Plain-English breakdown, so you know exactly what you're paying for, and why it matters before we set foot on site. ### What it is Ventilation systems move stale, humid, contaminated indoor air out of a building and bring tempered, filtered fresh air in — using mechanical fans, ductwork, filters and (in MVHR systems) a heat exchanger that recovers warmth from the outgoing air to pre-heat the incoming air. ### Who it's for Owners of well-insulated modern or retrofitted homes that feel stuffy or condensation-prone; restaurants, kitchens and bars needing commercial extract; clinics, salons and treatment rooms with hygiene requirements; offices and meeting rooms with CO₂ build-up; landlords meeting Building Regulations Part F. ### When you need it During renovation or extension when walls and ceilings are open; when persistent condensation, mould or stuffy air won't go away despite trickle vents; when a kitchen or bathroom extract is undersized; when CO₂ levels in meeting rooms cause afternoon-energy slumps; or when an air conditioning system is being installed and proper fresh-air provision needs designing in alongside it. ### Why it matters Modern UK buildings are sealed tight for energy efficiency — which is great for bills but terrible for indoor air quality if no mechanical ventilation is provided. Stuffy air, condensation, mould, headaches and tiredness are all symptoms of inadequate ventilation, not 'just the way the building is'. The cost of doing nothing ## What goes wrong when this is ignored. Indoor air quality is the unglamorous side of comfort cooling — but it's where most chronic 'this building feels wrong' problems actually live. ### Risks of waiting - Persistent condensation on cold surfaces (windows, external walls) leads to mould growth — health risk, decorative damage, lease and insurance issues. - CO₂ build-up above 1,000ppm in meeting rooms causes measurable drops in cognitive performance — your team isn't lazy, they're under-ventilated. - Commercial kitchen extract under-sized for grease and humidity load: ductwork fire risk, hygiene audit failures, customer complaints about cooking smells. - Trickle vents and opening windows alone don't meet Building Regulations Part F on new builds and major refurbs — building control sign-off blocked. - Air conditioning installed without proper fresh-air provision: the same stale air is being cooled and recirculated all day — comfortable temperature, terrible air. ### Common mistakes - Assuming opening a window 'fixes' ventilation — it does, briefly, at the cost of all the heat you just paid for. - Fitting a bathroom extract fan with no fresh-air make-up: it can't actually pull air out if nothing is replacing it. - Specifying a commercial kitchen hood without sizing the extract or providing matched make-up air: hood doesn't capture, kitchen fills with smoke. - Skipping the MVHR because the builder said 'trickle vents are fine' — they meet minimum code, not actual comfort. - Letting a general electrician fit a ventilation system without commissioning and balancing the air flows — system runs, but doesn't actually move the air the design says it should. Our process ## How the job actually runs. Same system every time. No improvising on your floor. 1. 01 ### Building survey & airflow design We measure room volumes, identify high-moisture and high-occupancy zones, calculate required air-change rates, and design ductwork routes through ceiling voids and risers. 2. 02 ### System specification MVHR, decentralised MEV, commercial extract or hybrid system — sized to the building, with filtration class specified for the environment (pollen, particulates, kitchen grease). 3. 03 ### Fixed quote Itemised quote: unit, ductwork, grilles, controls, commissioning, filter set, balancing and (where required) Part F compliance paperwork. 4. 04 ### Install during build or as retrofit Coordinated with the rest of the trades during build; for retrofit, we work through loft spaces and ceiling voids to minimise disruption. 5. 05 ### Commission, balance, hand over Air flows measured and balanced to design at each grille, filter set installed, controls programmed, O&M manual issued, Part F paperwork where required. What you get ## The outcomes that matter. ### Fresh air without heat loss MVHR recovers 85–92% of the heat from outgoing air to warm incoming air — fresh air at almost zero heating cost. ### No more condensation or mould Properly ventilated buildings don't grow mould on windows, in bathrooms or behind wardrobes. Solved at the cause, not papered over with bleach. ### Better-performing teams CO₂ kept below 800ppm in meeting rooms measurably improves cognitive performance and reduces afternoon slumps. ### Filtered incoming air G4 + F7 filtration removes pollen, particulates and (with HEPA upgrades) fine PM2.5 — significant quality-of-life upgrade for hay fever sufferers. ### Building Regs Part F compliance Properly designed and commissioned to meet Part F on new builds and major refurbs, with paperwork your building control officer will sign off on. ### Pairs perfectly with air conditioning Comfort cooling handles temperature; ventilation handles air quality. Together they deliver what 'good indoor environment' actually means. In depth ## Everything worth knowing before you book. The details a salesperson skips.

