Buying a house: the complete step-by-step process explained

Buying a house means moving through six stages in order: saving your deposit and getting a mortgage in principle, finding a property and making an offer, applying for your mortgage, instructing a conveyancer for searches and contracts, exchanging contracts, and completing on moving day. Each stage has its own paperwork, waiting periods and costs, but the sequence rarely changes.

• Save your deposit and get a mortgage in principle
• Find a property, view it and make an offer
• Apply for your mortgage once your offer is accepted
• Instruct a conveyancer to run searches and check contracts
• Exchange contracts, which makes the sale legally binding
• Complete, collect your keys and move in

Buying a home typically takes several months on average in the UK, though that figure stretches considerably if you're buying leasehold or stuck in a long chain. A cash buyer with no chain can sometimes finish in half that time. A first-time buyer in a straightforward freehold purchase, with no one to wait on above or below them, tends to sit closer to the average.

Key Takeaways

Buying a house in the UK follows six fixed stages, from mortgage in principle to completion, and typically takes several months, longer with a chain or leasehold property.

What is the process of buying a house, stage by stage?

The process of buying a house follows a fixed order because each stage depends on the one before it. You can't exchange contracts before your searches come back clean, and you can't get a full mortgage offer before a lender has valued the property. Understanding the sequence is what lets you spot delays before they happen rather than after.

Here's the timeline in the order it actually unfolds, with realistic duration ranges for each stage:

• Mortgage in principle: same day to 48 hours, ideally sorted before you start viewing
• Property search and viewings: anywhere from a few weeks to several months, entirely dependent on the market and your criteria
• Offer to accepted offer: instant once agreed, but negotiations can run days or weeks
• Full mortgage application to formal offer: 2 to 6 weeks, longer if your income is complex
• Conveyancing (searches, contracts, enquiries): typically 8 to 12 weeks
• Exchange to completion: anywhere from same-day to 4 weeks, by agreement between both sides

Rightmove's House Price Index data indicates the average time to find a buyer can be several weeks, which tells you the search phase alone often takes longer than every legal stage combined. Add conveyancing and mortgage underwriting on top, and a seven-month total from first viewing to keys in hand isn't unusual for buyers who aren't in a rush.

Leasehold purchases add time because your conveyancer has to review the lease terms, service charge accounts and any management company correspondence. Regional variation matters too. Local authorities in high-demand areas often have longer search backlogs, which pushes out your conveyancing timeline regardless of how efficient your solicitor is.

If you're chain-free, cash-buying, or purchasing a new build with a motivated developer, you can often complete in 8 to 10 weeks. If you're in a chain of three or four transactions, each depending on the next, four to six months from offer to completion is realistic, and longer is common.

Prepare your finances: deposit, affordability and hidden costs

Lenders look at four things before they'll approve a mortgage: how much deposit you're putting down, your income, your regular outgoings and your credit history. They'll also run an affordability stress test to check you could still cover repayments if interest rates rose. Weak spots in any of these four areas are the single biggest reason mortgage applications stall or get declined outright.

Gather your paperwork before you start looking at properties, not after you've had an offer accepted. That's the point at which delays cost you the most, because sellers and agents start asking why your side is slow.

Documents to have ready:

• Three to six months of payslips (or accounts if self-employed)
• Bank statements covering the last three to six months
• Photo ID (passport or driving licence)
• Proof of address (utility bill or council tax statement)
• Evidence of your deposit source, including a gift letter if family are contributing
• Two to three years of accounts or tax returns if you're self-employed or contracting

Buying a house costs considerably more than the purchase price alone. On a £250,000 property, a first-time buyer might reasonably budget: £500 to £1,500 for a survey, £250 to £450 for local authority and other searches, £800 to £1,700 in conveyancing fees, and Stamp Duty depending on your buyer status and the property's location and price. Add moving costs, and your total extra spend beyond the deposit often amounts to several thousand pounds for a typical first-time purchase.

