As a rule, open 5–10% below asking on a typical UK home that's priced near the market — but the right opening offer is set by evidence, not a flat percentage. Anchor it to recent comparable sales, how long the property has sat, and how much pressure the seller is under. Below, the four checks that turn a guess into a number you can defend.
As a rule of thumb, you can open 5–10% below asking on a typical UK home that is priced close to the market. But a percentage is a starting point, not an answer. The right opening offer is the one you can defend with evidence: recent comparable sales, how long the property has sat unsold, and how much pressure the seller is under. Get those three right and the number almost sets itself.
Why a flat percentage is the wrong tool
The asking price is not the value of the home — it is the seller's opening position, set with the help of an agent who is paid to market it ambitiously. "Offer 10% below asking" treats every listing as equally priced, which they never are. One home may be pitched 2% over its true value; another, sitting unsold for four months, may be 15% over. Apply the same flat discount to both and you overpay on the first and leave money on the table on the second.
The estate agent speaks in superlatives. Your offer should speak in evidence. That means working from what comparable homes have actually sold for, not from a round number off the asking price.
The four inputs that set your offer
1. Comparable sold prices
Start with what similar nearby homes have sold for — not what they are asking. HM Land Registry Price Paid data and the major portals' sold-price tools show achieved prices. Match on the things that drive value: type, number of bedrooms, floor area, condition and street. Converting to a price per square foot makes unlike homes comparable and gives you a fair-value range rather than a single guess.
2. Days on the market
How long a property has been listed is one of the clearest signals of negotiating room. A home that has sat unsold for months is usually telling you it is priced too high — which strengthens a below-asking offer backed by that fact. Watch for relistings that quietly reset the visible counter; the price history usually reveals the true timeline. We cover this in full in days on the market: why it matters.
3. Seller motivation
A seller under pressure will move further on price. Look for the tells: a price reduction already on the listing, a probate or relocation sale, a property standing empty, or an onward purchase the seller is keen to complete. None of these guarantee a discount, but each shifts the balance toward the buyer. Reading these signals — rather than guessing at them — is the difference between an offer that gets a counter and one that gets ignored.
4. Your strength as a buyer
Price is only half of an offer. Sellers also weigh certainty — and a proceedable buyer who can complete cleanly is worth real money. A mortgage agreement in principle, proof of funds, no chain and flexible timing all let you offer a little lower while still being the most attractive bid on the table.

A worked example: from asking price to fair value
Suppose a three-bed terrace is on at £400,000. Two genuinely comparable homes on the same street sold recently for £372,000 and £368,000. The subject home is around 1,000 sq ft, so those sales work out at roughly £370 per square foot — putting fair value near £370,000, about 7.5% under asking. The listing has been live for eleven weeks with one price cut already. The evidence points to an opening offer in the high £350,000s, with room to settle around £368,000–£372,000.
| Property | Sale / asking price | £ per sq ft | What it tells you |
|---|---|---|---|
| Subject home (asking) | £400,000 | ~£400 | The seller's opening position |
| Comparable A (sold) | £372,000 | ~£372 | Recent, same street |
| Comparable B (sold) | £368,000 | ~£368 | Recent, same street |
| Fair-value range | ~£368k–£372k | ~£370 | Open below it, settle within it |
Notice what the figures do: they convert a vague "is £400k too much?" into a range you can quote to the agent word for word. That is the whole point — every pound you ask the seller to move on should be a pound the evidence already justifies.
Turning the number into an offer ladder
Once you have a fair-value range, plan your moves in advance: an evidence-backed opening offer below the range, one prepared counter that lands inside it, and a firm walk-away line above which the deal stops making sense. Knowing all three before you call the agent stops emotion from setting the price on the day. For how low you can realistically go, see how far below asking price you can offer; for the exact words to use, see how to negotiate house price.
This is exactly what Broc is built to do: pull the sold comparables, read the days-on-market and price-history signals, weigh the seller's likely pressure, and hand you an offer ladder with the justification attached. It is evidence over emotion, turned into a plan. If you first want to sanity-check the asking price itself, start with is the house overpriced?
Work out your number before you make the call
An offer you can explain is an offer you can hold. Gather the comparables, check the days on market, read the seller's position, and price your own strength into the bid — then walk into the negotiation with a figure that does not flinch. Broc can do that legwork for a specific address in minutes, so the only thing left for you is to make the call.

Frequently asked questions
Is it rude to offer below asking?
No — in the UK, offering below asking is routine, and agents expect it. What matters is justifying the number with evidence: comparable sold prices, the property's condition, and how long it has been on the market. A reasoned offer reads as serious, not cheeky.
How much below asking is too low?
There is no fixed limit, but an offer with no supporting comparables risks being dismissed without a counter. Tie any low offer to specifics — condition, time on market, recent comparable sales — so the agent has something concrete to take back to the seller.
Should my first offer be my best offer?
Rarely. Leave room to move up once, so that an accepted second offer still lands at or below the fair value you calculated. Open with a defensible figure below your ceiling, not at it.
