The real cost of buying in London: 2026 guide

By Elmar Distelhoff, Founder, Property Around London 12 min read Verified April 2026

23%

of London homeowners wish they'd budgeted more carefully for the cost of buying or renovating

29% of under-35s UK-wide

Most London buyers know the deposit number to the pound. Most can quote the asking price. Very few can tell me what the total cost of buying is going to be the day after completion — and that gap is the single most quantified buyer regret in the data we have.

This guide is the running total. Stamp Duty Land Tax (SDLT), conveyancing, surveys, mortgage fees, post-completion repairs, and the ongoing borough-specific costs you'll pay for as long as you live in the home. Every number is dated and sourced. The borough table further down ranks all 33 London boroughs by council tax — the largest controllable annual cost, which varies by nearly two and a half times across the city.

The honest goal is simple: by the end of this guide you should be able to write out, on one side of A4, what the next twelve months will actually cost you. If you can do that and the answer still works for you, you are in the 77% of London buyers who don't regret the budget side of buying.

Layer one

Stamp Duty Land Tax — the number you can calculate today

SDLT is the easiest cost to get right because the figure is published by HMRC and a calculator is one click away. It is also the figure people most commonly get wrong, because the bands changed on 1 April 2025 and a lot of people still quote the temporary higher thresholds that ended that day.

Standard residential rates (in force since 1 April 2025)

0% on the first £125,000 · 2% on £125,001–£250,000 · 5% on £250,001–£925,000 · 10% on £925,001–£1,500,000 · 12% on anything above £1,500,000. Unchanged for 2026.

First-time buyer relief: £0 SDLT on the first £300,000, then 5% on the portion from £300,001 to £500,000. Above £500,001, first-time buyer relief disappears entirely and standard rates apply. This cliff catches London buyers more than anywhere else, because £500,000 is a one-bed in Zone 2 — exactly the price point a London first-time buyer is most likely to stretch toward.

Additional property surcharge: If you are buying any second home, buy-to-let, or company-purchase property, you pay an extra 5% on every slice — not just the band above the threshold. The surcharge rose from 3% to 5% on 31 October 2024. Non-UK resident surcharge: A further 2% on top of all other rates.

Use the HMRC SDLT calculator at the asking price before you put in an offer, not after. Many buyers wait until completion to discover the number, by which point the budget is set.

Layer two

Conveyancing — what you're actually paying for

Conveyancing is the line on the completion-day statement that most buyers haven't budgeted properly for. In practice it covers your solicitor's bill plus the disbursements they incur on your behalf.

Compare My Move's 2026 London benchmark puts the typical buyer's conveyancing cost at £2,427 to £3,074, with leasehold transactions sitting at the higher end because they need more enquiries. London transactions are also pulled up by higher property values, more complex titles, and a higher proportion of newer-build buildings with managing agent involvement.

The fee covers your solicitor's time, Local Authority search, environmental search, drainage and water search, ID and anti-money-laundering checks, Land Registry registration, and the bank transfer to the seller's solicitor on completion. It typically does not cover the Stamp Duty Land Tax itself (you fund that separately), specialist enquiries on a leasehold flat (sometimes charged on top), or any indemnity insurance the seller asks you to take out for a missing planning consent.

Three honest questions to put to any conveyancer before instructing

Is the fee fixed or does it vary depending on what the searches return?
Are leasehold enquiries included or extra?
What's your last-three-month average completion timeline on a London flat?

A conveyancer who can answer all three concretely is a conveyancer worth working with. Add 10% to whatever fee they quote you for contingency on indemnity insurance, additional searches, and last-minute disbursements.

Layer three

The survey question

Two things matter here. The first is what kind of survey. The second is whose survey.

The lender's mortgage valuation is not a survey for the buyer. It exists to satisfy the lender that the property is worth what they are lending against. It tells you very little about the condition of the building you're about to spend hundreds of thousands of pounds on.

A buyer's survey is RICS-defined and comes in three levels:

The three RICS levels

Level 1 — basic Condition Report. Only suitable for new builds. Level 2 — HomeBuyer Report. Standard option for typical London flat or house in reasonable condition. £465–£685 typically (Compare My Move 2026, London skews higher). Level 3 — full Building Survey. Appropriate for older properties, structural concerns, Section 20 history, or anything you're planning to extend.

If you're buying a Victorian conversion or a pre-1960s terrace, the £200 difference between Level 2 and Level 3 is the cheapest insurance you'll buy all year. Don't economise here.

