Summary:

G-IFLP encountered control difficulties due to airframe icing resulting in a descent below the cleared level. The pilot requested clearance to descend but was not able to convey the seriousness of the request whilst also manually flying the aircraft and operating the de-icing system. The controller did not detect the urgency of the situation and instructed the aircraft to maintain altitude. This resulted in a brief loss of separation with another aircraft.
