It is as easy as that!

To receive a £50 voucher of your choice, you simply must give your friend this discount code TBMES21 to use when booking their new boiler installation and we’ll send you your voucher when your friend’s boiler gets installed, they will get £50.00 off their new boiler or get a voucher.
