Extension Plans UK - Excellent, and Efficient
I recently used Extension Plans UK, and they truly took the stress out of the entire process of drawing up plans and securing council approval. Remarkably, my council approval came through in just two weeks! Rebecca and the team was incredibly efficient and responsive, always addressing my queries quickly—usually within a day, if not within a few hours. They also connected me with trusted professionals for party wall and drain inspections to help carry the project through to completion. I can't recommend them highly enough. Plus, their pricing was very competitive, making them an excellent investment. Worth every penny!

On time, easy and cost-effective
Extension Plans UK produced drawings and applied for planning permission on our behalf. The service was easy and speedy, for much less than employing local architects. We got planning permission and have been put in touch with professionals to take on all other aspects of the job - party wall solicitors, builders, drain surveyors etc.

We had a great experience working with…
We had a great experience working with Extension plans and with Joshua our architect. We are super happy with our design. Big shoutout to Rebecca too—she kept everything organised and was always quick to respond, which made the whole process way easier. Such a solid team!
Pre-construction project ( loft conversion)
I used extension plans for my pre-construction project ( loft conversion). I saw this company online and wasn’t sure at first as to whether or not to use them.
But as soon as I had the telephone consultation with Philip and stated my requirements, I was reassured that all these can be met at a fixed price.
Once I made up my mind to proceed and paid the required invoice, everything went smoothly and speedily.
Extension Plans work at your own pace. They are transparent, they explain every stage of the process and give you many opportunities to ask questions.
They are fast, professional, efficient, and they produce the required results.
I am super happy with the service I received from Extension Plans and would highly recommend them.
Thanks to Philip, Rebecca, Joshua (fantastic drawings by the way Josh!) and Thant for your professional, speedy, efficient and effective service.
Kind regards
Elizabeth Okrekson.
Fast, good quality, responsive
Phillip, Rebecca and team made a confusing process easy to follow through excellent communication. Their work was speedy and high quality throughout, I would definitely hire them for future builds.
Couldn’t recommend enough
Couldn’t recommend the company enough. Very competitive prices, clear and timely communication and very professional at every stage. Everyone we spoke to in particular Rebecca and Kate were excellent to deal with.
Great Customer Service
Firstly, your cost was very competitive and you allowed reasonable flexibility for payment. Secondly, your agent, Mackenzie Petcher, provided excellent customer services. She's courteous and polite and always available to assist when she's needed. She also provided valuable tips when I was seeking council approval for my house extension plan. She's an asset to this company.

Single storey rear extension
We used Extension Plans UK for our single storey rear extension plan. They team was really great at working with us to define what we need. They managed the project all the way up to building regs. They have a team that is always available. They explained every step of the way and even helped us amend the plans to the council with a small change we wanted to make for a reasonable, small fee. I would highly recommend them.

Renovation project
We have recently used Extension Plans and our experience with them have been excellent. The team are very professional, informative and have provided great communication throughout the process. From our initial consultation with Philip which was thorough, transparent and insightful. To our design drawings handled by Joshua who really took into considerations our wants/needs, we are extremely happy with the design he drew up for us.
Rebecca has been great handling the admin side of things keeping us well informed and updated with our applications.
We would definitely recommend Extension Plans UK as they have been transparent every step of the way and have provided us with excellent service throughout our renovation project.
Thanks Extension Plans UK team!

Reasonable quote price and prompt service
Got a reasonable quote price and they were prompt in coming over to get the measurement, prepare the plan and submit.
Got a reversed plan made and resubmitted when the first was rejected. And today I have my approval.

Great service and quick approval
Compared to other companies they were reasonable priced, but also offered a great service. They’ve kept us up to date at each stage and we’re happy to make amends to the plans as we progressed.

Excellent customer service
Everything from start to finish went smoothly. I was updated via email with progress regularly. This was very helpful. Mackenzie in particular went above and beyond to help in every way. Also Joshua and Cameron helped in getting the plans and calculations in order. I changed plans a number of times and each time all were very understanding and helpful. Would highly recommend Extension Plans.

Single Storey Rear Extension & Garage Conversion
We used Extension Plans UK for our single storey rear extension and garage conversion. Our experience was great - they were quick to perform the initial survey and deliver the plans, reacted promptly to several changes we needed to make subsequently to accomodate neighbours' wishes, and communicative throughout the whole process. We received planning permission approval successfully and a lot quicker than we expected. Highly recommended!

Great experience
Absolutely no hesitation in recommending Extension Plans UK. Phil in particular was great at taking our original idea and turning that in something we hadn't even considered making better use of the space. The plans were refined on subsequent calls and there were no issues with making some small changes. All plans were delivered on time. Mackenzie was also fantastic at keeping updated on progress. We're very happy with the final plans. Good value for money too.

Well worth using!
So happy with our plans for our Extension and garden office from Extension Plans UK. The whole planning process has been so painless and easy, even when our council were being very difficult and rejected our first plans. The guys at Extension Plans UK helped us rejig our ideas and actually ended up with a better layout than before which we’re much happier with. Cannot recommend them enough, they took out all the hassle with friendliness and professionalism. Also incredibly reasonable considering the end result!
