Commenting on this application

Registered No decision on our record yet.

The law’s 21 days ↗, counted from the site notice with public holidays left out, end on Thu 19 Nov 2026 (20 days left). From the council’s file: site notice posted Fri 30 Oct 2026. The council doesn’t publish a closing date, so this is worked out from its file. Comments that arrive later, before the decision, are often still considered, and the council’s file has the comment form.

Check the deadline and comment on the council’s website ↗

Comments are public: the council publishes them on the application’s file with the commenter’s name, and removes personal details such as addresses, phone numbers and email addresses. A comment should be about the proposal: the council can take only planning matters into account.

What the council can take into account

A planning decision must follow the council’s development plan unless “material planning considerations” point another way. Government guidance describes these as matters relevant to the planning decision. It says the courts have generally taken the view that planning is about the use of land in the public interest, so purely private interests, such as the effect on a neighbouring property’s value or the loss of a private right to light, could not be material considerations. Public views can be taken into account where they relate to planning matters; support or opposition is not in itself a reason to grant or refuse.

From GOV.UK’s Determining a planning application ↗ (checked 14 October 2026). The council’s page on commenting ↗ lists the matters it can and can’t take into account (read 14 October 2026).

Who decides planning applications from 31 October 2026

Where it stands

The plans and documents are on the council’s file. When it is decided, the decision notice there will set out any conditions or the reasons for a refusal.

Conservation and heritage on this street

Measured along the street’s line against the council’s boundaries. Whether a particular building is inside depends on where the boundary runs: each area’s page on the council’s site has its map. All 18 conservation areas

The council’s Article 4 direction on houses in multiple occupation covers the whole town (in force since 2 July 2012): turning a house into a shared house for three to six people needs planning permission. The council’s page ↗

Tree preservation orders within about 40 m of London Road’s line, from the council’s map data:

Indicative only — the council’s order is what counts. The council says of its tree order map data: “This dataset is under review and subject to change. Always refer to the Original Tree Preservation Order and associated plan for confirmation.” The council’s tree preservation orders page ↗

Flood zones, the coast and protected nature on this street

We place an application by the street in its address, so these say where London Road runs, not where the site’s boundary is. The application’s own documents on the council’s file show the site.

Flood zones

None of London Road’s line is in Flood Zone 2 or 3 on the Environment Agency’s flood map for planning. In the Agency’s words: “This means a site in flood zone 1 could still flood now or in the future.”

A street’s line is not an address. For a particular address, use the Environment Agency’s Check your long term flood risk ↗; for a planning site, its Flood map for planning ↗. Flood warnings in force now are on Live now.

The coast

The Environment Agency’s erosion map covers this frontage: one stretch of policy unit 4C24 Hastings (inc. the Harbour) ↗ in the Shoreline Management Plan, whose policy is Hold the line (Maintain/replace) in all three periods, 2005 to 2105: “Where protection is currently provided by coastal defence structures or managed beaches, and the intention is to retain a defence along approximately the current alignment. This will involve replacing defences when needed. Defence type, method and standard of protection may be modified over time.”

Part of London Road’s line is inside the map’s No Future Intervention zone to 2105, and none of it inside the zone to 2105 with the plan delivered.

The figures are the width of the map’s erosion zone, inland from today’s shoreline, on the Higher Central allowance. In the Agency’s words: “Two periods: Medium Term (up to 2055) and Long Term (up to 2105).” “Two management scenarios: With Shoreline Management Plans delivered and No Future Intervention.” “Three climate scenarios: Present Day climate (2020), Higher Central allowance and Upper End allowance. The two allowances use sea level rise data from UKCP18 RCP8.5 70th and 95th percentiles respectively.” “All distances are cumulative over time and given in metres.”

The data and associated information are intended for guidance only - it cannot provide details for individual properties.

The data shows areas of land likely to be at erosion risk but does not show the precise future position of the shoreline.

Erosion may happen faster or slower than what we show, and risk may change over time.

Responses filed as consultee comments, named as the file names them, with the day each was published. What they say is in each document on the council’s file.

Is a comment public?

The council’s page on commenting says: “All comments will be made available to view online and will be treated in accordance with our privacy policy.

If you think work doesn’t match what was approved

The council’s planning enforcement team looks into building work or a use that may not have permission, or may not follow the approved plans or conditions. Its page explains how to report it and which cases it deals with first: planning enforcement on the council’s site ↗

Our planning record starts on 21 April 2026, from the council’s weekly lists of new and decided applications. We list the site, the proposal, the dates, the decision, the comment counts and a permission’s conditions. We never copy a commenter’s or an individual applicant’s details; an applicant is named only when it is an organisation we can match exactly to a council, a registered charity or a company on Companies House. Planning is decided by the council, not by us.
