TL;DR
In short
- Your cash budget is individual: start with your deposit contribution, then add applicable transaction tax and quoted purchase costs.
- Some costs can arise before completion, while the remaining deposit, tax and legal bill are normally funded for completion. A contract deposit is part of your mortgage deposit, not an extra charge.
- Surveys and broker advice are choices in many cases; product fees may be paid upfront or added to borrowing, where lender terms allow, and then attract interest.
Buying a home involves more than the mortgage. Your budget needs to cover your contribution to the price, any transaction tax, legal work and the services you choose or your lender requires. MoneyHelper’s buying-cost guide can help you list those items, but the total will depend on the property, mortgage, location and circumstances.

How should I budget for buying a home?
Separate the money needed to complete the purchase from costs that may be paid earlier or continue after you move. The timing is agreed during the transaction; the process in Scotland, including missives and the date of entry, differs from England, Wales and Northern Ireland.
| Cost | When it may be needed | What to check |
|---|---|---|
| Mortgage deposit | Part may be paid as the contract deposit; the balance is funded for completion | This is your contribution to the price, not a second transaction fee. Low-deposit lending is conditional on the lender, property and affordability. |
| Searches, surveys and some mortgage charges | Often during the application or conveyancing process | They can be payable before the purchase succeeds. Check payment and refund terms. |
| Remaining contribution, tax and legal bill | Usually around completion | Your conveyancer can confirm the completion statement and the relevant tax process. |
| Product or arrangement fee | Upfront or added to borrowing where lender terms permit | Added borrowing attracts interest; it does not make the fee disappear. |
| Moving and ongoing costs | Before, at and after moving | Keep a separate allowance for removals, set-up, repayments, maintenance, utilities, Council Tax or Northern Ireland domestic rates, and applicable service or estate charges. |
Buildings insurance is normally a lender requirement, but confirm when cover must begin and whether block or lease arrangements already provide it. Contents and protection policies are separate choices.
Deposit
The deposit is the part of the purchase price not covered by the mortgage. For example, a 10% deposit on a hypothetical £250,000 purchase is £25,000; it says nothing about the tax or fees that may also apply. Some mortgages may accept a smaller deposit if their criteria are met. A no-deposit product can exist for eligible borrowers, but it does not remove purchase costs; see, for example, Skipton’s eligibility information. Compare the mortgage and keep the contribution separate from other costs.
Surveys, valuations and mortgage charges
Buyer survey
A buyer survey is usually a choice, although a lender can ask for further reports. RICS surveys vary in scope and price; obtain a quote for the property and service you need. A Level 2 survey is a visual inspection of accessible areas: installations and appliances are not tested, and hidden defects or specialist questions may need further investigation. It is not a guarantee that every problem will be found. RICS explains the survey types and costs.
In Scotland, most marketed homes require the seller to provide a Home Report, which includes a single survey, valuation, property questionnaire and energy report. Exemptions and further buyer or lender investigations can still apply.
Lender valuation

A lender valuation helps the lender assess the property’s security and loan-to-value position. It may be automated, desktop-based or involve a visit, depending on the lender and property. It is not a buyer condition survey. A standard valuation may be free or separately charged under the lender’s tariff, so check the mortgage illustration and product information. A survey-with-valuation is a distinct service; do not assume it will be accepted by the lender or save money. Nationwide’s explanation of valuations and surveys illustrates the distinction.
Product and arrangement fees
A product or arrangement fee is a mortgage charge, not a broker commission. It may be zero or variable, and fee-paying and fee-free mortgages should be compared on their total cost for your loan and intended deal period. If lender terms let you add a fee to the mortgage, interest is charged on it while it remains outstanding. The lender or adviser dealing with you must provide an ESIS before an MCD mortgage application unless one has already been provided; it covers relevant mortgage charges, not every cost of buying a home. See the FCA MCOB rules.
Mortgage broker fees
Brokers may charge no customer fee, a flat or hourly fee, or a percentage; lender commission may also be involved. Before proceeding, ask for the amount, when it becomes payable and any refund terms in writing. Do not assume a broker fee can be added to the mortgage: that needs agreement and, if financed, will bear interest. MoneyHelper’s guidance on choosing a mortgage explains the arrangements to compare.
Property transaction tax: use the rules for the country

