Building and Developing

We’re pleased to share details of our new Environmental Discount Scheme for 2022-23, effective from 1st April 2022

Leaving a lasting legacy for future generations

At Severn Trent, the nature of what we do as a company means that we have an important role to play in protecting and sustaining water as a natural resource for future generations.  We want to encourage better water efficiency in the home and help our customers to save water. We also wish to aid the prevention of flooding.

We’re therefore inviting our developer customers to be part of this legacy and in return, we’ll help you to save money on the cost of building new homes. Our new Environmental Discount Scheme could save you, as a home builder, money on both your water and sewerage infrastructure charges if you build to specified qualifying conditions. 

 

If you can show us that you are building new homes to 100 litres (per person per day) or less you could get a £280.00 discount off your clean water infrastructure charge.

Water is a precious resource that in future will come under increased demand as the population of the UK continues to grow. By thinking and acting sustainably today we can ensure there’s enough for us all tomorrow. We’d like you to help us look after the environment by reducing excess water usage in and around the home.

To aid the conservation of water, anyone building a new home within England must already comply with Part G of The Building Regulations.

 

Here are a few really important points about our scheme that we need you to be aware of:

  • Your application for the Environmental Discount Scheme must be made upfront, it requires our developer customers to opt in before accepting their quote or agreement. Late or retrospective applications cannot be accepted onto the scheme as we cannot add this discount at a later stage in the process. 
  • Your application must include water calculations, via the WRc water calculator, and a list of the itemised fixtures and fittings being installed.  Please also note that:
  • flow restrictors will not be accepted,
  • only the flow rates from unmodified fixtures and fittings, as provided by the manufacturer, must be used in the calculation,
  • fittings must comply in all cases with Regulation 4 of the Water Supply (Water Fittings) Regulations 1999, and
  • we will only accept a specific calculator, the WRc water calculator, details of which are noted below in the section entitled ‘How to apply and demonstrate that you’re building to 100 litres or less’.
  • We will honour discounts on valid quotes until the quote lapses.
  • All requotes from the 1st April 2022 will utilise the 2022-23 scheme discount values and qualifying criteria.

 

Please note the following points:

  • Opting into the environmental discount scheme at agreement stage does not guarantee fixed costs for the life of the development as this scheme is subject to annual review.
  • Any sites that have already requested the plot connections will be honoured for the validity period of the quotation, which is a maximum of 6 months from the date of issue. If the plot quotation lapses or needs to be requoted and the scheme has changed, you’ll need to provide evidence to meet the new qualifying conditions.
  • Any connections that have not been called off and will be completed after the 1st of April 2022 should be built to a maximum of 100 litres per person per day to meet the eligibility criteria and will be subject to the current discount value i.e., aligned to the latest Severn Trent Charging Arrangements and qualifying conditions and discount values of any schemes in operation at that point in time.

 

How to apply and demonstrate that you’re building to 100 litres or less

Water usage is easy to calculate using this water calculator; simply input all fixtures and fittings (e.g. types of taps, bath and toilet) that you will be installing to show the threshold you are building to.

This is the only calculator we will accept from 1st April 2022 as it follows the methodology set out in Appendix A "Water Efficiency Calculator for New Dwellings" of the Building Regulations Approved Document G, to calculate the level of water consumption for new dwellings. As a HM Government approved document, no changes, amendments or omissions are allowed to be made to any aspect of the calculations.

The installation of the efficient fixtures and fittings will help save water and protect our environment whilst also helping to reduce future water bills.

You’ll then need to complete an application form for new service connections and tell us that you would like to opt into the environmental scheme before you accept your quote or agreement. We will not be able to add this discount at a later stage in the process.

For each property that you have opted to include in the scheme, you must provide:

  • A copy of the WRC water calculator which shows the threshold that you have built to.
  • This must include the manufacturer and model number for all of the water fixtures and fittings being installed in the property.
  • Product datasheets showing the flow rates for each product that you are installing.

Regardless of the environmental discount scheme you must ensure that all fixtures and fittings installed comply with Regulation 4, of the Water Supply (Water Fittings) Regulations 1999.

If you are unable to provide this information for each property, you will not be eligible for the scheme.

In all cases we will review the information provided by you to confirm compliance with the schemes requirements and confirm the properties that are eligible for the environmental discount scheme.

 

Ensuring compliance

During 2022-23 there will be enhanced evidential requirements and compliance audits. 

Our Water Regulations team will undertake site audits to check fixtures and fittings are compliant and in line with the application form and calculations provided.

