I want to improve my home.  Do I need planning permission?

Planning permission: What you need to know


If you're planning to do building work on your own home, you may be wondering whether you need planning permission. The answer is not always straightforward, as it depends on the nature and scope of the work you want to do, as well as the regulations in your local area. In this article, we explain what you need to know about planning permission for residential properties in the UK.


UK planning law regulates the development and use of land, including the construction, alteration, and use of buildings. The law is designed to balance the interests of property owners and developers with the public interest in protecting the environment and maintaining the character of neighbourhoods.


In England, the main legislation governing planning is the Town and Country Planning Act of 1990, and in Wales is the Planning (Wales) Act of 2015. These acts give local authorities the power to control development through the use of planning policies and decisions on planning applications.


If you want to do building work on your own home, you will typically need to submit a planning application to your local planning authority, which will assess the proposal against local planning policies and any relevant national guidelines.


For residential properties, planning permission is typically required for:


  • Building new houses
  • Changing the use of a building from residential to commercial use
  • Building a large extension or making significant alterations to the property that would alter its appearance
  • Building in an area designated as a conservation area
  • Building in an area designated as an Area of Outstanding Natural Beauty


However, in many cases, small projects such as building an extension or converting a loft may not require planning permission, as long as they fall within certain size and design guidelines, known as Permitted Development rights. These rights allow certain types of development to be carried out without the need to apply for planning permission. It's always best to check with your local planning authority to confirm whether planning permission is required for your specific project.


It's worth noting that even if planning permission is not required, building regulations approval may still be needed to ensure that the work meets certain safety and accessibility standards.


Permitted development rights are a set of guidelines established by the UK government that allow property owners to make certain types of changes to their homes without the need to apply for planning permission. These rights are intended to make it easier for homeowners to make small improvements to their properties, such as building an extension or converting a loft, without the need for a lengthy and potentially costly planning application process.


However, it's important to note that while permitted development rights can make it easier to make changes to your property, they are not without restrictions. The rights are subject to certain conditions and limitations, such as size, design, and location, and may be subject to change by the government.


Article 4 is a provision within the Town and Country Planning Act of 1990 (England) and Planning (Wales) Act of 2015 (Wales) that gives local authorities the power to remove certain permitted development rights in specific areas. An Article 4 direction is a notice issued by the local planning authority that removes certain permitted development rights in a specific area. This means that property owners in that area will need to apply for planning permission for certain types of work that would otherwise be allowed under permitted development rights.


It's important to note that the local authority has to consult with the community and the property owners before issuing an Article 4 direction, and they also have to give reasonable notice before it comes into effect.


If you are planning to do work on your property and you're unsure if an Article 4 direction applies to your area, it's best to check with your local planning authority for clarification.


In conclusion, understanding the planning permission process and the regulations that apply to your area is essential if you are planning to do building work on your own home. While small projects may be covered by permitted development rights, larger projects or those that involve significant changes to the appearance of the property may require planning permission. Additionally, building regulations approval may still be needed even if planning permission is not required. It's always best to check with your local planning authority for specific guidelines and requirements in your area, and to be aware of any Article 4 directions that may remove certain permitted development rights in your area. By doing your research and consulting the right authorities, you can ensure that your building work is completed to the highest standards and in compliance with all relevant regulations.

The Assumption Many homeowners feel confident they already have a “good builder.” Often this is someone recommended by friends, family, or colleagues. But what worked for someone else’s project may not suit your project. Builder selection is the single most critical step in any renovation or rebuild. Done carefully, it leads to a smooth build. Done poorly, it can cause budget overruns, stress, and disputes. Why Proper Vetting Matters Most builders are hardworking professionals, but homeowners often don’t carry out the right checks. Some unscrupulous operators may show finished projects or photos that were not their own work. Looking only at glossy, finished results is misleading - poor workmanship can be hidden behind plaster or paint. Without proper vetting, even well-meaning builders can be mismatched to the size, style, or complexity of your project. This is why vetting is not about being suspicious - it’s about protecting your investment and ensuring the builder you choose is the right fit. How to Vet a Builder Properly Look backwards: Review a project the builder completed at least five years ago. Speak to those property owners to see how the work has lasted over time. Look forwards: Visit a current live site. See how it’s managed day to day, how organised it is, and how safety is handled. Speak with current clients: Ask how easy and flexible the builder is to work with. Do they communicate clearly? Are they responsive to changes? Check references: Speak directly with at least two or three previous clients - don’t rely only on written testimonials. Verify insurances: Public liability, employer’s liability, and contract works cover are essential. Verify financial stability: Review the builder’s company structure and trading history. A builder under financial strain poses a risk to your project. Review documents: Are quotes and specifications detailed, or are they vague one-liners? Are they willing to work under a proper written contract? Confirm who does the work: Will the builder’s own team deliver it, or will it be subcontracted to unknown trades? Common Red Flags While most builders are professional, there are signs to be cautious of: Requests for a large deposit before work starts. Vague or one-page quotes with no detail. Reluctance to provide insurance certificates or references. “Too good to be true” pricing. Unwillingness to agree to a clear written contract. These are not criticisms of builders as a whole - they are practical safeguards to avoid risks. Case Study: From Risk to Confidence A homeowner in North London chose a builder based solely on a personal recommendation. The quote was vague, no insurance documents were requested, and the photos shown turned out not to be from the builder’s own projects. Within weeks, disputes arose over extras and workmanship. The BGP stepped in, carried out due diligence, and sourced an alternative builder who was properly insured, experienced, and well-matched to the project. “The BGP's process gave us clarity and confidence. The new builder was organised, insured, and easy to work with - the project turned around completely.” Why Professional Guidance Saves More Than It Costs At The Building Guidance Partnership, we don’t criticise builders - we partner with the right ones.

