Address amendment guide

Table of Contents

The Royal Borough of Windsor and Maidenhead act as the Street Naming and Numbering Authority under the Town Improvement Clauses Act 1847 section 64, and the Public Health Act 1925 sections 17-19.

Under these acts the local authority has the power to ensure that all streets and properties are correctly named and numbered.

It is council policy not to renumber properties that are numbered 13. Sequential numbering is used so that it is easier for the emergency services to locate a property.

Why address registration is important

Many organisations including the emergency services and Royal Mail use this address data to locate specific properties. The data is also used by other organisations for the provision of certain services, such as credit checking and insurance. Without the registration of a new or replacement addresses for properties this can lead to problems with the provision of these services. Therefore, the council will only process address amendments that are submitted via the online form.

Before completing the form please check that the property is located within our local authority area of The Royal Borough of Windsor and Maidenhead.

The following website will allow you to check whether the property is within our local authority area -

The allocation of a postal address or addresses does not prejudice, remove or abrogate the obligation to obtain building regulation approval , planning consent or consent under any other legislation in respect of the use, construction or alteration of the building or structure to which an address or addresses has been allocated. Failure to obtain such consents, where required, risks enforcement action being implemented. Further it is the responsibility of the owner and or the occupier to ensure compliance with the legislation relating to Business Rates or Council Tax where appropriate. RBWM is unable to guarantee the accuracy or frequency of address data in third-party organisations including Google.
