Heat recovery ventilation installation in Cambridge
Prices are valid for 2026 and are indicative
Here you can see what heat recovery ventilation installation in Cambridge costs on average. We explain what the price consists of and which local factors have the biggest impact.
MVHR is particularly popular in new builds and high-spec retrofits, and is increasingly specified in Passivhaus and EnerPHit projects. It is not suitable for older, draughty homes where air leakage is high — the building envelope must be reasonably airtight for MVHR to work effectively.
Installed costs for a typical UK home (3–4 bedrooms) range from £2,500 to £8,000, depending on the unit specification, number of rooms served, and ductwork complexity. VAT is 0% on MVHR systems installed in qualifying dwellings.

Cost factors
MVHR costs in the UK depend on system size, duct layout, and whether the property is new build or retrofit.
- MVHR unit (supply only): £800–£3,000
- Rigid ductwork (new build): £1,000–£3,000
- Flexible ductwork (retrofit): £1,500–£4,000
- Installation and commissioning: £500–£1,500
- Annual filter replacement: £50–£150
New build MVHR (integrated during construction) is significantly cheaper than retrofit installation, where ductwork must be routed through finished rooms. Fully commissioned systems achieve 80–90% heat recovery efficiency.
Why do prices vary?
- New build vs retrofit: New build MVHR is straightforward and cost-effective. Retrofit installations in existing homes are more complex, requiring ductwork to be hidden in ceiling voids, under floors, or in dedicated chases.
- Airtightness of the building: MVHR is only effective if the building has an air permeability below 5 m³/m²/hr (ideally below 3). Very draughty older homes are not suitable candidates.
- System size: Larger homes or those with more rooms requiring ventilation need higher-capacity units with more duct runs, increasing both material and labour costs.
- Unit specification: Premium units (Zehnder, PAUL, Systemair) offer higher heat recovery efficiency and quieter operation. Budget units may suffice for smaller applications.
- Commissioning and balancing: Proper commissioning (balancing airflows to each room) is essential for performance and Building Regulations compliance. Expect £200–£500 for independent commissioning.
- Summer bypass: Units with summer bypass allow cool night air through without heat recovery, preventing overheating in warm weather. This feature adds £100–£300.
Subsidies & incentives
MVHR installation benefits from 0% VAT under the Energy Saving Materials relief (since April 2022). No standalone grant exists specifically for MVHR, but it may be included in whole-house retrofit projects funded through the Warm Homes Local Grant or local authority energy efficiency programmes. In Passivhaus certified new builds, MVHR costs are typically included in the overall build specification.

Housing characteristics in Cambridge
Cambridge combines world-renowned historic architecture with a dense ring of Victorian and Edwardian terraces built for University staff and workers, plus extensive post-war suburban development. The city centre has some of the UK's most significant conservation area protections — any external change to properties in the central conservation areas requires careful planning. The University owns large swathes of residential property under various leasehold arrangements, which can restrict what tenants and leaseholders can do without consent. Cambridge's rapid growth as a technology and biomedical hub has driven property prices and trade day rates to near-London levels, with high demand from a professional population willing to pay for quality outcomes. The flat Cambridgeshire landscape means extensions are straightforward from a groundwork perspective, though clay soil in some areas requires deeper foundations. The market is significant for heat pump retrofits and high-specification kitchen and bathroom renovations, with homeowners investing heavily in energy-efficient upgrades alongside cosmetic improvements.
