Mechanical & Public Health System Validation in Surrey and London
WTS Plumbing & Heating Ltd validates existing mechanical and public health systems before a refurbishment, extension or fit-out starts, then reports what was found in plain terms. We work from our office at Jayes Park Courtyard in Ockley, about seven miles south of Dorking on the A29, and from there we cover commercial buildings in Surrey and London. This kind of work is usually for main contractors, consulting engineers and facilities managers who need to know whether the plant already in a building can be kept, adapted or has to go. A design decision made on assumed figures tends to unravel on site, so we go and measure the real ones first.
System Validations for Commercial Buildings in Surrey
A validation starts with a survey of every mechanical and public health service in the building: heating and chilled water circuits, boilers and plant, air handling and ventilation, hot and cold water services, above and below ground drainage, and the controls that tie them together. We check what is installed against the record drawings, where any exist, test the systems, and note anything that is not performing or not compliant. Each survey is written up as a summary report with any differences from the record drawings noted, so a project team in Dorking, Reigate, Epsom or the City has one document to plan from. Where a system cannot be tested safely, for example a boiler with no gas supply or an isolated water main, the report says so rather than guessing at a figure. Some clients call this a building services condition survey or an M&E condition report. The scope is the same.
Commissioning-Style Testing of Existing Plant
We treat a validation like a commissioning exercise on a system that was never handed over properly. Flow rates are measured against the design figures, pumps and valves are checked for balance, boilers and chillers are run through their sequences, water services are tested for pressure and temperature, and ventilation is checked for air volumes. Because WTS also commissions new installations, the same engineers judge the old plant against the standard a new one would have to meet. That tells a client whether an existing system can carry a new fit-out, what needs adjusting to make it fit, and where the design should change to avoid an expensive clash later.
Efficiency & Maintenance Recommendations in Every Report
A report that only lists faults is not much use to a facilities manager with a budget to defend. Ours set out what to fix, in what order, and what can safely be left alone. Typical recommendations cover changes to a maintenance regime, remedial works to pipework and plant, control adjustments so systems stop working against each other, and the point where replacement is a better use of money than another repair. Where an air source heat pump or other low carbon plant is being considered, we say plainly whether the existing distribution system could support it. The aim is lower running costs and a longer life from the equipment already in the building. That lets a client weigh repair against full replacement before anyone commits to a design.
Reports Written by the Engineers Who Fit and Fix These Systems
WTS is a family-run firm that has installed and maintained plumbing, heating, drainage, renewables, air conditioning, electrical and mechanical systems since 2008, so our validation reports are written by people who work on these systems every week rather than by a separate survey desk. We are Gas Safe registered, F-Gas certified for refrigerant work and an NICEIC Approved Contractor, which means gas plant, cooling and electrical controls can all be assessed on the same visit. The findings give building owners and their advisers a factual basis for compliance, sustainability and investment decisions, whether the site is an office in Leatherhead, a mixed-use block in Epsom or a floor of a City tower.
Our validations and reporting work includes:
- Full surveys of mechanical and public health systems
- Commissioning-style testing of existing plant and pipework
- Performance and energy efficiency assessments
- Advice on whether existing systems can serve a new fit-out or refurbishment
- Written technical reports with findings and recommendations
- Maintenance regime, controls and remedial works advice
- Compliance checks on gas, water, drainage and ventilation services
Reporting Tailored to Your Site and How It Is Managed
No two commercial buildings run the same way, so every report is written for the site in front of us and the people who will act on it. A landlord with a multi-let office in Reigate, a contractor pricing a fit-out in Central London and a facilities manager looking after a healthcare building in Epsom each need different things from the same survey, and the report reflects that. WTS has worked as a mechanical contractor on London projects including Moor House Level 9, Cabot Square and Cannon Street, and the same engineers survey smaller premises around Dorking, Leatherhead, Ashtead, Banstead, Cheam and Cranleigh. Beyond the current faults, the report supports longer term asset planning: which plant is near the end of its life, what a phased replacement might look like, and where carbon and running costs can come down without disrupting the occupiers.

Questions we are asked about validations and reporting
A validation is a survey and test of the mechanical and public health systems already in a building, written up as a report. WTS checks heating, cooling, ventilation, hot and cold water, drainage and controls against the record drawings and against the performance a new installation would be expected to give, then sets out what is working, what is not and what should happen next.
Before any refurbishment, extension or fit-out that will rely on the existing services, and before a lease or purchase where the buyer wants to know what they are taking on. Validating first means the design team works from measured figures rather than assumptions, which avoids the common problem of discovering on site that the plant cannot serve the new layout.
A summary of each system and its condition, the test results, any differences from the record drawings noted, any compliance issues found, and recommendations in priority order covering maintenance, controls, remedial works and replacement. Reports are written for the people who will act on them, whether that is a main contractor, a consulting engineer, a landlord or a facilities manager.
No. Record drawings and operation and maintenance manuals help, and we will use whatever exists, but many of the buildings we survey around Surrey and London have incomplete or missing records. In that case the survey records what is actually installed and the report becomes the first accurate account of the systems, which is often the main reason a client commissions one.
WTS covers Surrey first from its office in Ockley near Dorking, including commercial premises in Dorking, Reigate, Leatherhead, Ashtead, Epsom, Banstead, Cheam and Cranleigh. WTS also works for main contractors in Central London and, on request, in Wimbledon, Putney and Fulham, subject to engineer availability.
Yes. WTS is a plumbing, heating and mechanical contractor as well as a survey and reporting service, so the same firm can price and carry out the maintenance changes, control adjustments, remedial works or replacement plant the report identifies. There is no obligation to do so, and the report is written so that any competent contractor could act on it.
