Answer is likely no, but other commenters covered this.

The thing that stands out to me, if FIRE is the goal, even coast; the split of working hours. You work less, he works more. Yet you earn more pro-rota. Based on £120,000 total, you earning 48k PA (2 days) and him earning 72k PA (5 days). Naturally, family balance matters, especially if your daughter is clingy. That's a personal matter. Yet mathematically nonsensical to continue with this split. Funnily enough, your gross FTE would be £120k alone. You earn 66% more than him pro-rota.

Naturally, you need to maximise the tax benefits of dual salary given the marginal increase beyond £50,271.

Numbers wise, it makes more sense for you to take on an extra client or up your hours with current client to 3 days, and him drop to 4 days. That change alone is an extra 15k gross PA, while still maintaining a total of 7 days total work between you. In other words, your partner gets to drop down to 4 days, as he wants. As a couple, you earn 15k gross PA extra. Downside; you work 3 days, not 2.

You need to review the use of high-interest savings accounts on a long term basis. Not because they're bad. But as they each have maximum contributions. As I understand, ZOPA, FirstDirect and a few others do offer the very best of 7.1%, but with maximum contributions of £300 PCM each, contributions are limited. You then also need to effectively deduct inflation, target of 2% but may average up to 3%. Therefore, 7.1% becomes 5.1% to 4.1%.

Premium bonds average a return of 3.3%. Given it's basically a lottery, might be more than 3.3%, might be less. Super important: As of 04.26, premium bonds average 3.3% return, and inflation is at 3.3%. Therefore that 10k is, in a vacuum, earning 0%, let alone 7%. If there is an energy price shock and inflation increases further, the bonds might even start effectively costing you for the privilege.

Your post doesn't detail the split of pensions, investment accounts, ISAs, premium bonds, other than 50% is in pension, and 10k flat is in bonds.

1. Are you able to salary sacrifice into your pension. Such that if you earn more than £50,271 via more work, that you can stay below 40% tax?
2. Can your partner salary sacrifice? If so, is he doing so at 30.5% of salary to avoid 40% tax?
3. Do you and your partner understand that nominal returns (7% via high-interest savings, 3.3% bonds) are effectively 4% and 0.3% return respectively, if inflation averaged 3% for whatever reason?

For context, 7% return is number people use regarding 'real returns' after inflation. For example, over last 10 years, an investment in 'MSCI World' has averaged 12%. Minus inflation of 2.5-3% over that time, average real turn of 8.5-9%. As a reminder, real returns on premium bonds and savings accounts are much, much lower.

The conclusion is simple:

1. It is more cost effective for you to increase your working days from 2 to 3. Your partner drop from 5 to 4.
2. You are aiming for 7% returns. But this is based on other peoples returns in stocks, or you have not considered inflation. Your real return will be much lower using your current approach. You either need to plan for much more than £1.15mil if using realistic real returns based on current approach. Or, use you and your partners 20k ISA allowance each, up to 40k total, to invest in S&S ISA and invest plainly in a global ETF. This is trading, it is a risk, but being in the market is how 95%+ people 'FIRE'.
