WTS Plumbing & Heating Ltd service commercial boilers, warm air heaters and hot water plant across Cheam, covering the SM2 and SM3 districts from our head office at Jayes Park Courtyard in Ockley. This page is about planned maintenance rather than reactive call outs. We set a service regime around each asset, attend on dates that suit your trading hours or your term dates, take combustion and flue gas readings at every visit, and hand back a written record that a facilities manager can put straight in front of an insurer, an auditor or an inspector.
Cheam gives a maintenance contractor three different problems in one place. A conservation area village of inter-war parades with flats, offices and treatment rooms sitting over the shops. A red route through North Cheam where office floors sit above retail and nobody is quite sure who books the service. And the Kimpton industrial area on the Sutton edge, where warm air and radiant plant hangs in portal frame warehousing. A schedule that ignores those differences produces missed visits, refused access and gaps in the record.
What a planned service regime has to deal with in Cheam
Cheam Village has been a conservation area since 1970, and Sutton has produced a character appraisal and management plan for it. The Broadway was widened and largely rebuilt in the 1920s and 1930s, and the frontages across the village core are suburban mock Tudor with timber detailing and leaded lights, mixed with 1930s Art Deco shopping blocks. Almost every unit is a two or three storey parade with retail at ground level and flats, offices or treatment rooms above. There is no plant deck and no goods lift. Boilers, cylinders and calorifiers sit in back of house cupboards, cellars and roof voids, and the engineer reaches them through the trading floor.
North Cheam works differently. The A24 London Road is a TfL red route with controlled parking and loading bays rather than open kerbside, so a service van needs a planned place to stop. Nonsuch House puts first and second floor offices directly above a busy retail parade, with its own street entrance, and the parades around the Victoria Junction repeat the pattern. That split of ownership is what breaks maintenance records. Landlord plant and tenant plant sit in one building, isolation valves serve more than one demise, and two parties each assume the other booked the visit. On a red route there is no parking the van outside and working it out on the day.
Behind North Cheam, on the Sutton edge, the Kimpton industrial area holds the main concentration of warehouse and trade counter stock near the town. Kimpton Park Way and Kimpton Road carry named schemes including Kimpton Trade and Business Centre, Kimpton Link Business Centre, Tradeway Centre, Sutton Trade Park and the IO Centre. Stock is single storey steel portal frame with roof mounted plant, first floor trade offices and gas fired warm air or radiant heating. Units here are let and re-let often, so the heater in one bay can be years newer than next door and the service history rarely travels with the tenant. Add the secondary schools and academies, the primaries, the GP practices, the care home conversions and Cheam Leisure Centre, and the servicing calendar fills quickly.
What this covers in Cheam
A service regime set per asset, not one annual visit
We write a maintenance schedule around each appliance and the duty it actually carries. A wall hung boiler serving offices over a Broadway shop is not on the same frequency as a floor standing plant set behind a pool hall or a commercial kitchen. Intervals follow the manufacturer's instructions, the hours the plant runs and the load it carries, and the interval is reviewed against what the readings show rather than left at twelve months by default.
Combustion analysis and recorded flue gas readings
We test with an analyser on every visit and write the numbers down. Combustion ratio, flue gas temperature and operating pressures go on the record before any adjustment and again after it. On the Kimpton estate that catches a fouling heat exchanger on a warm air unit in September rather than in a February shutdown, and in a Cheam Village cellar plant room a drifting burner shows as a trend across three visits before the shop above it loses heating.
Flues, terminations and the flats above the shop
In a Cheam Village parade the flue is often the highest risk part of the system, because products of combustion travel through a building with people living or working directly above the trading floor. We check terminations, seals, joints and supports, and we look at concealed flue runs where they pass through ceiling voids, including whether inspection access exists at all. Where a termination sits on a conservation area frontage we record and maintain it rather than reach for a visible replacement.
Water quality, treatment and hot water services
Old pipework in a Cheam Village parade, where a 1930s building has been reworked demise by demise, tends to hand a modern condensing boiler dirty system water. We sample and test on service visits, check inhibitor levels, dirt separators and strainers, and report on dosing. In the care home conversions around Cheam and in leisure and pool plant the hot water side carries as much risk as the heating, so storage temperatures, thermostatic mixing valves and circulation are checked and logged alongside the boiler.
The record an insurer, auditor or inspector asks for
You receive an asset register, dated service records with the readings attached, defect notes carrying a priority, and a plain statement of what was tested. That is the pack a property manager needs for an insurance survey, a CQC inspection at a care home, a school audit or a landlord's compliance file at a village pub. We keep copies, so when the person who booked the work moves on the service history does not leave the building with them.
