Loft Insulation Eastleigh
Loft insulation for Eastleigh homeowners
At Loft Insulation Specialists, we help Eastleigh homeowners cut heating bills with loft insulation installed to 300mm of Knauf Earthwool or Superfoil. The oldest properties are the pre-1919 terraces in the town centre, solid-walled beneath a continuous pitched roof. Those lofts often contain minimal insulation, thinnest at the eaves. Boyatt Wood, Chandler’s Ford and Hiltingbury are post-war estates of semi-detached and detached properties. Each has an accessible pitched loft, and the mineral wool there has usually settled below 100mm.
Up to 35% of a home’s heat escapes through an uninsulated roof. A free, no-obligation survey measures what your loft holds now, and you receive a fixed-price quotation before you book any work.
How Eastleigh homeowners benefit from Loft Insulation
Every Eastleigh loft insulation survey settles the same three decisions: whether the existing insulation stays, which material we install, and what happens to anything stored up there. The existing insulation is the principal question on Eastleigh’s post-war estate properties at Boyatt Wood and Chandler’s Ford. Dry mineral wool below 100mm remains in position, and we install Knauf Earthwool over it to 300mm. The sections below explain each decision.
Keep the quilt that is there, or start again
Dry mineral wool insulation that lies flat and springs back when pressed stays in position, and we lay new Knauf Earthwool over it to reach 300mm. Damp, stained or compressed insulation comes out first, because fibres in that condition never recover their original thickness. The survey settles which applies to your property, and the quotation states it.
Knauf Earthwool or Superfoil
Knauf Earthwool is the standard material: mineral wool insulation laid between and then across the joists to a 300mm depth, with a 40+ year service life. Superfoil is the multifoil alternative for a property with shallow joists or a floor you want to keep usable, because it delivers the same thermal performance in around one-fifth of the thickness. Most properties take Earthwool, and the survey confirms which material suits yours.
Boxes, boards and the hatch
Boxes placed directly on the insulation compress it, and boards screwed directly onto the joists over 100mm of mineral wool compress it equally. We move stored items aside on the installation day, and where you want to keep the storage, raised loft boarding on stilted legs sits above the full 300mm of insulation. We insulate and draught-strip the hatch surround as part of every installation.
Common loft insulation issues in Eastleigh homes
In Eastleigh’s town centre, the pre-1919 terraces share one continuous pitched roof along each row and have solid walls. Each loft space is narrow between its party walls, and the insulation frequently terminates before the front and rear eaves. The post-war semi-detached and detached estate properties at Boyatt Wood, Chandler’s Ford and Hiltingbury have accessible pitched lofts. The mineral wool insulation in those properties has usually settled below 100mm, with the minimum depth at the eaves. We measure the depth between the joists and specify a top-up or a replacement installation in the quotation.

We photograph the condition of the loft and confirm whether a top-up or a complete replacement is the better value.

We calculate your fixed-price quotation from the loft floor area, the access and the survey findings, naming Knauf Earthwool or Superfoil as the material.
If you receive certain benefits and your EPC rating is D-G, we'll help you check ECO4 eligibility and carry out a funded installation under the scheme.
We set out labour, materials, disposal of any old insulation and the completion time in writing before you book the installation.

Professional Loft Insulation service provided
A standard Eastleigh loft installation takes 4–6 hours with a two-person crew, and we bring our own ladders and equipment.
We lay protective sheeting across the landing and staircase before the installation begins, and we contain the dust at the hatch opening.
Before we leave you inspect the finished depth with us, the eaves ventilation left clear and any old insulation bagged for licensed disposal.
How much does Loft Insulation cost in Eastleigh?
Loft insulation in Eastleigh costs between £600–£1,500 for a typical three-bedroom semi-detached home, or £15–£22 per square metre including materials and labour. Clearing old material with licensed disposal adds £650 where the survey identifies it.
A post-war semi-detached property at Boyatt Wood or Chandler’s Ford usually occupies the lower end of the range. A top-up over dry insulation through an unobstructed hatch is the standard installation there. A larger detached property at Hiltingbury, or a town-centre terrace with boarding to remove first, costs nearer the upper end. The survey measures the floor area and the hatch access, and the quotation prices the labour from both. We confirm the price after the survey, and we add nothing afterwards.

Frequently asked questions
Take a look at the Frequently Asked Questions regarding our Loft Insulation services in Eastleigh.
Can a grant pay for loft insulation in Eastleigh?
Possibly. ECO4 funding is still available but in its final stage, and the programme winds down completely on 31 December 2026. It applies if you receive certain benefits and your home’s EPC rating is D-G. The Eastleigh properties most likely to hold under 100mm of insulation are the pre-1919 terraces in the town centre. The post-war estate properties at Boyatt Wood are the second group, because their mineral wool insulation has settled since installation. We’ll help you check your eligibility at the survey and carry out a funded install under the scheme.
Which Eastleigh homes gain most from new loft insulation?
Eastleigh’s pre-1919 terraces benefit most from new loft insulation. Their solid walls have no cavity to fill, and their lofts often contain minimal insulation. Raising a loft from minimal insulation to 300mm of Knauf Earthwool makes the largest difference to a heating bill. The post-war semi-detached and detached properties at Boyatt Wood, Chandler’s Ford and Hiltingbury benefit nearly as much. Their mineral wool insulation has settled below 100mm, and a top-up installation over dry material costs towards the lower end of the range. We measure every property before the quotation specifies the material and the finished depth.
Do I need to empty my Eastleigh loft before you arrive?
No, not completely. We move boxes and furniture on the loft floor aside on the installation day, because the insulation runs across every joist bay. Anything on a raised boarded platform stays in position throughout the installation. Tell us at the survey what is stored up there, and the quotation allows for moving it.
What do you do with old loft insulation from Eastleigh homes?
We bag damp, stained or compressed insulation in the loft and transport it to a licensed disposal facility. We never reuse it, because wet mineral wool does not recover its thickness once dried. Dry insulation in good condition stays in position, and we install the new material over it. Removal adds 2–4 hours to the installation, and the quotation states it before the day.
How do I arrange a loft insulation survey in Eastleigh?
Request a quotation through the contact form or on 023 9326 7900, and we arrange a free, no-obligation survey the same week. The fixed-price quotation follows in writing. We cover Eastleigh and the surrounding area, and our Eastleigh service area page lists the neighbourhoods we cover for insulation work. A boarded floor covers the joists we measure between, and we allocate survey time for it if you mention it when booking.
