COVID-19 Update 

We are still undertaking boiler installations and servicing, servicing is very important to maintain the boiler and to make sure it is safe, the Government and Gas Safe Register are keen for us to maintain essential services and try to avoid hazards due to unserviced and potentially dangerous appliances.

Servicing will be undertaken where safe distancing rules can be maintained, our engineer will use all necessary PPE and work to strict government guidelines. If you are experiencing symptoms of Covid-19 or shielding you MUST notify us before the visit.

All surfaces will be wiped with anti bacterial wipes after we are finished. We are relying on the customer playing their part in this to maintain our safety as well as yours. To make things easier for the engineer to avoid contact with you if you can leave a side door, garage door open or even a route to the boiler position (for undisturbed access) that would be great, please advise us at the time of booking. We can also arrange payment to be made via a Bacs transfer to avoid any unnecessary contact.

In these uncertain times can I take the opportunity to thank you for your business and continued support and we hope you are keeping well.

Take care and stay safe.  

Gareth Williams.
