Based on an average 3 bed house of 70m2 with a medium range carpet, underlay and fitting then approx. £3000 there is a calculator at Cavendish deVere where you can use to estimate floor costs and fittings

My stairs and a large bedroom cost about £1.2k (John Lewis). That as a pretty low range carpet but it's kept up really well x 

Westminster carpets, lordship Lane. Best selection, price and customer service. Theyre also extremely speedy at fitting! Can't recommend them enough, used them for over 20 years, used to have a base in balham.

Highly recommend Marc Charles Caroets - https://www.instagram.com/marccharlesca ... hubzZ2b2d0

We have a typical 4-double bedroom house BTC and I am wondering if anyone can let me know a ball park on getting the hall, stairs, landing and 3 bedrooms carpeted? Appreciate that it will be a ball park. If you have recommendations of best places to go for quality and value for money I would be very grateful.
