Traditional Boiler with Hot Water Tank - Can I plumb a shower?

If installing a pump you need to consider the size of the cws tank, ideally min 25gallon. As it will be feeding h &c supplies

Yeh I know what you mean. Unfortunately the bath needs replaced and wallboards will be mounted at the same time. Plus the current electric shower is 18 years old and is no longer white and has went yellow.

You can get a thermostatic bath/shower mixer which would give you the benefits of anti-scald for your bath water & save you plumbing & chasing in a separate shower mixer.

You can get pumped showers that use the feeds from vented HW and CW tanks e.g. https://www.screwfix.com/p/mira-go-rear-fed-white-chrome-power-shower/25745

Trouble you may have is pressure imbalance from cold (if mains fed) and the vented HW.

Expensive alternative is changing the HW tank for an unvented tank (so mains water pressure for both H and C).  That's the rolls royce solution though (and can lose the CW loft tank).

Examine the payback times based on your shower use and kWh costs of heating the HW.

NB Unvented tank and power shower pumps may result in more water use than an electric shower.  Factor that in the cost/payback also.

Thanks!! It would be great to remove the cold water tank in loft. Would an unvented tank work on a heat pump boiler system (if i get heat pump in a few years time)?

Yes you can get a heat pump ready cylinder and it will still work with a gas boiler- and be slightly more efficient potentially. They are a few hundred pounds more to buy.

We’ve just done this and put the cylinder in the loft where the large cold water tank was. Much Quieter as well as the significant improvements in water pressure.
