Try one at home
Three short jobs from our courses, written the way we teach them in our live online classes. Open the steps to follow along.
Lesson 1 · 20 min
Solder a 15mm end-feed joint
Kit: pipe cutter, deburrer, wire wool, flux, solder, blowtorch, heat mat
Show steps
- Cut the pipe square and deburr inside and out.
- Clean the pipe end and fitting until bright.
- Apply a thin coat of flux and push fully home.
- Heat the fitting, not the solder, until flux sizzles.
- Feed solder until a full ring shows at the mouth.
- Leave to cool, then wipe off flux residue.
Always use a heat mat and keep a damp cloth and extinguisher nearby.
Lesson 2 · 30 min
Bleed and balance radiators
Kit: radiator key, cloth, lockshield key, thermometer
Show steps
- Turn the heating off and let radiators cool.
- Open each bleed valve a quarter turn until water spits.
- Check boiler pressure; top up to about 1–1.5 bar cold.
- Open all lockshields fully, then run the heating.
- Close the nearest radiator’s lockshield to slow it down.
- Aim for roughly a 10–12°C drop from flow to return.
Hot water and steam can scald. Only bleed radiators when cool.
Lesson 3 · 25 min
Fit a basin isolation valve
Kit: 15mm isolating valve, spanners, PTFE tape, bucket
Show steps
- Turn off the water at the stopcock and drain the tap.
- Cut the supply pipe below the tap connector.

- Seat the valve, hand-tighten, then a turn with spanners.

If you cannot find or close your stopcock, stop and call a plumber.

Questions
Before you book
Do I need any experience?
No. The Foundations and DIY courses start from zero. Intermediate courses assume you can already make a sound joint.
Do I need my own tools?
Not to watch and learn. If you want to practise along, we email a tool and materials list before the course starts.
Will this make me Gas Safe registered?
No. Gas Safe registration needs a separate assessed qualification. Our heating courses cover the water side of systems and prepare you for that route.
Can my company book a private course?
Yes. We run courses for teams of up to six on dates that suit you.
I live outside the UK. Can I still train with you?
Yes. All our courses are online, so you can join from any country. You can pay in GBP or USD.
Where do you install and clean air conditioning?
Anywhere in Great Britain: England, Scotland and Wales. We do not carry out installations outside Great Britain.
How often should air con be cleaned?
Once a year for most homes. Twice a year for busy offices, kitchens or dusty sites.
