Building water-efficient homes used to feel like a trade-off. Do the right thing environmentally, absorb the cost, hope it lands well with buyers.

That’s changing.

If current water usage patterns don’t change, the UK is heading for an ongoing water deficit of 5 billion litres per day by 2055. The regulatory response is well underway. The Environment Act 2021has set a target to reduce per person water use in England by 20% by March 2038. Ofwat has translated that into a framework that puts money back in developers’ pockets for building homes that are water efficient.

For developers in United Utilities’ North West region, here’s what that looks like in practice:

• £172 per property for incorporating standard water-saving measures – low-flow taps, showers and dual-flush toilets
• An additional £100 per property for homes fitted with a flow regulator too

United Utilities were the first water company to introduce the enhanced flow regulator incentive, it seems like a no brainer to us!

Why the Flow Regulator Is the One Worth Talking About

The water fittings incentive makes sense. Specify efficient products, evidence it, collect the payment. Straightforward.

But the flow regulator incentive is the one that tends to surprise people – because of what it doesn’t require.

A flow regulator must simply be screwed in at the water meter manifold, or plumbed inline for internal in-line meters before the meter is fitted. That’s the installation. Done.

After that, nothing changes for the homeowner. No app to download. No dial to adjust. No reminder to use less. Water flows at a regulated rate, consumption falls in the background by up to 12% a year and the home becomes permanently more efficient, without anyone having to think about it or change their behaviors

We’ve written before about why behaviour change alone can’t carry the full weight of water efficiency targets. People are busy. Habits slide. Savings that depend on constant engagement are hard to sustain at scale.

Infrastructure-led solutions are different. The saving is built in. It doesn’t drift.

For developers, that means the customer experience is completely unaffected and you still get the rebate.

The Regulatory Direction Is Clear

A government consultation launched in September 2025 proposed tightening the mandatory standard for new homes from 125 litres per person per day to 105 litres, with the optional standard moving from 110 to 100 litres.

Standards are going in one direction. Developers who build flow regulation into their standard specification now will be ahead of where regulation is heading, not scrambling to retrofit compliance after the fact.

A reduction of 20 litres per person per day could also unlock an additional 1,000 new homes for every 5,250 built, removing water availability as a block on planning consent in constrained areas. Water efficiency isn’t just an environmental consideration anymore. It’s a delivery one.

Groundbreaker’s NRv2 LoFlo®  – Designed for This

Our NRv2 LoFlo® is built for exactly this application.

• Naturally reduces consumption – no behaviour change required
• Fully compliant with current UK water regulations
• Provides whole-site backflow protection up to fluid category 2
• Costs from just £30 per unit, with a £100 incentive available per qualifying property

The ROI is immediate and the installation is simple. It fits into your standard build process rather than adding to it.

Over 90,000 homes featuring water efficiency measures have already been built or are under construction across the North-West. The scheme is established, the process is proven and the payments are real.

If you’re developing in United Utilities’ region and not yet engaging with the Environmental Incentive Scheme, you’re leaving money on the table on every plot.
