Glasshouse planning application service

Choosing your perfect aluminium greenhouse is an exciting journey; from the design consultation through to deciding on those all-important features, we are here to make the process as smooth as possible. When it comes to starting your build, we understand that if your structure requires planning permission, it can appear daunting, which is why we offer a comprehensive planning application service.

Our in-house planning service is based on submitting an application on your behalf. We work with your local authority to complete and submit your planning application, and will keep you informed every step of the way as we monitor the progress of your application.

We have many years of experience in planning applications up and down the country, working with numerous local authorities.

Every application is different, therefore in sensitive areas or listed buildings, we recommend discussing your planning needs and requirements with your Sales Designer or Project Manager to advise on the best route. 


We have a success rate of over 95% on our applications – which means we take the stress out of your project so you can enjoy planning what you hope to grow in your greenhouse instead.

Do I need planning permission for a greenhouse?

We are increasingly finding Planning Permission is becoming an essential requirement for building a new greenhouse. Under permitted development rights, in some cases, planning permission will not be required; this will depend on the size and location of the proposed greenhouse. As the greenhouse is a significant and long term development we also think that gaining planning approval is prudent and good practice. Part of our service is to undertake all planning negotiations for you. Having completed countless applications over the years we can anticipate most eventualities. (Our success rate is over 95%!) You are however, free to submit your own planning application, particularly if you have a good ongoing relationship with your local planning office. We are well versed in understanding the needs of conservation officers and the nuances of the planning process. And we have nurtured strong links with the National Trust, English Heritage and the Royal Horticultural Society. As a general guide, planning permission will be required if any of the conditions listed below apply:
  1. The greenhouse is located on land at the front of the property
  2. The height of the greenhouse would exceed 4.0m for a dual pitch roof, 3.0m for any other roof. The height of the greenhouse would exceed 2.5m if located within 2.0m of a boundary
  3. The height of the eaves would exceed 2.5m
  4. More than 50% the area of land around the ‘original house’ would be covered by additions or other buildings
  5. In general if you live in a Conservation Area, Areas of Outstanding Natural Beauty, National Parks or the Broads, planning permission will be required. In these areas the maximum area to be covered by all outbuildings more than 20.0m from the house to be limited to 10msq. Greenhouses in these areas located at the side of the property will require planning permission
  6. Within the curtilage of a listed building, a greenhouse will require planning permission and, if built against a listed wall – listed building consent.
It should be noted that other consents may be required such as Party Wall agreements which we can advise and provide assistance with. When it comes to planning, Alitex can certainly advise on the best route forward. Our team of experts are continuously working with various planning authorities across the UK and will work with you or your chosen architect to try and satisfy the various criteria. Please contact us here to find out more about any potential planning permissions you may need for your greenhouse.

How long will the planning process take?

Our Sales & Project Support Team will submit and manage the application on your behalf, and we usually expect a decision from Councils in roughly 10 – 12 weeks after submission, during which time we will keep you updated with your progress.

Are Alitex Planning Consultants? 

No, our planning service is based on submitting an application on behalf of the householder. We offer this service purely based on our experience of making planning applications for a number for outbuildings across the country.

What happens if my planning permission is denied?

In the unlikely event your planning permission is denied, you will be entitled to your deposit back, minus administration costs. The administration costs themselves will vary, depending on how far along your project is, and the assistance we have provided you with.
