Ask a first-time buyer what they need to buy a house, and most will name two figures: the deposit, and the mortgage it unlocks. Both matter enormously. Neither is the whole picture.
From the mortgage application and survey through to legal work, tax and moving day sits a run of smaller costs that can add thousands of pounds to the cash needed to buy — and, on more expensive or complicated purchases, considerably more. Because each one arrives separately rather than as a single bill, it’s remarkably easy to plan the deposit carefully and still find the account much emptier than expected by the time the keys arrive.
The costs below apply, broadly, across the UK — but the largest of them, property transaction tax, is set separately in England and Northern Ireland, Scotland, and Wales. The differences are significant enough to change a buyer’s budget by thousands of pounds depending on where they’re buying.
Property transaction tax: three different systems, not one
In England and Northern Ireland, Stamp Duty Land Tax (SDLT) is charged in bands: nothing on the first £125,000 of a standard purchase, 2% on the portion from £125,001 to £250,000, 5% from £250,001 to £925,000, 10% up to £1.5 million, and 12% above that under the current HMRC residential rates.
First-time buyers get a more generous nil-rate band, paying nothing up to £300,000 and 5% on the portion from £300,001 to £500,000. But the relief disappears entirely once the purchase price exceeds £500,000, at which point standard rates apply to the whole purchase. Where people buy jointly, the first-time buyer conditions have to be met by everyone claiming the relief.
Buying an additional property — typically a second home or buy-to-let rather than a replacement main residence — will usually bring the higher SDLT rates into play, currently five percentage points above the standard residential rates.
Scotland uses Land and Buildings Transaction Tax (LBTT) instead, administered by Revenue Scotland. The current residential LBTT bands are 0% up to £145,000, 2% on the portion up to £250,000, 5% up to £325,000, 10% up to £750,000 and 12% above that.
First-time buyer relief in Scotland works differently to England’s. Rather than creating a separate set of rates, it raises the nil-rate band from £145,000 to £175,000, reducing the bill by up to £600. Additional properties can also attract Scotland’s Additional Dwelling Supplement, currently 8% of the relevant purchase price in addition to the ordinary LBTT calculation.
Wales operates Land Transaction Tax (LTT) through the Welsh Revenue Authority. Under the current residential LTT rates, there is no tax on the portion up to £225,000, followed by 6% up to £400,000, 7.5% up to £750,000, 10% up to £1.5 million and 12% above that.
Wales offers no separate first-time buyer relief. Instead, the £225,000 nil-rate band applies to buyers generally under the main residential rates.
The practical effect is easier to see with the same property. On a £280,000 first home, an eligible first-time buyer in England or Northern Ireland currently pays £0 SDLT. In Scotland, the same £280,000 first purchase produces £3,000 of LBTT after first-time buyer relief. In Wales it produces £3,300 of LTT.
That is a £3,300 difference before the solicitor, surveyor or removal company has sent a bill.
A buyer moving between nations therefore shouldn’t assume their previous experience of the tax translates directly — and shouldn’t rely on a figure quoted by a friend whose purchase took place somewhere else or under an earlier set of thresholds. Property taxes change often enough that the official national calculator should be checked against the actual transaction before an offer becomes a financial plan.
Payment deadlines differ too. SDLT is normally due within 14 days of the effective date in England and Northern Ireland. LBTT and LTT returns and payment are generally due within 30 days in Scotland and Wales. In an ordinary purchase a solicitor or conveyancer will usually deal with the return and payment, but the money still has to be available when required.
Conveyancing: more than just the solicitor’s fee
Legal costs are one of the harder items to compare because firms don’t all present their quotes in the same way.
The solicitor or licensed conveyancer has their own professional fee, but there are also payments associated with searches, registration, money transfers and other parts of the transaction. These are often grouped under the broad heading of disbursements, although the amounts are not necessarily fixed across every property or jurisdiction.
Current MoneyHelper guidance on buying and moving costs suggests legal fees can be around £2,000 including VAT, with searches adding further cost depending on the transaction. Actual quotes can be lower or higher depending on property price, tenure, complexity and location.
Leasehold purchases tend to cost more because there is more legal material to examine: the lease itself, service charges, management information, insurance arrangements and potentially planned major works. There can also be administration charges associated with leasehold ownership and documentation, which is another reason a cheap headline conveyancing quote isn’t necessarily the cheapest final bill.
