RIPPING out an original fireplace, adding a conservatory to a south-facing wall, or converting a loft space and including too little headroom are some of the mistakes made by owners wanting to sell their homes, accord-ing to new research.

Fitting patterned carpets or PVC double glazing in period properties are other blunders guaranteed to put off potential buyers, the study by Chase de Vere Mortgage Management found.

With the forthcoming winter expected to be tougher for sellers, estate agents are urging homeowners to spruce up their properties in order to compete.

But not all improvements are guaranteed to add value to your home, said Chase de Vere Mortgage Management managing director Simon Tyler.

Improvements most likely to make a profit include central heating, a fitted kitchen, double glazing or adding a garage.

"People too often make mistakes and invest precious cash in the wrong kinds of home improvements," said Mr Tyler.

"Sellers must put their own tastes to one side as much as possible and give buyers more space, functioning appliances and a ready-to-live-in home.

"It's crucial to meet a buyer's minimum expectations, otherwise their first impression will be one of disappointment. If it is being sold as ready-to-live-in, all of the basics must be there, and in good working order.

"It doesn't have to look like a palace but if there are clear signs of damp or if there is no working central heating, then not only will it be harder to sell but you will receive far less for the property.

"Unless somebody is looking for a property to renovate, get central heating installed, replace rotting windows and sort out any other visible maintenance jobs, and you won't have to lower your asking price.

"Many people get carried away and spend £10,000-£15,000 on a new kitchen, when they only need to spend £5,000. A relatively cheap kitchen looks just fine as long as it is fitted properly by competent workmen."
