OK, so, here are some ideas:
Washing: Get a machine which can take a big load and has a timer. Then, every night, you can programme it to come on in the wee hours, ready for you/DH to peg it out when you get up. Help yourself with this by having towels, bedding etc either all white or all colours. Store bedding in a box under each bed, with whole sets together, so you've always got it there ready. Get rid of all the extraneous bedding/clothes which get in the way and stop all this being easy.
Ironing: Do you really need to do this? (I don't.) If you do, cut it down to the minimum and ask your cleaner to do it.
Clothes: Declutter. Look into capsule wardrobes to simplify all decision making. When you find a classic item which you love, buy a few of them.
Shopping: Order groceries online for delivery. Diarise to do this.
Food: Plan meals, eg. a 2 week rotation. Look into batch cooking and slow cookers.
Working hours: (I mean this genuinely as I have done this myself.) Look at your spending and look at your hours. Does it add up? What I mean is, spending less means you don't have to work so much.
Diarising: Put in everything. Eg. Boiler service - I know my plumber is in demand, so I put it in to book it a month before I need it done. Similarly, if you speak to someone, always record their name, number and brief details.
Birthdays: Sit down every January, go through your birthdays for the year and buy all the cards. When they arrive, write and address them all and store them in date order. Set yourself auto-reminders so you know when to send them.
Declutter & stop letting more stuff come in: I can't tell you how much this has helped me. It makes everything easier.
