Home improvements can often be very expensive. Paying for them can be difficult for some people. Some will just get a loan for the work, but others may prefer not to do this.
Paying people to do work is not normally something you can do on your credit card. You may be able to buy materials that way and if you do the work yourself this can mean things are much more affordable. Labour can be one of the biggest expenses, depending on the nature of the work. You will want a good quality job and you will know whether your skills are up to it. However, you might be able to do some part of the work, even if you cannot do all of it. You need to be aware that you will need certificates for electrical work and so it will need to be done by someone qualified.
Because you cannot normally pay contractors by credit card, then the way that you can borrow money for building work is limited. You could extend your mortgage which will mean that you are paying it back over a long period and this can make it easier to pay back but more costly. You could use a loan but these are not that easy to get these days. If it is not too expensive, you might be able to use an overdraft.
It can be best to try to save up to have the work done. This may not be easy if you are having a huge amount of work done, but if you can pay part form savings, this can make it cheaper in the long run as you are not paying for interest and bank charges on top of the cost of the work. Therefore if you can wait a while and put money aside, this can be the best thing to do.
