What bills do first-time buyers forget?

Renters often pay one bill that covers a lot. Owners pay for everything separately — and several of these costs don't exist at all when renting. Here's the full list with 2026 figures.

The monthly costs that catch people out

CostTypical monthly amount (2026)Why it's missed
Buildings insurance£15–25/moMandatory for a mortgage, but not something renters pay — easy to forget when budgeting from a rent figure.
Contents insurance£10–20/moOptional but recommended; often bundled with buildings insurance.
Life insurance / mortgage protection£15–40/moMany lenders strongly recommend this; not legally required but a real cost most buyers add on.
Ground rent / service charge (flats)£50–250/moCan be substantial for leasehold flats and is sometimes underestimated at purchase.
Boiler/home emergency cover£15–25/moNo landlord to call when the boiler breaks — many buyers add cover in year one.
Maintenance & repairs fund£50–150/mo (recommended)Rule of thumb is 1% of property value per year set aside for maintenance — on a £300k house that's £250/month.
Garden/outdoor costs£10–30/moEquipment, plants, occasional tree work — non-existent for flat renters.
Higher energy bills+£20–50/mo vs a flatHouses are larger and often less efficient than the flat someone may have rented previously.
Mortgage arrangement fee (one-off)£0–£1,500 (one-off)Some mortgage deals charge an upfront fee, which can sometimes be added to the loan (increasing monthly cost slightly) or paid upfront.
Add these up and a buyer moving from renting a flat to owning a 3-bed house can see £150–300/month in costs that simply didn't exist before — on top of the mortgage itself.

One-off costs at the point of purchase

CostTypical amount (2026)
Solicitor / conveyancing fees£800–£1,500
Survey (Homebuyer Report)£400–£900
Survey (full structural)£600–£1,500
Mortgage valuation fee£0–£300 (often free with the mortgage deal)
Stamp duty (first-time buyer, under £425,000)£0
Stamp duty (first-time buyer, £425,000–£625,000)5% on the portion above £425,000
Removal costs£300–£1,000
Land Registry fee£20–£135

For a first-time buyer purchasing at £295,000 (the Northampton average), stamp duty is £0 thanks to first-time buyer relief on properties under £425,000. The main one-off costs are solicitor fees, survey and removals — typically £1,500–£3,000 combined.

Why this matters for affordability

Mortgage approval is based on your income and the loan amount — it does not factor in any of the costs above. Two buyers approved for the same mortgage can end up in very different monthly positions depending on whether they've budgeted for buildings insurance, a maintenance fund, and the jump in energy costs from a bigger home.

Before exchanging contracts, build a full monthly budget that includes mortgage, council tax, buildings insurance, energy, water, broadband and a maintenance buffer — not just the mortgage repayment figure your lender quotes.
