This is a city which has perfected the balance between old and new – London’s heritage is treasured, but change is welcomed, and the city will continue to evolve. The Mayor of London and leaders from across the capital are seeking partners that share their values, to provide long-term investment with a bold vision.
London has systemic advantages which make it an attractive destination for investment. Whilst its systems may be perceived as complex, they are well-established, stable, and transparent:
Visible changes on the city’s skyline are testament to the strengths and successes of the planning system. London is huge, covering an area of 607 square miles and a population of over 8.5 million.
The purpose of this Guide is to provide information and support for those considering investing in the development market in London; and it covers the journey from finding a development site, to working up a scheme, to then building the scheme.
This Guide doesn’t cover the secondary investment market, and focuses on planning and development systems, as opposed to the financial regime around investment.
London’s capital investment partnership – unlocking the next £100bn
As London moves into its new 25-year development cycle, shaped by the new London Plan, London’s built environment community is working together behind a shared vision. Opportunity London’s mission is underpinned by this, including The New London Agenda and London Growth Plan.
The New London Agenda sets out a framework for best-practice city-making focusing on growth that is equitable, sustainable and prosperous. The London Growth Plan is an action-focused plan that sets out a set of clear priorities and growth opportunities for the city over this next decade.

With support from Arup, Opportunity London has developed a guide for navigating London’s complex planning and development systems. This is a tool for investors and developers to better understand the development journey in ;London, from identifying a development site through to building a scheme.
Opportunity London have a team in place to support your investment journey into and across London.
Get in touch to talk to us about how we can support you.
The UK’s central government has devolved certain responsibilities regionally, to the Greater London Authority (GLA), and locally to local government authorities. In London, there are 33 local government authorities (32 ‘boroughs’ and the City of London Corporation).
Identifying a development site for investment
In London, a unique set of government bodies, organisations, tools and databases exist to support you when looking for development opportunities. Using an agent will give the most direct and up-to-date opportunities. Speaking to private and public sector partners directly may be helpful to get a sense of longer-term opportunities (in the boroughs, speaking to the ‘Chief Planner’ is often a helpful starting point).
These are also helpful sources to identify development sites which already have planning consent. Using software and databases can be useful for identifying and contextualising opportunities with additional data.
Committed to delivering good growth in London, Opportunity London can help to put investors in touch with public and private partners to identify a development site.
Investors wanting to identify development sites themselves, or learn more about an identified opportunity, can do so through software and databases such as Molior, CoStar, Land Insight.
For more support, property agents can provide ‘live’ insight into property markets.
For investors with existing relationships, local authority contacts can provide intelligence on development priorities and growth areas. The ‘local plans’ of each borough can also be useful for highlighting areas of future growth.
Direct approaches to developers already active in the market can open-up opportunities for partnerships.
The Greater London Authority (GLA) is responsible for the oversight and delivery of the strategic growth areas for London.
Assessing opportunity and risk
There is a lot of accessible data which will help investors understand the opportunities presented by a particular development site. In the early stages of undertaking due diligence for a development site, the sources below are helpful.
The London Datastore, developed by the GLA, has many helpful data sets — giving wider statistical context to development opportunities in London (e.g. on jobs, transport, and the environment). It also has data relevant to the planning and development landscape (e.g. the number of residential planning consents per borough per year). Other data can be accessed through commissioning specialist consultants.
Making the right connections
Making the right connections within London’s property market at the right time will help ensure the success of your scheme. The London property market is made up of public and private stakeholders, who are involved at different stages of a scheme.
Early engagement with potential collaborators, partners, funders, enablers, consultees, and consenting bodies is a good way to reduce risk (knowing who you need to engage with is highly dependent on your development site and potential scheme).
Some of the most prominent players in London’s property market are grouped into these main categories.
Benefits of the UK’s system
The UK’s planning consenting system is a discretionary, plan-led system, which differs from zoning-systems found in other parts of the world.
Each London borough publishes a succinct and up-to-date plan which provides a positive vision and a framework for addressing housing needs and other economic, social and environmental priorities — this is called a ‘Local Plan’. All planning decisions regarding developments are made on a case-by-case basis in line with the area’s Local Plan.
