Zero-VOC Paint Brands: A London Decorator's Comparison

As professional decorators working across London's finest homes, we are asked about zero-VOC and ultra-low-VOC paints more frequently than ever before. Parents preparing nurseries, homeowners concerned about indoor air quality, clients with chemical sensitivities, and environmentally conscious property owners all want to know: which zero-VOC paint is actually the best?

It is a question that deserves a nuanced answer. Having worked extensively with every major zero-VOC and natural paint brand available in the UK, we can offer a practical, decorator's-eye-view comparison that goes beyond the marketing claims and focuses on what matters: how these paints perform on your walls.

What Zero-VOC Actually Means

First, some clarity on terminology, because it is frequently misused.

VOC (Volatile Organic Compound): Carbon-based chemicals that evaporate into the air at room temperature. In paint, VOCs are responsible for the characteristic paint smell and contribute to indoor and outdoor air pollution.

Zero-VOC: The paint contains less than 5 grams of VOCs per litre. Note that "zero" does not literally mean none — it means below the threshold of 5g/L, which is the industry-accepted definition of zero-VOC.

Ultra-low-VOC: Typically below 10g/L but above 5g/L.

Low-VOC: Below the EU regulatory limits (30g/L for matt wall paints, 300g/L for glossy paints). This is a much less demanding standard.

Natural paint: Made primarily from natural ingredients (plant oils, mineral pigments, clay, lime). Natural paints are generally very low in synthetic VOCs but may contain naturally occurring volatile compounds that are generally considered benign.

Important caveat: VOC content is measured in the base paint. When colour tints are added, particularly for deep or saturated colours, VOC levels can increase. A zero-VOC base paint may become a low-VOC paint once tinted. The best manufacturers use zero-VOC tinting systems to maintain the zero-VOC claim across their colour range.

Brand-by-Brand Comparison

Earthborn

Origin: British brand, manufactured in the UK Technology: Clay-based VOC level: Less than 0.01g/L (essentially zero)

Performance assessment:

Earthborn Claypaint is one of the most distinctive paints we work with. Its clay base gives it a uniquely flat, ultra-matt finish with remarkable depth of colour. Colours appear richer and more complex than they do in acrylic paints because the clay surface scatters light differently.

Coverage: Good — typically 10 to 12 square metres per litre, which is slightly less than premium acrylic paints. Two coats are usually needed for full opacity.

Workability: Different from acrylic paints. Claypaint has a thicker consistency and a shorter working time. Decorators accustomed to conventional paints need to adapt their technique — applying in slightly thicker passes and avoiding over-brushing.

Durability: The matt finish is not as scrubbable as modern acrylic matt paints. It marks more easily and is harder to clean. This makes it better suited to bedrooms, sitting rooms, and studies than to hallways, kitchens, and children's rooms.

Colour range: An attractive range of earthy, natural tones with some bolder options. Can be colour-matched to other ranges through their bespoke service.

Price: Approximately 38 to 45 pounds for 2.5L (premium)

Best for: Bedrooms, sitting rooms, period properties, and anyone prioritising the lowest possible VOC content.

Edward Bulmer Natural Paint

Origin: British, manufactured in the UK Technology: Natural binders (linseed oil, casein) with mineral and earth pigments VOC level: Varies by product, generally ultra-low (under 5g/L for wall paints)

Performance assessment:

Edward Bulmer paints are created by a colour historian and interior designer, and they show it. The colour range is exquisite — carefully researched heritage colours with genuine historical provenance. The paints use traditional natural binders that produce a finish with the chalky, luminous quality of historical paints.

Coverage: Good at 12 to 14 square metres per litre for the emulsion range.

Workability: Very pleasant to work with. The paints flow well, level nicely, and have a slightly longer working time than some eco brands, which is helpful for achieving a smooth finish.

Durability: The emulsion range is reasonably durable for an ultra-matt finish. Not as tough as the hardest-wearing acrylic paints, but perfectly adequate for most domestic situations. The eggshell is harder-wearing and suitable for woodwork and higher-traffic areas.

Colour range: Outstanding. Approximately 168 colours, all based on historical research. Particularly strong in the heritage neutrals, soft greens, and warm earth tones that suit London period properties.

Price: Approximately 48 to 58 pounds for 2.5L (premium to luxury)

Best for: Period properties, heritage-conscious homeowners, rooms where colour quality and historical authenticity are priorities.

Graphenstone

Origin: Spanish, available through UK distributors Technology: Lime-based with graphene technology, CO2-absorbing VOC level: Zero VOC, certified

Performance assessment:

Graphenstone makes a remarkable claim: their paints actively absorb CO2 from the atmosphere as the lime carbonates over time. The science behind this claim is sound — lime does indeed absorb CO2 as it cures — though the quantity absorbed per square metre is modest.

Coverage: Excellent at 12 to 14 square metres per litre. The paint has good body and covers well.

Workability: Good, though the lime base gives it a different feel to acrylic paints. Sets slightly faster than conventional paints, so maintaining a wet edge requires a steady pace.

Durability: Very good. The lime base creates a hard, mineral surface once fully cured (curing continues for weeks after application as the lime carbonates). The cured surface is naturally resistant to mould and bacteria.

