Nearest match in each category, from the island place register (OpenStreetMap plus local sources) — a broad list, not a guarantee that every business is included. 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.
A flat owner owns the inside of the flat — not the roof above it, the ground beside it, or the right to build on either. Adding a bedroom, converting the loft or putting up an outbuilding are not options here whatever they might be worth, so they are not costed. Internal work — reconfiguring, refitting a kitchen or bathroom, replacing windows where the lease and the building allow — is a different question, and one this site has no data to price.

Matched by house name/street and parish against the States of Guernsey property register — not a unique-ID lookup, so a shared house name could span more than one property. The "2026 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.

| FULL/2024/1285 | Install and alter balustrade to north-east elevation. Worked on by: CCD Architects | Granted Application details Official record Decision notice (PDF) |
Matched by house name/street and parish against Guernsey planning applications decided between 25 Aug 2021 and 26 Aug 2026 — coverage is partial and not a unique-ID lookup. No bare decision date is available in this data, so the application number (which embeds its year) is shown instead. Where a "Worked on by" name appears, it's a known architect or surveyor cross-referenced by the same application number — worth a call before commissioning a fresh survey.

Estimated cost of live planning permissions
Guernsey planning permissions lapse 3 years after grant if unbuilt; these applications fall inside that window and were not refused, so they are presumptively still capable of being implemented.
- FULL/2024/1285 — Internal alteration / change of use
£18,750–£50,000Install and alter balustrade to north-east elevation.
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.
