Affordable Housing

Affordable housing refers to both social rented and intermediate housing; it is designed to cater for eligible households whose needs are not met by the market. Taylor Wimpey often builds affordable housing as part of a planning obligation through a section 106 agreement.

Taylor Wimpey builds both social rented and intermediate housing, and both are mainly owned and managed by registered providers, usually housing associations. Social rented housing rents are set through the national rent regime, which are designed to be affordable to those who cannot afford market rents, whereas intermediate housing is set at prices or rents above social rent but still below market. This can include shared equity and other low cost homes for sale.

Air Source Heat Pumps

This is a system for heating a house using heat extracted from the outside air. The system, which is like a fridge in reverse, uses a heat exchanger to extract the heat which is necessarily always present in outside air.

Allowable solutions for achieving zero carbon housing

Allowable solutions provide a range of off site options to mitigate the emissions produced by development.

Biomass Boiler

This is a form of water heating which uses organic matter (often wood) as fuel.

Brown Roofs

Roofs which are partially or completely covered in locally sourced materials such as grit or rubble. This is done to stimulate biodiversity, such as insects and birds.

Building for Life

Building for Life is a ‘national standard’ for well built homes developed by the Commission for the Built Environment, the Civic Trust and the Home Builders Federation. It assesses developments on a series of 20 criteria to determine their quality.

Car clubs

These are companies/organisations which have a fleet of vehicles for members to use at their own convenience. Often the vehicles are parked in designated areas in cities/towns/housing developments etc and the members pay a certain fee according to how often they use the cars and/or how much mileage they have done.

Carbon Footprint

The term ‘carbon footprint’ is used in various ways, but in general terms means the gases emitted by an individual, organisation or process that can contribute to global warming. In calculating our carbon footprint Taylor Wimpey considers the basket of gases that is covered in the Kyoto Protocol, expressed in terms of carbon dioxide equivalent (CO2e). We have followed the reporting principles of the GHG Protocol (GGP) (Scope 1, 2 and 3) but have excluded in use emissions from the houses we build.

Code for Sustainable Homes

The Code for Sustainable Homes is a national standard developed by the Government to provide a benchmark for the sustainability of new homes in the UK. The code is measured from 1-6.

Combined Heat and Power

Also called co-generation, this is the use of a heat engine or power station to provide power in the form of electricity which simultaneously generates useable heat. Often this will be fuelled via sustainable means.

Considerate Constructors Scheme

The Considerate Constructors Scheme (CCS) encourages construction companies to demonstrate to the public their competent management, efficiency, awareness of local environmental issues, cleanliness and neighbourliness. Companies register construction sites with CCS and those sites are then monitored against a Code of Considerate Practice.

Consumer Code

The Consumer Code sets compulsory requirements for Home Builders who are registered with the supporting Home Warranty Bodies (NHBC and Premier Guarantee & LABC New Home Warranty).

Home Builders may adopt the standards of good practice, procedures and information, as detailed in the guidance against each core requirement. Where a Home Builder decides to adopt a different approach to satisfy the core requirement, they must provide a similar level of information and achieve a comparable outcome to the same level as that detailed in the guidance notes.

The purpose of the Code is to ensure that Home Buyers:

  • are treated fairly; 
  • know what service levels to expect; 
  • are given reliable information upon which to make their decisions; and 
  • know how to access speedy, low-cost dispute-resolution arrangements if they are dissatisfied.



The Ecohomes rating was the precursor to the Code for Sustainable Homes. It assessed new homes and other new build projects on their environmental performance as well as other factors such as high quality of life.

Embodied Energy

Embodied energy is the measure of energy used in the production and bringing to market of a product.

Feed in tariffs

Feed-In Tariffs are payments made to those who generate their own power using a renewable electricity system. It also pays for exporting surplus back to the grid.

Flood Risk Assessment (FRA)

This is a report required by the environment agency to determine the likelihood of a flood in a given area. The assessment is required for all new developments located in a ‘flood zone’ (measured 1-3, with flood zone three indicating the highest risk of flooding). An FRA is required by law for any sites larger than one hectare that are in flood zone 1 or higher.

Green Procurement

Green procurement is the conscious choice or purchase of products which minimise environmental harm and impact.

Green Roofs

Roofs which are partially or completely covered in vegetation. This is often done out of a concern for sustainability as, amongst other things, the roofs create a habitat for wildlife, and absorb rainwater.

Green Transport Plans

These are used by developers to encourage residents to use sustainable methods of transport and to reduce reliance on cars. These plans identify ways to encourage residents to walk, cycle and use public transport.

Greenhouse Gas

Greenhouse gas is a gas that contributes to the greenhouse effect by absorbing infrared radiation.

Greywater Recycling

Greywater recycling is the reuse of wastewater from domestic activities such as showers, washing machines and dishwashers for on site uses such as irrigation. Note that greywater differs from blackwater which is sewage containing human waste.


