Repair or Replace: The Honest Test
The first job on any hot water call is deciding whether to fix or replace. A repair is worth it when the tank still holds water and one part has failed.
Signs a repair will do:
- Water lukewarm or cold, but no leaks: likely the element or thermostat.
- A relief valve dripping or hissing: swap the valve, keep the unit.
- A gas unit that will not light or keeps losing its pilot.
- Hot water at every tap but one.
- A puddle around the base: the cylinder has rusted through, and no part fixes that.
- A major part failing on a unit that is already decades old.
- Rusty flecks coming out of the hot taps.
Once we know which list your unit is on, the price follows from that.
Which System Suits an Older Terrace?
Household size, the fuel already piped or wired in, and the spot a tank can squeeze into all steer the choice. We install and service all of these:
Electric storage
Instant electric
Gas storage
Continuous-flow gas
Heat pump
Solar
Our licensed gas fitters connect the gas units, and the gas fitting hub lists what else they fit.
What Shapes a Hot Water Quote?
We provide up-front, honest quotes that will always match the final price, should you decide to go ahead.
The unit you choose sets most of the figure. After that:
- Size A small tank for two people costs less than a big unit for a house full of share-mates.
- Getting it out A tank stuck down a narrow terrace side path takes longer to remove than one in an open laundry.
- The changeover New valves, a tempering valve, disconnecting the old tank and taking it away are all part of the price.
- Timing After-hours work costs more, and we give you that rate on the phone.

Jobs That Belong to Another Trade
When we're not the right call: if the power never reaches the tank, because an old fuse has blown or the circuit needs upgrading, that is work for a licensed electrician. We look after the water and gas side, explain what we found, and leave the wiring to the sparky.
What Customers Say
Karen's system gave out and the changeover still ran to plan:
They gave us a prompt quote with different options and helped us with a temporary hot water tank while the new system arrived and was installed.
Questions Cooks Hill Locals Ask About Hot Water
Do you fix hot water in rented flats?
Yes. The tenant rings us direct and explains the fault, and we price the fix. The owner or agent approves it and gets photos plus an itemised invoice once the tank is heating again.
Will we have hot water while the new system is on order?
Yes, where it can be arranged. Where the old tank cannot be saved, a temporary one can go in so you still get hot showers while you wait for the replacement. Ask about it when we quote.
Which system suits a small terrace?
Census figures put the average Cooks Hill household at two people, so a compact storage tank or an instantaneous unit covers the load. If running cost matters most, see the heat pump page for the lowest-energy electric choice.
Do you handle the gas side as well as the electric?
Yes. Licensed gas fitters on our team install and service gas tanks and instantaneous gas heaters, and can connect a cooktop in the same visit. The full list of gas work is on the gas fitting hub.
