Stevenswood - "Congratulations to SEP Windows, our latest Installer of the Month, supported by our Doncaster Trade Counter.

This beautiful cottage has been transformed with 14 REHAU Total70S astragal bar windows and a Door-Stop composite door, replacing the original timber windows while keeping the property's traditional charm.

A fantastic installation that delivers all the modern benefits of uPVC without losing the character
of the home.

Well done to the team at SEP Windows."

We currently have a limited number of Worcester Bosch 3200i and 7000i 2.6kW wall-mounted single split air conditioning units left in stock, the perfect solution for bedrooms, living rooms, home offices and other smaller spaces.

Installation prices start from just £1,600, and thanks to the Government's current VAT relief on qualifying energy-saving installations until March 2027, there's no VAT to pay, making now an excellent time to invest.

🔥 Demand has been exceptionally high, and these are some of the last Worcester Bosch units we currently have available. Once they're gone, stock will be extremely limited, so if you've been thinking about installing air conditioning, now is the perfect time to secure yours.
