Common questions

What counts as an emergency callout?
No heating or hot water, a burst or leaking pipe, or a suspected gas issue. We're available round the clock and will tell you honestly how quickly we can get to you. Gas escapes should be reported to the National Gas Emergency line (0800 111 999) first.
My boiler has broken down — what should I do first?
Check the pressure gauge (should read between 1 and 1.5 bar) and try pressing the reset button. If it fires and cuts out again, or if you can smell gas, call us straight away. Don't open the boiler casing yourself.
How often should I service my boiler?
Once a year, ideally before winter. Annual servicing keeps your manufacturer's warranty valid, maintains efficiency, and catches small problems before they become expensive. We'll remind you when yours is due.
Do you work on all boiler brands?
Yes — Worcester Bosch, Vaillant, Baxi, Ideal, Viessmann and more. If a model is particularly old or obscure we'll flag any parts concerns before we start.
How much does a new boiler cost?
It depends on the boiler type, your existing setup and how straightforward the installation is. We'll give you a fixed, itemised quote before any work starts. Call or WhatsApp for a ballpark first.
Are you Gas Safe registered?
Yes. All gas work is carried out by Gas Safe registered engineers. We're happy to show our ID card before any job, and you can verify us on the Gas Safe Register website.
