Bowbrook — Proposal — May 2026
Why We Are Here
TMV Compliance — Why It Matters
HARNCE was engaged following a compliance inspection at Bowbrook carried out by Total Environmental Compliance Ltd in December 2024. That inspection identified 8 failures across the installed TMV units. In addition, our own site survey identified a further 6 unprotected mixer tap outlets. This proposal sets out how HARNCE will service all 222 TMV units, address the identified defects and maintain full compliance going forward.
What is a TMV and Why Does It Matter in a Care Home?
A Thermostatic Mixing Valve blends hot and cold water to deliver a safe, controlled outlet temperature — typically 39–43°C — preventing scalding at the point of use. In a care home where residents may have limited mobility, reduced sensation or cognitive impairment, a failed TMV presents a direct and serious risk of scalding injury. Annual testing and servicing is not optional — it is a legal requirement under multiple regulatory frameworks.
Regulatory Framework
The Legal Requirement
TMV servicing in a care home is governed by a layered framework of legislation, approved codes of practice and industry standards. Non-compliance exposes the operator to regulatory sanction, civil liability and CQC enforcement action.
HSE ACOP L8 — Legionella
Approved Code of Practice requiring regular inspection, testing and maintenance of all water fittings including TMVs. Non-compliance is a criminal offence.
HSG274 — Technical Guidance
HSE technical guidance supplementing L8. Part 2 covers hot and cold water systems and mandates annual TMV servicing including fail-safe testing to the TMV2/TMV3 scheme.
TMV3 Scheme — Healthcare
Sets the standard for TMVs in healthcare and care environments. Requires annual servicing, fail-safe testing, temperature verification and full documentation by a competent person.
HTM 04-01 — Safe Water in Healthcare
NHS Health Technical Memorandum covering water safety in care premises. Sets requirements for TMV installation, maintenance and record keeping in care settings.
Health & Safety at Work Act 1974
Places a duty of care on those in control of premises to protect all persons. A scalding incident from a failed or unserviced TMV would likely constitute a breach of this duty.
Care Quality Commission (CQC)
CQC assessments cover fundamental standards of safety. Water safety compliance and TMV servicing records are an active area of CQC scrutiny in care home inspections.
The Bowbrook Position Right Now
A third-party inspection has placed 8 TMV failures on record at Bowbrook. A further 6 mixer tap outlets have been identified during the HARNCE survey that currently have no TMV protection. Until these are resolved and a structured servicing programme is in place, Bowbrook's compliance position remains exposed. HARNCE's programme closes that gap completely.

Our Recommendation
Bowbrook has 222 TMVs — 216 existing units with 8 failures on record, plus 6 mixer tap outlets identified during our survey requiring TMV installation. Add the plant room assets and you have a significant compliance programme that needs to be managed consistently. The Full service on a 3 year fixed contract delivers comprehensive, CQC-defensible maintenance across every asset, with up to 10 TMV replacements per year included, failed valves replaced on the same visit, an annual CQC compliance summary letter, and an estimated total saving of £12,348 compared to standard rates.

Section B — Recommended TMV Installations
Recommended Works — Pending Authorisation
Pending Client Authorisation
ℹ
6 Mixer Taps — TMV Installation Recommended
During the HARNCE site survey, 6 mixer tap outlets were identified that currently have no TMV protection. Following discussion with site management, it is recommended that TMV2/TMV3 approved thermostatic mixing valves are installed on each of these outlets to bring them into line with the TMV3 standard and ensure consistent compliance across the site. These 6 units are included in the 222-unit annual service count from year one of the contract. These works are subject to client authorisation and have not been included in the service contract pricing above.
| Recommended Scope | Detail | PAYG | 2 Year (10%) | 3 Year (15%) |
|---|
| TMV supply and installation (per unit) | ~60–75 mins per tap — isolate, fit TMV, test and commission | £224 | £202 | £190 |
| Total for all 6 units | Subject to site access and pipework conditions | £1,344 | £1,210 | £1,142 |
Section C — Plant Room Remedial Works
Plant Room Defects — Survey Findings
⚠
Item 1 — Plant Room Floor Leak
Significant rust staining visible on the plant room floor around the dirt separator drain and low-level pipework, indicating an active or historic water leak. Requires investigation, repair or component replacement. Left unaddressed this will accelerate corrosion of adjacent plant.
⚠
Item 2 — Corroded Expansion Vessel Pipework
The pipework connection at the expansion vessel base shows significant corrosion beyond normal wear. The condition of the fittings represents a potential system integrity risk. Investigation and likely replacement of the affected section is recommended.
| Remedial Item | PAYG | 2 Year (10%) | 3 Year (15%) |
|---|
| Floor leak investigation & repair | £500–£700 | £450–£630 | £425–£595 |

| Combined plant room remedial budget | £1,000–£1,500 | £900–£1,350 | £850–£1,275 |
