We had a Tom Howley kitchen 8 years ago for a 5m x 3.5m kitchen. Didn't include range cooker or fridge which we already had, or flooring. Granite worktop and large island - came in at £40k.
The kitchen was beautiful, but they were a nightmare to deal with:
cancelled our installation date a week before it was due to start and told us the next one would be in 6 weeks (already 2 months without a proper kitchen),
fitted racks in drawers that weren't what had been agreed and tried to get out of changing them,
did most of the job and then left without telling us when they would be back and we had a nightmare getting them to come and finish the job,
under-cabinet light fittings used were impossible to change the bulb in,
they broke one of the shades on the main light fitting and refused to replace it.
Like I said, beautiful kitchen but overpriced and I really wouldn't recommend them.
