What does a full boiler service include?
A full boiler service typically includes a thorough inspection of the boiler and its components, cleaning of the boiler, testing of safety devices, and a check of the gas pressure and flue.
Do I need an OLEV-approved installer to fit my home EV charger?
To qualify for government incentives like the Electric Vehicle Homecharge Scheme (EVHS), your EV charger must be installed by an OLEV-approved (Office for Zero Emission Vehicles) installer. These installers have met specific standards and are authorised to install EV charging points under UK government programs.
How can taking shorter showers help me be more eco-friendly and economical?

What if my gas safety certificate has expired?

Do I need a Gas Safety Certificate to sell my house?
