What customers say

Based on genuine customer reviews

Interglow Ltd is described as offering loft, cavity wall and external insulation work alongside boiler installation and repair, and customers frequently focus on the quality of the finished result. Several reviewers note that the company responded quickly to enquiries and that fitters turned up when arranged for both quotations and installations.

The workmanship itself attracts consistent praise, with lofts said to look well finished and installations described as efficient and professional, while follow-up visits to check the results are also mentioned. One thing mentioned again and again is the helpfulness of the initial conversation, with questions answered in plain terms and decisions left to the householder rather than pushed through. When boilers have failed, an engineer is reported to have attended promptly and dealt with the fault.

Politeness and respect for property are recurring themes, including one fitter who wore a mask and kept his distance during the pandemic. Against this, accounts of survey visits without a follow-up quotation, of cavity wall work falling short of expectations and of appointments cancelled without notice recur across the lower-rated feedback, and communication around scheduling and quotes is the most common source of dissatisfaction. Loft insulation remains the job most often mentioned in positive terms.

A Travel Narrative18 December 2025

Disorganised and unprofessional I booked a time for a quote, taking time off to schedule this. They contacted me on the day, 30 mins after the scheduled time, to let me know that no one was available. I told them that I didn’t want to proceed with them given they’d been so disorganised and didn’t communicate. They then proceeded to bombard us with phone calls to book, despite me already telling them that I didn’t want to proceed. When I called to remind them of this, they hung up. I think that speaks volumes about the kind of service you can expect. Judging by the other recent review, it looks like we dodged a bullet.

Interglow came out to do a quote for us on 12/10, a month and a half later, despite several chasing calls, I have not received a quote for the work. I wouldn't bother wasting your time with them.

This is ridiculous and pathetic agency assigned by councils agent Osborne for EPC. They gave consecutive 3 weeks for a day appointment and we took unpaid day offs for them and they failed to attend any of those and we lost earnings for 3 days. No one forcing them to do this job. They are highly paid by Dacorum council but their service is very very poor and disappointing. My humble request to any council NOT TO RECRUIT THIS AGENCY EVER.

I Used Interglow to carry out a EPC on our property due to selling our home and it had run out, at the time of the check being done it was assumed the walls were solid brick. We were then informed by a surveyor that it was actually cavity wall, which was then proved by removing 2 core hole vents which went though the walls. When Interglow were informed of this and proof sent via photos they disregarded this fact and were unwilling to accept this was the case due to the brick formation of the property, and unwilling to re check and up update the EPC. It wasn’t until we looked to get this re done by another assessor they finally accepted to re visit and re look at the walls. But even though we had 2 core hole vents to prove the property was cavity wall and insulated they still thought it necessary to drill a hole in our wall to check for themselves and charge for the work.
