Alterations and improvements
As a Coastline customer, you're allowed to make some alterations and improvements to your home. This may be changing something that's already in place, such as flooring, or adding something new like a shed.
You may only make amendments to your home by asking for our permission first. Please use our simple online application form to make a request. Work must not start until written permission has been granted by Coastline.
We need to ensure the safety of your property, so we only allow you to make certain types of improvements. Please see our home safety section for advice on keeping safe.
Steps to take
- Check the list below to see the types of work we can give permission for, and any guidelines and conditions for the different types of work
- Complete the consent form to make your request. You can't go ahead with any work unless we give permission
- If your alterations are approved you will need to meet the conditions supplied with that approval
- If in doubt, contact us and ask for advice
- Please allow 10 working days for an initial response to your request. We will normally make a decision within 20 working days.
You can find out more by reading our Alterations and Improvements Policy below.
When do I need permission?
The short answer is, you always need to ask us for permission. The list below covers popular alterations or additions that you can carry out, as long as you have been granted approval from us and you meet the guidelines and conditions summarised below.
If these conditions aren’t met, we can ask you to reinstate the property back to how it was, at your cost.
For all permission requests you will need to contact us to make your request, and we will need to approve this before works begin.
We won't give permission if:
- you owe us money (you're in arrears)
- you don't have a valid Electrical Safety Certificate or Gas Safety check
- you're living in a new build home where there's still a defects period
If you're a leaseholder or shared owner
We would not normally grant permission for significant works such as extensions, structural works, conservatories and the installation of multifuel stoves unless your lease is for 100% ownership, meaning you can invest in your home.
Please contact us before making any changes.
We won't give permission for the following
This means you cannot carry out any of the work listed below to your Coastline home if you are a Coastline renting customer. This is typically because there is a risk to the structure or a health and safety risk to you and others.

We will consider granting permission for some alterations
You will still need to apply for permission before starting any work and important conditions must be met. A summary of the conditions for each type of work is set out below. When we grant permission, we will provide the detailed terms and conditions that apply, along with any approval documents.
Running a business from home
You must not use the premises for any business or trade purposes without our permission and planning permission. While we will judge every case on its individual circumstances, we would not allow certain businesses such as car repairs or taxi services. You should refer to your tenancy agreement and to the Customer Handbook for more information.
