Leaseholder Alterations – Improving Your Home

If you are planning to carry out alterations or improvement works to your home, you will need to seek formal approval from the council, prior to any works going ahead. The following information provides guidance for obtaining the correct consents, types of work that can and cannot be carried out, plus related fees for obtaining consent for alterations.

Why do I need to do ask permission?

Obtaining approval is a condition of your lease agreement with the council.

To understand more about your lease and how this affects the work you wish to undertake, please see our webpage under New Tenancies and Leases.

What if I do not obtain permission?

If you undertake works without seeking the council’s permission, otherwise known as an unauthorised alteration, this is considered a breach of the terms of your lease. Unauthorised alterations are a serious matter and could have future implications for you as the leaseholder including:

  • Reinstating the property to its original condition if the alterations do not meet council standards. You will be required to meet any costs of reinstating the property to its original condition or making any further modifications to ensure compliance with building regulations. 
  • You are likely to encounter difficulties if you wish to sell your property. If you do not have landlord’s consent for alterations, this can delay the sale of the property as potential buyers will want to ensure that you received the consent for the works.
  • If you undertake works that could be considered as dangerous or do not meet standards for the granting of landlord’s consent, the council may also take further legal proceedings.

Obtaining Retrospective Consent

You can make an application for retrospective consent if you have already started or have completed works without obtaining permission. If you have partially completed work, you are advised to stop immediately as an application for retrospective consent does not guarantee your alteration will be accepted. There will be a non-refundable fee for retrospective applications and are issued at a higher cost than standard applications.

What Type of Work / What Permission is Required?

Minor works

Minor works such as painting and decoration, replacing fixtures and fittings, works of a “like for like” nature. 

Minor Works based on a “like for like” basis, for example Kitchen and Bathroom refurbishments – application where formal Landlords Consent is required. 

Minor Works - small scale works for example changes in the layout, moving/removing walls, creating a bathroom/shower room - a Licence to Alteration is required. 

Major Works

Larger schemes for example, basement development, loft conversion, roof terrace, extensions, conservatories – where a Licence to Alteration is required.  In addition, a Deed of Variation may apply.
