Understanding your ventilation installation quote
We believe in upfront pricing with no hidden surprises. The total cost is determined by the hardware chosen, the state of the existing electrical circuit, and the required ducting route.
From £140
Included in the installation
- Supply and fit of one dMEV unit or extractor fan in a bathroom, kitchen, utility or wet room
- Electrical connection to an existing isolator or fused spur that is already in the room
- Short extract ducting through an outside wall where the hole is already there or can be cut by us as part of the electrical visit
- Boost setup for humidity or a light switch, as the fan model allows
- A minor works certificate for the circuit we have altered
Ways to pay


- Pay by bank
- Bank transfer
- The standard price covers replacing an existing extractor fan with a dMEV unit on an intact, sound electrical supply.
- Fitting a brand new isolator switch, running fresh cable back to the consumer unit, or core drilling a new external wall outlet adds to the standard price.
- Any required repairs to damaged existing wiring found during initial testing are quoted separately before work begins.
- Current labour rate: £70 per hour.
- Materials, specialist equipment and larger project work are confirmed separately before they go ahead.

What happens on the day
Our installation visits follow a structured process to ensure your extract fan is mounted securely, wired according to electrical standards, and tested thoroughly before we finish.
- Circuit isolation and safety checksWe isolate the power supply to the room and test the existing cables at the fused spur or fan isolator switch. This confirms that the permanent live, switched live, neutral, and earth conductors are safe to receive the new unit.
- Mounting and duct connectionThe fan casing is secured to the wall or ceiling, aligning with the existing external vent path. We secure the flexible or rigid ducting to the spigot so that extracted air travels cleanly to the outside without leaking back into the room.
- Electrical termination and setupWe terminate the circuit wires into the fan terminals and configure the internal sensors. Depending on the model, we set the continuous trickle speed and adjust the humidity sensor or timer overrun to match the room requirements.
- Airflow testing and handoverWe restore power, check that the unit starts on its low-energy trickle setting, and trigger the boost function. Once steady extraction is confirmed at the grille, we provide your minor electrical works documentation.

What makes a dMEV fan different from a standard extractor fan?
A standard extractor fan only operates when triggered by a light switch or pull cord and stops shortly after. A decentralised mechanical extract ventilation unit runs continuously at an ultra-low trickle rate to maintain constant background airflow, boosting to higher power automatically when humidity rises.
Do you fit continuous extract fans in flats as well as houses?
Yes. We install dMEV units in both flats and houses across Wareham, provided there is an accessible duct route connecting the fan directly to outside air.
Will I receive an electrical certificate for the fan installation?
Yes. Altering wiring in bathrooms and wet rooms requires documented safety testing. MX2 Electrical is NAPIT registered and issues a minor electrical installation works certificate upon completing the installation.
Can you fit a dMEV fan where there was no fan before?
Yes, but this requires running a new power cable from a suitable circuit, installing a three-pole isolator switch, and creating an external vent outlet. These additional electrical and ducting requirements are surveyed and priced before the job starts.
Will the fan be noisy if it runs all the time?
Modern dMEV units use low-wattage DC motors designed for continuous background use. On their trickle setting, they produce minimal sound and are barely audible during normal daytime activities.
