You might be planning to redesign or redecorate your own home but know that money is tight. The best option would be to remortgage for home improvements. It is much better than any other kind of unsecured loan. Interest rates would be higher than a normal mortgage but lesser than an unsecured loan.
You can remortgage with your same lender or opt for second charge remortgage, to do this you will need to have sufficient equity in your property.
