Not normally. Our guide prices include normal travel to Harpenden. If an address needs a ferry or an unusually long journey, we tell you the cost before you book.

How do I pay for work in Harpenden?

Should I insulate under the water tank in the loft?
No. Leave the ceiling directly under the tank uninsulated so a little warmth from the house reaches it. Insulate the top and sides instead.
Do I need a lid on my cold water tank?
Yes. A close-fitting lid keeps debris and insects out and is part of the water regulations for cold water storage.
