Nearest match in each category, from a fixed list of Jersey 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 Jersey's roads and 40mph 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
Jersey has two residential broadband providers: JT — the island's own former state telecom, now Jersey's full-fibre network builder — and Sure, which completed absorbing Airtel-Vodafone's Channel Islands customer base in September 2025 (Airtel-Vodafone no longer trades as a separate operator here). Jersey's copper phone network is largely already history: JT finished building an island-wide fibre-to-the-home network back in July 2018 and has been retiring copper ever since — well ahead of Guernsey, where the equivalent copper switch-off was still under way through 2026. Always confirm actual coverage and switch-over status at this specific address directly with JT or Sure before assuming.
What would improving it be worth?
Modelled for this property in St Mary. Adjust build quality or size for this property
Value added is the extra floor area priced at £9,139/m² — the midpoint asking price per m² among 5 St Mary properties currently for sale that publish a floor area. Cost uses £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 Jersey actually approves that kind of application.
Unlike the value side of this table (priced from Jersey's own current asking prices), the £4k–6k new-build / £2k–4k refurbishment rates are carried across from guernseyproperties.gg, where they were supplied by that site's owner from local Guernsey experience — they have not been independently verified for Jersey, and construction costs plausibly differ between the islands. Treat the Cost and Net columns as an unverified placeholder until a Jersey-specific quantity surveyor's rate replaces them.

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 that state a floor area — a minority of Jersey's live stock, so treat the sample sizes shown as real limits, not decoration.
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 far more than it actually is — a bigger bed-count usually means 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 — the type-of-work approval rates show how often that kind of application actually succeeds.
This address may match La Grande Rue Wellhead (ref MY0080, Listed Building Grade 3) on the Government of Jersey's Historic Environment Record. Listed status is a real legal constraint: under the Planning and Building (Jersey) Law 2002, alterations, extensions and demolition of a listed building or place typically need Listed Building Consent, on top of ordinary planning permission.
Matched by address text against this site's own listed buildings register — a likely match by address, not a certified check. Confirm the exact listed status with the official gov.je record or the Government of Jersey's planning department before making an offer or planning any work.

Matched by house name/street and parish against the Places.je property transaction register — not a unique-ID lookup, so a shared house name could span more than one property. The "2024 prices" column carries each price forward at the island-wide repeat-sales index — it is what that sum of money would be at today's market level, not a valuation of this property, and it takes no account of the condition it was in then or any work done since.

Jersey planning permissions lapse after a set period if unbuilt; these applications fall inside the last 3 years and were not refused, so they are presumptively still capable of being implemented.

The work type shown is inferred automatically from the wording of the planning application's own description — it isn't stated by the applicant. The base cost range comes from published UK national renovation/build-cost guides for that type of project, and a ~25% uplift has been added to reflect higher shipping/import and skilled-labour costs in the Channel Islands — this is an estimate, not a published index. These figures are indicative only, not a quote: actual cost depends on specification, finish, ground conditions and the contractor. For anything serious, get a quote from a local quantity surveyor or builder.