If we identify that the fixtures and fittings do not comply with the accepted calculator and specifications, we will contact you and, reserve the right to withdraw the discount and charge full infrastructure charges for properties which fail the audit and the remaining plots on site that are yet to be connected.  Where there is evidence of multiple audit failures, by a developer or agent acting on their behalf, they will not be eligible to apply for the Environmental Discount Scheme (both water and drainage) on future developments for a period of 12 months.

By opting into the scheme you are agreeing to provide access for Severn Trent to audit the fixtures and fittings installed in your properties. Failure to provide access will be treated as non-compliance and result in the same actions as mentioned above.

You could receive a discount of £124.00 if there is no surface water connection made to a public sewer

Sewer flooding is an area our customers ask us to invest in. Sewer flooding can be devasting to our customers, our communities and the environment. The use of sustainable drainage systems can help safeguard homes, streets and roads from the risk of flooding across our region caused by excess surface water.

Due to SUDs being a standard practice mandated through the planning process, we will no longer offer a discount where a surface water connection is made through the use of a sustainable drainage system. However, developer customers can receive a discount where there is no surface water connection made to the public sewer. Our Environmental Discount Scheme rewards surface water drainage solutions which prioritise infiltration or connections to a water body.

To apply please complete the application form for a new connection and ensure that you tell us before you accept your quote or agreement that you would like to opt into our environmental discount  scheme.

You must provide a drainage layout plan showing surface water drainage connectivity for the properties that you wish to claim a discount for. If you are unable to provide this information for each property, then you will not be eligible for the scheme. In all cases we will review the information provided by you to confirm compliance with the schemes requirements and confirm the properties that are eligible for the environmental discount scheme.

 

Assuring compliance

During 2022-23 there will be enhanced compliance audits. 

We will audit sites to verify details provided in the application. 

If we identify non-compliance we will contact you and, reserve the right to withdraw the discount and charge full infrastructure charges.  Where there is evidence of multiple audit failures, by a developer, they will not be eligible to apply for the Environmental Discount Scheme (both water and drainage) on future developments for a period of 12 months.

Water is a precious resource that in future will come under increased demand as the population of the UK continues to grow. By thinking and acting sustainably today we can ensure there’s enough for us all tomorrow. We’d like you, our customers, to join us in reducing excess water usage in and around the home.

To ensure the conservation of water, anyone building a new home within England must comply with Part G of The Building Regulations 2010. These regulations set out that any new home must be built to no more than 125 litres of water per person per day (pppd) and it is possible to build to as little as 80 litres.

If you can show us that you have built to 110 litres (pppd) or less you can get a £353.00 off your clean water infrastructure charge.

Water usage is easy to calculate using our water calculator – simply tell the calculator you want to build to 110 litres and when selecting your fixtures and fittings (e.g. types of taps, bath and toilet) it will provide you with a list of products to choose from which enable you to meet this threshold.

The installation of the recommended fixtures and fittings will help save water and protect our environment whilst also helping to reduce future water bills.

It’s really important that you tell us that you’d like to apply for the discount scheme and provide your evidence before you accept your quotation or agreement. We cannot add this discount at a later stage in the process. 

Ways you can tell us you’ve built to 110 litres:

You'll need to complete an application form for new service connections and tell us that you would like to opt in to benefit from the environmental scheme before you accept your quote or agreement. We will not be able to add this discount at a later stage in the process.

Please provide a copy of the results from the water calculator which show the water fittings used (confirming that you are building to 110 litres per person per day) or a copy of the Part G Compliance Report. Our Water Regulations team will undertake a selection of audits to check fixtures and fittings are compliant. 

Sewer flooding is one of our key measures for continuous improvement and it’s an area our customers ask us to invest in the most. Sewer flooding can be devastating to our customers when it happens, but the use of sustainable drainage systems can safeguard our customers’ homes from the risk of flooding caused by excess surface water.

There are many benefits of sustainable drainage:

  • Reduces the risk of sewer flooding in homes, streets and roads.
  • Less or no water is put back into our sewers, reducing pressure on our sewer network. This means less disruption in your area if we need to carry out repairs.
  • Not having a surface water connection to the public sewer and using an alternative sustainable solution, such as a soakway, means any excess rainwater collected will feed back into the natural water cycle instead of going into our sewerage system to be treated.

There are two types of discounts on offer for sewerage infrastructure charges; where no surface water connection is made to the public sewer and where a surface water connection is made through the use of a sustainable drainage system.

You can receive a discount of £124.00 if there is no surface water connection made to a public sewer or £93.00 if you surface water connects to a public sewer via a sustainable drainage system (SuDS)

Ways you can tell us about your sewer connections:

Please complete an application form for a new connection and ensure that you tell us before you accept your quote or agreement that you would like to opt in to our environmental discount scheme.

Please note: discounts against an infrastructure charge can be withdrawn or changed at any time and will be reviewed annually.