Layer four

Mortgage costs you didn't put on the spreadsheet

Mortgage interest is not in this guide — it depends on the rate market on the day you fix, and any number quoted today will be out of date within weeks. What you can plan for, with reasonable accuracy, is the menu of fees that arrive alongside the mortgage itself.

The fees menu

Product fee: typically £999–£1,999. Some products advertise "no fee" but trade against a higher rate.
Valuation fee: free, reduced, or a flat £200–£400 depending on the lender.
Broker fee: flat £400–£800 in London or commission-paid by the lender — ask which.
CHAPS transfer fee on completion: £25–£40 — small, but on the list.
Early Repayment Charges only apply if you remortgage during a fixed period.

A reasonable mortgage-fee budget for a typical London purchase is £1,500–£2,500 once everything is on the table.

Layer five

The first six months in the home

This is where the 23% regret rate gets caught short. The boiler that worked perfectly during the viewing fails in October. The seller's "fully working appliances" line turns out to be a fridge that is still working, technically. The Victorian sash windows need draught-proofing. The electrical report flags a rewire and the £4,000 quote arrives a week later.

The variance is genuine — the same flat can need £500 or £8,000 of work depending on what the survey turned up and how realistic the seller was. What I can tell you is that the buyers who don't regret this stage of the purchase have planned for it. The buyers who do regret it didn't.

A reasonable rule of thumb

Budget £3,000–£8,000 for the first six months of a London leasehold flat. Budget more if you've bought a freehold house, anything pre-1960, or anything where the survey flagged structural issues. Treat anything left over at month six as a windfall, not a budget surplus.

The 33-borough table: running costs after the keys are yours

Once you've moved in, the cost picture switches from one-off to recurring. The single biggest controllable cost is council tax, and it varies more than any other London running cost — by nearly two and a half times across the 33 boroughs.

*Estimated total adds £2,100 to council tax — a composite London-wide figure covering energy (Ofgem April–June 2026 cap for a typical 2-bed flat, ~£1,200–£1,400), water (Thames Water 2026–27 metered, ~£400–£500), and broadband (~£25–£30/month, ~£300–£360/year). Energy is uniform across London (single Ofgem region). Water is largely uniform under Thames Water (small parts of north-west London are Affinity Water). Broadband prices don't vary by borough, though fibre availability does. Always verify the specific figure for the property you're buying.

What this guide deliberately doesn't cover

Mortgage interest itself — depends on the rate market on the day you fix; talk to an independent broker. Affordability multiples — same. Deposit-saving strategies — separate guide. Lender attitudes to leasehold lengths, recent credit events, or self-employment — broker territory. Specific borough planning charges (CIL, Article 4) — outside scope for a buyer; relevant if you're planning extensions.

For the leasehold-specific cost layer — ground rent, service charges, Section 20 major works, lease extension premiums — see the London leasehold buying guide.

Frequently asked

Frequently asked questions

How much does it cost to buy a house in London beyond the deposit? +

On a £700,000 purchase as a non-first-time buyer, a typical 2026 London buyer pays approximately £25,000 SDLT plus £2,500–£3,100 conveyancing plus £500–£700 for a Level 2 RICS survey plus £1,500–£2,500 in mortgage fees plus £3,000–£8,000 for the first six months of running costs and repairs. That's roughly £32,000 to £39,000 on top of the deposit.

Do first-time buyers pay Stamp Duty in London? +

First-time buyers pay no SDLT on properties up to £300,000 and 5% on the portion from £300,001 to £500,000 (a maximum of £10,000). Above £500,001, first-time buyer relief disappears entirely and the standard SDLT rates apply.

Why is conveyancing more expensive in London? +

Compare My Move's 2026 London benchmark of £2,427–£3,074 reflects three structural drivers: a higher proportion of leasehold flats requiring more enquiries, higher property values that increase Land Registry fees, and more complex titles that demand more thorough searches.

Which London borough has the cheapest council tax? +

For the 2025–26 financial year, Wandsworth has the lowest Band D council tax at £997.75. Kingston upon Thames has the highest at £2,489.34 — a spread of £1,491.59, or nearly two and a half times.

What is a Level 2 RICS survey and do I need one? +

A Level 2 HomeBuyer Report is the standard buyer's survey for typical houses or flats in reasonable condition, with national costs of £465–£685 in 2026. Older properties, anything with visible structural concerns, or anything with a complicated repair history warrant the more thorough Level 3 Building Survey instead.

How much should I budget for the first six months in a new home? +

A reasonable London budget is £3,000–£8,000 for typical leasehold flats. Plan higher for freehold houses, anything pre-1960, or anything where the survey flagged structural or electrical concerns. Treat anything unspent at month six as a windfall.
