what rate.
The crucial thing to understand from the outset: this valuation is for the lender, not for you. It protects their security, confirming they’re not lending more than the property is worth. It’s carried out by a surveyor on the lender’s panel, and depending on the lender you may or may not receive a copy of the report. It typically happens after you’ve submitted your full mortgage application (not to be confused with the earlier agreement in principle, which comes before you’ve found a property), and it’s one of the final steps before a formal offer.
Mortgage Valuation vs Survey — a Costly Thing to Confuse
This is the single most important distinction on this page, because getting it wrong can cost you thousands. A mortgage valuation and a property survey are completely different things:
Mortgage valuation (for the lender)
Confirms the property is worth the loan amount. Brief, often free, arranged by the lender. Does not assess condition in any depth or flag defects you’d want to know about. You may never see it.
Survey (for you, the buyer)
A HomeBuyer Report (£400–£800) or Building Survey (£600–£1,500) that inspects condition, flags defects, damp, structural issues — protecting you and enabling price renegotiation. Optional but strongly advised.
Don’t rely on the valuation to spot problems
A mortgage valuation is not designed to highlight defects — it can pass a property that has damp, dodgy wiring or structural issues, because that’s not its job. Buyers who skip a proper survey because “the valuation was fine” can inherit expensive surprises. The valuation protects the lender’s money; only a survey protects yours. Budget for one, especially on older or non-standard properties.
What Does a Mortgage Valuation Look For?
The surveyor is answering the lender’s questions, not compiling a defect list. They typically assess:
- Market value — what the property is realistically worth, using comparable recent sales in the area.
- Obvious risks to the security — significant structural problems, subsidence, damp or disrepair serious enough to affect value or lendability.
- Construction type — standard brick-and-tile is straightforward; non-standard construction (concrete, timber-frame, high-rise) can limit lending.
- Tenure issues — a short lease, unclear title or boundary disputes can all flag concerns.
- Whether the property is suitable security — essentially, could the lender recover their money if they had to repossess and sell.
If the surveyor flags something, the lender may reduce the loan, add conditions (e.g. require repairs or a specialist report), or in some cases decline. That’s why anything unusual about a property — or your own circumstances — is worth flagging to a broker early, so you’re matched to a lender comfortable with it.
Types of Valuation & How Long It Takes
Not every valuation involves someone visiting the property. There are three main types, and which one your lender uses affects the timeline enormously:
| Type | What happens | Speed |
|---|---|---|
| Physical valuation | A surveyor visits and inspects the property in person (~15–45 minutes on site). | Report to lender within a few days. |
| Desktop valuation | No visit — the surveyor values remotely using data and comparable sales. | Often 24–48 hours. |
| Automated (AVM) | Algorithm-based, using Land Registry and property databases. | Near-instant; low-risk cases. |
Desktop and automated valuations are much faster and have become common since 2020, but lenders typically only use them for lower-LTV applications (usually below 75%) on standard-construction homes in areas with plenty of sales data. A bigger deposit can therefore mean a faster, smoother valuation — one of several quiet advantages of a lower LTV, alongside better rates (see our guide to how much you can borrow).
What Happens After the Valuation? The Timeline to Offer
Once the valuation is done, here’s the sequence — and roughly how long each part takes:
- The surveyor sends the report to your lender (a few days for a physical valuation; 24–48 hours for desktop/AVM).
- The lender reviews it alongside underwriting — your income, credit and documents are assessed in parallel, not after.
- A formal mortgage offer is issued — typically 2–4 weeks after the valuation, and sometimes faster for straightforward cases.
- You forward the offer to your solicitor, who progresses the legal work toward exchange and completion.
Don’t wait passively — keep it moving
The gap between valuation and offer is where avoidable delays creep in. Respond to any lender document request immediately, chase your solicitor to confirm searches are ordered, and check your application status via the lender’s portal or your broker. Complex or non-standard properties (listed buildings, unusual construction, buy-to-let) naturally take longer than a standard flat or house. A broker chasing the lender on your behalf often shaves days off this stage.
Is a Mortgage Valuation a Good Sign?
It’s a positive step, but not a guarantee — and it’s worth being clear-eyed about this, because a lot of anxious buyers over-read it. A lender arranging and paying for a valuation means your application has progressed past the initial checks, which is encouraging. But the valuation and the underwriting run partly in parallel, so a satisfactory valuation doesn’t mean the mortgage is approved: the lender can still decline over creditworthiness, affordability or documentation issues that surface separately.
So: a valuation being booked or completed is good news worth taking as momentum — but keep your foot off the celebrations until the formal mortgage offer lands. That’s the document that actually confirms the lender will lend. Until then, don’t take on new credit, change jobs if you can avoid it, or do anything that could disturb the picture your application was based on.
Down Valuation: What to Do If It Comes Back Lower Than Your Offer
This is the outcome everyone dreads, and it’s more common than you’d think — a down valuation affects roughly 1 in 5 applications. It happens when the lender’s surveyor values the property below your agreed purchase price. Because a lender lends against the lower of the price or the valuation, this leaves a shortfall you must resolve before the purchase can proceed.
How a down valuation hits you — worked example
You agree to buy at £350,000 but the valuation comes back at £330,000. On a 90% LTV mortgage, the lender now lends 90% of £330,000 (£297,000) instead of 90% of £350,000 (£315,000) — an £18,000 shortfall you must find on top of your original deposit. The valuation also pushes your effective LTV up, which can affect your rate too.
