UK Property Market 2025: Billionaire Exodus, Down-Valuations & Build-to-Rent Boom

The UK property market in November 2025 is experiencing dramatic shifts. Billionaires are quietly leaving. Surveyors are slashing valuations. Developers are stuck in the “jaws of death”. Yet one sector is racing ahead: Build-to-Rent. In the latest London Property Podcast episode, host Farnaz Fazaipour delivered a crystal-clear update on what is really moving the market right now. Here is everything you need to know and exactly where the opportunities lie.

High-Net-Worth Flight Accelerates

Lakshmi Mittal has become the latest billionaire to leave the UK, driven by sweeping tax changes that now capture worldwide assets after just four years and impose 40% inheritance tax on trusts. Over 12,500 high-net-worth individuals are expected to exit by 2027, taking £18 billion of annual spending power with them. The impact is immediate in Mayfair and Knightsbridge, where £10 million-plus sales have dropped 28% year-on-year. Trophy homes that once sold in days now sit for months and motivated sellers are accepting discounts of 12% to 18%. For cash-rich buyers, this is the deepest super-prime buying window in more than a decade.

Down-Valuations Reach Record Levels

One in four London purchases is now being down-valued by surveyors, often by 10% to 17% below the agreed price. Kensington, Chelsea and Belgravia are the hardest hit. A buyer who agreed £2.5 million suddenly finds the bank will only lend against a £2.1 million valuation and must find an extra £400,000 overnight or lose the deal. Almost one in five transactions collapse after valuation. The simple protection is to offer 8–12% below asking price from the start and never borrow to your absolute maximum.

Developers Face the “Jaws of Death”

Build costs continue to rise while sales prices remain flat or fall in many regions. Half of England is now considered unviable for new housing without major policy support. London completions are heading for just 15,000 new homes in 2025, the lowest figure since the Second World War. Less supply means rents will rise another 7–9% and existing stock in Zones 2–4 will keep appreciating.

Stamp Duty Freeze Before the Budget

Stamp duty receipts have surged to £12.3 billion this year after April’s surcharge changes. Buyers and sellers are now frozen, waiting for the Autumn Budget. Transaction volumes are down 22% year-on-year. Many expect another 1–2% surcharge on homes over £1.5 million. Completing before 31 March 2026 is looking increasingly attractive.

Build-to-Rent Defies the Downturn

While the sales market stalls, Build-to-Rent is booming. Investors have poured £2.6 billion into the sector in 2025, the highest figure ever recorded. New planning reforms in England and Scotland are accelerating delivery and institutional capital is flooding in. Gross yields range from 5.5% to 7.2% in Greater London and up to 8% in major regional cities. For anyone seeking stable, inflation-linked income without individual tenancies, forward-funded BTR schemes are the standout opportunity of 2025.

Your 2025 Action Plan

Cash buyers and debt-free investors should circle discounted super-prime stock and forward-fund BTR schemes today. Mortgaged buyers must offer 8–12% below asking, secure an independent pre-purchase valuation and choose flexible lenders. Sellers who price realistically and complete before the next Budget are still achieving strong results. Landlords switching portfolios to institutional BTR operators are locking in guaranteed rent forever.