Warm air, radiant and roof mounted plant on the Kimpton estate
Servicing a warehouse on the Kimpton estate is a different job to servicing a boiler. Gas fired warm air heaters and radiant tubes need heat exchanger inspection, burner and fan checks, air movement and flue dilution reviewed, and roof mounted units need proper access equipment rather than a ladder. Yard space and hardstanding make that side simple, so the real constraint is trade counter and builders merchant opening hours rather than reaching the plant.
Who actually holds the duty in your Cheam building
In a single occupier unit the answer is easy. In a Cheam parade with a shop below and a flat or a treatment room above, it rarely is. The Gas Safety (Installation and Use) Regulations 1998 place duties on employers and on those in control of premises to keep appliances, pipework and flues in a safe condition, so the first question is who is in control of which part of the building. Before we set a schedule we agree in writing which appliances sit in which demise, which party receives each service record, and who pays for the visit. Where a flue, a gas meter or an isolation valve serves more than one demise we name the responsible party for that item. That single page settles more arguments about a missed service than any amount of chasing after the event.
Fitting the visit round trading hours, term dates and residents
Service dates in Cheam are set by the building rather than by our diary. Retail and food units in the village want early mornings, evenings or Sundays so an engineer is not carrying an analyser across a full shop floor. On the A24 through North Cheam we plan the loading position in advance, and where a longer visit needs kerbside on a borough road we arrange a Sutton bay suspension rather than turn up and hope. School plant is serviced in holiday shutdowns against a fixed handback date. In the care home conversions no resident goes without heating or hot water, so work is staged plant by plant.

Duties and standards that apply
- The Gas Safety (Installation and Use) Regulations 1998 place duties on employers and on people in control of commercial premises to keep gas appliances, pipework and flues maintained in a safe condition, and any work on them must be carried out by a Gas Safe registered business. WTS is Gas Safe registered heating engineers.
- Where a Cheam building includes let residential accommodation, such as a flat over a shop on The Broadway or London Road, landlord duties apply on top of that. The regulations require a safety check on relevant gas appliances and flues every 12 months, a copy of the record given to the tenant, and a copy kept for two years.
- Legionella risk in hot and cold water systems falls to the duty holder under general health and safety law. The HSE's Approved Code of Practice and its supporting technical guidance set out how to assess and control that risk. They are not statute in themselves, but an Approved Code of Practice has a special legal status: if a duty holder is prosecuted and it is shown the Code was not followed, they have to demonstrate they complied with the law some other way. That matters in care home conversions and in leisure and pool plant.
- Servicing intervals and water quality requirements written into a manufacturer's instructions are warranty conditions rather than law, and published industry guidance on system water treatment is guidance rather than a legal standard. Manufacturers refuse warranty claims where the service history has a gap or where system water was never treated, which is the risk in a Cheam parade unit that changes managing agent every few years and loses its records with the handover.
Common questions
At least once a year for most appliances, and more often for plant working hard or in dirty conditions. The manufacturer's instructions set the minimum interval for warranty purposes, and the duty to keep gas appliances and flues in a safe condition sits with the employer or the person in control of the premises whatever the warranty says. A kitchen appliance in a village pub or a pool plant room usually needs a shorter interval than a boiler serving offices above a shop, so we set frequency per asset rather than per building.
Yes, and in Cheam that is usually the only workable option. Village parade retail and food units are attended early morning, evening or Sunday, and GP surgeries with consulting rooms in use all day are normally done at weekends or outside session times. On the Kimpton estate the yard access is straightforward but trade counter hours are not, so warehouse visits tend to start early. We agree the window when the schedule is written rather than on the morning of the visit.
You get a written service record per appliance carrying the combustion and flue gas readings, plus prioritised defect notes, which is the format insurers and auditors ask for. Continuity matters more to them than any single certificate, so the value sits in a dated run of records against a named asset list. Where gas safety records are needed for let residential parts of a building we issue those separately in the proper form, and we keep copies so the history survives a change of managing agent.
Both of you, split by demise. The appliance serving a let flat over the shop sits with the landlord under the gas safety regulations, and the appliance serving the trading floor sits with the occupier as the party in control of those premises. In a Cheam Village parade the argument is almost always about shared plant, shared flues and isolation valves crossing demises, so we map those on the first visit and put the split in writing before a service date is booked.
Yes, but they sit in the fixed schedule price rather than being added later. Cheam is inside Greater London, so vans from our Ockley office pay the London wide ULEZ and heavier vehicles the LEZ. Kerbside around the village crossroads is short stay and the A24 through North Cheam is a red route with marked loading bays, so where a visit needs a bay suspension on a borough road we apply to Sutton well in advance, which is another reason to fix service dates a year ahead.