The Temptation Many homeowners are tempted to manage their own building project. The logic seems simple: cut out the cost of a project manager and save money. You already have a builder lined up, maybe one recommended by friends or family, and you feel confident that everything will go smoothly. But while it can work, managing your own build is a serious undertaking. Without preparation, it often leads to stress, delays, and costs spiralling out of control. What Project Management Really Involves Managing a build is not just about choosing finishes or chasing invoices. It requires: Coordinating multiple trades and suppliers. Handling schedules, deliveries, and staged payments. Ensuring compliance with building regulations. Managing risks, safety, and insurances. Keeping accurate specifications, contracts, and records. Even with a good builder, these tasks can overwhelm a homeowner. The Pitfalls to Watch For (Even with a “Good Builder”) Many people believe that because their builder is: “Tried and tested,” or Recommended by friends and family, … everything will go smoothly. Unfortunately, things can still go wrong. Hard to judge quality: Finished projects can look impressive, but hidden corners may have been cut. It is difficult for a homeowner to spot these issues. Knowledge untested: We rigorously test builders’ knowledge. Many homeowners do not - and miss key warning signs. Due diligence matters: We check business history, insurances, and financial standing. This step is often skipped, leaving clients exposed. Technical gaps: Homeowners often lack expertise in dealing with party wall agreements, public liability, and specialist insurances - all of which are critical to staying compliant and protected. The Benefits of Doing It Yourself To be fair, there are reasons why some homeowners still choose to self-manage: Potential savings on professional fees. Personal satisfaction from being hands-on. Full control over decision-making. Direct relationships with trades. For some, this works well - but only when they have time, knowledge, and systems in place. Case Study: From Chaos to Control A homeowner in Harrow decided to manage their own large extension. They trusted a builder recommended by family and assumed things would run smoothly. Within months, delays mounted, trades clashed, and costs increased as “extras” piled up. We were brought in to coach them through the rest of the project. With clear payment schedules, proper contracts, and regular reviews, they regained control. Why Professional Support Pays Off At The Building Guidance Partnership, we provide coaching for homeowners who want to take charge - and full project management when required. Either way, our involvement saves clients far more than our fees. 💡 With professional project management, clients often save multiples of the project management costs through: Better build quality – avoiding mistakes and rework. Preventing inflated builder extras. Reducing timing delays that push up costs. Correctly recovering VAT and council tax where applicable. Avoiding disputes by using clear, pre-agreed specifications and contracts. Take Control - With the Right Support Self-managing a build can be rewarding - but it is not for the faint-hearted. With the right coaching, you can avoid pitfalls, protect your budget, and finish your project with confidence. Book a free 20-minute consultation with The Building Guidance Partnership today. Let us help you decide if project managing your own build is the right choice - and give you the tools to succeed.

The Risk of Big Deposits You have found a builder, the price is agreed, and you are eager to get started. The builder then asks for a large deposit upfront. Many homeowners feel they have no choice but to pay, only to later discover delays, unfinished work, or requests for more money. Large upfront payments remove your leverage and place all the risk in your hands. If the builder walks away or progress slows, your money may already be gone. Disputes, stress, and spiralling costs often follow. Why Staged Payments Make Sense The professional approach is to use staged payments tied to progress on site. This is not about mistrusting your builder - it is about protecting both parties and ensuring the project runs smoothly. With staged payments: You keep control of cashflow. The builder has incentive to deliver each stage on time. Payments are transparent and predictable. Disputes about “extras” are reduced because each stage is defined. By contrast, a large deposit creates imbalance. You lose the ability to hold the builder accountable, and problems become harder to resolve. How to Structure Payments Properly 1. Agree milestones in advance · Foundations completed · Roof installed · First fix services complete · Plastering finished · Practical completion 2. Keep it in writing · Payment terms should be part of your written contract and specification. 3. Always hold a retention · Retain 5-10% until all snagging is completed. 4. Avoid cash · Pay by bank transfer so there is a record. 5. Challenge unreasonable demands · If a builder insists on many thousands of pounds upfront, this is a red flag. Case Study: Regaining Control A homeowner we supported in Wembley had agreed to pay almost 40% of the contract value upfront. The builder became slow to mobilise, then requested further money before completing the first stage. The client felt trapped and anxious. We stepped in, reviewed the contract, and helped renegotiate a staged payment plan tied to milestones. Work progressed more smoothly, and the homeowner avoided what could easily have become a financial disaster. “Once the staged payments were in place, we finally felt back in control. Sunil and his team gave us confidence that our money was safe and that the builder was accountable.” Why This Matters for You Payment schedules may sound like a small detail, but they are often the difference between a successful build and a costly dispute. A fair, balanced structure protects your investment, gives your builder clarity, and keeps the project moving forward. Take Action Today Do not let unclear payment terms put your project at risk.
