How Do You Make an Offer on a House? A UK Guide

You have found the house. Now comes the nerve-wracking part: actually making the offer. It can feel oddly informal, often just a phone call to the estate agent, yet it sets the price of one of the biggest purchases you will ever make. In England, Wales and Northern Ireland the process runs one way, and in Scotland it works quite differently. This guide walks you through making an offer on a house in the UK from start to finish, including how much to offer, how to make yours stand out, and how to protect yourself once it is accepted.

Before you offer: get your position straight

The strongest offers come from buyers who are ready, so a little groundwork first pays off. Sort out a mortgage agreement in principle, which is a lender's indication of how much it would lend you. It signals to the seller that you are serious and able to proceed, and a mortgage advisor can arrange one for you, as covered in our guide on what a mortgage advisor does. Make sure your deposit is in place and you know your true budget, not just the loan but the cash you need on top, which our guide on how much deposit you need sets out. Walking in with your finances lined up turns a hopeful offer into a credible one.

Work out how much to offer

There is no fixed rule, but a sensible offer is grounded in evidence rather than gut feeling. Look at what similar homes nearby have actually sold for, not just their asking prices. Check how long the property has been on the market, since a home that has sat unsold for months gives you more room to offer below asking, while a fresh listing in a busy area may need a full-price or competitive offer. Factor in the wider market too: in a buyer's market you can push lower, while in a seller's market with lots of interest you may need to lead with your best. Decide your opening offer and, just as importantly, your walk-away limit before you pick up the phone.

How to make the offer

In England, Wales and Northern Ireland you make your offer to the estate agent, who is legally obliged to pass every offer on to the seller. The usual sequence is simple:

• Make the offer to the estate agent, normally by phone in the first instance.
• Follow it up in writing or by email, so there is a clear record of what you offered and on what terms.
• State that your offer is "subject to contract" and subject to survey, which keeps it conditional while the checks are done.
• Wait for the seller to respond, accepting, rejecting, or coming back with a counter-offer to negotiate.

Do not be afraid to negotiate. An initial rejection is often the start of a conversation, not the end of it, and going back and forth on price is completely normal.

How to make your offer stand out

Price is not the only thing sellers care about. Certainty and speed matter too, especially in a competitive situation. When you make your offer, mention anything that sets you apart: that you have a mortgage agreement in principle, that you are a first-time buyer or chain-free, that you can be flexible on the completion date, or that you are a cash buyer if that applies. A slightly lower offer from a buyer who can clearly proceed quickly can beat a higher offer from someone whose position looks shaky. Being polite and easy to deal with genuinely helps too, since sellers are choosing a person as much as a number.

What happens once your offer is accepted

When the seller accepts, the property is usually marked Sold Subject to Contract, and you can ask for it to be taken off the market and further viewings cancelled to reduce the risk of being outbid. You may be asked for a small holding deposit, which is normally repayable if the sale does not go ahead. From here the real work begins: you formally apply for your mortgage, instruct a solicitor or licensed conveyancer to handle the legal side, and usually arrange a survey to flag any problems. The crucial point to understand is that in England, Wales and Northern Ireland none of this is legally binding until you exchange contracts. Until that moment, either side can still walk away. Our guide on what exchange of contracts means explains the stage where the deal finally becomes binding.

Gazumping: the risk to be aware of

Because the deal is not binding until exchange, a seller can legally accept a higher offer from someone else even after accepting yours. This is called gazumping, and it is more common than people expect, with research suggesting a large share of buyers have experienced it at least once. If it happens you can lose money already spent on surveys, searches and legal fees. You cannot fully prevent it, but you can reduce the damage by moving quickly to exchange, staying in close contact with the agent, and considering Home Buyers Protection insurance, which helps cover those wasted costs if a purchase collapses through no fault of your own. It is also worth budgeting for the full cost of buying from the outset, which our guide to the hidden costs of buying a home breaks down.

Making an offer in Scotland is different

If you are buying in Scotland, the process changes in important ways. Sellers usually provide a Home Report, including a survey and valuation, before the property is even listed, so much of the checking is done upfront. Offers are submitted formally in writing through a solicitor rather than casually to an agent, and you would normally register a Note of Interest first. Properties are often marketed as "offers over" a set figure, and the seller may set a closing date for sealed bids. Most significantly, once your offer is accepted and the formal letters known as missives are concluded, the deal becomes legally binding far earlier than south of the border, which is why gazumping is rare in Scotland. If you are buying there, your solicitor leads the process from the start.

Putting it all together

Making an offer on a house comes down to being prepared, pricing on evidence, and presenting yourself as a buyer the seller can rely on. Get your mortgage agreement in principle and deposit ready, research what the home is really worth, offer through the agent in writing, and strengthen your bid with your position rather than price alone. Then push to exchange promptly to lock the deal in.
