A cylinder is a battery for hot water, and like any battery the questions are how big it needs to be, how it is charged, and how fast it goes flat.

Which you have decides what can go wrong and what replaces it.
An unvented cylinder needs its safety valves and discharge pipe right.
A cylinder that will not hold heat is diagnosed before it is replaced.
Straight swap or upgrade, each priced so you can choose.
A vented cylinder is fed by a cold tank in the loft and works on gravity, so its pressure is whatever the height difference gives you, which is usually modest. It is simple, tolerant and cheap to maintain.
An unvented cylinder is fed straight off the mains, so every outlet in the house runs at mains pressure, which is why showers from an unvented feel like showers. The trade is that it is a sealed pressure vessel, and that brings requirements: an expansion vessel, a temperature and pressure relief valve, and a tundish and discharge pipe that can take boiling water safely to outside without scalding anybody or running uphill. In a flat or a basement, finding that discharge route is frequently the hardest part of the whole installation.
Hot Water Cylinder is priced after the job has been seen, anywhere in the areas we cover. Send the postcode and a few lines about what it is doing when you contact us, and the answer comes back in writing.
Bathrooms, not bedrooms. A single bathroom household is comfortable on a smaller cylinder; two bathrooms likely to be used in the same half hour need meaningfully more stored volume, and a bath filled while someone showers is the demand that catches people out. The reheat time matters as much as the volume: a large cylinder on a small boiler output recovers slowly, so the two get sized together.
Usually one of three things, and they are distinguishable. A failed immersion thermostat or a boiler coil that has scaled, so it never reaches temperature in the first place. Insulation that has degraded, or a modern cylinder losing heat through poorly lagged tails at the top, which is the commonest and cheapest to put right. Or gravity circulation, where hot water rises out of the cylinder into uninsulated pipework and cold returns, quietly draining the store overnight. The third one is why the pipes above a cylinder are warm in the morning when nothing has run.
The expansion vessel loses its charge, and when it does the relief valve starts discharging and you get water from the tundish for no apparent reason. The vessel charge and the relief valves are checked annually, and that is not optional maintenance, it is what keeps a pressure vessel behaving like one.
Whether it is leaking, not heating or running out, and a photo of the cylinder and its label. That tells us vented or unvented straight away.