Pro Tip: Lenders often look more favourably on applicants who've kept their credit utilisation low and avoided new credit applications in the six months before applying. If you're planning to buy within the year, hold off on new credit cards, car finance or even a new mobile contract with a credit check attached.

If you're self-employed or your income is irregular, expect lenders to ask for more evidence, not less. Most want two to three years of accounts, and some will average your income across that period rather than taking your best year. A specialist mortgage broker who works regularly with contractors and self-employed applicants can make a real difference here, since they know which lenders are genuinely flexible on this point.

Finding a property and making an offer: what actually happens

Viewings are where most buyers focus on the wrong things. Décor and staging are the easiest problems to fix after you move in. Structural issues, damp and boundary disputes are the ones that cost money and cause arguments later.

What to check and photograph at every viewing:

• Signs of damp: dark patches on walls, a musty smell, bubbling paint or plaster
• Roof condition visible from outside, including missing or slipped tiles
• Window and door frames for rot, draughts or condensation between panes
• Cracks in walls, particularly around door frames and where extensions meet the original structure
• Water pressure and heating system age (ask when the boiler was last serviced)
• Mobile signal and broadband availability, which agents rarely mention unprompted

Questions worth asking the seller or agent directly:

1. Is the property freehold or leasehold, and if leasehold, how many years remain? 2. Why is the seller moving, and how long have they owned it? 3. Have there been any extensions, conversions or major works, and do they have building regulations sign-off? 4. Are there any ongoing disputes with neighbours, particularly over boundaries? 5. What's included in the sale (fixtures, fittings, white goods)?

Once your offer is accepted, it isn't legally binding. Nothing is binding on either side until contracts exchange, which means a seller can still accept a higher offer from someone else, a practice known as gazumping. It's not common, but it's a real risk in a rising market, and it's precisely why speed matters once your offer is accepted.

The best protection against gazumping is momentum: instruct your conveyancer that day, get your mortgage application moving immediately, and push for a quick survey slot. Some buyers also ask sellers to take the property off the market as a goodwill gesture, though there's no legal way to force this in England and Wales.

How does the mortgage application process actually work?

A mortgage in principle, sometimes called an Agreement in Principle, is a lender's indication of how much they'd likely lend you based on a soft credit check and some basic financial details. It isn't a guarantee, but it tells estate agents you're a serious buyer, and most agents won't put forward an offer without one. Get one before you start viewing seriously, since it also confirms your realistic budget before you fall for a property above it.

Once your offer is accepted, the full mortgage application begins. This is a different, more thorough process:

• You submit full documentation (income, outgoings, ID, deposit proof)
• The lender instructs a valuation of the property
• Underwriters assess the application in detail, which is usually the slowest part
• The lender issues a formal mortgage offer, typically valid for three to six months

Underwriting alone commonly takes two to four weeks, longer if your income is complex or the lender is dealing with a high volume of applications.

A lender's valuation confirms the property is worth what you're paying, purely for the lender's own security. It does not check the roof, the wiring or the drains, and it is not a substitute for an independent survey.

This distinction catches out more first-time buyers than almost anything else in the process. The valuation protects the bank's interests, not yours. If you want to know the actual condition of the property you're buying, you need to commission your own survey separately, at your own cost.

Documents your lender will typically request:

• Payslips or self-employed accounts
• Bank statements
• Proof of deposit and its source
• Details of any other debts or credit commitments
• ID and proof of address

Pro Tip: Never rely on the mortgage valuation as your safety check. Book an independent survey the same week your offer is accepted, so any issues surface while you still have room to negotiate or, if necessary, walk away.

What does a conveyancer do during a house purchase?

Instruct your conveyancer the moment your offer is accepted, not after your mortgage offer arrives. Early instruction means your client care pack, ID checks and payment on account are already done by the time the legal work needs to start, which saves real time later. Delaying this single step is one of the most common, and most avoidable, causes of a slow purchase.