A buyer purchasing on a privately managed freehold estate can encounter additional title and management arrangements too, so “freehold” doesn’t automatically mean the legal work will be entirely straightforward.
If you’re selling one property while buying another, there are two conveyancing transactions rather than one. The useful comparison therefore isn’t a solicitor’s advertised starting price but the complete quotation for your actual transaction.
Check whether VAT, searches, registration fees, bank transfer charges, leasehold supplements and any other likely extras are already included or shown separately. Two firms can quote what look like very different prices while ultimately charging surprisingly similar totals.
Surveys: an optional cost that can save far more than it costs
In England, Wales and Northern Ireland, a buyer isn’t generally legally required to commission their own home survey. That doesn’t make a survey an unnecessary extra.
The appropriate level depends more on the property than on the buyer’s desire to save a few hundred pounds.
RICS Home Surveys are divided into three levels. Level 1 is a relatively basic assessment aimed at conventional properties in good condition. Level 2 goes further and is commonly suited to conventional homes in reasonable condition. Level 3 is the most detailed and is intended particularly for older, unusual, altered or run-down properties, or where major work is planned.
Prices vary with the property, location, complexity and level of inspection rather than sitting neatly at one national figure. A Level 1 inspection may start at a few hundred pounds; more detailed surveys cost more, and a Level 3 inspection on a larger or complicated property can exceed £1,000.
The useful economy is choosing the right survey, not automatically choosing the cheapest one.
There is another distinction first-time buyers sometimes miss: the lender’s mortgage valuation is not the buyer’s survey.
A mortgage lender may arrange a valuation to decide whether the property is acceptable security for the loan. That inspection is for the lender’s purposes and can be much more limited than a condition survey. A lender being prepared to mortgage the house does not mean an independent professional has told you the roof, drainage, damp, alterations or other parts of the property are satisfactory.
Scotland works differently again. Most homes marketed for sale come with a seller-provided Home Report, which includes a Single Survey and valuation, an Energy Report and a Property Questionnaire. A prospective buyer can still obtain further or specialist investigation where the Home Report raises concerns or where the property warrants it.
Where a survey identifies significant defects, the findings can also change the economics of the purchase. A buyer may seek further quotations, reconsider the offer or ask the seller to address something before proceeding. The seller doesn’t have to agree to a renegotiation, but knowing about a £15,000 problem before completion is a very different position from discovering it afterwards.
Mortgage-related costs
Mortgage costs are particularly easy to overlook because the interest rate attracts most of the attention.
Arrangement or product fees, booking fees, valuation charges and — where one is used — mortgage broker fees can all sit around the mortgage itself. Some products have no arrangement fee; others can charge £1,000, £2,000 or more. A lender may include its valuation at no charge, while another product may not.
The cheapest interest rate is therefore not automatically the cheapest mortgage.
Some mortgage fees can be added to the loan rather than paid in cash at the outset. That reduces the immediate amount needed to complete, but it does not make the fee disappear. It becomes part of the mortgage balance and, unless repaid early, attracts interest along with the rest of the borrowing.
That distinction matters when cash is tight. “I don’t have to pay this today” and “this doesn’t cost me anything” are not the same thing.
A broker or adviser can set out the actual costs attached to the products being considered, but for budgeting purposes the important point is to establish them early rather than discovering them after most of the available cash has already been allocated to the deposit.
There is also a less visible risk attached to several of these early costs. In England, Wales and Northern Ireland, a buyer can spend money on the mortgage application, searches, legal work and a survey before contracts are exchanged and the transaction becomes legally binding. If the purchase then collapses, some of that expenditure may simply be lost.
Scotland reaches legal commitment differently, through conclusion of missives, but the wider principle remains useful: some buying costs are incurred before you actually own anything.
That is another reason the amount required for a purchase should contain some margin rather than being calculated to the last pound.
The costs that arrive on moving day itself
Removals vary enormously with property size, distance, access and how much of the packing you do yourself. A modest local move can cost a few hundred pounds; a larger house or long-distance move can move comfortably beyond £1,000.
Buildings insurance needs a little more care than the often-repeated instruction to “start it on completion”.
