Frequently Asked Questions
How long does planning permission take in London?
Most applications are determined within 8 weeks. Some boroughs can be faster (6 weeks) while complex applications may take 13 weeks. We’ll give you a realistic timeline based on your specific borough and project type.
Do I need planning permission for my extension?
It depends on the size, location, and your property type. Many single-storey rear extensions fall under Permitted Development. However, conservation areas, flats, and Article 4 directions affect this. We offer a free assessment to determine what you need.
What’s included in your service?
Site survey, all planning drawings (floor plans, elevations, site location plan), planning application form, design & access statement where required, full submission to council, and ongoing liaison until determination. Council fees are additional.
What if planning permission is refused?
We have a 92% first-time approval rate. If refused, we offer free advice on amendments and resubmission. We can also handle planning appeals if appropriate. Our goal is to get your project approved.
Do you handle Building Regulations too?
Yes, we can provide Building Regulations drawings as an additional service. We work with approved structural engineers and can coordinate the full technical package needed for construction.
