I strongly advise avoiding London Appliances. Their workmen caused a severe leak while working in the flat above mine, resulting in water pouring through my ceiling and fusing my kitchen electrics.
While mistakes happen, their handling of the aftermath has been unbelievably bad. It took 6 months of chasing and a threat of legal action for them to finally admit liability and agree to cover the repair costs and then they stalled payment for over 6 weeks leaving me out of pocket for the repairs I had paid for.