For a conventional purchase in England and Wales, government guidance says buildings insurance should normally be organised for exchange because the buyer becomes legally committed to the property at that point. MoneyHelper gives similar exchange-stage guidance for England, Wales and Northern Ireland. Scotland uses conclusion of missives rather than an identical exchange-of-contracts process, so buyers should agree the correct start date with their solicitor and mortgage lender.
A leasehold flat can be different again because buildings insurance is often arranged for the whole building by the freeholder or management company and paid through the service charge. Buying a separate buildings policy without first checking the lease can therefore be unnecessary.
Smaller costs are individually less dramatic but collectively easy to underestimate: removals, mail redirection, changing locks, immediate repairs or specialist checks highlighted by the survey, and the things a move exposes only after boxes start arriving.
For someone moving from a furnished rental or a smaller home, necessary furniture and appliances can become one of the largest discretionary costs of the move. A washing machine, fridge, bed, curtains and basic furniture bought together do not feel like small purchases merely because none appears on the solicitor’s completion statement.
Leasehold and managed properties can create another category of expenditure. There may be service-charge apportionments, management or administration charges, estate charges or other sums arising from the ownership arrangements. These should be identified during conveyancing rather than discovered from the first demand after moving in.
What all of this adds up to
The attraction of a single national “average cost of buying” figure is that it seems to answer the question quickly. Its weakness is that tax alone can make the average irrelevant to the individual buyer.
MoneyHelper notes that buying or selling can involve more than £5,000 in fees before the deposit and property transaction tax are even included. The eventual figure depends on the property, mortgage, survey, legal work and move itself.
For a first-time buyer purchasing for £280,000 in England, for example, SDLT may be zero. Put the same buyer and purchase price in Wales and £3,300 of LTT appears immediately. Give another buyer a complex older property requiring a Level 3 survey, a fee-charging mortgage and more involved conveyancing, and apparently similar purchases can diverge again.
The better way to budget is therefore not to start with somebody else’s total. Price the components of your own transaction.
Just as importantly, understand when those amounts are likely to leave the account:
| Stage of the purchase | Costs that commonly arise |
|---|---|
| Mortgage and offer stage | Broker fee where applicable, mortgage booking/product or valuation fees if charged upfront |
| Once the purchase is progressing | Conveyancer’s initial payment, searches and survey |
| Before the transaction becomes legally committed | Enough cash must remain for the costs still to come; some money already spent may be at risk if the purchase collapses |
| Completion or settlement | Property transaction tax, balance of legal and registration costs, and any transaction-specific sums handled through the conveyancer |
| Moving and first weeks | Removals, appropriate insurance, immediate repairs, locks, furniture, appliances and the first ordinary household bills |
The exact sequence differs between jurisdictions and individual transactions, but the underlying cashflow problem is the same: the £2,000 needed three months from now is still part of the cost of buying even if nobody is asking for it today.
That is why a sensible purchasing budget is better thought of as three amounts rather than one: the money going into the property itself, the money required to complete the transaction around it, and the money deliberately left untouched for life immediately afterwards.
The money required to complete is not the same as the money it’s sensible to have left
This is where the calculation genuinely matters, beyond simply totting up numbers.
A buyer who has technically raised enough to cover the deposit, the tax, the legal fees and the survey — but who has emptied every savings account doing so — has completed the purchase and created a new problem in the same afternoon.
A boiler failure, leaking pipe, broken appliance or simply the ordinary cost of making an unfamiliar property liveable doesn’t wait politely for finances to recover.
Nor is every post-purchase expense an emergency. The first Council Tax or rates payment arrives. Heating and electricity bills become real rather than estimated. A flat may have service charges. A newer estate may carry an estate-management charge. Something the previous owner tolerated for years may turn out to be something you want to fix in the first fortnight.
There’s no universal figure that every buyer should hold back. Someone with secure income, low commitments and a recently completed new home is in a different position from someone stretching to buy an older property with several pieces of maintenance already visible. The appropriate emergency reserve depends on the buyer’s own finances and risk, and individual financial advice may be sensible where the margin is tight.
But treating “enough to complete” and “enough to complete comfortably” as two different numbers is one of the more useful distinctions a buyer can make.
The deposit gets you into the transaction. The rest of the budget is what gets you through it — and leaves you able to live in the home once it is finally yours.
