Negotiating a house price is mostly about what you say to the agent and when. Lead with evidence, make the agent carry your reasoning to the seller, and always pair a number with a justification. Here are seven scripts — for the opening offer, the counter, the "best and final", and the walk-away — you can use verbatim.
Negotiating a house price is mostly about what you say to the agent and when you say it. Lead with evidence, make the agent carry your reasoning back to the seller, and never quote a number without a justification attached. Below are seven scripts — for the opening offer, the counter, the "best and final" and the walk-away — that you can use almost word for word.
First, remember who the agent works for
The estate agent is paid by the seller and works to get the seller the best price. That is not a reason to distrust them — it is a reason to use them. The agent is the messenger who will repeat your offer to the seller, so your job is to hand them a message worth repeating: a number with a clean, factual reason behind it. The estate agent speaks in superlatives; you speak in evidence, and let them carry it.
If you have not yet set that ceiling, work it out first — our guide to how much to offer on a house walks through turning comparables into a fair-value range and a firm walk-away line, so that your "best and final" is a calculation rather than a guess.

Broc pulls the comps, reduction history and seller signals automatically — and gives you opening, target and walk-away numbers.
Why evidence beats pressure every time
Every script above shares one structure: a number, followed by a reason the agent can repeat. That structure does two things. It gives the seller a factual basis to say yes, and it protects you from negotiating against your own emotions. When you have decided your figures in advance — opening offer, counter and walk-away — the agent's lines about interest and best-and-finals lose their grip. You are no longer guessing; you are holding a position.
How Broc scripts this for you
Writing these lines from scratch under pressure is hard, which is why Broc does it for a specific address. It reads the comparables, days on market and seller-pressure signals, then produces the actual words to use — the opening offer with its justification, the counter, and the walk-away — so you can negotiate from evidence rather than nerve. Once your offer lands, the next stage matters just as much: see offer accepted — what happens next for the steps that keep the deal on track.
If you are weighing a deliberately low opener, read what is a 'cheeky offer' — and when does it work before you use Script 1, so the number you anchor to is one the evidence can carry.
Decide your three numbers, rehearse the lines, and let the agent do the carrying. Negotiation stops being a contest of nerve and becomes a conversation about facts — which is exactly the kind you can win calmly.

Frequently asked questions
What should I say when making an offer?
State the number, then the reason in one breath: "£X, based on [comparable sale] and [time on market]." Give the agent something concrete to repeat to the seller. A bare number invites a reflexive rejection; a number with a reason invites a counter.
How do I respond to "best and final"?
Submit your evidence-based ceiling — the most the property is worth to you — not an emotional jump. Decide that figure before the deadline, in writing. If your ceiling loses, it was the right price to lose at, because going higher would have meant overpaying.
Can I negotiate after a survey?
Yes. A survey that finds real defects is a legitimate basis to renegotiate. Quote the remediation costs from the report or a builder's quote, and ask for a reduction or for the work to be done before exchange. This is renegotiation on evidence, not cold feet.
