When searching for a new home in the UK, it’s common to come across listings marked “under offer” or “sold STC (subject to contract).” If you’re interested in a house that carries one of these labels, you might wonder whether it’s still possible to arrange a viewing—or whether you’ve missed your opportunity entirely.
The good news? In many cases, yes, you can still view a property that is under offer. But there are conditions, ethical considerations, risk factors, and regional nuances that buyers should understand before proceeding.
This in‑depth guide explains everything you need to know about viewing a house that is under offer in the UK, how the process works, what estate agents can and can’t do, and how your viewing could impact the sale.
What Does “Under Offer” Mean in UK Property?
In the UK, a property becomes under offer when a seller has accepted an offer from a buyer, but no legally binding contract has been exchanged yet. This means:
- The sale is not final
- The property is still technically available
- The seller may or may not be open to further viewings
- Either party can legally withdraw without penalty
The terms “Under Offer” and “Sold STC” are often used interchangeably by estate agents. Both mean the same thing: the sale is progressing, but nothing is set in stone.
Can You Still View a Property That Is Under Offer?
Yes, you can—unless the seller requests otherwise.
Estate agents are legally allowed to show the home to new prospective buyers unless the seller has given written instructions prohibiting further viewings.
Under the Estate Agents Act 1979, agents must pass on all offers to the seller up until contracts are exchanged.
This means:
- The property remains viewable
- You can submit an offer
- The seller has the right to accept your offer
It’s part of the UK’s non‑binding property process and one of the reasons gazumping still occurs.
Why Would a Seller Allow Viewings on a Property Under Offer?
There are several reasons why sellers keep their homes open to viewings even after accepting an offer:
- The buyer hasn’t provided proof of funds
Sellers get nervous when a buyer can’t show a mortgage in principle or proof of deposit. - The chain is unreliable
A buyer involved in a long or unstable chain carries a higher risk of collapse. - The seller wants to invite higher offers
If the market is hot, sellers may hope for stronger offers and use the “under offer” period to their advantage. - Concerns about the buyer’s commitment
Slow communication, delays with solicitors, or issues with surveys may worry sellers. - The seller simply wants backup buyers
Many UK sellers keep options open until the contract is legally binding.
Is It Ethical to View a Property Under Offer?
This is where UK property etiquette gets complicated.
Viewing a property under offer isn’t illegal—but some consider it ethically questionable, especially if your intention is to outbid the current buyer.
However, it’s worth considering:
- You might be a more qualified buyer
- Your finances may be in better order
- The seller may appreciate a faster or chain‑free purchase
- The existing offer may already be shaky
At the end of the day, until contracts are exchanged, no buyer has legal claim to the property.
What Is Gazumping—and Could You Be Doing It?
Gazumping occurs when a seller accepts a higher or better offer after already agreeing to sell to someone else.
If you view a property under offer and decide to place a bid that is accepted, the first buyer has essentially been gazumped.
Gazumping is:
- Legal in England and Wales
- Common in competitive markets
- Likely to delay the sale if solicitors must restart paperwork
- Frustrating and costly for the original buyer
In Scotland, however, gazumping is less common due to stricter legal safeguards.
Should You View a House That’s Already Under Offer?
It depends on your circumstances and urgency.
You should consider viewing if:
- You love the property
- You’re a strong buyer (cash buyer, chain‑free, or mortgage‑ready)
- The agent suggests the current offer may fall through
- You’re willing to be patient
You might not want to view if:
- You dislike competitive situations
- You want to avoid being part of a bidding war
- You feel ethically uneasy about gazumping
That said, many UK buyers successfully secure homes that were originally under offer.
Questions to Ask the Estate Agent Before Viewing
If you’re thinking of viewing a house under offer, clarify the situation first. Helpful questions include:
- “Is the seller open to additional viewings?”
- “How strong is the current buyer’s position?”
- “Is the current offer above or below the asking price?”
- “Is the property still accepting new offers?”
- “Has a survey already been done?”
- “What’s the seller’s ideal timeline?”
The answers will help you judge whether it’s worthwhile.
Can You Make an Offer on a Property Under Offer?
Absolutely.
The estate agent must legally pass your offer on to the seller unless instructed otherwise.
Your offer might be accepted if:
- You offer a higher price
- You’re chain‑free
- You can move quickly
- Your finances are better organized
- The current sale is dragging
If the seller chooses you over the original buyer, the property status will change back to “Under Offer”—but this time under your name.
Risks of Viewing (and Offering On) Properties Under Offer
While it can be a smart move, there are some risks:
- Emotional disappointment
You might fall in love with a house you never get. - Competition
Other backup buyers may also enter the picture. - Ethical discomfort
Some buyers feel awkward about gazumping situations. - Wasted time
If the current sale progresses smoothly, you may not get a chance. - Price inflation
You could be drawn into a bidding war.
Despite these risks, many homes marked as “under offer” never reach completion—so staying open to them can increase your chances of success.
Can Sellers Change Their Mind After Accepting an Offer?
Yes. In England and Wales, sellers can legally:
- Accept a new offer
- Reject a current offer
- Change their mind entirely
- Take the property off the market
Until contracts are exchanged, nothing is legally binding.
This is why buyers and sellers alike try to keep communication quick and paperwork efficient.
Tips for Buyers Viewing a Property Under Offer
If you’re serious about securing the home:
- Have your paperwork ready
Mortgage in Principle, proof of deposit, and ID. - Communicate your position clearly to the agent
Emphasize if you’re chain‑free or flexible. - Move quickly
Delays reduce your chances. - Make a strong, fair offer
You don’t necessarily need to outbid the current buyer—but be competitive. - Avoid lowball offers
Sellers rarely abandon an existing offer for something weaker.
How Often Do Properties Fall Through in the UK?
It happens more than you might think.
Recent UK property data shows about 1 in 3 sales fall through before exchange.
Reasons include:
- Mortgage issues
- Survey problems
- Chain collapses
- Slow solicitors
- Buyer backing out
This is why viewing a property under offer is often worthwhile—backup buyers are common and sometimes essential.
Final Thoughts: Should You Try Viewing a House That Is Under Offer?
In most cases, yes—it’s still worth viewing.
An “under offer” status doesn’t mean the property is off the market; it simply means someone else has made the first move. With the UK’s flexible, non‑binding system, sellers and estate agents typically welcome back‑up buyers who can strengthen the sale process.
If you’re financially ready, flexible, and genuinely interested in the home, arranging a viewing could put you in a strong position—especially if the current offer is delicate.
Conclusion
While a property under offer might seem unavailable, the reality in the UK housing market is far more fluid. You can still view it, and you can make an offer—whether the seller accepts depends on your position, speed, and circumstances.