In the three-month period from July–September 2023, 85,600 planning applications were decided across the UK, with 86% of these being granted. In London, in the same period, 14,700 planning applications were decided, with 79% of these applications being granted.
The system has several benefits for investors, including:
Key Planning Considerations
Provision of new homes is a major public benefit. Residential developments of more than 9 homes are required to contribute a proportion of new homes as ‘affordable’. There are a variety of types of affordable homes, and the requirements vary from borough to borough.
Great emphasis is placed on design quality, and development will need to demonstrate how it will improve the quality of the local area, both visually and functionally. Design quality is often independently reviewed during the planning application process.
London is world-famous for its heritage. Preserving this is important. Accordingly, development in or close to world heritage sites, conservation areas, or listed buildings will need to be carefully designed to preserve or enhance these assets.
London’s parks and open spaces are special. Many of London’s open spaces and undeveloped land are designated as protected — for example, Metropolitan Open Land or Green Belt. Developing such land is only permitted in exceptional circumstances.
The Mayor is committed to ensuring London leads the way in tackling climate change by making London a net zero-carbon city by 2030. Therefore, development must be environmentally sustainable, meet net zero carbon targets, not worsen air quality, enhance urban greening, and mitigate against urban heat. Proposals must also demonstrate a net gain in biodiversity on the development site.
There are planning policy requirements for affordable housing and contributions towards social infrastructure. The overarching parameters for these are set out in the London Plan, but specific requirements are set by the boroughs in their Local Plans.
Pre-application activities
When working up a proposal, pre-application discussions with the Local Planning Authority are recommended to understand the planning policy context. Applicants can enter into Planning Performance Agreements; these are a framework for agreeing timescales, actions, and resources for handling planning applications. Highly experienced and skilled planning consultants can navigate the pre-application process.
In London, for development involving 150 or more homes, or over 25m in height, it is recommended that consultation is also undertaken with the London Mayor, who will be formally consulted on a planning application.
It is also advisable to speak with relevant government agencies or statutory bodies where applicable. For example, if your development site is at risk of flooding, pre-application advice can be sought from the Environment Agency. If your development requires alterations to infrastructure such as sewers or power cables, then water and power providers (such as Thames Water and National Grid) should be consulted.
It is also important, at an early stage, to engage local communities and elected politicians to secure popular and political buy-in for your scheme. Early engagement reduces the risk of objections arising at the planning application stage.
Planning Application Process
Once you have worked up a scheme, a planning application will be submitted. Applications are categorised into ‘minor’ or ‘major’ applications, depending on their size. Generally, major applications take longer to be determined, have a greater involvement of statutory consultees, require a higher degree of environmental assessment, are more likely to be decided by the Planning Committee, and attract a greater level of political and public attention. For major schemes, the risk arising from public and political objections can be mitigated by engagement at the pre-application stage.
The granting of a planning permission is a key milestone, at which point an investor may choose to either sell the land or implement the planning consent. It is important to note that some types of development do not need a traditional planning permission and can proceed through Permitted Development Rights; this includes conversion of some buildings (such as offices and shops) into residential use in certain locations, with a streamlined planning process.
Implementing your permission
Once planning permission has been secured, you will need to understand the requirements of the permission and any associated risks when deciding whether to retain or sell on the development site.
There are three main considerations:
A planning permission will include a suite of conditions.
These are likely to require the submission and approval of further information prior to certain stages of construction commencing.
Conditions may also stipulate requirements — for example, the hours of operation of any commercial use.
Planning obligations are legal obligations designed to mitigate the impacts of a development proposal (e.g. by funding additional nurseries, medical and community centres to support new and existing communities). Planning obligations are commonly referred to as ‘Section 106’, ‘S106’, or ‘developer contributions’.
The boroughs’ expectations for planning obligations are set out in the Local Plans. Obligations generally take the form of financial contributions. Another form of planning obligation is the provision of affordable housing — this is a policy requirement on most residential developments in London.
The Community Infrastructure Levy (CIL) is a charge which can be levied by local authorities on new development in their area. It is an important tool for local authorities to use to help them deliver the infrastructure (e.g. transport, flood defences) needed to support development in their area.
