Frequently Asked Questions
Will a new smart thermostat work with my existing boiler?
Most modern boilers and systems are compatible with smart thermostats, but some older or oil-fired appliances may need an additional relay or interface. Our Gas Safe and OFTEC engineers carry out a free compatibility check during the survey and explain any extra parts required.
Do you offer room zoning and multiple thermostat installation?
Yes. We design zoning solutions for houses with uneven heat distribution, using separate thermostats or smart radiator valves to control temperatures per room. Zoning reduces waste and improves comfort in larger properties.
How long does a typical installation take?
A straightforward thermostat swap is usually completed in a morning or afternoon. More complex smart systems, additional wiring or multiple zones can take a full day. We give a clear timescale after the survey so you know what to expect on-site.
Will you show me how to use the new controls?
Yes. Every install includes a full on-site demonstration in plain English, written notes for reference and follow-up via WhatsApp for any questions after we leave. We make sure you know how to change schedules, boost heat and use eco settings.
Do you offer emergency support if controls stop working?
We provide emergency same-day response for urgent heating or hot water failures. If a control fault causes loss of heating, call or WhatsApp us and we will prioritise repairs to restore service quickly.