Your solicitor or licensed conveyancer must be regulated, either by the Solicitors Regulation Authority (SRA) or the Council for Licensed Conveyancers (CLC). That regulation matters because it gives you a formal complaints route and professional indemnity cover if something goes wrong.

The conveyancing process, in order:

1. Memorandum of sale issued by the estate agent, confirming the agreed price and both parties' solicitors 2. Your conveyancer requests the draft contract and title documents from the seller's solicitor 3. Searches are ordered (local authority, environmental, drainage, and others depending on the property) 4. Your conveyancer raises enquiries based on the contract, title and search results 5. A report on title is prepared, summarising everything for you before you commit 6. Exchange of contracts, at which point the sale becomes legally binding 7. Completion, when money transfers and you get the keys

A practical conveyancing timetable often runs a few months for a straightforward freehold purchase, with searches and enquiries typically eating up the middle third of that window.

Key searches your conveyancer will run:

• Local authority search: planning history, road adoption status, enforcement notices
• Environmental search: flood risk, contaminated land, subsidence risk
• Drainage and water search: confirms how the property connects to public sewers and mains water

Search turnaround varies enormously by council, from as little as two weeks in efficient authorities to eight weeks or more in busy ones. This is often the single biggest wildcard in your entire timeline, and one you have almost no control over once it's submitted. Some conveyancers use personal search agents rather than waiting on official council searches, which can shave real time off this stage, though it's not accepted by every lender.

Exchange and completion are legally distinct, and the gap between them matters. At exchange, both parties sign identical contracts, deposits are paid, and the transaction becomes binding, pulling out after this point carries serious financial penalties. Completion is when the remaining money moves and you legally take ownership, often on the same day as exchange but sometimes days or weeks later by agreement.

What survey should you get, and what if it finds problems?

A mortgage valuation and a home survey are not the same thing, and confusing them is one of the costliest mistakes a first-time buyer can make. The valuation protects the lender's loan. A survey protects you.

The three main survey types:

1. Condition report: the most basic, flags major issues without much detail, suited to newer standard properties 2. HomeBuyer report: a step up, covering structural condition, damp, and visible defects, suited to most standard homes 3. Full structural (building) survey: the most detailed, recommended for older, unusual or clearly altered properties

Surveys turn up problems more often than most buyers expect. Damp, ageing roofs, subsidence-related cracking and outdated electrics are the most frequent findings, and none of them are automatically deal breakers.

Once a survey flags a problem, you have a decision to make:

1. Negotiate the price down to reflect the cost of remedial work 2. Ask the seller to fix it before exchange, with proof the work's been done 3. Request indemnity insurance for certain legal issues, such as missing building regulations certificates 4. Withdraw if the problem is serious enough that no adjustment feels acceptable

The right choice depends on scale. A damp patch that needs a £300 repair is a negotiating point, not a reason to walk away. Structural movement that needs underpinning is a different conversation entirely, and one worth raising with your conveyancer before you decide anything.

What does buying a house actually cost, including Stamp Duty?

Budgeting for a house purchase means separating the costs that scale with property price from the costs that stay roughly fixed regardless of what you're buying.

Stamp Duty Land Tax is calculated in bands, and your buyer status changes what you actually owe. A first-time buyer benefits from relief on the lowest band up to a set threshold, while a second-home buyer pays a surcharge on top of the standard rates. Because these thresholds and rates change periodically, check the current Stamp Duty rates before relying on any figure, and treat the examples below as illustrative rather than fixed.

Working through the full costs involved in buying a home before you make an offer means no surprises land on you mid-purchase.

Less obvious costs to budget for:

• Leasehold premium or ground rent adjustments at completion
• Buildings insurance, which most lenders require from exchange
• Removal costs, which scale with distance and volume, not just property size
• Snagging or minor repair costs immediately after moving in

How do you choose the right conveyancer or solicitor?

Choosing your conveyancer is one decision most buyers rush, and it's the one that determines how smoothly the rest of the process runs. Ask direct questions before you commit: How long will searches realistically take with this firm? What's included in the quoted fee, and what counts as an extra disbursement? Who handles my file day to day, and how quickly do they respond to queries? Have they handled leasehold or new build transactions recently, if that applies to you?