This was a shared equity scheme, which was funded by the Government, whereby the Homes and Communities Agency and the Home Builder had a 50/50 stake in shared equity properties sold under the scheme to purchasers fulfilling the appropriate requirements. This was up to a maximum of 30% of shared equity. The scheme ended in September 2010.

Home Zones

A Home Zone is a term used to describe a street or area which has been designed to prioritise the local community, making the street a social space rather than one which is designed primarily for cars. Often a home zone will incorporate seating areas, play areas and will prioritise pedestrians over vehicles.

Lifetime Homes

This is a series of design criteria for new homes designed to ensure they are accessible and adaptable to support the changing needs of individuals and families at different stages of life. There are 16 different criteria including door widths, potential for entrance level bed space and wide parking spaces, amongst others.


A branch of political philosophy which emphasises the local over the national. The current UK Government believes that policy decisions are more effective and democratic if they originate from the people for which they are intended. Currently the idea of localism is seen as central to the ‘big society’, a key tenet of the conservative manifesto, which is being used as an umbrella term to describe policies which devolve power to communities and promote social entrepreneurship. The aim is to have local groups drive local improvement which, the current government believes, should result in bottom up policy making rather than top down.

Localism Bill

The localism bill is an act of parliament which ‘would devolve greater powers to councils and neighborhoods and give local communities control over housing and planning decisions.’

It is the set piece legislation of the ‘big society’.

Mechanical Ventilation with Heat Recovery

This system uses heat present in stale air in wet rooms to heat up fresh air and circulate around the house. A fan is used to extract the stale air, pass the air along a heat exchanger to remove the heat, and ventilate outside. Fresh air is then drawn in and heated up using the heat extracted from the state air. This is then circulated around the house, to keep air fresh and to save on energy consumption.

Outline Planning Permission

Outline planning permission means a planning permission for the erection of a building, which is granted subject to a condition requiring the subsequent approval of the local planning authority with respect to one or more reserved matters.

Planning Obligations

Planning obligations (or S106 agreements) are private agreements negotiated, usually in the context of planning applications, between local planning authorities (LPAs) and developers. Obligations can also be secured through unilateral undertakings by developers.

Section 106 (S106) of the Town and Country Planning Act 1990 allows a local planning authority (LPA) to enter into a legally-binding agreement or planning obligation with a landowner in association with the granting of planning permission. The obligation is termed a Section 106 Agreement.

These agreements are a way of delivering or addressing matters that are necessary to make a development acceptable in planning terms. They are increasingly used to support the provision of services and infrastructure, such as highways, recreational facilities, education, health and affordable housing.

Reserved Matters

Reserved Matters in relation to an outline planning permission, or an application for such permission, means any of the following matters in respect of which details have not been given in the application –
(a) access;
(b) appearance;
(c) landscaping;
(d) layout; and
(e) scale, within the upper and lower limit for the height, width and length of each building stated in the application for planning permission in accordance with article

Secured By Design

Secured by Design is an accreditation awarded by the Police to new developments which fit its criteria of ‘designing out crime’. It focuses on crime prevention at the design, layout and construction stages of homes and commercial premises and promotes the use of security standards for a wide range of applications and products.

Sense of place

A sense of place is a term used in planning to describe the degree to which a ‘space’ is distinctive and recognisable. Often this is related to the qualities that make a place unique or ‘special’, such as architecture or landscaping.

Solar Hot Water

This is the harnessing of the sun’s energy to heat water for the home. Solar panels are installed on the roof or in the garden and the subsequent energy is used to heat the water.

Solar Photovoltaic Systems

These are solar panels, which convert sunlight into electricity. They are most often installed on roofs. Any excess energy generated can be sold back to the grid.

Solar Thermal

This is the use of solar panels to generate thermal energy (heat). This differs from photovoltaic panels which are used to create electricity.

Sustainable Homes

Sustainable homes, as measured in the UK against the Code for Sustainable Homes Standard, are homes that have been built using a process that is environmentally responsible, resource efficient and promotes health and well-being.

Sustainable Development

The Report of the Brundtland Commission 1987 defined sustainable development as “development that meets the needs of the present without compromising the ability of future generations to meet their own needs".

The Brundtland Commission’s report entitled ‘Our Common Future’ (1987) coined the concise definition of sustainable development which has been subsequently widely used. The commission, officially titled ‘The World Commission on Environment and Development’ chaired by Norwegian Prime Minister Gro Harlem, was convened by the UN to ensure future economic growth that is both ‘forceful and at the same time socially and environmentally sustainable’.

Sustainable Urban Drainage Systems

Sustainable urban drainage systems are techniques and technologies employed on site to mitigate the effects of surface water drainage discharges. This could include, amongst others, swales, basins, ponds and wetlands.

Waste Stream

A waste stream is a category of waste. The principle waste streams that Taylor Wimpey considers are those generated during the house building process; from demolition; from remediation; and soils from excavations and earthworks.

Whole House Heat Recovery

A system to continually provide a house with fresh air, which has been pre warmed via passing extracted, warm air, over a heat exchanger. This ensures a continual supply of fresh air whilst also cutting down on fuel used to heat the property.
