Heat recovery ventilation installation in Birmingham
Prices are valid for 2026 and are indicative
Here you can see what heat recovery ventilation installation in Birmingham 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.
Local considerations in Birmingham
Average (baseline)UK's second-largest city — diverse housing stock and competitive trade rates. Strong demand driven by growing population.
Housing characteristics in Birmingham
Birmingham is the UK's second city and has one of the most diverse housing stocks in England. Inner Birmingham (Moseley, Balsall Heath, Kings Heath) contains Victorian and Edwardian terraces comparable to those in Manchester and Leeds, often built as artisan housing for factory workers. The inter-war period produced a huge wave of semi-detached housing across Solihull, Sutton Coldfield, and the outer suburbs — the classic 1930s British semi, with cavity walls (now suitable for insulation), bay windows, and modest rear gardens. Post-war council estates in Erdington, Chelmsley Wood, and Northfield represent a significant portion of the housing stock. Birmingham's substantial South Asian community has driven a distinctive renovation culture, with particular demand for kitchen upgrades, extensions, and multi-generational living modifications. Trade rates are competitive — typically 10–20% below London — and the large construction workforce trained through the city's apprenticeship programmes keeps labour supply strong. The Legacy Development corridor from the 2022 Commonwealth Games has catalysed significant residential investment in east Birmingham. ECO4 uptake has been high in Birmingham given the city's significant proportion of lower-income households in older, poorly insulated housing.
- Mix of Victorian terraces, inter-war and post-war semi-detached
- Competitive trade rates — good value for renovation projects
- Large proportion of 1920s–1960s semi-detached housing in outer suburbs
- City-centre regeneration driving high-spec apartment conversions
- standard Building Regulations and planning requirements
- broad selection of local and regional contractors
- typical scheduling availability throughout the year
- 0% VAT on MVHR as an energy saving material
- Building Regulations Part F compliance required — airtightness testing recommended
- Commissioning and balancing essential for performance — do not skip this step
- Not suitable for homes with air permeability above 5 m³/m²/hr
