Service overview

Complete Smart Thermostat & Controls Services

We fit and maintain controls for boilers, heating zones and compatible hot-water systems. This includes smart thermostats, wired and wireless room thermostats, programmers, receivers, gateways, relays and smart radiator valves. We commonly find that control problems come from the receiver, wiring centre or setup rather than the thermostat itself. We therefore check the full control path before recommending replacement. Where compatible equipment supports load or weather compensation, we can also explain how those functions adjust boiler output.

Smart controls help when you want clearer schedules, remote access or separate temperature control in different rooms. They can also resolve awkward arrangements in Edinburgh tenements where the best thermostat position has no existing hallway wiring. Call us if your heating starts at the wrong time, the thermostat loses connection or the boiler fails to respond to a temperature change. We assess compatibility before fitting controls to a gas boiler.

New controls work best with an efficient heat source, so we can pair them with a boiler replacement where the old boiler is near the end of its life.

What we cover

What Smart Thermostat & Controls Covers

  1. Smart Thermostat Installation

    We install compatible smart thermostats with an app, receiver, hub or gateway where required. We connect the equipment, configure the heating schedule and show you how to change temperatures without relying on the app for every adjustment.

  2. Programmable Thermostats

    A programmable thermostat combines temperature control with timed heating periods. We set practical weekday and weekend schedules, check the temperature reading and explain temporary overrides, holiday settings and frost protection functions.

  3. Wired and Wireless Room Thermostats

    We replace wired room thermostats where suitable cabling already reaches the correct position. Where running a new cable would cause unnecessary disruption, we can assess a wireless room thermostat and position it away from draughts, direct sunlight and heat sources.

  4. Smart TRVs and Room Control

    Smart radiator valves can give individual rooms their own temperature schedules. We check whether the chosen valves work as stand-alone controls or communicate with the main thermostat, as this affects how they request heat from the boiler.

  5. Multi-Zone Heating Controls

    We configure multi-zone controls for properties with separate heating circuits. This may involve thermostats, zone controllers, motorised valve connections and a wiring centre. We test each zone independently so one control does not operate the wrong area.

  6. Programmers, Receivers and Control Modules

    We replace heating programmers, dual-channel controllers, thermostat receivers, boiler control relays and compatible hot-water control modules. We identify each connection before changing equipment and retain separate heating and hot-water schedules where the existing system requires them.

Before you decide

Common Heating Control Problems We Solve

  • My Smart Thermostat Will Not Connect

    We check the thermostat, receiver, hub and app connection separately. A failed internet connection does not always mean the heating control has failed. We commonly find pairing has been lost after a router change, power interruption or reset. We reconnect compatible equipment and confirm whether local thermostat control still works.

  • The Thermostat Is Not Controlling the Boiler

    We test whether the thermostat sends a demand for heat and whether the receiver or relay passes that demand to the boiler. A click from the receiver does not prove that the complete control circuit works. We check settings, wiring and communication before advising on a replacement part.

  • The Heating Comes On at the Wrong Times

    We review programmed periods, target temperatures, manual overrides and app schedules. Smart controls may hold a previous override or follow a different schedule from the one displayed on the wall unit. We reset the schedule where needed and test an actual on and off command with you.

  • I Need to Replace an Old Thermostat or Programmer

    We identify what the existing control operates before removing it. Older programmers may control both heating and hot water, while a room thermostat may use wiring that a new smart receiver can reuse. We compare suitable wired and wireless options and explain any change in day-to-day operation.

Customer reviews

Trusted in Edinburgh. Their Words.

  • The new kitchen mixer tap fitted to my sister's kitchen sink is excellent. It is much easier for her to use than the old one…

    Tony Rae, Edinburgh
  • Replaced a broken kitchen tap quickly and efficiently. Came the same day I phoned to look at the job. We got a written quote the next morning and it was fitted that afternoon.

    Fiona Steven, Edinburgh
  • Haggart Plumbers arrived at my home at the scheduled time. They were friendly, polite and solved my boiler problem in a matter of minutes. Based on this and previous experiences with them I do not hesitate to recommend them.

Our process

How We Handle Your Smart Thermostat & Controls

  • 1. Discuss How You Use the Heating

    We start with the rooms, schedules and controls you want to change. We ask whether you need app access, room-by-room temperatures, hot-water timing or straightforward wall controls. You have one point of contact while we plan and complete the work.

  • 2. Survey the Existing Setup

    We inspect the thermostat position, programmer, receiver, boiler connections and accessible wiring. In Edinburgh tenement flats, we often assess wireless controls where there is no suitable thermostat cable in the hallway. We also check broadband and hub positioning if the selected system requires an internet connection.

  • 3. Plan and Fit the Controls

    We confirm product compatibility and agree the control arrangement before fitting begins. We mount the thermostat, install the receiver or gateway, make the required control connections and configure any zones or smart radiator valves included in the job.

  • 4. Test and Explain Every Function

    We test heating demand, schedules, temperature changes, manual overrides and connected zones. Where the controls include app access, we help with pairing and basic setup. We then show you how to make everyday changes and explain which functions continue to work if the internet goes offline.

Common questions

Smart Thermostat & Controls Questions

We quote each job individually because the cost depends on the chosen controls, boiler compatibility, wiring and the number of zones or smart valves. A direct thermostat swap differs from a system requiring a receiver, gateway or wiring changes. We confirm the scope and quote before work starts.

We can fit smart controls to many existing boilers, but we check the make, model and current control connections first. Some boilers use basic on and off switching, while others support modulating communication. We recommend a control that matches the available functions.

We usually base the choice on wiring, thermostat position, internet access and the heating equipment rather than the building type alone. Wireless controls can suit Edinburgh tenements where no useful thermostat cable reaches the preferred location. We still check signal range and receiver position before fitting.

Yes, a wireless room thermostat may avoid running a new cable to the hallway. We assess where the receiver can connect and choose a thermostat position that gives a representative room temperature. Thick walls and property layout can affect the final position.

The time depends on whether we are completing a straightforward replacement or adding receivers, control modules, zones or smart radiator valves. We confirm the likely duration after checking the existing setup. Our contact hours are 7am to 7pm, seven days a week.

We check power, pairing, hub status, wireless signal and router changes before recommending replacement. We also test whether the thermostat can still control the heating locally. If a proprietary app or cloud service causes the fault, we explain what we can resolve on site.

Not always. Some smart valves only regulate individual radiators, while compatible systems can use them to request heat through a central hub. We check how the selected valves communicate with the main control so rooms do not call for heat without the boiler responding.

Yes. We can discuss straightforward controls for tenants, restricted settings and app access for the appropriate user. We usually recommend an arrangement that still allows clear control at the property, rather than making normal heating operation depend entirely on a phone.