Some types of development are exempt from paying CIL.
Tried and tested routes to delivery
There are well-trodden paths to bring a development project to fruition in London. Delivery routes will always depend on the partners involved, their skills, capabilities and appetite for risk and reward. To this end, bespoke partnership and delivery arrangements are common — and specialist advisors can help to shape the associated governance, legal, and financial arrangements. However, many of these bespoke arrangements sit within the following broad categories.
Building the scheme — Delivery Options
Investors act as funders and development managers and are responsible for delivering the development, employing specialist contractors and advisors where required. The investor leads design and delivery, including the initial design work, securing planning permission, letting and monitoring build contracts, achieving practical completion, and finally implementing marketing and letting strategies.
The project is delivered in partnership with others who contribute land or funding as equity. Partnerships often include developers, boroughs, or specialist providers such as housing associations, who deliver and manage affordable housing. Bespoke partnership arrangements govern the roles, responsibilities, and risk allocation of each organisation.
Sale of land, by tender or on the open market. At appropriate milestones (such as achieving planning permission), an investor could dispose of a development site to a party equipped to deliver development. Equally, many choose to acquire land with the benefit of a planning permission to reduce risk.
The investor is responsible for providing funding, while delivery is outsourced to a partner. This could be through a development agreement or a development management agreement, whereby other specialist parties take responsibility for the development and delivery of the scheme. Forward funding arrangements are also common in the London market.
How to find and optimise project finance
Investors might be seeking to pull together a package of funding for a project (or projects); advisors will be able to support in identifying other appropriate sources of funding, though some of the key starting points are summarised below. Advisors can also support in refining development strategy to optimise a scheme’s viability and return to investors.
Given the range of tax, insurance, and currency exchange considerations, it’s worth selecting a panel of advisors across a range of different specialisms (tax, legal, development strategy, and so forth) to identify and manage areas of risk.
Procuring contractors in London
Procurement of contractors will always be bespoke to a development site and the investor’s requirements, but there are three pathways commonly utilised by investors in the London development market.
Procurement routes will depend on project complexity, time constraints, budget, and client appetite for risk. An advisor can help with selecting a suitable procurement route.
This route involves separate design and construction teams reporting directly to the client. Once the design team produces detailed project specifications, the project is put out to tender for contractors who bid based on the provided specifications. The client bears much of the design, construction, and cost risk.
There are various forms of D&B procurement, but typically the client procures a single contractor to undertake design and construction. The contractor becomes your main point of communication, and they take on most of the delivery risk. However, the client manages design until the contractor is appointed. The contractor bears much of the design, construction, and cost risk.
This method usually tenders out individual trade packages, enabling investors to directly appoint separate contractor and subcontractor teams. A construction management team could be appointed to provide input on constructability and cost, particularly during the early design phase. The client bears much of the design, construction, and cost risk, but will also reap any rewards.
Public-private partnerships are an established and successful delivery route in London
In London, there are many instances of public-private partnerships successfully implementing high-quality developments. Selecting the appropriate partner is essential and necessitates a deep comprehension of what each party wants and needs. Public sector bodies are subject to specific procurement regulations. Advisors can provide detailed advice on identifying the right partner to meet your needs, and the formal procurement process to instigate the partnership.
Investors can form partnerships with public-sector bodies in a variety of ways:
Project-specific partnerships
This model involves a bespoke arrangement for the delivery of a specific development site. The sharing of risk and reward between public and private partners is governed through contracts, and sometimes through the establishment of a new corporate entity. Equity contributions (often including a land contribution) and delivery responsibilities will vary according to each partnership.
Strategic partnerships
Some local authorities or public sector entities may secure a strategic development partner, providing opportunities for development and investment in the longer term. For example, TfL (more specifically, its property arm Places for London) has had a long-term partnership with Grainger to deliver Build to Rent homes.
Equally, a number of Business Improvement Districts (BIDs) in London — business-led organisations that work collaboratively with the GLA and boroughs — are seeking partnerships with investors.
There are also sub-regional partnerships whereby a number of boroughs come together, seeking to scale investment opportunities.
