As expected, the decision by Santander to increase its standard variable mortgage rate (SVR) has received short shrift from the media, but claims and accusations aside, the move should act as a wake-up call for other borrowers currently sitting on SVR.
The 300,000 or so customers of the UK arm of the Spanish banking giant will be unhappy to learn that their monthly mortgage repayments will take a bigger slice of their disposable income from October, but for some at least there will be the option of moving to a cheaper fixed or tracker option elsewhere.
Santander is increasing its SVR from 4.24 per cent to 4.74 per cent, which is just shy of the market average of 4.77 per cent.
This isn't the first instance of SVR increases this year, with Halifax, Co-operative Bank and Clydesdale/Yorkshire Banks already increasing rates in May, and I fear that with increasing capital requirements, higher regulatory costs and pressure on profit margins, Santander won't be the last lender to hike costs before 2012 is out.
Standard variable rates vary widely between mortgage lenders, with ING coming in at just 3.5 per cent and First Direct 3.69 per cent while at the other end of the scale Kent Reliance and Nottingham Building Society charge a much steeper 6.08 per cent and 6.14 per cent respectively.
The recent spate of SVR increases is a stark reminder to consumers that unlike a tracker product, the interest rate can move up or down even if there is no change in base rate.
Many commentators suggest simply switching your mortgage to a more appropriate and cheaper product. However it's not as black and white as that.
There are a number of factors to bear in mind with SVRs and it's not a case that one solution fits all for borrowers who are affected by these rate hikes.
For example, customers with a small mortgage balance and/or just a few years remaining on the term of their home loan may be just as well staying put due to the cost of switching.
Product fees and in some cases valuation and legal charges associated with a new mortgage mean that it's not always financially viable to look elsewhere.
Another thing to take into account is that the SVR is the same whatever your loan-to-value may be.
If you only have a 10 per cent deposit or less then the SVR you are currently being charged is likely to be cheaper than the latest best-buy fixed or discounted deals, whereas if you have 40 per cent equity you should be able to remortgage to a better option.
The ability to take your mortgage custom elsewhere will also depend on the state of your credit status. If your credit rating has deteriorated during the time you've had your current mortgage you may find it difficult to transfer to a new home loan elsewhere due to the strict lending criteria enforced by lenders these days.
The cost impact for someone with £50,000 on a Santander SVR mortgage with 20 years to run will be an extra £13.50 per month, but by switching to a five-year, fixed rate of 3.59 per cent and no fee with Post Office (assuming a 25 per cent deposit) you could cut your existing monthly payment from £309.35 to £292.30, saving £17 per month, or over £30 per month when compared with the higher SVR payments which kick in from October.
As I mentioned earlier, the cost savings are more substantial for those with larger mortgages. If you're borrowing £150,000, Santander's 0.5 per cent SVR hike will cost you an extra £40.47 per month from October
However, assuming a 25 per cent deposit and 20 years still to run, transferring to a tracker mortgage at 3.69 per cent and no fee from First Direct could save you £43.39 per month on your existing payments and £83.86 per month when compared with the increased 4.74 per cent Santander SVR.
The financial benefit will depend on the size of your mortgage balance and the term remaining, but you'll also need to take into account the product fees on a new mortgage as in some cases these can be well into four figures and wipe out most of the potential savings.
