You can access from as little as 36 months up to 10 years of credit from our Sovereign Home Improvements finance packages. And that’s at 0% interest. On some of our windows and doors there is even 0% APR. Spreading the cost of buying new windows and doors – at the end of your payment plan you should have added thousands of pounds onto the value of your home in real terms. Apply for credit with ourselves and you will find no hidden costs either. Your initial bill is all you will ever pay.
