A high-rise residential building contains one or more high-rise residential structures. A high-rise residential structure has:

at least 7 floors or is at least 18 metres in height

at least 2 residential units

You may need to apply to register 2 or more structures as one building if they’re connected in certain ways.

Use the independent section criteria on each structure to help you decide if the structures are connected in one of those ways.

Types of buildings you do not need to register

Do not register buildings that are entirely used as a:

hospital

care home

secure residential institution

hotel

military premises

prison

Read the full guidance on buildings that need to be registered.

Check who can register the building

#

Source page 2

The principal accountable person (PAP) must make sure the building is registered.

A PAP is usually an organisation like a:

housing association

local authority

company

Someone from the organisation must be the single point of contact (SPOC) for BSR. The SPOC will:

discuss building safety issues with the regulator

have authority relating to the safety of the building

SPOCs cannot be the PAP or an accountable person (AP). The organisation is the PAP.

In limited circumstances, an individual can be the PAP. For example, if they are:

the owner of the building

named on the leasehold as responsible for maintenance of common parts

Authorising someone else to register

The PAP can authorise someone else to register the building for them. For example, they can authorise a managing agent or legal representative.

The authorisation must be in writing like an email, letter or written contract. Authorising someone to act for you does not make them the PAP.

A PAP is usually an organisation. You do not have to authorise individual employees of that organisation.

Register the building

#

Source page 3

New buildings must have a relevant completion certificate or final certificate. They must be registered before residents can occupy them.

You can apply to register a high-rise residential building online.

You will need:

the building’s name, address and postcode

a building summary, including height in metres, number of floors and residential units, and date of completion

the names and contact details of the PAP and APs

You’ll also need a credit or debit card to pay the £251 application fee for each building.

If you cannot pay by card, you may be able to pay by invoice. You must pay the invoice before BSR can assess your application. If you do not pay within 30 days of the invoice, BSR may reject your application.

Building summary

#

Source page 4

As part of the application to register a high-rise residential building you need to give BSR a summary of the building.

Number of floors at or above ground level

Count all floors from ground level to the top floor, whether they have residential units or not.

If all of a ceiling is at or above ground level, count the floor as above ground level.

Count mezzanine floors that are 50% or more of the area of other floors as separate floors. If a mezzanine floor is less than 50% of the area of any of the other floors, do not count it as a floor.

Do not count:

floors below ground level unless all the ceiling is above ground level

the roof

Ground level

Ground level is the level of the land immediately next to the building. If that land is uneven, it is the lowest part of the land immediately next to the building. All or part of a ceiling below that level is below ground level.

Top floor

The top floor is the top of the floor surface of the top storey of the building. Ignore the roof.

Height of the building

Measure the height in metres (up to 2 decimal places) from ground level to the top floor. Do not measure the roof.

You can estimate the height if the building:

has at least 7 floors

is clearly over 18 metres

Keep a record of how you estimated the height.

Number of residential units

Count all residential units, whether someone is living in them or not. A residential unit is a place where someone can live, like a flat, apartment, maisonette or a room in student accommodation.

When the building was completed

Tell BSR the year the building was originally built. If you do not know the exact year, you can select from a range.

For buildings completed in 2023 or later, you must tell BSR the:

name of the building control body that issued the completion certificate or final certificate

certificate number

certificate date

For buildings completed between 1985 and 30 September 2023, you should take reasonable steps to find this information.

For buildings completed before 1985, you do not need to give this information.

For buildings completed on or after 1 October 2023, you must also upload a copy of the relevant completion or final certificate. You will not need to upload a copy of the certificate if it was issued by the Building Safety Regulator.

Structure and fire safety information

#

Source page 5

You need to give BSR information about the building’s structure and fire safety, this is also known as key building information. BSR will ask you about:

fire and smoke controls

energy supplies, storage and generation

type of structure, roof, staircases and external walls

the building’s use

building work since original build

connections between structures or to other buildings

You should be able to get the information needed from the most recent fire risk assessment. If there’s an external wall system (EWS) appraisal, the information might also be there meaning you should not need to do a full separate survey.

You have 28 days after submitting your registration application to give BSR more detailed information about the structure and fire safety of the building. The information you give here will help you when you assess the building’s risks, as part of your safety case report.

Read the Building Safety Regulator: giving us information about structure and safety (key building information) guide to help you understand:

what structure and safety information BSR will ask for

how you might find it

Reviews

#

Source page 9

If you disagree with the decision about your registration, you can ask BSR to look at the decision again.

You must ask for this review within 21 days of the decision (excluding public holidays).

A review costs £302. You must pay this before BSR carry out the review.

If you cannot pay by credit or debit card, you may be able to pay by invoice. You must pay the invoice before BSR carries out the review.

When you ask for a review, you need to include the following information:

your name

an address in England and Wales that BSR can serve notices to (including notices in proceedings)

your email address

your telephone number

if you’re authorising someone else to act for you, their name and address

the name, address and postcode of the building the decision is about

a way to identify the decision being reviewed, like the application reference

your reasons for asking for the review

You should also tell BSR about any new information relevant to the original decision.

You must also confirm that you have told any other APs that you have asked for a review.

Contact BSR if you want to ask for a review. You cannot ask for a review over the telephone.

Making changes: after a building is registered

#

Source page 10

Once your building is registered, you must tell BSR within 14 days of becoming aware of changes to the:

building summary

PAP

APs

parts of the building each AP or the PAP is accountable for

You must tell BSR within 28 days of becoming aware of any changes to the building’s structure or fire safety information.

Changing a user

The person who completes the application is known as the primary user.

As the primary user you can:

access the register a high-rise building service to manage the building information

change the primary user

You will need your email address and application reference number to do this.

Adding a user

The primary user can add a second user to manage the building’s information.

You will need your email address and application reference number to do this.

The second user cannot add or change any users.

Taking a building off the register

You can ask BSR to take a building off the register if any of the following apply:

it now has less than 7 floors and are less than 18 metres in height

it now has less than 2 residential units

it was incorrectly registered

everyone has permanently moved out of the building, for example pending demolition

You do not need to tell BSR if your building is student accommodation that is empty over a holiday period.

If there are multiple APs for the building, BSR will send them a copy of its decision to remove the building.

Where an AP disagrees with this decision, they can ask BSR for a review.