Colour range: A comprehensive range of approximately 8,000 colours through their tinting system. Deep colours may require additional coats.

Price: Approximately 42 to 55 pounds for 4L (moderate to premium)

Best for: Environmentally motivated homeowners who value the CO2-absorption claim, properties with damp or mould concerns, modern and contemporary interiors.

Little Greene

Origin: British, manufactured in the UK Technology: Advanced acrylic polymer VOC level: Intelligent Matt Emulsion at less than 2g/L; other products vary

Performance assessment:

Little Greene occupies an interesting position: it is not marketed primarily as an eco brand, yet its Intelligent range achieves VOC levels that rival dedicated eco paints. This matters because Little Greene paints are widely regarded as among the best-performing paints available in the UK, period.

Coverage: Excellent at 13 to 15 square metres per litre.

Workability: Outstanding. Little Greene Intelligent Matt Emulsion is one of the most pleasant paints to apply. It flows beautifully, levels well, and has a working time that allows for smooth, even application.

Durability: Exceptional. The Intelligent range is more durable than many full-sheen paints from other manufacturers. Intelligent Matt Emulsion can be wiped clean without marking — unusual for a matt paint. This combination of flat appearance and practical durability makes it ideal for family homes.

Colour range: Approximately 170 carefully curated colours across the Colours of England, Grey, and standard ranges. Excellent heritage colours and sophisticated neutrals.

Price: Approximately 52 to 62 pounds for 2.5L (premium to luxury)

Best for: Homeowners who want the lowest practical VOC level without compromising on performance. Family homes where durability matters. Period properties where colour quality is paramount.

Farrow & Ball

Origin: British, manufactured in Dorset Technology: Water-based acrylic with high pigment concentration VOC level: Modern Emulsion at less than 5g/L; Estate Emulsion at less than 30g/L

Performance assessment:

Farrow & Ball is the dominant premium paint brand in the London market, and for good reason. The colour quality is exceptional — that characteristic Farrow & Ball depth that changes throughout the day as the light shifts.

Coverage: Moderate at 10 to 12 square metres per litre. Farrow & Ball paints are noticeably thinner than some competitors and often require an additional coat for full opacity, particularly over dark colours.

Workability: Good but requires some experience. The thinner consistency means runs and drips are more likely if the paint is applied too heavily. On the positive side, brush marks level out well.

Durability: Modern Emulsion is reasonably durable and wipeable. Estate Emulsion is a traditional flat finish that marks more easily. The Modern range is the better choice for rooms that will see regular use.

Colour range: Approximately 150 colours, including many that have become modern classics. The Farrow & Ball colour card is arguably the most influential in British interior design.

Price: Approximately 52 to 62 pounds for 2.5L (premium to luxury)

Best for: Design-conscious homeowners who prioritise colour quality. Properties where the Farrow & Ball name carries cachet (which, in many London neighbourhoods, it does).

Auro

Origin: German, available through UK distributors Technology: Plant oil and mineral-based VOC level: Varies by product; wall paints typically under 1g/L

Performance assessment:

Auro is the choice for purists who want the most genuinely natural paint available. The range is manufactured using plant-derived ingredients wherever possible, and the company is transparent about every ingredient used.

Coverage: Good at 10 to 12 square metres per litre.

Workability: The plant oil binder gives Auro paints a distinctive feel — slightly thicker and more viscous than acrylic paints. They require a different application technique but produce a beautiful, soft finish once mastered.

Durability: Moderate. Natural paints are inherently softer than synthetic products. Auro paints are best suited to rooms with moderate traffic.

Colour range: A more limited range than the major British brands, but sufficient for most projects. Custom colour matching is available.

Price: Approximately 35 to 48 pounds for 2.5L (moderate to premium)

Best for: Clients who want the purest natural ingredients. Properties where breathability is important (lime plaster walls, heritage buildings). Homeowners with chemical sensitivities.

Dulux Trade Ecosure

Origin: Dutch (AkzoNobel), manufactured in the UK Technology: Advanced acrylic polymer VOC level: Zero VOC

Performance assessment:

Dulux Ecosure represents the mainstream industry's answer to the zero-VOC demand. As a product from the world's largest paint manufacturer, it benefits from extensive R&D resources.

Coverage: Good at 13 to 16 square metres per litre — among the best coverage rates in this comparison.

Workability: Very good. It handles like a conventional Dulux Trade paint, which means decorators require no adaptation of technique.

Durability: Good for a matt finish. Not as tough as Little Greene Intelligent, but adequate for most domestic settings.

Colour range: Full access to the Dulux colour range — thousands of options.

Price: Approximately 25 to 35 pounds for 5L (good value)

Best for: Budget-conscious projects where zero-VOC is important but premium pricing is not justified. Large-scale projects such as rental property repaints or commercial spaces.

The Professional Difference

Working with zero-VOC and natural paints requires experience and familiarity with each product's specific characteristics. A decorator who has never used clay paint will produce a poorer result than one who understands its working properties. A decorator unfamiliar with lime-based products may struggle with the faster setting time and different application technique.

At Mayfair Painters and Decorators, we have worked extensively with every brand in this comparison. We can advise on the best product for your specific situation, prepare surfaces appropriately for the chosen paint system, and apply the product with the technique it requires.
