How much money will I spend buying a flat or a house in the UK in 2026

Although a mortgage is usually used to finance the purchase of a home in the UK, you will still need a fair amount of cash to pick up the keys to your own property. The costs associated with arranging a mortgage, taxes, insurance, and the down-payment itself all add up to a sum that cannot be ignored when planning a move. So let’s find out what the current costs of buying a flat in the UK are.

As well as a mortgage, there are additional costs to buying a flat or house in the UK

How much money does it take to buy a house in the UK?

The cost of buying a flat or house in the UK depends on a number of factors, but in principle it is always in excess of £10,000. Although by far the largest part of this sum is the deposit, which should be atleast 5% or 10% of the property’s value, the other charges can be as high as £4,000 or £5,000. In the rest of this article we will go into the individual components of the cost of buying a flat in the UK.

What makes up the cost of buying a flat in the UK?

Deposit

According to data released by Barclays in December 2025, over 44% of first-time buyers opted for loans with an LTV of 85–90%, meaning a deposit of 10–15%, which, at current property prices, amounts to around £30,000–£35,000. This is a daunting amount for the vast majority of us, at least in a reasonable amount of time, but it is worth remembering that the vast majority of banks only require a 5% deposit, so if you are buying a house for an average of £285,000, you will need around £14,000-£15,000 in cash for your deposit, whereas if you are looking for a cheaper property, you will probably only need around £10,000. Alternatively, you might consider a loan with a 100% LTV, i.e. with no deposit required – such options are available in 2026, although they often require a different form of security.

Homebuyer survey

The homebuyer survey, or building condition report, informs the buyer of the technical condition of the property being purchased. Through a meticulous analysis of the condition of all installations and structural elements, possible defects and damage come to light. Sometimes it turns out that poorly insulated electrical wiring, rotten ceiling beams or developed mould outbreaks in the attic require such serious repairs that the purchase of the house at the originally agreed price is completely uneconomic. This is, of course, an excellent opportunity to renegotiate and, in some cases, a building condition report will save you from finding yourself in very serious financial trouble.

For the most part, appraisers catch the following defects:

• Moisture problems - damp patches on walls, mould outbreaks, high humidity in rooms, condensation on windows, bad smell;

• Roof leaks - can be the result of roof cracks, degradation of the insulation layer, rotting of load-bearing beams;

• Cracks in building walls - load-bearing walls crack when the ground under the building is unstable. Homes that were built in mining areas are particularly prone to this type of damage;

• Electrical and heating problems - older homes in the UK often have inefficient and sometimes even dangerous electrical installations that should definitely be replaced. Central heating radiators and furnaces may also require the intervention of a specialist to last for many years.

• Presence of asbestos - Asbestos is the bane of buildings erected in the second half of the 20th century. It is a very dangerous building material whose removal requires considerably expensive tools and cannot be carried out by amateurs;

There are different types of report and the main differences between them are based on the varying degree of detail, which of course affects the price of the report. Typically, such a service costs from £400 upwards, while you will pay no less than £600 for a more detailed inspection.

A homebuyer survey is recommended especially if the property you are buying is more than 50 years old or has been clearly neglected. The report is generally never required by banks, but commissioning one can be a very sensible move. Remember that it can sometimes identify issues early on that might otherwise lead the bank to refuse a loan.

Valuation fee

The Valuation fee is charged by some banks in connection with the visual inspection of the building for the purpose of assessing its market value. This is a necessary step because the value of the security for the mortgage, in this case the property, determines the maximum amount you can borrow and the LTV ratio, which is important from the point of view of the interest rate and therefore the amount of the instalment.

As such, the valuation fee does not affect the cost of buying a flat too much - although, according to Moneyhelper, such a service costs between £250 and as much as £1,500, the fee is often included in the cost of the mortgage, as is the commission. Just as importantly, the valuation can be combined with a condition assessment, which also reduces the cost.

Product fee

A mortgage fee, also known as a product fee, raises the cost of buying a flat by up to £2,000. Such a fee is charged to cover the cost of administration and processing the application. Many banks also offer commission-free mortgages, but for the most part, these are slightly less cost-effective. Some financial institutions also allow the commission to be paid in instalments - in that case, its monthly cost is almost negligible.

Information on all fees including valuation fees can be found in the so-called key facts document or ESIS (European Standardised Information Sheet), which the bank must provide to the mortgage applicant prior to the application.

In the context of mortgage commissions, we strongly recommend reading the article “Is it worth avoiding mortgage commissions?”

Mortgage broker fees

If you choose to use a mortgage broker to advise and support you through this whole administrative process, there may be a charge for this service, called a mortgage broker fee. Depending on your requirements, the extent of your relationship and the current market situation, the broker service can cost you either £300 or £800. Typically, however, it will be around £500-£600.

Stamp Duty Land Tax (England and Northern Ireland)

When buying a flat, be aware of stamp duty tax.

When buying a property, you must be prepared to pay tax. Stamp duty land tax (England and Northern Ireland), Land and Buildings Transaction Tax (Scotland) and Land Transaction Tax (Wales), is in fact almost the same tax, which differs only in name and amount. In principle, the obligation to pay it arises at the time of the transaction and the rate of tax depends on the value of the property.

Transaction tax rates vary depending on the purpose of the property - the cost of buying a flat for rent will be higher than for a house bought for personal use by a person with First Time Buyer status. First time buyers are exempt from paying tax on purchases up to £300,000 (March 2026). (Source: gov.uk).

Conveyancing (legal fees)

The cost of buying a flat in the UK ends with the legal fees for the whole process - conveyancing is a series of steps involved in changing the formal ownership of the property, filing the relevant tax return with HMRC, verifying the legal status of the plot and also reviewing the local development plan.

Conveyancing in theory does not have to be done by a solicitor or conveyancer - the law allows you to handle all the administration yourself. In practice, however, most banks only want to work with specialists and to enjoy the wide range of mortgages available, you basically have to pay a solicitor.

The conveyancing fee is derived from a great many factors - it depends on the amount of time spent, official fees, commuting costs, the ownership structure of the property and also its value and location - London is obviously the most expensive. If you benefit from government assistance schemes or the house is owned under a leasehold, legal services will be more expensive because it will take your conveyancer more time.

According to Moneysavingexpert, conveyancing fees range from £1000 to £2,500, but in our experience, you should expect a figure closer to £1,300 or £1,400 in 2026.

Summary

In total, the cost of buying an average-value flat is currently around £20,000, while the lion’s share of this, at around £15,000, is the deposit. Such a sum is certainly impressive, but keep in mind that raising it is entirely possible - most Extend Finance clients need less than two years to raise enough money from scratch to realise the dream of owning their own home.
