MVHR Installation Services in Basingstoke – A Complete Guide for Homeowners and Developers

Why MVHR Installations Are Growing Across Basingstoke in 2025

Across Basingstoke, homeowners and developers are rethinking how they ventilate their properties. As homes become more airtight due to insulation upgrades and stricter energy standards, the demand for mechanical ventilation with heat recovery (MVHR) is growing fast.

Whether you're building new homes in Kempshott or renovating a family property in Hatch Warren, MVHR systems offer long-term benefits in indoor air quality, energy savings, and compliance with the latest Building Regulations. With rising awareness of poor indoor air and moisture-related problems, local demand has never been stronger.

This blog explains everything you need to know about MVHR installation in Basingstoke—from how systems work and what regulations apply, to installation steps, servicing, and why ClimateWorks is trusted by property owners throughout Hampshire.

Why MVHR Is Relevant in Basingstoke Today

Basingstoke is expanding rapidly. New developments across Manydown, Hounsome Fields, and Chapel Hill are delivering hundreds of homes, all subject to updated regulations for energy performance and ventilation.

At the same time, existing homeowners in Brighton Hill, Lychpit, and Chineham are investing in property upgrades—insulation, triple glazing, and airtight retrofits—that reduce natural airflow.

MVHR systems offer a solution to this by:

• Continuously supplying fresh, filtered air to all living spaces
• Extracting stale, moist air from kitchens, bathrooms, and utility rooms
• Recovering heat from outgoing air and transferring it to incoming air
• Reducing condensation, mould, and airborne pollutants
• Lowering heating bills by recycling up to 90% of heat energy[1]

In a climate where homes are better sealed but more prone to overheating or moisture buildup, MVHR provides balance and control.

How MVHR Works and What It Includes

An MVHR system consists of:

• A central unit (usually located in a loft or utility space)
• Ductwork running to key rooms throughout the property
• Two airflows: one that extracts stale air, and one that supplies fresh air
• A high-efficiency heat exchanger to retain warmth from outgoing air

Air is drawn from wet rooms (bathrooms, kitchens) and replaced with filtered outdoor air routed to habitable spaces (living rooms, bedrooms). The key feature is the heat recovery process, where energy from extracted air is reused to warm incoming air—reducing the load on your boiler or heating system.

Basingstoke Installation Case Study: New-Build Home in Kempshott Rise

A couple building a 4-bedroom detached home in Kempshott Rise contacted ClimateWorks during the early design stage. Their architect specified a highly insulated, airtight building fabric compliant with the Future Homes Standard, and they needed a ventilation system that matched their energy goals.

Key priorities:

• Meet Approved Document Part F and Part L of the Building Regulations
• Achieve SAP targets for ventilation and thermal performance
• Avoid wall-mounted extractor fans and noisy background ventilation
• Ensure excellent indoor air quality for a family of four

Our MVHR solution included:

• Full system design using SAP calculations and air change rate assessments
• Installation of a high-performance MVHR unit with summer bypass and CO2 sensor compatibility
• Rigid ducting throughout the property, routed through ceiling voids
• External terminals mounted with weatherproof cowlings
• Commissioning report completed and handed over per regulations

The result was a quiet, energy-saving system that integrated seamlessly into the property. The client also benefited from reduced heat loss, stable humidity, and filtered air with fewer allergens.

UK MVHR Regulations You Need to Know

Installing MVHR in Basingstoke requires compliance with key UK regulations:

Approved Document F – Ventilation

• Homes must provide “adequate means of ventilation”
• MVHR systems fall under System 4 (Continuous Mechanical Supply and Extract with Heat Recovery)
• Airflow rates must meet minimum extraction and supply rates for each room type[2]
• MVHR must be commissioned, tested, and balanced upon completion

Approved Document L – Conservation of Fuel and Power

• MVHR helps meet thermal efficiency and SAP ratings
• Heat recovery efficiency must be measured and included in energy modelling
• All systems should have low specific fan power (SFP) to reduce running costs

Part O – Overheating Risk in New Homes

• Introduced in 2022 to limit indoor overheating risks
• MVHR with summer bypass helps reduce overheating and ensure comfort

Installation Process: How MVHR Is Installed in Basingstoke Homes

At ClimateWorks, we install MVHR systems across both new and existing homes in Basingstoke and surrounding areas.

Step-by-step process:

1. Initial consultation and property survey
2. System design using floor plans, room volumes, and SAP targets
3. Ductwork routing planned for minimal visual impact
4. MVHR unit installed in loft, plant room, or utility area
5. Ducts connected to extraction and supply grilles
6. External intake and exhaust terminals mounted
7. System commissioned, balanced, and airflow rates documented

Most installations are completed within 3–5 working days. For new builds, we coordinate with your contractor to install ductwork during the first fix.
