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.
Price per square metre
£799,000 over 83 m² is £9,627 per m². Compared with other properties currently for sale that publish a floor area — the percentage is this property against that group's midpoint:
Floor area is parsed from the agent's own listing text (a stated size, or a figure mentioned in the description) — jersey's data carries no dedicated floor-area field, so coverage is partial. Comparisons are drawn from asking prices of properties currently for sale that publish a floor area, not achieved sale prices — the Places.je register records no floor areas at all, so a sold £/m² cannot be calculated from it. Sample sizes are shown in brackets; small groups move a lot. This is context for a conversation with an agent, not a valuation.
What would this cost to buy?
A live estimate, not a quote — change any figure below and everything recalculates immediately. Stamp duty / Land Transaction Tax uses Jersey's own standard-residence bands (see buying property in Jersey for the full table and how share-transfer property differs); the mortgage side is a standard capital-and-interest repayment calculation, not an offer from any lender.
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?
Every row assumes a house with its own roof and its own plot — a flat doesn't normally have exclusive control of either, so extensions, loft conversions and annexes aren't options in the way they are for a house, whatever the price-per-m² arithmetic might suggest. Treat this as not applicable to La Rue De L'etau, St. Helier.

Matched by house name/street and parish against Jersey planning applications decided in the last 3 years — coverage is partial and not a unique-ID lookup.
Estimated cost of live planning permissions
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.
