FREE Boiler service with the Gas Boiler Service Plan through HomeServe

Having a reliable boiler to bring heating and hot water to your home is a daily essential. But just like a typical car service, you need to get it checked regularly to make sure it's working properly. That's why Tonik have teamed up with HomeServe, one of the UK's leading home assistance providers, to offer a Gas Boiler Service plan through HomeServe completely FREE in the first year (usually £84) for renewing customers. A HomeServe approved Gas safe® registered engineer will conduct a service on your boiler free of charge. They will also offer advice and tips on using your heating more efficiently. Having your boiler serviced regularly may reduce the risk of a breakdown and may also help to prolong its life.

Please note:

Owing to the Covid-19 pandemic HomeServe need to prioritise emergencies and put their most vulnerable customers first, but don't worry your first Gas Boiler Service will still take place after 6 months of your plan start date.
