MVHR installation in Kent

Fitting MVHR in a Kent home starts with where the unit can live and how ducts reach each room.

Our team is based in Great Barr, Birmingham, and we work throughout Kent, from Ashford, Canterbury, Maidstone, Gillingham and Chatham. The survey is free for new installations on the UK mainland, and the quote that follows is fixed and in writing.

What MVHR installation involves

MVHR works best in a home that is reasonably airtight: a new build, a deep retrofit with insulation and new windows, or a renovation where ceilings are coming down anyway. In a draughty older house it still ventilates well, but less of the heat-recovery benefit is felt because warm air escapes through gaps instead of the unit. We check this on survey and tell you plainly if a simpler system would do the job for less.

Retrofit in an occupied home

Ducts routed through the loft and down through cupboards or boxed corners. Most semis are done in 3 to 5 days.

New build or full renovation

Ducts go in at first fix before plasterboard, which is the cheapest and neatest time to fit MVHR.

Radial semi-rigid ducting

One small duct per valve from a manifold. Quieter and easier to balance than branched rigid duct in most homes.

Questions about MVHR installation in Kent

Are prices different in Kent?

Our guide prices are adjusted by region. In Kent we use South East rates, so whole-home MVHR retrofit, 1 to 2 bedroom flat is typically £4,900 to £7,650 inc VAT per home.

How often does MVHR need servicing?

Filters usually need changing every 6 to 12 months, and a full service with a clean and airflow check once a year keeps the system efficient. Clogged filters are the most common reason MVHR stops working properly.

Can MVHR cool the house in summer?

MVHR is not air conditioning, but a summer bypass lets cooler night air in without warming it, which helps take the edge off hot rooms. For real cooling you would need a separate system.

Is the survey free in Kent?

For new installations on the UK mainland, yes. The survey is free and the quote that follows is fixed and in writing. Servicing, testing and repair visits are charged, and we confirm the cost before booking.

Which rules apply to ventilation in Kent?

In England, ventilation in new and altered homes is covered by Approved Document F of the Building Regulations. Landlords also have duties under the Housing Health and Safety Rating System, and workplaces must be ventilated under the Workplace (Health, Safety and Welfare) Regulations 1992.
