Offset mortgage

[Loandbehold2026]

Fixed rate mortgage ending next year. Since purchasing the house, my husband has inherited some money. We have both agreed that this is likely to be needed for child with SEN, but saw the idea of an offset mortgage. I am drawn to it as it means the money is still separate and can be used when needed (I realise this would affect the repayment amounts if we did this). We have never been in the position of having savings so don’t want to mess it up. The inheritance is the same amount as our outstanding mortgage, although not sure we would put it all up, more likely to be 50-75%. Would an offset mortgage be appropriate? We will approach a mortgage advisor soon but would appreciate any thoughts. Thank you!

Possibly. We have one because DH is a contractor.

Ours is a variable rate, which I think is the norm.

Our mortgage has been paid off now, so not sure about current rates etc, but we always had an offset mortgage. We were (at the time) earning enough to regularly add to savings which refused the interest amount of the mortgage, which meant we were able to pay off the balance much quicker. At the same time we knew that if we needed money for an urgent expensive repairs it was immediately accessible.

Thank you both - other than not receiving interest on the savings are there any downsides? I know the most logical way to sort this would be to pay off the mortgage entirely but we are really concerned about only being able to release funds once we sell.

It's worked well for us. We're fully offset now but we've kept it as DH is the higher earner and we won't be retiring any time soon. It feels safer to have the obvious financial cushion.

Thank you very much indeed

We had one 15 years ago. The principle was fully offset, but we paid the full monthly amount off. It made a HUGE difference and brought down the amount we needed for our next house.

You might also consider that although you don't 'receive' interest on the lump sum, if that amount was in a regular high interest savings account, you would be paying tax on the interest, depending on whether you're a basic or higher rate tax payer. So it might actually be more efficient to use the offset reservoir.

Thank you - yes exactly my thoughts too - I think it seems so perfect that my brain is stopping me as I was paranoid there were drawbacks that I hadn’t considered! Thank you so much for taking the time to respond. It’s such a big decision and the additional responsibility of it being an inheritance means I have been quite worried about it all

The only issue is finding a good one - I’m keen to do that (although we only have a few years left) and haven’t been able to find many in the market but maybe that’s because we don’t have much left to pay off.

Personally I thought it was great. I had a reasonable amount of savings so was able to put that in the offset. It was very satisfying seeing my lump balance go down quicker. And as a result I paid off my mortgage early !

We had one until we paid off our mortgage. Probably the best financial decision I have made.

Thank you all - you have all reassured me

Ours is with Barclays btw.

Often the rate is higher than standard rates so you might be better off self offsetting by taking out a cheaper standard mortgage, making the most of ISAs and personal savings allowance. Also investing most of the money instead and getting it into S&S ISAs over the next few years as it should grow faster than a typical 4/5% mortgage interest rate.

Thank you - is the ISA allowance 20k? Was thinking that tax on interest of savings would mean it would be best to go with offset. We are also completely risk averse and husband unlikely to invest in anything that could go down as well as up! Thank you for your comment - I will look into it

We had one too. Husband got a couple of big share payouts and we used them to offset. It made a huge difference to the time it took us to pay off the mortgage, about 6 years.

We had one it was great for reducing the term of the mortgage and we really didn’t miss the interest.

It depends on the amounts, your marginal tax rates and timescales but I would have thought that full use of tax free allowances over the next 2/3 years and fact that over time investments are likely to significantly outperform cash along with the lower interest rate would mean you're likely to come out well ahead.

But you do have to be able to ride out peaks and troughs and not panic and sell investments at the wrong time.

We have done this. Its worked well. We paid off our first mortgage (25yr term at 3%) in 10 years and are now targetting paying our second off in 10 yrs too.

We used to have a first direct offset mortgage 15 years ago, similar to you used for an inheritance. The disadvantage as a pp says, is the rate will be higher than a normal mortgage and the initial setup fee may also be higher. But if are mostly offsetting then a higher rate doesn't have the same impact.
I'm not sure there are so many good offset deals these days, so you might have to hunt for one.

Worked very well for us, we offset for years and it helped us pay our mortgage off early

I think what we had would now be called an offset mortgage. It was a Virgin One account. They gave us a 'facility' at that time around £75k This was basically an overdraft that we couldn't exceed, it operated as a current account, with cheques and cards, but included our mortgage debt. Our business was Christmas heavy, so in December we would put all our takings in reducing the overdraft right down, and quite often, took us into the black. As we paid home and business bills, we gradually went into the red, hitting the lowest level in October, before the Christmas takings started to come in. For us, it was great. We didn't need to use business overdrafts, just transferred money over to our business account as and when. If we wanted a car we could buy it outright, and the interest rate, when OD was lower than car loan rates. It saved us a fortune over the years, but took a lot of monitoring to ensure we didn't overspend and not be able to pay it off by the end of the term.

Ours was a godsend we paid it off much more quickly but always knew we had access if we needed the money. We saved tens of thousands in interest

Have you looked at Sprive ?

ISA are currently 20k per year, per person

However changing to 12k per year, per person if you are not of state pension age

We've had an offset for 20 years, 100% offset most of the time. They send letters once a year saying how much interest we've saved.

Our rate is very good, a legacy discounted rate they can't throw us off. You do need to compare rates, compare your offset to best rate mortgage plus best rate isa/savings.

We do use 0% credit cards to offset our mortgage, about £40k on cards at any time, but again we could get the same benefit from putting that in best rate savings.

My biggest regret is that I didn't get into investing earlier. We'd be maybe 100k better off if we'd invested rather than offset. But obviously that is a risk too.

Our savings are for disabled DC too, it's mostly invested rather than saved.
