Reducing Carbon. Improving Efficiency. Delivering Savings.
V1 fits a non-invasive energy-saving system that wraps around commercial heating and cooling pipework. No downtime, no process changes. Then we prove the saving from your own meter readings.
Working with care homes, hotels and commercial estates. Savings tracked live in the V1 Savings App.
Ablecare Homes — Belvedere Lodge, Bristol
Annual heating energy, indexed (baseline year = 100)
Verified 27% reduction from before-and-after meter readings. Since rolled out across all six of the group's care homes.
Sustainability is the work, not a postscript
Sustainability sits at the heart of everything we do, because it is not something we bolt onto the job. It is the job. Every project we take on exists to cut the energy a building wastes, so carbon reduction is the direct output of the work rather than something offset afterwards.
That means we can put a number on it. Every case study on this site reports a carbon reduction alongside the energy saving, because the two are the same measurement expressed differently: 94 tonnes of CO2 a year at The Headland Hotel, 26.7 tonnes at St Michael's Resort, 11.1 tonnes at The Georgian House Hotel. All of it measured from the client's own meters, not modelled.
Because the figures are measured rather than estimated, clients can use them in their own reporting. Ablecare Homes evidence their savings in their annual accounts and in their environmental and social statements directly from this data.
There is a second, quieter benefit. The system wraps around pipework you already have, so nothing is ripped out and replaced. No new boilers, no new chillers, no embodied carbon in the manufacture and disposal of plant that still had years left in it.
OH4's sustainability reporting
The V1 system is the OH4 Energy Saving System. OH4 Limited publish their own annual sustainability report, prepared against Global Reporting Initiative standards, covering their environmental, social and governance performance as the manufacturer.
Working towards EPC B. Verified efficiency measures count twice: lower consumption now, and a stronger position against the 2031 EPC B timetable for commercial buildings. What the timetable means →
Where our numbers come from
Every figure on this site comes from real customer sites: measured consumption before and after installation, weather-adjusted where the data allows. Real customers. Real meter readings. No marketing maths.
We offer trials so you can see the proof first hand, on your own meters, before committing to a portfolio-wide rollout. Ablecare Homes did exactly that: one care home first, a full year of meter readings, and only once those showed a 27% saving did they fit the remaining five.
How we verify: a consumption baseline is agreed before installation, then compared with post-install meter readings on a like-for-like basis. Clients follow the numbers live in the V1 Savings App, so the result is never just our word for it.
How it works
Survey
A free site survey. A few photos of your plant room and pipework are usually enough to scope and quote.
Install
The V1 system wraps around your closed-loop pipework. No cutting, no draining, no power supply, no downtime.
Measure
Baseline versus after, from your own meters, weather-adjusted where appropriate. Followed live in the V1 Savings App.
Verify
A clear savings report. The data, not the brochure, decides whether you roll out further.

Where the savings are biggest
24/7 heating loads
Round-the-clock occupancy makes care homes ideal candidates. Our 27% verified result at Belvedere Lodge led to a rollout across all six of Ablecare's care homes.
Heating and hot water at scale
Big heating and hot water demand, energy-hungry comfort standards. A client savings report from One Hotel Mayfair, London, documents the measured result.
Estates and portfolios
One verified building makes the case for the rest of the estate. Wearebauer Group measured a 16% reduction before deciding what to do next.
The regulatory clock is ticking
Under the MEES plans confirmed by the government in June 2026, larger commercial buildings in England and Wales are expected to need an EPC rating of B from 2031. Verified efficiency measures do double duty: lower bills now, a stronger EPC position later.