Transaction tax may be nil, but a return can still be required. These are separate regimes: SDLT in England and Northern Ireland, LTT in Wales and LBTT in Scotland. Budget the amount through your conveyancer around completion and use the official calculator or current guidance for the property’s country.
England and Northern Ireland: Stamp Duty Land Tax (SDLT)
SDLT residential rates are charged by slices of the price. Ordinary bands are 0% to £125,000, 2% to £250,000, 5% to £925,000, 10% to £1.5 million and 12% above that. Eligible first-time buyers pay 0% to £300,000 and 5% on the portion to £500,000; no first-time-buyer relief applies above a £500,000 total price. All buyers must qualify and intend the property as a main home; prior relevant residential ownership worldwide can disqualify a buyer.
Additional-property rates generally add 5 percentage points, subject to ownership, value, joint-buyer and replacement-main-home rules. Buying before selling a previous main home may mean paying first and claiming a conditional refund after a sale within three years. Non-UK residence for SDLT purposes can add 2 percentage points; this is not determined by nationality. See HMRC’s additional-property guidance. SDLT payment and any return are generally due within 14 days of the effective date, usually completion; see HMRC’s payment guidance.
Wales: Land Transaction Tax (LTT)
LTT main rates are 0% to £225,000, 6% to £400,000, 7.5% to £750,000, 10% to £1.5 million and 12% above that, charged by slice. Wales has no separate first-time-buyer relief. Higher residential rates are a separate schedule, not an SDLT-style surcharge: ownership worldwide, value, joint-buyer and replacement-main-home rules matter. A conditional refund may be available when a previous main home is sold within three years. Use the Welsh Revenue Authority guidance; LTT is generally due within 30 days starting the day after the effective date.
Scotland: Land and Buildings Transaction Tax (LBTT)
LBTT residential rates are 0% to £145,000, 2% to £250,000, 5% to £325,000, 10% to £750,000 and 12% above that, charged by slice. Eligible first-time buyers have a £175,000 nil-rate band, saving at most £600; main-residence, worldwide prior-ownership, linked-transaction and no-ADS conditions apply.
The Additional Dwelling Supplement is generally 8% of the whole consideration in addition to LBTT, subject to conditions and transitional contracts. It is not triggered simply because a property will be rented out. Main-home replacement may avoid it, and conditional repayment rules can apply. An LBTT return is generally due within 30 days starting the day after the effective date, with payment submitted with the return.
Conveyancing and completion costs
For a mortgaged purchase, choose an appropriate legal professional who is acceptable to your lender. Ask for a case-specific quote that separates legal work, VAT where applicable, searches, registration, bank transfers and other third-party costs. Leasehold, title, property and transaction complexity can affect the bill. MoneyHelper’s guide to finding a solicitor or conveyancer sets out what to consider.
Your conveyancer will explain the completion statement and the payment process for SDLT, LTT or LBTT. Legal fees are not the last financial consideration: retain a separate budget for moving and the costs of owning the home after completion.
Summary
There is no single cash total for buying a flat or house in the UK. Build your own budget from the deposit contribution, applicable tax and written quotes for legal work and any services you choose or need. Check which payments are due early, which are due at completion, and which mortgage charges can be added to borrowing only under the lender’s terms.
FAQ
Frequently asked questions
What costs should I include when buying a house in the UK?
Include your mortgage deposit contribution, any SDLT, LTT or LBTT due, and quoted legal costs. Then consider searches, mortgage charges, any survey or broker service you choose, moving costs and an ongoing-home budget. The total depends on your purchase, mortgage and circumstances.
Is the contract deposit an extra cost on top of my mortgage deposit?
No. The contract deposit is normally part of your overall contribution to the purchase price, not a second deposit. Your conveyancer can confirm the amount and payment timing for your transaction.
Can I add mortgage fees to my loan?
Some product or arrangement fees may be added to borrowing if the lender permits it. Interest is then charged on the added amount, so compare the total cost and do not assume taxes, legal costs or every other fee can be financed.
Do I need both a lender valuation and a buyer survey?
A lender valuation is for the lender’s security assessment and may be automated, desktop-based or involve a visit. It is not a condition survey. A buyer survey is usually a separate choice, although a lender can require further reports; in Scotland, check the seller’s Home Report as well.
Which property transaction tax applies to my purchase?
SDLT applies in England and Northern Ireland, LTT in Wales and LBTT in Scotland. The amount can be nil, but eligibility, ownership history, property price and main-home or additional-property status matter. Use the official calculator or guidance for the country where the property is located.
