London Property Market 2026: Prime Sellers Accept 10.1% Discounts as Luxury Homes Continue to Launch

New builds have shown us that although the sales market is slower, not all luxury homes are getting cheaper. This will depend on the location of the property, type of property, price they are asking for, the market and how long it takes to sell.

The latest figures reported by The National, drawing on property-market analysis from LonRes, indicate that prime London sellers are facing a more challenging sales environment than in previous years.

Three figures stand out:

• 10.1% average discount: The average reduction from asking prices accepted by sellers in prime London postcodes in September.

• 7.1% annual price decline: Achieved sale prices were lower than in September 2025.

• 16.8% fewer transactions: The number of sales was lower than in September 2025, with activity also 13.9% below the 2017–2019 September average.

The data also shows that September was the worst month on record for sales since 2016. This indicates that there has been an increase in buyers becoming more selective, and sellers may need to be more realistic with their expectations to get a sale through.

It’s important to note that the 10.1% discount is the difference between what the property was originally asking for versus what the seller accepted for it. Whereas the annual decline of 7.1% shows how much less was achieved compared with the previous year.

Several factors are contributing to the difficult conditions facing London’s high-end residential sector.

1. Borrowing Costs and Buyer Caution

Factors such as high borrowing costs and uncertainty around future price growth have been highlighted in the report from October 22. Global uncertainty and inflation have also contributed to a more cautious market.

If buyers are facing high costs to finance or are uncertain about the future outlook, they may decide to hold off purchasing, negotiate more aggressively or look for properties with higher perceived value.

This can cause longer times to sell and put pressure on sellers who need to sell their property.

2. Buyers Are Negotiating Below Asking Prices

The average discount demonstrates that the asking price and buyers’ willingness to pay are not always the same.

If a property was advertised for £2 million and the seller agreed to a 10% discount, then the property would sell for £1.8 million. This is just an example of how the percentage would work.

In reality, the outcome will depend on the individual property, competition from other properties, demand from buyers, availability of finance and sellers’ circumstances.

3. The Time Required to Sell Matters

The report also noted how the length of time spent on the market affected the amount of discount sellers received.

Properties sold within 3 months had an average discount of 3.8%. At the same time, properties that took between 6 and 12 months had an average discount of 11.1%.

This shows that having a realistic asking price can be very important in a slower market. Properties that take longer to sell may be put under pressure to lower their price.

These are just averages, so it doesn’t mean that you will be able to get that amount of discount.

Yes. New luxury properties continue to be put up for sale, despite a quiet market and lower prices.

The latest reports show that although there is less activity, there is still demand for luxury properties. Properties with lots of space, high-quality interiors and private outdoor spaces are still popular.

For example, a four-bedroom penthouse duplex at 100 George Street in Marylebone has been reported to be for sale for £15.5 million. This property is around 3,100 sqft and has a private roof terrace. A penthouse at Southbank Place has also been reported to be for sale for £20 million. Although these properties have high asking prices, it does not mean they have been sold or that the average price of properties in London is this high.

This is because there are a limited number of luxury properties available. Even if buyers in the wider market are becoming more cautious, there will still be demand for properties that are suitable.

According to Knight Frank’s Residence Report, larger new build apartments are currently limited in Westminster and Kensington & Chelsea.

Less than 3% of total completions in these areas are over 200m2.

This is why some developments are offering more. Large internal spaces, private terraces, bespoke finishing and move-in ready make some homes stand out from the crowd.

However, just because there is a lack of supply doesn’t mean they will be selling for a higher price or sell quickly. You still need someone willing and able to meet the seller’s expectations.

There is no one price for a London mansion. Prices will vary depending on location, size, style, condition, facilities and where in the luxury market it falls.

For example, in a recent report, it was reported that a mansion with views over Regent’s Park was sold for £11.5 million in early October 2026. This was purchased for £20.7 million around thirteen years ago.

