Expert Planning Consultants Covering All London Boroughs

Navigating the planning system can be complex, time-consuming, and often frustrating. Whether you're looking to extend your home, convert a loft, create additional residential units, or undertake a larger development project, obtaining planning permission is often the most important step in the process.

At AY-PL, we specialise in preparing and managing planning applications throughout London and Greater London. For over 10 years, we have helped homeowners, developers, landlords, and investors secure planning permission for a wide range of projects, achieving a planning approval rate of over 90%.

Our role is simple: to guide you through the planning process, minimise risk, and maximise the chances of securing approval.

Planning Permission Specialists Across London

Every local authority has its own planning policies, design guidance, and approach to development. What may be acceptable in one borough may be refused in another.

Our team has extensive experience working across all London boroughs, including Brent, Camden, Westminster, Barnet, Ealing, Haringey, Harrow, Hillingdon, Richmond, Wandsworth, Lambeth, Southwark, Greenwich, Croydon, Bromley, Kingston, Enfield, Hackney, Islington, Tower Hamlets, Newham, Redbridge, Havering and many more.

Because we work across London on a daily basis, we understand the planning challenges that applicants commonly face and how best to address them before an application is submitted.

How We Help

Many planning applications fail not because development is impossible, but because the proposal has not been properly assessed against planning policy.

Before preparing any application, we take time to understand your property, your objectives, and the planning constraints that may affect the site. This allows us to develop a strategy that gives your project the strongest possible chance of success.

Our planning application service includes:

  • Initial planning and development advice

  • Site and feasibility assessments

  • Architectural design and planning drawings

  • Planning Statements and Design & Access Statements

  • Preparation and submission of planning applications

  • Liaison with planning officers throughout the process

  • Negotiation of amendments where required

  • Ongoing support until a decision is issued

From the first consultation through to the final decision notice, we manage the entire process on your behalf.

Types of Planning Applications We Prepare

We work on projects ranging from individual residential properties to larger development sites.

Common applications include:

House Extensions

Single-storey, double-storey and wraparound extensions remain some of the most popular ways of increasing living space and adding value to a property. We work closely with homeowners to create planning-compliant designs that respond to both the property and local planning policies.

Loft Conversions and Mansard Roof Extensions

Roof extensions can unlock significant additional space, particularly in London where development opportunities are often limited. We regularly prepare planning applications for loft conversions, dormers, hip-to-gable extensions and mansard roof extensions across London boroughs.

New Build Developments

Whether you are considering a single dwelling or a multi-unit residential scheme, we can assess development potential and guide your project through the planning process.

Conversions and Change of Use

We assist landlords and developers seeking to convert properties, create additional residential units, or change the use of buildings in accordance with planning policy.

Conservation Area and Heritage Applications

Development within conservation areas or involving heritage assets requires careful design and planning justification. We have extensive experience preparing applications in sensitive locations where planning scrutiny is often higher.

Understanding the Planning Process

Many clients are unfamiliar with how planning decisions are made.

Planning applications in England are primarily assessed under the Town and Country Planning Act 1990, the National Planning Policy Framework (NPPF), the London Plan, and local borough planning policies.

Although every project is different, the process typically follows a similar route.

We begin by assessing the site's planning constraints and development opportunities. Once a suitable design has been developed, we prepare the required drawings and supporting documents before submitting the application to the local authority.

The council then validates the application and begins a consultation period, allowing neighbours and statutory consultees to comment. A planning officer will review the proposal against local and national planning policies before issuing a decision or, in some cases, referring the application to Planning Committee.

Most householder applications are determined within approximately eight weeks, although larger or more complex developments can take longer.

Our team remains involved throughout the process, responding to planning officer feedback and helping resolve issues that may arise during determination.

How we work

  • Our free project appraisal provides an initial assessment of your development proposal, identifying planning opportunities, constraints, risks, and potential costs. Whether you're considering an extension, conversion, or new-build project, our expert team offers practical guidance to help you make informed decisions before committing time and resources.

  • Following our initial consultation, we will provide a detailed quotation outlining the scope of services, deliverables, and associated fees. Upon appointment, we will commence work on your project, prepare the required drawings and documentation, and guide you through each stage of the planning process until submission and determination.

  • Following appointment, we will arrange a site visit to undertake a detailed measured survey of the property. This includes recording existing dimensions, levels, and key site features. The survey information forms the basis of accurate existing and proposed drawings, ensuring the planning application is prepared correctly and efficiently.

  • Architectural drawings for a planning application are produced from measured surveys and design proposals, showing existing and proposed plans, elevations, and sections. They illustrate changes clearly, comply with local planning policy, and are prepared using CAD or BIM software to support approval by the local planning authority process effectively delivered.

  • We provide comprehensive preparation of planning submissions, ensuring all drawings, reports, and supporting documents meet local authority requirements. Our service includes coordinating consultants, addressing planning policy compliance, and presenting a strong, well-structured application. This helps improve approval chances, reduce delays, and streamline the entire planning process from start to finish.

  • The planning application is tracked from submission through validation to determination by the local authority. Regular monitoring of status updates ensures timely responses to queries or objections. The client is kept informed throughout with clear progress reports, anticipated timelines, and advice on any required amendments to support a smooth decision process.
