Rents in London cluster into three very different markets — central prestige, inner-zone fast-growth, and outer-zone catch-up. If your landlord proposes a 10% rise, whether that's defensible depends almost entirely on which of those three you're in.
Below is a borough-by-borough breakdown of median 2-bedroom rents in early 2026, year-on-year growth, and what it means for your renewal. Indicative figures aggregated from Rightmove / Zoopla listings and ONS Private Rental Market Statistics, rounded to the nearest £25.

Where rents are rising fastest
Five boroughs stand out for outsized rent growth in 2025–2026:
- Barking & Dagenham (+10.2%) — easternmost extension of the Elizabeth line effect; significant regeneration projects in Barking Riverside.
- Newham (+9.1%) — Stratford continues to anchor inflated growth across the borough; Plaistow and East Ham seeing spillover demand.
- Waltham Forest (+8.7%) — Walthamstow gentrification extending into Leyton and Chingford; strong cycling infrastructure pulling in young professionals.
- Lewisham (+8.3%) — Bakerloo extension speculation driving rents up in New Cross, Lewisham central and Catford.
- Croydon (+7.9%) — Westfield/Brick-by-Brick regeneration narrative finally landing; town-centre flats seeing biggest jumps.
If your tenancy is in one of these boroughs and your landlord proposes a 7–10% rise, run a careful comparable check before objecting — the local market may genuinely have moved.
Where rents are flattening
Central London — the historically priciest postcodes — has the slowest rent growth in 2026:
- Kensington & Chelsea: +2.4% YoY
- Westminster: +2.8% YoY
- City of London: +3.1% YoY
- Hammersmith & Fulham: +4.0% YoY
- Camden: +4.2% YoY
Two factors. First, these markets had already overshot in 2022–2024 and are now correcting toward a sustainable level. Second, the post-pandemic shift in work patterns has reduced central-London residential demand — tenants who'd historically pay a premium to be near the office now commute from Zone 3 once a week.
Practical consequence: if you rent in a central-London borough and your landlord proposes a 6–8% increase, that's above local market growth and probably challengeable at tribunal.
What it means for your renewal
The borough-level growth figure is the floor of what your landlord can reasonably argue for. Three rules of thumb:
- Proposed rise ≤ borough YoY growth: defensible. The local market has moved by at least that much. Negotiate at the margin, but a tribunal is likely to confirm the rise.
- Proposed rise = borough YoY + 0–3 percentage points: arguable. The landlord may be using a postcode-specific or property-specific argument. Worth challenging if your property is mid-range; worth pushing back on at minimum.
- Proposed rise more than 3 percentage points above borough growth: probably above market. A tribunal is likely to lower it. Apply.
Borough-level data is the starting point, not the answer. The tribunal wants postcode-level comparables. Run a check at RentCharter for your specific postcode and bedroom count — that's what matters at tribunal, not the borough average.
What it means for councils
If you're a London borough housing officer reading this: the data above is what your residents face. The boroughs with double-digit YoY rent growth are exactly the boroughs where Section 13 challenges would most help residents — and where renter-protection tools have the biggest impact.
Several London boroughs are already responding via selective licensing schemes (Newham being the original), PRS standards enforcement, and tenant-advice partnerships with Shelter and Citizens Advice. For councils wanting to add a free rent-fairness check for residents — without the casework load — see RentCharter for Councils.
Frequently asked questions
What is the average rent in London in 2026?
The all-London median for a 2-bedroom property sits around £2,100/mo in early 2026 — but the range across boroughs is huge. Inner-West London medians (Kensington & Chelsea, Westminster) push past £3,500, while outer-east boroughs (Bexley, Havering) sit closer to £1,500.
Which London borough has the cheapest rent?
Bexley, Havering, Sutton and Bromley consistently rank as the cheapest London boroughs by median rent in 2026 — typically 30–45% below the all-London average. They trade lower rents for longer commutes and less transport density.
Which London borough has the most expensive rent?
Kensington & Chelsea is the most expensive London borough by median rent, followed by Westminster, Camden and the City of London. The premium is partly central location, partly the prestige tail of properties skewing the median upward.
Where in London are rents rising fastest in 2026?
Outer East London (Newham, Barking & Dagenham, Waltham Forest) and parts of South London (Lewisham, Croydon) have shown the steepest year-on-year rises in 2025–2026 — typically 8–11%. These are areas with strong transport links coming online (Elizabeth line extensions, Bakerloo extension proposals) and historically lower rents catching up.
Is it fair for a London landlord to increase rent by 10%+ in 2026?
It depends on the borough and the starting rent. In Newham or Lewisham where the local market has grown 8–11% YoY, a 10% increase may be defensible at tribunal. In Kensington & Chelsea or central London where growth is flatter at 2–4%, a 10% increase is likely above market.
