Where’s the method? Why Eastbourne property values need a formula

If you’ve ever bought or sold a house in London, you’ll know the conversation always comes back to one number: pounds per square foot (£/SqFt). It isn’t the only thing that matters, of course. A garden, a view, a south-facing kitchen, a quiet road, a good school catchment, the height of the ceilings, the state of the roof, all of these move the needle. But £/SqFt is the anchor. It’s the shared language. It’s the sense-check that stops a valuation from drifting too far from reality.

Down here in Eastbourne and the surrounding villages, that anchor seems to have gone missing.

The numbers don’t add up

Let me show you what I mean. Take three broadly similar properties currently sitting in the £1,250,000–£1,500,000 bracket in and around Eastbourne four-bedroom detached homes, comparable plots, similar condition, similar quiet residential settings.

Property A Meads— listed at £1,500,000, with an internal floor area of approximately 3820 sq ft. That works out at roughly £392.67 per sq ft.

Property B, Meads — listed at £1,400,000, with an internal floor area of approximately 1920 sq ft. That works out at roughly £729.17 per sq ft.

Property C Friston — listed at £1,375,000, with an internal floor area of approximately 3078 sq ft. That works out at roughly £446.72 per sq ft.

Three houses, broadly comparable, and the £/SqFt figure swings from £392.67 to £729.17. That’s a staggering 86% variation on what is essentially the same product. In London, an agent who valued three near-identical houses in the same postcode with that kind of spread would have some explaining to do. Down here, no one even seems to be checking.

This isn’t an attack on local colleagues. It’s an observation that the valuation process locally is largely vibes-based. Agents look at a couple of recent sales, take a view on what the seller will accept and the buyer will pay, and pluck a figure. There isn’t a formula being applied. There isn’t a benchmark being defended. As there is no shared method, the market struggles to reward the homes that genuinely deserve a premium and struggles to correct the ones that have been talked up.

The floor plan problem

Here’s the thing that frustrates me most: you can’t even do the maths if you wanted to, because the information often isn’t there.

At Noble Estates, we believe the floor plan is the single most important piece of information in any set of property details. More important than the headline photo. More important than the description. The floor plan tells a buyer how the house actually works, how the flow of the house works, room sizes, where the light falls, whether the kitchen and family space connect, and whether the principal bedroom has space for a wardrobe that isn’t from a doll’s house.

And, critically, a proper floor plan shows the total square footage.

Walk through the listings of local agents and you’ll find a real mix. Some don’t provide floor plans at all. Some provide a floor plan with room dimensions, but no overall square footage.  Some provide a sq ft figure that’s been measured to a different standard (not RICS) than the one next door. Without a consistent, total floor area on every listing, buyers are flying blind, and £/SqFt comparisons become impossible.

If we want a properly functioning local market, this has to change. Every set of details should carry a detailed, scaled floor plan with the total internal floor area clearly stated. (GIA)

Our quest: Bringing consistency to Eastbourne valuations

One of our missions at Noble Estates is to formalise valuations in the area to ensure greater consistency from one property to the next. That means measuring accurately, publishing the total sq ft on every listing, and applying a clear, defensible £/SqFt benchmark, adjusted, of course, for the factors that genuinely move value: plot size, condition, position, view, parking, outbuildings, school catchment, and so on.

Why does this matter? A few reasons.

Consistency builds trust. When buyers can compare apples to apples, they engage with the market more confidently and bid more decisively. Sellers, in turn, get cleaner offers from a deeper pool. Deals fall through less often because the price is based on something more solid than a hunch. RICS valuers use SqFt to help them value and recommend lending.

Consistency rewards quality. At the moment, a beautifully presented, well-extended home can end up valued not far above a tired equivalent next door, simply because the agent didn’t know how to defend the premium. A proper £/SqFt framework, with adjustments, lets the better house pull away from the average.

Consistency lays the foundation for growth. This is what local sellers should care about most. Markets with a clear, transparent valuation method tend to compound upwards. Each transaction informs the next. A new high becomes a new benchmark. Without a method, every sale is an island, and the market as a whole stops crediting the homes that have genuinely improved. Formalised values give the market something to grow from.

Consistency attracts outside money. London buyers in particular speak the language of £/SqFt fluently. When they look at Eastbourne and the villages and can’t get a straight answer on price per square foot, they hesitate. When they can, they buy.

I do have a vested interest in increasing property values

I should declare my interest. I live in Willingdon, so my campaign to see local values rise is partly self-serving!

Jokes aside, I genuinely believe Eastbourne and the surrounding villages are undervalued, particularly when you put us next to Brighton.

I can hear the pushback already: “It’s a different offering. Brighton is a city. You’re not comparing like with like.” Fair enough. But pause for a second on what we actually have here.

A quiet pace of life. Low crime, a stunning coastline, the magnificent South Downs National Park on our doorstep, excellent schools, both state and independent. A 30-minute hop to Gatwick. It takes around 90 minutes to get to central London by train. Property that, square foot for square foot, costs a fraction of what you’d pay in any comparable London commuter belt postcode and a meaningful discount to Brighton.

For a certain kind of buyer, that is an extraordinary offer. They just need the local market to present itself in a way they can read.
