Frequently asked
Is Dagenham in a conservation area?+
Conservation area boundaries are drawn street by street, so whether a specific address in Dagenham (postcode district RM9) falls inside one depends on the exact pin. Check a site free to see whether your pin is inside one. The name and source record are in the site report (£9.99). Some English councils do not publish their conservation area boundaries digitally, so ask the council where it matters.
How do I check flood risk for a property in RM9?+
Choose the address in Dagenham and check a site free to see whether a mapped river or sea flood extent reaches your pin. The free check does not show the zone number. The site report (£9.99) includes Flood Zone 2 and 3 from the Environment Agency Flood Map for Planning and other flood checks.
Are there listed buildings near Dagenham?+
London has listed buildings ranging from Grade II to Grade I, and they can sit right next to unlisted properties. The grade and distance from your pin are in the site report (£9.99), sourced from Historic England's National Heritage List for England.
Can I extend my home in Dagenham?+
It depends on the exact address. A conservation area, an Article 4 direction or a listed building can remove permitted development rights or add consent requirements, and flood risk affects what the council will accept. Check a site free to see what applies to your pin, then ask the local planning authority before you commit to drawings.
What is in the site report for RM9?+
The free check shows whether your pin is in a conservation area, which council decides, and whether a mapped river or sea flood extent reaches it. The site report (£9.99, one-off, VAT included) covers everything we can check within 500 m of your pin, for 30 days, with the source for each finding and a PDF you can send on. The report link never expires. No account or subscription is needed. We show what we found, what came back clear, and where a source couldn't be checked. Some councils do not publish every dataset, so ask the council where it matters. This is a screening tool, not an official local authority search.
