Valuation Guides
Leasehold flats are valued differently from freehold houses. Lease length, service charges, ground rent, building safety, and management quality all affect the price. This section explains how each one works and how to choose the right valuation route.
A freehold house is valued primarily on the property itself: location, size, condition, comparable sales. A leasehold flat is valued on the same factors plus a layer of leasehold-specific considerations that can move the price significantly: how long is left on the lease, what the service charge looks like, whether the building has a fire-safety issue, who manages the block and how well, and the structure of the lease itself.
This is why online valuation tools, designed around freehold houses, commonly overstate leasehold flat values by 5 to 15 per cent or more. It is also why valuing a flat properly takes more than a comparable-sales lookup. The same flat can be worth materially different amounts depending on the lease and the building.
This section covers the factors in detail, alongside a deep dive into marriage value (the key concept for short leases). It is written to help you understand how a buyer, a surveyor, and a lender will think about your flat, so you can plan a sale or a lease extension with realistic expectations.
Two detailed reads covering the technical side of leasehold valuation.
A factor-by-factor guide covering everything that affects a leasehold flat's value: lease length, defects in the lease, building safety, service charges, ground rent, management quality, location, and the flat's own characteristics. Includes typical discount ranges and the lender thresholds that can take a flat from mortgageable to cash-only.

What marriage value is, why it kicks in below 80 years, the formula behind it, worked examples, and what the Leasehold and Freehold Reform Act 2024 means for it. Critical reading if your lease is approaching or below the 80-year threshold and you are weighing up extension versus selling as-is.

One of the largest single value drivers. Above 90 years, minimal impact. Between 80 and 90 years, mild caution. Below 80, marriage value applies. Below 70, mainstream lenders pull out and the buyer pool is mostly cash.
High service charges or escalating ground rent reduce both buyer affordability and lender appetite. Many lenders restrict lending where service charge exceeds about 1 per cent of property value or ground rent exceeds about 0.1 per cent.
Unresolved cladding or fire-safety issues can reduce values by 20 to 40 per cent. Many lenders decline entirely without clear compliance evidence. The position improves once an EWS1 form is in place.
An absent freeholder, an unresponsive managing agent, or a poorly maintained communal area can knock 10 to 20 per cent off the achievable price. Buyers and lenders both treat management as a leading indicator of future cost and risk.
Size, layout, floor level, parking, and condition all matter as they would in any property valuation. Studios and small flats face additional lender restrictions where the floor area is below 30 square metres.
Section 20 notices for upcoming roof, lift, or external works often see buyers deduct £10,000 to £30,000 to cover the expected cost. Some buyers refuse to proceed until the work is completed.
Online valuation tools (Zoopla, Rightmove, mortgage-broker calculators) work by combining a flat's address and rough characteristics with comparable sales and applying a model. They are quick and free, which makes them a reasonable starting point for a rough order of magnitude.
For leasehold flats they are routinely 5 to 15 per cent too high, sometimes much more. The reason is that the underlying models are designed primarily around freehold houses. They do not see the lease length, the service charge, the ground rent, or the building safety status, and these are the factors that often move a leasehold flat's price the most.
Use an online estimate as a starting figure, not a final answer. For anything that depends on a real number (lease extension premium, sale planning, divorce settlement, probate valuation), get a proper valuation from one of the routes below.
Three ways to get a real valuation for your flat, each suited to a different need. Understanding what each one gives you (and what it does not) helps you pick the right one.
For a planned sale, getting one of each (a free agent appraisal, an optional RICS valuation if you need an independent view, and a free cash-buyer offer) gives you the clearest picture of what the flat is worth across different routes. Each one tells you something different.
By starting from comparable sales of similar flats and adjusting for the factors specific to your flat: lease length remaining, service charges and ground rent, building safety and any EWS1 status, the type and condition of the building, the management arrangements, location, and the flat's own characteristics (size, layout, floor level). Each of these can move the figure up or down by anything from a few thousand pounds to 20 per cent or more, which is why valuing a leasehold flat is more involved than valuing a freehold house.
Online valuation tools are useful as a starting point but commonly overstate leasehold flat values by 5 to 15 per cent, sometimes more. They are designed around freehold houses and do not pick up leasehold-specific factors such as lease length, service charges, ground rent, EWS1 status, or block-specific issues. Treat the figure as a rough guide, not a reliable answer.
Lease length is one of the largest single drivers, especially below 80 years where marriage value applies. After that, service charges and ground rent (because they affect what a buyer can afford), building safety and EWS1 status (which affects mortgageability), management quality (an absent or unresponsive freeholder can knock 10 to 20 per cent off), and the flat's own characteristics. Location, condition, and building type all play in too.
Each gives you something different. A RICS valuation is an independent professional opinion of market value, suitable for legal purposes (lease extension, probate, divorce). An estate agent appraisal is marketing-focused: what they think they could achieve on the open market. A direct cash buyer gives you a firm offer to actually buy. For a planned sale, getting two or three of these alongside each other gives you the clearest picture of what the flat is realistically worth across different routes.
It depends on the route. An online estimate takes minutes. A high-street estate agent appraisal usually takes 24 to 72 hours from arranging a visit. A formal RICS valuation typically takes one to two weeks from instruction. A direct cash buyer offer is usually made within 24 to 48 hours of you providing the basic information.
Not always exactly. A valuation is an estimate based on comparable sales and the valuer's judgement. The eventual sale price depends on actual buyer competition, the condition of the flat at the time of viewing, market conditions when you sell, and what the buyer's surveyor finds. Treat the valuation as the centre of a range rather than a single fixed number.
