Our Environmental Impact

Selwood’s unique position as a leading manufacturer of pumps for global sale and the UK’s number one pump rental solutions provider is built on decades of product development.

Our focus on innovation through technology enables us to stay ahead of the pack when it comes to increasingly stringent environmental regulations and the demands of our customers for products and solutions that minimise the impact of their operations on the environment.

Here are some of the ways we are achieving this.

HVO Fuel

Selwood is the first UK company to offer pumps that can be fuelled by vegetable oil in an industry-leading move that will significantly cut greenhouse gas emissions. All Selwood pumps which have a Stage 3B engine or above can now be run on the HVO fuel as an alternative to diesel.

In addition, all new Selwood pumps manufactured for use in the UK and around the world will be HVO-compatible, subject to individual engine manufacturers’ guidelines.

HVO is a second-generation, clean-burning fossil-free biofuel made from renewable, sustainable raw materials. It is completely interchangeable with diesel and can reduce greenhouse gas emissions by up to 90% while significantly reducing nitrogen oxide (NOx) and particulate matter (PM) emissions.

Stage V engines

Tougher restrictions on non-road machinery are coming – it is planned that after December 31st, 2021, only engines that meet Stage V criteria can be sold in the EU. The tougher Stage V limits require engines to produce lower particulate emissions than current guidelines permit, by the use of diesel particulate filters in the exhaust aftertreatment.

We are already manufacturing and supplying pumps that meet Stage V standards (Eco5), and can readily provide these to customers who need them. For example, we are pleased to be contributing pumping support for HS2, the UK’s biggest and most ambitious infrastructure project, which has raised the bar on emissions standards. Parts of the project effectively require compliance with Stage V standards this year.


SelWatch is a remote cloud-based telematics tool that  makes it easy to monitor pumps off-site, and to troubleshoot potential issues remotely from a laptop, phone or tablet from anywhere in the world. It provides live, round-the-clock updates on more than 200 elements including pump location, fuel consumption, pressure, engine temperature and servicing status.  

The system means pumps can report live feedback on fuel levels, reducing the need for refuelling visits until they are necessary. It also reports any dip in fuel efficiency so that it can be addressed immediately, saving energy, customer cost and emissions.

Greener fleet

At Selwood we are committed to minimising the impact that our operations have on the environment around us – and one way we contribute to sustainability is through the increased use of lower-emission vehicles.

Selwood’s pump rental vehicle fleet has been upgraded with the addition of six new Daf CF trucks. These are compliant with Euro-6 emissions regulations, reflecting our commitment to investing in our fleet and minimising the impact of our operations on the environment.

This means 95% of our trucks now meet the tougher Euro-6 standard while in our total fleet of 320 cars, vans and HGV trucks, 17.5% are hybrid, PHEV (plug-in hybrid electric vehicles, which can be charged from an external power source) or completely electric. Overall, 69.7% of the total Selwood fleet meet or exceeds the Euro 6 emissions standard, which is aimed at reducing levels of harmful gases including nitrous oxide and carbon monoxide as well as pollutants such as hydrocarbons.

Solutions team

Whether it’s for planned projects or emergency callouts, our teams are always working to minimise costs and environmental impact – for example by using electric-driven pumps and alternatives, such as siphoning, in our relentless pursuit of more sustainable solutions.