[01202 144008](tel:+441202144008) ### MVHR — what it is and when it's the right answer Mechanical Ventilation with Heat Recovery is a whole-house ducted system that extracts stale air from wet rooms (kitchens, bathrooms, utility) and supplies tempered fresh air to dry rooms (bedrooms, living areas). The two airflows pass through a heat exchanger inside the MVHR unit — usually mounted in a loft or service cupboard — where 85–92% of the heat from outgoing air is recovered to warm incoming air. It's the right answer for well-insulated new-builds, major refurbishments, Passive House projects and any home where condensation, stuffy air or hay fever is a real problem. It's a significant install — usually fitted during a build — but transforms how a building feels to live in. ### Commercial extract — kitchens, salons, treatment rooms Commercial kitchen extract is specified to capture and remove heat, steam and grease vapour from cooking — usually via a stainless steel canopy with grease filters above the cooking line, ducted to a high-capacity extract fan venting above roof level. Sizing is calculated against cooking line length and equipment type (gas vs electric, char-grill vs induction, etc.). Salons and beauty treatment rooms have lower-volume but more sensitive extract requirements — removing chemical fumes from colour treatments, nail products and waxing, often with activated carbon filtration. Both must be balanced with matched make-up air supply, or the extract physically can't pull. ### MEV (Mechanical Extract Ventilation) and dMEV — the simpler retrofit options MEV is a single central fan with ductwork to extract grilles in each wet room — quieter than individual bathroom fans, more reliable and easier to maintain. dMEV is decentralised — individual continuous-running fans in each wet room. Both are simpler retrofits than MVHR for existing houses where running supply ductwork to every dry room isn't practical. They don't recover heat (so you do lose warm air to atmosphere) but they're significantly cheaper to install and dramatically better than the alternative of bathroom fans you turn on and forget about. ### Filtration classes — what F7, G4 and HEPA actually mean Ventilation system filters are graded to EN 779 / ISO 16890. G4 is a coarse pre-filter (captures lint, hair, large dust). F7 is a fine filter (captures most pollen and PM10 particulates) — the standard recommendation for MVHR fresh-air intake in pollen-sensitive households. F9 captures finer PM2.5 particulates. HEPA filters (H13/H14) are used in clinical environments — they capture 99.95%+ of all particles down to 0.3 microns, including bacterial and viral aerosols. We specify filter classes against the local environment (coastal salt, agricultural pollen, urban PM2.5) and the building use. ### How ventilation works alongside air conditioning Air conditioning and ventilation do different jobs and shouldn't be confused. Air conditioning controls room temperature by recirculating and tempering the air already in the room. Ventilation brings fresh air in from outside and removes stale air to outside. A building with great air conditioning and no ventilation feels cool but stuffy; a building with great ventilation and no air conditioning feels fresh but hot. We design both together — the air conditioning handles temperature, the ventilation handles air quality, and the two systems are sized and zoned to complement each other. ### Part F, Part L and Building Regulations compliance Building Regulations Part F (ventilation) and Part L (conservation of fuel and power) together require mechanical ventilation on most new-build dwellings, major refurbishments and most commercial fit-outs. The system must be designed to a specified air-change rate per building type, commissioned with measured airflows at every grille, and signed off by an appropriately qualified person. We design, install and provide commissioning paperwork that meets both — meaning your building control sign-off doesn't stall on the ventilation package.
