What does a hot tub repair cover?
A hot tub repair is a visit to find and fix a fault, such as a leak, no heat, a pump that will not run or a tripping supply. The engineer works out the cause, then quotes for parts and labour before fixing it.
A repair can involve any of these parts:
- The heater and its sensors
- Circulation and jet pumps
- Jets and diverter valves
- The control pack and topside panel (Balboa, Gecko and others)
- The flow or pressure switch
- Unions and pipe joints
- Airlocks and frozen pipes
Repair or service?
A service is a routine yearly check that keeps a working tub in good shape. A repair fixes something that has gone wrong. If your tub works but hasn’t been looked at for a while, book an annual hot tub service instead. If a repair would cost more than the tub is worth, see hot tub removal.
How does our hot tub repair service work?
1. Tell us the fault.
Say what’s happening, note any code on the panel, and add a photo if you can.
2. We match you.
We pass your request to up to 2 local engineers who cover your postcode.
3. Compare and book.
Each engineer quotes you directly. You choose, and you book with them.
We cover swim spas too, so ask for a spa repair in the same way. Read more about how our matching works.
What a hot tub engineer checks
A good engineer checks the power, water level, filter and flow first. Then they test the heater, pumps, sensors and control pack, and look for leaks in the equipment bay. Once they find the cause, they explain it and quote for the fix.
What are the most common hot tub faults?
Here’s what each fault can mean, one safe check, and when to call an engineer.
Hot tub not heating
The pumps run but the water stays cold. Common causes are a dirty filter, low flow, a faulty flow switch, a failed heater element or the wrong settings. Check the filter and the set temperature. If it still won’t warm up, an engineer can test the heater.
Hot tub leaking or losing water
Water under the cabinet usually comes from a loose union, a worn pump seal, a jet or a pipe joint. Look for wet patches around the equipment bay, with the power off. Hot tub leak repair needs an engineer to find the exact spot.
Hot tub tripping the electrics
Water in the equipment bay or a failing heater element can trip the RCD. Reset it once only. If it trips again, leave it off and call for help (Canadian Spa Company).
Pump not working or humming
A pump that hums but won’t spin may have an airlock, or the engineer may find a motor or capacitor fault. Check the water is above the skimmer. Leave the rest to a professional.
Jets not working or weak
Weak jets often mean closed jets, a diverter in the wrong place, a blocked filter or an airlock. Open each jet and clean the filter. If the flow stays weak, the pump may need checking.
Control panel blank or no power
A blank topside panel can mean a tripped supply, a loose connection or a control pack fault. Check the isolator by looking only. Never open the control box yourself.
How much do hot tub repairs cost?
Public price lists put a hot tub call-out at about £80 to £265, usually with the first hour or half hour included. Parts and extra time cost more. Leak work costs more again. These are estimates from public price lists, not our prices. Checked October 2026.

|---|---|---|---|---|---|
| Extreme Hot Tubs | Kent, Herts, Essex, Surrey | £80 | 1 hour on site | £40 per half hour | Extreme Hot Tubs |

| Leak repair | As above | From £249 minimum (Dr Hot Tub); leak detection £350 to £550 inc VAT (Revive Pools) | Varies | Varies | Dr Hot Tub; Revive Pools |
These are estimates from public price lists, not our prices. Checked October 2026.
What affects the price
The fault itself, and whether parts are needed. How easy it is to reach the equipment bay. How far the engineer travels. Whether VAT is included.
What do hot tub fault codes mean?
On Balboa controls, “FLO” means improper flow or a pressure switch fault (H2O). Most codes point to water flow, water level or temperature. Codes differ by brand, so Gecko and others use their own. Check your manual first, then use the table below as a guide.
| Code | What it means | Safe first step | Call an engineer when |
|---|---|---|---|
| FLO | Improper flow or a pressure switch fault | Clean the filter and check the water level | The code comes back |
| dr / DY | Possible low water, poor flow or air in the heater. The spa stops for 15 minutes. On the third time it shows DY and needs a manual reset | Top up the water and open the jets | It shows DY again after a reset |
| OH | Water reached 43°C (110°F) | Don't get in. Let it cool | It happens again |
| OHH | Heater reached 47.8°C (118°F) | Don't get in. Let it cool | Straight away |
| LF | Low flow 5 times in one day. The heater is disabled | Clean the filter and check for airlocks | Straight away |

