Insulation, solar and heat pumps across Huntingdon — PE28 and PE29 growth-corridor retrofits

For most Oxmoor households, yes. Oxmoor's 1960s-70s stock is almost all cavity-walled, much of it with unfilled cavities losing around a third of the home's heat through the walls. If you receive a qualifying benefit (Universal Credit, Pension Credit, Income Support, ESA, Housing Benefit and others) and the EPC is D-G, ECO4 pays for the full install. GBIS extends that to most EPC D-G homes in council tax bands A-D without the benefit test, and a lot of Oxmoor sits in bands A-C. Installation takes a single day. Typical savings are £250-£450 a year on heating, and the EPC usually lifts one band. We submit all the paperwork on your behalf — you sign one consent form.

Yes, with the right spec. Godmanchester has a substantial conservation area and several Grade II listed properties — Georgian townhouses, Victorian riverside villas, older timber-framed cottages. External wall insulation is rarely permitted on listed frontages because it alters defining detail, but internal wall insulation using breathable systems (wood fibre, calcium silicate, aerogel) is widely accepted and protects the historic fabric. We handle the Listed Building Consent application end to end, coordinate with the conservation officer and use lime-based, vapour-open build-ups to avoid interstitial condensation. Loft insulation at joist level is almost always permitted. ECO4 funding still applies for eligible households in listed buildings.

For most Stukeley Meadows plots, yes. Huntingdon sits at roughly 1,030-1,080 kWh/kWp annual yield — strong by UK standards, comparable to much of the south-east. A typical 4 kWp south-facing array generates 4,100-4,300 kWh/year, covering 30-50% of a new-build 3-4 bed's electricity use. Pair it with a 5 kWh battery and self-consumption rises to 70-85%; Smart Export Guarantee pays around 15p/kWh on the surplus. New-build roofs are a clean slate — modern trusses, fresh tiles, no hidden issues — so installation is quick, 1-2 days on site. If you're planning a heat pump or EV charger down the line, size the system to 5-6 kWp plus a 10 kWh battery to cover the extra load.

Usually yes. Parts of Buckden, Brampton and the outer Huntingdon hamlets sit off the mains gas grid, meaning homes are often on oil, LPG or old electric storage heaters — all pricey to run. A well-specced air-source heat pump runs at 300-400% efficiency and typically cuts annual heating costs by £600-£1,200 on a 3-bed rural Cambridgeshire home. The Boiler Upgrade Scheme pays £7,500 off the install regardless of income, bringing typical installed cost to £4,000-£7,000. For older fabric, we do a full MCS heat loss calc at the survey and uprate radiators where the existing ones won't work at heat pump flow temperatures — this is where cheap installs go wrong. Installation is 2-3 days on site after a 3-4 week BUS approval window.

Most PE28-PE29 surveys are booked within 5 working days of the first call. Loft and cavity installs finish in a single day and usually happen 1-2 weeks after approval. External wall insulation takes 5-10 days on site. Solar plus battery is 1-2 days. Air-source heat pumps are 2-3 days on site, with a 3-4 week wait for Boiler Upgrade Scheme approval before we start. Your surveyor gives you a firm start date and total duration at the end of the survey, plus a written quote that shows exactly what's funded by grants and what (if anything) you pay. You get one project coordinator and one named installer from first call through sign-off.
