Loft Insulation Andover
Loft insulation for Andover homeowners
At Loft Insulation Specialists, we help Andover homeowners cut heating bills with loft insulation installed to 300mm of Knauf Earthwool or Superfoil. Most Andover properties date from the 1960s council-built overspill estates or the 2000s estates such as Picket Twenty. The 1960s houses have a standard pitched roof with conventional loft access, and their original insulation has settled below 100mm. The Georgian and Victorian properties of the conservation-area core have solid masonry walls, which leaves loft insulation as the main measure available 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 Andover homeowners benefit from Loft Insulation
Every Andover 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 council-built estates the first decision matters most, because the original insulation has settled and only dry, flat material 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 Andover homes
Most Andover lofts belong to the post-1960 estates, and on the 1960s council-built overspill estates the original mineral wool has settled below 100mm. Their standard pitched roofs give conventional loft access for a top-up installation over the settled layer. The 2000s estates, including Picket Twenty, were insulated to a later specification and usually need a top-up only. Flats make up 18.2% of the town’s properties and have no individual loft access. The Georgian and Victorian properties in the conservation-area core have solid masonry walls under pitched roofs with gables and chimney stacks. Any insulation in those lofts was added after construction and is often thin or missing.

How our Loft Insulation service works in Andover
Take a look below to find out how our Loft Insulation service works in Andover,
- 1
Book your free Andover survey
Book a free, no-obligation survey and we visit your Andover 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 Andover 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 Andover?
Loft insulation in Andover 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 2000s estate property at Picket Twenty with dry insulation to top up costs towards the lower end. A 1960s council-built property costs more where the settled original layer is damp. Damp material comes out before the new material goes in. A conservation-area property with boarding on the joists to lift reaches 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 Andover.
Can a grant pay for loft insulation in Andover?
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 1960s council-built estates are the Andover homes most likely to hold under 100mm, because the mineral wool laid at construction has settled. We’ll help you check your eligibility at the survey and carry out a funded install under the scheme.
Which Andover homes gain most from new loft insulation?
New loft insulation makes the largest difference on Andover’s 1960s council-built estates. The layer laid at construction has settled below 100mm, and we bring it to 300mm with additional Knauf Earthwool over the dry material. The Georgian and Victorian properties in the conservation-area core gain nearly as much. Solid masonry walls leave no cavity to insulate, and the loft floor takes 300mm without any exterior change. The 2000s properties at Picket Twenty gain least, because their insulation already meets a later specification. The quotation follows the survey and names Knauf Earthwool or Superfoil with the finished depth.
Do I need to empty my Andover 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 Andover 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 Andover?
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 Andover and the surrounding area, and our Andover service area page lists the neighbourhoods we cover for insulation work. Mention at booking whether the loft floor is boarded, because the survey measures the insulation between the joists and boarding covers them.