What should you check before calling an engineer?
A few safe checks can save a wasted visit:
- Clean or rinse the filter
- Check the water is at the right level
- Make sure the jets are open
- Look at the isolator to see if it’s on (look only)
- Write down any code on the panel
Safety first. Reset a tripped RCD once only. If it trips again, leave it off. Never open the control box, and never run a hot tub from an extension lead (Canadian Spa Company).
Electrician or hot tub engineer?
Call an electrician for the supply, RCD, isolator and cable. Call a hot tub engineer for the heater, pumps, control pack and sensors. Some faults need both (H2O Hot Tubs). The IET notes that wet skin and bare feet raise the shock risk outdoors (IET).
What to tell the engineer
Give the make and model, any code, a photo of the panel and equipment bay, and when the fault happens.
Should you repair or replace your hot tub?
Most faults are worth fixing. Mend or End says UK repairs typically cost £100 to £500, while new tubs start from about £2,000 (Mend or End). These are estimates, checked October 2026.
Think about replacing when the shell is cracked, big faults keep coming back, or parts are no longer made. Bought a house with an old tub that won’t start? Ask an engineer to look before you decide. A single hot tub repair is often far cheaper than a new tub.
How do you choose a hot tub engineer?
Ask each engineer about:
- Their public liability insurance
- Experience with your make and controls
- A written quote with clear call-out terms
- A guarantee on parts and workmanship (UK Hot Tubs, for example, offers 1 year: UK Hot Tubs)
- How they handle leaks they can’t find on the first visit
- References you can check
Holiday lets
If you run a holiday let, tell us in your request so engineers know guests are due. Getting two quotes at once saves you ringing round.
How we vet engineers
Before a technician gets any requests, we check they have public liability insurance of at least £1 million. We also check for an active Companies House record, or at least 5 genuine reviews on Google or Checkatrade. We don’t carry out DBS or criminal record checks, so please make your own checks too.

Is it worth repairing a hot tub?
Usually, yes. Mend or End says UK repairs typically cost £100 to £500, while a new tub starts from about £2,000. Unless the shell is cracked, repairing is often the cheaper choice. Estimates, checked October 2026.
Is it worth fixing a 10 year old hot tub?
Often, yes, if the shell and frame are sound and parts are still made. Age alone doesn’t decide it. An engineer can check the shell and control pack. If big faults keep coming back, compare the quote with a new tub.
How much does a hot tub engineer cost?
Public price lists put a call-out at about £80 to £265. Extreme Hot Tubs charges £80 and Dr Hot Tub £90 for a diagnostic visit. Parts are extra. Estimates, not our prices. Checked October 2026.
What is the most common leak in a hot tub?
Leaks most often come from loose pipe unions, worn pump seals and jets. An engineer needs to find the exact spot. Dr Hot Tub lists a £249 minimum for leak repairs (estimate, checked October 2026).
Why is my hot tub losing water overnight?
Some loss from splashing and heat is normal. If the level drops a lot, or the ground under the tub is wet, it’s likely a leak. Check the cabinet for damp with the power off, then ask an engineer to find it.
Why is my hot tub running but not heating?
It’s usually a flow problem or a heater fault. A dirty filter, low water or an airlock can stop the heater. So can a faulty sensor or element. Clean the filter and check the set temperature. If it stays cold, call an engineer.
Why does my hot tub keep tripping after a reset?
Often water near the electrics or a failing heater element is to blame. Reset the RCD once only. If it trips again, leave it off. An electrician handles the supply and cable; a hot tub engineer handles the heater, pumps and control pack.
Do hot tub leak sealers work?
They may slow a very small leak for a while. They won’t fix a split union or worn pump seal, and they can hide where the water is escaping. For a lasting fix, ask an engineer to find and repair the leak.
Does my hot tub need a repair or just a service?
If something has stopped working or a code keeps showing, you need a repair. If the tub works well but hasn’t been checked for a year or more, book an annual hot tub service instead.