The important message: a down valuation rarely means the purchase is dead. You have five realistic options:
| Option | How it works |
|---|---|
| Renegotiate the price | Show the seller the lender’s valuation and ask them to reduce to match. The most common fix — many sellers agree rather than lose the sale and restart. |
| Meet in the middle | Split the gap — e.g. on a £20,000 shortfall, you add £10,000 and the seller drops £10,000. |
| Increase your deposit | Cover the shortfall from savings and proceed at the agreed price — simplest if you have the funds. |
| Challenge the valuation | Submit evidence of comparable higher sales. Appeals take ~5–15 working days but rarely succeed unless the valuation clearly missed comparables. An independent RICS revaluation costs ~£250–£500. |
| Switch lender | A different lender uses a different surveyor, who may value higher. Often the most effective route — and exactly where a broker adds value. |
The broker’s edge on a down valuation
Here’s what most buyers don’t know: different lenders use different surveyors, and a whole-of-market broker knows which lender uses which. If you’ve been down-valued, rather than gambling on an appeal (which usually fails), a broker can re-place your application with a lender whose surveyor may value the property fairly — potentially saving the purchase without you finding a penny more. That’s a genuinely practical reason to have a broker in your corner the moment a valuation disappoints.
Mortgage Valuation Fees
Valuation costs vary by lender and property value, but the headline is reassuring: many lenders offer the basic mortgage valuation free, particularly on purchase and remortgage deals designed to attract borrowers. Where a fee applies, it usually scales with property value — from around £100 up to several hundred pounds for higher-value homes. A few things worth knowing:
- Free valuations are a genuine incentive — when comparing deals, a “free valuation” (and free legals on remortgages) can offset a slightly higher rate. This is part of the true cost of a mortgage, not just the headline rate.
- The valuation fee is separate from your own optional survey (the HomeBuyer or Building Survey you pay for privately).
- Don’t choose a deal on the valuation fee alone — it’s a small piece of the overall cost picture. Rate, arrangement fee and term matter far more.

The bottom line
A mortgage valuation is a quick, often free check for the lender — confirming the property is worth the loan, not protecting you (that’s what a survey does). Expect your formal offer 2–4 weeks afterwards, but treat it as momentum rather than a guarantee, since underwriting runs alongside. If you’re hit with a down valuation, don’t panic: renegotiate, bridge the gap, or — often best — switch to a lender whose surveyor values it fairly. That last move is exactly what a good broker does, which is why the valuation stage is a smart moment to have one.

Frequently Asked Questions
What is a mortgage valuation?
A mortgage valuation is an assessment the lender arranges to confirm the property you’re buying or remortgaging is worth roughly what you’ve agreed to pay, so they know their loan is secure. From that figure they calculate your loan-to-value ratio. It’s carried out for the lender’s benefit, not yours — it’s brief, sometimes free, and you may not even receive a copy of the report. It isn’t a survey and doesn’t assess the property’s condition in depth.
Is a mortgage valuation the same as a survey?
No — they’re completely different. A mortgage valuation is a brief check for the lender to confirm the property is worth the loan amount, and it doesn’t flag defects. A survey, such as a HomeBuyer Report (£400–£800) or Building Survey (£600–£1,500), is for you: it inspects the property’s condition, identifies problems like damp or structural issues, and can support price renegotiation. Relying on the valuation instead of a survey can leave you with expensive surprises.
How long does a mortgage valuation take, and how long until the offer?
A physical valuation takes around 15–45 minutes on site, with the report reaching the lender within a few days; desktop and automated valuations often complete within 24–48 hours. After the valuation, a formal mortgage offer typically arrives within 2–4 weeks, though straightforward cases can be quicker and complex or non-standard properties slower. Responding promptly to lender requests and chasing your solicitor helps avoid delays.
Is a mortgage valuation a good sign?
It’s a positive step but not a guarantee. A lender arranging a valuation means your application has progressed past the initial checks, which is encouraging. However, the valuation and underwriting run partly in parallel, so a satisfactory valuation doesn’t mean approval — the lender can still decline over creditworthiness, affordability or documentation. Treat it as momentum, but wait for the formal mortgage offer before considering the mortgage secured.
What happens if my mortgage valuation is lower than my offer?
This is a down valuation, and it affects roughly 1 in 5 applications. Because the lender lends against the lower of the price or valuation, you’ll face a shortfall. You have five options: renegotiate the price with the seller, meet in the middle, increase your deposit to cover the gap, challenge the valuation with evidence of comparable sales (which rarely succeeds), or switch to a different lender whose surveyor may value it higher. A broker can help identify the best route, often by re-placing your mortgage.
How much does a mortgage valuation cost?
Many lenders offer the basic mortgage valuation free, particularly on purchase and remortgage deals. Where a fee applies, it usually scales with the property value, from around £100 up to several hundred pounds for higher-value homes. This is separate from any survey you arrange privately for your own protection. When comparing mortgage deals, a free valuation can offset a slightly higher rate, so factor it into the overall cost rather than the headline rate alone.
At what stage is a mortgage valuation done?
The valuation usually takes place after you’ve submitted your full mortgage application and the lender has carried out its initial assessment — it’s one of the final steps before a formal offer. It’s different from the agreement in principle, which happens earlier, before you’ve found a property. The lender typically arranges the valuation within a few days of processing your application, and the formal offer follows once the report and underwriting are complete.
