Boiler Installations
We specialise in installing modern condensing boilers that improve efficiency to over 90%, potentially saving 30% annually on heating bills. Our Worcester Bosch-accredited team provides full surveys and installations for regular, combi, or system boilers. With up to 12-year manufacturer warranties available when combined with system filters, our installations ensure long-term reliability and energy savings for residential and commercial properties.
Heat Care Plans
Our comprehensive care plans offer protection against unexpected breakdowns with tiered coverage options. Bronze, Silver, and Gold plans cover parts, labour, and unlimited callouts with annual fees from 135. Silver and Gold plans include annual boiler servicing, while Gold extends coverage to radiators and pipework. These plans help maintain warranty validity through required annual maintenance by qualified engineers.
Gas Safety Certificates
We provide essential Gas Safety Certificates for landlords and homeowners through thorough inspections of gas appliances and systems. Our Gas Safe-registered engineers identify potential hazards like carbon monoxide leaks while ensuring compliance with safety regulations. These certificates are crucial for rental properties and recommended annually for all gas heating systems to maintain safety and efficiency.
Boiler Servicing
Annual boiler servicing maintains optimal performance and warranty validity through comprehensive checks and adjustments. Our engineers inspect components, test efficiency, and identify potential issues before they cause breakdowns. This preventative maintenance extends boiler lifespan while ensuring safe operation. Servicing is included in Silver and Gold care plans at competitive rates from 89.50 per year.

We install Megaflo unvented hot water systems that deliver high-pressure performance throughout properties of all sizes. These energy-efficient systems eliminate loft cisterns for quieter operation while providing instant hot water access. Available in various capacities, they suit everything from studio flats to large mansions.

Report
Telephoned three various plumbing companies at six in the evening and left messages. I had an emergency, water coming through the bathroom ceiling. All three companies were advertising a 24 hr service. Two contacted me that evening and a company came at 6.30am the following morning, the leak was dealt with, the ceiling is drying out. However KTH Services did not respond for two days via a text. Why advertise a 24hr service when you don't provide one? KTH came recommended but I won't be using them in the future.
