RH MEP designs, installs and maintains mechanical services for offices, retail, data centres and restaurants. One contractor from first drawing to final commissioning, so nothing gets lost between designer and installer.
Send a few details and we'll come back within one working day to talk it through or arrange a site survey.

Calculations, drawings and value-engineered options.
Our own engineers, with prefabrication where it saves time.
Testing, balancing, certificates and handover documents.
Planned maintenance and emergency call-outs.
From a single boiler swap to a full plant room. Our Gas Safe registered engineers design, install and maintain heating and hot water for offices, retail, restaurants and mixed-use buildings, including the move from gas to heat pumps.
Commercial heating is a system, not a boiler. We look at the whole thing: the heat source, the distribution, the controls and the hot water, so it runs efficiently and passes inspection.
Because we also design and install ventilation and air conditioning, we can plan heating alongside the rest of the building's services rather than in isolation.
Heating and ventilation and a plant room upgrade across an 8,600 m² headquarters, including the MEP works for a new commercial kitchen.
A new plant room, heating and ventilation for an industrial unit converted into a two-storey laboratory and office.
If your question isn't here, call 0203 633 0285 or send us a WhatsApp.
Often, yes. We survey the building and existing system first, because heat pumps run at lower temperatures and some buildings need emitter or pipework changes. Where a full switch doesn't suit, a hybrid system with heat pumps leading and boilers topping up is a common option.
Yes. We set up planned preventative maintenance contracts covering boiler servicing, gas safety checks, pumps, pressurisation and water treatment, with a fixed visit schedule.
Yes. Most of our work is in occupied offices and trading premises. We plan shutdowns out of hours and use temporary heating where it's needed.
Yes. If your heating or hot water has failed, call 0203 633 0285 and we'll arrange an engineer.
We're based in Chessington and work across London and the South East. For larger projects we also work elsewhere in the UK and in Europe.
We design heating, cooling, ventilation, gas, plumbing and electrical services for offices, retail, data centres and restaurants, from concept to construction. Because we also install, our drawings are buildable, priced realistically and coordinated with what really happens on site.
We design to the building's use and the client's budget, then value-engineer options so you can see where the money goes.
Designing the mechanical and electrical services together means plant gets the right power supplies, and containment, ductwork and pipework are coordinated before anything reaches site.
Our design work is covered by professional indemnity insurance, and the same team can carry the design through to installation.
Full mechanical and electrical design, supply and installation as a single design and build package.
Bespoke design and build of the air supply and air conditioning, with engineering solutions for a complex layout. Delivered on time.
If your question isn't here, call 0203 633 0285 or send us a WhatsApp.
Both. We take on design-only appointments, and full design and build where we install what we've designed. Many clients choose design and build so one company is responsible for the result.
Developers, main contractors, architects, landlords and tenants carrying out fit-outs.
Yes. We hold professional indemnity insurance covering our design services.
Yes. We review designs for buildability and cost, and suggest value-engineering options where they make sense.
We design and install comfort cooling and heat-pump air conditioning for offices, shops, restaurants and server rooms. As a Samsung partner, eligible Samsung systems we install come with a 7-year warranty, subject to Samsung's terms.
Most modern air conditioning heats as well as cools, so a well-designed system can replace or reduce your heating plant too.
We size every system properly, plan the pipe and condensate routes, and commission it so it runs quietly and efficiently.
Bespoke design and build of the air supply and air conditioning for a busy cycling studio. A complex design, solved with careful engineering and delivered on time.
Air conditioning and ventilation for the expansion of P&G's manufacturing facility, covering the new office and factory areas.
If your question isn't here, call 0203 633 0285 or send us a WhatsApp.
As a Samsung partner, eligible Samsung air conditioning systems we install come with a 7-year warranty, subject to Samsung's terms. We'll give you the full terms with your quote.
Yes. Heat-pump air conditioning, including VRF, provides both heating and cooling, and can be more efficient than gas heating, depending on the building and how it's used.
Yes. We plan noisy or disruptive work out of hours and work in phases so you can keep trading.
Yes. We can take over maintenance of existing systems after an initial survey.
Fresh air, heat recovery and kitchen extract for offices, retail, restaurants and workshops. We design, install and maintain systems that meet Building Regulations and keep running for years.
Good ventilation keeps people healthy and comfortable. Heat recovery means you aren't paying to heat air you then throw away.
We design ventilation alongside heating and cooling, so the systems work together instead of fighting each other.
We designed and built the ventilation for the new office and factory areas in the expansion of P&G's manufacturing facility.
Bespoke ductwork for retail units and a basement, designed and installed by our team, delivered on time and compliant with all fire standards.
If your question isn't here, call 0203 633 0285 or send us a WhatsApp.
In commercial kitchens, the gas supply should be interlocked with the extract so gas can't flow unless the ventilation is running. We install and test these systems, and our Gas Safe engineers can certify the gas side.
Approved Document F sets ventilation requirements for buildings in England. We design systems to meet it and provide commissioning records.
It depends on the system and how it's used. We set a maintenance schedule after surveying your system.
Often, yes. We survey what you have and advise whether an upgrade or replacement makes more sense.
Gas Safe registered engineers for restaurants, commercial kitchens, offices and industrial sites. From new pipework to testing, purging and certificates, done properly and on time.

If your question isn't here, call 0203 633 0285 or send us a WhatsApp.
It depends on the site. CP15 covers commercial gas safety inspections, CP16 covers tightness testing and purging, and CP42 covers commercial catering. We'll tell you which apply.
Yes. Call 0203 633 0285. If you smell gas, call the National Gas Emergency Service on 0800 111 999 first.
Yes. We plan shutdowns and connections out of hours so your kitchen or business can keep running.

RH MEP Ltd is a mechanical design and installation contractor based in Chessington. Since 2018 we've delivered complex, multi-million pound projects for commercial, industrial and residential clients, many of them national and international organisations.
Every building has a job to do, whether it's an office, a shop, a restaurant or a data centre. Heating, cooling, ventilation and gas are what keep it doing that job safely and comfortably.
We design those systems and install them ourselves. That means fewer gaps between designer and installer, fewer surprises on site and one company responsible for the result.
Energy efficiency runs through everything we do, from heat pumps and heat recovery to controls that stop plant running when it isn't needed. A more efficient building costs less to run and is better for the people in it.
Send us drawings, a brief or just a few lines about what you need. We reply within one working day.
