TMV servicing and testing in Berkshire

The M4 starts a few minutes from our Chiswick office and runs straight through Berkshire. Along it you'll find hospitals, care homes, schools, airport-side hotels and big business parks, all with TMVs that need looking after.

Berkshire is a county of six unitary councils and one very busy motorway. From Slough and Windsor in the east, through Maidenhead, Bracknell and Reading, out to Newbury in the west, the towns are strung along the M4 corridor. That makes it one of the easiest places outside London for us to reach, and one with a wide range of buildings.

Business parks, offices and trading estates

Reading, Slough and Bracknell have large business parks and corporate offices, and the Slough Trading Estate adds factories, food sites and warehouses. TMVs in these buildings sit under washroom basins, in accessible WCs and in staff showers. They're rarely high risk, which is exactly why they get forgotten. A valve under a basin on a quiet floor can sit for months with barely any flow, then fail to respond when someone finally uses it.

For facilities teams, the useful thing is getting these valves onto a schedule that sits alongside the rest of the water hygiene work, with a register the next contractor or auditor can follow. TMV asset registers: what auditors want to see explains what that should look like.

Hotels near Heathrow and Windsor

East Berkshire has a lot of hotels serving Heathrow, Windsor and the business parks. Guest bathrooms usually have thermostatic showers or bath valves, and the hotel may also have TMVs on accessible rooms, spa areas and staff changing. These run all year with high turnover, so we work with housekeeping to take empty rooms first.

One thing to check: a thermostatic shower or tap shouldn't also be fed through a separate TMV. HTM 04-01 Part B advises against putting the two in series, and while it's written for healthcare, the reasoning applies anywhere. Two thermostatic devices fighting each other can give unstable temperatures.

Healthcare and care homes

The county's hospitals, community health sites, hospices and private hospitals work to HTM 04-01: TMV3 valves, commissioning records and in-service tests set by the Water Safety Group. Care homes and supported living services are spread across all six council areas, many in extended family houses in Wokingham, Windsor and the villages around Newbury. Residents' baths and showers there are the priority, and assisted baths should never exceed 44°C where vulnerable people are at risk, as HSE's HSIS6 makes clear.

Schools

Berkshire has state schools, a university in Reading and several well-known independent and boarding schools. Boarding houses, sports changing rooms and nursery washrooms are where the TMVs tend to be. We arrange visits around term dates and the school day.

Water in Berkshire

Thames Water supplies much of Berkshire, and parts of the east of the county are on South East Water. Most of the county has hard water, partly thanks to the chalk of the Berkshire Downs. Thames Water and South East Water both have postcode checkers if you want the detail for your site.

For your valves, that means steady scale build-up. We look at strainers and check valves at every visit, descale where needed, and use the results to judge whether a valve's interval should be shortened.

Getting to you

We're on the M4 almost as soon as we leave the office, so Slough, Windsor and Maidenhead are an easy run, and Reading and Newbury aren't much further. The A329(M) takes us to Bracknell and Wokingham, and the A404(M) up towards Maidenhead and Marlow. Business parks usually have parking. For town centre sites, let us know about access when you book.

Berkshire FAQs

Questions from Berkshire sites

Do you cover all of Berkshire?

Yes, all six council areas: Slough, Windsor and Maidenhead, Bracknell Forest, Wokingham, Reading and West Berkshire. We're based in Chiswick, at the London end of the M4, so the whole county is straightforward for us to reach. Sites from Slough out to Hungerford are all part of our regular work.

Do office TMVs really need servicing?

Yes, any TMV that's fitted needs testing and servicing, even in a low-risk office. Valves under basins and in staff showers drift and scale up like any other, and ones on quiet floors can stick from lack of use. Testing them also gives you supply temperature readings that are useful for your Legionella monitoring.

Can you service thermostatic showers in hotel rooms?

Yes. Thermostatic showers and bath valves work on the same principle as a TMV and scale up in the same way, so we can test and service them alongside your TMVs. We'll also check that none of them is fed through a separate TMV, which can make temperatures unstable. Visits are planned with housekeeping around occupancy.

Who supplies water in Berkshire?

Thames Water supplies much of Berkshire, with South East Water in parts of the east of the county. Most areas have hard water, which leaves scale in TMVs over time. Your supplier's postcode checker will confirm the hardness for your site, and we'll use what we find in the valves to set the right interval.

Berkshire TMVs due a test?

Send us the address and a rough valve count. We'll quote a fixed price.
