Nearby

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.

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?

This table doesn't apply to flats and apartments

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 St. Helier.

See the island-wide improvement value calculator, built for houses.

Estimate the cost of work you're considering

No live planning permission is on file for this address, so there's nothing to price directly — pick the kind of work you're weighing up instead, using the same cost ranges this site applies to real Jersey planning applications.

Likely cost

How this is calculated

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.
