Your Deposit Is Not the Whole Bill: Seven First-Home Costs to Plan for in 2026

The deposit is the number that dominates first-time buyer planning. It is the figure on the mortgage illustration, the target in the savings account and the one relatives ask about. But in 2026, the deposit is only part of the bill. Between the moment an offer is accepted and the first month in the new home, a series of smaller costs arrive. Individually they look manageable; together they can add several thousand pounds. The risk is not just running short of cash. Moving money around at the wrong time, taking new credit or draining savings can complicate the mortgage application itself. This guide sets out seven costs to plan for and how to keep them from derailing your purchase.

1. Survey and valuation

When a lender approves a mortgage, it arranges a valuation. That is for the lender, not for you. It confirms the property is adequate security; it is not a home survey. A first-time buyer should commission an independent survey, usually a HomeBuyer report or a building survey if the property is older or unusual. The cost depends on the property value and level of detail. Do not skip it to save a few hundred pounds. A survey can reveal damp, roof problems or structural movement that changes your negotiating position or your budget. If you are buying a new-build, check whether a snagging inspection is included.

2. Legal work and searches

Conveyancing is the legal process of transferring ownership. It includes local authority searches, environmental checks, water and drainage searches, Land Registry fees and the solicitor's own fee. Leasehold purchases add more work: management packs, lease terms and service charge accounts. Ask for a fixed fee and a written estimate of disbursements, the third-party costs your solicitor pays on your behalf. Cheap conveyancing can become expensive if it is slow or misses a problem. A good solicitor will flag restrictive covenants, rights of way and planning issues before you are committed.

3. Lender and mortgage fees

Mortgage arrangement fees, booking fees, valuation fees and broker fees can add up. Some lenders allow the arrangement fee to be added to the loan, but that increases the balance and the interest you pay. A fee-free deal may have a higher rate; a low-rate deal may have a large fee. Compare the total cost over the fixed period, not just the headline rate. If you use a broker, ask whether they charge a fee and when it is payable. Keep evidence of how you paid any fees, because lenders ask about source of funds.

4. Tax and local charges

In England and Northern Ireland, Stamp Duty Land Tax applies above certain thresholds, with first-time buyer relief in some cases. Scotland has Land and Buildings Transaction Tax, and Wales has Land Transaction Tax. The rules, thresholds and reliefs differ, and they can change. Check the current position before you make an offer and budget conservatively. Do not rely on a headline figure from a website without confirming it for your purchase price, location and buyer status. Your solicitor should calculate the tax, but you need to know the cash requirement in advance.

5. Removals, storage and the gap

Removals costs are easy to underestimate. A professional van and crew, packing materials, insurance and a possible storage period can run into four figures. If there is a gap between leaving your old home and completing on the new one, storage and temporary accommodation may be needed. Budget for cleaning, mail redirection, connecting utilities and changing locks. If you are moving out of a rental, check the notice period and any early termination costs. A small overlap is often cheaper than a panic move.

6. Furniture, appliances and essential works

First homes often need more than a sofa. White goods, a bed, blinds, flooring, a boiler service, smoke alarms and basic tools are common early costs. Essential works such as rewiring, damp treatment or a new roof should be priced before exchange, not discovered after completion. Avoid applying for new credit or finance during the mortgage underwriting process. A new car loan or store card can affect affordability and cause a lender to review or decline the application. If family are helping with furniture, keep records of any gifted funds.

7. Ongoing ownership costs

Ownership does not stop at completion. Council tax, utilities, buildings insurance, contents insurance and maintenance all start immediately. Leasehold properties add service charges and ground rent; some also have estate management charges. Ask for the current budget and the last three years of accounts. A low service charge can hide a large future repair bill. Freehold homes still need a maintenance reserve for repairs. A useful rule is to keep a separate pot for the first year of ownership, so a boiler breakdown does not become a credit card problem.

Planning the full bill without derailing your application

Build a budget in three columns: deposit, purchase costs and post-completion costs. Add a contingency of at least five per cent of the purchase price for unexpected works and delays. Keep deposit funds in an account that can be evidenced, and avoid moving large sums between accounts without a paper trail. Lenders and solicitors must check source of funds and anti-money laundering rules. Do not take on new credit, change jobs or make unusual transactions while your application is being assessed. If you are receiving a gift, get a signed letter from the donor confirming it is a gift, not a loan. Speak to your broker before you commit to a completion date.

The £3,000 blind spot is rarely a single surprise. It is the survey, the searches, the removals, the blinds and the first service charge arriving together. Planning for the full bill is less exciting than choosing a kitchen, but it is what turns a mortgage approval into a sustainable move. General information only; not regulated financial advice.
