Nearest match in each category, from a fixed list of Guernsey amenities — not every pub, café or shop on the island, so treat this as a useful sample, not a complete picture. Distances are straight-line ("as the crow flies"), multiplied by 1.3 to approximate real road-network distance — this is an estimate, not turn-by-turn routing, and actual walking/driving routes may differ. Times assume constant average speeds appropriate to Guernsey's roads and 25/35mph limits: walking 4.5 km/h, cycling 14 km/h, driving 30 km/h — not open-road speeds, and they don't account for traffic, parking or terrain.
Getting connected
Guernsey's copper telephone network is being retired at the end of 2026, and every property on the island is expected to be connectable to the fibre network. In practice that means a purchase completing now will be a fibre connection, and a landline-only arrangement will not survive the switch-off — worth settling before moving day rather than after it.
Three providers sell residential broadband here: Sure, JT, Airtel-Vodafone. Airtel-Vodafone was acquired by Sure in November 2024, so the market is more concentrated than three names suggest.
This site has no per-address availability feed and so makes no claim about the speed or price at this property — check with a provider against the actual address before you rely on it. No provider pays this site anything, and these are ordinary links, not referrals.
What would improving it be worth?
Value added is the extra floor area priced at £6,271/m² — the midpoint asking price per m² among 120 Guernsey properties currently for sale that publish a floor area. Cost uses real Guernsey build rates: £4,000–£6,000/m² new build and £2,000–£4,000/m² refurbishment, depending on quality. Net is against the mid rate. The last column is how often Guernsey actually grants that kind of application.
| Improvement | Value it might add | Likely cost | Net | Granted |
|---|---|---|---|---|
| Add a bedroom (single-storey extension) A modest double plus circulation, built new. ~14 m² |
£87,790 | £70,000 14 m² · mid spec new build range £56,000–£84,000 |
+£17,790 | 97% (1,510) |
| Loft conversion with a bedroom Works inside an existing roof, so it prices as refurbishment rather than new build — which is why it usually wins. ~20 m² |
£125,414 | £60,000 20 m² · mid spec refurb range £40,000–£80,000 |
+£65,414 | 97% (148) |
| Two-storey extension Roughly 14 m² on each of two floors. ~28 m² |
£175,580 | £140,000 28 m² · mid spec new build range £112,000–£168,000 |
+£35,580 | 93% (86) |
| Garage, annexe or outbuilding Detached space is worth less per m² than main-house floor area. ~18 m² |
£67,724 | £90,000 18 m² · mid spec new build range £72,000–£108,000 |
−£22,276 | 90% (738) |
Two things it cannot see. First, it prices floor area at the local average rate — it doesn't know your plot, your roof, your outlook, or whether an extension is physically possible; nor whether your street has a ceiling price that no amount of extending beats. Second, the rate comes from asking prices of other properties currently for sale, because Guernsey's sold register records no floor areas at all — so it reflects what sellers ask, not what buyers paid.
The obvious alternative method is worse, which is why it isn't used here: comparing a typical 3-bed with a typical 4-bed suggests a bedroom is worth around £430,000 island-wide. It isn't — a 4-bed is generally a bigger house on a bigger plot, so that figure measures the mix of what's for sale, not the value of adding a room.
Before spending anything, get a builder's quote and talk to an architect — who is actually filing applications shows which firms are active and how often their applications succeed.
