Read the Market First
Your negotiating position depends heavily on whether you're in a buyer's market or a seller's market. In a competitive market with multiple viewings and quick sales, offering below asking price might lose you the property. In a slower market with properties sitting for weeks, sellers are more flexible.
- ▸Days on market: Properties listed for 60+ days without selling signal a motivated seller — check Rightmove's listing history using the price history tab
- ▸Number of viewings: Ask the agent how many viewings there have been. Few viewings means less competition
- ▸Recent sold prices: Check Land Registry data for comparable properties — if similar homes are selling below asking, that's your baseline
- ▸Local supply: More available properties = more negotiating power for buyers
How Much Below Asking Price Should You Offer?
There is no percentage that answers this, and treating one as a rule is how buyers end up either overpaying or losing a house they wanted. Data from NAEA Propertymark consistently shows UK homes sell for 1–5% below their initial asking price on average, and in slower markets that gap widens — but that is a description of what happened across thousands of unrelated sales, not a discount you can claim on this one.
Work the other way round. Establish what this property is worth from comparable sold prices, then offer that. Sometimes the evidence lands below asking, sometimes at it, and on a well-priced house in a competitive area it may land above. The percentage is an output of the evidence, never the input.
Start by establishing what the property is actually worth based on comparables — not just what the seller wants. If the asking price looks stretched compared to recent comparable sales, that gap justifies a lower offer.
Strengthen Your Position Before Offering
Your offer is more attractive if the seller views you as a reliable buyer. Being in a strong position means: no chain (you're not waiting to sell your own home), mortgage in principle already arranged, and a conveyancing solicitor identified and ready to instruct.
Cash buyers are at the top of the hierarchy, followed by chain-free mortgage buyers, then people with short chains. A seller who has already found their next property and is waiting to exchange will weight certainty of completion very heavily.
- ▸Get a Mortgage in Principle: Shows you can actually afford the property and can proceed quickly
- ▸Identify a solicitor: Have a conveyancer ready to instruct the moment your offer is accepted
- ▸Be chain-free if possible: If you're renting or your current home is already under offer, emphasise this
- ▸Be flexible on dates: If the seller needs extra time to move, accommodating that has real value
Making the Offer
Offers in England and Wales are made through the estate agent and are not legally binding until exchange of contracts. This means you can walk away after an offer is accepted — but so can the seller. That said, gazumping (a seller accepting a higher late offer) and gazundering (a buyer lowering their offer before exchange) both do happen.
When making an offer, don't just state a number. State your position: 'I'm a first-time buyer with a mortgage in principle from [lender], no chain, and a solicitor ready to instruct. I'm offering £X.' This gives the agent something concrete to relay.
Using Survey Results to Renegotiate
A survey carried out after your offer is accepted can reveal issues that weren't visible during viewings — roof defects, damp, structural movement, Japanese knotweed. These give you legitimate grounds to renegotiate, and sellers generally expect this.
The key is to quantify the cost of remedying the issues found. Get quotes from relevant tradespeople, then go back to the agent with a revised offer that reflects those costs. Most sellers will prefer a modest price reduction to the deal falling through and relisting.
When to Walk Away
Negotiation only works while both parties still want a deal. If a seller is completely unmovable on a price that doesn't reflect the property's value or condition, walking away is a legitimate strategy — and sometimes results in the seller coming back to you.
More importantly, don't let sunk costs — survey fees, solicitor searches — push you into completing a purchase that no longer makes sense at the agreed price. Losing £800 in fees is far better than overpaying by £15,000 on a property.
Frequently Asked Questions
How much below asking price should I offer? There is no percentage that answers this — the number comes out of the evidence, not out of a rule. Anchor on comparable sold prices, adjust for condition and any work needed, and offer what that supports. Our guide on working out whether a house is overpriced covers the arithmetic in full; what matters for the negotiation itself is that you attach the reasoning to the number, because an agent has to justify your offer to their client and comparables give them something to work with.
Is it rude to offer below the asking price? No — making an evidence-based offer below asking is standard practice in the UK property market. The asking price is a starting point, not a legal entitlement. What matters is how you frame it: reference comparable sales, highlight any issues or survey findings, and be respectful in tone.
What is a lock-in agreement and does it help? A lock-in (or exclusivity) agreement involves the seller agreeing not to accept other offers for a set period in exchange for the buyer bearing more costs upfront (survey, searches). They are not legally binding on the sale itself but signal commitment. They are used in some commercial transactions and high-value residential sales.
Can I renegotiate after a survey finds problems? Yes — this is one of the most legitimate reasons to return to negotiation after offer acceptance. Commission repair quotes from qualified tradespeople, share them with the agent, and make a specific price reduction request backed by evidence. Sellers can say no, but most expect post-survey negotiation on substantive issues.
Should I offer on a property I haven't viewed in person? Avoid making a firm offer without a physical visit. Virtual tours and photos are curated by the seller. In-person viewing reveals noise, smells, natural light, street feel, and neighbour situations that no online listing captures. For investment properties at distance, at minimum commission a local property sourcer or agent to view on your behalf.
