To allergy-proof a holiday let, focus on the main triggers: house dust mites, pet dander, mould and strong fragrances. Fit allergen barrier covers on mattresses and pillows, wash bedding at 60°C, vacuum with a HEPA-filter machine, damp-dust rather than dry-dust, keep humidity down with good ventilation, and use unscented products. No property can be completely allergen-free, but these steps make a real difference for guests with asthma, hay fever or eczema.
What are the main allergens in a holiday let?
Short-stay properties see a steady flow of people, luggage and sometimes pets, so allergens can build up faster than in a normal home.
- House dust mites live in mattresses, pillows, duvets, carpets and soft furnishings. Their droppings are a common trigger for asthma and allergic rhinitis.
- Pet dander can linger in carpets and upholstery long after a four-legged guest has left.
- Mould spores grow in damp bathrooms, around windows and behind furniture on cold walls.
- Pollen is carried in on clothes and through open windows in spring and summer.
- Fragrances from air fresheners, scented candles and strongly perfumed products can irritate sensitive airways.
How should you prepare the bedrooms?
Guests spend around a third of their stay in bed, so the bedroom deserves the most attention.
- Use barrier covers. NHS allergy guidance describes zip-up covers that fully enclose the mattress, pillows and duvet as the single most effective measure against dust mites.
- Wash bedding at 60°C. Sheets, pillowcases and duvet covers should be washed hot after every stay. Pillows and duvets that aren't encased should be washed at 60°C regularly too, if the care label allows.
- Cut back on soft extras. Decorative cushions, throws and fabric headboards look inviting but trap dust. Keep them to a minimum, or choose ones you can wash hot.
- Vacuum the mattress between guests with an upholstery tool, including the seams.
- Choose hard, wipeable surfaces for bedside tables and storage where you can.
How do you clean to reduce dust instead of spreading it?
A quick dry dust can throw allergens into the air, where guests then breathe them in. Change the method rather than the effort.
- Damp-dust every surface with a microfibre cloth that's barely damp, so dust sticks to it.
- Work from top to bottom: light fittings, curtain rails and picture frames first, floors last.
- Use a vacuum with a HEPA filter, which traps fine particles rather than blowing them back out. Vacuum carpets, rugs, upholstery and curtains.
- Don't forget hidden areas: under beds, tops of wardrobes, radiators and skirting boards.
- Clean curtains and blinds regularly. Washable curtains or wipeable blinds are easier to keep allergen-low.
How can you prevent damp and mould?
Mould thrives in humid rooms, and dust mites do too. NHS guidance suggests keeping indoor humidity between 30% and 50%.
- Check extractor fans in the kitchen and bathroom work well, and leave clear instructions asking guests to use them.
- Open windows during turnovers to air the property.
- Consider a dehumidifier in rooms that stay damp, especially in older buildings.
- Leave a gap between furniture and cold external walls so air can circulate.
- Clean small patches of mould promptly with a suitable product, wearing gloves and with the window open. Never mix bleach with ammonia or acid-based cleaners. If mould keeps returning or covers a large area, the underlying damp needs fixing.
Should you allow pets, and what should your listing say?
Pet-friendly lets are popular, but dander is a strong trigger for many allergy sufferers and can remain in a property for a long time. If you do welcome pets:
- Say so clearly in your listing so guests with allergies can decide for themselves.
- Plan a deeper clean after pet stays, including upholstery, curtains and the edges of carpets.
- Consider keeping one bedroom pet-free if the layout allows.
Whatever your pet policy, be specific and honest in your listing about the steps you take: barrier covers on beds, hot-washed linen, HEPA vacuuming, no air fresheners, and whether animals have stayed. Avoid promising an "allergy-free" stay, which no one can guarantee. Guests with allergies appreciate the detail and can book with confidence.
Which products are best for allergy-sensitive guests?
- Choose unscented or fragrance-free cleaning products and laundry detergent where possible.
- Skip plug-in air fresheners, reed diffusers and scented candles. A clean property shouldn't need to be perfumed.
- Rinse surfaces after using strong products, and ventilate well so no chemical smell lingers when guests arrive.
- Patch-test any new product on fabrics and finishes before using it more widely.
