The Bank held rates. It did not promise relief.

London sale prices are falling while rents rise, prime transactions have slowed sharply, and the Bank of England’s inflation outlook has worsened. For buyers and sellers, the question is no longer simply whether to wait—but what waiting costs.

Market figures and commentary refer to this edition’s publication date. They are not a live valuation.

London’s price correction is not making every move cheaper

The facts: ONS figures published on 16 September show London house prices fell 3.3% annually in July, while UK prices rose 1.4%. London private rents increased 3.5% annually in August. These are different measures and reference periods; July sales data do not describe September negotiations. The latest estimates are provisional. ONS, 16 September 2026.

Mark’s view: A falling purchase price and a rising cost of waiting can exist together.

For a renting buyer, another six months means another six months of rent. For a seller, it means carrying costs and continued exposure to competing homes. Neither makes rushing sensible. Both make “let’s wait and see” a decision that deserves a spreadsheet.

Sellers should assess an offer against the likely net outcome of waiting—not just the original asking price. Buyers should compare total ownership costs with renting, rather than treating a headline discount as proof of affordability.

An unchanged Bank Rate is not an unchanged mortgage market

The facts: On 17 September, the Bank held Bank Rate at 3.75%, voting 6–3, with three members favouring 4%. Its energy-price-based projection now puts inflation slightly above 4% in early 2027—not a guaranteed outcome. August CPI inflation was 3.1%, up from 2.9%. Bank of England, 17 September 2026; ONS, 16 September 2026.

The US Federal Reserve raised its target range by a quarter-point to 3.75%–4% on 16 September. But borrowing costs do not move mechanically together: UK long-dated gilt yields fell after the Bank announced a pause in gilt sales on 17 September. Federal Reserve, 16 September 2026; Reuters, 17 September 2026.

Mark’s view: “The Fed raised, therefore your mortgage must rise” is too simplistic. So is “the Bank held, therefore nothing changed”.

Buyers should ask their broker what can actually be secured, at what total cost, and until when. An agreement in principle is not the same as a reserved product or formal mortgage offer. Sellers should establish those distinctions before accepting an offer. The financing deadline may matter more than another round of negotiation.

Housing policy: delivery is the test

The facts: Reporting on 16 September said Barratt Redrow had reduced its expected annual completions to 17,500–17,900, from a previous upper target of 18,200, citing planning delays. This is a developer’s delivery warning, not a new government policy. The Times, 16 September 2026.

Mark’s view: Planning reform only becomes useful supply when homes are completed. Sellers should not mistake a long-term housing shortage for immediate pricing power; buyers should not assume promised construction will transform their chosen neighbourhood’s options this autumn.

Prime Central London: fewer competitors, but fewer transactions too

The facts: LonRes figures reported on 17 September show prime London August transactions down 19% annually, with achieved prices down 7%. New instructions fell 22.1%, and available sales stock was 1.1% lower. These cover prime London collectively—not separate price falls for Chelsea, Belgravia or Notting Hill. PropertyWire reporting LonRes, 17 September 2026.

Mark’s view: Reduced supply is not automatically bullish if fewer buyers are committing.

In Chelsea, a flat’s lease, service charges and planned works belong in the value proposition from day one. In Belgravia, demonstrate what makes the property difficult to replace; the address alone is not a negotiating strategy. In Notting Hill, distinguish a genuinely scarce family house from an apartment competing with several alternatives.

For sellers, scarcity must be specific and evidenced. For buyers, weak aggregate activity creates room to negotiate—not proof that every owner must accept a discount.

South West London: use the right comparable

The facts: ONS updates published 16 September, covering July, show annual average-price falls of 5.5% in Wandsworth, 6.3% in Lambeth and 9.0% in Hammersmith & Fulham. In Lambeth, flats fell 7.0%, versus 4.3% for terraced houses. Local estimates are provisional and more volatile than national figures. Wandsworth, Lambeth, Hammersmith & Fulham — ONS, 16 September 2026.

Mark’s view: Those figures argue for sharper valuation—not a uniform percentage reduction across Putney, Clapham, Streatham and Fulham.

Compare the same property type, condition, tenure and position. Sellers should separate a pricing objection from an unresolved lease or refurbishment problem. Buyers should cost the work and financing before deciding a cheaper house represents better value. A borough average cannot price the roof, the lease or the layout.

Key takeaway

Waiting is a position. It is not automatically a strategy.

Sellers need a credible price and a buyer whose funding can survive the timetable. Buyers need an affordable purchase—not a prediction that rates or prices will rescue the numbers later.
