Water under the boiler in a tenement flat is a neighbour problem as well as yours. Turn the boiler off, close the isolation valves if you can reach them, and call us — same-day attendance before 2pm.
Leaking boiler in Edinburgh — urgent repair?
A leaking boiler is usually a failed pump head gasket, a corroded heat exchanger, a weeping pressure-relief valve or a loose compression joint on the pipework beneath the casing. In Edinburgh flats it should be treated as urgent because of the damage risk to the property below. Turn the boiler off at the fused spur and call 0800 193 1505.
Key points
Pump head gasket perished
Pressure-relief valve passing because system pressure is too high
Corroded primary heat exchanger — usually terminal on older units
Loose or work-hardened compression joint under the casing

Water and electricity together are, and a leak onto the PCB can cause a short. Turn the boiler off at the spur. If you can also smell gas, leave the property and call the National Gas Emergency line on 0800 111 999 first.
Who pays if it damages the flat below?
Your buildings and contents insurer usually deals with escape-of-water claims, but acting fast and getting a written engineer's report — which we provide on every visit — makes the claim far simpler.
How much does a boiler repair cost in Edinburgh?
Heatscape charges a fixed £95 diagnostic across every EH postcode, deducted in full from any repair carried out on the same visit. Out of hours (after 6pm and weekends) is £140. Most common repairs land between £120 and £420 all-in including parts and labour. If a repair would cost more than about £600 on a boiler over 10 years old, we quote a like-for-like replacement at £2,295 instead.
Are boiler repairs guaranteed?
Every repair carries a 12-month workmanship guarantee, and manufacturer part warranties are passed through in full. If the same fault returns inside 12 months there is no second diagnostic fee.

Tenement flue routing was a nightmare with the last quote we got. Heatscape actually solved it and dealt with the factor for us. Damp gone too.