Watch for a few clear warning signs. A quote with no itemised breakdown of disbursements almost always means hidden extras appear later. Slow or vague responses before you've even instructed them are a preview of how they'll communicate once you're mid-transaction. And a firm that can't tell you roughly how long their searches take with your specific local authority probably hasn't done many in your area.

Fixed-fee, vetted conveyancers solve the cost-uncertainty problem directly. Knowing your legal fee upfront, rather than discovering extras at completion, removes one of the biggest sources of buyer anxiety in the entire process. It's worth asking a real estate lawyer these questions before you sign anything, even if the answers seem obvious.

Pro Tip: Ask specifically whether your conveyancer uses personal search providers or waits on official council searches. The answer can change your timeline by weeks.

What causes conveyancing delays, and how do you avoid them?

Most delays trace back to a handful of repeat offenders: slow replies from the seller's side, local authority search backlogs, problems surfacing from the survey, and mortgage underwriting taking longer than expected. None of these are entirely within your control, but you can reduce your exposure to all of them.

Five actions that genuinely speed things up:

1. Instruct your conveyancer the day your offer is accepted, not after your mortgage offer arrives 2. Get every document on your checklist ready before you're asked for it, not after 3. Book your survey immediately, so problems surface with time to negotiate 4. Follow up proactively rather than waiting for updates to arrive unprompted 5. Ask upfront whether personal searches can be used instead of waiting on the council

Leasehold purchases and long chains are the two factors most likely to add weeks regardless of how organised you are. A lease with an unusually short remaining term, or a chain with four links instead of two, both introduce delay points that no amount of preparation fully eliminates.

What happens on completion day, and what should you do first?

Completion day itself is mostly invisible admin between solicitors, but the sequence matters if you want a smooth handover.

On the day:

1. Your solicitor transfers the purchase funds to the seller's solicitor 2. Once funds clear, the seller's solicitor confirms completion 3. The estate agent releases the keys to you 4. You confirm your buildings insurance is active and utilities are set up in your name

In the first 24 to 72 hours:

• Take meter readings (gas, electricity, water) the moment you get keys
• Set up post redirection from your old address
• Notify your bank, DVLA and any subscriptions of your change of address
• Check the boiler, stopcock location and fuse box before you need them urgently

Post-completion, your conveyancer handles:

1. Filing your Stamp Duty return and payment with HMRC 2. Registering your ownership with the Land Registry 3. Sending you their final invoice, itemising any remaining disbursements

A note from our conveyancing team

Buyers ask us most often about timing, and the honest answer is that the legal work is rarely the slow part. Searches, chains and underwriting decide your timeline far more than your conveyancer's speed does. What we'd tell every first-time buyer is this: the single most useful thing you can do the day your offer is accepted is instruct your conveyancer immediately, before your mortgage offer even arrives. That one decision saves more time than almost anything else you'll do in the whole process.

Frequently asked questions

How long does the process of buying a house take from start to finish? Around five months on average, though chain-free or cash purchases can complete in as little as eight to ten weeks, while chains or leasehold sales often take longer.

What's the first step in the house buying process? Getting a mortgage in principle, so you know your realistic budget before you start viewing properties seriously.

Is a mortgage valuation the same as a survey? No. A valuation confirms the property's worth for the lender's security only. A survey checks its actual condition, and you should always commission one separately.

When should I instruct a conveyancer? The day your offer is accepted, not after your mortgage offer arrives. Early instruction removes a common source of delay.

Can a seller accept another offer after mine has been accepted? Yes, until contracts exchange, neither side is legally bound. This is known as gazumping, and moving quickly is the best protection against it.

What are the biggest costs beyond the deposit? Conveyancing fees, survey costs, search fees and Stamp Duty Land Tax, which together commonly add £2,500 to £5,000 on a typical first-time purchase.
