Sussex Property Market: Prices, Trends & Development Finance, Q3 2026 Review

Sussex spans two historic counties - East and West - combining the coastal cities of Brighton and Worthing with the rural South Downs and prosperous Wealden towns. Brighton is the South Coast's most dynamic property market, driven by London overspill, a creative economy, and strong student demand. West Sussex towns along the Arun Valley line offer commuter-belt family housing at lower entry points.

The Sussex property market recorded 22,498 residential transactions in the 12 months to 30 June 2026, with a median sale price of £362,488 — £77k above the approximate UK median of £285,000. Prices have been broadly stable, a year-on-year change of -0.3% across the county's principal towns.

On a quarterly view, Sussex median prices moved from £377,728 in Q1 2025 to £369,361 in Q2 2026, a change of -2.2% over 5 quarters.

Key drivers of the Sussex property market include Brighton's creative economy and London overspill, South Downs National Park lifestyle appeal, Gatwick Airport employment corridor. Additional factors include Coastal regeneration in Hastings and Bexhill.

Across 10 local planning authorities in Sussex, 193 residential planning applications were approved and 83 refused in Q3 2026 (1 July to 30 September 2026), with 470 still awaiting a decision. The decision-weighted approval rate is 70%. A further 5 residential decisions in the period have no recorded outcome in the source data and are not counted above. Planning figures come from local planning authority records compiled by Landstack, retrieved on 3 October 2026. Councils and Landstack can take several days to publish decisions, so decisions made in the final days of Q3 2026 may not all be included yet.

Schemes approved in Q3 2026, together with those still awaiting a decision, propose around 16,862 homes, an estimated £6.8bn of development value at local sale prices. Treat the unit total as an upper bound: an outline permission and the reserved-matters application for the same scheme are both counted.

Horsham was the busiest authority, with 7,590 proposed homes across 161 applications (42 approved, 20 refused, 99 pending). Where one authority covers several towns in this county, its figures are authority-wide, not a per-town split.

For developers, a high approval rate and a steady flow of consents signal where planning risk is lower and where lenders have recent comparable evidence to underwrite against. See the development finance options available for schemes already through planning in Sussex.

Understanding price variation across property types is essential for developers assessing scheme viability in Sussex. The spread between the most and least expensive property types indicates the range of development opportunities available.

Detached homes command the highest prices at £557,500, while flat properties offer the most accessible entry point at £210,000. This £348k spread suggests opportunities for developers converting or building across the type spectrum.

Sussex encompasses 10 principal towns, each with distinct market characteristics. The table below ranks every town by median sale price, alongside transaction volume and annual price movement.

Most expensive: Haywards Heath (£435,000), Horsham (£430,000), Chichester (£420,000). Haywards Heath's premium reflects its profile as mid-Sussex commuter town with fast Brighton and London services and strong family demand.

Most affordable: Hastings (£270,000), Eastbourne (£270,000), Bognor Regis (£330,000). These locations may offer stronger yields and lower entry costs for developers.

Most active: Brighton (4,170 sales), Bognor Regis (3,097 sales), Haywards Heath (2,653 sales). High transaction volumes indicate strong liquidity — critical for exit strategy confidence.

HM Land Registry has so far registered 416 new-build sales in Sussex for the past 12 months, 1.8% of registered transactions. New-build sales are typically registered 6 to 18 months after completion, so this understates current delivery and is not a completions figure.

In the 5 towns with at least 30 registered new-build sales, new builds sold at a transaction-weighted premium of 17.3% to existing stock.

The most registered new-build sales so far are in Bognor Regis (122), Haywards Heath (85), Chichester (70).

Sussex recorded 22,498 residential sales in the 12 months to 30 June 2026, representing an estimated £8.2bn in total transacted value. This is a deep, liquid market where developers can have confidence in their exit strategy.

Transaction activity is concentrated in Brighton (4,170 sales), Bognor Regis (3,097), and Haywards Heath (2,653), which together account for 44% of county-wide volume.

For developers, liquidity directly affects finance terms. Lenders are more comfortable providing higher loan-to-value ratios and competitive rates in areas with strong transaction volumes, as the evidence of comparable sales reduces valuation risk.

The Sussex market data carries direct implications for developers seeking finance. With a median property value of £362,488 and detached homes at £557,500, typical scheme GDVs support a range of finance structures.

For a standard development finance facility in Sussex, a scheme with a GDV of £557,500 would typically attract senior debt of £362,375 at 65% LTGDV. Mezzanine finance can stretch total borrowing to 85-90% of costs, reducing the equity requirement to as little as 10-15% of project costs.

For developers looking to acquire sites quickly — particularly at auction — bridging loans provide rapid access to capital, typically completing within 5-10 working days. Once construction is complete, development exit finance replaces the development facility at a lower rate, providing breathing room to sell units at optimal prices.

With prices falling by 0.3% year-on-year, experienced developers can still achieve strong returns by focusing on well-located sites with clear demand drivers. Lenders will scrutinise comparable evidence more carefully in a softer market.

For refurbishment and conversion projects, Sussex's existing stock — particularly flat properties priced from £210,000 — offers value-add opportunities where the uplift from renovation can generate attractive profit on cost.

Among the most recently registered sales in each Sussex town, these were the highest values. They illustrate the upper end of what is currently transacting, not the county's record prices:

These transactions highlight the achievable end values for premium developments in Sussex. Sales above £500k demonstrate appetite for higher-specification homes in desirable locations.

Sussex's property market is in a period of consolidation, with 4 of 10 principal towns recording year-on-year price growth.

The fastest-growing markets are Chichester (+3.4%), Brighton (+3%), Crawley (+1.4%). These areas offer the strongest market momentum for new development.

Conversely, Lewes (-2.3%) and Worthing (-2.9%) have seen price softening. For experienced developers, this can present buying opportunities — acquiring land at lower values while planning for a market recovery.

Looking ahead, Sussex's development pipeline will also be shaped by Coastal regeneration in Hastings and Bexhill, alongside the demand drivers set out above. Developers who align their schemes with these structural factors are best positioned to secure finance and achieve strong returns.
