Why are you more affordable than a traditional architect?Our affordability comes from efficiency, not compromise. We operate a lean, digital-first model with low overheads. More importantly, our service is highly specialized. We focus exclusively on what's required for planning permission (RIBA Stages 0-3), avoiding the higher costs associated with the full-scope services (like detailed design, tender, and contract administration) that traditional firms provide. You pay only for the expert service you need to get your approval.
-
What's the difference between Planning Permission and Building Regulations?This is a crucial distinction. Planning Permission deals with the principle of development – the appearance of the building, its size, and its impact on the local area. Building Regulations are about the technical construction of the building, ensuring it is safe, structurally sound, and energy-efficient. Our service is focused on securing Planning Permission. Once that is granted, you will need a separate set of technical drawings for Building Regulations approval before construction can begin.
-
What if my application is rejected?We will refund your payment in full. While we have a very high success rate due to our thorough initial checks, planning can sometimes be unpredictable. If an application is refused, we will first review the decision notice to understand the council's reasons. Often, minor amendments are all that's needed. We will discuss the options with you, which could include submitting a revised application. Our goal is to be your partner through this process.
-
Do I need this service if my project is 'Permitted Development'?Even if your project falls under Permitted Development (PD) rights, it is highly recommended to obtain a Lawful Development Certificate (LDC) from the council. This is official proof that your build was legal at the time of construction. It protects you from future changes in planning law and is essential for when you come to sell your property. Our Permitted Development Package is designed specifically for this, providing the necessary drawings and managing the LDC application for you.
-
How long does the entire planning process usually take?To give you a clear timeline, the project kicks off as soon as you appoint us and the initial payment is made. The next step is the measured survey. After the survey is done, you can expect to see the finalized planning drawings in about 3-4 weeks. Once you're happy and give us your approval, we'll formally submit the application. The council's part of the process usually takes up to 8 weeks, but this varies between different councils.
-
What information do you need from me to get started?For the initial Free Feasibility Check, all we need is your property address and a brief description of what you'd like to achieve. Photos of the existing property are also very helpful. This allows us to conduct a preliminary review of local planning policies and your property's history. If you decide to proceed, we will then schedule a full site survey.
-
Are the council's planning application fees included in your packages?No, the council's submission fee is a separate, statutory cost that is paid directly to them via the Planning Portal when we submit the application. Our fixed fees cover our professional services for the survey, drawings, and application management. We will advise you of the exact council fee for your specific application type.
-
Will I have to deal with the council directly?No. As part of our service, we act as your official agent. This means we handle all correspondence and communication with the local planning authority on your behalf, from submission through to the decision. We take the stress and complexity out of the process for you and will keep you updated on any progress.
-
What happens after my planning application is approved?Congratulations! Once you have planning permission, the next step is to prepare for construction. This involves creating a more detailed set of technical drawings for Building Regulations approval and for your builder to work from. While our core service focuses on securing the planning approval, we can advise you on this next stage and recommend trusted structural engineers or building control surveyors.
-
Can you guarantee my application will be successful?No professional can ever guarantee a planning outcome, as the final decision rests with the local council. However, our expertise and thorough process are designed to maximise your chances of success. Our Free Feasibility Check is a crucial first step where we provide an honest assessment of the likelihood of approval. We will not advise you to proceed with an application that we believe has a low chance of success.
-
What if the planning process requires other professionals?Occasionally, for specific projects, the council may require a specialist report. For example, if there are significant trees on your property, they might request a formal tree assessment from an arborist, or a report from a heritage consultant for works on older buildings. While our service doesn't cover these third-party costs, we will guide you. We can recommend trusted professionals and will coordinate with them directly to provide all necessary project details, ensuring a smooth process where you don't need to get involved in the technical complexities. You would be responsible for appointing and paying them directly.
