Best and Final Offers: How Sealed Bids Work in the UK

Quick answer

"Best and final offers" means the agent has more than one interested buyer and wants each to submit their highest offer by a deadline. You normally get one shot, without seeing the other bids. The seller then picks the offer they prefer — which isn't always the highest.

How the process usually works

1. The agent tells interested buyers there are multiple offers.
2. A deadline is set, often a specific day and time.
3. Each buyer submits one written offer, with their position.
4. The seller reviews the offers with the agent and chooses one.

Sometimes it's called a "sealed bid" process. It's less formal than an auction and nothing is binding until exchange.

What sellers actually look at

• Price — obviously important, but not everything.
• Chain position — chain-free and first-time buyers are attractive.
• Finance — cash, or a mortgage agreement in principle with a deposit in place.
• Timescales — whether you can match the seller's plans.
• Conditions — fewer conditions usually look stronger.

How to decide your figure

Don't let the process push you into a number you can't justify.

1. Check comparable sold prices — what have similar homes nearby actually sold for? Our guide to finding comparable sold prices shows how.
2. Check £/sq ft against the local average — see how to work out price per square foot.
3. Think about the mortgage valuation. If you bid well above the evidence, your lender may value it lower and you'll need to cover the gap.
4. Pick an uneven number. £352,750 can edge out a round £350,000 when offers are close.
5. Write down your walk-away figure and stick to it.

If your evidence suggests the asking price is already at the top of the range, it may make sense to bid at asking rather than above it. For when going over can be justified, read when to offer above asking price.

What about escalation clauses?

Some buyers offer "£5,000 above the highest bid up to £X". These are rarely used in the UK and many agents won't accept them. A single, clear figure is usually safer.

Bid with evidence, not adrenaline

An Offer Smart report pulls together comparable sales, £/sq ft and a suggested offer range in minutes — ideal when a best-and-final deadline is tomorrow.