This is an example of the price difference between a high-value property and how it can be sold for less than it was originally purchased for. However, this is an example of one property and does not give a benchmark for how much mansions cost. It also does not take into consideration inflation, running costs and renovations.

Furthermore, the penthouses that were sold for £15.5 million and £20 million are examples of asking prices.

When trying to value a mansion or any high-value property, you should look at recent sales of similar properties.

Prime London Property Listings Are Also Changing

Another market report was released by estate agents Benham & Reeves on October 22.

Their report showed that there were 3,778 properties listed on the market for £2 million or above within 14 prime areas of London at the end of September 2026. This was a decrease of 3.4% in available stock. 11 of the 14 areas saw a decrease in properties listed.

Findings are available in the Prime Central London Stock Index for Q3 2026.

The research shows that prime London is not a whole market.

Kensington had the most properties listed within the £2 million price point (698), followed by Chelsea (543) and Knightsbridge (357).

Fitzrovia saw the highest decrease in available stock within the quarter (16.5%).

The decrease in properties listed does not necessarily mean that demand is increasing. Properties may have been removed from the market due to selling, owners removing them, or sellers changing their mind. You should look at the number of properties listed in conjunction with how many transactions have taken place, what they have sold for and how long they have been on the market.

Overall, these two reports show that it is important to look at the supply and demand of the market when looking at price changes in London.

Could Tax Policy Affect London’s Luxury Housing Market?

Taxation and uncertainty around potential changes:

The UK Government have announced a High Value Council Tax Surcharge which will apply to residential properties in England that are valued at £2 million or more. This policy can be found on GOV.UK.

Uncertainty around speculation in the market relating to this was also discussed in the October 22 market report.

When considering high-value properties for purchase or sale, it is important to ensure you are aware of the tax implications, how they are valued, when they are applicable and your personal circumstances. The way this applies will depend on how the policy is structured.

You should not assume property prices will increase or decrease due to this speculation. Taxation can be a factor; however, there are many other factors to consider, such as the cost of financing, price expectations and availability of suitable properties.

The latest data shows that prime London property is very property-specific.

The discounts seen by buyers can mean that negotiation is an important factor. However, just because there is a big discount does not necessarily mean it is a good value property to purchase. You should compare completed sales, property condition, ongoing costs and your financial situation.

For sellers, pricing your property correctly is key. The discounts seen between the fast-selling properties and slow-selling properties mean that you may want to price your property realistically to avoid a long time on the market.

London luxury property provides a great example for international property investors. There are still risks involved even though it is a prestigious property. Exchange rates, finance, taxes, ownership costs and local regulations can all impact the economics.

The latest data is specific to prime London property and should not be used as a direct indicator for all of London, the whole of the UK housing market or other international real estate markets.

The London luxury residential market has been a mixed picture in the week ending October 22 2026. Sellers of prime properties have achieved an average discount rate of 10.1%. Achieved prices are lower year-on-year, and volumes remain low. However, new luxury properties are continuing to hit the market, and the number of prime properties available for sale has fallen in many parts of the Benham & Reeves research area.

The key takeaway is that the prime market is currently undergoing some changes. Buyers and sellers need to be mindful of discount rates versus achieved price changes and ensure they look at the local market to understand how specific properties might be performing.

1. Are London Property Prices Falling in 2026?

The latest report shows that prices in the prime London postcodes fell by 7.1% in September 2026 compared to the same time last year. This only refers to prime properties, however, and does not mean all areas of the London property market are suffering.

2. How Much Discount Can Buyers Get on Luxury London Property?

The average discount in prime London was 10.1% in September 2026. In reality, the discount will vary between properties, prices, market conditions and how long it takes to sell. It is an indication of the average discount historically in the market.

3. Does a Lower Asking Price Mean a London Property Is a Good Investment?

Not necessarily. Buyers should look at comparable property sales, property condition, financing, taxes, ongoing costs and your investment goals. Just because there has been a price reduction doesn’t mean that it’s undervalued or will increase in value.
