Loft Insulation Gosport
Loft insulation for Gosport homeowners
At Loft Insulation Specialists, we help Gosport homeowners cut heating bills with loft insulation installed to 300mm of Knauf Earthwool or Superfoil. Gosport’s housing comprises the pre-1919 terraces around Newtown, the 1930s semi-detached houses at Elson and Hardway and the post-war estates at Bridgemary and Rowner. The 1930s and post-war houses have cavity walls and larger, more accessible pitched-roof voids. The Newtown terraces and the Georgian and Regency villas at Alverstoke have solid walls, and cavity-wall insulation does not apply to them.
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 Gosport homeowners benefit from Loft Insulation
Every Gosport 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. On the 1930s semi-detached houses at Elson and Hardway the keep-or-replace decision takes precedence. Their large pitched voids usually hold a single layer of mineral wool, which we measure against the 100mm threshold. 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 Gosport homes
Flats and maisonettes constitute a substantial proportion of Gosport’s stock, from the 1950s-60s high-rise blocks to the naval estate at Rowner. Most have no individual accessible loft, and we survey the roof void before preparing a quotation. Any surviving prefabricated house at Bridgemary or Rowner has non-standard roof construction. The survey records the roof form before we specify a material. The 1930s semi-detached houses at Elson and Hardway have larger pitched-roof voids with capacity for 300mm of Knauf Earthwool across the joists. The pre-1919 terraces around Newtown have small pitched roofs over narrow plots, and the constrained loft access restricts the batts we pass through the hatch.

- 1
Book your free Gosport survey
Book a free, no-obligation survey and we visit your Gosport property the same week to measure the existing insulation.
We measure the insulation depth between the joists, press the material for compression and check the eaves ventilation for airflow and staining.
We photograph the condition of the loft and confirm whether a top-up or a complete replacement is the better value.
- 2
Receive your fixed price quote
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 Gosport 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 Gosport?
Loft insulation in Gosport 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.
Where the existing insulation is dry and the hatch is unobstructed, a 1930s semi-detached house at Elson or Hardway usually occupies the lower end. A Georgian or Victorian villa at Alverstoke or Lee-on-the-Solent has a larger loft floor area to insulate. A Newtown terrace with constrained access and boarding to lift requires additional labour. Both cost nearer the upper end. 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 Gosport.
Can a grant pay for loft insulation in Gosport?
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. Under 100mm is the usual measurement in Gosport’s 1930s semi-detached houses at Elson and Hardway and its post-war council houses at Bridgemary and Rowner. Both have large pitched voids containing a single compressed layer of mineral wool. We’ll help you check your eligibility at the survey and carry out a funded install under the scheme.
Which Gosport homes gain most from new loft insulation?
Gosport’s post-war council houses at Bridgemary and Rowner and its 1930s semi-detached houses at Elson and Hardway gain most from new loft insulation. Their large pitched voids usually hold a single compressed layer. The reduction in the heating bill from 300mm of Knauf Earthwool is greatest where the existing depth is lowest. The pre-1919 terraces around Newtown and the Georgian and Regency villas at Alverstoke gain nearly as much. Their solid walls accept no cavity fill, which leaves the loft as the first available measure. Our survey records what each loft holds, and the quotation sets out the finished specification.
Do I need to empty my Gosport 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 Gosport 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 Gosport?
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 Gosport and the surrounding area, and our Gosport service area page lists the neighbourhoods we cover for insulation work. Tell us when you book if your property is a Newtown terrace or a Rowner maisonette. We allocate additional survey time for a constrained hatch or a shared roof void.
