Our values

Our priority is to deliver unrivalled service for our clients. We recruit and retain high calibre people who work together to achieve this. Whilst our values guide behaviour and standards internally we thought you should know what is important to us because those values will also shape our interactions with you.


We value each other

We are appreciative – we freely express gratitude and look to recognise the great contributions our people make to the team and to our clients. We are also committed to looking outward at the needs around us and responding generously.


We say what we mean

We are authentic, real and have no time for politics! Amongst other things this means being candid and honest with ourselves, with each other, and with our clients. Deadlines are deadlines not vague possibilities and we expect our team to deliver.


We do what we say

We keep ourselves accountable – we measure how well we are doing as property managers and as employers, and even if it puts the pressure on, we hold each other to account in terms of the quality of what we are delivering and the deadlines.


We work better together

We are team minded – we rely on each other to get things done and we do things together. We share a sense of ownership of the vision, which means that we talk to each other about how we are going to get things done. Everyone should feel like they work with M J Mapp, not for M J Mapp, and should have some fun along the way!


We push boundaries

We are adventurous – we are passionate about reaching our full potential, personally and corporately, not just for the sake of the business but for the sake of life at its fullest. That means we look for ways to push outside of our comfort zones and develop our skills to both be better people and better at what we deliver to our clients.


Our responsibilities

Sustainability, at its heart, is about stewardship. M J Mapp believe this should form the foundation of any business. Economics cannot be decoupled from environmental or social responsibility, in fact, long term profit is dependent on productive people and a productive planet. We collaborate with our clients, suppliers and occupiers to ensure the impact of our business is managed through promoting best practice and ensuring statutory compliance.



We support SPEAR’s incredible work with young adults. The SPEAR course addresses the most common causes of under-achievement. SPEARHEAD then seeks to provide job opportunities and works with employers to place students into full time work. 75% of SPEAR graduates are still in employment or training one year later. For more information visit: Sam's story and SPEAR


The Soup Kitchen

We support The Soup Kitchen to which we donate money and resources to help them achieve their goals. The Soup Kitchen is on Tottenham Court Road and provides free hot meals, clothes and toiletries to the homeless and elderly. Two M J Mapp employees prepare and serve hot meals twice monthly and help raise money towards their work.


Environmental strategy

Proactive environmental management is one of the key requirements to ensure a sustainable business model. Its importance is underlined by a complex, evolving and expanding statutory framework that impacts how we do business internally and at all the properties under our management. We strive to improve the environmental performance of our management portfolio.


Management systems

Our environmental strategy is implemented through our certification to ISO14001, the international standard for excellence in environmental management. Our environmental management system has been developed from our environmental policy which can be viewed here.



We are committed to understanding, and acting on, the requirements of all applicable environmental law whether current or proposed. We are also committed to understanding how any other requirements of our clients, or the industry in general, impact our business. These could be client specific objectives or targets, best practice guidance, or voluntary standards all of which are assigned the same level of importance as our statutory obligations.


Strategy targets

We are committed to:

  • Increasing recycling and reducing waste sent to landfill
  • Reducing carbon emissions through active property management
  • Working with suppliers who aspire to achieving sustainability in their own operations
  • Advising our clients on how to reduce the environmental impact of their business
  • Giving back to society through our charitable partnerships

Our approach

Our approach is simple. Attract and retain the best people, focus on the needs of our clients, invest in IT, systems and processes, keep our accounting team in London and focus on one core activity to ensure that all of our resources, energy and enthusiasm are dedicated to providing an unrivalled property and asset management service.


Our service

We specialise in property and asset management. We are absolutely committed to ensuring that all of our resources, energy and passion are directed towards making M J Mapp a great business and delivering a market-leading and innovative property management solution to our clients.
