Thanks folks - appreciate your thoughts!
By the standards of most the sums involved are trivial as I live a pretty low-income, low-expenditure existance.
Currently the £1k tax-free allowance correlates to about £20k invested at 4%, which is well beyond the amount of debt I'd be able to accrue annually on necessary expenditure (food, water, service charge & ground rent for the flat fuel, MOT & repairs for the car, socialising and any other "one off" purchases - clothing, stuff for the bike etc).
At the end of the financial year any taxable savings beyond what I expect to be required to pay off the cards in full can be moved into my ISA, and again I earn nowhere near enough to use the full £20k annual ISA allowance.
I do something similar if the opportunity arises. I can cover all my debt from savings. Currently I have a five year loan with Tesco bank that I picked up three years ago at 2%. It was a no brainer. This was to buy a car. Plus I have 0% borrowing on cards with Virgin and Tesco.
The Tesco one runs out in three weeks. It's £1600. Just last night I got a 22 month transfer at 0% and with a 1.49% fee from Barclaycard. I requested £1700, Barclaycard have me a £7500 credit limit. Cost to me is £25.33 over 22 months.
Once I have the card I cut through the magnetic strip, the chip and contactless area. I NEVER use the card again. I only ever do this for major purchases such as a car, bike or major long haul holiday.
As a pensioner with limited income but decent savings preserving my capital is important. I make the minimum monthly repayment to maximise my cash flow.
I would never do this for a household expenses, I view that as potentially living beyond one's means.
My credit rating is 969.
Thanks and yes - I'm the same with the savings and I don't see any issue in this regard if you're not spending more than you would otherwise.
I don't see why this is an issue with household expenses - why not spend someone else's money and invest your own for a bit of a return if you can borrow it for nowt...?
That's a cracking rate on the balance transfer with Barclaycard - usually the minimum I see is 3%. That was through Experian? I assume you have to be a member, and is that a paid-for service? That said I tend to go with 0% payment cards and just rack up the spending rather than paying to transfer the balance.
I also had a similar experience with Barclaycard (which was got through MSE) - the second card I got (Lloyds) had a credit limit a bit lower than the previous one (HSBC) which was fair enough as I'd since moved and my household expenditure had gone up. I expected similar from the third (Barclaycard) but they came back with a credit limit nearly twice that offered by Lloyds.
I have DD's setup to cover the minimum monthly payments on each card and once maxed out just leave the outstanding amount to drift down with these payments whilst loading up the next one, being sure to pay each off a week or so before the 0% promo period ends.
Having above 25% utilisation of your credit directly impacts your credit rating and the amount of credit you will be offered. There are a limited number of credit card companies actually providing credit as
@fossyant notes, they will want to minimise the risk exposure, so if you have more than one card with them, don't expect to get another if running credit balances. Certainly don't expect to get 0% or low interest credit cards beyond a very limited point.
Be very cautious about your own exposure, general savings accounts have very poor interest (the best I have is a regular saver at 6%) . My thought is the risk isn't worth it. You'd need a good investment (an index fund say S&P500 might get you around 10% per year at best).
Assuming a 40k per year salary (yours maybe more, but this is what I'm going with), with 2k per month recurrent expenses which can be moved to a 0% credit card. Also assuming you can get an 8% consistent return, this would yield total debt at the 2 year mark of £48000, with savings of £51800. Total additional earnings of £1,500 per year.
You'd be far better off in the long term getting a side gig and investing that money into the same investments. I went with a 2 year baseline as that's the point at which you'll likely run out of your 0% offers based on experience.
Thanks - that's interesting about the credit rating; I wasn't aware of that. On the one hand this doesn't matter a whole lot to me as it's currently decent, the mortgage has 4.5yrs to run and I'm generally very debt-averse.. thankfully other than the mortgage I'm not in a position where I have to rely on debt, so I see little risk from this angle.
I do have a "credit karma" account which gives me a score - I'll add the cards to that and keep an eye on how it changes.
Personally I'm happy with zero-risk investments at 4%; I certainly wouldn't want to open myself up to losing some of the capital in pursuit of higher returns as I can appreciate how that could be a risky strategy.
My income and outgoings are significantly less than the numbers you suggest so it's all pretty small-scale.. which at least has benefits from the perspective of tax and ISA limits. If my numbers are right the interest would be equivalent to about an additional 2.5% of my annual income.
What do you mean by a side-gig exactly? Really all I'm trying to do is play the banks for a bit of low-grief, low-risk return...
