Hidden Costs of Buying a House in the UK
Most people buying a home for the first time focus almost entirely on the purchase price. That is understandable, but it means the costs that sit on top of the purchase price often come as a shock. On a typical UK property purchase, those additional costs can add up to £10,000 to £25,000 or more before you have paid a single bill as a homeowner. This guide covers everything you should budget for before you exchange.
The costs before you even get the keys
Stamp Duty Land Tax (SDLT)
For most buyers, stamp duty is the largest single cost on top of the purchase price. The amount depends on the purchase price and whether you are a first-time buyer. First-time buyers pay no stamp duty on properties up to £300,000, and a reduced rate between £300,000 and £500,000. Above £500,000, standard rates apply. On a £400,000 property, a first-time buyer pays £5,000. On the same property as a non-first-time buyer, the bill is £10,000. If you already own a property, a surcharge applies. Check the current rates on the HMRC website as these change, most recently in April 2025.
Solicitor or conveyancer fees
You will need a solicitor or licensed conveyancer to handle the legal side of the purchase. Fees vary significantly, typically between £1,000 and £2,500 for a straightforward freehold purchase. Leasehold properties cost more because of the additional legal work involved. Some firms quote a low headline fee and then add charges for disbursements, so always ask for a full breakdown including the items below.
Searches and disbursements
Your solicitor will carry out a set of searches on the property: a local authority search, a water and drainage search, an environmental search, and potentially others depending on the location. These are not optional and typically cost £250 to £500 in total. They are usually listed separately from the solicitor's fee.
Land Registry fees
Registering the title of the property in your name costs a fee set by HM Land Registry. The amount is based on the purchase price. On a £300,000 property, the fee is currently £150. On a £600,000 property, it is £305. Your solicitor will handle this, and it appears as a disbursement on your bill.
Survey
A mortgage lender's valuation does not tell you about the condition of the property. You need a separate survey for that. A RICS Level 2 HomeBuyer Survey costs £400 to £900. A Level 3 Building Survey for an older or more complex property costs £700 to £1,500 or more. Skipping the survey to save money is a false economy, particularly on older properties.
Mortgage arrangement fee
Many mortgage deals charge a product or arrangement fee, typically £999 to £2,000. You can usually add this to the loan rather than paying it upfront, but if you do that you will pay interest on it for the full mortgage term. It is usually better to pay it upfront where you can. Compare the total cost of mortgages including fees, not just the interest rate.
Mortgage broker fee
If you use an independent mortgage broker, they may charge a fee of between £300 and £500, or take a commission from the lender, or both. Whole-of-market brokers who charge a fee often save buyers more than their fee by finding better products. Ask upfront exactly how your broker is paid.
Buildings insurance
Your mortgage lender will require you to have buildings insurance in place from exchange of contracts, not just from completion. Buildings insurance typically costs £150 to £400 per year depending on the property and location. Get at least two or three quotes and make sure the sum insured reflects the rebuild cost of the property, not the market value.
Moving and immediate costs
Once you have the keys, there is another layer of costs that many buyers underestimate:
Removal company
£400 – £2,000
Depends on how far you are moving and how much you have. Get at least three quotes. Midweek and end-of-month dates are typically cheaper.
Immediate repairs and replacements
Highly variable
Even if your survey gave the property a clean bill of health, most buyers find small jobs in the first few months. Budget at least £500 to £2,000 for immediate snags.
Cleaning and decorating
£500 – £3,000+
If the property has not been freshly decorated, painting and cleaning before or just after moving in is common. Doing it yourself saves money but takes time.
New locks
£100 – £300
You do not know how many sets of keys exist for the property. Replacing the locks on the front and back doors when you move in is sensible.
Utility connection and setup fees
£50 – £200
Switching energy providers, broadband setup fees, and changes to council tax registration all carry small costs.
New appliances
Highly variable
If the vendor is taking the washing machine, fridge, or oven, you will need to buy replacements. Check what is and is not included in the sale before you exchange.
Ongoing costs that catch people out
Beyond the one-off costs at purchase, owning a home comes with recurring costs that renters do not pay and that first-time buyers often underestimate when working out what they can afford.
Ground rent and service charges apply if you are buying a leasehold property, which includes most flats. Service charges vary enormously, from a few hundred pounds a year on a small block to several thousand on a large development with a concierge, lifts, or significant communal areas. Always ask for three years of service charge accounts before you exchange, and check for any major works planned or in progress that could result in a large bill.
Maintenance and repairs are the main cost that catches homeowners off guard. As a rough rule of thumb, budget between 1% and 2% of the property value per year for ongoing maintenance. On a £300,000 property, that is £3,000 to £6,000 per year. It will not all be spent every year, but the costs tend to cluster. A boiler failure, a fence replacement, and a blocked drain in the same year can easily add up to several thousand pounds.
Boiler servicing, chimney sweeping, gutter clearing, and annual electrical and gas safety checks are all costs that responsible homeowners carry, even in years when nothing goes wrong.
Leasehold: the costs that surprise buyers most
If you are buying a flat or a leasehold house, there are additional costs and complications that freehold buyers do not face. Service charges and ground rent are the most widely discussed, but there are others.
A lease extension costs money. If the lease has fewer than around 80 years remaining, extending it before you buy is strongly advisable, because below 80 years the cost of extension rises significantly and your ability to get a mortgage on the property is increasingly restricted. Lease extension costs depend on the property value and the remaining lease term, but can easily run to £5,000 to £15,000 or more for a central London flat.
Building insurance for leasehold properties is usually arranged by the freeholder and paid for through the service charge. Check what the building is insured for and whether it is adequate. You will still need your own contents insurance.
Major works levies can be issued by the freeholder for significant repairs to the building — a new roof, cladding replacement, lift refurbishment, or similar. There is no cap on these. Some buyers have received bills for tens of thousands of pounds a few years after purchase. Ask for the minutes of the residents management company meetings and any correspondence about planned works before you exchange.
