Understanding DA7 coverage
The August 2026 Ordnance Survey postcode snapshot contains 674 postcode units in DA7. Our directory records 674 postcode centres matched to our geographic or all-DA/RM coverage rules and 0 additional centres in the boundary-review band; 0 units have no usable coordinates. These are representative postcode locations, not a count of homes, customers or completed repairs. Low-precision locations and individual properties still need confirmation.
Why we need the complete address
DA7 is only the outward part of a postcode. Add the final three characters, house or flat number and the visit contact. A postcode centre represents multiple addresses, not an exact building boundary. New, unlocated and edge addresses need confirmation from the office; do not substitute a neighbour's postcode.
Choosing a repair in DA7
Select the appliance and brand below. A washing machine that will not drain, an oven that does not heat and a freezer temperature alarm need different information. Send the full model and exact symptoms without dismantling the appliance. We review the model, work, parts suitability and available appointments before explaining the next step.
Planning a built-in installation in DA7
Share the old and new models, cabinet dimensions, door arrangement and existing connection details. Mention any removal requirements or restrictions on entry, parking, stairs or lifts. Furniture changes, disposal, gas work and additional electrical or plumbing work must be separately agreed. The request form does not take payment or reserve an appointment.
Postcode information sources
Read the dataset method, date and attribution. Locality examples: Bexleyheath. These are examples of places with this postcode, not a complete town boundary.

Brand-specific repair guidance
Choose the exact brand and appliance. The office checks model suitability, parts and the work required. Brand listings do not mean that every model or fuel type can be repaired.
