MVHR for High-End Renovations in West London and Surrey

Why Premium Property Upgrades Now Require Premium Ventilation

Luxury renovations in areas like West London, Cobham, Woking, and Chobham are no longer just about aesthetics. These projects focus on performance: airtightness, energy savings, and cutting-edge comfort. Smart lighting, triple glazing, underfloor heating—these are now standard in high-end refurbishments. But there’s one system often missing until it's too late: mechanical ventilation.

Mechanical Ventilation with Heat Recovery (MVHR) systems are essential in tightly sealed homes. Without a balanced ventilation system, high-spec properties face stale air, condensation risks, and failure to meet building regulations. And in the eyes of prospective buyers, poor air quality is no longer acceptable in million-pound homes.

At ClimateWorks, we specialise in designing and installing MVHR systems in premium renovations across Surrey, West London, and the Home Counties. Our installations are discreet, fully compliant, and designed to match the quality of the build.

Why MVHR Is Essential for Luxury Refurbishments

When homeowners invest in refurbishing period or modern properties to a high specification, they often include:

• High-performance insulation
• New windows and airtight doors
• Heating system upgrades
• Open-plan extensions
• Basement conversions
• High-end kitchens and bathrooms

These features trap heat—but they also trap humidity, airborne pollutants, and odours. This can cause damp, mould, and poor air circulation unless a purpose-built ventilation solution is installed.

MVHR solves these problems by:

• Extracting moist, stale air from kitchens and bathrooms
• Supplying fresh, filtered air to living rooms and bedrooms
• Recovering up to 90% of the outgoing heat
• Operating quietly and continuously in the background

Regulatory Drivers: Building Control Now Expects MVHR in Sealed Homes

When a renovation improves airtightness below 5 m³/h·m² (a common result of high-end insulation and glazing), it’s no longer acceptable to rely on trickle vents or extractor fans alone. According to Approved Document F, mechanical ventilation must be installed—and MVHR is the only solution that maintains energy performance while complying with regulations.

MVHR installations must include:

• Ductwork sized to meet airflow rates
• Access for filter changes
• User-adjustable controls
• Commissioning and documentation to show compliance

In high-end renovations, failure to meet Part F and Part L may result in refusal of sign-off from Building Control and lower SAP scores on the EPC.

Case Study: MVHR Installation in a £2.1M Townhouse in Chiswick

A four-storey period townhouse in West London was undergoing a top-to-bottom renovation. The owners were upgrading insulation, installing triple glazing, and removing fireplaces. This left the property nearly airtight.

ClimateWorks designed and installed an MVHR system with:

• Discreet ductwork routed through ceiling voids and utility risers
• A whisper-quiet central unit in the utility room
• Supply to all bedrooms and living spaces
• Extraction from bathrooms, utility room, and kitchen
• HEPA-level filters for cleaner air in a polluted city environment
• Full commissioning and documentation provided for Building Control

The homeowners immediately noticed the difference: fresher air, no condensation, and better temperature consistency across rooms.

MVHR and SAP Performance in Renovated Properties

MVHR can dramatically improve your Standard Assessment Procedure (SAP) scores. These are used to calculate the EPC, which in turn affects resale value. In areas like Cobham, Godalming, and West London, homes with EPC B or above are far more attractive to buyers and tenants.

With SAP 10 calculations now accounting for MVHR’s impact on heat loss, properties that include heat recovery ventilation benefit from:

• Lower emissions
• Reduced heating demand
• Improved indoor air quality
• Higher EPC ratings

Bullet Summary: Key Features of High-End MVHR Systems

• Balanced, continuous ventilation
• Low-noise operation with acoustic attenuation
• Bypass mode for summer cooling
• Digital, wall-mounted controls or smart system integration
• HEPA or F7 filters for allergy control
• Full compliance with Building Regulations Part F and Part L
