Martin Lewis: Do you have a Power of Attorney? It’s crucial protection – not just for the elderly – and more important than a will Looking for a warm but not too yellow off white. Our house doesn't get a huge amount of natural light. I've so far spent a small fortune on testers...

Ruth Mottershead at Little Greene adds, 'Many choose to use bright white in small rooms assuming white will the room appear larger, however light neutrals and soft colours used in a tonal scheme will have the same effect whilst not appearing too stark or cold.' While white is versatile enough to work in almost any style, Marianne at Dulux, advises choosing something robust that’s easy to keep clean and pristine. ‘The finish is less important than the formulation, because white paint has the tendency to show up every little mark,' she says. 'You need to be confident that it will resist spills, scuffs and everyday wear-and-tear. Our Colour Scales collection provides a wonderful solution for creating a light fresh design scheme that gives the illusion of space, ‘Masquerade’ works beautifully alongside ‘Masquerade Mid’ and ‘Masquerade Light’ to create an elegant and welcoming scheme in a small space.' To get the best from a crisp white paint you need to put in a bit of prep. Charlotte Cosby, Head of Creative at Farrow & Ball, recommends applying a primer and undercoat to make the finish long-lasting and to fill in any small defects. If you're concerned that these extras will bump up the budget too much, then it can be useful to see what relevant home decor discount codes are currently live. A south-facing room gets a lot of natural daylight and can often be bathed in golden sunshine for a lot of the day. This means any underlying warm tones in a white paint - like yellow, red or brown - will be amplified, making a seemingly innocuous pale ivory white suddenly look decidedly yellow once on the walls.There are two killer questions to ask when it comes to choosing the right white paint', says Aaron Markwell, Colour Curator at Coat Paints. Matt and flat matt finishes hide a multitude of sins so it’s a popular choice for walls and ceilings. Satinwood and eggshell finishes work beautifully on woodwork, particularly skirting boards and doors that need a little extra coverage. The best white paint for your walls will depend both on your natural preference toward warm or cool tones, and the aspect of the room you're painting - so whether the windows face north, south, east or west.

Emma at YesColours adds, 'A south-facing room will need a cooler white to counteract the warm glow of natural daylight, any white with a hint of blue or green is ideal.' We have finally made it to the fun decorating part of doing our Victorian terrace up, except it's not very fun as I hate making decisions (I've made enough in the last 8 months to last a lifetime). We are looking for one neutral colour to paint the whole house in, then adding bits of colour in each room. Because south-facing rooms are generally the brightest in the house, a brilliant white paint can often feel quite harsh, bouncing that strong light around even more. After all, no-one wants to have to wear sunglasses in their white living room idea!

When choosing a white, always try and get a feel for its undertones, particularly when using with another colour' says Dominic Myland, CEO of Mylands. 'A clean white such as our Pure White No. 1 consists of white pigment only, so it is wonderfully uncomplicated to use. When used overall in the space, it will give a very peaceful feel – a visual palette cleanser – or it can complement any colour on the spectrum.' Flora Hogg, at Craig & Rose adds, 'When swatching whites, use a pure white as a point of reference to see the true undertone of other white. However, be mindful they can seem dramatic as first due to the contrast but trust the process. Once applied, you will still recognise it as white, but you’ll also notice how it transforms and adapts with the light throughout the day.' Cathryn Sanders at Earthborn says, 'Whites and off-whites can vary significantly depending on their undertone, with different types of natural and electrical lights impacting greatly on the perceived colour.' Cathryn at Earthborn says, 'Sun-flooded, south-facing rooms are more forgiving than their northern counterparts – so cooler tones can add freshness, especially when off-set with bright white woodwork. Whites with yellow undertones can also work well and create cosy, naturally uplifting, peaceful spaces.' When choosing the best white for your ceiling consider which option will coordinate best with your home's interiors, wall colours and furnishings,' explains Dominic Myland. 'Again pay attention to the undertones. Mylands Pure White No. 1 and Whitehall No.9 are great options available in our Marble Matt Emulsions. This is suitable for all interior walls and ceilings, including high traffic areas as they can be re-touched, wiped, washed or even scrubbed with no effect on colour or sheen.'
