What Does It Really Cost to Rent in London?
Answer first: Add rent, any separately payable bills, council tax and your actual commute to find the monthly cost. Then calculate signing cash separately: initial rent, the refundable deposit and moving costs. Compare a room, studio and whole flat separately, and do not count an already credited holding deposit twice.
Start with the right kind of rent
A room in a shared home is not a one-bedroom flat. Ask whether you get a separate tenancy or join a household's existing agreement, what facilities are shared and whether the landlord lives there. Our flatshare guide explains the tenancy/lodger distinction.
RentReboot's London rent hub, updated 1 October 2026, reports a £2,095 pcm one-bedroom whole-flat median from 45,310 listings first seen in a 90-day window. It excludes flatshare rooms. A separate 12–30 September room sample in our flatshare guide had a £950 pcm median across 12,074 room listings. Different dwelling types and windows mean these are context, not directly matched alternatives or an estimate for a particular street.
Both are asking rents, not completed tenancy prices. Whole-home statistics use one newest listing per address; missing flat numbers mean distinct flats can be grouped together. Read the methodology and local sample sizes before making a neighborhood comparison.
Build a monthly budget
| Cost | What to check |
|---|---|
| Rent | Pcm versus per week; whole home versus per person; any concession expiry |
| Council tax | Property band, borough bill, who is liable and applicable discounts |
| Energy and water | Included or separate; heating system; actual supplier estimate |
| Broadband and other bills | Contract term, setup costs and included services |
| Travel | Your route, office days, time of travel and eligible discounts |
| Other recurring costs | Parking, insurance you choose, and any agreed charges |
For an illustrative flat at £2,100 pcm, £160 utilities/broadband, £140 council tax, £180 travel and £70 other costs make £2,650 per month. Those bill figures are planning inputs, not current tariff quotes or a London average. Replace them with the address-specific costs.

Your rental budget
Start with an illustrative example. Replace every figure with your own quote; bills and fares shown are assumptions.
- Monthly housing and travel
- £2,650.00
- Cash still needed before moving
- £4,823.08
Upfront cash includes one month's rent, the deposit and moving costs, less the credited payment. A refundable deposit is excluded from monthly spending. This estimate does not check legal payment limits or application eligibility.
The calculator separates monthly spending from upfront cash. It does not decide whether a payment is lawful or whether an agent will approve your income. Keep your emergency savings and other living costs outside the housing subtotal when judging affordability.
Council tax and transport can change the comparison
Check the council's band and annual charge for the exact home. GOV.UK explains liability and discounts, including the 25% reduction where only one countable adult is resident. Student and shared-home situations require their own checks; ask the council if you are unsure. Divide the annual charge by twelve for a budget comparison even if the council collects it on another schedule.
Use TfL's fare tools with your route and attendance pattern. A Travelcard is not automatically the least expensive choice for someone travelling only a few days each week. Include the trip to the station, late shifts and journeys on services outside your assumed fare arrangement.
Budget signing cash without double-counting
For a covered private tenancy at £2,100 pcm and annual rent below £50,000, a five-week deposit would be £2,423.08, calculated as monthly rent × 12 ÷ 52 × 5. With £2,100 initial rent and £300 moving costs, the illustrative cash requirement is £4,823.08. A lower agreed deposit reduces it.
If a holding deposit is credited against rent or the tenancy deposit, subtract that credited amount from what remains due; do not add it again as another expense. Our deposit guide explains the different caps and protection requirements. Government payment guidance explains the initial advance-rent rule.
Budget FAQs
How much salary do I need to rent in London?
There is no single salary that makes every London home affordable. Compare your take-home income with all spending and savings needs, then ask separately about the landlord's screening criteria.
Are bills always included in a flatshare?
No. Ask which bills, any limits on use, and how increases or final balances are shared. Get the inclusions in the written agreement.
