Multi-split air conditioning in Southend-on-Sea
Long sunny spells in the East of England put conservatories and top-floor rooms under real pressure. In a house in Southend-on-Sea with a usable loft, multi-split pipes can often run through it so the front stays clear.
Multi-split is a good fit for Southend-on-Sea flats and maisonettes where only a balcony or one rear wall is available. We cover Southend-on-Sea and the rest of Essex, including Basildon and Colchester. Postcode districts we cover here include SS1 and SS22.
Prices in Southend-on-Sea

That is above the UK middle, mainly because labour and access cost more in the East of England. The biggest variables are the pipe route, access for the outdoor unit and the state of the consumer unit, all of which the survey settles.
