Loft Insulation Basingstoke
Loft insulation for Basingstoke homeowners
At Loft Insulation Specialists, we help Basingstoke homeowners cut heating bills with loft insulation installed to 300mm of Knauf Earthwool or Superfoil. More than a third of the town’s homes are semi-detached and detached properties on the 1960s-80s estates. Most have a conventional pitched loft, accessible through a landing hatch, where the original mineral wool insulation has settled below 100mm. The extended post-war semis commonly have insulation terminating at the original rear wall. The pre-1919 terraces in the town centre have solid walls, which makes loft insulation the principal thermal improvement available.
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 Basingstoke homeowners benefit from Loft Insulation
Every Basingstoke 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 1960s-80s estate properties the first decision matters most. The insulation installed at construction has usually settled below 100mm and, where it remains dry, stays beneath the additional Knauf Earthwool. 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 Basingstoke homes
The largest group of Basingstoke lofts belongs to the 1960s-80s estate properties at Winklebury, Oakridge, South Ham and Brighton Hill. Their original mineral wool insulation has settled below 100mm, thinnest at the eaves. In extended post-war semi-detached houses the insulation terminates at the original rear wall, and the extension roof beyond it frequently has no insulation. The pre-1919 terraces in the town centre have small hatch openings that restrict the material we can pass through. Their insulation often sits beneath boarding fixed directly to the joists. Properties from the 2000s at Hatch Warren and Beggarwood meet a later insulation specification and usually require only a top-up installation.

- 1
Book your free Basingstoke survey
Book a free, no-obligation survey and we visit your Basingstoke 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.

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 Basingstoke 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 Basingstoke?
Loft insulation in Basingstoke 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 three-bedroom estate semi-detached house with a clear hatch and dry insulation to top up usually costs towards the lower end of the range. A larger detached property, a post-war semi-detached house with an extension roof to insulate, or a terrace with boarding to lift costs nearer the upper end. Floor area, access and any boarding to lift determine the labour in the quotation. 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 Basingstoke.
Can a grant pay for loft insulation in Basingstoke?
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. In Basingstoke the properties most likely to hold under 100mm of insulation are the 1960s-80s estate properties and the post-war semi-detached houses. Their original mineral wool has settled since installation. We’ll help you check your eligibility at the survey and carry out a funded install under the scheme.
Which Basingstoke homes gain most from new loft insulation?
The Basingstoke homes that gain most from new loft insulation are the 1960s-80s semi-detached and detached properties with their original insulation. That material has settled below 100mm, and raising it to 300mm of Knauf Earthwool makes the largest difference to the heating bill. The pre-1919 solid-wall terraces in the town centre gain nearly as much. Their walls have no cavity to fill, which makes the loft the usual first insulation measure for those properties. We measure the existing depth at the survey, and the quotation specifies the material and the finished depth.
Do I need to empty my Basingstoke 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 Basingstoke 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 Basingstoke?
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 Basingstoke and the surrounding area, and our Basingstoke service area page lists the neighbourhoods we cover for insulation work. Tell us when you book if the loft contains boarding or stored possessions, because we need clear joists to measure the insulation depth.
